Description
Technical field
The utility model relates to a kind of motor, particularly a kind of motor with double output shaft sleeves of differential function, is applicable to the drive system of three-wheel or four-wheel electric motor car.
Background technology
The drive system of existing three-wheel or four-wheel electric motor car is: the high speed traction electric machine slows down with the drive axle master by driving chain or power transmission shaft wheel and differential mechanism is connected, and relies on semiaxis to give driving wheels with transmission of power again.Traction electric machine, driving chain or power transmission shaft suffer the erosion of dust and sand muddy water and occupy bigger space, not compact all in the outside of back axle bag, and complex structure, transmission link be many, reduced transmission efficiency.
Summary of the invention
The technical problems to be solved in the utility model provides a kind ofly to be gathered slowspeed machine and differential mechanism in one, has the motor of the double output shaft sleeves of differential function, is applicable to the drive system of three-wheel or four-wheel electric motor car.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of motor with double output shaft sleeves of differential function comprises casing, stator and rotor; The both sides of its casing electric motor end cap that is located by connecting, the inner ring and the stator of casing are located by connecting; Rotor is made up of differential mechanism and magnetic steel ingot, the both sides of the differential mechanism differential mechanism end cap that is located by connecting; Bearing is equipped with at the middle part of the electric motor end cap of both sides respectively, and the inner ring of bearing cooperates with the shoulder of differential mechanism both sides end cap, and the supporting differential mechanism rotates; The cylindrical location and installation magnetic steel ingot of differential mechanism; The output bevel gear of differential mechanism both sides is connected with jackshaft respectively by spline.
Described stator adopts interference fit to be connected with the inner ring of casing.The cylindrical of described differential mechanism is connected with magnetic steel ingot is gluing.
The beneficial effects of the utility model are:
1. the utility model has omitted main the deceleration to wheel in driving chain in existing three-wheel or the four-wheel electric motor car drive system or power transmission shaft and the drive axle bag, and slowspeed machine, differential mechanism are gathered in a motor case, and differential mechanism is placed in the rotor; Compact conformation, volume are little, for three-wheel or the microminiaturization of four-wheel electric motor car drive system create conditions.
2. the minimizing transmission link has improved transmission efficiency.
3. do not have the exposed drive disk assembly that outside, suffers the erosion of dust and sand muddy water, reduce their maintenance capacity, improved the useful life and the reliability of drive disk assembly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment is shown in Fig. 1-2: a kind of motor, the both sides of its casing 1 electric motor end cap 5 that is located by connecting with double output shaft sleeves of differential function, and the inner ring of casing 1 and stator 2 are located by connecting; Rotor is made up of differential mechanism 4 and magnetic steel ingot 3, and the both sides bolt of differential mechanism 4 connects differential mechanism end cap 9; Bearing 6 is equipped with at the middle part of the electric motor end cap 5 of both sides respectively, and the inner ring of bearing 6 cooperates with the shoulder of differential mechanism both sides end cap 9, and supporting differential mechanism 4 rotates; The cylindrical location and installation magnetic steel ingot 3 of differential mechanism 4; The output bevel gear 10 of differential mechanism 4 both sides is connected with jackshaft 7 respectively by spline.Described stator 2 adopts interference fit to be connected with the inner ring of casing 1.The cylindrical of described differential mechanism 4 and 3 gluing connections of magnetic steel ingot.
The utility model places differential mechanism in the rotor, and slowspeed machine, differential mechanism are gathered in a motor case 1, and electric motor end cap 5 is connected with driving hub 8 bolts of both sides.One end of jackshaft 7 is connected with output bevel gear 10 splines of differential mechanism both sides respectively, and the other end and the driving wheel of jackshaft 7 are in transmission connection.
A kind of novel narrow body fore and after double three-wheeled electric vehicle, its car body can be swung relatively with rear driving axle, so that when the travels down of bend or uneven, keeps the stability of passenger's body center of gravity; Its width only has 61cm, and the front and back wheel wheelbase has only 141cm; Traditional high speed traction electric machine slows down with the drive axle master by driving chain or power transmission shaft wheel and differential mechanism is connected, and relies on semiaxis to give the transmission scheme of driving wheels with transmission of power again, is difficult to satisfy so compact width and wheelbase.The utility model is gathered slowspeed machine, differential mechanism in a motor case (1), and differential mechanism is placed in the rotor; Compact conformation, volume are little; Be the research and development of novel narrow body fore and after double three-wheeled electric vehicle, small and exquisite key drive disk assembly is provided.
