ABSTRACT:
Apparatus for driving and steering an invalid chair, or other light wheeled vehicle, comprises a transverse drive transmission shaft (8) with end cones (9 and 10) which contact across the periphery respectively of each of a pair of road wheels (11 and 12). By transverse axial movement of the drive transmission shaft the contact diameter of the cones can be varied and thus the relative speed of the road wheels controlled for differential steering.
