Derived through a detailed process of the accumulation of a large amount of data and to map out the success of the diaphragm spring clutch of the finished map. Describes the development of the clutch, and its working principle, in the process, after parison with the right to determine the initial structure of the clutch, select the pulltype diaphragm spring clutch, and a reverse shock absorber for the back calculation provides a theoretical basis. In the calculation, first determine the size diameter friction plate, and then according to the size of other parts assembly and design is calculated. Check by calculating the friction plate diameter size, calculated to select the size of other ponents, and then check them to see whether it can meet the design requirements. Design including the design of the driven disc assembly verification, the design of the pressure plate check on the clutch cover, clutch cover design verification and design verification and optimization. Calculation of the specific design of the friction plate, reversing the shock absorber, diaphragm spring, pressure plate, clutch cover, transmission ponents, such as chip assembly After pletion of the above work, through puter Pro / E software to study the use of the general assembly of the clutch driven plate assembly, pressure plate, diaphragm springs, friction plate for a draw, in the process of drawing on the clutch assembly have a better understanding of, and improved the calculation of the missing part. The design of the original design of the clutch to optimize and modify the proposal, its future role in the design process from the reference. Achieved through optimization of the design to improve the original clutch and improve the use of this type of vehicle, fort, and enhance the work of automobile efficiency.
