Diaphragm clutch

DIAPHRAM CLUTCH

                                 Diaphragm clutch 

 Construction Details Of Diaphragm  Clutch:

•Similar to single plate clutch

•Diaphragm spring is used instead of coil spring

•Diaphragm spring is a large disc of conical form

•It contains number of radial fingers in its centre portion 

•It takes on a flat shape in engaged position 

•Diaphragm spring also known as Belleville spring

•Flywheel fixed on engine shaft (crank shaft)

•Clutch plate is freely mounted on the splines of the clutch shaft

•Pressure plate assembly fixed to the flywheel  

 

 Working of diaphragm clutch:

 

 Clutch engage 

 •Diaphragm spring takes on flat position and exerts a load upon the pressure plate 

 •Pressure plate exerts pressure on clutch plate, to keep in contact with  flywheel

 •Clutch plate rotates with fly wheel 

 •Clutch shaft also rotates and power is transmitted

 

 Clutch disengag: 

 •When driver presses the clutch pedal 

 •Diaphragm spring takes on its original shape of conical form

 •There is no pressure exertion by pressure  plate on clutch plate

 •Clutch plate moves axially outwards and stops rotating

 •Power is not transmitted from engine shaft to clutch shaft

 Advantages of diaphragm clutch:

 

 •It is a more Compact means of storing energy. This results in smaller clutch housing 

 •Even in worn out condition the spring force is not less than the required 

 •Diaphragm spring acts as both clamping spring and release levers

 •Low operating effort 

 •Better balancing 

 •Accurate operation at higher engine speeds 

 •It is less effected by the centrifugal forces 

 

 Disadvantages of diaphragm clutch:

 

 •In sufficient clamping force in case of larger diaphragm
