Technical Field

The invention relates to the technical field of vehicles. In particular, the present invention relates to a clutch device.

Background

Clutches are important components in motor vehicle drive trains. Clutch devices typically include pressure plates, reaction plates, and friction plates. Wherein the reaction disk is connected to the gear ring in a rotationally fixed manner. Typical structures of such clutch devices are disclosed in patent documents CN 102834633B and the like. Currently, there are two main ways of connecting the driving ring gear and the reaction disk: riveting and bolting. Riveting is low cost but difficult to disassemble, while bolting is easy but costly.

Disclosure of Invention

Therefore, the present invention is to provide a clutch device that is easy to assemble and disassemble and low in cost.

The above-mentioned object is achieved by a clutch device according to the invention. The clutch device includes a transmission ring gear and a reaction plate. The clutch device further comprises a clamp spring extending along the circumferential direction and a plurality of mounting pins distributed at intervals along the circumferential direction, each mounting pin sequentially penetrates through the transmission gear ring and the reaction disk along the axial direction and is provided with a first end and a second end extending to the outer sides of the transmission gear ring and the reaction disk respectively, each mounting pin is provided with a limiting flange at the first end and a limiting ring groove at the second end, the clamp spring is clamped into the limiting ring groove of each mounting pin along the radial direction, and the limiting flange and the clamp spring fix the transmission gear ring and the reaction disk together at two sides of the axial direction respectively. The mounting pin simultaneously passes through axially aligned through holes in the drive ring gear and the reaction disk to connect the two in a torque-proof manner; the limiting flanges and the clamping springs at the two axial ends of the mounting pin respectively protrude out of the transmission gear ring and the reaction disc so as to axially restrain the transmission gear ring and the reaction disc together. The transmission gear ring and the reaction disc are stably fixed to each other, the mounting mode is simple and easy to implement, the operation is convenient, the repeated assembly and disassembly can be realized, and the production cost is low.

According to a preferred embodiment of the present invention, the circlip may have a notched portion in the circumferential direction. The snap spring is usually an annular metal sheet with a circumferential notch part, and the circumferential notch part enables the snap spring to be convenient for changing the diameter size through elastic deformation, so that the snap spring can be conveniently clamped into the limiting ring grooves of the plurality of mounting pins arranged along the circumferential direction.

According to another preferred embodiment of the present invention, when the snap spring is snapped into the retainer ring groove of each mounting pin, each mounting pin may circumferentially surround a radial outer side of the snap spring, or each mounting pin may circumferentially surround a radial inner side of the snap spring. That is, the snap spring is engaged into the retainer ring groove of each mounting pin from the inside or outside of the circumference in which these mounting pins are arranged. The arrangement mode is more convenient for dismounting the clamp spring, and the clamp spring is more stably jointed with the limiting ring groove.

According to another preferred embodiment of the invention, the plurality of mounting pins may be evenly spaced circumferentially, thereby allowing the entire device to be evenly stressed.

According to a further preferred embodiment of the invention, each limit flange may be located axially outside the drive ring gear, while each limit ring groove is correspondingly located axially outside the reaction disc, whereby the snap spring is also mounted on the side close to the reaction disc. This is because the side close to the driving ring usually has other components mounted, there is not enough space to mount the circlip, while the reaction plate itself is thicker and usually has a concave central area where there is sufficient space to mount the circlip. It is alternatively possible if required for each limiting flange to be located axially outside the reaction disk and for each limiting ring groove to be located axially outside the transmission toothed ring.

According to another preferred embodiment of the present invention, the mounting pin may be made of metal or the like. The metal material has better mechanical property and can provide higher torque transmission capability.

According to a further preferred embodiment of the invention, the mounting pin may have a constant diameter in the section between the stop collar and the stop ring groove.

According to another preferred embodiment of the present invention, the axial width of the retainer ring groove may be greater than the axial thickness of the clip spring, thereby facilitating the snap-in or removal of the clip spring into or from the retainer ring groove.

According to another preferred embodiment of the invention, the mounting pin may have a chamfer formed between an axial end face and a circumferential side face of the second end, thereby facilitating guiding the second end of the mounting pin through the through-holes in the transmission ring and the reaction plate in sequence.

Detailed Description

Hereinafter, a specific embodiment of a clutch device according to the present invention will be described with reference to the accompanying drawings. The following detailed description and drawings are included to illustrate the principles of the invention, which is not to be limited to the preferred embodiments described, but is to be defined by the appended claims.

According to an embodiment of the present invention, a clutch arrangement for a driveline of a motor vehicle is provided. Fig. 1 and 2 show a front view and a perspective view of the clutch device according to this embodiment from two different angles, respectively.

As shown in fig. 1 and 2, the clutch device includes a reaction plate 10, a transmission ring gear 20, a snap ring 30, and a plurality of mounting pins 40. The reaction plate 10 is a disc-shaped structure made of metal. The driving ring gear 20 is an annular structure with external teeth made of metal. The reaction disk 10 and the drive ring gear 20 are arranged coaxially.

The plurality of mounting pins 40 are evenly circumferentially spaced about the common axis of rotation of the reaction plate 10 and the drive ring gear 20. Each mounting pin 40 has the same structure and dimensions. The following description will be given by taking only one of the mounting pins 40 as an example.

