Abstract: A road simulation test system and method for testing torsional strain input to an axle assembly having an input shaft and a suspension system, including a torque input module configured to apply rotary torque to the axle assembly. The torque input module includes a rotary actuator, a torsional load cell, a drive shaft connection portion, and a controller in communication with the rotary actuator and the torsional load cell, wherein upon receipt of an instruction from the controller, the rotary actuator is configured to rotate the input shaft to apply the rotary torque to the axle assembly, and as the rotary actuator rotates the input shaft, a signal indicative of a torsional load is communicated by the torsional load cell to the controller to monitor the rotary torque applied to the axle assembly.

Abstract: A method and apparatus is provided for the attachment of a throttle shaft to a throttle body. A throttle shaft, a spring, and a cap retainer, are temporarily assembled as a throttle shaft subassembly. A set of locking members extend from the cap retainer to engage a set of locking surfaces adjacent the throttle shaft to retain the spring in tension. The cap retainer fits onto a boss extending from the throttle body and is lockable thereto by a set of fingers which are received into engagement recesses located on the boss. As the shaft subassembly is guided into the throttle body, the cap retainer is rotated by the engagement surfaces and the locking members are disengaged from the locking surfaces to at least partially unload the spring to mount the shaft.
