ABSTRACT:
A vehicle transmission includes a plurality of driven gears comprising a series of concentrically spaced ring gears. Each ring gear of the plurality of driven ring gears has an inner diametrical surface and an outer diametrical surface. Each outer diametrical surface is configured to slidingly engage the inner diametrical surface of an adjacent ring gear. The vehicle transmission further includes a biasing means for biasing each ring gear away from a driven shaft and a selective engagement means for selectively engaging one ring gear of the plurality of ring gears with the driven shaft.
