Abstract
A limited slip differential is disclosed which includes a first rotary element, a second rotary element, and a hydraulic unit including a plurality of reciprocal pistons in slidable engagement with an internal cam surface of the first rotary element. The hydraulic unit includes an accumulator and a fluid passage in fluid communication with the accumulator and each of pressure chambers defined by the pistons. A variable flow restrictor is provided between the accumulator and each of the pressure chambers to automatically regulate a differential slip limiting torque in response to variation of rotational speed differential between driving wheels.
