<p>A short, narrow motor vehicle has a parallelogram linkage at each side to which the front (or rear) road wheels are connected. This enables these wheels to be displaced, laterally and lengthwise, in a co-ordinated way. If the displaceable wheels are the front wheels, a steering mechanism is provided to enable the wheels to be steered irrespective of the extent of their displacement, including during actuation of the displacement mechanism. The figure shows, in plan view, steerable 13 front wheels (28) at their maximum lateral displacement. In this diagrammatic representation, control of steering is by means of handlebars (15) acting through various meshing gears, chains and sprockets; and control of the lateral and lengthwise displacement is by means of a lever (3) acting through other meshing gears and pivotally connected elements. </p> |
