VEHICLE WITH HYDRAULIC ASSISTANCE BY TRANSMITTING TORQUE FROM A DRIVING AXLE TO A DRIVEN AXLE

摘要

The present invention relates to a vehicle comprising a driving axle (10), a driven axle (20), a hydraulic pump (14) and a hydraulic motor (24) providing hydraulic assistance for driving the driven axle (20) by tapping off torque applied to the driving axle (10), characterized in that the driving axle (10) comprising a differential (11) thus defining two output half axles on which wheels are mounted, rotation of the box allowing said output half-axles to be rotationally driven at distinct speeds, the pump (14) comprising 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 the differential box (11), the hydraulic pumps (10) being rotationally driven at a speed equal to the average speed of the two half axles associated with the differential (11) on which this pump is mounted.
