Abstract
An automotive drive system is disclosed including a continuously variable drive system including input and output pulleys and a belt intercoupling the pulleys, a hydrodynamic device, a forward-reverse gear set, a reduction gear set and a differential assembly where the elements are mounted along two axes. The hydrodynamic device, forward-reverse gear set and the input pulley of the continuously variable drive system are mounted along the first axis. The output pulley, the reduction gear set and the differential assembly are mounted along the second axis which is coaxial with the longitudinal axis of the axle shafts. The reduction gear set includes both a high-speed and a high-torque gear train, and the high-torque gear train is an integral element of the final drive differential. The hydrodynamic device includes a lock-up clutch for direct drive through the hydrodynamic device at operating road speeds.
