[0028] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0029] Reference below Figure 1-Figure 4 A clutch driven disc 10 for a vehicle according to an embodiment of the present application is described, wherein the clutch driven disc 10 includes a first friction plate 11, a second friction plate 12 and a corrugated plate assembly 13, wherein the first friction plate 11 and the second friction plate 12 are spaced apart from each other and the first friction plate 11 and the second friction plate 12 are respectively suitable for cooperating with a flywheel and a pressure plate, wherein the corrugated plate assembly 13 is arranged between the first friction plate 11 and the second friction plate 12, and the corrugated plate assembly 13 is formed by stacking corrugated plates 131 stacked in a thickness direction, wherein the corrugated plates 131 are constructed of more than two, and two adjacent corrugated plates 131 are at least partially spaced apart to form a deformation space, wherein the corrugated plate assembly 13 is suitable for compressing the deformation space when the first friction plate 11 is in contact with the flywheel.

[0030] At present, the clutch can connect or cut off the power transmission from the engine to the drive shaft, transmit the power of the engine to the gearbox, keep the engine running while the vehicle remains stationary, cut off the torque transmission when gear selection and shifting are required, and reduce the vibration caused by the engine rotation. The clutch driven plate is an important component on the clutch. The corrugated plate in the existing driven plate is thicker, the forming height is higher, the initial force is larger, and the height and force value decay greatly during use, resulting in a large impact when engaging with the clutch, affecting the feel of the clutch pedal.

[0031] like Figure 1 and Figure 2As shown, specifically, the clutch driven disc 10 includes a friction plate and a corrugated plate assembly 13. The friction plate can be constructed as a first friction plate 11 and a second friction plate 12 spaced apart in the thickness direction, and the first friction plate 11 and the second friction plate 12 can cooperate with the flywheel and the pressure plate respectively. The corrugated plate assembly 13 can be arranged between the first friction plate 11 and the second friction plate 12. The corrugated plate assembly 13 can be formed by stacking a plurality of corrugated plates 131, and a plurality refers to more than two. The plurality of corrugated plates 131 can be stacked in sequence in the thickness direction. Since the distance between the first friction plate 11 and the second friction plate 12 is fixed, compared with the prior art, by arranging a plurality of corrugated plates 131, the thickness of a single corrugated plate 131 can be effectively reduced, so that the force value of the corrugated plate 131 is smaller, the rigidity of the corrugated plate 131 is small, and the force required for the deformation of each corrugated plate 131 is small, so that the clutch driven wheel can be smoother when engaging and separating with the flywheel.

[0032] Furthermore, at least part of the space between two adjacent corrugated plates 131 is set, and a deformation space is formed between the two adjacent corrugated plates 131. When the first friction plate 11 is in contact with the flywheel, the two adjacent corrugated plates 131 can be compressed toward the deformation space, thereby reducing the stiffness of the corrugated plate assembly 13, making the corrugated plate assembly 13 softer, and the force value and height of the corrugated plate assembly 13 are not easy to attenuate, thereby reducing the impact on the clutch operation.

[0033] In short, the clutch driven disc 10 of the embodiment of the present application has a corrugated plate assembly 13, and the corrugated plate assembly 13 can be composed of multiple corrugated plates 131 stacked in sequence in the thickness direction, and a deformation space is formed between two adjacent corrugated plates 131. When the clutch driven disc 10 is in contact with the flywheel, the corrugated plate assembly 13 can compress the deformation space, and the multiple corrugated plates 131 can be deformed toward the deformation space. Compared with the prior art, the thickness of each corrugated plate 131 is small, which reduces the stiffness of the corrugated plate assembly 13, making the connection and separation between the clutch driven disc 10 and the flywheel smoother.

[0034] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, each corrugated sheet 131 includes a first extension segment 1311 and a second extension segment 1312, the second extension segment 1312 can be connected to the first extension segment 1311, and the second extension segment 1312 can be located on at least one side of the first extension segment 1311 in the circumferential direction. In a specific embodiment, the second extension segment 1312 can be located on both sides of the first extension segment 1311 in the circumferential direction.

[0035] Among them, the first extension sections 1311 of two adjacent corrugated plates 131 can be arranged opposite to each other in the thickness direction, and the second extension sections 1312 of two adjacent corrugated plates 131 can also be arranged opposite to each other in the thickness direction, and the first extension sections 1311 of two adjacent corrugated plates 131 are recessed in directions away from each other to form a part of the deformable space, and the second extension sections 1312 of two adjacent corrugated plates 131 are recessed in directions away from each other to form another part of the deformable space. When the first friction plate 11 is in contact with the flywheel, the two adjacent corrugated plates 131 can be compressed toward the deformation space, thereby reducing the stiffness of the corrugated plate assembly 13 and reducing the impact on the clutch operation.

