FIELD: transportation.
SUBSTANCE: invention relates to a vehicle with a hydraulic power-assisted driven axle. Vehicle comprises driving axle (10), driven axle (20), hydraulic pump (14) and hydraulic motor (24). Driving axle (10) comprises differential (11). Pump (14) comprises a rotor and a stator, the stator being mounted fixed with respect to the chassis and the rotor being connected to and rotating as one with differential box (11). Hydraulic pumps (10) are rotationally driven at a speed equal to the average speed of the two half axles associated with differential (11) on which this pump is mounted.
EFFECT: simplification of design.
