3D animation of dual mass flywheel

[voyteq1]

I have this problem now with my passat 2006 diesel. Vw dealer want £1000 but im going to change this shit with cheaper mechanic for £550. This small company giving me 2 years of guaranty but vw dealer only 1 year. Its a joke...

[onlycodered]

Just got a new Mustang V6 and have found out that it has a DMF apparently. Judging by the comments on this video I'm sure I'm going to be in for a fun ride with replacing this garbage when it breaks...

[IRONnTiTAN]

this is to limit drive line vibration, look up "350z clutch chatter" it quiets shit down quite a bit and I have heard it's not as harsh on your synchros.

[skatesneakerlover]

Agreed kevrs2. He needs a HARD beating with the same piece os SHIT he developed and be made to eat the pieces......the worst shit they ever designed

[kjaks]

It is said that these so called dual mass flywheels fail faster when the car is driven at low rpm's in higher gears (3,4,5) with a lot of throttle. Like when doing 35 mph slight uphill in 4th gear with 50%+ throttle. 3rd gear and 40% throttle is a better choice in such situations to maximize DMF life.

[WolfDog375]

I wouldn't buy a car with a flywheel that costs over 500$ even if my life depended on it...

[BigBlackMamba101]

@WolfDog375 You must drive peace's of shit then.LOL

[WolfDog375]

@BigBlackMamba101 If you make a Jeep Cherokee a piece of shit then, yeah, at least it's not of those crappy VW or Seat's ;)

[BigBlackMamba101]

@WolfDog375 I take it your Cherokee must be a 1990 model then? LOL.

[WolfDog375]

@BigBlackMamba101 Yeah close to that, 1992, old but runs great, doesn't really matter what car you drive, what matters is if you like it yourself or not, tastes differ. Just don't like the fact that newer cars use more complex mehanics, which make them harder to maintenance and repair and more expensive. But if someone likes the dual mass flywheels, it's his choice and his funeral. Neighbour changed the DMF on his Corolla this year, about 400$, better fill the tank for that money...

[isotopicdreams]

32,000 miles that was by the way! Bloody apple autospell! Lol.

[isotopicdreams]

I'm gutted reading all this now. My ford s-max is right now in a ford dealers. Fly wheel naffed, new clutch is imminent too. £1400 that's bollocks, £32,000 a new flywheel. That's bullshit! Surely hear counts can be taken to court.

[webtrekker]

Superb animation! Shame about the concept though. More moving parts, therefore more likely to break down IMHO.

[baggyaxewound]

i know nothing about this, first one ive seen , but cant you just change the springs inside ?

[littleninjai]

Thanks i was wondering what dmf stood for as mine just broke. thank god its under warranty. darn u high torqe desel.

[truemtv]

fajnie, ze sie postarales, ale kots nieobyty w mechanice nigdy nie skuma tej animacji, dla lamera jakies kolka i sprezynki sobie kraza i lataja, proponuje dodac kilka plansz z opisem.

[mrderwoz]

real shit,its gone on my ford mondeo and cost me fortune to get new one!

[GrimlyKK]

What a fucking dumb concept that is. Thank you, Ford, VW, Volvo, et al, for being a bunch of cocksuckers who couldn't design a paper bag if your lives depended on it.

[ChuffChuffWoo]

You need one of these..... :)) youtube.com/watch?v=wGYH84dsNp­U&feature=autofb (don't forget the 3'W's at the betinning - youtube doesn't allow the whole link to be posted at once - don't know why...

[ChuffChuffWoo]

Crappy stuped DMF has gone wrong on my son's car - fortunately I have a Prius - the most reliable car on the road - thanks to the elimation of all this mechanical tosh, in favour of solidstate electric drive.....

[copterdoctor2000GTP]

@ChuffChuffWoo

you clearly haven't been checking the reliability status of the Prius have you? Not quite as reliable as your arrogance would suggest. It's not bad but it's not great either, especially this last generation. You might want to check into the regenerative braking system issues your car is known for.

[ChuffChuffWoo]

@copterdoctor2000GTP What braking issue?? Overhyped press reports apart, the brakes are first class - my 10 year old Prius still goes like new - I'm so glad to be rid if all the mechanical junk that makes all other cars so problem prone - like the idiotic DMF madness

[2strokedetroit]

@ChuffChuffWoo unfortunatly you will get terrible mpg when the batteries lose their charging efficiency

[ChuffChuffWoo]

@2strokedetroit Honda have had problems with this, Toyota seem to be ok - my 10 year old Mk1 Prius is fine.

[2strokedetroit]

@ChuffChuffWoo wow that's hard to beleive. I hope they stay good for a while. I hear they are ungodly expensive to replace.

