Embodiment
The utility model 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 machine, 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.
Gearbox (1) is many grades of speed-changing gear boxs.Gearbox 1 adopts the matrix housing, does not have end cap by automobile-used motor 2 front end housing adjacents, directly is fixed on automobile-used motor 2 front end housings by its edge.Saved clutch between automobile-used motor 2 and the gearbox 1.Gearbox 1 is provided with two cylinders 30, promotes shift fork, and gear shift is used.Automobile-used motor 2 output shafts 27 are gearbox 1 power shaft 27.Electric machine stand output and motor front end housing are made one, have promptly cancelled the left end cap of motor among the patent application CN200910061844, the direct and electric machine stand output assembling of gearbox.
