<p>TITLE SUSPENSION ASSEMBLY FOR OFF-ROAD VEHICLE A high mobility wheeled vehicle for transporting long loads, such as trimmed tree trunks or whole trees, over roadless terrain. The vehicle has front and rear quad wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of these assemblies about a roll axis disposed below and parallel to the longitudinal axis of the bed frame. A linkage type roll control means interconnects the quad wheel assemblies and the bed frame to proportionately control the relative angular movement of the bed frame with respect to the quad wheel assemblies. The roll control means includes a plurality of interconnected links plus a pair of power extensible links for selectively adjusting the steady state position of the vehicle bed relative to the quad wheel assemblies in either direction. In a modification, parallel links are employed to interconnect the quad wheel assemblies with pivotally mounted load supporting cradles.</p> |
