ABSTRACT:
A steering mechanism particularly suited for vehicles of the type having a variable width track. The steering mechanism is flexible enabling it to automatically extend and retract laterally along with the track of the wheels of the vehicle. The mechanism acts on steering arms of the steerable wheels of a vehicle to simulate a conventional tie rod type of steering geometry. During turning, the inner wheel turns more than the outer wheel to minimize tire slippage or scrub. A flexible steering linkage assembly is connected between the steering arm ends of the pair of steerable wheels to maintain controlled spatial relationship between them which results in a simulation of tie rod steering geometry.
