ABSTRACT:
A differential includes a planet gear through which two shafts coupled to laterally spaced road wheels of a motor vehicle are interconnected. The planet gear has a rotatable shaft with a brake mechanism coupled thereto. A braking force produced by the brake mechanism is transmitted through the differential to the road wheels depending on the rotational speeds of the road wheels. The brake mechanism may include either a turbine for producing a resistive force upon rotation thereof or a hydraulic damper comprising a hydraulic pump and a variable restriction.
