to increase the strength of the material and decrease the weight of the material
Cast iron is the material often used to design screw jacks because of its strength.
induction motors have very little starting torque as the motor come up to speed it reduces the torque load until it gets near synchronous speed
plastic
Fiber glass
Yes, but looking really does not mean it is bad but- if you see hardly any clutch material its bad, if there is a burned plate, its bad. Some times it is not the clutch plate but the pressure plate springs or the throwout bearing.
A clutch pressure plate is used to clamp the disc to the flywheel and transfers the power to the transmission.
"What is the difference between single plate clutch and multi plate clutch?"
the material is buffing coumpound
Cars use a single plate clutch as there is enough space to use the correct dia plate to create the right amount of torque, while motorbikes use multi-plate clutches because they have limited room and need to create more friction surfaces to produce the required torque.
At the clutch plate and the pressure plate.
A clutch is that part of engine which engages or disengages power from the engine crankshaft to transmission. A clutch is mechanism by which you change the gears. In simple words, it turns on or off power to rear wheel. A clutch is made of clutch assembly which includes clutch plate, Clutch basket, Clutch hub, pressure plates, Clutch springs, lever and clutch cable.Clutch Basket: It is bowl shaped basket which holds entire clutch assembly. It has teethes on the outside surfaces which fix on the primary drive teethes. It means that it is connected with the transmission. It is bolted onto the end of clutch shaft.Clutch Hub: The clutch hub places between clutch basket and pressure plate. The clutch plates are mounted on it. It has teethes in the centre hole which rotate with main shaft. It means it is connected with the engine.Clutch Plate: There are two types of plates in clutch plate. One is Drive (friction) plate another is Driven (Steel) plateDrive (friction) plate: The friction plate is ring shaped and coated with fiber. It is a wear and tear part of clutch assembly. The friction plate surfaces interface between the clutch basket tangs (gaps) and pressure plate. It has teethes on the outside surfaces. These teethes fix on the cutouts between clutch hub tangs (gaps). It is coated with the same material as you see in brake pad (shoe).Driven (steel) plate: It is ring shaped and made of steel and sometime of aluminum. The surfaces of steel or aluminum plate interfaces between pressure plate and clutch hub. It has teethes on inside surfaces. This teethes are fix on the cutouts of clutch hub. Mostly steel plates are used in clutch assembly due to their durability. The aluminum plates are used in Moto GP due to their lighter weight. These plates are worn out very fast compare to steel plate.Pressure Plate: It is the moving part of the clutch assembly which works against clutch spring tension. It releases the clamping action on the clutch plates when the clutch lever is engaged.Clutch springs: The clutch springs shape is like short coil. These springs continuously hold the friction and steel or aluminum plates through spring tension. It also prevents slippage except when the clutch lever is engaged. Most of motorcycle has five or more springs used per clutch assembly. For higher engine output stiffer or more springs are used while softer or few springs used in order to lighter clutch level pulling effort.Lever: It is metal rode which pivots on a perch located of the left handlebar. It gives input to clutch assembly.Clutch Cable: The clutch cable is a cable through which the rider's input passes to the clutch internals.Clutch Cover: It covers the entire clutch assembly
Clutch, yes. Pressure plate, No.
High grade spring steel. (Hardness with some flexability, not "springs" like a conventional "pressure plate".)
Broken clutch cable or clutch pressure plate fork.
The springs around the clutch plate have probably came out and locked up between the pressure plate and the clutch plate and locked them together. you need to change the clutch plate and have the pressure plate checked for damage.
a pressure plate works by springs. when disengaged the tension is released from the springs which hold the clutch plate against the flywheel,allowing the clutch plate to spin free,which basically stops the transfer of power from engine to gearbox when clutch is engaged the tension is reapplied to springs in pressure plate forcing the clutch plate against the flywheel
