Technical Field

The invention relates to an aggregate of a plurality of quick couplers according to the preamble of claim 1.

Background

A quick coupling comprising two coupling cartridges which can be actuated by a common actuating lever is known from EP 3244114B 1. The quick coupling is provided for attaching to a valve disk of a valve module comprising a plurality of directional valves. Such quick couplers are used, for example, in agricultural tractors in order to be able to quickly establish and release a hydraulic connection with a replaceable attachment device. The hydraulic hose lines are typically connected to the respective adapter barrels.

Another quick coupling is known from US 7568502B 2.

In addition, the website was visited from 3/29/2019: a large number of adapter cartridges are known on web pages that can be called under https:// www.fastercouplings.com/couplings-check-values. Within the scope of the invention, however, only the type which can be actuated by means of a joystick or which is designed in a push-pull technique is important.

Disclosure of Invention

One advantage of the invention is that the quick couplers of the aggregate can be combined with each other with any choice. This can be done not only when the assembly of quick couplers is first manufactured. Rather, it is also possible to later exchange one quick coupling for another. The quick coupling is designed such that its pitch is designed to be equal to the pitch of the valve disks of the valve module, regardless of the type of coupling cartridge used.

Despite this narrow installation space, all quick couplers can be actuated independently of one another. Furthermore, all universal adapter cartridges may be used. In addition, the first sub-quick coupling, which is the most frequently required variant, is particularly inexpensive. Furthermore, the adapter housing is formed in a particularly material-saving manner. The various quick couplers of the aggregate have many identical components and therefore they can be manufactured inexpensively despite the presence of different adapter cartridges.

According to the independent claim, all the adapter housings are formed in one piece, wherein all the adapter cartridges are each fastened directly in or on the assigned adapter housing, wherein the first and second working interfaces, the fastening bores and, if present, the oil leak interfaces are formed identically on all the quick couplers with regard to their shape and their relative position within the respective assigned connection face, wherein at least two quick couplers of the aggregate have different adapter cartridges, wherein all the adapter housings can be arranged side by side with a constant pitch with respect to the longitudinal axis and the same pitch for all the quick couplers of the aggregate. The mentioned pitch is preferably between 100% and 130% of the maximum outer diameter of the maximum adapter cylinder. The residual wall thickness between the adapter cylinder and the outer surface of the adapter housing is preferably designed to be as small as technically possible.

If any quick coupling of the aggregate is assembled into an assembly, the center axis of the coupling cylinder can preferably be arranged in two parallel straight lines, viewed in the direction of the longitudinal axis. The central axis of the adapter cylinder is preferably oriented parallel to the vertical axis. The fixing perforations preferably run parallel to the vertical axis.

Advantageous developments and improvements of the invention are specified in the dependent claims.

It can be provided that the aggregate comprises a plurality of first quick-action couplings, wherein a coupling surface is arranged on a coupling housing of the first quick-action couplings in parallel opposition to a coupling surface, wherein two corresponding coupling cartridges are arranged in the coupling housing in a manner sunken in relation to the coupling surface, wherein the coupling cartridges are accessible in the region of the coupling surface for connecting a counterpart, wherein a spacing between the coupling surface and the coupling surface in the direction of the vertical axis is formed identically on all first quick-action couplings, wherein at least two first quick-action couplings have different coupling cartridges.

It can be provided that a protective cover is assigned to each adapter cylinder of the first quick adapter, which protective cover rests at least indirectly on the coupling surface, wherein the protective cover is pivotable relative to a first axis of rotation arranged parallel to the vertical axis, wherein the protective cover completely covers the assigned adapter cylinder in at least one pivot position, wherein all protective covers are identically designed independently of the kind of assigned adapter cylinder. The protective cover can be placed directly on the coupling surface. However, it is also conceivable for the two protective covers of the quick coupling to be fastened to a common plate-like intermediate part, the intermediate part resting on the coupling surface.

