ABSTRACT:
A power train for a vehicle includes a gearbox with an input shaft and an output shaft and is configured such that the input shaft drives the output shaft at a single speed ratio in a first direction and a single speed ratio in a second direction. The output shaft is coupleable with the front and rear vehicle axles to separately drive each axle. Further, a continuously variable transmission is connected with an engine shaft and with the gearbox input shaft such that the engine shaft drives the input shaft within a range of speed ratios from less than 1 to greater than 3. Front and rear differentials are coupled with each axle and with the output shaft and drive the axles at different speed ratios such that a base surface drives the front axle independently of the front differential when at least one rear wheel rolls upon the surface.
