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.