It can be provided that the first quick-action couplings each have at least one actuating lever, wherein all actuating levers are formed identically with respect to their shape visible from the outside, wherein each actuating lever has a second axis of rotation arranged parallel to the transverse axis, wherein the spacing between the second axis of rotation and the assigned connecting surface is formed differently for at least two actuating levers assigned to different coupling cylinders. Preferably, the first quick coupling has two levers arranged on opposite sides of the coupling housing with respect to the transverse axis. The two actuating levers can be connected to one another in a rotationally fixed manner, so that with the two actuating levers, two adapter cylinders can be actuated simultaneously. However, it is also conceivable for the two levers to be pivotable independently of one another, wherein one of the two adapter cylinders is assigned to each lever. When any number of the first quick couplers are assembled into an assembly, all the levers have a pitch equal to the pitch in the direction of the longitudinal axis. This spacing is preferably measured on the second axis of rotation.

It can be provided that the adapter housing of the first quick adapter has a flange section and a barrel section, respectively, which are arranged next to one another in the direction of the vertical axis, wherein they are separated from one another by a first groove arranged externally on the adapter housing, wherein the adapter barrel is received in the barrel section, wherein the connection surface is arranged on the flange section, wherein the fastening bore comprises at least one first fastening bore which runs through the flange section, wherein the first fastening bore merges into the first groove. Correspondingly, a fastening means, for example a screw, can be inserted into the first fastening opening via the first recess. The coupling surface is preferably arranged on the barrel section.

Provision can be made for at least one second groove to be arranged on the outside of the shaft section, said second groove extending in the direction of the vertical axis over the entire height of the shaft section, wherein the second groove merges into the first groove, wherein the second groove is arranged such that, viewed in the direction of the vertical axis, a line of sight to the assigned first fixing opening is not blocked by the adapter housing. The second groove preferably has a constant cross-sectional shape along the vertical axis. Preferably all first fixing perforations are assigned a second recess. The second recess is preferably an integral part of the blank of the adapter housing, which is most preferably made in a casting process.

It can be provided that the first quick coupling comprises a first sub-type, for which the first recess is formed continuously around the coupling housing about the vertical axis, wherein all fixing bores are first fixing bores. Preferably, all first fixing bores are assigned a first recess. The first sub-quick coupling is preferably equipped with a first coupling cylinder having a reduced size compared to the largest coupling cylinder (second or third) of the aggregate. For example, they have a nominal size of 1/2 inches.

It can be provided that the first quick coupling comprises a second sub-category, wherein the coupling housing has a flat side which is a constituent of the flange section and the barrel section, wherein the side is formed continuously, wherein the fastening bores comprise second fastening bores which are arranged in the region of the side in question, wherein the second fastening bores extend over the entire height of the coupling housing. The second fixing perforation is preferably made by means of drilling. The second subspecies quick-coupling is preferably equipped with the largest coupling cylinder (second or third) of the aggregate. For example, the largest adapter barrel has a nominal size of 3/4 inches. The at least one second fixing perforation is preferably provided with a counter bore in the region of the coupling face. The mentioned side face is preferably not divided by the first recess into two separate part surfaces.

Provision can be made for the leakage oil to flow off at a first leakage point and at a separate second leakage point on each adapter cartridge, the second leakage point being permanently fluidically connected to the assigned leakage oil connection, the first leakage point being connected to a leakage oil channel which extends through the adapter housing in the direction of the longitudinal axis, so that the leakage oil channel produces a continuous channel when any quick-coupling of the aggregate is assembled into an assembly along the longitudinal axis. The second leak preferably leads to a clean leakage oil, which can be used further in the hydraulic circuit. The first leakage point is preferably arranged in the region of the coupling surface, where a contaminated leakage oil may occur when coupling or uncoupling the adapter cartridge, which leakage oil should no longer be conducted into the hydraulic circuit, but instead is collected in a separate container.

