Embodiment Construction

[0023] The present invention is described in detail below in conjunction with accompanying drawing:

[0024] The purpose of the patent of this invention is to provide a wheel hub motor hydraulic drive system installed on the front wheel (non-drive wheel), so as to overcome the shortcomings of poor passability of commercial trucks on bad roads, improve the performance of the car, and improve its fuel economy sex.

[0025] refer to figure 1 , the hub motor hydraulic drive system includes (engine 1, clutch 2, gearbox 3), power take-off 4, variable pump 14, hydraulic control valve group 6, and two radial piston variable hubs with the same structure hydraulic motor9.

[0026] The power take-off 4 includes a housing, an input shaft, an output shaft, an input shaft gear, an output shaft gear and two pairs of rolling bearings.

[0027] The input shaft and the output shaft are installed on the casing through rolling bearings and are in the same horizontal plane, and the rotation ax...

Abstract

The invention discloses a hydraulic driving system for a hub motor, wherein the engine (1) is connected with an input shaft of the transmission case (3) through the clutch (2); an input shaft of the power takeoff (4) is connected with a middle shaft of the transmission case (3); an output shaft of the power takeoff (4) is connected with an input shaft of the variable pump (14); the high-pressure oil outlet of the variable pump (14) is connected with the high-pressure oil inlet of the hydraulic control valve bank (6); the lower-pressure oil inlet of the variable pump (14) is connected with the lower-pressure oil outlet of the hydraulic control valve bank (6); the hydraulic control valve bank (6) is formed by a No.1 overflow valve (15), a No.2 overflow valve (16) and a three-position four-way reversing valve (16) with O-type meso-position function, the A port and B port of the three-position four-way reversing valve (16) in the hydraulic control valve bank (6) as the high pressure oil outlet and oil inlet are connected with the oil outlet and oil inlet of the two hub hydraulic motors (9) in same structure equipped on the two front wheels (13) through the high pressure pipe lines(7).

Description

technical field [0001] The present invention relates to a drive system for a hybrid electric vehicle, and more particularly, the present invention relates to a hydraulic drive system of a wheel hub motor mounted on the front wheel of the vehicle. Background technique [0002] Energy saving and environmental protection are the two major themes of automobile development in the 21st century. Electric vehicles are ideal substitutes for traditional fuel internal combustion engine vehicles. A feasible solution to the above problems. [0003] Hydraulic hybrid vehicles are in the research stage of universities in China, and the relevant hydraulic drives are parallel systems with relatively simple structures. In foreign countries, American Eaton Company has applied hydraulic drive hybrid technology to various types of vehicles, such as cars, pickups and urban buses. Its parallel hydraulic auxiliary system HLA has been successfully applied to heavy-duty garbage trucks, improving fuel...
