ABSTRACT:
The invention relates to a vehicle wheel with internally located emergency wheel, which is composed of a plurality of segments, preferably four segments. The segments have a substantially double T-shaped cross-section. Each segment is clamped in the well-base channel of the wheel rim by means of two clamp screws. In order to facilitate assembly of the emergency wheel, a clear space kept totally free from other installations is provided between the segments and the tire beads supported at the wheel rim. This space permits easy alignability and mobility of the segment pieces in the circumferential direction. Axial grooves on the radial inner sides of the segments, at an interval corresponding approximately to the diameter of the clamp screws, permits the circumferential alignment of the segments during the assembly by means of a screwdriver or the like. The segments are fastened with two screws each. All of the screw are distributed uniformly on the circumference in the fully assembled emergency wheel, thus the displacement distances of the segments in the circumferential direction for proper alignment with a set of holes in the rim is relatively small. A relieved countersunk section at the screw threaded bores permits a reliable mechanical retention of a sealing ring and the screws, and a comfortable and damage-free introduction of same into the sealing position before the assembly of the segments in the tire or the rim.
