Description
Technical field
The utility model is related to electric car, more particularly to a kind of speed reducer for electric vehicle.
Background technology
Speed reducer for electric vehicle is connection motor and drive shaft device, traditional decelerator, as shown in figure 1, input shaft
Connect in motor, cage and be fixedly connected with semiaxis, because semiaxis is each attached to cage, the semiaxis of both sides is all fixed
, if traveling is having a wheel run-off the straight, whole drive axle all can run-off the straight, the comfortableness and operation peace of electric car
Full property is poor, and some present brake of electric vehicle poor performances.
Utility model content
The applicant is directed to disadvantage mentioned above, and having carried out Improvement, there is provided a kind of speed reducer for electric vehicle.
The technical scheme that the utility model is used is as follows：
A kind of speed reducer for electric vehicle, decelerator main body, the decelerator main body upper end rotates connection input shaft, the input
Axle can be connected can connect on motor, the other end integrally connected input shaft extension of input shaft, the input shaft extension
Electromagnetic brake, the decelerator main body lower end sets differential mechanism, and the decelerator main body is located at differential mechanism both sides and sets fixation
End cap, the end cap rotates connection output shaft by bearing, and described output shaft one end is fixed in differential mechanism, and the other end opens up company
The connecting hole that electric car drives cage is connect, driving cage connects Electricmotor car wheel by semiaxis.
It is used as the further improvement of above-mentioned technical proposal：
It is located at providing holes back-up ring on the outside of bearing in the end cap, oil sealing is also set up between end cap and output shaft.
Oil sealing bushing is arranged on the input shaft extension, oil is also provided between the oil sealing bushing and decelerator main body
Envelope.
The beneficial effects of the utility model are as follows：The speed reducer for electric vehicle, the electromagnetism connected by input shaft extension
Brake, can be used as parking braking or service brake, improve the braking ability of electric car, and the differential mechanism connection of decelerator
Output shaft, electric car drives cage to be fixed to by steady pin on output shaft, and driving cage can be done necessarily around the axis of output shaft
The angular swing of amplitude, realizing the two ends wheel of driving cage connection can independently swing, when one end wheel chance hole declines or meets convex
Body sway will not significantly be caused during lifting, the comfortableness and processing safety of electric car is improved.

Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is illustrated.
As shown in Fig. 2 the speed reducer for electric vehicle of the present embodiment, decelerator main body 1, the upper end of decelerator main body 1 rotates connection
Input shaft 2, input shaft 2 can connect motor, the other end integrally connected input shaft extension 21 of input shaft 2, and input shaft prolongs
Stretch and oil sealing bushing 22 is arranged in section 21, be also provided between oil sealing bushing 22 and decelerator main body 1 on oil sealing, input shaft extension 21
Electromagnetic brake 3 can be connected, the lower end of decelerator main body 1 sets differential mechanism 4, and decelerator main body 1 passes through spiral shell positioned at the both sides of differential mechanism 4
Bolt fixes end cap 5, and end cap 5 is rotated by bearing is located at providing holes back-up ring 51 on the outside of bearing, end in connection output shaft 6, end cap 5
Oil sealing is also set up between lid 5 and output shaft 6, the one end of output shaft 6 is fixed in differential mechanism 4, the other end opens up connection electric car and driven
The connecting hole 61 of dynamic cage, driving cage connects Electricmotor car wheel by semiaxis.
The speed reducer for electric vehicle connects motor in use, be connected on the axle housing of drive axle by input shaft 2,
Input shaft extension 21 connects electromagnetic brake 3, and the electromagnetic brake 3 can be used as parking braking or service brake, institute
State output shaft 6 drives cage rotation to be connected by steady pin and electric car, and motor can driving electric car by decelerator
The rotation of cage is driven, electric car drives cage to drive two ends vehicle wheel rotation by semiaxis, and driving cage can be around output shaft
Axis does the angular swing of certain amplitude, realizes the two ends wheel of driving cage connection and can independently swing, meets and cheat when one end wheel
Decline or will not significantly cause body sway when meeting convex lifting, improve the comfortableness and processing safety of electric car.
Above description is explained of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope is referring to claim, and in the case of without prejudice to basic structure of the present utility model, the utility model can make any shape
The modification of formula.
