Abstract

A wheel support for trailer axles is provided, and includes tapered-roller bearings disposed on an axle neck; it also includes a hub that is rotatably mounted on the bearings. The hub serves for the mounting of a brake drum and a wheel, with a thrust washer being disposed between the axle neck and the inner tapered-roller bearing, and with an axle nut being screwed onto an outer thread of the axle neck outwardly of the outer tapered-roller bearing. To provide a partial preassembly and to simplify the mounting and removal of the wheel support, the thrust washer is secured in the hub via a first snap ring, the axle nut is provided with a collar that extends to the inner wall of the hub, and the axle nut is secured at its collar in the hub via a second snap ring.
