Technical Field

The invention relates to a modular system according to the preamble of claim 1. The invention also relates to a harvester according to the preamble of claim 11 and to a method according to the preamble of claim 13 for producing at least one transmission in a modular system.

Background

In order to drive the working mechanism of an agricultural harvester, a wide variety of continuously variable transmissions embodied as wrap transmissions are used. The continuously variable transmission is also referred to as variator transmission.

Such a continuously variable transmission comprises the following basic components: the driving disc set and the driven disc set are respectively provided with two conical adjusting discs; a torque-transmitting component on which the adjusting disks of the drive disk set and the driven disk set are arranged, wherein the torque-transmitting component comprises a drive shaft, a hub and a hollow-cylindrical transmission section, wherein at least one adjusting disk of the drive disk set and of the driven disk set is arranged on the respective drive shaft in an axially movable manner.

A continuously variable transmission of the type described above is known from DE 19802605 a 1. The drive disk set has a stationary conical adjusting disk and a movable adjusting disk, which is in driving connection with a driven disk set via a belt, which also has a stationary conical adjusting disk and a movable adjusting disk. The fixed control disk of the drive disk stack is arranged on the drive shaft and the fixed control disk of the driven disk stack is arranged on the driven shaft, wherein the drive shaft or the driven shaft and the respective fixed control disk arranged thereon are embodied in one piece. The respective movable adjusting disks of the drive disk set and the driven disk set are embodied in one piece with a hollow-cylindrical section, by means of which the respective movable adjusting disks are arranged on the drive shaft or the driven shaft in order to be movable only in the axial direction by means of the spherical grooves of the spherical-tenon coupling.

Such a continuously variable transmission is used to drive different working units of a harvester, wherein the continuously variable transmission is used both for driving the respective working unit and for harvesters of different power classes or product lines, said continuously variable transmission being adapted to the harvester according to the speed of rotation. The necessary complexity of the continuously variable transmission resulting therefrom, in particular the integral embodiment of the drive shaft and the fixed control disk or of the hollow-cylindrical section and of the control disk which can be moved by means of the hollow-cylindrical section (as is known from the cited prior art), results in: this is cost-intensive for different product lines of harvesters and for the provision of individually configured continuously variable transmissions within these product lines. Furthermore, the integrated embodiment requires special production technical feasibility. In the production of harvesters of different power levels or product lines, therefore, high production-technical and logistical expenditure are associated with the harvesters being equipped with a continuously variable transmission according to DE 19802605 a 1.

Disclosure of Invention

The invention is based on the object of providing a modular system and a method for producing at least one transmission module in a modular system of the type mentioned at the outset, by means of which the provision of a continuously variable transmission embodied as a transmission module for harvesters of different power classes or product families or at least one harvester with different working mechanisms can be simplified and made more cost-effective.

According to the invention, this object is achieved by a modular system having the features of claim 1, a harvester according to claim 11 and a method according to claim 13 for producing at least one transmission module in a modular system.

Advantageous embodiments are the subject matter of the dependent claims.

According to claim 1, a modular system is proposed, comprising at least one continuously variable transmission for driving at least one working mechanism of a harvester, wherein the at least one continuously variable transmission comprises the following basic components:

a drive disk set and a driven disk set, each having two conical adjusting disks,

a torque-transmitting member on which the set of driving disks and the set of driven disks are arranged, wherein the torque-transmitting member comprises a drive shaft, a hub and a hollow-cylindrical transmission section, respectively,

wherein at least one adjusting disk of the drive disk set and the driven disk set, respectively, is arranged on the respective drive shaft in an axially displaceable manner,

in this case, at least two transmission modules can be formed by varying these basic components, which form different continuously variable transmissions for the agricultural harvesters of the n product lines, wherein the at least two basic components provided for guidance and force transmission are embodied essentially identically in design. The number n of product series corresponds here to a value greater than or equal to 1. By means of the modular system, at least two transmission modules can be constructed on the basis of six basic components by suitable combination of these basic components with one another, by means of which different rotational speed ranges are provided. In this case, a simplification in terms of the production of the continuously variable transmission and in terms of the flexibility with which different rotational speed ranges for different working mechanisms of at least one harvester within a product series can be achieved by at least two transmission modules is achieved by the substantially structurally identical embodiment of the transmission module, which is provided with the two basic components for guiding and force transmission. At least two transmission modules can be realized: different continuously variable transmissions made within a product line and different continuously variable transmissions made throughout multiple different product lines of an agricultural harvester. The term "transmission module" in the sense of the present invention is understood to mean the following continuously variable transmission: the continuously variable transmission has components for guiding and force transmission that can be interchanged.

