DRIVELINE TEST BENCH FOR AUTOMOTIVE CHASSIS SYSTEM AND TEST METHOD USING THE SAME

摘要

A driveline test bench for an automotive chassis system and a test method using the same are provided to efficiently evaluate an engine rotation of a driveline of an automotive chassis system and an NVH(Noises Vibration Harshness) property with a low cost. A driveline test bench(100) for an automotive chassis system includes a sub frame(15), a rear axle(30), a propeller shaft(20), a drive shaft(40), and a shaker. The sub frame has the rear axle which supports the sub frame and is placed at a lower part of the sub frame. The propeller shaft is coupled with the rear axle by a universal joint. The drive shaft is connected to the rear axle in a direction crossing the propeller shaft. The shaker generates torque to the propeller shaft of the drive shaft while doing a straight reciprocating motion. And the shaker is connected to a front edge of the propeller shaft.
