Patent ID: 8601904

Claim:
A force transmission assembly, for transmitting forces between an input and an output, the force transmission assembly comprising: a force transmission device including a stationary shaft defining a central axis; and a force-accompanying device including: a cam being movable in rotation about the shaft; a pusher mounted about the shaft to be movable in translation along the shaft with the cam and which pusher includes a body having cam rollers mounted thereto so as to be engaged with and movable relative to a cam path of the cam, and a ball bushing secured within the body and about the shaft, the ball bushing being engaged with the shaft so as to be fixed from rotation about the shaft and to be movable in translation with the body along the shaft; and a resilient member mounted about the shaft so as to be compressible by the pusher to thereby exert force to engage the cam rollers against the cam path.