The continuously variable transmission known from the prior art is not only individualized within one product series of the harvester for different working mechanisms, but also individualized with respect to different product series of the same type of harvester, while the modular system according to the invention for at least one transmission module can be used in a plurality of product series of the same type of harvester.

Preferably, the drive shaft can be embodied as a hollow shaft.

Preferably, the adjusting disks of the drive disk set and of the driven disk set of the transmission module can have a uniform structural configuration. A uniform structural configuration is understood to mean the following geometry of the adjusting disk: the geometry is consistent within one transmission module and throughout at least two transmission modules. In particular, a geometry of the adjusting disk that is as simple as possible is provided. In particular, the adjusting disks of the drive disk set and the driven disk set are rotationally symmetrical. The adjusting disks of the drive disk set and the driven disk set have a substantially truncated-cone-shaped cross section. This enables cost-effective production, for example by means of a prototype process, in particular by casting. In this case, the adjusting disk can be releasably connected to a torque-transmitting component, which directly receives the adjusting disk, in particular by a screw connection.

Advantageously, the hollow-cylindrical transmission sections are embodied identically on the drive side and the output side of the transmission module. The hollow-cylindrical transmission section can preferably be designed on the drive side and the driven side for receiving corresponding adjusting disks of the drive disk set and the driven disk set, which adjusting disks are each arranged in a stationary manner on the drive shaft. This makes it possible to greatly simplify the structurally identical embodiment of the hollow-cylindrical transmission section on at least two transmission modules.

According to an advantageous embodiment, the adjusting disks and the hollow-cylindrical transmission sections of the drive disk set and the driven disk set can be interchanged within a transmission module. In this case, the adjusting disks of the drive disk set and the driven disk set are exchanged in pairs.

According to a further advantageous aspect, the hydraulically actuatable adjusting devices of the two transmission modules for axially displacing at least one of the adjusting disks of the drive disk stack can be embodied identically in construction.

Preferably, the adjusting disk can be embodied with an annular flange comprising a uniform size. By means of the annular flange, the adjusting disk can be fastened both to the respective transmission section on the drive side and on the output side of the transmission module and to its respective hub.

In particular, the respective drive disk set and driven disk set of the at least two transmission modules can each have an adjusting disk with a uniform outer diameter. A defined rotational speed range can thereby be generated within which the operating means driven by the transmission module can be operated. One transmission module can have an adjusting disk for the driving disk set and the driven disk set, which adjusting disk comprises a first outer diameter, and at least one further transmission module can have an adjusting disk for the driving disk set and the driven disk set, which adjusting disk comprises a second outer diameter. By adjusting the different outer diameters of the disks, which are identical for the drive disk set and the driven disk set of the respective transmission module, at least two transmission modules can provide at least two rotational speed ranges which differ at least in part from one another.

Preferably, the adjusting disks of the drive disk set and/or the driven disk set can be exchanged between at least two transmission modules. The adjustability of the control disk between at least two transmission modules increases the flexibility and versatility with regard to the rotational speed range that can be generated.

For this purpose, the outer diameter of the adjusting disks of the drive disk set and/or the driven disk set can be varied within at least two transmission modules. The drive disk set and the driven disk set of the respective transmission module can have an adjusting disk with a first outer diameter and an adjusting disk with a second outer diameter, the first outer diameter being greater than the second outer diameter. The rotational speed flexibility required for different product lines of the harvester is transferred to a simplified geometry of the control disk with a uniform structural design.

In order to simplify the assembly within the respective transmission module and the adjustability between at least two transmission modules, the adjusting disks of the respective drive disk set or driven disk set can be fastened to the hub or hollow-cylindrical transmission section by means of a releasable connection, in particular a screw connection.

Preferably, the adjusting disk and the transfer section can be designed as a casting. This enables cost-effective production of large numbers of parts.

According to claim 11, a harvester is proposed with at least one working mechanism which can be driven by at least one continuously variable transmission, wherein the at least one continuously variable transmission is designed as a transmission module produced with the aid of the modular system according to one of claims 1 to 10.

