Abstract
The invention provides a direct current brushless gear motor for an electric vehicle. The direct current brushless gear motor comprises a direct current brushless motor (1) and a planetary reducer (2). A front end cover (1.1) and a motor output shaft (1.2) are arranged in the direct current brushless motor (1). The planetary reducer (2) comprises a sun wheel (2.1), an inner gear ring (2.2), a planetary wheel (2.3) and a connecting cover (2.4), wherein the planetary wheel (2.3) and the connecting cover (2.4) are arranged on a planetary frame, the front end cover (1.1), the inner gear ring (2.2) and the connecting cover (2.4) are of an integrated structure, and the sun wheel (2.1) and the motor output shaft (1.2) are of the integrated structure. The direct current brushless gear motor for the electric vehicle has the advantages of being small in size and high in transmission efficiency.
Description
Technical field
The present invention relates to dynamo-electric field, relate in particular to a kind of reducing motor, specifically refer to a kind of electric vehicle brushless DC speed reduction motor.
Background technology
At present in the electric automobile field, its motor used is generally motor and adds the combination of turbine reduction box or the combination that motor adds the eccentric speed reduction case, and its volume is larger, and transmission efficiency is lower; For reducing the volume of drive motors, also someone adopts planetary reducing motor as driving power, but produces respectively and assemble because motor part and reduction box partly have, and operation is more, and for the volume aspect that reduces motor, effect is very limited.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of new electric vehicle brushless DC speed reduction motor that volume is little, transmission efficiency is high.
Technical scheme of the present invention is, a kind of DC brushless motor and planetary reducer of comprising is provided, described DC brushless motor is provided with front end housing and motor output shaft, described planetary reducer comprises sun gear, ring gear, is located at planetary gear and connection cover on planet carrier, described front end housing, ring gear and connection cover are the integral type structure, and described sun gear and motor output shaft are the integral type structure.
As preferably, the quantity of described planetary gear is at least three.
As preferably, the quantity of described planetary gear is four.
After adopting such scheme, at first sun gear and motor shaft are integrated, and can significantly improve the assembly precision of reducing motor; Secondly, protecgulum and the ring gear of motor are integrated, and can further reduce the volume of motor; Moreover, common planetary gear speed-reduction is that the one-level sun gear is independently, he will connect with motor shaft, and ring gear is also independently in addition, and it will connect with the front end housing of motor by connecting cap, the present invention is that protecgulum, connecting cap, ring gear are integrated, save two places and connected, further dwindled the volume of motor, can greatly improve the assembly precision of reducing motor, reduce frictional dissipation, improved the transmission efficiency of motor.
