Abstract:
A steering system (10) for a vehicle wheel (12) has a wheel carrier (14) for mounting a steered wheel (12), the wheel carrier (14) being rotatably mounted with respect to the vehicle about a steering axis to allow the wheel (12) to be steered. A hydraulic cylinder (20) has a piston therein and a rigid connecting rod assembly (22) extending from the piston out of the cylinder (20). The rigid connecting rod assembly (22) comprises a first section (22) adapted to reciprocate into and out of the cylinder (20) and a second section (26) rigidly extending from the first section (22) to a pivot point connection (50) where it is pivotally connected to the wheel carrier (14) at an offset from the steering axis. The hydraulic cylinder (20) is pivotally mounted on the vehicle such that it is prevented from translational movement relative to the vehicle but capable of changing its orientation with respect to the vehicle. Due to the rigid connecting rod assembly (22) and the pivot connection to the wheel carrier (14), as well as the pivotal mounting of the cylinder (20) on the vehicle, lateral strains on the seals of the hydraulic cylinder (20) are avoided.
