Input. The clutch in mechanical transmission is as a stand-alone assembly and exist, it is the transmission system of connected directly with the engine of the assembly.At present, various kinds of car widely adopted by the friction clutch relies mainly on the stationary part of the friction subordinate to transfer power and can separate device. Clutch seemingly simple structure, working principle, but the structure of the shallow development has experienced hundreds of years, the fusion of generations of wisdom and efforts to reach the point of today.In the modern automobile, diaphragm spring clutch used more widely, combined with BYD cars and manufacturing technology of the main parameters design rumsfeld diaphragm spring clutch. BYD cars than technical parameters for the main design basis, and refer to the domestic and overseas relevant clutch design convenient books and material, in the design of the main design of friction, the diaphragm spring, platen assembly, pressure plate, etc.In the design and analysis of diaphragm spring than ever to push type diaphragm spring of advantage, and the friction of films and diaphragm spring optimization design.
