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 are obtained under varying conditions of load and speed.

FIFA WORLD CUP HISTORY

Image
Federation International The Football Association The success of the Olympic Football Tournament intensified FlFA's wish for its own world championship. Questionnaires were sent to the affiliated associations, asking whether they agreed to the organization of a tournament and under what conditions. A special committee examined the question, with President Jules Rimet the driving force. He was aided by the untiring Secretary of the French Football Federation, Henri Delaunay. Following a remarkable proposal by the Executive Committee, the FIFA Congress in Amsterdam on 28 May 1928 decided to stage a world championship organized by FIFA. Now, the organizing country had to be chosen. Hungary, Italy, the Netherlands, Spain and Sweden submitted their candidatures. Right from the start, Uruguay was the favorite and not simply for its Olympic gold medal wins in 1924 and 1928 - the country was celebrating its 100th anniversary of independence in 1930 at great expense. Moreover, it...

CRANKCASE

http://en.wikipedia.org CRANKCASE         The main body of the engine to which the cylinder are attached and which contains the crankshaft and crankshaft bearings is called crankcase.This members also holds other parts in alignment and resists the explosion and intertia forces.It also protects the parts from dirt etc. In the crankcase only the engine oil are stored in self lubricate syst em the crankcase play an important role the scoop used for splashing to the engive wall are taking oil from the crankcase only so I play a majore role in lubrication system      Crankcase forming an engine block ,crankcase  are the basic engine structural component   crankcase often has an opening in the bottom to which an oil pan is attached a gasketed bolted joint. Material used for crankcase  Material which is used for making crankcase are engine block mostly cast aluminium crankcase are made via sand casting ...
