Abstract

Describes a steering system in an all-terrain four-wheeled vehicle with independent suspension where the necessary forces for steering control are supplied by cable and pulley actuators with the cable running parallel to the suspension arm between vehicle frame and wheel, steering control by the driver is by manipulation of right and/or left steering levers eliminating the need of steering wheel and steering column in front of the driver. The steering actuators are independent and there is no linkage for coordinating their turning angles. Close coordination of the wheel turning angles for achieving the turning angle relation between the wheels is by a non-linear linkage whereby the actuators are provided with separate displacement motions with the non-linear relation to achieve the desired relation between the steering angles of the wheels.
