Automatically adjusting friction torque device

摘要

A friction device includes an adjustment mechanism 42 for adjusting the device in response to wear on a friction surface within the device. The adjustment mechanism 42 includes a first cam ring 46 and a second cam ring 48 adjacent the first cam ring 46. In one embodiment, the first cam ring 46 is adapted for axial, but non-rotational movement with respect to a cover 32 of the friction device, the cover 32 being secured to a driving member 22 for transmitting torque. The second cam ring 48 is adapted for <IMAGE>
