[0038] The schematic diagram of the drive train structure of a 7.5-ton pure electric garbage transfer vehicle is as follows: image 3As shown, the driving motor 1 is connected to the manual gearbox 3 through the clutch 2, and the output torque of the motor is transmitted to the rear wheels 7 via the transmission shaft 5 and the drive axle 6 to drive the vehicle. The clutch is controlled by the driver operating the clutch pedal. The signals needed to determine the working state of the clutch are: 1. Vehicle speed signal; 2. Actual speed signal of the driving motor; 3. Neutral gear signal; 4. Reverse gear signal. In addition, the parameters that need to be clarified include the reduction ratio of each gear of the gearbox, the main reduction ratio of the reducer, and the diameter of the tire. In this example, the reduction ratios of the five forward gears are 5, 2.5, 1.5, 1, 0.8, the reverse gear ratio is 4.4, the main reduction ratio is 5.286, and the tire diameter is 0.755m. ...
