Abstract
A brake mechanism having a motor output shaft outputting a driving torque in a power-in and a power-out direction. A camming device operably couples the output shaft to a drive shaft for fixed rotation. A one-way clutch operably couples the drive shaft and a brake device. The brake device is normally in an engaged position that prevents rotation of the clutch device. During a holding maneuver, the one-way clutch, camming device, and brake device cooperate to prevent uncommanded movement. However, the nature of the one-way clutch permits free rotation during a power-in direction and the nature of the camming device permits free rotation during a power-out direction.
