Abstract
The utility model discloses an integrated drive axle for an electric automobile. The integrated drive axle comprises a reducer, a differential mechanism and a motor, wherein the motor is directly fixed on an axle housing of the axle; a transmission shaft of the motor is connected with an input shaft of the reducer; the differential mechanism is fixed on the axle housing; and an output shaft of the reducer is connected with the input end of the differential mechanism. The utility model has the advantages that the motor, the reducer and the differential mechanism are fixed on the axle body, all parts are connected stably, the transmission resistance and bumping loss during running are reduced, the transmission efficiency is improved and the service life of the motor is prolonged; in addition, the axle is fixedly connected with a chassis through a spring steel plate support, so that the gravity torque is reduced, the gravity is transmitted to the ground through wheels, the influence of the gravity on a rear axle is reduced and the rear axle is hardly damaged; and a drum brake device makes a brake system stable.
Description
Technical field
The utility model relates to a kind of electronlmobil inner structure parts, specifically is that a kind of electronlmobil integral type drives vehicle bridge.
Background technology
At present, the general design that adopts fuel vehicle of electric automobile chassis design is installed in motor on the chassis; Be connected with back axle with retarder through transmission shaft then, reach the purpose of powered vehicle, the electronlmobil that still adopts this design in motion; The stressing conditions that drives vehicle bridge is very complicated; When in vehicle is advanced, occurring jolting, the relative position between vehicle bridge and the chassis often changes, and transmission shaft often is in the state of telescopic variation, angle variation; Thereby the transmission resistance of vehicle and loss are increased, reduce driving efficiency; In addition, for the automobile of back-wheel drive, it drives vehicle bridge will bear the load weight of a large portion, and motor separates with the driving vehicle bridge, has more increased the weight of the degree of wear of electronlmobil, reduces the service life of motor.
The utility model content
The utility model technical matters to be solved provides a kind of driving efficiency height, motor long service life, and the non-damageable electronlmobil integral type of back axle drives vehicle bridge.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of electronlmobil integral type drives vehicle bridge; Comprise retarder, diff and motor, said motor directly is fixed on the axle housing of vehicle bridge, and motor transmission shaft is connected with reducer input shaft; Said diff is fixed on the axle housing, and the output shaft of said retarder is connected with the input end axle of diff.
Said axle housing is provided with the spring plate holder of captiveing joint with the chassis; On the body of a bridge of said vehicle bridge, be provided with drum brake system.
Adopt the beneficial effect that technique scheme produced to be: through motor, retarder and diff all are fixed on the vehicle bridge body of a bridge; Make motor and vehicle bridge be integrally formed the formula connection structure; Various piece connects stable; The loss of jolting when reducing the transmission resistance and going improves driving efficiency, prolongs motor service life; In addition; Vehicle bridge is captiveed joint with the chassis through the spring plate holder, makes in the spring plate holder of car body gravity near the wheel position, because of spring plate is tried one's best under the situation that does not influence assembling near wheel; Gravity torque is reduced; Gravity passes on the ground through wheel, reduces the influence that back axle receives gravity, makes back axle not fragile; Drum brake system makes brake system more stable.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Wherein, 1, axle housing, 2, flange, 3, reducer input shaft, 4, retarder, 5, diff, 6, the spring plate holder, 7, drum brake system.
The specific embodiment
Like Fig. 1, shown in Figure 2, the described electronlmobil integral type of the utility model drives vehicle bridge, comprises retarder 4, diff 5 and motor, and said motor directly is fixed on through flange 2 on the axle housing 1 of vehicle bridge, and motor transmission shaft is connected with reducer input shaft 3; Said diff 5 is fixed on the axle housing 1, and the output shaft of said retarder 4 is connected with the input end axle of diff 5.Axle housing 1 is provided with the spring plate holder 6 of captiveing joint with the chassis; On the body of a bridge of said vehicle bridge, be provided with drum brake system 7.
Through motor, retarder 4 and diff 5 all are fixed on the vehicle bridge body of a bridge, make motor and vehicle bridge be integrally formed the formula connection structure, various piece connects stable, and the loss of jolting when reducing the transmission resistance and going improves driving efficiency, prolongs motor service life; In addition; Vehicle bridge is captiveed joint with the chassis through spring plate holder 6, makes in the spring plate holder 6 of car body gravity near the wheel position, because of spring plate is tried one's best under the situation that does not influence assembling near wheel; Gravity torque is reduced; Gravity passes on the ground through wheel, reduces the influence that back axle receives gravity, makes back axle not fragile; Drum brake system 7 makes brake system more stable.
