Description

Technical Field

[0001] The utility model relates to the technical field of automobile clutches, in particular to an automobile clutch friction plate. Background Art

[0002] The clutch plate is the medium that transmits the engine power to the gearbox. The working principle of the clutch is to compress the clutch friction plate through the pressure plate to transmit the engine power to the gearbox. The clutch friction plate is installed between the flywheel and the pressure plate, and transmits the engine power to the gearbox through the key shaft. The clutch friction plate is a composite material with friction as its main function and structural performance requirements.

[0003] The existing friction plate is mainly composed of an annular friction plate and a middle mounting structure. When the input shaft of the gearbox passes through the middle mounting structure, the friction plate can drive the input shaft to rotate. However, the existing friction plate and the middle mounting structure are fixedly connected by multiple bolts. When the friction plate is severely worn and needs to be replaced, the disassembly process is relatively troublesome. Secondly, since the existing friction plate is annular in shape, the contact area between the friction plate and the flywheel is limited, so the friction force is limited when the friction plate and the flywheel just contact. Therefore, the utility model proposes an automobile clutch friction plate. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 5 As shown, it relates to a car clutch friction plate, including a friction plate 1 and a connecting plate 2, a shaft sleeve 3 is fixedly connected to the middle of the connecting plate 2, through holes 4 are opened on both sides of the friction plate 1 and the connecting plate 2, a through rod 5 is passed through the through holes 4 of the friction plate 1 and the connecting plate 2, an end of the through rod 5 close to the friction plate 1 is fixedly connected to an end plate 8, a side wall of the other end of the through rod 5 is provided with a clamping assembly 6, a clamping sleeve assembly 7 for fixing the through rod 5 is provided on the side of the connecting plate 2 away from the friction plate 1, and a plurality of tightening assemblies 10 are provided on the side of the connecting plate 2 close to the friction plate 1.

[0024] The inner wall of the shaft sleeve 3 is provided with a spline groove.

[0025] The interior of the spline groove is used to insert the input shaft of the gearbox, so that the input shaft of the gearbox can be driven to rotate through the shaft sleeve 3.

[0026] The clamping assembly 6 includes a first groove 61 opened on the side wall of the penetration rod 5, the inner wall of the first groove 61 is fixedly connected with a first spring 62, the other end of the first spring 62 is fixedly connected with a locking tooth 63, and the sleeve assembly 7 includes a sleeve 71 sleeved on the surface of the penetration rod 5, and the side wall of the sleeve 71 is provided with a locking hole 72 for locking the locking tooth 63.

[0027] When the sleeve 71 is sleeved on the surface of the penetrating rod 5, the first spring 62 pushes the latching teeth 63 into the latching holes 72, thereby fixing the sleeve 71 on the surface of the penetrating rod 5. Therefore, under the extrusion and limiting action of the sleeve 71 and the end plate 8, the connecting disc 2 is fixedly connected to the friction disc 1. When the friction disc 1 needs to be disassembled and replaced, the latching teeth 63 are squeezed back into the first groove 61, and the latching teeth 63 are separated from the latching holes 72, so that the sleeve 71 can be disassembled from the surface of the penetrating rod 5, and then the penetrating rod 5 is pulled out of the through hole 4, that is, the friction disc 1 is disassembled.

[0028] A recessed groove 9 is formed near the through hole 4 of the friction disc 1 , and the end plate 8 is located inside the recessed groove 9 .

[0029] After the end plate 8 is located inside the sink groove 9, it can ensure that the surface of the friction disc 1 is flat, so that the friction disc 1 can be in full contact with the flywheel.

[0030] The pressing assembly 10 includes a second groove 101 formed on the surface of the connecting plate 2 , and a second spring 102 is fixedly connected to the inner wall of the second groove 101 .

[0031] The second spring 102 can play a role in spreading the connection plate 2 and the friction plate 1 , and the through rod 5 , the end plate 8 and the sleeve 71 provide fixing strength to the connection plate 2 and the friction plate 1 .

[0032] A plurality of strip grooves 11 are provided on the surface of the friction disc 1 close to the connecting disc 2. The strip grooves 11 increase the contact area between the friction disc 1 and the air, and can play a certain heat dissipation role.

[0033] A plurality of heat dissipation holes 12 are provided on the side of the friction disc 1. The heat dissipation holes 12 can further increase the heat dissipation effect of the friction disc 1.

[0034] Working principle: When assembling the friction plate, align the through hole 4 on the friction plate 1 with the through hole 4 on the connecting plate 2, then insert the penetration rod 5 into the through hole 4 from one side of the friction plate 1, and make the end plate 8 be located in the sink groove 9, then put the sleeve 71 on the surface of the penetration rod 5, and the latch tooth 63 will be squeezed into the first groove 61. When the latch hole 72 on the side wall of the sleeve 71 is close to the latch tooth 63, the latch tooth 63 is ejected by the first spring 62. After the latch tooth 63 is latched into the latch hole 72, the fixed connection between the connecting plate 2 and the friction plate 1 is realized.
