Types of clutches

Types of clutches
In my previous post I discussed about the clutch mechanism and what is clutch so here I don’t want to waste your time, so here I’m going to tell about types of clutches briefly clutches are basically classified according to their construction and performance different types of clutches are
1.       Multiple plate clutch
2.       Single plate clutch
3.       Wet vs. dry
4.       Centrifugal
5.       Cone clutch
These are the major types of clutches

1.   multiple plate clutch
Multiplate  are mainly used in large trucks and racing cars if torque transmission is necessary but the diameter is limited these are also used in automatic transmission and motor cycles in this type of clutches a number  of parallel discs of metal and friction material are arranged to transmit the drive in this type of clutches a number of parallel discs of metal and friction material are arranged to transmit the drive in comparison to the single plate type these are smoother and easier to operate the increased number of plates friction discs provide the increased torque carrying ability thus making it suitable for use in heavy commercial vehicles and special purpose the military and agricultural vehicles. These clutches may be dry or wet. 
Wet clutch
Wet clutches consists of thin plates made of steel fitted to the engine shaft and those on the gear shaft are made of phosphor bronze. These plates are immersed in a bath of oil and also have grooved surfaces for permitting the oil to flow through them. These grooves help to dissipate the heat generally used in conjunction with or as a part of the automatic transmission.
Dry clutch
The multiple dry clutches has different plates lined with a frictional material similar to that used in case of a single plate clutch.
    Cork inserted multiple clutches are used in motor cycles while those with metal plates are used in tractors or other light powered engine vehicles. To avoid scorching or changing of cork-inserts due to frictional heat, it is necessary to have the clutch oil-cooled.

What are the most fascinating science facts?

The blood would appear  green  in color in deep sea/ocean. Water can  boil  and  freeze  at the same time. If you took out all the  empty space  in our atoms, the human race could fit in the  volume of a sugar cube . Lasers can get  trapped  in a waterfall. A  teaspoonful  of neutron star would weigh  6 billion tons . The Eiffel Tower can be  15 cm  taller during the summer. Babies have around  100 more bones  than adults. An egg looks like a  crazy jellyfish  underwater. A flea can  accelerate faster  than the Space Shuttle. A single solar flare can release the equivalent energy of  millions of 100 megaton atomic bombs . Cats always land on their  feet . If you  spin  a ball as you  drop  it ,  it  flies .

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 ...
