Car semiaxis is connected by spline fitted.
Further, motor includes output shaft, and output shaft end is provided with spline, for connecting with splined driveshaft
Connect.
Further, output shaft end is arranged to external splines.
Further, motor and single-stage speed reducing case coordinate installation blending bolt affixed by seam.
Further, motor, single-stage speed reducing case, electric machine controller are provided with the cooling water channel communicated.
Further, electric machine controller is bolted with single-stage speed reducing case.
Integrated system of the present invention has the beneficial effect that：
1st, motor, single-stage speed reducing case and electric machine controller directly dock in integrated system of the present invention, reduce
Space occupancy, make the arrangement of engine cabin more reasonable, orderly, attractive in appearance.
2nd, the triple line that motor connects with electric machine controller in integrated system of the present invention is arranged on single-stage speed reducing
In punch-out equipment shell, improve the space availability ratio of engine cabin, and reduce triple line it is long caused by electromagnetic interference.
3rd, integrated system of the present invention is integrally disposed by single reduction gear, differential mechanism, makes whole driving system structure tight
Gather, save space.
4th, integrated system of the present invention can meet basic use demand using the transmission of single-stage speed reducing case, and reduce into
This, improves reliability and stability.
5th, the setting that integrated system of the present invention is communicated by cooling water channel, a cooling system is shared, saves space.
