ABSTRACT:
A wheel-mounting arrangement for trailer axles, including tapered-roller bearings that are disposed on an axle spindle, and a hub that is rotatably mounted on the axle spindle via these tapered-roller bearings. A brake drum and a wheel or TRILEX star can be secured to the hub, which comprises an inner hub and an outer hub that is fixedly secured to the inner hub. In order to provide the wheel-mounting arrangement with emergency operation characteristics, the axle spindle has a tapered configuration in the region between the tapered-roller bearings, and the inner hub has a corresponding, inwardly projecting, tapered configuration between these same roller bearings. The tapered portions of the axle spindle and the inner hub together form a friction or sliding bearing for emergency operation.
