Abstract
A swing door actuation system for moving a door about a pivot axis between open closed positions relative to a vehicle body. The system includes a power swing door actuator having a housing connectable to one of the swing door and the vehicle body, an extensible member that moves relative to the housing, and connects to the other of the swing door and the vehicle body, a motor connected to a gear train, and a normally engaged clutch. The motor is operatively connected to a clutch input end through the gear train. The output end is operatively connected to the extensible member. The clutch is disengageable to disconnect the motor from the extensible member. The clutch has a slip torque that is sufficiently high to prevent movement of the door when the door is exposed to less than a selected external torque and the motor is stopped.
