ABSTRACT:
A limited slip differential comprises juxtaposed axle gears rotatably mounted in a carrier meshing with planet gears arranged in staggered pairs and also rotatably mounted in a carrier. A hydraulically actuated friction clutch is positioned between the carrier and floating ring gear, which is meshed to certain of the planet gears, to retard rotation of the planet gears in response to a rotational speed differential of the axle gears. Control means for automatically actuating the clutch comprises a plurality of pistons reciprocably mounted in one axle gear and a cam surface attached to the other axle gear for pressurizing, in response to a rotational speed differential of the axle gears, the actuating chambers of the clutch.
