Abstract
The present invention relates to a multi-part rail wheel with a wheel tyre, a wheel body, an elastic body arranged between the wheel tyre and the wheel body and via which the wheel tyre is supported on the wheel body, and at least one clamping element attached to the wheel body from one end face, via which the elastic body is braced against the wheel body and the wheel tyre by clamping means acting on the wheel body, the wheel body consisting of a light metal material in the region where the clamping means act. The rail wheel guarantees secure bracing of the components with simple assembly and disassembly. This is achieved by at least one counter-bearing element being provided on the end face of the wheel body opposite the clamping element. The counter-bearing element consists of a material which has a higher strength than the wheel body material.
