Abstract
The present invention relates to a clutch actuation mechanism having a valve, a plurality of couplings in fluid communication with the valve, wherein one of the plurality of couplings is operable to distribute power between a primary set of wheels and a secondary set of wheels, and another of the plurality of couplings is operable to distribute power between each of the secondary set of wheels. The present invention also includes a drive shaft driven by a source of power, which is also connected to the secondary set of wheels, and a pressure supply device in fluid communication with the valve, wherein the valve directs fluid to the plurality of couplings, and when the valve directs fluid to the one of the plurality of couplings operable to distribute power between the primary set and secondary set of wheels, the drive shaft will transfer power to the secondary set of wheels.
