Good job Thomas, i live in turkey and automative student.I was in a lot of trouble with it because there are not enough resources in Turkey. Thank you man. I wish you continued success :)
Brilliant work , be nice to mention a few other elements ( 1 ) friction material sometimes cork ( 2 ) sometimes in an oil bath , to remove heat ( 3 ) may be used to reduce overall diameter .
Thanks man, I was really stuck when I was studying and was in doubt why torque increased but the force remained same in the equations for multi disk vs single disk clutch.. after seeing this i finally understood..
The video is very good and clears all the things with a very precise animation :-) My kind request is you can try to duck the sound of background when the narrator is speaking because the background music is bit too loud which makes it a little difficult to concentrate on the narrators voice ... but the overall video is excellent ..Kudos (y)
@@herkko61 my tolerance for it is up pretty good after watching professional TV at the doctors and they did it worse. Lol. I've done this with music a bit on my Automotive videos, but I'm very careful. I recently uploaded a wet clutch slip problem and fix if you're curious.
Thanks for sharing these videos for free Thomas Schwenke, for me, I work, study and am a father, is helpful. You are doing a great job for the society. thank you alot.
+indraidabagus the engine is on the left if this is inside a Ducati motorcycle. Your question is difficult to answer because there are so many applications and most clutches can be used in either direction. But, to give you an example, look at a Ducati motorcycle. The shaft on the left of the animation would be the shaft inside the engine connected to the piston rods. This means the inner plates are spun by the engine and the clutch transfers the rotation to the plates with the teeth on the outside. Then that can be used to turn a belt that then spins the transmission and finally the tires. So the most simple answer could be to say "engine on left" but because of the endless possibilities he didn't want to say it as a blanket statement.
I 'really' learnt a lot from this clip. Friction between 'inner teeth' plate & 'outer teeth' plate......... As I didn't know about teeth difference, I always thought "what the heck is the difference between engaging/disengaging those packs?"
This actually works almost exactly like the wheel brakes on commercial aircraft, the obvious exception being the use of friction to reduce speed rather than transmit power.
Thank you for the great explanation. There's one thing about multiple clutches that I don't understand. These clutches sit together with the gears in the gearbox and run in oil. Even though the friction disks and the steel plates are pressed together, why don't they slip (because of the oil) ?
When the pressure isn't applied the metal plates and friction plates magically separate... Every video I've watched never mentions how the plates seperate and why they don't continue to stick together after the pressure is removed...
Hi. my 520i f10. While decelerating at 20 km/h, the car downshifts, and if I press the accelerator immediately, it makes a hard movement and starts accelerating. I wonder if the lock up clutch comes into play? It only does it when it's hot. thanks
Hello .. I have a question that at the car clutch the disengagement is 1 mm for small engines and 1.5mm for the big engines but what is the basic cam properties that usually used for this .. what is the distance between dome of the cam and the cam basic circle ... or what is its table .. f(x)=??? ... and what is the spring K(N/m) constant .... ... after I did some not much presiced calculations I can imagine while pulling the clutch handle of a motor bike small engine: like 125 cc that it is like pushing 500 kg isn't it ? Thank you !!! :)
So..what's the benefit of having multiple plates? Are more plates necessarily better? Most racing applications I've heard of use multiple plates..does that mean they're not recommended for daily driving? Are they harder to press down than single plates? Any info is helpful thank you
They're not necessarily bad for DD, they're typically just lighter and more compact. This comes at the cost of complexity, which decreases part life and increases maintenance costs. They can also be used to transmit significantly more power than single clutch plate systems.
You can clutch less shift....if that's what you mean. Pre-loading the shifter, while momentarily letting off the throttle, and ill pop into the next gesr no problem, but to "powershift...AKA quickshift. You need a quickshifter, or a power commander/ Bazazz with quickshifter...If that helps
Does a one plate clutch have to be so heavy to have enough friction that disengaging it would be too hard for a system that wouldn't be bulky and heavy for a motorbike? Is this why single-plate clutches are commonplace on cars but I've never seen one on a motorbike before?
+junoguten I assume it's because single-plate clutches require a much larger radius in order to get the same leverage. Even if they were lightweight they'd be far too bulky for a motorbike.
hello thomas, what is the advantage of multiple clutch over single clutch plate? What is the purpose steel discs between friction plates? I dont see any advantage?
have 1976 Triumph Bonneville which was rarely used(1128 miles)Sometimes it starts without any problems on kicking(one kick)..However lately in trying to kick start the crank does not rotate on pushing down. There is severe resistance like grabbing(in neutral of course) on kicking down..DRIVING me NUTS to figure out!! HELP SVP
Excellent Video. @Thomas Quite often my Bike Clutch Plate Eradicates, that is the friction does not work, resulting in low acceleration and some time no speed above 30 km/h, in that case i have to change my clutch plate [Changed already thrice] My mechanic told me it is due to half clutch, my question is why does it happen and how does it happen and how do i avoid it?
the explanation in the video from time 1:57 sec. is said vice-versa with respect to the animation. Can you correct it? So when the friction plate and steel plates are pressed together power is transmitted And when the plates are not pressed together power is not transmitted. So can i say that the working of multiple clutches is opposite to working of single plate clutch. since in a single plate clutch, when the diaphram spring is pressed the power is not transmitted and when it is released there is power. (NOT THE PRINCIPLE OF WORKING)
+Reilly Brunette my guess: multiple disks means increased surface contact which can hold more power with less friction per disk compared to an only two disk clutch. that implies less wear and smaller clutch unit.
Hello, I will be glad, if you could tell me from where I can download the 3D model of the clutch you are presenting. Thanks in advance and great video!!!
The information in this video, while detailed, is wrong. A clutch is engaged when it acts as a "clutch," allowing slip between a torque point. A clutch is disengaged when it acts as a solid unit. Also, if the springs on his pressure plate acted as they do in the model, the unit would be engaged at all times due to the spring load from the return springs! This clutch would literally require you to operate it backwards leaving you holding the clutch to drive!!
1) "A clutch is disengaged when it acts as a solid unit" Wrong! The clutch is disengaged when the input and output act as 2 separate units, i.e. not connected to each other. Another matter altogether is when you disengage any outside influence (i.e. release the clutch lever or pedal) and the clutch acts as a solid unit but that is NOT a disengaged clutch but just a play on words. Even the very meaning in the dictionary will tell you that. (to clutch is to grab hold of something) 2) The model above is exactly how many motorcycle clutches work and the clutch is engaged (input and output spinning as a solid unit) at all times unless you pull the clutch lever (or pedal) in in which case the clutch push-rod pushes against the clutch hat (via a bearing) thereby releasing pressure on the clutch and therefore allows the input and output to be independent of each other.
+Thomas Schwanke thanks for this and the other Videos. One question tho: If I pull the lever on my motorcycle, I engage the clutch. But your video shows that with the rod, you pull them together. If anybody else knows it, please leave a comment how it works, thnk you.
l forgot to mention that the out resistance crank turns over with plugs removed but NUTS it does not turn over and has heavy grabbing and hard to go through full kick swing because of resistance.

