Track wheel and elastic body for such a track wheel

Abstract

The present invention relates to a multi-part track wheel with a wheel tyre, with a wheel rim and with at least two elastic bodies arranged between the wheel tyre and the wheel rim, via which the wheel tyre is supported spring elastically on the wheel rim and which are arranged distributed in the circumferential direction around the rotary axis of the track wheel, wherein the elastic bodies are clamped between an inner circumferential surface of the wheel tyre and an outer circumferential surface of the wheel rim and in this case abut with their outer side assigned to the wheel tyre on the inner circumferential surface of the wheel tyre and with their inner side assigned to the wheel rim on the outer circumferential surface of the wheel rim and an elastic body for use in a track wheel. The track wheel according to the invention designed according to the one-ring concept provides an optimised low spring constant and the elastic body as an essential component for the spring properties allows the manufacture of a one-ring track wheel with optimised usage properties. This is achieved in that the elastic bodies are locked against a movement in the circumferential direction by forming elements provided in each case on the inner circumferential surface of the wheel tyre and/or on the outer circumferential surface of the wheel rim.
