Abstract
The utility model provides an electric vehicle rear axle, comprising an electric motor, a speed change device, an axle housing, a half shaft, an axle leg, a hub and a brake. The utility model is characterized in that a differential is provided, the electric motor is fixed on the axle housing therein, the electric motor output shaft thereof is fixed with the drive end of the speed change device, the output end of the speed change device is fixed with the differential, and the half shaft is connected between the differential and the hub separately. The device solves the problem that differentials are not provided in some electric vehicles. The device also combines the electric motor, the speed change device and the rear axle into one organically. The device provides the advantages of compaction and simple structure, low manufacturing cost, easy maintenance, and the solving of rear wheel differential problem.
Description
The utility model provides a kind of battery-driven car back axle, belongs to the placement technique field of axle unit and vehicular propulsion.
Battery-driven car has advantages such as energy-saving and environmental protection because of it, and obtains gradually promoting.But traditional three-wheel or four-wheel electric motor car, its chassis generally all with the fuel combustion vehicle structural similitude, electrical motor, change speed gear box, back axle three big parts are separate, come transferring power with belt, chain or transmission shaft between them, so the structure more complicated, the kinetic energy transmission consumes big, the manufacturing cost height, each parts makes a noise greatly during work, belt, chain directly are exposed to air, aggravation wearing and tearing, not easy care, and needing the frequent elasticity of adjusting chain and belt, operation is trouble very; Some battery-driven car back axles are arranged at present, though electrical motor and speed reduction gearing are designed to an integral body, indifferential device on back axle can not solve the differential problem of two trailing wheels, brings many inconvenience to driving.
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, compact conformation, simple, low cost of manufacture, be convenient to maintaining, can solve the battery-driven car back axle of trailing wheel differential problem.
The purpose of this utility model is achieved in that
Comprise electrical motor, transmission system, axle housing, semiaxis, bridge leg, wheel hub and drg, it is characterized in that: set up diff, wherein electrical motor is fixed on the axle housing, its motor output shaft is captiveed joint with the drive end of transmission system, the mouth of transmission system is captiveed joint with diff, and semiaxis is connected between diff and the wheel hub.
Described battery-driven car back axle, transmission system comprise two tooth ingear reducing gear, and wherein first reducing gear is captiveed joint with motor output shaft, and second reducing gear captiveed joint with the diff shell.
Described battery-driven car back axle, an end of semiaxis is captiveed joint with the diff mouth by spline, and its other end and wheel hub are rigidly connected.
Its principle of work is: the electrical motor outputting power, after slowing down by transmission system, pass to diff, again by diff with transmission of power to semiaxis and wheel hub rigidly connected with it, thereby driving is fixed on the wheel on the wheel hub, makes normal vehicle operation.
The utility model compared with prior art has following advantage:
1, changed traditional electrical motor, change speed gear box, the separate structure of back axle three big parts, it organically has been integrated in one, compact conformation, simple, low cost of manufacture is convenient to maintaining;
2, set up diff, solved the differential problem of two trailing wheels, make vehicle performance more perfect.
Fig. 1 is a structural representation of the present utility model;
Below in conjunction with accompanying drawing the utility model is described further:
1, wheel hub 2, drg 3, semiaxis 4, bridge leg 5, bearing 6, diff 7, diff shell 8, reducing gear 9, axle housing 10, reducing gear 11, motor output shaft 12, electrical motor
Electrical motor 12 is fixed on the axle housing 9, be installed with reducing gear 10 on its motor output shaft 11, reducing gear 10 is meshed with reducing gear 8, reducing gear 8 is rigidly connected through bolt and diff shell 7, one end of semiaxis 3 is captiveed joint with the mouth of diff 6 by spline, and its other end and wheel hub 1 are rigidly connected.Have bearing 5 to support between bridge leg 4 and the diff 6, and bridge leg 4 is rigidly connected with axle housing 9.
