摘要： A power liftgate device for a liftgate of a vehicle having a power drive unit and a pneumatic actuator. The pneumatic actuator is pivotally coupled between the liftgate and the vehicle and exerts a force opposing retraction of the liftgate. A driven gear is fixed to the pneumatic actuator to pivot therewith and is selectively driven by the power drive unit. The liftgate assembly further includes an engaging device that is coupled to the vehicle for engaging the power drive unit with the driven gear, thereby enabling the power drive unit to drive the driven gear. Specifically, the engaging device is positionable between an engaged and a disengaged position, wherein the engaging device is operable in the engaged position to engage the power drive unit into driving connection with the driven gear. The engaging device is also operable in the disengaged position to disengage the power drive unit from the driven gear to enable the actuator to actuate freely.

摘要： A liftgate self-closing device for a vehicle includes a power drive unit and a track drive member drivingly interconnected with the power drive unit. The power drive unit selectively drives the track drive member. A pneumatic actuator is pivotally coupled at one end to the liftgate and at the other end to the track drive member. The actuator exerts a force opposing retraction of the liftgate. The power drive unit is operable in a first and a second direction. The first direction of the power drive unit drives the track drive member such that the pneumatic actuator is lowered to a predetermined position to enable the liftgate to automatically close. The second direction of the power drive unit drives the track drive member in an opposite direction such that the pneumatic actuator is raised to a predetermined position to enable the liftgate to be opened by an operator.
