ABSTRACT:
A two-speed differential adapted for use in motor vehicle driveline applications. The two-speed differential is capable of selectively transferring power to either a first drive mechanism for establishing a first drive speed ratio or a second drive mechanism for establishing a second drive speed ratio. The selected drive mechanism then transmits power to an output mechanism for subsequent transmission to the driving axles of the motor vehicle while permitting speed differentiation therebetween. In one aspect of the present invention, the first drive mechanism provides a "direct drive" speed ratio and the second drive mechanism provides an "overdrive" speed ratio. In another aspect of the present invention, the first drive mechanism provides a "direct drive" speed ratio and the second drive mechanism provides an "underdrive" speed ratio.
