How a clutch works - internals of transmission and clutch assembly

[thefunnyguy1110]

so how do people "burn out" their clutch?

[paulhunter123]

i dont get how the pressure plate when pushed in pulls the disc backward?

[garysmart1]

@paulhunter123 I BELIEVE THE PRESSURE PLATE ITSELF DOES IT...

[smirnofowner]

@paulhunter123 it doesent, the "disc" clutch friction disc rides on splines and slides slight bacwards when the clutch i engaded. In some cases rust and debri makes the dics stuck and it can be noted by more force to get into first and reverse, even a slight burr in reverse can be heard, in some cases you must turn the engine off to engage reverse.

[GeneralG1810]

@paulhunter123 Its got a series of "fingers" that act as levers to pull it back the bearing runs on them so they dont wear out. Just google image pressure plate and you'll see

[wirayut123]

cool

[tunisiangeek]

EXCELLENT VIDEO !! Now I understand the whole thing

[djlaiguana1]

Hi Buddy, I have a 93 ford Truck E-350 1 Ton Econoline - Van and something happened with the transmission (automatic), full fluid level its OK but when into 1 and 2 .... the truck runs good but for 3rd and 4th the RPMs go up and up (foot on gas accelerating), but the truck doesn't speed up .... i'm stuck on 1st and 2nd...

-Solenoid problem ?

-Should I reset by disconnecting battery ?

-No OD light flashes in dashboard.

-No ''CHECK ENGINE'' light.

Thanks for any help ...

i want it too:)

[ItzCashew]

this reminds me to change my squeaking clutch slave

[SuperPenetration]

Im going to auto school for couple of months, and i wanna know how every little piece works so my instructor sends me to WTCC straight from the polygon :D

[shnrbtlle18]

Whats a question??



[jeremybrown1942]

what is a clutch?

[THEIRONMAN9]

whats a car ?



[gilk1991]

@crazunwo yeah thats something inside it can be thr master cylinder either one or ur flywheel its too old u have to rplace it.

[RamboCambo253]

push type clutch?

[richu27]

3 people drive automatic.

[herbienbrian2]

wow, cool. I get it now!

I've taken clutches apart, replaced them, and drive nothing but them!

But this is the first time I really understand how they work.

[harrykhehra]

beautiful



[villani27]

Nice! Now why does a clutch wear out? do the springs wear or the teeth dull or what?

[TheGreatestUFFan]

@villani27 A clutch is like a spherical brake pad. When it stops working or burns out it ceases to grab.

[teju9111]

nice 1



[jaileea2008]

neat!!!!!!!!!!!!!!!!!!!

[blindskater200]

I'm not very familiar with Japanese vehicles but I do know that a Chevy slave cylinder is just a round bearing type thing with two hoses going to it to press and depress the pressure plate. This looks more like a mechanical (instead of hydraulic) mechanism. This set up reminds me of older vehicles like my '88 Mustang. With the throw-out bearing on the clutch fork. Can any one enlighten me? Is this actually a slave cylinder in the vid or not?

[R20173]

this is awsome!!!...very very helpfull

[jorge199516]

thank you very much helped me through a lot since I subscribed to your channel

[bamboali]

thx finally understand it :)

[BuKuTyyy]

damn nature u scary

[SuperStoner90]

one person burned their clutch becouse they cant drive.... :(

[newage4energy]

Jozu neh! O Negai shimas. Dekiru?

[brujonagual]

i thought it work by magic

[patrix404]

JAP POWER!

[montey1017]

go stickshift or go home!

[UunonMopo]

@montey1017 go fuck yourself

[montey1017]

@UunonMopo well, someone got ran over by the PMS express...

[UunonMopo]

@montey1017 what express is that?

[montey1017]

@UunonMopo just shows butthurt...I don't know why you were so offended by my preference of stickshifts.

explenation to the joke in my previous comment, which clearly flew waayy over your head:

I was comparing PMS to getting hit by a train, pretty much I said you got hit by that time of the month really, really bad.

[UunonMopo]

@montey1017 very funny fonzie

[montey1017]

@UunonMopo so many tears...

[UunonMopo]

@montey1017 civic is better than supra

[montey1017]

@UunonMopo how is that relevant to anything?

[UunonMopo]

@UunonMopo civic stick is better than supra stick

[montey1017]

@UunonMopo your comparing a stickshift to a stickshift, and you got pissed at me about comparing a stick to an auto...

[Lolwut67]

@montey1017

I have a hand clutch cause I ride a manual quad. That count?

[jaydnls15]

I think its a lil slower. If you watch the crank journal at the first five seconds it only does half a turn

[xstr33tr4cerx]

@jaydnls15 yah trans is not supposed to spin at the same speed as the engine man cmon how are you supposed to accelerate if the engine and trans spin at the same rate

[jaydnls15]

@xstr33tr4cerx Nobody said the trans. I said the clutch and if ya wanna be technical about it the pressureplate and flywheel ALWAYS spin the same speed as the motor and the clutch disk ALWAYS spins at the same speed as the input shaft. and when the clutch is engaged the input shaft on the transmission and the motor ALWAYS spin at the same speed if unless the clutch slips

[TuxedoRonny]

@iNeedToGetOut

Wow.

[TuxedoRonny]

Japan sounds like it has a lot of interesting museums...

[paskahousus]

this just shows what clutch does... not how it works

[abcd19263]

when the clutch disk is lifted off the flywheel, does the input shaft stop rotating instantly like in this video?

[IRAMightyPirate]

@abcd19263 No, this is moving at something like 60 RPM while a normal motor will be doing about 2,000 RPM so it will have a lot more momentum. It will slow down fairly quickly, though. If you're driving along and push the clutch in and then let it out in about a second you can feel that the input shaft lost some speed but not much. However, after about 3-5 seconds it's lost most of it's momentum and if you let the clutch back out you can feel the input shaft grabbing the clutch fairly hard.

