Abstract:
A drive system drives a pulley along a curved track to open and close a sliding vehicle door. The pulley is pivotally mounted to the sliding door to permit the pulley to pivot during traverse of the curved portion of the track. An electric motor driven pulley remotely drives the pulley through a drive belt. In operation, as the pulley pivots during traverse of the curved portion of the track, the drive belt twists. Torque transfer between pulleys is maintained during twisting of the drive belt which thereby permits an uncomplicated yet effective system for driving the sliding door along the curved portion of track. Another drive system transmits torque to pulley through a drive shaft which rotates during traverse of the curved portion of track.
