After the first clamping jaw 11 passes through the first clamping hole 31, the passed portion is bent to fixedly clamp the main elastic member 4, and then the driven disc 2 is fixed.

[0066] The novel torque damper designed in this application uses the first clamping jaw 11 on the cover plate 1 to abut against the main elastic member 4 to fix the driven disc 2, and has the following beneficial effects:

[0067] 1. The use of fasteners such as rivets is reduced, the assembly process is reduced, and the assembly cost is lowered;

[0068] 2. One cover plate 1 is reduced, thus reducing the number of parts and lowering the cost;

[0069] 3. Since one cover plate 1 is reduced, the overall structure requires less space axially and is more compact.

[0070] The above is Embodiment 1 of a novel torque damper provided by this application. The following is Embodiment 2 of a novel torque damper provided by this application. For details, please refer to Figures 1 to 7 。

Compared with directly setting the first vibration damping spring 2321 and the second vibration damping spring 2322, the setting of the spring seats 2323 can reduce or even avoid abnormal noises and wear caused by metal contact between the first vibration damping spring 2321 / the second vibration damping spring 2322 and the vibration damping disc 211.

[0081] Further, the surface sheet assembly 212 includes a friction sheet 2121 and a connecting sheet 2122.

[0083] The connecting sheet 2122 is riveted to the vibration damping disc 211.

[0087] The disk hub 24 is installed above the first sub-compressing member 22.

[0088] At least two third claws 251 are provided along the circumferential direction of the second sub-compressing member 25, specifically four third claws 251; third card holes 292 corresponding to the third claws 251 one by one are provided on the clamping disk 29; the first sub-elastic member 27 is installed on the second sub-compressing member 25 and is located between the third claws 251; the large end of the first sub-elastic member 27 faces the second sub-compressing member 25 and is installed between the third claws 251 of the second sub-compressing member 25. After the third claws 251 of the second sub-compressing member 25 are aligned with the third card holes 292 of the clamping disk 29, they are buckled into the clamping disk 29.

Specifically, after the process holes of the clamping disk 29, the process holes of the damping disk 211, and the process holes of the damping disk 231 are aligned, they are riveted to the damping disk 211 through a plurality of limit pins 210 (for example, four).

[0091] Further, the first sub-compressing member 22, the second sub-compressing member 25, and the third sub-compressing member 26 are all nylon compression sheets, which have a lower weight and better lightweight effect compared to metals.

[0092] Further, the main elastic member 4, the first sub-elastic member 27, and the second sub-elastic member 28 are all disc springs.

[0093] Compared with the traditional torque damper, the novel torque damper designed in the present application can reduce the number of parts by tightly fitting the first claw 11 of the cover plate 1 with the main elastic member 4, and can effectively reduce the weight of the product by combining the hollow rivet 2123 design of the face sheet assembly 212 and the nylon pressing sheet design, thereby achieving the purpose of lightweighting the product. Moreover, it can simplify the assembly and disassembly processes and reduce production costs.
