Abstract
A cable drive for a motor-vehicle sliding door has a pair of cable sections of predetermined diameter and each having one end attached to the vehicle and an opposite end, a pin fixed on the vehicle, defining an axis, and having a screwthread of a pitch at least equal to the cable diameter, and a gear having a core threaded onto the pin. A pair of coaxial drums having smooth outer surfaces are axially coupled to but rotatable on the core and are each connected to a respective one of the opposite ends of the cable sections. A spring is engaged between and urges the drums rotationally oppositely to tension the cable sections. Interengaging formations on the gear and on the drums rotationally couple the drums to the gear and a reversible drive motor coupled to the gear simultaneously rotates the gear about the axis, axially displaces the gear on the pin, winds up one of the cable sections on the surface of the respective drum, and unwinds the other of the cable sections from the surface of the respective drum.
