DRIVE AXLE SYSTEM HAVING A CLUTCHING DEVICE

摘要

A drive axle system for a vehicle drive train having a clutching device is provided. The drive axle system includes a first shaft, a first axle assembly, a second axle assembly, a first clutching device, a second clutching device, and an axle assembly housing. At least a portion of the first shaft, the second clutching device, and at least one of the first axle assembly and the second axle assembly are disposed in the axle assembly housing. The first axle assembly is drivingly engaged with the first shaft. The first clutching device divides one of a pair of output axles into first and second portions. The second clutching device selectively engages a driving gear of the second axle assembly with one of the first shaft and a portion of the first axle assembly.
