Abstract
A test system uses the four square principle for loading front wheel drive units of automobiles under torque, and provides the necessary loads on the front wheel drive unit for adequate testing. The unit under test may be subjected to 'steering' loads; to torque; to axial loads; and to 'jounce' which simulates vertical loads on front wheel drives of automobiles caused by road irregularities, holes or other obstacles. The present device permits application of all of these loads into four separate front-wheel drive-steering units for efficient testing. The mechanical configuration insures the ability to precisely control the loads in the various modes of operation.
