Technical field
The utility model 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.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, provides the motor of integrated deceleration and box of tricks, by decelerator, differential mechanism and motor integration Integrated design, to realize that drive part is 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 utility model is that the technical solution problem adopts following technical scheme:
The version of the motor of the integrated deceleration of the utility model 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 the frame that spreads out of rotation for driving the rotation of described differential mechanism by described planetary gear, 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 utility model 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 the circumference symmetry.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model, by 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 utility model, decelerator is that circumferencial direction around the motor output shaft axle head is uniformly distributed gear, stressed direction circumference symmetry, drive part is stressed evenly, motor is directly installed on axle housing, and whole drive axle is without unbalance loading, each parts are not subject to unnecessary torsion, and the car load ride comfort is better;
3, the integrated setting of the utility model, its vibration is little, noise is low, energy-conservation height, superior performance.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model motor output shaft and subtract the bundle device and coordinate schematic diagram.
Number in the figure: 1 first semiaxis; 2 electric machine casings; 3 rotors; 4 stators; 5 motor shafts; 6 decelerators; 7 planetary gears; 8 framves that spread out; 9 differential mechanisms; 10 second semiaxis.
Embodiment
Referring to Fig. 1, in the present embodiment, the version of the motor of integrated deceleration and box of tricks is: integrated electric machine assembly, decelerator 6 and the differential mechanism 9 of arranging, by electric machine casing 2, stator 4, rotor 3 and motor shaft 5 form electric machine assembly, the hollow shaft of motor shaft 5 for running through vertically is set, output at motor shaft 5 connects firmly an output gear, planetary gear 7 in decelerator 6 is to be meshed with the output gear of motor shaft 5, drive the frame 8 that spreads out of rotation for driving the rotation of differential mechanism 9 by planetary gear 7, the first semiaxis 1 and the second semiaxis 10 that are connected to the two ends of differential mechanism 9 are for coaxial with motor shaft 5, and the first semiaxis 1 runs through and extends in motor shaft 5, take the first semiaxis 1 and the second semiaxis 10 is jack shaft, the first semiaxis 1 is fixedly connected with the bevel gear at differential mechanism two ends respectively with the second semiaxis 10.
In concrete enforcement, the axle head circumferencial direction that each planetary gear 7 in decelerator 6 is set is around motor shaft 5 is uniformly distributed, and the circumference symmetry.In the present embodiment, four planetary gears 7 are arranged on the frame 8 that spreads out, and four planetary gears 7 are distributed on the circumference of motor shaft 5, and the output gear connected firmly with the motor shaft output is meshed.
The rotation of motor shaft 5 is transmitted and is caused the frame 8 that spreads out by planetary gear in decelerator 7, drives differential mechanism 9 with this, and then makes the first semiaxis 1 and the second semiaxis 10 become jack shaft.