The music make those clutch plates look freaking heroic. Great video.
I agree with others, very clear understandable explanation about how the multi-disk clutch pack works, thanks.
I have a 1923 REO fire truck and this is exactly how the clutches work. Amazing that they had this technology back then.
Good job Thomas, i live in turkey and automative student.I was in a lot of trouble with it because there are not enough resources in Turkey. Thank you man. I wish you continued success :)
Aynen öyle olanlar da eski .
Brilliant video - i always had a basic idea how these work but this animation makes it so clear. Perfect for all n00bs. Great job!

Wow! I really liked this. Very nicely explained. I am waiting for a similar animation on slipper clutches!
So I just learned a lot from this this. THANKS A LOT!
Me too! Come check out the effect of additives on this! Does Lucas Upper cylinder Lubricant help or hurt?
Thanks for wonderful animation. Cleared concept regarding multiple clutch.
As usual. You are doing a great job to the humanity
Excellent animation.I was just confused from the diagrams and theory in the book and then i saw this.Great work👍👍

it took two videos to understand while the other videos Makes me go balls.
Thanks for your useful animation.

I have the same issue. Anyone know?
This is such a good video. Now I can take my ducati apart!
This is a great explanation and illustration. Thank you.
Very good and clear video. You helped me studying engineering, thanks!!!
Great to hear that :)
Good explanation, so it's easy to learn, thanks!
Thanks for uploading this! I actually understand because of your video!
Thank you so much for your informative post, Mr. Thomas Schwenke!
Any idea on what the issue would be if the clutch would not disengage/catch the friction zone? I'm assuming the friction discs are stuck?
Even in english, that's great. Keep going !!!

Great explanation on it all but not quite good on the disengaging of the clutches. How is the disegagement levere connected to the clutch plates
great visualization!
There's so much attention to detail! I can't wait for the next video! :D :D nice work too btw
Thank you. The next video will come soon :)
Will riding the clutch cause wear or are they spaced enough to avoid that?
nice animation information
Good work brother.... Tomorrow is my semester... Haven't studied anything... But your videos helped me a lot :) #Cheers #Champ
Great to hear that. Good luck!

