Embodiment 1
[0014] Example 1, see figure 1 , figure 2 , image 3 , select appropriate components according to the design requirements; connect the first wet friction plate 11 with the external spline of the driving bevel gear 6 through the internal spline, and connect the second wet friction plate 12 with the internal spline of the driving cylindrical gear 9 through the external spline; The driving cylindrical gear 9 cooperates with the driving bevel gear 6 with a small gap, and can rotate relatively independently without axial force (that is, the motor vehicle is running normally); the bidirectional plunger pump (motor) 20 has its own bidirectional plunger pump cylindrical gear 17 meshes with the driving cylindrical gear 9; the driving bevel gear 6 and the driven bevel gear 19 are paired and meshed; the driven bevel gear 19 drives the differential axle wheel 7 to rotate together; The shaft wheel 7 is connected, and the flange at the other end is connected to the hub 13 through bolts; ...

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...
