ABSTRACT:
A wheel bearing, in particular for toy vehicles, which are usually subjected to strong overloads, is characterized in that, in the vicinity of each end, the wheel axle (10, not shown in FIG. 2) has both a bearing face (14, 15) with a relatively small radius of curvature and a bearing face (12, 13) with a relatively large radius of curvature substantially corresponding to the radius of the axle. The bearings with the small radius of curvature (14, 15) are elastically resilient, the bearing faces with the relatively small radius of curvature being provided in bearing plates (2, 3) which are connected with a vehicle portion (1) via elastic connecting members (4, 5). When the toy vehicle is overloaded, the axle is supported in the large bearings (12, 13) so that the small bearings (14, 15), having a very small friction under normal operating conditions, are not damaged.