In particular, at least one harvester can be embodied as a combine harvester. The combine harvester has a plurality of working mechanisms which are preferably driven by means of a belt drive. In order to be able to drive at least some of the working mechanisms variably in rotational speed, at least two transmission modules can be used. Due to the combinability of the at least two basic components (control disk and hollow-cylindrical section) with respect to one another, the at least two transmission modules can be flexibly adapted to the rotational speed ranges which are specific to the different working mechanisms which are operated within said specific rotational speed ranges.

At least one of the at least two transmission modules can be used to drive a working mechanism of a harvester of a product series, which working mechanism is embodied as a front-end (or attachment, Vorsatz), a threshing and separating device and/or a cutting device. For driving these working mechanisms, different rotational speed ranges are required, which can be generated by at least two transmission modules. In particular, the at least two transmission modules can be used to drive at least one threshing cylinder of the threshing and separating device and/or a conveying mechanism of the cutting device, which is designed as a cutting rotor, through the product line.

The object set forth at the outset is achieved by a method for producing a continuously variable transmission in a modular system according to claim 13.

According to claim 13, a method is proposed for producing at least one transmission in a modular system, wherein at least one agricultural harvester is equipped with at least one continuously variable transmission for driving at least one working mechanism of the harvester by means of the modular system, wherein the at least one continuously variable transmission comprises the following basic components:

a drive disk set and a driven disk set, each having two conical adjusting disks,

a torque-transmitting member on which the set of driving disks and the set of driven disks are arranged, wherein the torque-transmitting member comprises a drive shaft, a hub and a hollow-cylindrical transmission section, respectively,

in this case, the at least one adjusting disk of each of the drive disk set and the driven disk set is arranged on the respective drive shaft in an axially displaceable manner, wherein at least two transmission modules are formed by a variation of these basic components, which form different continuously variable transmissions for the agricultural harvesters of the n different product lines, wherein the two basic components of the basic components for guiding and force transmission are produced essentially identically in terms of construction. The number n of product series corresponds here to a value greater than or equal to 1.

In particular, the adjusting disk can be produced in a uniform geometry, and the transfer section can be produced as a substantially structurally identical component.

Furthermore, the adjusting disk can be manufactured with at least an annular flange having a uniform size. In this way, the pair-wise adjustability between the drive disk set and the driven disk set occurs between at least two transmission modules both with the same outer diameter of the adjusting disks and with different outer diameters.

The invention will be explained in more detail below on the basis of embodiments shown in the drawings.

It shows that:

FIG. 1 is a schematic view of the harvester;

FIG. 2 is a continuously variable transmission for a harvester configured as a transmission module;

FIG. 3 is a cross-sectional view of a drive disk pack of the first transmission module according to FIG. 2;

Detailed Description

In fig. 1, a harvester embodied as a self-propelled combine harvester is designated by 1, which has a cab 2, a grain compartment 3 located behind the cab, and an internal combustion engine 4 located immediately behind the grain compartment. Furthermore, the mobile harvester 1 has in its front region a harvesting attachment 5, which is only partially illustrated and is configured, for example, as a grain harvesting machine or as a rape harvesting machine. It is also possible to use a corn harvesting attachment as harvesting attachment 5, which detects the corn stalks and which separates the corn cobs from the corn stalks by means of a picking device.

The harvesting attachment 5 detects the straw to be harvested by means of the winch 6 and cuts it off near the bottom by means of a mowing device, not shown in detail, and the harvested material is then transported by the transverse auger 5a into the middle region of the harvesting attachment 5. The harvest passes from the middle area of the harvesting attachment 5 into an inclined conveyor 7, which feeds the harvest to a threshing and separating device 8. The threshing and separating device 8 is constructed as a multi-drum assembly of a tangential threshing machine and consists of a pre-acceleration drum 9, a threshing drum 10 and a cutting drum 11. These drums 9, 10 and 11 are provided with cutting baskets 9a, 10a and 11a, respectively. The harvested grain or fruit passes through the cutting baskets 9a, 10a and 11a onto the preparation floor 12, through which it is fed to the sieve of the refining apparatus 13, which moves in a vibrating manner. A refining blower 14, which generates an air flow in the region of the screen and thus conveys the chaff and short straw out of the harvester 1, interacts with the refining device 13. The grains or fruit that pass through the screen of the refining device 13 pass into a grain screw conveyor 15, which transports the grains or fruit to a grain elevator, not shown in detail, that is connected to the grain bin 3.

