The coupling installs between the engine and the transmission gearbox, the automobile from the start to the travel entire process, needs to use the coupling frequently. Its function is causes between the engine and the transmission gearbox can join gradually, thus guaranteed that the automobile starts steadily; Shuts off between the engine and transmission gearbox's relation temporarily, is advantageous shifts gears and reduces shifts gears the time impact; When automobile emergency brake can play the separation role, prevents transmission systems and so on transmission gearbox to overload, plays certain protective function. The coupling similar switch, the joint or breaks to the power transmission function, therefore, any form's automobile has the engaging and disengaging gear, is only the form is different. Now, the electronic technology also entered the coupling system. One kind the coupling which (ECU) controlled by the control unit already applied on many patterns sedan race car.
My designs are based on the data to design a lucky EC718 with matching clutch, clutch structure which includes the selection of the program, determine the main parameters, design of diaphragm spring, pressure plate design, reverse the shock absorber designdriven plate design.
Key words: Driven disc unit , Power transmission , Disk spring , Misalignment elastic property。
