Clutch principles
|
The clutch used in most light vehicle applications is a single plate friction type. The clutch transmits torque from the engine to the transmission and a release mechanism allows the driver to control the flow of torque between them.
|
Single-plate clutches
|
A single-plate clutch unit consists of a friction type disc, a pressure plate assembly, and a release bearing and operating fork.
|
Multi-plate clutches
|
Increasing the number of plates in a friction clutch unit, increases its torque capacity.
|
Dual mass flywheels
|
The function of the Dual Mass Flywheels or DMF is to isolate torsion crankshaft spikes created by diesel engines with high compression ratios.
|
| Operating mechanisms |
The clutch operating mechanism may be mechanical or hydraulic. When the clutch pedal is depressed, the movement is relayed to a release fork which carries the release bearing. |
