摘要： 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.

摘要： A pedestrian truck (50) steered with a tiller (56) is operable in a first mode where a controllable front wheel (64) is aligned generally parallel with a front-rear center line of the truck, or a second mode where the wheel is generally perpendicular to the front-rear center line. A steering controller can operate in either a normal steering mode to steer the rear steerable wheel (52) in the same sense (clockwise or anticlockwise) as the tiller is rotated and in an alternate steering mode to steer the rear steerable wheel in the opposite sense to the rotation of the tiller. A steering mode selector is provided which automatically engages the alternate steering mode when the truck is in the second mode of operation and either (i) the tiller is positioned on the same side of the center line as the controllable front wheel and the drive direction is such that the tiller leads the truck (FIGS. 12-14), or (ii) the tiller is positioned on the same side of the center line as the castor front wheel (58) and the drive direction is such that the tiller trails the truck (FIGS. 4, 5).

摘要： An articulated vehicle [10] has a first body section [12], a second body section [14], and an elongate projection [22] projecting from the first body section [12] towards the second body section [14]. A pair of steering cylinders [36, 34] are mounted such that they are partially or wholly disposed in or on the elongate projection [22], and are disposed one above the other so they overlap vertically, thereby narrowing the projection at the end nearer the first body section [12] and allowing the second body section [14] to be rotated closer to the centre line. A rotatable shaft [40] of the second body section [14] is mounted towards the far end of the elongate projection [22] and is steered by a pair of linkages such as chains [42, 44], each of which is connected to the shaft [40] and to a respective one of the steering cylinders [36, 34]. The chains [42, 44] wrap around the shaft [40] with a circumferential overlap, though they are spaced vertically. This circumferential overlap allows steering angles significantly in excess of 180° to be achieved.