In the case of the harvester 1 shown in fig. 1, this cutting device 16 for cutting the remaining grain has at least one drum-like conveyor 17, also referred to as a separating rotor, which extends in the longitudinal direction of the harvester 1, the conveyor 17 can also comprise two separating rotors, depending on the power stage or product series of the harvester 1, alternatively, the cutting device 16 of the other power stages or product series of the harvester 1 can also be embodied as a pick breaker (Hordensch ü ttler).

The drum-type conveying device 17 is also radially surrounded by a cutting housing 18, which has a cutting opening, not shown in detail, in its lower region and is closed, i.e., impermeable, in its upper region. The remaining grain, chaff, ears and possibly straw pass through the aforementioned openings of the cutting housing 18 onto a return floor 19 which supplies these components to the refining apparatus 13. The constituents of this harvest flow that have been cut out by the sieve of the refining device 13 (for example, ears that have not been completely threshed) pass to an auger 20, which feeds these constituents of the harvest to a return device, not shown in detail

The return device conveys these components of the harvest back to the threshing and separating device 8. The wheat straw conveyed by the cutting housing 18 exits the cutting housing at its rear end where it reaches the straw chopper 21.

Next, the harvesting attachment 5, the threshing and separating device 8 or the conveying mechanism 17 are simplified to be written as working mechanism 22. The drive of the working devices 22 is effected by means of at least one main belt drive of the harvester 1. In this case, for the rotational speed-variable driving of a single operating element 22, i.e. the driving of at least two operating elements 22 in different rotational speed ranges, provision is made for: the working mechanisms are each drivingly coupled to at least one main belt drive via a continuously variable transmission in the form of a wrap-around transmission. The continuously variable transmission is also used within the working mechanism 22 when it comprises a plurality of driven components and these components operate at different rotational speeds, but in a defined relationship with respect to one another. This is the case, for example, in the following threshing and separating device 8: the pre-acceleration cylinder 9 and the threshing cylinder 10 of the threshing and separating apparatus operate in a fixed rotational speed relationship with respect to each other. The rotational speed of the threshing cylinder 10 can be varied in order to achieve threshing of the harvest with different strengths depending on the type and characteristics of the harvest.

In addition, the harvesters 1 of different power classes or product lines differ in particular by the correspondingly provided drive power of the internal combustion engine 4, the maximum achievable crop throughput of the harvester 1, but also by the design and configuration of the working mechanism 22. The degree of complexity of the continuously variable transmission provided for the working mechanism 22 is correspondingly high.

Fig. 2 shows a first transmission module 30 designed as a continuously variable transmission 31 and a second transmission module 30 'designed as a continuously variable transmission 31' for a harvester 1. The continuously variable transmission 31, 31' comprises a drive disk set 32 and a driven disk set 33, which each have two conical adjusting disks 36a, 36 b; 37a, 37b, which are rotatable about axes of rotation 39a, 39b, respectively. At least one adjusting disk 36b, 37b of the drive disk set 32 and the driven disk set 33 is designed to be adjustable in the axial direction (i.e. along the respective rotational axis 39a, 39 b). A wedge belt 34 extends between the adjustment discs 36a, 36b of the driving disc set 32 and the adjustment discs 37a, 37b of the driven disc set 33. The drive disk pack 32 is equipped with a hydraulically actuatable adjusting device 35, by means of which at least the adjusting disk 36b can be moved axially. All the adjustment disks 36a, 36b of the first transmission module 30; 37a, 37b each have the same outer diameter D1. All the adjusting disks 36a, 36b of the second transmission module 30'; 37a, 37b each have the same outer diameter D2.

The second transmission module 30 'embodied as a continuously variable transmission 31' also comprises a drive disk set 32 and a driven disk set 33, which each have two conical adjusting disks 36a, 36 b; 37a, 37b, which are rotatable about axes of rotation 39a, 39b, respectively. At least one adjusting disk 36b, 37b of the drive disk set 32 and the driven disk set 33 is embodied so as to be adjustable in the axial direction (i.e. along the respective rotational axis 39a, 39 b). A wedge belt 34 extends between the adjustment discs 36a, 36b of the driving disc set 32 and the adjustment discs 37a, 37b of the driven disc set 33. The drive disk pack 32 is equipped with a hydraulically actuatable adjusting device 35, by means of which at least the adjusting disk 36b can be moved axially. All the adjusting disks 36a, 36b of the second transmission module 30'; 37a, 37b have the same outer diameter D2, which outer diameter D2 is different from the adjustment discs 36a, 36b of the first transmission module 30; 37a, 37b, and an outer diameter D1.

