Automobile transmission is a set of transmission devices used to coordinate the rotation speed of the engine and the actual driving speed of the wheels, and is used to exert the best performance of the engine. The transmission can produce different gear ratios between the engine and the wheels while the car is running.
By shifting gears, the engine can work in its best power performance state. The development trend of transmission is becoming more and more complicated, and the degree of automation is getting higher and higher. Automatic transmission will be the mainstream in the future.
