Abstract
The invention relates to a transmission system of an electric vehicle with a novel structure, which comprises a driving motor I, a gear shifting clutch, an AMT (Automated Mechanical Transmission) transmission, a one-way clutch, a driving motor II and the like. The driving motor II is connected with a differential assembly of the AMT transmission through the one-way clutch. When the gear shifting clutch works, power input to the AMT transmission by the driving motor I is interrupted and a finished automobile TCU (the control unit) sends a command that the power is directly provided for the differential assembly of the AMT transmission by the driving motor II so as to realize that the finished automobile power is not uninterrupted in the process of shifting gears. The driving motor I and the gear shifting clutch are arranged outside a box body of the AMT transmission. The one-way clutch and the driving motor II are integrated in the box body of the AMT transmission. The transmission system has simple and compact structure and good integral performance, is easy to manufacture and control and has high reliability. Due to the application of the power transmission system of the AMT electric vehicle, the finished automobile performance of the electric vehicle is greatly improved and the effect similar with a double clutch transmission can be realized. However, the cost and the control complex degree of the transmission system are much lower than those of the double clutch transmission, the requirement of the AMT electric vehicle on the performance of the motor is lower than that of a conventional single reduction pure electric vehicle, and the transmission system can be popularized and applied in a large scale.
