Early car clutches actually came from other mechanical devices. According to information, the first-generation clutch is a flat belt. However, the transmission efficiency of the belt is too low and the wear and tear are very serious. Especially on rainy days, the power transmission is more prone to problems. As the transmission gear increases, the clutch must continue to bear more torque, so people have invented a variety of clutches, including the pioneer of the modern clutch - the clutch based on the principle of friction.
The diaphragm spring clutch was born in 1936 in General Motors' research lab and was mass produced in the United States in the late 1930s. In the mid-1950s, it was applied to a few single European models. Mass production of the diaphragm spring clutch began in 1965 with the Opel Rekrod model. In the past few years, the variety of diaphragm spring clutches has fully covered the domestic demand for heavy, medium, light, sedan, micro, and agricultural models. In the early years, in order to transmit more torque, heavy truck clutches used two friction plates, that is, double-disc clutches.
However, the two friction plates are easy to cause the problem of incomplete separation. Therefore, in recent years, with the improvement of material technology, heavy trucks have gradually been changed to single-plate clutches.