Provision can be made for a junction opening to be assigned in the coupling face for each adapter cylinder of the first quick adapter, wherein a third groove is arranged on the edge of the junction opening, which third groove extends in the direction of the vertical axis with a constant cross-sectional shape, wherein the third groove is fluidly connected with the oil leakage channel.

It can be provided that the intake opening is defined by a cylindrical fourth recess arranged concentrically with respect to the assigned adapter cylinder, wherein the adapter cylinder is arranged flush with the bottom of the fourth recess or projects into the fourth recess. The fourth groove is used for collecting leakage oil from the first leakage point. Otherwise, the position of the second axis of rotation relative to the connection surface can be configured identically in all first quick couplings, by a suitable choice of the depth of the fourth recess.

It can be provided that the aggregate comprises at least one second quick coupling, wherein the respective coupling cartridges each have an actuating means by means of which a coupling engagement can be released or established, wherein the respective coupling housing is designed in the form of a plate, wherein the coupling cartridge mentioned is screwed onto the coupling housing from the outside. The actuating means can be a linearly movable actuating sleeve. Adapter cartridges with a linearly movable actuating sleeve are also referred to as adapter cartridges in the push-pull technology. The coupling housing of the second quick coupling is preferably of similar design to the flange section of the coupling housing of the first quick coupling. The actuating means can also be a pivotally movable lever. The corresponding adapter cartridge is also referred to as "semi-integrated".

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination, but also in other combinations or alone without leaving the scope of the invention.

Detailed Description

Fig. 1 shows a perspective view of an assembly 10 with all quick couplers 20, 21, 22, 23, 24 of the aggregate according to the invention. The quick couplers 20 are arranged side by side at a constant pitch 14 in the direction of the longitudinal axis 11. This pitch 14 is equal to the pitch of the valve module on which the present assembly is to be added. Most quick couplers are constructed according to the first type 21, which accordingly comprises one or two operating levers (reference 92 in fig. 3, 4) which are arranged on opposite sides of the assigned coupler housing (reference 50 in fig. 3, 4) in the direction of the transverse axis 13. All the actuating levers are of identical design in terms of their shape visible from the outside and their arrangement on the adapter housing, only their position in the direction of the vertical axis 12 possibly differing due to the respectively used adapter cylinders 31, 32, 33. The vertical axis 12 is oriented perpendicular to the longitudinal axis 11, and the transverse axis 13 is oriented perpendicular to the longitudinal axis 11 and the vertical axis 12.

The first quick coupling 21 includes a plurality of first subspecies quick couplings 23. These first sub-quick couplers are each equipped with two female coupler barrels 31 having a nominal size of 1/2 inches. This is the most frequently required variation of the quick coupling 20 on the market. In contrast, this variant is particularly cost-effective. In particular, only a small amount of machining work is required on the cast blank of the adapter housing, which is designed in a particularly material-saving manner.

The first quick coupling 21 includes a plurality of second subspecies quick couplings 24. The second subspecies quick-couplers are particularly compatible with large adapter cylinders 32, 33 having a nominal size of 3/4 inches. These adapter cartridges can be formed in a female variant 32 or in a flat variant 33. However, it is also conceivable to install a coupling cartridge 31 having a nominal size of 1/2 inches into the second subspecies of quick couplers 24, that is to say if the coupling cartridge is to be replaced only later on in the field for a larger coupler, for example from 1/2 "to 3/4". For further details, reference is made to the explanation in relation to fig. 4.

In addition, the assembly 10 includes a second quick coupler 22. Its adapter housing 50 is formed according to the flange section (reference numeral 53 in fig. 3, 4) of the first quick adapter 21, wherein no oil leak connection (reference numeral 73 in fig. 2) is present. The two adapter barrels 34 are screwed into the respective adapter housings 50 in a push-pull technique. Instead of the actuating levers (92 in fig. 3 and 4), the adapter cartridges each have an actuating means 38 in the form of an actuating sleeve which can be moved parallel to the vertical axis 12 for establishing and releasing the engagement. The second quick coupler 22 is the least expensive of all quick couplers 20. In this respect, the advantage of the aggregate according to the invention is that it is not necessary to change the assigned valve disks in any way in order to be able to use this variant as well.