[ChuffChuffWoo]

@2strokedetroit MK1 batteries are said to go at about ten years - mine are ten years old - eeeek! ;-) The problem is them 'drying out' inside due to tiny mosture loss where the terminals pass through the plastic battery cell cases., Toyota have continued to improve the design, in effect, giving the world an almost everlasting battery - the MK2 and current MK3s don't have this problem.

[ChuffChuffWoo]

@2strokedetroit PS -a new battery here in the UK is £1300, I think when they do go, I'll just upgrade to a newer Prius - more power, space and economey, then with the new car to drive about in, I'll just swap out the duff cells and sell it as a runner - especially as it still looks and drives like the day it was made - bar the odd scrape!. The car gives plenty of warning of iminant battery failure, so I've got plenty of time to act if there is a problem brewing.

[baldandold]

remember guys, most OEM DMF's are made by LUK "down to a price"

Try to source a SACHS unit and good 3pc clutch (Borg and Beck)

ive heard every excuse under the sun for the use of DMFs

Body vibration

Diesel torque peaks

Transmission breakages

Try finding ONE example (proven) of any of these, its all BS

[peaceman1234567]

Pain in the fuckin arse.Alright if your doing average miles but if your doing driving for a living its a big fuckin stupid cost to replace the starter motor,the flywheel and the clutch plus vat and labour.These things break,fuckin shit.

[maestroadam]

absolutely fantastic animation.

[peaceman1234567]

@maestroadam absolute pile of shit you mean.Fuck the animation.Steam engines are much finer machinery than this fuckin garbage.

[2010jimmy2010]

dont forget folks, if your dual mass flywheel gives up, and you are not sure what to do, you could always hang yourself!

[KapteinOpel]

pointless

[brettwill87]

i just had a dual mass flywheel break on my van so i had it converted to a solid flywheel. far more reliable and if either my clutch or flywheel breaks in the future i've only got to buy the part which breaks and not the two.

[tylertyler82]

This is the second dual mass clutch system I am having replaced and my car only has 92,000 miles (that makes 3 clutches all together) Cost to me: Over $2,000

[pajo1982]

So it's basically a low pass filter on your car's transmission? Sounds good. Why, specifically, are they prone to failure?

[mikerjuk]

@pajo1982 It's exactly that, a mechanical low pass filter. They have coil springs and sliding surfaces that move on every engine rotation, so they have to endure hundreds of millions of cycles whilst also transmitting the significant torque output of a turbo diesel engine (though many petrol engines now use them as well). Broken springs and general wear are inevitable.

[kevrs2]

who ever thought of this piece of shit needs a good beating,all it does is turn a not that expensive clutch chance into a mega expensive clutch change it seems the solid flywheel was just to god dam reliable

[ihavcndygetinthevan]

lmao funny shit

[activedentalfloss]

@kevrs2 yeah, you're right. I'm dreading my golfs clutch failing, it'll be around £1000 to get it fixed. They should keep things simple.

[kevrs2]

there are cheaper ways round it ,you could fit a solid flywheel for and earlier model ,or what you can do is get a machine shop to weld the dual mass wheel solid and fit an earlier model clutch plate ,dont give them anything ,do the cheaper option good luck

[jjrdrifters]

@kevrs2 yeah but as modern disels have more torque are standard clutchs cant take it so thats why thy made to dmf

[3DPeter]

@jjrdrifters

Bullshit! It's just like kervs said, it's only another way to rip some more money out of your pocket, because

when they can make clutches for giant trucks, than they can make them for any goddamn car.

And the only thing that changed at the clutchplate is that became a solit plate by taking out the springs that catches the off an on going forces, and built that into the flywheel so that that piece of shit can wear out too, because no one ever needed a old fashion new flywheel.

[eatthisvr6]

@kevrs2 this!!

[hyweltthomas]

These things are absolute junk, mine has gone again taking the starter motor and clutch with it. I would never buy another car with one of these things fitted.

[russ0r]

They're a necessity for torquey unrefined 4-pot diesels. If your diesel didn't have one of these it would be horrible to drive or be driven in.

[hyweltthomas]

I disagree, there's been 100 years of normal flywheels in diesels - on torquey and non-torquey engines. The web is riddled with stories of how unreliable DMFs are. I have just picked up my 02 Mondeo today after getting the DMF replaced with a non-DMF retrofit replacement. These problems have so far cost me £2300; it's a shame Ford don't have the same recall philosophy as Toyota. They won't see my pound notes again.

[petterz13]

@russ0r oh really ?

[noobsound]

bleah mine is pretty much done on my vw t4 2.5 150ps and with the clutch kit costs more than 1k euro. Hate them

[wstnets]

i have a dual mass flywheel that the dealer say they replace 2/3 when the do the clutch in a Holden 2006 ute

V6 195 kw 6 speed

I want to put a single mass flywheel and clutch in just wondering if it will cause me any more dramas

[MPistol]

thank you! this is exactly what I'm removing from my car - haha

[paragonx88]

cool trippy vid, but i still dunno what is going on lol..

