Abstract:
A torque transmitting device includes a first race, a second race, and a biasing member. The torque transmitting device selectively transmits a torque in a rotational direction between a first member and a second member. The second member includes a surface that defines an annular bore having a decreasing diameter in an axial direction. The second race opposes the first race and includes a surface that opposes the second member and has the decreasing diameter in the axial direction. The first race and the second race define a predetermined torque limit. The biasing element biases the second race against the second member with a predetermined force that contributes to a predetermined holding torque between the surface of the second race and the surface of the second member that is less than the predetermined torque limit.