[0036] Furthermore, a protrusion 1313 is formed at the connection between the first extension section 1311 and the second extension section 1312, and the protrusions 1313 of two adjacent corrugated sheets 131 can abut against each other in the thickness direction, so that parts of two adjacent corrugated sheets 131 can fit together and ensure that deformation space can be formed on both sides of the protrusion 1313 in the circumferential direction.

[0037] In some embodiments of the present application, the corrugated sheet assembly 13 can be constructed as a first corrugated sheet and a second corrugated sheet. The first corrugated sheet and the second corrugated sheet can be arranged in sequence in the thickness direction, and the size of the first corrugated sheet in the thickness direction is L1, and the size of the second corrugated sheet in the thickness direction is L2. The size of the first corrugated sheet in the thickness direction can meet the following conditions: 0.3mm≤L1≤0.4mm, and the size of the second corrugated sheet in the thickness direction can meet the following conditions: 0.3mm≤L2≤0.4mm. By setting the size of the first corrugated sheet in the thickness direction and the size of the second corrugated sheet in the thickness direction within the above conditions, it can be ensured that the thickness of the first corrugated sheet and the thickness of the second corrugated sheet are smaller than the thickness in the prior art, so that the force value of the corrugated sheet 131 is smaller, the rigidity of the corrugated sheet 131 is small, and the force required for the deformation of each corrugated sheet 131 is small, so that the clutch driven wheel is smoother when it is combined with and separated from the flywheel. In a specific embodiment, the dimension of the first corrugated sheet in the thickness direction and the dimension of the second corrugated sheet in the thickness direction can satisfy: L1=L2. By setting the dimension of the first corrugated sheet in the thickness direction and the dimension of the second corrugated sheet in the thickness direction to the same dimension, the processing of the corrugated sheet 131 can be facilitated.

[0038] like Figure 3As shown, in some embodiments of the present application, each corrugated sheet 131 is formed with a limiting hole 1314 that is set through in the thickness direction, and the limiting hole 1314 of each corrugated sheet 131 is set correspondingly in the thickness direction, and the clutch driven plate 10 may also include a first fastener, which may be sequentially passed through the limiting holes 1314 of multiple corrugated sheets 131, and the first fastener may limit the multiple corrugated sheets 131 in the thickness direction, thereby achieving the limiting and fixing between the multiple corrugated sheets 131. In a specific embodiment, the first fastener may be configured as a rivet, and the multiple corrugated sheets 131 may be riveted together.

[0039] like Figure 1 As shown, in some embodiments of the present application, the clutch driven plate 10 also has an inner ring 14, and the corrugated plate 131 can be constructed as a plurality of circumferentially spaced plates, and the first friction plate 11 and the second friction plate 12 are bonded to the inner ring 14 and at least one of the corrugated plate assembly 13. Specifically, each corrugated plate 131 also includes a connecting plate 1315, and the connecting plate 1315 can be respectively connected to the first extension section 1311 and the second extension section 1312, and at least a portion of the connecting plate 1315 can extend in a direction away from the first extension section 1311, and the free end of the connecting plate 1315 can be connected to the inner ring 14, so as to fix the corrugated plate assembly 13 on the inner ring 14.

[0040] Furthermore, if Figure 3 As shown, a first mounting hole 1316 is formed on the connecting plate 1315 and is arranged to penetrate in the thickness direction, and a second mounting hole is formed on the inner ring 14 and is arranged to penetrate in the thickness direction and corresponds to the first mounting hole 1316. The clutch driven plate 10 also includes a second fastener, and the second fastener can be sequentially passed through the second mounting hole and the first mounting hole 1316 to fix the connecting plate 1315 on the inner ring 14, and then fix the corrugated plate assembly 13 on the inner ring 14. In a specific embodiment, the second fastener can be constructed as a rivet, and the connecting plate 1315 and the inner ring 14 can be matched by riveting.

When the clutch driven disc 10 is in contact with the flywheel, the corrugated plate assembly 13 can compress the deformation space, and the plurality of corrugated plates 131 can be deformed toward the deformation space. Compared with the prior art, the thickness of each corrugated plate 131 is small, which reduces the stiffness of the corrugated plate assembly 13 and makes the connection and separation between the clutch driven disc 10 and the flywheel smoother.
