The wheel bearing test system (10) comprises a wheel (20) and bearings (40) mounted on an axle mechanism in order to effect realistic testing of the bearings (40). The axle mechanism (30) comprises a mandrel assembly (30) which is attached to a T-shaped connecting member (50). An axial load application mechanism (60) is disposed substantially coaxially with the axle mechanism (30), and is attached to one leg (52) of the T-shaped connecting member (50). A pair of radial and moment load application mechanisms (72, 74) are attached to the top legs (54, 56) of the T-shaped connecting member (50) and disposed substantially orthogonally relative to the axle mechanism (30). A motor (12) is connected with a wheel attachment fixture (18), the attachment fixture (18) fixed to the wheel (20) in order to effect rotation thereof. Operation of the wheel bearing test system (10) imposes realistic axial, radial, and moment loading upon the bearings (40) in their intended operational environment.

A wheel bearing testing system, comprising motor means connected with a fixed support, a wheel connected with the motor means and rotatable by the motor means, multi-planar movable axle means upon which the wheel is mounted via wheel bearings, an axial load application mechanism disposed substantially coaxially with said axle means, a radial and moment load application mechanism, a multi-planar movable connecting member connecting together the axial load application mechanism, radial and moment load application mechanism, and multi-planar movable axle means, the axle means attached fixedly to the connecting member, load sensing devices associated with the load application mechanisms, and control means, so that activation of the respective load application mechanisms effects through the multi-planar movable axle means the selective imposition of multi-planar loading upon the bearings so that the bearings experience realistic operating conditions during rotation of the wheel by the motor means and when the wheel is at rest.
