Abstract: A power closure actuator for powering a movable closure includes an output member configured to drive movement of the movable closure, a motor coupled through a gear reduction to drive the output member, and an integrated brake-clutch unit having an input configured to receive drive power from the electric motor. The brake-clutch unit provides independent braking and clutching between the electric motor and the output member via an electric brake actuator and an electric clutch actuator, respectively. Brake and clutch portions of the brake-clutch unit act on a rotor, and brake force can be maintained on the rotor without powering the brake actuator. A clutch disc is biased disengaged from the rotor. The integrated brake-clutch unit provides a drive state between the electric motor and the output member when the brake portion is released concurrently with the clutch portion establishing a power coupling between the clutch disc and the rotor.

Abstract: A power closure actuator for powering a movable closure includes a shaft situated between an electric motor and an output member. A brake device along the shaft is actuable via an electric brake actuator to apply braking. An active brake clamp is movable by the electric brake actuator. An axially floating rotor is rotatable with the shaft and has a first axial side facing the active brake clamp a second axial side providing a second braking surface. A passive backing brake clamp is positioned adjacent the second braking surface. The axially floating rotor is biased away from the passive backing brake clamp by a first biasing member. Deflection of the first biasing member coupled with axial movement of the active brake clamp and the axially floating rotor enables braking by pinching action of the axially floating rotor between the active brake clamp and the passive backing brake clamp.

Abstract: A vehicle body closure system for a service port or storage compartment formed in the body. The closure system includes a door coupled to the vehicle body for movement between open and closed positions. A seal between the body and door requires compression for closure. A powered closure device including a motor and rotary output is operable for electrical energization in a powered mode of the closure system to release the door from the closed position, and the powered closure device also provides a powered mode for closing the door. A backup release mechanism is operable in a manual mode of the closure system, without energizing the powered closure device, to release the door. The door is locked closed automatically by a drive connection through which the powered closure device moves the door. The drive connection is maintained and not interrupted when releasing the door via the backup release mechanism.
