Method for increasing torque transmission and endurance limit of joining area at brake disk pot of connection brake disk, involves smoothing joining area and plastically deforming roughness points on joining area by polishing roll

摘要

The method involves providing a connection brake disk including a brake disk pot (1) and a friction ring, which are connected with each other using a micro form-fit connection. A joining area (2) is smoothed on the brake disk pot, and roughness points are plastically deformed on the joining area by a polishing roll (4) such that a hardened, fine-grained edge layer is formed, where a thickness of a material carrier part is increased by the edge layer. The joining area is hardened upto a depth of 10 micro meters. An independent claim is also included for a device for increasing torque transmission and endurance limit of a joining area at a brake disk pot of a connection brake disk.
