Description

Electric vehicle brushless DC speed reduction motor
Technical field
The utility model relates to dynamo-electric field, relates in particular to a kind of reducing motor, specifically refers to a kind of electric vehicle brushless DC speed reduction motor.
Background technology
At present in electric automobile field, its motor used is generally motor and adds the combination of turbine reduction box or the combination that motor adds 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.
Utility model content
The technical problems to be solved in the utility model is to provide the electric vehicle brushless DC speed reduction motor that a kind of new volume is little, transmission efficiency is high.
The technical solution of the utility model 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 integral type structure, and described sun gear and motor output shaft are 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.
Adopt after such scheme, 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 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 utility model 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.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of electric vehicle brushless DC speed reduction motor of the present utility model is described in detail below:
As shown in Figure 1, a kind of electric vehicle brushless DC speed reduction motor, electric vehicle brushless DC speed reduction motor, comprise DC brushless motor 1 and planetary reducer 2, described DC brushless motor 1 is provided with front end housing 1.1 and motor output shaft 1.2, described planetary reducer 2 comprises sun gear 2.1, ring gear 2.2, is located at planetary gear 2.3 and connection cover 2.4 on planet carrier, described front end housing 1.1, ring gear 2.2 and connection cover 2.4 are integral type structure, and described sun gear 2.1 is integral type structure with motor output shaft 1.2.In the present embodiment, the quantity of described planetary gear 2.3 is three.
In the above-described embodiments, only the primary structure of DC brushless motor is explained, in the specific implementation, described DC brushless motor is also equipped with controller 1.3 and transducer 1.4, because it is prior art and there is no direct relation with the technical problem to be solved in the present invention, so the concrete structure of this part is repeated no more.
Below by reference to the accompanying drawings best embodiment of the present utility model is described; but these explanations can not be understood to limit scope of the present utility model; obviously; under design of the present utility model; still can make a lot of variations; as as described in the quantity of planetary gear also can be four or more etc., this explanation especially, any any change of making under inventive concept of the present utility model all will fall in protection range of the present utility model.
