ABSTRACT:
A clutch/brake assembly for a machine having a rotating output shaft and a fixed mounting plate which includes an input disc coupled to the output shaft for rotation therewith and moveable axially relative thereto, an output disc moveable axially relative to the output shaft and rotatable relative thereto and a brake member fixed to the mounting plate and adjacent the output shaft. A high friction pad is mounted on the output disc for coupling the output disc to the input disc and for arresting the rotation of the output disc upon engagement with the brake member. Springs urge the input disc axially away from the output disc the output disc axially into engagement with the brake member. A cam assembly is coupled to the input disc and is movable from a first position to a second position for moving the input disc axially against the springs and into engagement with the high friction pad and for moving the high friction pad out of engagement with the brake member whereby the output disc is driven upon rotation of the output shaft,. The cam assembly is also operable upon movement from its second to its first position to permit the springs to move the input disc out of engagement with the high friction pad and the high friction pad into engagement with the brake member.
