A limited slip differential is disclosed which includes a first rotary element, a second rotary element, and hydraulic means including a plurality of reciprocal pistons in slidable engagement with internal cam surface means of the first rotary element. The hydraulic means include an accumulator and fluid passage means in fluid communication with the accumulator and each of pressure chambers defined by the pistons. A pressure relief valve is provided in the accumulator chamber to prevent excessive increase in hydraulic fluid pressure in the hydraulic means.

Rotational speed differential responsive type torque transmitting

A torque transmitting assembly comprises a first rotary element including internal cam surfaces, a second rotary element disposed in the first rotary element, the second rotary element including a rotor containing a plurality of radially outwardly opening pressure chambers facing the cam surfaces, and a hydraulic mechanism for transmitting a ratio of the input torque from one of the first rotary element and the second rotary element to the other in response to rotation speed of the second rotary element and also to differential rotation occurring between the first rotary element and the second rotary element. The hydraulic mechanism is rotatable with the second rotary element and includes pistons in the pressure chambers in engagement with the cam surfaces and reciprocable in response to the differential rotation, passages in fluid communication with the pressure chambers through which hydraulic fluid discharged from each of the pressure chambers on the discharge stroke of the associated one of the pistons, and a flow restrictor for restricting flow of the hydraulic fluid discharged from the pressure chambers.

Vehicle speed responsive variable torque transmitting assembly

A guide follower of a vehicle for a transportation system is coupled to an onboard steering linkage by a bendable cable or equivalent. The bendable cable is taut to transfer the guide following movement of the guide follower to the steering linkage and is relaxed to disconnect the movement transmitting connection between them.
