Abstract:
In a vehicle having a chassis, a steering system comprising a pair of outwardly extending track rods, two wheels mounted for rotation on respective suspension subassemblies, each suspension subassembly comprising:a king pin fixed at a predetermined angle to the chassis; a steering arm connected to a respective track rod and configured to rotate about a king pin axis upon movement of the respective track rod and constrained so that said steering arm cannot move in an axial direction of the king pin; a wheel support member arranged for rotational movement about the king pin axis when the steering arm moves and comprising a member for rotating a respective wheel for rotation, the wheel support member mounted for reciprocal movement substantially in the axial direction of the king pin, such that movement relative to the chassis of a wheel carried by the wheel support member does not cause movement of a respective steering arm in the axial direction of the respective king pin, said movement of the respective steering arm being with respect to the respective king pin, thereby substantially eliminating toe and bump steer.
