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.
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, characterised 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, wherein a number of the elastic bodies have, on their outer side or inner side, at least one forming element, which interacts at least in the circumferential direction in a positive-locking manner with one of the forming elements present on the inner circumferential surface of the wheel tyre or the outer circumferential surface of the wheel rim.
(canceled)
An elastic body for use in a track wheel comprising a wheel tyre and a wheel rim and at least two elastic bodies, via which the wheel tyre is supported spring elastically on the wheel rim, wherein the elastic body has a block-shaped base form with end side front sides of which in each case one is assigned to one of the front sides of the track wheel, longitudinal sides extending laterally between the front sides, an outer side assigned to the wheel tyre, also extending between the front sides and meeting at its longitudinal edges with the longitudinal sides and an inner side opposed to the outer side, which is assigned to the wheel rim of the track wheel, characterised in that the elastic body is provided, on its outer side assigned to the wheel tyre, with a forming element, which is provided to interact with a correspondingly shaped forming part on the inner circumferential surface of the wheel tyre in a positive-locking manner.