The illustration in fig. 3 shows a sectional view of the drive disk stack 32 of the first transmission module 30 according to fig. 2. The disk pack 32 of the first transmission module 30 shown in fig. 3 differs from the disk pack 32 of the second transmission module 30' only in the outer diameter D1 or D2 of the adjusting disks 36a, 36 b. The first transmission module 30 comprises a torque-transmitting component to which the transmission section 38 is connected in a rotationally fixed manner, as well as a drive shaft embodied as a hollow shaft 40, to which the transmission section 38 is connected. A tenon 40a, which is a component of a tongue-and-groove connection that can be mated with a drive shaft, not shown, is located inside the hollow shaft 40. The hollow-cylindrical transfer section 38 has a substantially U-shaped cross section and is embodied rotationally symmetrically. A hub 41 is arranged on the hollow shaft 40 as a further torque-transmitting component, said hub being axially displaceable on the hollow shaft 40 along the axis of rotation 39 a. The hub 41 is connected to the hollow shaft 40 in a rotationally fixed manner. The hub 41 is connected with the adjustment device 35 such that the hub 41 is moved in the axial direction.

The transfer section 38 is arranged coaxially with respect to the hollow shaft 40, wherein it surrounds the hollow shaft 40 in sections in the axial direction. The transfer section 38 is provided with a through-hole having an inner diameter equal to or greater than the inner diameter of the hollow shaft 40. In order to connect the transfer section 38 to the hollow shaft 40, the transfer section 38 has a first flange section 38a extending radially inward on one side, by means of which the transfer section 38 is supported axially on the free end of the hollow shaft 40. The transmission section 38 is connected in a rotationally fixed manner by a first flange section 38a by means of a screw connection 43. The transfer section 38 also has a second flange section 38b extending radially outward, which is configured axially spaced apart from the first flange section 38 a.

The adjusting disk 36a is fastened releasably to the second flange section 38b by means of a screw connection 42 arranged in the circumferential direction. The adjusting disk 36a is arranged fixedly on the hollow shaft 40 by means of a connection point with the second flange section 38 b. The adjusting disk 36b of the drive disk stack 32 is arranged on the hub 41 in a rotationally fixed manner. The adjusting disk 36b can be moved in the axial direction on the hollow shaft 40 by means of the hub 41. The adjusting disk 36b is releasably connected to the hub 41 via an outer flange section 41a on the hub and also via a screw connection 42. A screw connection 44 is also provided, by means of which the adjusting disk 36b, the hub 41 and the adjusting device 35 are connected to one another.

As can be seen from the illustration in fig. 3, the two adjusting disks 36a, 36b of the drive disk stack 32 of the first transmission module 30 are of identical design. The adjusting disks 36a, 36b are designed substantially in the form of truncated cones. The arrangement of the adjusting disks 36a, 36b on the hollow shaft 40 is mirror-symmetrical, so that a substantially V-shaped gap is formed between the adjusting disks 36a, 36b, in which the wedge belt 34 runs around. Each adjusting disk 36a, 36b has an annular flange 45, which forms a respective connection point for connection to the second flange portion 38 or hub 41, to which the adjusting disks 36a, 36b of the drive disk stack 32 are fastened. Both adjusting disks 36a, 36b have the same outer diameter D1.

The radial section 46, which is embodied at an angle, engages on the annular flange 45 of the respective adjusting disk 36a, 36 b. The radial sections 46 of the adjusting disks 36a, 36b facing each other form a substantially V-shaped gap due to the respective inclination.

Fig. 4 shows a sectional view of the driven disk stack 33 of the second transmission module 30' according to fig. 2. The group of driven discs 33 of the first transmission module 30 differs from the group of driven discs 33 of the second transmission module 30' shown in fig. 4 only by the outer diameter D1 or D2 of the adjusting discs 37a, 37 b. The same reference numerals are used for components or parts that are identical or identical in construction to the components or parts of the drive disk stack 32. The driven disk pack 33 comprises two adjusting disks 37a, 37b which are embodied identically in construction to the adjusting disks 36a, 36b of the drive disk pack 32. The structural identity in the sense of the present invention means that at least the geometry of the adjusting disks 36a, 36b, 37a, 37b is identical. In particular, the respective annular flanges 45 of the adjustment discs 36a, 36b, 37a, 37b are of uniform size. Both adjusting disks 37a, 37b have the same outer diameter D2. Furthermore, a likewise identically designed or corresponding transmission section 38 is provided, which is releasably connected to the hollow shaft 47 by means of a screw connection 42. The adjusting disk 37a is arranged in a stationary manner on the transfer section 38. The fastening of the adjusting disk 37a on the transmission section 38 between the ring-shaped flange 45 and the second flange section 38b is effected by means of a screw connection 42.

