ABSTRACT:
A torque transmitting assembly in the form of a rotational speed differential responsive type joint is disclosed. It comprises a drive housing as a first rotary member and a rotor as a second rotary member. The second rotary member is disposed in the first rotary member. A hydraulic fluid arrangement transmits at least a portion of the input torque from one of the first and second rotary members to the other in response to a rotational speed of the second rotary member and also to a rotational speed differential occurring between the first and second rotary members. Specifically, it includes an internal cam surface formed on the first rotary member and surrounding the second rotary member, cam followers in radially outwardly opening bores formed in the second rotary member in slidable engagement with the cam surface and reciprocable in response to the rotational speed differential to define variable volume chambers in the associated radially outwardly opening bores, respectively, and a flow restricter for restricting flow of hydraulic fluid discharged from each of the associated one of the cam followers. The cam surface is contoured such that at any angular position of the second rotary member relative to the first rotary member, substantially the same ratio of the input torque is transmitted from one of the first and second rotary members to the other during the occurrence of the rotational speed differential.
