Abstract
A brake/locking differential for connecting a first shaft to a second shaft so that the shafts are either braked to a stop or rotated at the same speed, the differential including a clutch plate mounted on one of the shafts and a friction plate mounted on the end of the other shaft for axial motion into engagement with the clutch plate, a frame fixedly mounted with respect to the shafts, a cam plate mounted in the frame in a parallel relation to the friction plate, a sealed thrust bearing mounted on the other of the shafts for axial motion into engagement with the friction plate, an actuator plate positioned between the cam plate and the bearing for moving the bearing and friction plate into engagement with the clutch plate, and a brake ring mounted on the frame for moving the friction plate into engagement with the clutch plate to brake the rotary motion of the shafts and further including a compensating assembly for adjusting the axial position of the actuator plate, thrust bearing, brake plate and friction plate to compensate for wear of the friction pads on the friction plate.
