Abstract
The invention discloses a motor integrated with a reducing and differential mechanism, which is characterized in that a motor component, a reducer and a differential are integrated; a motor shaft in the motor component is arranged as a hollow shaft penetrating in the axial direction; the output end of the motor shaft is fixedly connected with an output gear; a planetary gear in the reducer is meshed with an output gear of the motor shaft; a rotating truss is driven by the planetary gear to drive the differential to rotate; a first half shaft and a second half shaft, respectively connected to two ends of the differential, are coaxial with the motor shaft; the first half shaft penetrates the motor shaft and extends out of the motor shaft. The motor has the advantages that no unbalance loading phenomenon of a drive part is achieved, the drive part is stressed by surplus torque, is uniform in stress, small in vibration, low in noise, saves energy, is reliable, and high in overload bearing capacity, effectively saves the chassis space of the finished automobile, reduces the weight, and improves the assembly efficiency.
Description
Technical field
The present invention relates to the motor of a kind of integrated deceleration and box of tricks.
Background technology
Along with the Global Auto recoverable amount further strengthens, the problems such as energy crisis, environmental pollution and global warming become increasingly conspicuous, and new-energy automobile, especially electric automobile become the emphasis of domestic and international motor corporation development.No matter from environmental angle or energy angle, following electric motor car all needs to have a large development, and its exploitation will be related to the ups and downs of numerous industry, may become following new growth engines.In China, electric automobile more has unique market, and metropolis all ubiquity very serious traffic problems and motor vehicle exhaust emission pollution problem.As the daily vehicles of a kind of small-sized, middling speed and short distance, electric motor car is very good.
Conventional electric automobile in the market, its drive motors is all parallel or at right angle setting with decelerator and differential mechanism, there is biasing problem in arrangement, causes following open defect:
1, each parts all will be subject to unnecessary moment of torsion;
2, take up room greatly;
3, the assembly integrated level is low, and quality is excessive, and inconvenience is installed;
4, affect the flexibility index of car load.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, provides the motor of integrated deceleration and box of tricks, with decelerator, differential mechanism and motor integration Integrated design, to realize drive part without unbalance loading, be not subject to unnecessary moment of torsion, drive part is stressed evenly, vibrate little, noise is low, and energy-conservation height is reliability and durability, bear overload capacity high, effectively saved space, car load chassis, weight reduction, improve efficiency of assembling.
The present invention is that the technical solution problem adopts following technical scheme:
The version of the motor of the integrated deceleration of the present invention and box of tricks is: integrated electric machine assembly, decelerator and the differential mechanism of arranging; Form described electric machine assembly by electric machine casing, stator, rotor and motor shaft, the hollow shaft of described motor shaft for running through vertically is set, output at described motor shaft connects firmly an output gear, planetary gear in described decelerator is to be meshed with the output gear of described motor shaft, drive by described planetary gear the frame that spreads out that rotates and be used for driving the rotation of described differential mechanism, the first semiaxis and the second semiaxis that are connected to the two ends of described differential mechanism are to be coaxial with motor shaft, and described the first semiaxis runs through and extends in motor shaft.
The version of the motor of the integrated deceleration of the present invention and box of tricks also is: the axle head circumferencial direction that each planetary gear in described decelerator is set is around motor shaft is uniformly distributed, and circumference is symmetrical.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention, with the integrated setting of decelerator, differential mechanism and motor, improves the part integrated level high, takes up room, is conducive to chassis and arrange;
2, in the present invention, decelerator is that circumferencial direction around the motor output shaft axle head is uniformly distributed gear, stressed direction circumference is symmetrical, and drive part is stressed evenly, motor is directly installed on axle housing, and whole drive axle is without unbalance loading, each parts are not subjected to unnecessary torsion, and the car load ride comfort is better;
3, the integrated setting of the present invention, its vibration is little, noise is low, energy-conservation height, superior performance.
