An assembly, which can be incorporated within a variable track vehicle, enables the location of the road wheels concerned to be altered from retracted to extended configuration and also enables such wheels to be steered at all times, including during retraction or extension. The assembly involves pairs (disposed symmetrically about the vehicle centre line) of rods, including rods 10 and 11, forming upper and lower parallelograms. Suspension and steering components are connected to the outer members of such parallelograms. Wheel location is effected by movement of a ram 24 acting though other components on rods 11. Steering is effected by a pair of push-pull cables, fixed to the chassis and acting on the wheels hubs, arranged such that the steering angle is substantially independent of the vehicle track dimension. |
