Clutch/brake drive unit
First Claim
1. A washing machine including a clutch/brake drive unit, said drive unit comprising a frame, a driving member and a driven member mounted coaxially for independent relative rotation with respect to the frame, a clutch including a clutch disc and mutually opposed frictional engagement surfaces respectively associated with the driving member and the driven member, said clutch being selectively engageable to permit the transmission of torque between the driving member and the driven member, a brake including a brake disc and mutually opposed frictional braking surfaces respectively associated with the driven member and the frame, said brake being selectively engageable to retard rotation of the driven member with respect to the frame, and a solenoid disposed intermediate the clutch and the brake such that energization of the solenoid causes the brake to be released and the clutch to be engaged, said washing machine further including a spin bowl connected with the driven member, and an agitator couplable with the driving member.
