Abstract
An axle shaft and pump drive mechanism (12) for a vehicle (10) includes a continuously variable transmission unit (24), an axle shaft (20), a pump (22), and a coupling device (34,78) for connecting the transmission unit (24) to the axle shaft (20) or to the pump (22) and operating them individually through an infinitely variable speed ratio range. When the vehicle, such as a backhoe loader, is not being propelled, the continuously variable transmission unit (24) can be used to drive the implement pump (22) which can then be of the fixed displacement type for improved effectiveness.
