Abstract
The utility model discloses an electric automobile rear axle drive which comprises a rear axle, a brake disc rotating shaft, a brake line mounting base, a brake shoe component, a brake disc shell, a speed reducer device and a motor, wherein the brake disc rotating shaft is arranged at the two ends of the rear axle; the brake line mounting base is fixedly arranged at the two ends of the rear axle; the brake shoe component is fixedly arranged at the two ends of the rear axle; the brake disc shell is fixedly arranged at the two ends of the rear axle and wraps the brake shoe component; the speed reducer device is fixed in the middle of the rear axle through screws; the speed reducer device is internally provided with a differential mechanism; the output shaft of the motor is connected with the speed reducer device; the motor and the speed reducer device and the rear axle form an integral. The electric automobile rear axle drive has the advantages of freedom of vibration, low noise, simplicity of assembling, large output torque and the like.
Description
Technical field
The utility model is a kind of rear-axle drive, relates in particular to a kind of rear axle of electric automobile and drives, and is applied to the drive system field of electronlmobil.
Background technology
According to the effect difference of vehicle bridge, vehicle bridge can be divided into drive axle, steeraxle, support bridge, steering drive axle, if back axle is exactly drive axle, at this time except carrying effect, also plays and drives and the effect of differential in addition of slowing down.
The rear-axle drive that at present automobile uses not only assembles complexity, have noise and also output torque little.
Utility model content
For solving above-mentioned technological deficiency, the utility model discloses a kind of assemble simple, overall operation is shockproof, low noise, rear axle of electric automobile that output torque is large drive.
The utility model discloses a kind of rear axle of electric automobile drives, comprise: back axle, brake disc turning cylinder, brake cable mount pad, brake shoe assembly, brake disc shell, speed reducer device, motor, described brake disc turning cylinder is arranged on the two ends of back axle, described brake cable mount pad is installed in the two ends of back axle, described brake shoe assembly is installed in the two ends of back axle, described brake disc shell is installed in back axle two ends and is wrapped in brake shoe assembly, described speed reducer device is fixed by screws in the middle part of back axle, and diff is contained in described speed reducer device inside.
Described motor is connected with speed reducer device by motor output shaft, and described motor and speed reducer device, back axle form an entirety.
Owing to adopting technique scheme, the utlity model has following beneficial effect:
1, shockproof, low noise;
2, assembling is simple;
3, output torque is large.
Accompanying drawing explanation
Fig. 1 is the cutaway view that a kind of rear axle of electric automobile of the utility model drives.
Wherein: 1-back axle; 2-brake disc turning cylinder; 3-brake cable mount pad; 4-brake shoe assembly; 5-brake disc shell; 6-speed reducer device; 7-motor.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of rear axle of electric automobile drives, comprise: back axle 1, brake disc turning cylinder 2, brake cable mount pad 3, brake shoe assembly 4, brake disc shell 5, speed reducer device 6, motor 7, described brake disc turning cylinder 2 is arranged on the two ends of back axle 1, described brake cable mount pad 3 is installed in the two ends of back axle 1, described brake shoe assembly 4 is installed in the two ends of back axle 1, described brake disc shell 5 is installed in back axle 1 two ends and is wrapped in brake shoe assembly 5, described speed reducer device 6 is fixed by screws in the middle part of back axle 1, diff is contained in described speed reducer device 1 inside.
Described motor 7 is connected with speed reducer device 6 by motor output shaft, and described motor 7 forms an entirety with speed reducer device 6, back axle 1.
The utility model is so concrete enforcement, the input shaft of motor 7 is connected with speed reduction gearing 6, due to the effect of reductor, the rotating speed of speed reducer device 6 output shafts declines, moment of torsion increases, and this moment is passed to drive wheel by back axle 1, speed reduction gearing 6 contains diff like this in turning simultaneously, can be by adjusting the rotating speed of two tires, reach rational turning effect, the wearing and tearing of tire are avoided, motor 7 and speed reducer device 6, back axle 1 being integrally formed, assemble fairly simple, brake cable mount pad 3, brake shoe assembly 4, the installation of brake disc shell 5 has formed a part for brake system, play brake action.
Finally it should be noted that: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