A hub 48 is arranged on the hollow shaft 47 in a rotationally fixed manner, said hub being displaceable in the axial direction along the rotational axis 39 b. The hub 48 is of substantially hollow-cylindrical design and has a radial shoulder 49. The adjusting disk 37b is releasably connected to the radial shoulder 49 by means of a screw connection 42. A spring disk 47a, on which a sleeve-shaped section 47b is arranged, for example by screwing, is located on the end of the hollow shaft 47 opposite the transmission section 38. A pressure spring 50, which is arranged coaxially with respect to the hollow shaft 47, is supported between the radial shoulder 49 and the spring disk 47 a. The pressure spring 50 acts on the axially displaceable hub 48 with a spring force acting in the axial direction, which moves the two adjusting disks 37a, 37b toward one another. The sleeve-shaped section 47b surrounds the compression spring 50 in sections in the circumferential direction.

The first transmission module 30 comprises, as basic components, identically constructed adjusting disks 36a, 36b of the drive disk set 32 and of the driven disk set 33; 37a, 37b and torque-transmitting components (hollow shaft 40 or 47, hub 41 or 48 and two identically designed transmission sections 38).

In the first configuration of the first transmission module 30 according to fig. 2, the outer diameter D1 of the adjusting disks 36a, 36b of the drive disk pack 32 and the outer diameter D1 of the adjusting disks 37a, 37b of the driven disk pack 33 are selected identically. Four structurally identical setting disks 36a, 36b, 37a, 37b are used in the first transmission module 30 according to the first configuration.

It is known that the rotational speed range transmitted by the continuously variable transmission 31 can be varied with the setting disks 36a, 36b of the drive disk set 32 and the driven disk set 33; 37a, 37b vary in outer diameter D1, D2. At least one further transmission module 30' according to fig. 2, which has a different rotational speed range than the first transmission module 30, can be realized in the following manner: the adjusting disks 36a, 36b of the drive disk stack 32 and the adjusting disks 37a, 37b of the driven disk stack 33 each have the same outer diameter D2, wherein the outer diameter D2 of the adjusting disks 36a, 36b, 37a, 37b of the second transmission module 30' is smaller than the outer diameter D1 of the adjusting disks 36a, 36b, 37a, 37b of the first transmission module 30. Thus, at least two transmission modules 30, 30 'are provided, which can be applied to different transmissions 31, 31' for different working mechanisms 22 within one product series or n different product series for the agricultural harvester 1 throughout the product series.

This results in an expansion of the combinatorial diversity: due to the uniform geometry of the adjusting disks 36a, 36b, 37a, 37b and the identical embodiment of the annular flange 45 of the adjusting disks 36a, 36b and 37a, 37b, these can be interchanged between the two transmission modules 30, 30'. The drive disc group 32 according to fig. 3 can therefore be realized with an adjusting disc 36a, 36b having an outer diameter D1, and the driven disc group 33 according to fig. 4 can be realized with an adjusting disc 37a, 37b having an outer diameter D2, wherein the outer diameter D1 is greater than the outer diameter D2. The opposite configuration is also possible when the adjusting disks 36a, 36b of the drive disk stack 32 have an outer diameter D2 and the adjusting disks 36a, 36b of the driven disk stack 33 have an outer diameter D1.

Thus, at least two transmission modules 30, 30 'can be formed by changing at least the basic components ( control disks 36a, 36 b; 37a, 37b, transfer section 38, hubs 41, 48 and hollow shafts 40, 47, in which at least the control disks 36a, 36 b; 37a, 37b and transfer section 38 are embodied identically in design) which form different continuously variable transmissions 31, 31' for the agricultural harvesters 1 of the n different product families, wherein two of the basic components ( control disks 36a, 36 b; 37a, 37b and transfer section 38) for guiding and force transfer are embodied identically in design or are embodied identically in design. Thereby realizing that: these basic components, which are substantially identical in construction, can be interchanged both on the drive side and on the output side of the respective continuously variable transmission module 30, 30' and also within different product lines of the harvester 1.
