Abstract

A vehicle power liftgate cable drive has a cable drive housing. An electric motor with a motor housing and an output shaft is secured to the cable drive housing. A clutch pack with a first clutch driven by the output shaft and a second clutch driven by the first clutch, is mounted in the cable drive housing. One of the clutches in the clutch pack is a one way clutch and the other clutch is an electromechanical clutch. A pinion gear is driven by the second clutch. A driven gear is rotatably journaled on a fixed shaft and driven by the pinion gear. The cable drum is attached to the driven gear. A coil spring has one end fixed to the fixed shaft and its other end attached to the cable drum. The fixed shaft is rotated to preload the coil spring in a direction that tends to wind a cable on the cable drum and then the fixed shaft is fastened to the cable drive housing. A cable is attached to the cable drum and to the liftgate.
