ABSTRACT:
A drive-shoe assembly (30) and method for accelerating/decelerating a carrier unit (14) along a rail (12) or the like. The drive-shoe assembly (30) includes a rigid shoe segment (36) which frictionally engages the adjacent acceleration/deceleration drive wheels (22) operating at different speeds, and a movable segment (38) which supports the weight of the carrier unit (14) yet does not impart any significant velocity to the carrier unit (14). The movable segment (38) includes a plurality of roller elements (35) which are in rolling contact with higher or lower speed drive wheels adjacent to the drive wheels (22) controlling the carrier unit velocity so as to minimize drive wheel wear and insure smooth carrier unit acceleration.
