Description

Technical Field

[0001] The utility model relates to the technical field of clutches, and specifically relates to a compression spring retaining ring for a highly wear-resistant clutch cover assembly. Background Art

[0002] The vehicle clutch assembly is an important component of the vehicle transmission system, including a clutch cover sub-assembly, a driven disk sub-assembly, a flywheel sub-assembly, a release bearing, etc. At present, the driven disk sub-assembly of the clutch assembly is of an integral structure, and it is difficult to achieve an ideal level in attenuating the vibration transmitted from the engine to the transmission and preventing transmission noise.

[0003] For example, the compression spring retaining ring of the clutch cover assembly with the authorization announcement number of "CN211259416U" solves the problem that the existing compression spring retaining ring of the clutch cover assembly has serious friction and greatly shortens the service life of the retaining ring. Through the elastic action of the second spring, the third retaining ring body can be elastically buffered, and then a secondary elastic buffer can be formed. After wear, the second retaining ring body can still play a supporting role. After the third retaining ring body fails, the second retaining ring body can still ensure the normal use of the retaining ring. Considering the existing compression spring retaining ring of the clutch cover assembly, the thickness of multiple retaining rings is thicker from top to bottom, making the upper end of the retaining ring vulnerable to friction and damage, resulting in low wear resistance and short service life. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of the existing compression spring retaining ring of the clutch cover assembly, and to propose a compression spring retaining ring for a highly wear-resistant clutch cover assembly.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A compression spring retaining ring for a highly wear-resistant clutch cover assembly, including a first retaining ring and a third retaining ring. A reinforcement mechanism is connected to the lower end of the first retaining ring, a splicing mechanism is connected to the outer wall of the first retaining ring. The lower end of the first retaining ring is in contact with a washer, and the lower end of the washer is fixedly connected to a connecting ring.

[0006] Preferably, the reinforcement mechanism includes a first connecting cylinder, the outer wall of the first connecting cylinder is threadedly connected to the first retaining ring, a first sliding groove is installed on the inner wall of the first connecting cylinder, the inner wall of the first sliding groove is slidably connected to a first slider, and the outer wall of the first slider is rotatably connected to a second connecting cylinder.

[0007] Preferably, a second sliding groove is installed on the inner wall of the second connecting cylinder, the inner wall of the second sliding groove is slidably connected to a second slider, the outer wall of the second slider is rotatably connected to a third connecting cylinder, and the outer wall of the third connecting cylinder is threadedly connected to the third retaining ring.

[0008] Preferably, the splicing mechanism includes a first splicing block, the outer wall of the first splicing block is fixedly connected to a first retaining ring, a screw hole is installed on the inner wall of the splicing block, the inner wall of the screw hole is threadedly connected to a first fixing screw, and the outer wall of the first fixing screw is threadedly connected to a second retaining ring.

[0009] Preferably, the outer wall of the second connecting cylinder is threadedly connected to the second retaining ring.

[0010] Preferably, the inner wall of the second retaining ring is fixedly connected to a second splicing block, the inner wall of the second splicing block is threadedly connected to a second fixing screw, and the outer wall of the second fixing screw is threadedly connected to a third retaining ring.

[0011] For the compression spring retaining ring used in the high-wear-resistant clutch cover assembly proposed by the present utility model, the beneficial effects are as follows: By passing the first fixing screw and the second fixing screw through the first splicing block and the second retaining ring and the second retaining ring and the second splicing block, the first retaining ring, the second retaining ring and the third retaining ring form an integrated spiral retaining ring, which plays a buffering effect when the first retaining ring, the second retaining ring and the third retaining ring are deformed under extrusion, and the third connecting cylinder applies a downward force to drive the second slider to slide on the second sliding groove inside the second connecting cylinder, which can play a buffering effect again, improve the contact force between the upper third connecting cylinder and the third retaining ring, and achieve the wear-resistant effect.

[0012] Since the structures of the first retaining ring, the second retaining ring and the third retaining ring are the same, the positions between the first retaining ring, the second retaining ring and the third retaining ring can be adjusted by using the first fixing screw and the second fixing screw, so that the contact between the upper retaining ring and the diaphragm spring can be in the original state, improving the overall service life.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings: Embodiment 1

[0023] Please refer to Figure 1-8 : In this embodiment, a pressure spring retaining ring for a highly wear-resistant clutch cover assembly includes a first retaining ring 1 and a third retaining ring 2. A reinforcement mechanism 3 is connected to the lower end of the first retaining ring 1, a splicing mechanism 4 is connected to the outer wall of the first retaining ring 1, the lower end of the first retaining ring 1 is in contact with a washer 5, and the lower end of the washer 5 is fixedly connected to a connecting ring 6;

[0024] The first retaining ring 1, the second retaining ring 404 and the third retaining ring 2 have the same structure. The positions between the first retaining ring 1, the second retaining ring 404 and the third retaining ring 2 can be adjusted by using the first fixing screw 403 and the second fixing screw 10, so that the contact between the upper retaining ring and the diaphragm spring can be in the original effect, improving the overall service life.

