Posidyne CLUTCH BRAKE
A clutch/brake is a combination of both a clutch stack and a brake stack operating about a common output shaft. As a centrally located piston is shifted to exert clamping pressure on the clutch stack, torque is transmitted from the input shaft to the output shaft.
When shifted away from the clutch stack to the brake stack, the clutch is automatically released and braking torque is transmitted to the output shaft.
The single-centrally located piston prevents clutch and brake overlap.
