Abstract
Conventional transmission system uses single plate clutch with a manual transmission gear box. Many methods of automatic clutch control namely electro-magnetic clutch, pneumatic clutch control etc. have been tried but due inherent disadvantages and maintenance problems they have been replaced back by conventional method. The auto-disengagement single clutch employs only one set of compression springs instead of the usual two sets, with this arrangement it is possible to reduce the weights of the centrifugal member .When the clutch is disengaged and the engine is running at idling speed the hinged bob-weights rest against the lower or inward sides of holes in the flywheel. When the engine is accelerated above 700 to 800 rpm , the weights fly outwards and in doing so their lever ends compress the springs so as to engage the clutch plates. When the full engagement pressure between the clutch members has been attained any further increase in engine speed brings the bob weights against the outsides of the flywheel holes, thus limiting the pressure plate action. This arrangement keep the clutch in normally disengaged condition unlike the conventional clutch that is in engaged condition and has to be disengaged by manual Lever. The modified system utilizes the centrifugal force developed by engine acceleration , where as the temporary dis-engagement of clutch required at the time of gear change is a solenoid actuated by switch in gear change knob. The hold time of the solenoid is only a few seconds thus prolongs solenoid life and reduces power consumption from battery. The conventional clutches use full ace lining for the clutch meaning that the entire face of clutch is lined with friction material and conventionally the friction lining material used is asbestos base. ANSYS is used for the calculation of stresses, demo model built up for testing performance of clutch at various speed. This clutch may reduce jerk, transmission losses and increase performance of automatic clutch.