What is the force required to disengage a multiclutch system as compared to a single disc clutch system
Damn, the music is too good that I couldn't focus on the video😁
wot Its just like something you hear playing in a toilet
awesome animation !!brother!! makes its easy to visualize!
which software are you using?
Thx alot. I use Carrara 8 Pro.
very well made
Just one question is it centrifugal driven cuz if i were to hold on the shifter ot would disconnected the power .My motorcyle is an honda ex5
So..what's the benefit of having multiple plates? Are more plates necessarily better? Most racing applications I've heard of use multiple plates..does that mean they're not recommended for daily driving? Are they harder to press down than single plates? Any info is helpful thank you
They're not necessarily bad for DD, they're typically just lighter and more compact. This comes at the cost of complexity, which decreases part life and increases maintenance costs. They can also be used to transmit significantly more power than single clutch plate systems.
Can i do "power shifting" with this kind of clutch without any modification with the motorcycle?
You can clutch less shift....if that's what you mean. Pre-loading the shifter, while momentarily letting off the throttle, and ill pop into the next gesr no problem, but to "powershift...AKA quickshift. You need a quickshifter, or a power commander/ Bazazz with quickshifter...If that helps

hello thomas,
what is the advantage of multiple clutch over single clutch plate?
What is the purpose steel discs between friction plates? I dont see any advantage?
Thomas... who has made this animations... beautiful illustration
+Subodhh Vaishampayan It's me!
What are the advantages of a multiple plate clutch over a single plate clutch?
Diameter is much lower.
Kain Bastien high torque
Wow those clutch plates take all of the Bresh'ah! 😀😀😀
Hi Thomas!, wich program did you use to do the animations? 3dmax? EXCELENT ALL YOUR WORKS

Thanks for all your videos! i'm so happy thank you :)
now do they drive planetary members? and can it brake or hold them?
How will the steel disks rotate??? They are attached to the case.
what are the differences of Multi Plate wet clutch vs Hydraulic radial pump clutch?
Great video !!!
Congratulations.
good
Great video!
Thank you so much for this video! You have helped me alot. SMOOCHES hun!
Excellent Video. @Thomas Quite often my Bike Clutch Plate Eradicates, that is the friction does not work, resulting in low acceleration and some time no speed above 30 km/h, in that case i have to change my clutch plate [Changed already thrice] My mechanic told me it is due to half clutch, my question is why does it happen and how does it happen and how do i avoid it?
How do the spring move inward? They are fully bolted in.
Why are there multiple pressure disks ? Why not use only 1 or 2 ?
Your videos are awesome! :)
The clutch plate's engage in the basket and the steel discs slot into the center, wrong way around but the principle is correct
thank you so much brother
the explanation in the video from time 1:57 sec. is said vice-versa with respect to the animation. Can you correct it?
So when the friction plate and steel plates are pressed together power is transmitted And when the plates are not pressed together power is not transmitted.

(NOT THE PRINCIPLE OF WORKING)
So why does it need multiple plates? On my honda I have 7, and one of them is larger than the other 6.
+Reilly Brunette my guess: multiple disks means increased surface contact which can hold more power with less friction per disk compared to an only two disk clutch. that implies less wear and smaller clutch unit.
very good and clear video
but the music is very noise with the description
Thank you for your comment. I'll bear this in mind when I produce other animations.
I don't understand how this works in relation to a torque converter.
Awesome explanation!
Sound Jay
how if the 4 friction dics are brand new, and 1 of them is the old one?
There is only one ambiguity that i see,the friction disk and steel plates got interchanged?
Is there fluid within the clutch pack?
Hello,
I will be glad, if you could tell me from where I can download the 3D model of the clutch you are presenting.
Thanks in advance and great video!!!
Great video, thank you!
brilliant. i totally understand. thanks
does a dry multi disc clutch mean it has gears (on a motorbike)
+Chantelle Smith Wet clutches are submerged in oil, Dry ones are not.
Multi disc?
Thomas Schwenke What software do you use for modeling and animating?
Carrara 8 Pro.
thank you so much thomas sir

+Dani M The rod is used to push not pull. When you pull the lever, the rod is pushed which disengages the friction plates
l forgot to mention that the out resistance crank turns over with plugs removed but NUTS it does not turn over and has heavy grabbing and hard to go through full kick swing because of resistance.
Can anyone explain to me what is a shaft to shaft mount and what a shaft through mount?
Is it aproblem if a motobike that i want to buy use to change the cluth ? Who can tell me please
excellent
the new 2019 Jetta auto has a very noisy torque converter and it uses multiplate clutches
Thanks man
Excellent.
wonder why cars do not use a wet multi plate setup?
i thought the plates where the other way round? (just watched a clutch replacement)
were
The music needs to be just a bit more louder, that way you will be completely inaudible
Could you do a video on the Hele Shaw clutch?
There are a lot of other videos that must be produced first, but I'll add it to the list :)
Thanks I needed this 😁😁😁🤘
What is he saying from 1:36 to 1:40 ?? Can someone repeat here, i can't understand
Applying pressure to the pressured plate... I Think..
great vids!
ok sir, nice
Backwards. Fiber plates have teeth on the outside, steel have teeth on the inside.
