<p>The invention relates to a multi-terrain vehicle which combines the advantages of an air-cushion vehicle with the manoeuvrability of a two-wheeled vehicle such as a motorcycle. In an example described, the vehicle comprises a frame (2) which supports two road-wheels (4) in tandem on a longitudinal chassis member (6). An engine (8) provides power to the rear wheel (4) and to a lifting fan (12). A passenger cabin (14) is mounted above a skirt arrangement (20) surrounding a plenum chamber. The skirt (20) is maintained in a plane substantially parallel with the ground by tilting relative to the frame (2) as the vehicle negotiates bends and curves in which the frame (2) leans in the manner of a motorcycle. An example of a suitable mechanism for this purpose is described, which comprises a rack-and-pinion device (66, 68) and at least one pair of double-acting piston-and-cylinder devices (32).</p> |
