Protect, it is light the characteristics of, and cost of use is relatively low, is more and more taken seriously.
Using motor existing rear drive axle of electric motor more, two stage reducer, the drive mechanism of differential mechanism, driving-chain compared with
Long, structure arrangement is not compact enough so that vehicle transmission efficiency is low, is not particularly suited for mini electric vehicle and uses.
Accordingly, it would be desirable to be improved to existing electric car driving back axle, using first stage decelerator, to first stage decelerator
Driving and driven gear shaft carries out cold-extruded and forces down number of teeth processing, improves transmission efficiency, makes structure compacter.
The content of the invention
It is in order to solve the above problems, to devise a kind of electric car driving back axle in the purpose of this utility model.Specifically set
Meter scheme is：
A kind of electric car drives back axle, mainly includes：Motor, reduction box, motor is passed through between the motor and reduction box
Output gear shaft is connected, and the motor output gear axle is through the reduction box and is connected with one-level driven gear, the one-level
Driven gear is connected by bolt with differential carrier, is connected with rear axle case below the reduction box, the rear axle case with
Driving axle housing is provided between the reduction box, the quantity of the driving axle housing is located at the left and right of the rear axle case for two respectively
Both sides, the upper end of the driving axle housing is connected by bolt with the reduction box, the lower end of the driving axle housing by bolt with
Through there is jack shaft in the rear axle case connection, the driving axle housing, the inner side top of the reduction box is fixed with semiaxis
Gear, the jack shaft is connected by axle shaft gear with planetary gear.
Connected between the motor and the differential mechanism by first stage decelerator, the driving and driven tooth of the first stage decelerator
Wheel is respectively the motor output gear axle and one-level driven gear.
The motor output gear axle and the one-level driven gear are all bevel gear, where the motor output gear axle
Axis is vertical with the jack shaft axis, and the center of gravity of motor shaft and one-level driven gear is nearer apart.
The motor output gear axle and the high intensity bevel gear that one-level driven gear is all that cold extrusion is processed, transmission
Than for 12.
The beneficial effects of the utility model are：
Electric car of the present utility model drives back axle, and power directly is input into differential mechanism, simple and compact for structure, due to contracting
Short driving-chain, improves transmission efficiency；Motor output gear axle center of gravity, at a distance of relatively near, is driven more with first stage decelerator center of gravity
It is stable, it can avoid being driven interference caused by vibration to a certain extent.After the electric car driving that the utility model is provided
It is may be directly applied to after bridge formation product on electric car, while traffic safety is ensured, make full use of motor power, reach
The effect of energy-conserving and environment-protective.