Fig. 2 shows a further perspective view of the assembly 10 according to fig. 1, viewed from the side opposite to fig. 1. The attachment face 70 of each quick coupler 20 can be seen. All connection surfaces 70 are formed flat and are oriented parallel to longitudinal axis 11. In the assembled component 10, the connection surfaces all lie in one plane. The adapter housings (50 in fig. 3 and 4) preferably adjoin one another with a small gap in the region of their connection faces 70, so that they can be easily oriented on the valve module. The respective contact surfaces lying opposite one another are preferably of planar design and are oriented perpendicular to the longitudinal axis 11.

For each quick coupling 20, within each connection face 70, a first working interface 71 and a second working interface 72 and four fixing perforations 74 are arranged. In addition to this, only the first quick coupling is provided with the oil leak interface 73. These interface contours 71, 72, 73, 74 are of identical design and are arranged identically in all quick couplings 20, so that the quick couplings 20 can be exchanged arbitrarily with one another.

The fixing hole 74 can be configured as a first fixing hole 75 or a second fixing hole 76. The short first fixing holes 75 are each penetrated by a fixing means 15 in the form of a short screw. The longer second fixing perforation 76 is responsible for the lack of structural space. They are penetrated by correspondingly long fastening means in the form of bolts. It goes without saying that other fastening means, such as furniture shackles, bracing bolts with perforations and pins or studs, can also be used from the side. In addition, the fastening bores 74 can be provided with an internal thread, so that a screw can be screwed in.

Fig. 3 shows a perspective view of the first sub-quick coupling 23. The adapter housing 50 comprises a flange section 53 and a barrel section 54, which are arranged side by side in the direction of the vertical axis 12, wherein they are separated from each other by a first groove 55. The connection surface 70 is arranged below on the flange portion 53, and the adapter sleeve 30 is received inside the sleeve portion 54. Preferably, the adapter sleeve 30 is arranged in accordance with the first type 31 having a nominal dimension of 1/2 inches.

The first recess 55 is formed continuously around the adapter housing 50 with respect to the vertical axis 12. Correspondingly, all four fixing bores 74 merge into the first recess 55, which is thus a first fixing bore 75. As a result, the fixing means can be introduced into the first fixing penetration 75 through the first groove 55. The fixing means is for example a socket head cap screw with a hexagonal internal structure or a quincuncial profile. The corresponding screwing tool is placed by means of a second groove 56 arranged externally on the barrel section 54. The second groove 56 extends with a constant cross-sectional shape along the direction of the vertical axis 12 over the entire height of the barrel section 54. They are arranged in alignment with the assigned first fixing perforation 75. The screwing tool mentioned can thus be easily oriented parallel to the vertical axis 12 when it is placed on the fixing means.

Furthermore, fig. 3 also shows two actuating levers 92, which are arranged on opposite sides of the adapter housing 50 in the direction of the transverse axis 13. The actuating lever 92 can be pivoted about a second axis of rotation 93, which is oriented parallel to the transverse axis 13. It is conceivable for the two actuating levers 92 to be connected to one another in a rotationally fixed manner, wherein they are then preferably oriented parallel to one another. In this case, the two adapter cylinders 30 can be operated simultaneously with each of the two operating levers. It is also conceivable for the two actuating levers 92 to be pivotable independently of one another. In this case, each lever preferably operates the respective nearest adapter cylinder. Furthermore, a single common actuating lever for both coupling cylinders can be considered.

