ABSTRACT 
Clutch is an important part of vehicle drivetrain, main function is to cut off engine power to the transmission system, ensure the car a smooth start to ensure works smooth shifting of the transmission system, and limits the maximum torque on the transmission system, prevent drive system overloads. This design gave a detailed description of the process parameters selection and calculation of diaphragm spring clutch.
This article according to the Chang'an JieXun performance parameters of the car, identified as a design goal to push the diaphragm spring clutch. According to push the diaphragm spring clutch work principle and application requirements, determines the basic structure of the parts and components manufacturing materials. Ascertained in accordance with systematic design method of the clutch friction plate diameter d, reserve coefficient β, pressure p, f, the number of friction surface friction coefficient z and clutch gap Δt, design the diaphragm spring, clutch driven plate Assembly, clutch cover Assembly and separation control, checking the temperature rise of the pressure plate, checking the friction of sliding friction.
