Multi axle steered motor vehicle - has steering linkage for producing instantaneous centre of rotation with variable radius

摘要

Steering system ensures that the centre of the turning circle is on the extension of the rear axle when travelling on a road and the rear axle is locked for steering purposes. On travelling over difficult terrain the centre of the turning circle is steplessly adjustable and the rear and front wheel participate in turning. The centre on steering all wheels is on the line passing through the middle of the vehicle. The steering linkage has cranked levers for front wheels and for double rear wheels. These levers are connected to double arm levers between which is the actuating double arm lever connected to the steering column.
