Embodiment Construction

[0044] In the drawings, the same reference numerals designate the same components.

[0045] The compact hydraulic assembly 12 according to the invention comprises a housing 16 in which the hydraulic motor 11 is accommodated.

[0046] The hydraulic assembly also includes a differential housed in the same housing, the output shaft 18 of which is coupled to the traction wheels of the vehicle.

[0047] The differential has a case 4 containing satellite gears 1 cooperating with planetary gears 2 connected together with the output shaft of the differential and coupled with traction wheels (not shown) of the vehicle.

[0048] The free ends of the shafts of the satellite carrier 14 are connected together to the case of the differential.

[0049] Satellite gears cooperate with planetary gears to distribute torque to output shafts.

[0050] The differential is rotatably mounted inside the hydraulic motor, and the axis of rotation XX' of the hydraulic motor coincides with the axis of r...

Abstract

A compact hydraulic unit (12) for providing a vehicle with drive power, comprising a housing (16) in which a hydraulic motor (11) is housed comprising a distribution plate (13), a plate (17) supporting floating cylinders (9), a plate (3) axially holding the floating cylinders on the support plate, arranged to either side of a common fixed plate (10) and fixed pistons (6, 7) arranged between the plate and the floating cylinders and cooperating with them; said hydraulic motor converting the energy coming from a pressurised fluid into mechanical energy in the form of torque driving a differential, contained in the same housing, and wherein the output shafts (18) are coupled to the drive wheels of the vehicle; said differential comprising a casing containing planet pinions (1) engaging with planetary gears (2) integral with the output shafts of the differential, coupled to the drive wheels of the vehicle and configured to distribute the torque to the output shafts, wherein the differential is mounted in rotation inside the hydraulic motor, and the axis of rotation (XX') of the hydraulic motor coincides with the axis of rotation of the differential.

Description

[0001] This application claims priority from French patent application No. 1251720 filed February 24, 2012, the content of which (text, claims and drawings) is hereby incorporated by reference. technical field [0002] The present invention relates to hydraulic hybrid vehicles, and more particularly, to a hydraulic module comprising one or more hydraulic motors coupled to a vehicle differential for supplying tractive power to the wheels of the vehicle. Background technique [0003] A hydraulic hybrid vehicle differs from a hybrid electric vehicle in that it replaces an electric power source with a hydraulic power source. [0004] In hydraulic hybrid vehicles, a closed hydraulic circuit replaces or assists a traditional gearbox. [0005] A source of rotational energy (usually a thermal or electric motor) drives one or more positive displacement hydraulic pumps, preferably with high precision variable cylinders. [0006] Hydraulic pumps convert mechanical energy into hydrauli...
