Title: Brake disc for disc brakes on rail vehicles

Abstract: A brake disc for disc brakes on rail vehicles comprises an intermediate member connected to the inner peripheral surface of an annular element. The intermediate member is spaced radially from a hub and there are a pair of radially opposed annular grooves in the hub and intermediate member with blocks of resilient material in the opposed grooves. The blocks are pre-stressed and completely occupy the widths of the grooves. Heat inhibiting material is provided for inhibiting heat flow from the annular braking element to the resilient blocks.
