Motor 1 can be AC alternating current dynamo, switched reluctance machines, direct current permanent magnet motor or the like, and those skilled in the art can select suitable motor model and power as required.
Change speed gear box can be divided into manual, automatic two kinds, and Manual transmission mainly is made up of gear and axle, produces the speed change bending moment by different gear combination; And Automatic Transmission AT is made up of hydraulic torque converter, planetary wheel and hydraulic control system, and the mode by fluid power transmission and gear combination reaches the speed change bending moment.The general utility functions of change speed gear box are: one, change transmitting ratio; Two, under the constant situation of propulsion source hand of rotation, vehicle can be fallen back travel; Three, utilize neutral, interrupt transmission of power, and be convenient to shifting of transmission or carry out takeoff output.
Change speed gear box 5 can adopt various suitable gearbox-type as required, and the gear of change speed gear box 5 also can be selected as required.In addition, because the propulsion source of drive system of electric motor vehicle of the present utility model is a motor 1, can realize reverse gear by 1 counter-rotating of control motor, therefore need not to be provided with reverse gear in the change speed gear box 5, help simplifying the structure of change speed gear box 5, reduce the size and the weight of change speed gear box 5, help improving the performance of vehicle.
The main effect of drop-gear box 2 is the power that propulsion source is exported to be slowed down to increase turn round, i.e. the power of propulsion source output will be through underspeeding after the drop-gear box 2 and improving moment of torsion.The transmitting ratio of drop-gear box 2 can carry out choose reasonable as required.
According to a kind of embodiment of the present utility model, further, as shown in Figure 1, drop-gear box 2 comprises input shaft 7 and output shaft 8, connect by gear pair between the input shaft 7 of drop-gear box and the output shaft 8, the output shaft of motor 1 is connected with the input shaft of drop-gear box 7, and the output shaft 8 of drop-gear box is connected with change speed gear box 5 by power-transfer clutch 3.
Connect by the one-level gear pair between the input shaft 7 of drop-gear box and the output shaft 8, thereby those skilled in the art can also be provided with two-stage or the secondary transmitting ratio that increases drop-gear box 2 of multi-stage gear as required.
Further, drop-gear box 2 also comprises flywheel 4, and the output shaft 8 of drop-gear box is connected with power-transfer clutch 3 by flywheel 4.
One end of the output shaft 8 of drop-gear box is captiveed joint with flywheel 4, as passes through bolted connection.Flywheel 4 is also captiveed joint with power-transfer clutch 3, captives joint with power-transfer clutch 3 by bolt as flywheel 4.