The two adapter barrels 30 are arranged in the barrel sections 54 in a manner sunken with respect to the coupling surfaces 51, respectively. The adapter housing 50 has a cylindrical fourth recess 58, which is arranged concentrically with the assigned adapter cylinder 30. In this region, there is a first leakage point 36, at which leakage oil can occur when coupling or uncoupling the adapter cartridge 30, which leakage oil is often contaminated and therefore to be removed. Such leakage oil accumulates in the fourth groove 58. A third groove is arranged on the edge of the inlet opening 61 defined by the fourth groove 58, which third groove runs parallel to the vertical axis 12 with a constant cross-sectional shape. The fourth groove 57 is fluidly connected to an oil leakage passage 60 that extends through the adapter housing 50 between the two adapter cylinders 30 in the direction of the longitudinal axis 11. If the quick coupling 20 is assembled as an assembly, a continuous passage in the direction of the longitudinal axis 11 is created by the individual leakage oil passages 60, which are preferably connected to a collecting container in which the leakage oil of the first leakage point is collected for its disposal.

Fig. 3 also shows the height of the quick coupling 20, i.e. the distance 59 between the flat connecting surface 70 and the parallel flat coupling surface 51. This height is preferably formed identically in all the first quick couplings.

Fig. 4 shows a perspective view of the second subspecies quick coupler 24. The second subspecies quick coupling 24 is constructed identically to the first subspecies quick coupling, except for the differences explained below, so reference is made in this respect to the explanations with respect to fig. 1 to 3. In fig. 1 to 4, identical or corresponding parts are denoted by identical reference numerals.

The second subspecies of the quick coupler 24 has a coupler housing 50 with a flat side 52 that is oriented perpendicular to the longitudinal axis (11 in fig. 1). The side surface 52 is formed continuously, wherein the side surface is not interrupted in particular by the first recess 55. Correspondingly, the first recess 55 extends on the outside in a U-shaped manner on the adapter housing 50. Thus, there is more room for a large adapter cartridge 30, such as having a nominal size of 3/4 inches, inside the adapter housing 50. The installation space available is enlarged in this case, in particular in the direction of the vertical axis (reference numeral 12 in fig. 1 and 2). However, in FIG. 4, only a smaller adapter cartridge having a nominal size of 1/2 inches is shown. In this variation, the adapter cartridge can be later retrofitted to a larger 3/4 inch adapter cartridge.

The two fastening bores 74 in the region of the side faces 52 are formed as second fastening bores 76 which extend through the adapter housing 50 over its entire height. In the region of the coupling face 51, the second fixing bore 76 is provided with a counterbore 77. The second fastening bore 76 is preferably produced by means of an expensive drilling process, so that the second sub-quick coupling 24 is only used when this is necessary because of the necessary installation space inside the quick coupling 20.

Fig. 5 shows a perspective view of the intermediate piece 95 with two protective caps 90. The intermediate piece 95 is designed in the form of a plate, wherein it is preferably produced from plastic by an injection molding method. The intermediate piece rests with its flat underside against a coupling surface (51 in fig. 3 or 4), wherein the intermediate piece can be fixed there by means of a bolt 96. Two of the bolts 96 simultaneously form a rotary joint, the first axis of rotation 91 of which is arranged parallel to a vertical axis (12 in fig. 1). The two protective covers 90 are pivotable about a first axis of rotation 91. In the closed position defined by means of the end stop 94, the protective cap covers a dispensed through-hole 97 in the intermediate piece 95, which is arranged concentrically with the dispensed adapter cylinder (reference numeral 30 in fig. 3, 4). The diameter of the bore 97 is preferably smaller than the diameter of the fourth groove in order to prevent leakage oil from the first leakage point. It goes without saying that the hydraulic hose to be coupled should also be insertable through the perforation 97. This bore 97 can optionally be matched to the hydraulic hose to be coupled via a rubber sleeve.

The advantage of the aggregate according to the invention is that the assembly shown in fig. 5 can be used identically in all variants of the first quick coupling.