Fig. 3 shows a perspective view of the mounting pin 40. As shown in fig. 3, the mounting pin 40 is a generally cylindrical member made of metal. The mounting pin 40 has axially opposed first and second ends 41, 42. The mounting pin 40 has a stopper flange 43 protruding radially outward at the first end 41, and a stopper ring groove 44 recessed radially inward at the second end 42. The retainer flange 43 and the retainer ring groove 44 extend circumferentially around the outer side surface of the mounting pin 40.

Referring again to fig. 1 and 2, each mounting pin 40 passes axially through a correspondingly aligned through-hole in the reaction plate 10 and the drive ring 20, respectively, to connect the reaction plate 10 and the drive ring 20 in a rotationally fixed manner. When the mounting pin 40 is mounted on the reaction plate 10 and the drive ring gear 20, the first end 41 projects axially from one side of the drive ring gear 20 and the second end 42 projects axially from one side of the reaction plate 10 such that the limit flange 43 is located axially outward of the drive ring gear 20 (as shown in FIG. 1) and the limit ring groove 44 is located axially outward of the reaction plate 10 (as shown in FIG. 2).

During installation, it is necessary to pass the second end 42 of the mounting pin 40 axially through the drive ring 20 and the reaction plate 10 in sequence from the side adjacent to the drive ring 20. Thus, to facilitate installation, the mounting pin 40 has a chamfer 45 formed between the axial end face and the circumferential side face of the second end 42, as shown in FIG. 3. The mounting pin 40 has a constant diameter in the section between the stop flange 43 and the stop ring groove 44. Particularly preferably, the entire mounting pin 40 can have a constant diameter in sections other than the stop flange 43, the stop ring groove 44 and the chamfer 45.

As shown in fig. 2, the circlip 30 extending in the circumferential direction is mounted on the radially inner side of the circumference in which these mounting pins 40 are aligned on the side close to the reaction disk 10, so that the outer peripheral edge of the circlip 30 is radially snapped into the stopper ring groove 44 of each mounting pin 40. The snap spring 30 is a metal ring piece having a notched portion in the circumferential direction, and can change the size of the diameter by elastic deformation, and thus can be easily engaged with the stopper ring groove 44 of the mounting pin 40 or detached from the stopper ring groove 44. For easy dismounting, the axial width of the limiting ring groove 44 of the mounting pin 40 is usually slightly larger than the axial thickness of the snap spring 30, especially larger than the axial thickness of the outer periphery of the snap spring 30.

The snap spring 30 is mounted on the reaction plate 10 side because the drive ring gear 20 side is typically directly abutted against other drive components, and there is insufficient space to mount the snap spring 30. While the axial dimension of the reaction disk 10 is generally larger, its radially inner side may have a recessed area for mounting the circlip 30. Of course, it is also possible to mount the latch spring 30 on the side close to the transmission ring gear 20, in the case of sufficient mounting space, i.e. the stop collar 43 of the first end 41 of the mounting pin 40 can project axially outside the reaction disk 10, while the stop ring groove 44 of the second end 42 projects axially outside the transmission ring gear 20.

In still alternative embodiments, it is also possible to provide a plurality of mounting pins 40 in a hybrid arrangement. Specifically, the limit flange 43 of a portion of the plurality of mounting pins 40 protrudes axially outward of the reaction plate 10, while the limit flange 43 of another portion of the plurality of mounting pins 40 protrudes axially outward of the drive ring gear 20. In this case, it is necessary to provide one snap spring 30 on each of the reaction disk 10 side and the transmission gear ring 20 side, and the snap spring 30 on each side is engaged with the stopper ring groove 44 on the corresponding side. In this case, the first end 41 of the mounting pin 40 and the stopper flange 43 need to be shaped, for example, to have an incomplete circular cross section so that the stopper flange 43 does not interfere with the clip spring 30 mounted on the same side. Furthermore, separately or additionally, the positions of the plurality of mounting pins 40 that engage with the same circlip 30 may also vary, i.e., the plurality of mounting pins 40 that engage with the same circlip 30 may also all be located radially inward of the circlip 30, such that the inner circumferential edge of the circlip 30 radially engages into each of the stopper ring grooves 44; alternatively, among the plurality of mounting pins 40 that engage with the same circlip 30, a part of the mounting pins 40 is positioned radially inward of the circlip 30, and another part of the mounting pins 40 is positioned radially outward of the circlip 30.

Compared with the traditional riveting installation mode, the installation mode can conveniently and repeatedly disassemble and assemble the same batch of parts, has stronger unit torque transmission capability, and can avoid quality problems easily generated in the riveting process. On the other hand, compared with the installation mode of bolt connection, the installation mode of the invention has lower cost and stronger unit torque transmission capacity.

Although possible embodiments have been described by way of example in the above description, it should be understood that numerous embodiment variations exist, still by way of combination of all technical features and embodiments that are known and that are obvious to a person skilled in the art. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. From the foregoing description, one of ordinary skill in the art will more particularly provide a technical guide to convert at least one exemplary embodiment, wherein various changes may be made, particularly in matters of function and structure of the components described, without departing from the scope of the following claims.
