  1. ClutchesWorking and Application

  2. TABLE OF CONTENT • Introduction to Clutches • Components in a Clutch • Types of Clutch • Working of a Clutch • Equations Involved in a Clutch • Material used to make Clutch

  3. INTRODUCTION TO CLUTCHES 

  4. PURPOSE OF A CLUTCH The Clutch serves the two purpose: • Allows engine to be disengagedfrom transmission for shifting gears and coming to a stop • Allows smooth engagement of engine to transmission

  5. WHO REQUIRES A CLUTCH The Clutch serves the two purpose: • Allows engine to be disengagedfrom transmission for shifting gears and coming to a stop • Allows smooth engagement of engine to transmission A picture of an old racing car with primitive clutch system

  6. LOCATION OF A CLUTCH Depending on the type of drive, the clutch changes its location: • Rear wheel drive • Front engine • Rear engine • Mid engine • Front wheel drive

  16. TYPES OF CLUTCHES 

  17. DIFFERENT TYPES OF CLUTCH In this presentation, basically three types of clutch has been explained: • Dog Clutch • Belt Clutch • Centrifugal Clutch

  18. DOG CLUTCH • A dog clutch is a type of clutch that couples two rotating shafts or other rotating components not by friction but by interference. • The two parts of the clutch are designed such that one will push the other, causing both to rotate at the same speed and will never slip. • Utilized in automobile manual transmissions.

  19. BELT CLUTCH • Engine power is transmitted via a set of belts that are slack when the engine is idling, but an idler pulley can tighten the belts to increase friction between the belts and the pulleys. • Used on agricultural equipment, lawn mowers, tillers, and snow blowers.

  20. CENTRIFUGAL CLUTCH • This clutch system employs centrifugal force to automatically engage the clutch when the engine rpm rises above a threshold and to automatically disengage the clutch when the engine rpm falls low enough. • A centrifugal clutch is used in some vehicles (e.g., mopeds) and also in other applications where the speed of the engine defines the state of the clutch, for example, in a chainsaw.

  21. WORKING OF A CLUTCH 

  22. STEP-WISE WORKING OF A CLUTCH 1 | When the clutch pedal is depressed, the "Throw-out bearing" pushes the pressure plate's release fingers. 2 | The pressure plate pulls away from the clutch disc, disengaging the clutch, thus interrupting power flow When the clutch pedal is released and the clutch is fully engaged, the release bearing is normally stationary and does not rotate with the pressure plate. 3 |

  23. STEP-WISE WORKING OF A CLUTCH -2 4 | Clutch operation is accomplished either mechanically or with a hydraulic pressure system. If a vehicle has a mechanically operated linkage, it will incorporate either a shaft-and-lever linkage arrangement or a cable. 5 | Systems that are made up of linkages, levers and pivot points are found primarily on older vehicles. 6 |
