Abstract
A steering system for a vehicle having a steering wheel, steerable front wheels and steerable rear wheels. The system comprises a linkage arrangement operatively interconnecting the steering wheel with the front and rear wheels for steering the front and rear wheels in response to operation of the steering wheel. The linkage arrangement includes a mechanical linkage mechanically connected with the steering wheel so as to transmit steering effort. The mechanical linkage is provided with a restoring mechanism for exerting restoring force to said mechanical linkage so as to urge the steering wheel toward a neutral position thereof. Favorable returnability of the steering system is achieved in this arrangement.
