ABSTRACT:
A clutch and brake assembly for alternately coupling a machine input shaft to a clutch disc or a brake disc for applying a driving torque or a braking torque to the input shaft. An axially movable cylinder is connected to a brake plate and a clutch plate. An annular piston is carried by a hub fixed to the input shaft and is connected to a rotor spaced at an axially fixed distance from the piston. The brake disc is positioned between the brake plate and the rotor while the clutch disc is positioned between the clutch plate and the rotor. A spring force normally urges the brake disc into engagement with the rotor. A pressure chamber is formed between the piston and cylinder and a passage is provided for admitting pressurized fluid to the chamber, thereby overcoming the spring force to urge the clutch disc into engagement with the rotor.
