ABSTRACT:
A gearbox mounted between axles for left and right follower wheels of a vehicle includes a countershaft parallel to the axles. The countershaft is rotated at a speed greater than those of the right axle by speed-increasing gears. The countershaft and the left axle are capable of being connected to each other through first and second shifting gears and a first hydraulic clutch and through third and fourth shifting gears and a second hydraulic clutch. The first and second hydraulic clutches are disposed back-to-back between the first and third shifting gears and therefore, the size of the entire gearbox can be reduced. Moreover, since the first and second hydraulic clutches are mounted on the countershaft which is rotated at the higher speed, the necessary torque transmitting capacities of the first and second hydraulic clutches can be decreased, leading to reduced sizes of the first and second hydraulic clutches.
