Place, meanwhile, shifting drum 308 drives P gear park pawl 310 to unclamp output shaft master and subtract gear 205, and output shaft 201 is loose
Open and can rotate.Now start and drive motor 40, drive motor 40 then band driven input shaft 101 and 1 gear driving gear 102 turns
Dynamic, 1 gear driving gear 102 then drives 1 gear driven gear 202 to rotate, and then is kept off lock unit by 1 gear driven gear 202 and 1/2
The meshing relation of 204, it is possible to drive output shaft 201 to rotate, the most just driven output shaft master to subtract gear 205 and rotated, with output shaft
The main differential assembly 50 subtracting gear 205 engagement brings into operation, and electric automobile gear device is in 1 gear running status.
When requiring transformation into 2 gear (when 1 gear changes 2 gear into), now shifting motor 302 drives shifting drum 308
Rotate, and driven 1/2 gear selector fork 309 to move (left side shown in Fig. 2 to 2 gear driven gear 203 directions by shifting drum 308
Mobile), 1/2 gear selector fork 309 then drives 1/2 gear lock unit 204 to move to the left, and nibbles with 2 gear driven gear 203 phases
Closing, drive motor 40 then band driven input shaft 101 and 2 gear driving gear 103 to rotate, 2 gear driving gears 103 drive 2 gears driven
Gear 203 rotates, due to the meshing relation of 2 gear driven gear 203 and 1/2 gear lock units 204, it is possible to drive output shaft 201 turns
Dynamic, the most just drive output shaft master to subtract gear 205 and rotated, subtracted the differential assembly 50 that gear 205 engages with output shaft master and start
Running, electric automobile gear device is in 2 gear running statuses.
In like manner, the above-mentioned electric automobile gear device of the present embodiment can carry out the conversion between 1 gear and 2 gears, and then can
Improve the efficient working range driving motor 40, and can realize quick and precisely shifting gears, it is ensured that traffic safety.
Obviously, the above embodiment of the present invention is only used to understand explanation example of the present invention, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, the most also may be used
To make other changes in different forms.Here without also cannot all of embodiment be given exhaustive.All at this
