ABSTRACT:
A driverless vehicle having swivel-mounted support wheels which ride on track rails and at least first and second drive wheels adapted for frictional contact with a drive tube. The drive wheels are interconnected by a linkage permitting limited independent movement of the drive wheels through a track curve, and they are maintained in substantially synchronous angular orientations relative to the drive tube by means of a stationary cam and a follower mounted on one of the drive wheels or by means of a linkage interconnecting one of the support wheels with one of the drive wheels.
