ABSTRACT:
An all-wheel steered vehicle in which all wheels are always parallel and have an equal role in steering the vehicle. It consists of a plurality of wheel assemblies capable of wheel rotation about the wheel's (10) axis. The shaft (14) of each wheel assembly passes through bearings (16) such that the shaft is fastened to the chassis (15) but rotatable in its vertical axis. Each shaft (14) is connected to a rotary shaft linkage (17) which when connected to the steering transmission linkage (18) each wheel assembly is maintained in parallel, but allowed to rotate simultaneously about their vertical axis. The vehicle body or seat (21) is attached to the central shaft (20) and is rotatable about the center of the chassis. The vehicle body or seat is in linkage with the wheel assemblies synchronous drive member such that a rotation of vehicle body or seat relative to the chassis causes a simultaneous and equal rotation of all the wheel assemblies about their vertical axis. That is, both the vehicle body or seat and all of the wheels are maintained parallel to one another. The steering mechanism is such that initiating a turn with the steering control on the vehicle body or seat, rotates the vehicle body or seat with respect to the chassis and simultaneously rotates all the wheels on their vertical axes, changing the direction of the vehicle. All wheels have an equal role in steering the vehicle.
