Abstract: The final drive is the main vehicle of transmission in reducing speed and increase torque of the main components，its performance has the direct influence to the entire vehicle quality, carries on the omni-directional examination on the production line through the experimental system of final drive to be able effectively to guarantee the product quality. This article introduced the mechanism design and the Electrical system design. The system may realize to three types of final drive overall performance examinations, and evaluate the production performance according to the technique parameters beforehand. Machine parts include platform system, transmission system and jig system. Platform system may realize to strut and localization of electromotor. The transmission system may realize to translate power and connect torque tachometer to overall system. The jig system may realize to locate and clamp the final drive and guarantee the final drive input axis can form the stable connection with the transmission system.
