The invention relates to a braceable emergency operation (1) for a motor vehicle wheel, comprising ring segment-shaped sub-elements which are each either hinged to one another or can be braced to one another via a clamping system. In order to provide the possibility that the penetration of dirt can be prevented regardless of the air pressure in the tyres, the cross-section of the sub-elements are to be formed in a T-shape on the tyre side, wherein the crossbeam (5) of the T-shaped design serves as a running surface for the tyres in the event of a tyre failure, and the cross-section of the sub-elements is formed on the rim side in an approximate T-shape with two lateral end points, wherein the crossbeam of the T-shaped design serves for assembly on the rim base and rests on same in the assembled state, wherein the tyre-side T-shaped design and the rim-side T-shaped design are connected to one another, in particular via a radially running web, wherein the lateral end points of the crossbeam of the rim-side T-shaped design are to be shifted on top of one another against a return force, via at least one sub-region that is provided between the two end points of the crossbeam and elastically developed. |