[0025] The reinforcement mechanism 3 includes a first connecting cylinder 301. The outer wall of the first connecting cylinder 301 and the outer wall of the second connecting cylinder 304 are threadedly connected to the first retaining ring 1 and the second retaining ring 404 to achieve the effect of reinforcing the first retaining ring 1 and the second retaining ring 404. The outer wall of the first connecting cylinder 301 is threadedly connected to the first retaining ring 1. The inner wall of the first connecting cylinder 301 is provided with a first sliding groove 302, the inner wall of the first sliding groove 302 is slidably connected to a first sliding block 303, and the outer wall of the first sliding block 303 is rotatably connected to the second connecting cylinder 304.

[0026] The inner wall of the second connecting cylinder 304 is provided with a second sliding groove 7. The inner wall of the second sliding groove 7 is slidably connected with a second sliding block 8. The outer wall of the second sliding block 8 is rotatably connected with a third connecting cylinder 11. The outer wall of the third connecting cylinder 11 is threadedly connected with a third retaining ring 2. The splicing mechanism 4 includes a first splicing block 401. The first splicing block 401 on the first retaining ring 1 is connected by a first fixing screw 403 to realize the splicing between the first retaining ring 1 and the second retaining ring 404. The outer wall of the first splicing block 401 is fixedly connected with the first retaining ring 1. A screw hole 402 is installed on the inner wall of the splicing block 401. The inner wall of the screw hole 402 is threadedly connected with the first fixing screw 403. The outer wall of the first fixing screw 403 is threadedly connected with the second retaining ring 404.

[0027] The first fixing screw 403 and the second fixing screw 10 pass through the first splicing block 6 and the second retaining ring 404 and the second retaining ring 404 and the second splicing block 9, so that the first retaining ring 1, the second retaining ring 404 and the third retaining ring 2 form an integral spiral retaining ring, which plays a buffering effect when the first retaining ring 1, the second retaining ring 404 and the third retaining ring 2 are extruded and deformed. In addition, the third connecting cylinder 11 applies a downward force to drive the second sliding block 8 to slide on the second sliding groove 7 inside the second connecting cylinder 304, which can also play a buffering effect, improve the contact force change between the upper third connecting cylinder 11 and the third retaining ring 2, and achieve a wear-resistant effect.

[0028] Working principle:

[0029] Assembly stage

[0030] Insert the first splicing block 6 on the first retaining ring 1 into the inside of the second retaining ring 404, and turn the first fixing screw 403 to pass through between the first splicing block 6 and the second retaining ring 404, so that the second retaining ring 404 and the first retaining ring 1 are fixed. Similarly, insert the second splicing block 9 on the second retaining ring 404 into the inside of the third retaining ring 2, and turn the second fixing screw 10 to pass through the second retaining ring 404 and the second splicing block 9 to fix the third retaining ring 2 and the second retaining ring 404. Then turn the first connecting ring 301, the second connecting cylinder 304 and the third connecting cylinder 11 in sequence, so that the outer wall of the first connecting ring 301 is threadedly fixed with the first retaining ring 1, the outer wall of the second connecting cylinder 304 is threadedly fixed with the second retaining ring 404, and the third connecting cylinder 11 is threadedly fixed with the third retaining ring 2 to realize the overall installation.

[0031] Usage stage

[0032] Install the third retaining ring 2 in the appropriate position. At this time, the third retaining ring 2 contacts the third connecting cylinder 11 and the diaphragm spring. During use, the diaphragm spring directly contacts the third retaining ring 2 and the third connecting cylinder 11, improving the density formed by the third connecting cylinder 11 and the third retaining ring 2, extending the service life of the retaining ring. There is a certain gap between the first retaining ring 1, the second retaining ring 404, and the third retaining ring 2, and the whole has an elastic effect. When the third retaining ring 2 is under frictional pressure, the third connecting cylinder 11 applies a downward force to drive the second slider 8 to slide on the second chute 7 inside the second connecting cylinder 304, and the first slider 303 on the second connecting cylinder 304 also moves on the first chute 302 inside the first connecting cylinder 301, playing a buffering effect when the first retaining ring 1, the second retaining ring 404, and the third retaining ring 2 are squeezed and deformed, forming three - stage buffering and reducing the long - term friction between the third retaining ring 2 and the third connecting cylinder 11.

The outer wall of the second fixing screw 10 is threadedly connected to the third retaining ring 2.

[0034] Working principle:

[0035] The second fixing screw 10 passes through the second splicing block 9 and the third retaining ring 2 to assemble the third retaining ring 2 and the second retaining ring 404. And according to the wear condition between the third retaining ring 2 and the second retaining ring 404, their positions can be mutually replaced, improving the overall service life.
