Abstract

A wheel bearing assembly for trucks includes a brake element and a wheel adapter defining a rotating component, an axle element defining a stationary component, and a multi-row, preferably double-row, bearing unit. The bearing unit has a first bearing ring, a second bearing ring and a plurality of rolling elements disposed between the first and the second bearing ring. The first bearing ring is connected to a drive shaft, the second bearing ring is connected to the axle element and the wheel adapter is configured to connect the first bearing ring to the wheel and the brake element. A shield is disposed between the brake element and the first bearing ring and/or disposed between the brake element and the axle element and is configured to shield a space defined by the first bearing ring, the wheel adapter and the brake element from entry of particles and/or water.
