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.

Abstract translation: 本发明涉及一种具有内部定位的紧急轮的车轮，其由多个段组成，优选地为四个段。 这些段具有大致双T形横截面。 每个段通过两个夹紧螺钉夹在轮缘的井底通道中。 为了便于紧急车轮的组装，在节段和支撑在车轮轮辋处的轮胎胎圈之间提供了完全没有其他设备的清洁空间。 这种空间允许片段在圆周方向上易于对准和移动。 在段的径向内侧上的轴向凹槽以相当于夹紧螺钉的直径的间隔允许在组装期间通过螺丝刀等进行圆周对准。 分段用两个螺丝固定。 所有的螺钉均匀地分布在完全组装的应急轮的圆周上，因此沿圆周方向的段的位移距离用于与轮辋中的一组孔正确对准相对较小。 在螺纹孔处的缓冲沉孔部分允许密封环和螺钉的可靠的机械保持，以及在轮胎或轮辋之间的段的组装之前将其舒适且无损坏地引入密封位置。
