The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Extremely shown in Figure 9 as Fig. 1.Automobile-used motor 2 is the automobile frequency control motor, can be the Thee-phase alternating current permanent-magnetic synchronous dynamo, also can adopt ac three-phase asynchronous motor, as being YCVF the series automobiles asynchronous or permanent-magnet synchronous traction electric machine of variable-frequency speed-regualting triphase.
Change speed gear box (1) is many grades of speed-changing gear boxs.Change speed gear box 1 adopts the matrix housing, does not have end cap by automobile-used motor 2 front end cover adjacents, directly is fixed on automobile-used motor 2 front end covers by its edge.Saved power-transfer clutch between automobile-used motor 2 and the change speed gear box 1.Change speed gear box 1 is provided with two cylinders 30, promotes shift fork, and gear shift is used.Automobile-used motor 2 output shafts 27 are change speed gear box 1 input shaft 27.Electric machine stand mouth and motor front end cover are made one, have promptly cancelled the left end cap of motor among the patent application CN200910061844, the direct and motor output end assembling of change speed gear box.
