Through the retrieval of prior art is found that Chinese patent application publication number CN104295675A applies for publication date
2015.01.21, one " a kind of two grades of electric vehicle transmission assemblies " is described.A kind of two grades of electric motor cars of this disclosure of the invention become
Speed device assembly, defeated with motor equipped with power shaft and jackshaft, power shaft in the inner chamber formed after left box body and right case mould assembling
Shaft connects, and one grade of gear on jackshaft often engages with one grade of axle teeth portion of power shaft, and intermediate gear and two grades of axle teeth portion are normal
Engagement；Being set with synchronizer gear sleeve on one grade of jackshaft between gear and intermediate gear, synchronizer gear sleeve can dialling at shift fork
Along jackshaft axial slip under Dong；The reduction gearing portion of jackshaft often engages with the reduction gearing on reducing gearbox, planetary gear
Axle is fixed on reducing gearbox, and two planetary gears on planetary gear axle often engage with two output bevel gears simultaneously, and these are two years old
The angular wheel shaft of individual output bevel gear is respectively supported in the installing hole of reducing gearbox left end and right-hand member.This invention can be by motor
Power is exported by the angular wheel shaft of output bevel gear, and angular wheel shaft can be made to have two gears by gearshift.Although it is above-mentioned
Patent application provides a kind of change speed gear box and has two gears, but it still exists electric motor car list motor and drives, and motor is efficient
Working range is narrower, it is difficult to meet the car load requirement under different operating mode, different rotating speeds, and existing gear shift mechanism structure is relatively
For complicated, the shifting time is longer, it is difficult to meet crash change of speed and ride comfort requirement.
