Torque transmission device for drive train of vehicle, has spring element subjected to wear of outside boundary region during relative motion between primary side and secondary side at supporting surface

摘要

The device (10) has a disk-like sealing spring element (60) supported with respect to a supporting surface (84). The supporting surface is formed on a secondary side (16) in a radial outer boundary region of the spring element. The spring element is subjected to wear of the outer boundary region during relative motion between a primary side (12) and the secondary side at the supporting surface. The wear leads to reduction of an outer diameter of the spring element, and the spring element remains supported at the supporting surface.
