Centrifugal clutch

                      Centrifugal clutch Intro Centrifugal clutch is mainly used in automatic gear system .compare to other clutch types its costly   but it has more advantages then other system. Working The centrifugal clutch automatically disengages itself when the speed falls below and engages when the speed rises above a pre-set value. centrifugal bob-weight are positioned in such a way that the centrifugal forces exerted by them with the clutch rotation result in the release levers due to the outer end of the release lever moving towards the flywheel . This results in the proportionate increase of centrifugally generated pressure with the increase of engine speed. Therefore at low engine speeds only the spring pressure acts, while at high engine speeds the force generated by the weights supplements the spring pressure. Thus smooth and acceptable gear changes...

Flywheel

Flywheel The flywheel is a disk or wheel attached to the crank, forming an inertial mass that stores rotational energy. In engines with only a single cylinder the flywheel is essential to carry energy over the power stroke into a subsequent compression stroke.   Flywheel mostly present in reciprocating engines to smooth out the power delivery over each rotation of the crank and in most automotive engines also mounts a gear ring for a starter. The rotational inertia of the flywheel also allows a much slower minimum unloaded speed and also improves the smoothness at idle .the flywheel may also perform a part of the balancing of the system and so by itself be out of balance although most engines will use a neutral balance for the fly wheel ,enabling it to be balance in a separate operation. The flywheel is also used as a mounting for the clutch or a torque converter in most automotive applications. Material Flywheel   are typically made by steel and also carbon fiber is u...
