1. The present invention relates to the technical field of automobile clutches, in particular to a driven disc assembly.

Background technique:

2. The inner ring of the car is another part of the clutch, which transmits the torque of the engine to the transmission through friction conversion, reduces the vibration and impact of the drive train, and completes the tasks of "disengagement" and "combination". The inner ring of the automobile clutch is an essential consumable part of the manual transmission step-change car. When in use, the driven disc assembly transfers the torque of the engine to the transmission through friction conversion. At present, most clutch driven disc assemblies on the market use Friction plates made of organic friction materials, when the car starts with too much energy or overloads, it is easy to cause the friction plates to burn out; secondly, it is affected by the material and manufacture of the friction plates.

3. In the prior art, the strength of the inner ring of the clutch is relatively low, so that when the clutch is hit by a collision, the inner ring is prone to collision damage, thereby shortening the service life; on the other hand, the wear resistance of the existing clutch inner ring is poor, It is subject to friction for a long time during use, which is prone to friction damage and shortens the service life.

4. Chinese patent cn201811374803.8 discloses "a clutch driven disc assembly with a reinforced protective device", which includes a large steel plate of the clutch driven disc, a clamping disc and a clutch reinforcement plate. The clutch reinforcement plate is set close to the engine flywheel The large steel plate of the clutch driven plate assembly on one side is fixed together with the large steel plate of the clutch driven plate assembly and the clamping plate through rivets.

Based on the ordinary clutch driven plate assembly, this technology installs a clutch reinforcing plate on the side close to the engine flywheel, and uses riveting to fix the large steel plate of the clutch driven plate assembly and the clutch reinforcing plate together. Strengthen the axial rigidity and strength of the clutch driven disc assembly, reduce the failure rate caused by stiffness and strength and improve the wear resistance of the clutch driven disc assembly, but the traditional split wave plate is still used when using, which will cause The heat dissipation effect of the driven plate assembly is not good, which leads to the burning of the friction plate.\
