Abstract
The invention relates to a resilient, multi-component wheel for rail vehicles, comprising a rim (2) and hub (11) as well as an elastic element (6, 8) removably inserted between said rim and hub. Said elastic element (6, 8) is configured as a concentric, separate part consisting of a central disk (7), two larger outer disks (5, 9) and two elastomer rings (6, 8) positioned between said disks. Said elastomer rings (6, 8) are made of a plastic material or rubber, can have different shapes depending on the desired type of compressive stress or shear stress and are connected to the disks (5, 9) in a non-positive manner.