[jaydnls15]

@IRAMightyPirate 60 rpm... nahh maybe 4 lol. I'm bored so one not pointlessly correct people with my bad spelling self

[mikeyboy236]

@jaydnls15 Close.... 1 revolution every 6 secs is what I got.

[shockwavevp]

@abcd19263

It doesn't. If you're in gear and you push in the clutch, the transmission/clutch assembly will move at the speed the wheels are moving. If you want to change gears, this is where syncros come into play. The syncros will take a moving input shaft and adjust the speed so a gear change can be made.

The only reason the transmission stops moving in this video when the clutch is pressed is because there are no wheels attached (in a rolling vehicle, the transmission is always moving).

[jacktheripper0194]

@shockwavevp that is why "big trucks" have to double clutch to adjust the shaft because there are no syncros... just random knowledge :P

[0utcastAussie]

@jacktheripper0194

It's actually "Double de-clutch" which used to be the norm on constant mesh truck transmissions (Lighter and more robust), however, so many n00bs have joined our industry that nearly all trucks now use Synchro trans. Our own fleet are now full auto's. Unbelievably the noobs still ask to be shown how to use it !! Eaton twin splitters being a brilliant mix between the two. The old skills are being lost.

[jacktheripper0194]

@0utcastAussie ah... my dad was going to teach me everything he knew but then he sold his truck. I have gone with him ever since I was 13 I am 17 now. If you are wondering why my profile says some random age it's not "my" profile it's my cousins lol. But you are very knowledgeable in this industry good for you :P keep it alive!

[chromeharris]

This shows a 2cyl crank with a hydraulic/cable clutch engaging an input gear only main-shaft through a diaphragm spring (presumably) pressure plate (hard to see) which moves power to the counter-gear w/ 2 speed counter-shaft (non-engaged, normally would support 2 speed gears and synchronizer/shift-fork on the main-shaft) which would normally power the differential or transaxle. The straight cut gear closest to the input is the flywheel which is attached to (turns at same speed as) the clutch.

[ddawg98]

what is the rod that the slave cylinder pushes ?

[Gopeshkabra]

gr8, thanks.! O:)

[Shaker1978]

VERY nice !!! No simplified animation, but a REAL working clutch in action. Thanks!

Explanation: When you press the pedal, the release bearing (small round, silver thing next to the black pressure plate) presses a spring mechanism inside the pressure plate, and then the pressure plate stops pressing the clutch disk (inside the pressure plate) towards the flywheel (with teeth) The transmission on the right is ONLY connected to this clutch disk!

[thegoonist]

@Shaker1978 how is the engine connected to the gears on the right? i dont see any "drive shaft"?

[Shaker1978]

@thegoonist The gearbox is simplified inside. Most gears have been taken out to visualize the way of the force better. The gears on the right are not "connected" to the engine. They would be connected to the shaft that goes to the wheels outside. This is the "exit" of the gearbox then. The "gearbox entering shaft" (??) is more or less invisible here. The only thing you see of it is the single gear on top of the others.

[thegoonist]

@Shaker1978 dude, i really appreciate you trying to explain this to me but this is only making me more confused XP. i wish there were a better explanation of all this on youtube. =(

[Shaker1978]

@thegoonist Take it this way: This video is very good to show you how a clutch works. It is not good to show you, how a gearbox works. Focus on the clutch mechanism and keep in mind, that the thing on the left is the crank shaft (engine) and the biig silver gear is the flywheel where the clutch is monted on. The black "cage" is the pressure plate and always rotetes together with the flywheel. The flat clutch disk in the middle only rotates when the clutch is released (lever moving to the right).

[thegoonist]

@Shaker1978 i understand this. but what i dont get is the contradicting motion of the lever. it moves away from the clutch disk and the disk starts moving? because i mean intuitively you need to press the clutch towards the flywheel so it moves together right? so the lever should be moving towards the flywheel and clutch disk, not away. this is what im confused about =) but thanks anyway!

[Shaker1978]

@thegoonist You have mail ;)

[isurfu2ube]

so when you press the clutch pedal does it press the clutch disk towards the flywheel or away i still confused?? anyone know?

[epistte]

@isurfu2ube The center of the clutch plate is pushed toward the engine, but the outer friction material moves away from the flywheel.

19927861, The slave cylinder is the small cylinder on the side with the black hose coming from it. When you push on the clutch pedal it transmits hydraulic force to the slave that pushes the fork that engages the flywheel.

[thegoonist]

@isurfu2ube yea i know right! the vid shows that the gears start moving when the disk thing moves AWAY from the flywheel when the clutch is engaged. shouldnt the gears move when the disk moves TOWARDS the flywheel?

[Elkarateka3]

@thegoonist i finally got it myself. the clutch is pressed on the flywheel by the pressure plate when you press on the clutch pedal the clutch fork press the trowout bearing into pressure plate but it does the opposite it realease pressure there for the clutch disc moves away from the flywheel and allowing you to put in your gear. thats why the tranny gear stops moving so you can select the gear. hope you get it. :)

[thegoonist]

@Elkarateka3 lol i cant understand you. your english is quite terrible honestly. still dont get it =/

[19927861]

were is the slave cylinder

[DanieLaixer]

I agree with these guys, pefect!!

[mayank8716]

amazing...very nice video dude.....its pretty clear now how it works...thnks to u

[dimgt]

Awsome vids! Live in action is so much better all the time!

[keoyauco]

yes agreed. Thank u very much

[ovy86]

very ilustrative!! thanks a lot!!

[snowman4839]

THANK YOU! someone who finally made a good clear video on how a clutch works in action
