[0008] Furthermore, a variable diameter connection portion is provided between the pressure plate body and the lower convex ring portion, which increases the contact area between the pressure plate body and the lower convex ring portion and improves the connection strength. The whole can be formed by a stretching process, with high production efficiency, low cost and stable quality.

[0009] Furthermore, the reducing connecting part is connected to the lower extending part, and the ear part and the reducing connecting part are connected into a body. The reducing connecting part is supported by the ear part, so that the reducing connecting part is not easily deformed, thereby improving the overall structural strength.

[0010] Furthermore, a reinforcement block is provided between the lower extension portion and the variable diameter connection portion, thereby increasing the contact area between the lower extension portion and the variable diameter connection portion and improving the connection strength between the two.

[0011] Furthermore, the bolt mounting hole is stepped, and after the bolt is mounted, the end of the bolt is located in the bolt mounting hole without being exposed, and is not easily damaged by external direct impact.

[0013] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0014] 1. The pressure plate body presses the outer ring of the bearing through the lower convex ring, and the pressing force is more effective and reliable, preventing the bearing from freely escaping from the bearing chamber and improving the installation stability of the bearing.

[0015] 2. The setting of the lower extension portion increases the depth of the bolt installation hole, thereby increasing the contact area between the bolt and the bolt installation hole and improving the fastening effect of the bolt.

[0016] 3. The lower extension part is connected to the reinforcement block and the reinforcement ring at the same time to achieve radial reinforcement of the pressure plate body, thereby improving the structural strength of the pressure plate body, making it more resistant to pressure and collision, not easy to deform, and having a long service life.
