What is a Clutch?• Couples two rotating shafts or other rotating components with

different speeds

Most Commonly known use• Automobiles (motorcycles)• Used when shifting gears or when stopped

ComponentsA clutch disc has two lining sections that are riveted to the marcel.

How it works

• Clutch Animation• Video Description

How it works• Most older vehicles use mechanical clutch linkage.

How it works• The hydraulic clutch linkage reservoir, master cylinder, and

slave cylinder are connected by metal and plastic lines. Note the release bearing and concentric slave cylinder.

Typical Failure• Wear on friction plates or clutch disk/plate• Consequence: could slip

Other Typical Failure• Mishandling

• Could cause slight clutch deformation (1 mm gap required for successful operation)

Other Typical Failure• Overheating

• When clutch is used too frequently it leads to over heating of friction plate

• “Riding the Clutch”• Results:• Reduced friction coefficient• More time to reengage• Leads to wear
