<p>The wheel bearing test system (10) comprises a wheel (20) and bearings (40) mounted on a multi-planar movable 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.</p> |
