The clutch 8 adopts an electromagnetic clutch, and the left end and the right end of the clutch 8 are respectively connected with the middle shaft I6 and the middle shaft II 13.
The synchronizer 10 is disposed between the first-gear driven gear 9 and the second-gear driven gear 11, and the synchronizer 10 is axially movable and coupled to the first-gear driven gear 9 and the second-gear driven gear 11, respectively.
The transmission ratio between the auxiliary gear driving gear 3 and the auxiliary gear driven gear 7 is smaller than the transmission ratio between the second gear driving gear 5 and the second gear driven gear 11.
The working principle of the invention is as follows:
a neutral gear state: the synchronizer 10 is placed in the neutral position and the clutch 8 is disengaged, with the transmission in neutral.
A first gear state: the synchronizer 10 is moved to be engaged with the first-gear driven gear 9, the clutch 8 is in a disengaged state, the transmission is in the first gear, and the output torque of the driving motor 1 is transmitted to the intermediate ii shaft 13 through the first-gear driving gear 4 and the first-gear driven gear 9.
