A suspension assembly has a pair of suspension arms, namely a forward suspension arm and a rear suspension arm. Each suspension arm is pivotally mounted on a housing containing spring means associated with each of the suspension arms. A wheel hub assembly is mounted at an outer end of each suspension arm. An inner end of each suspension arm is connected by a pivot shaft with a lower end of an associated lever arm mounted within the housing. An upper end of the lever arm is connected to the spring means. The spring means opposes pivotal movement of the suspension arm away from a neutral position. Mounting flanges on the housing allow the assembly to be bolted to a floor of a vehicle and adjusted for correct alignment on the vehicle.

A suspension assembly as claimed in claim 13 wherein swivel bearings are provided between each end of the hydrostut and the support frame and the lever arm. 17. A suspension assembly as claimed in claim 1 wherein a rocking beam is mounted at an outer end of each suspension arm, a centre of the rocking beam being pivotally mounted on the suspension arm by a pivot pin extending between the beam and the suspension arm for pivotal movement about a horizontal pivot axis, a wheel or track support being mounted at each end of the rocking beam. 18. A suspension assembly as claimed in claim 17 wherein track supports are mounted at each end of the rocking beam and a wheel support is mounted co-axially with the pivot pin on the rocking beam or suspension arm. 19. A suspension assembly as claimed in claim 1 wherein the support frame forms a bogie with means for pivotally mounting the bogie on the bottom of the vehicle hull, the bogie having means for connection to a steering system of the vehicle for controlled pivoting of the bogie in response to a steering command from the steering system. 20. A suspension assembly as claimed in claim 19 wherein steerable wheels are mounted at the outer ends of the suspension arms by swivel mounts, a steering arm of the swivel mount being connected by a drag link to a fixed mounting point to provide differential steering of the wheels in response to rotation of the bogie. 21.
