Claim 14:
15. A steering system for a vehicle having a frame with respective frame sides and suspended above solid front and rear axles, the steering system comprising:
a rack and pinion gearset configured with a slow steering ratio;
an augmented chain and sprocket assembly comprising an input shaft and an output shaft with a quick steering ratio of at least 1.5 to 1; and
wherein a turning of a steering wheel by a driver defines a steering input, the steering input refers to a rotational torque, the steering input is transmitted from the steering wheel through the augmented chain and sprocket assembly and the rack and pinion gearset to a pair of front wheels thereby causing the pair of front wheels to turn;, wherein the augmented chain and sprocket assembly further comprises:
an augmented chain and sprocket assembly housing;
a large sprocket having teeth and housed within the augmented chain and sprocket housing;
a small sprocket having teeth and housed within the augmented chain and sprocket housing;
a chain having chain links rotationally coupling the large sprocket and small sprocket, wherein the chain is housed within the augmented chain and sprocket housing;
an electric motor having a rotor and a cup-shaped gear with teeth and housed within the augmented chain and sprocket housing; and, wherein the input shaft is adapted to the large sprocket and output shaft is adapted to the small sprocket, the input shaft and the output shaft protrude through opposite sides of the augmented chain and sprocket housing.
