Abstract
A clutch and brake apparatus for being mounted in a housing comprises first clutch having an annular shape and second clutch functioning as a brake adjacent the first clutch, the second clutch having an annular shape and being concentrically disposed with the first clutch. A pressure plate is mounted for non-rotating movement toward and away from the first and second clutches for selectively engaging at least one of the first and second clutches and for holding the pressure plate in a rotationally stationary position with respect to the housing and second clutch. Structure is provided for urging the pressure plate toward both the first and second clutches and is operable to engage the first clutch. Roller bearings are interposed between the first clutch and the pressure plate to permit relative movement between the pressure plate and the first clutch. The first clutch is operable to rotate relative the pressure plate when force is applied by the pressure plate through the roller bearings and an annular piston is provided for moving toward the second clutch to selectively compress and engage the second clutch and selectively move the pressure plate away from the first clutch to disengage the first clutch.
