Test apparatus comprises a wheel means including a hub and wheel web rotatably mounted on wheel bearings set in the wheel hub and mounted on a non-rotatable axle mechanism. The wheel means is rotatable by motor means. A load application mechanism including hydraulic load cylinders and load sensors effects selective imposition of radial, axial and moment loading upon the wheel web, wheel hub and wheel bearings so that the bearings experience operting conditions during rotation and at rest. Acoustic sensing means enable determination of the onset of bearing failure. Operation of test apparatus is preferably controlled by a computer.

Apparatus and method for testing wheels, bearings and lubricants

A multiple disc brake assembly having a plurality of interleaved rotor discs and stator discs which are cooperative with a stationary torque tube which has a carbon composite brake pad mounted on its reaction plate in such a manner to prohibit stress concentration due to relative thermal expansion between the non-similar materials of the torque tube and brake pad at the torque reaction points while providing a reaction mechanism to circumferential forces generated by brake friction.
