AUTOMOTIVE CLUTCHE SYSTEM

AUTOMOTIVE CLUTCHE SYSTEM

• 1.
  AUTOMOTIVE CLUTCHE SYSTEM •an automotive clutch is used to conect and dis connect the engine and manual transmission or transaxle. • the clutch located between the back of the engine and the front of the transmission.

  CLUTCH DISC • TheClutch Disc Is Connected To The Input Shaft Of The Transmission, And Is Located Between The Flywheel And Clutch Cover Assembly. The Flywheel Is Connected To The Engine Crankshaft And The Clutch Cover Assembly Is Attached To The Flywheel. The Clutch Release Fork Forces The Clutch Release Bearing Against The Diaphragm Spring Of The Clutch Cover Assembly. • Clutch Disc The Clutch Disc Connects The Engine And The Transmission Providing For Smooth Engagement. • Circular Groove To Eliminate The Problem Of The Clutch Disc Adhering To The Flywheel And Pressure Plate, Grooves Are Provided In The Clutch Disc Facing.

  Flywheel • The FlywheelIs Connected To The Engines Crankshaft. A Flywheel Is Very Similar To A Brake Rotor In Appearance. It Is A Large Metal Disc That Stores And Releases Energy Pulses From The Crankshaft. It Drives The Clutch By Providing A Friction Surface For The Clutch Disc. In Addition, The Flywheel Provides A Mounting Surface For The Clutch Cover, And Also Dissipates Heat. • A Flywheel Is Very Similar To A Brake Rotor In Appearance. It Is A Large Metal Disc That Stores And Releases Energy Pulses From The Crankshaft.

  Master Cylinder When ForceIs Applied To The Pushrod, The Piston Displaces Hydraulic Fluid In Chamber A Of The Master Cylinder (As Shown In Figure ). During Initial Piston Travel, The Compensating Port In The Master Cylinder Is Closed By The Piston. Further Piston Travel Allows Fluid To Be Displaced, Transmitting Force Through The Clutch Line To The Release Cylinder Located At The Transmission. When The Pushrod Is Released, The Piston Is Returned To Its Initial Position By A Spring. With The Compensating Port Open, Pressure In Chamber A Equalizes With The Reservoir. If The Compensating Port Is Blocked, Any Expansion Of The Fluid Due To Heat Could Cause Pressure In Chamber A To Increase. During Normal Clutch Wear, This Condition May Eventually Cause The Clutch To Slip.

  Common Clutch Problems 1.materialon the disc wears out due to constant friction. 2.Broken Cable: The cable needs tension to push and pull. 3.Leaks: Leaks within the cylinders keep them from building up the right amount of pressure to function normally. 4.Misalignment: When you press the pedal the linkage transmits the wrong amount of force. 5.Air in the Hydraulic Line: Air gets into the line where fluid needs to be in order to build pressure. 6.Hard Clutch: If you need more force than normal to press your clutch this can indicate a problem.
