Generally, a car needs to replace its clutch every 10 kilometers or so. The clutch is located between the engine and transmission and is the "switch" for power transmission between the engine and transmission. It is a transmission mechanism that can both transmit power and cut off power. Its main function is to ensure that the car starts smoothly, reduce the impact load of the transmission gear, and prevent the transmission system from being overloaded when shifting gears. When a car needs to shift gears, it is usually achieved by disengaging and engaging the clutch. Power transmission is temporarily interrupted between disengagement and engagement to ensure smooth shifting. In a race against time, the operation of the clutch is very critical. Abnormal operation will cause the speed to slow down and affect the performance of the car. Most dual-clutch plates need to be replaced every 10 kilometers, but the actual frequency of replacement needs to be determined based on personal driving habits. The concept of dual-clutch transmission has a history of sixty or seventy years. As early as 1939, Germany applied for a patent for a dual-clutch gearbox for the first time; it proposed a design concept for a manual transmission, which consisted of two parts. One part transmits the odd-numbered gears, and the other part transmits the even-numbered gears, and its power transmission connects the two input shafts through two clutches. The driven gears of adjacent gears are staggered with the two input shaft gears. Through the adjustment of the two clutches, the transmission ratio can be changed without cutting off the power. This will reduce the shift time and improve the shift quality.
