Abstract
The utility model relates to an electric car driving device, aiming at providing an electric car driving device with simple structure and high driving efficiency and free from maintenance. The technical scheme realizing the purposes of the utility model is as follows: the electric car driving device comprises two wheel hub motors, wherein the wheel hub motors are outer rotor brushless permanent magnetic motors and are respectively installed in two rear wheel rims of the electric car, and the outer rotors of the wheel hub motors are fixedly connected or assembled with the wheel rims; the driving device further comprises motor shaft sleeve modules sheathed on two motor shafts and a rear shaft; the motor shaft sleeve modules comprise housings and connecting blocks on the housings; the housings are sheathed on the motor shafts of the wheel hub motors and are fixedly connected with the motor shafts via nuts; and the connecting blocks are welded and connected with the rear shaft.
Description
Technical field
The utility model relates to a kind of electronlmobil, particularly a kind of actuating device of electronlmobil.
Background technology
The actuating device of present domestic electronlmobil, the main integral type that adopts brush motor to drive has the back axle form of diff and speed reduction gearing, its structure is the middle part that brush motor is located at back axle, the output of brush motor is connected with diff with speed reduction gearing, the rotation of driving automobile back wheel, this structure forms an outstanding big bag, the ground Clearance of having lowered car load at the back axle middle part.Brush motor efficient is not as brushless motor in addition, and brush motor needs to keep in repair cumbersome with changing carbon brush in the motor after using 2 years.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provides a kind of simple in structure, the high and non-maintaining electric automobile driving apparatus of drive efficiency.
The technical scheme that realizes the utility model purpose is, electric automobile driving apparatus comprises two wheel hub motors, and described wheel hub motor is the external rotor brushless magneto-electric machine, be contained in respectively in two rear rims of electronlmobil, the wheel hub motor outer rotor is captiveed joint with wheel rim or is integrated; Described actuating device also comprises and is set in two motor shaft sleeve assembly and rear axles on the motor shaft, described motor shaft sleeve assembly comprises overcoat and the contiguous block that puts outward, overcoat is enclosed within on the motor shaft of wheel hub motor, and captive joint with nut with motor shaft, contiguous block and rear axle are welded to connect.
Need not diff and speed reduction gearing in the utility model, be welded by motor shaft sleeve assembly and a rear axle between two motors, make back axle become simple and reliable.Wheel hub motor directly drives the wheel running, has simplified design, has improved efficient.
Description of drawings
Fig. 1 is the utility model embodiment 1 electric automobile driving apparatus structural representation
The specific embodiment
Be described further below in conjunction with embodiment.
Embodiment 1
