WHEEL HUB AND BRAKE DISC ARRANGEMENT FOR HEAVY VEHICLES

摘要

A wheel hub and brake disc device for a vehicle wheel, comprising a wheel hub journalled on an axle and having outer splines meshing with inner splines on a brake disc supported on the wheel hub. The disc is prevented from displacement in one axial direction by means of a broken retainer ring (14), which is located in a peripheral groove. One end portion (17) of the ring is bent radially inwards to form a lock pin, which protrudes into a spline groove to prevent the ring from rotation.
