Abstract
A system for testing a power train assembly such as a transaxle of a vehicle has first and second gear units each having separate input members for receiving input torque from the power train assembly to be tested, a mounting member for supporting the power train assembly between the first and second gear units, a drive motor for supplying input torque to the power train assembly, and a dynamometer connected with the second gear unit. The drive motor is connected with the input member of the power train assembly by a driving shaft passing through the first gear unit. Preferably, the first and second gear units are connected by at least one interconnecting shaft extending under the power train assembly. With this arrangement, the test system is smaller in required space, smaller in inertia, capable of high speed testing, and readily applicable to different types of power train assemblies.
