Clutch design of Changcheng saifo F1car
Abstract: Clutch is an important component in the automotive transmission. Main function is to cut off the engine and the realization of the power from the transmission to ensure a smooth start and prevent transmission from overload.Diaphragm spring clutch in car in recent years,widely used as a vehicle clutch.Its large capacity ,stable torque and easy operation, good balance, but also mass production for which research has become increasingly important. This design specification describes in detail the diaphragm spring clutch light vehicle structure, parameter selection and calculation
Based on the selected engine capacity and vehicle-related parameters, design, determined to push-type diaphragm spring clutch as a design goal。Push-type diaphragm spring clutch according to the principle and application requirements, the use of systematic design method is divided into active part of the clutch, the driven part of the control mechanism. Through the design of various parts of the principle of interpretation and the advantages and disadvantages compared to determine the relevant part of the basic structure and components of the manufacturing materials. According to traffic conditions and vehicle parameters, in accordance with the clutch system design steps and requirements, mainly for the following work: select the relevant design parameters, clutch size parameters, the determination of clutch back coefficient β, the determination of unit pressure P, the determination of friction plate diameter D. And were designed primarily for assembly: shock driven plate design, the design pressure plate, clutch cover design and the design of the diaphragm spring.
Key words: clutch diaphragm springs friction plate driven plate pressure plate.
