The transmission can produce different transmission ratios between the engine and the wheels during the driving of the vehicle. By shifting gears, the engine can work in its best power performance state. The development trend of transmission is more and more complex, and the degree of automation is higher and higher. Automatic transmission will be the mainstream in the future. effect The output speed of the engine is very high, and the maximum power and torque appear in a certain speed range. In order to give full play to the best performance of the engine, there must be a set of transmission device to coordinate the speed of the engine and the actual running speed of the wheels. function ① Change the transmission ratio and expand the variation range of driving wheel torque and speed to adapt to frequently changing driving conditions, and make the engine work under favorable working conditions (high power and low fuel consumption); ② When the rotation direction of the engine remains unchanged, the vehicle can travel backwards; ③ Use neutral gear to interrupt power transmission, so that the engine can start and idle, and facilitate transmission shift or power output. The transmission is composed of a variable speed transmission mechanism and a control mechanism. When necessary, a power take-off can also be added. There are two ways to classify: according to the change mode of transmission ratio and according to the difference of operation mode. advantage Shift gears with the goal of reducing fuel consumption. Always use the maximum power of the engine. All driving conditions have corresponding shift points. Shift points change arbitrarily.
