A modular drive assembly for a sliding door, comprising: a guide track having a hinge slidably received therein; a pair of pulleys disposed on either end of the guide track; a pair of cables each having an end that is secured to the hinge and the other end is secured to a cable drum of a motor drive unit mounted to the guide track, the motor drive unit being configured to rotate the cable drum, wherein the cable drum is also capable of freely rotating within the motor drive unit when the motor drive unit is not rotating the cable drum, wherein rotation of the cable drum causes the hinge to move in the guide track as one of the cables wraps onto the cable drum while the other one of the cables wraps off of the cable drum.

Apparatus and method for providing a modular sliding door mechanism

A self-backdriving jackscrew apparatus including a biasing member connected to a screw portion of a jackscrew that exerts backdriving force on the screw to turn the screw in a rotational direction that returns a nut portion of the jackscrew to a home position on the screw.

Self-backdriving jackscrew apparatus

A passenger van is equipped with a drive mechanism for power operation of a slideable side door. The drive mechanism has a flexible drive member that travels in a closed loop which includes travel through a center track that supports and guides a hinge and roller assembly that is attached to the rear of the side door. The flexible drive member has a cogged portion that is driven by an electric motor to open and close the side door. The remaining portion is uncogged for economy o f manufacture and for releasing the flexible drive member from a clutch of the hinge and roller assembly to open the side door manually very easily. An electromagnetic clutch may also be included to reduce manual operating effort.

Drive mechanism for power operated slideable side door

A passenger van is equipped with a drive mechanism for power operation of a slideable side door. The drive mechanism has an endless flexible drive member that travels in a closed loop which includes travel through a center track that supports and guides a hinge and roller assembly that is attached to the rear of the side door. A clutch is mounted on the hinge and roller assembly to clamp onto the flexible drive member for power operation. The clutch is operated by an actuator that includes a solenoid and a linkage between the solenoid and a moveable plate of the clutch. An electromagnetic clutch may be used as an alternative.
