Clutch, How does it work ?


Have you, ever wondered what is happening inside a car, when you press the clutch pedal Or, why, do you need, to press the clutch pedal before you shift gears in a manual transmission car This, video gives you, logical answers to these questions At the end of the video we will, also understand the crucial role played, by the clutch in an uphill start To, understand the need for a Clutch let’s first understand the anatomy of an internal combustion engine car Internal combustion engines have a very limited torque band and Due to this reason in order to efficiently vary the speed of the drive wheels internal combustion engine cars need a transmission system The use of this transmission makes sure that the engine is working within its optimum rpm range and by changing gear According to the driving conditions the transmission helps to control the drive wheel speeds In a manual transmission car making these gear changes is not an easy task to have a smooth gear change with a Manual transmission the engine power flow to the transmission has to be discontinued However it is not practical to turn off the engine just for this gear change The clutch is used for this purpose in short the clutch is a mechanism to disconnect the flow of power to the transmission without turning the engine off Let’s understand how it works The main part of the clutch consists of a disc coated with high friction material on both sides a simplified clutch disc is shown here this disc sits on the flywheel if An external force presses against the clutch disc the clutch disc also will turn with the flywheel due to the frictional force The input shaft of the transmission is connected to the disc So that when an external force is applied to the disc the engine power will get transmitted to the transmission system This external force is provided by a Pressure plate spring system Cover of this system is attached firmly to the flywheel So the pressure plate will firmly press onto the friction clutch disc and the engine power will be transmitted to the transmission system But this is the case in normal driving so how is the power disengagement done with the clutch For the disengagement purpose a special kind of spring is introduced in the pressure plate Assembly, this spring is known as a diaphragm spring To understand this diaphragm spring better, assume that the diaphragm spring motion is fixed around This circle in this case if you press the center portion of the spring as shown the outer portion should move in the opposite direction The diaphragm spring sits between the pressure plate and the cover To understand this configuration better let’s take a cross-section of the assembly the outer portion of the diaphragm spring is connected to the pressure disc This means if you press the inner portion as shown the pressure disc will move away from the friction disk thus the power flow will discontinue to the transmission This is exactly what happens when you press the clutch pedal A hydraulic system transfers the clutch motion to the center of the diaphragm spring When the diaphragm spring is pressed the power flow is discontinued? During this time you can make a gear change the clutch pedal is released after the gear change and the power flow continues again This is how a clutch works In an actual clutch you can see a few coil springs on the clutch disc what’s the purpose of these springs These are used to smooth out the fluctuations and vibrations from the engine power output It is clear that the hub and disc are not directly connected The engine power first reaches the disk then it transfers to the springs and finally to the output hub This means that the springs will dampen out most of the power flow Fluctuations from the engine and the motion transferred to the vehicle will be much smoother Now, let’s explore an extremely important and difficult task in driving cars with manual transmission starting from uphill Even in a car without a handbrake you can use this clutch technique to start, while pointing uphill In an uphill start initially both the brake and clutch pedal are pressed, while the engine is running Now, release the clutch pedal partially until you feel the clutch bite The clutch bite can be experienced at. Your foot it may feel like the engine is shivering at This point even if you release the brake pedal you can see the vehicle will not roll the Partially released clutch acts like a brake now You can press the gas pedal and the car will move forward The big question here is how does the partially release clutch act like a break This break phenomenon is nothing but a game of force balanced in a perfectly forced balanced condition the vehicle Wheels will not be able to roll and the gravitational pull will be the same as static frictional force at the wheels The vehicle wheels are prevented from rolling by another force balance Force balance between the engine forward force and the same static frictional force When you partially release the clutch and it balances for the clutch bite you are unknowingly doing all these force balances When these forces are in perfect balance the wheels the transmission system and the clutch disk will not be able to spin This is how the clutch bite acts as a brake but remember the frictional force between the rubbing surfaces Produces the engine forward force in this case this will result in wear and tear of the friction material on the clutch disc We hope this video will enable you to be a better engineer and a better driver Please support our educational activities at and don’t forget to subscribe thank you

    End record and report from their database.

    These ones are grade F all.

    All customers hate these ones forever and drive below 1 mpg, over 100 l/100km, below 1 km/l.

    Code forbidden AE styles for don't build all in the last page.

    Code forbidden AE styles had started all prisoners death level, all bountry hunters, all street racers, all spies, all humoid bountry hunters, all terrorists hire engineers build for destroy all AE economics.

    End report by themselves and record about their cargos.

    * Law dearth mean their status prisoners level death.
    * These ones effect EV, hybrid series all.
    No ones stop them about these ones on automotive engineering and automobiles market.

  48. Pedro Simoes says:

    I don't know if I can explain my doubt but I will try. If the transmission is connected to the whells and the wheels are spinning wouldn't I need a second clutch to stop the wheels turning the transmission?

    Clutches were mysterious prior to this video. Still mysterious after

  63. nonoyo beezewax says:

    I'm kinda surprised that manual transmissions are still being installed…even in sports cars. Don't get me wrong I own manual transmission sports car and like it, but that type of configuration is a true dinosaur.

  73. Mark Mccastle says:

    Engine rotation is reversed

  74. R R says:

    Well to start uphill is SIMPLE , use your handbrake… When starting uphill,makesure your handbrake is pulled. Then, press gas padel and clutch in the same time. The rpm should be higher. Then, release the clutch slowly. When the rpm is slowly going lower, put the handbrake down. Walla! Your vehicle should be moving… In the hard way…

  82. Simon John Hinton says:

    I know how to get the most out of a old Peugeot 405's clutch was worn down to the rivets and the release bearing was just a lump of molten metal but I still managed to get home. £450 for a new clutch kit+labour

  83. It aint Ralph tho. says:

    I learned how to drive stick in a cdl tractor, im sure if i got in a manual car id break it.

  84. Venky Babu says:

    Knots created and knots loosened to control movements. Just like HP.

  85. SUB-ZERO says:

    I only use the clutch when I'm stopped and want to go after that I don't touch it you either power shift or tell your story walking if you read your owner's manual it tells you exactly when and what RPM and what speed to ship that they're for eliminating the need for a clutch you pansy

  86. Kinang Eagle says:

    How come Chris Fix’s video looks so much different

  87. Riman Chowdhury says:

    I can barely do my math homework

  88. Doktor Kranium says:

    how are these even remotely reliable and resistent to wear … i have no clue
    it's reliant on friction and some metal springs … how do these even last more than 30 minutes??
    give me a metal spring and i can play with it for 30 minutes and it'd be shit

  89. Ben Walker says:

    I've been driving a manual for over ten years and never knew how about the uphill start technique.

  90. Saurabh Yadav says:

    I have seen these videos so much still I fail to understand which wheel runs what when the gear is changed and how does the gears don't grind…I am actually dumb

    Muy chingon

  92. Shantanu Inamdar says:

    Wouldn't the clutch bite method damage the clutch plate over long time
