A hybrid drive axle

Abstract

The invention discloses a hybrid power drive axle. The hybrid power drive axle is characterized by comprising a gas pipe connector (1), a piston (2), a shifting fork (3), a return spring (4), a shifting fork shaft (5), a driving bevel gear (6), a differential mechanism axle shaft wheel (7), an axle shaft (8), a drive cylindrical gear (9), a thrust bearing (10), a first wet-type friction plate (11), a second wet-type friction plate (12), hubs (13), driving wheels (14), a hydraulic pipe (15), a high-pressure pipe (16), a bothway plunger pump cylindrical gear (17), a low-pressure liquid storage tank (18), a driven bevel gear (19), a bothway plunger pump (20), a gas isolation type energy accumulator (21) and a hydraulic mixing driving system. When a car is braked or goes down a long slope, a hydraulic pump participates in work, and the functions of car retarding, auxiliary braking and energy accumulation are achieved; when the car is started, the hydraulic pump has the effect of a hydraulic motor under pushing of stored hydraulic pressure or stored air pressure, and therefore the function of motor vehicle auxiliary braking is achieved; hydraulic hybrid driving directly acts on the drive axle, so that auxiliary driving is more direct and efficient; and meanwhile fuel saving and emission reduction of the car are achieved.

Description

Technical field: [0001] The invention relates to the field of motor vehicle drive technology, in particular to a hybrid drive axle, and its application field extends to hybrid motor vehicles with hydraulic drive and at least one energy storage device. Background technique: [0002] With the development of the new energy automobile industry, people pay close attention to the current R&D and industrialization of new energy vehicles. The current sales growth of new energy vehicles is mainly the growth of passenger cars, but the growth of new energy commercial vehicles—mainly liquefied petroleum gas buses , Liquefied natural gas buses, hybrid buses, etc. have also developed rapidly in recent years. In order to adapt to and meet the strong demand of the market - the demand for braking and slowing when the vehicle goes downhill for a long time, the demand for fuel saving and emission reduction in terms of environmental protection and lower operating costs, the demand for vehicle d...
