Abstract: A steering assembly for a vehicle includes a forward apparatus positioned toward the front of the vehicle and having a first front wheel assembly and a second front wheel assembly. The steering assembly includes a gear having teeth and being pivotable about a pivot axis. The pivot axis is positioned between the teeth of the gear and the forward apparatus. A first front link is attached to the gear and to the first front wheel assembly to turn a first front wheel. A second front link is attached to the gear and to the second front wheel assembly to turn a second front wheel.

Abstract: A control mechanism for a dual transmission vehicle is disclosed. First and second overlaying plates are provided, the first plate having a profiled slot which communicates with parallel slots in the second plate. The slots in the first and second plates are oriented in the direction of rectilinear movement of their respective plate. The first plate is controlled to move in a direction normal to the direction in which the second plate is controlled to move. A pair of rods connects the plates to the transmissions. Each rod has a first end joined to its respective transmission and a second end projecting through the profiled slot in the first plate and through a respective one of the parallel slots in the second plate. Dependent on the relative position of the plates, wheels connected to the transmission are driven at the same or different speeds.
