Title The Design of Diaphragm Spring Clutch for Medium-duty Truck
Abstract
The clutch is one of the important parts of the automobile transmission system, it plays a significant role to transfer power,to prevent vibration and overload system.Automobile clutch is generally assembled with screws on the flywheel shell between the engine and gearbox ,and the input shaft of the gearbox is the output shaft of the clutch.In the car,the clutch pedal can be released or down,so that the gradual bonding,and the temporarily separating of the engine and gearbox to transfer or cut off the engine to the transmission input power.At present,friction clutch is widely used in all kinds of cars which can separate easily and depends on the friction between driving part and driven part to transfers power.
This design is basically to design diaphragm type spring clutch of the medium truckloads.According to the procedures and requirements of the clutch design,the basic parameters is the first choice,second to parts design:driving part,driven part,pressing agency and control agency.At last,analysing the relevant respectively according to various spare parts working conditions,so as to ensure the best comprehensive performance of the clutch designed.
