Emergency operation

Abstract

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 oneanother 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 areto 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.

Description

technical field [0001] The present invention relates to a clampable (verspannbar) for a motor vehicle wheel consisting of a rim and a pneumatic tire which respectively has tire beads on both sides and is arranged on the rim with the two tire beads emergency insert (Notlaufeinsatz) with at least two, especially three, ring-segment-shaped subelements (Teilelement), wherein the mutually adjacent subelements are correspondingly or hingedly connected to each other or via a clamping system ( Spannsystem) can be clamped to each other. Background technique [0002] Such systems are known from practice in various special designs. It is disadvantageous here that when the air pressure in the interior of the tire is reduced, as it is, for example, in the case of off-road driving (Geländefahrt) and sandy driving (Sandfahrt), in order to increase the bearing surface (Aufstandfläche, sometimes also called vehicle footprint) and are often used for better traction, the tire bead is no long...

Problems solved by technology

It is disadvantageous here that when the air pressure in the interior of the tire is reduced, as it is, for example, in the case of off-road driving (Geländefahrt) and sandy driving (Sandfahrt), in order to increase the bearing surface (Aufstandfläche, sometimes also called vehicle footprint) and are often used for better traction, the bead is no longer reliably held at the rim shoulder, so that sand and / or dirt can penetrate

This sooner or later however is bound to lead to damage
