| Abstract: |
A vehicle adapted to traverse uneven terrain, comprising a chassis and a plurality of wheel assemblies. The wheel assemblies each comprise a forward wheel and a rear wheel mounted on a common support structure. The support structure is supported for free pivotal movement on the chassis about a pivot axis located between the forward and rear wheels and is constructed and arranged such that the forward wheel of each wheel assembly supports less weight of the vehicle than the rear wheel of the respective wheel assembly. A stopper arrangement, which can take a variety of forms, is provided for limiting the pivotal movement of the support structures of each wheel assembly about the pivot axis. The stopper arrangement is adjustable for changing a range of free pivotal movement of the respective support structure. The vehicle can be a towed trailer-type vehicle with a wheel assembly on both sides, or a self-propelled vehicle with a wheel assembly located at each corner of the vehicle. The wheel assemblies can be provided with soft low pressure flotation tires or endless tracks.

What is claimed is:
1. A vehicle adapted to traverse uneven terrain, comprising:
- a chassis;
- first and second wheel assemblies, each wheel assembly comprising a forward wheel and a rear wheel, and a support structure on which said forward wheel and said rear wheel are rotatably mounted, said support structure being pivotally supported on said chassis about a pivot axis located between said forward and rear wheels;
- said support structure of each wheel assembly being constructed and arranged such that the forward wheel of each wheel assembly supports less weight of the vehicle than the rear wheel of the respective wheel assembly when the vehicle is traversing level terrain, and vertical movement of one of the forward wheel and the rear wheel induces synchronous movement in the other of the forward wheel and the rear wheel.
