<p>A multi-purpose four-wheel drive vehicle is disclosed having four-wheel steering. A hitch (68) is slung below the vehicle body between the front and rear wheels or forward of the front wheels. By alinging the hitch in this manner the force applied to the rear wheels and also the front wheels, to move the vehicle forward, is given a component towards the ground so that the heavier the load towed and the greater traction required to pull the load the greater the vertical force applied to the wheels thereby increasing traction between these wheels and the ground. The multi-purpose vehicle incorporates a relatively high ground clearance which is achieved by employing four vertical axles and wheels situated at the four corners of a main frame body of the vehicle. The vertical axles are situated in respective spaced-apart leg post members (54a to 54d), each leg post member being rigidly interconnected by two spaced-apart longitudinally extending frame members (50,52) and two spaced-apart transversely extending frame members (56,58). At least three (50,52,56) of the frame members are of torsionally resilient construction. The vehicle incorporates a belt or chain and sprocket transmission for driving the vehicle which can also be used as an amphibious transporter.</p> |
