Abstract
The utility model relates to a permanent brushless direct-current speed reduction motor of an electric vehicle, which comprises a permanent brushless direct-current motor and a speed reducer, wherein the permanent brushless direct-current motor and the speed reducer which are coupled with each other are integrally connected. The permanent brushless direct-current speed reduction motor has compact and reasonable structure and small volume of powertrain, saves space, consumes low power, has high transmission efficiency during a power transmission process, and has larger torque and stronger driving capacitor compared with the equivalent permanent brushless direct-current motor.
Description
Affiliated technical field
The utility model relates to a kind of motor, and especially motor and reductor all-in-one-piece are specially adapted to the DC permanent-magnetic brushless reducing motor on the electric automobile.
Background technology
Present known oil electric mixed dynamic automobile, pure electric automobile adopt permanent-magnet brushless DC electric machine as power more, improve moment of torsion, further improve the permanent magnet brushless dc driveability, just must be combined with the size of reduction box or increasing permanent-magnet brushless DC electric machine, the automobile overall dimensions is strengthened, and cost improves.
Summary of the invention
The purpose of this utility model be to overcome the weak point in the background technology and provide a kind of can be under the situation that does not change original permanent magnet brushless DC motor structure, fuse with reductor and improve the electric automobile DC permanent-magnetic brushless reducing motor of the moment of torsion of motor and driveability, compact conformation.
The technical scheme that its technical problem that solves the utility model adopts is: permanent-magnet brushless DC electric machine and reductor assembly link into an integrated entity, and make the coupling of permanent-magnet brushless DC electric machine and decelerator; The one-level driving gear of decelerator is connected with the main shaft of permanent-magnet brushless DC electric machine and fixes on it, one-level driving gear and the engagement of one-level driven gear, the one-level driven gear is connected with the secondary driving gear is coaxial, secondary driving gear and extreme gear often mesh, decelerator is a double reduction, speed reducing ratio is identical, and module is identical, has constituted electric machine main shaft and power output shaft on same axis.
The utility model compared with prior art has following advantage:
1, be the electric vehicle structure compact and reasonable of power with the utility model, dwindled power assembly volume, saved the space, reduced cost, need not to be provided with clutch and gearbox;
2, more equal permanent-magnet brushless DC electric machine torque is big, driving force is strong.
