Abstract
A friction device includes an adjustment mechanism for adjusting the device in response to wear on a friction surface within the device. The adjustment mechanism includes a first cam ring and a second cam ring adjacent the first cam ring. In one embodiment, the first cam ring is adapted for axial, but non-rotational movement with respect to a cover of the friction device, the cover being secured to a driving member for transmitting torque. The second cam ring is adapted for rotational movement with respect to the cover and the first cam ring. The first cam ring has a plurality of annular ramped surfaces on an axial face of the first cam ring. The second cam ring has a plurality of annular ramped surfaces on an axial face opposing the axial face of the first cam ring. The second cam ring is rotated with respect to the first cam ring such that the ramped surfaces cam against each other to increase the axial displacement of the first cam ring and the second cam ring, whereby the axial displacement is adapted to compensate for wear on a friction surface of a member of the friction device.
