Abstract
The invention discloses an electric automobile rear axle drive. The electric automobile rear axle drive comprises a rear axle, brake disc rotating shafts, brake cable installation bases, brake shoe assemblies, brake disc outer shells, a speed reducer device and a motor. The brake disc rotating shafts are arranged at the two ends of the rear axle, the brake cable installation bases are fixedly arranged at the two ends of the rear axle, the brake shoe assemblies are fixedly arranged at the two ends of the rear axle, the brake disc outer shells are fixedly arranged at the two ends of the rear axle and wrap the brake shoe assemblies, the speed reducer device is fixed to the middle of the rear axle through a screw, a differential mechanism is contained inside the speed reducer device, the motor is connected with the speed reducer device through a motor output shaft, and the motor, the speed reducer device and the rear axle form a whole. The electric automobile rear axle drive has the advantages of being free of vibration, low in noise, easy to assemble, large in output torque and the like.
Description
Technical field
The present invention 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
Different according to the effect 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.
Summary of the invention
For solving above-mentioned technological deficiency, the invention discloses a kind of assemble simple, overall operation is shockproof, low noise, rear axle of electric automobile that output torque is large drive.
The invention 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 integral body.
Owing to adopting technique scheme, the present invention 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 present invention 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 invention 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 integral body with speed reducer device 6, back axle 1.
The present invention is so concrete enforcement, the input shaft of motor 7 is connected with speed reduction gearing 6, effect due to 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 when turning simultaneously, can be by adjusting the rotating speed of two tires, reach rational turning effect, the wearing and tearing of tire have been 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, played brake action.
Finally it should be noted that: above embodiment is only in order to illustrate the present invention and unrestricted technical scheme described in the invention; Therefore, although this specification sheets has been described in detail the present invention 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 present invention; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in claim scope of the present invention.
Claims (2)
