When the sleeve is fixed to the main shaft by the fixing screws, the sleeve is deformed and clamped on the main shaft under the action of the fixing screws, resulting in eccentric installation. When rotating, the friction disc has a large amount of jumping deformation and poor rotation stability.

[0005] The application (patent) number is: CN202322810413.3, an elastic brake disc brake system structure, whose elastic friction disc includes a slotted hub, a spring plate, a friction plate and a locking screw. The friction plate is cast on the outer circle of the spring plate, and the locking screw is arranged at a position close to the center of the slotted hub. The friction plate is fixedly connected to the slotted hub by the locking screw. It also has the above-mentioned technical problems. Summary of the invention
