Embodiment Construction

[0020] refer to figure 1 , the transmission system of the electric vehicle according to the first embodiment may include a first electric motor 1, an I gear pinion 2, a synchronizer 3, a II gear pinion 4, an I gear bull gear 6, a one-way clutch 7, a main reduction gear 8. The main reduction bull gear 9, the II gear bull gear 10, the auxiliary drive pinion 11 and the second motor 12.

[0021] The first electric motor 1 has a first output shaft, and the first output shaft is provided with an I gear pinion 2 , a synchronizer 3 and a II gear pinion 4 . The I gear pinion 2 and the synchronizer 3 can move synchronously with the first output shaft, and the II gear pinion 4 can move relatively with the first output shaft. For example, the II gear pinion 4 may be provided on the first output shaft through a rolling bearing 5 to move relative to the first output shaft.

[0022] The second motor 12 may be an induction motor, and the second motor 12 may have a second output shaft arrang...
