Abstract
The utility model relates to a power transmission system of an electric motor car, in particular to a connection structure between a motor and a rear driving axle of an electric motor car, which belongs to the technical field of mechanical processing. The motor is directly mounted on a speed reducer through a flange, and the axial line of the motor is perpendicular to the flange surface of the speed reducer and is parallel to the axle housing of the rear driving axle and axle shafts. The motor is in bolted connection with the speed reducer, the motor power is transmitted to the speed reducer through a spline to achieve the speed reduction effect, the differential gear of a differential drives the axle shafts in a left shaft sleeve and a right shaft sleeve, and then drives wheels to rotate to generate driving force for driving the electric motor car to travel.
Description
Technical field
The utility model relates to a kind of battery-driven car power drive system, is specifically related to a kind of electric vehicle motor and rear driving axle connection structure, belongs to the Machining Technology field.
Background technology
At present, the traditional energy automobile power is provided by driving engine, by the mechanical type driving system with power transmission to drive wheel, realize the driving of vehicle.The mechanical type driving system mainly is made up of power-transfer clutch, change-speed box, universal driving device and drive axle, and wherein universal driving device is made up of universal joint and drive shaft, and drive axle is made up of the driving device of main reduction gear and diff drive wheels, axle housing etc.If traditional mechanical type driving system directly applies on the pure electric four-wheel vehicle of low-speed small, be subjected to the restriction of present pure electric vehicle tractive performance and electrokinetic cell, traditional mechanical type driving system, its structure is too complicated, quality is excessive take up room many, processing charges is higher, is unsuitable for direct application.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of electric vehicle motor and rear driving axle connection structure are provided, motor is directly installed on the retarder by flange, and electrical axis is vertical with the retarder flange face, and is parallel with rear driving axle axle housing and semiaxis.Bolt together between motor and the retarder, motor power reach retarder by spline and reach the deceleration effect, and the semiaxis in the moving left and right bushing of the differential cingulum of diff drives wheel revolutions, produces propulsive effort, drives battery-driven car and travels.
The utility model is realized with following technical scheme: a kind of electric vehicle motor and rear driving axle connection structure, it includes motor, retarder and diff, it is characterized in that: the reductor flange is arranged on the housing of described retarder, and motor is connected with the reductor flange with bolt by the back axle flange.
Described motor output end female splines is connected with the retarder male splines, and the spline that the diff differential gear drives the left and right sides semiaxis in the axle housing rotates semiaxis, is driven the rotation of wheel by semiaxis.
The beneficial effects of the utility model are: motor directly links to each other with the rear driving axle retarder, and is simple in structure, and power transmission is direct, and the driving efficiency loss is little, has not only effectively reduced complete vehicle weight, has improved the continual mileage of pure electric vehicle simultaneously.Motor is connected and fixed mode for being threaded with retarder, and easy to be reliable, cost is low, is convenient to dismounting and maintenance, is fit to the dynamic characteristic of pure electric four-wheel vehicle.

Among the figure, 1, motor, 2, retarder, 3, diff, 4, semiaxis, 5, wheel, 6, the reductor flange, 7, bolt, 8, the back axle flange.
The specific embodiment
As shown in the figure: a kind of electric vehicle motor and rear driving axle connection structure, it includes motor 1, retarder 2 and diff 3, and reductor flange 6 is arranged on the housing of described retarder 2, and motor 1 is connected with reductor flange 6 with bolt 7 by back axle flange 8.
Described motor 1 mouth female splines is connected with retarder 2 male spliness, and the spline that diff 3 differential gears drive the left and right sides semiaxis 4 in the axle housing rotates semiaxis 4, is driven the rotation of wheel 5 by semiaxis 4.
Working process: its power is directly reached the deceleration effect and transfers to diff 3 by retarder 2 by motor 1, and by 4 rotations of diff drive semiaxis, drive the rotation of wheel 5 by semiaxis 4, realize the driving of vehicle, transmission course is easy, and the motor power loss is little, the transmission efficiency height, the motivation package transmission connects arranges easy compactness, is easy to arrange.