[baldandold]

a nice earner for garages....

[peaceman1234567]

@baldandold absolutely,its mechanics dream this is.Get a stupid bunch of design engineer cunts who have to change something that isn`t broken and we are all out of pocket.

[laldog]

@peaceman1234567

Hang on,it aint the mechanics fault if the poorly designed part fails. Its the manufactures that should be blamed.

[AussiePride2439]

@laldog

These clutches are great for those who control their left and right feet and make the car much better to drive. If your dropping the clutch and doing duelies everywhere then nobody is to blame but yourself. If you have an car with one for example (ss ute) then buy a solid flywheel conversion and give it the fat everywhere.

[elemineseslapolla]

hmm this looks like crap, Not the animation which is amazing, i mean the flywheel, way to much moving parts = messy shit if used for a long time, its like a 21 in 1 product always fails after short time :S

[skroper]

DMF - I own one on a 1 ton and looking at replacing it AGAIN... Not Tough Enough.. Period

[cityslickers777]

I love weetabix, i put the milk on them and them microwave them for 1 minute... mmm yummy

[nofunnyname2]

Great, thank you. I wish there were more brilliant explanations of things like this.

[moondog637]

Good concept bloody stupid idea in practice.

[Spanielsfr]

And how do you work that one out then genious? Working for SACHS i know a hell of alot about these things, and it really does piss me off when we have stupid arse comments like yours above as to " why do we need them?" if you read up on it then maybe you would understand! DMF's are there for a reason!

[hyujkokozy]

considering their expense and how long they last, they should be an optional item. You dont see them on rugged 4x4's because they are crap for heavy driving. I believe this is a method of fixing a failed design, making a smoother engine should be the priority, but I guess using 100 yo technology was doomed at the start anyway. Engineering is all about keeping the broadest market happy. DMF dont do that. Good animation.

[mikerjuk]

DMF's are clearly used for a reason, primarily to improve refinement. However, taking an inherently reliable component and making it complex, unreliable and expensive appears to be the norm for todays automotive engineers. Crappy electronic indicator stalks and electric handbrakes come to mind after DMFs.

[lewis72]

Don't blame us engineers, blame the customer (via the cost guys) for going for the cheapest solution.

[peaceman1234567]

@lewis72 hey pal,you know what,there`s nothing cheap in forking out upwards of £800 to replace an unbelievably unreliable as this dual mass flywheel is.Its nothing other than a pile of junk in your car.

[Tiffx19]

I've changed 3 in a week at work, all on fairly low mileage,low powered cars.. Valeo are expanding their range of solid flywheel conversion kits..guess which kits the customers are asking for?? Stupid bloody idea.

[NomenNesci0]

Funny but after seeing the video I now know how to make this system as reliable as a normal flywheel and the dampening will be more efficient.

A bit more expensive though.

[hoshy81]

Very useful, thank you!

[skyuen9]

Very nice animation.

The core reason for the Dual mass is to act as a mass damper on the transmission to change the frequency response. The spring is to lower the stiffness which can be done using a normal or long travel damper driven plate.

[Sindrey]

Excellent video, really helped me understand what they do and how they are put together. Thanks Filip. What are the common failure point's with Dual Mass Flywheel's? I wonder what long term solution there will be for these

[wilkiesenior]

good an many thanks still.... bloody stupid idea because of that bit of engineering it just cost me £1500 from volvo to do my clutch on a 05 s40 136 bhp 2ltr d, and it still isnt right looks lke the NEW DMF will need replacing! and bits have just fallen off after 2 miles yeah progress

[eradeziel]

Fatastic, such a simple design. Cancels out a lot of vibration through the drivetrain, great for refinement.

Quality video.

[peaceman1234567]

@eradeziel fuckin shit,its an arsehole design,costly, pointless and shit.

[eradeziel]

@peaceman1234567

Its not pointless at all. It makes a car far smoother to drive, particularly those with fewer cylinders. You only really find them in more presige cars or diesels anyway. Admittedly I had a BMW with one and in the end I switched it for a regular flywheel, I prefer engine response over smoothness. But if you like a car to drive smoothly, which most people do as they're not really into driving, then you'll see why manufacturers fit them.

[peaceman1234567]

@eradeziel yeah but pal,its the cost of them when they break.Its ok if your an office worker doing not much over 12,000 miles a year in your BMW or diesel powered motor,the expense esp if you can afford it isn`t that unreasonable.But it is if your a cab driver doing 90,000 miles a year and earning a whole lot less,these rubbishy flywheels break more often and put you in real hardship forking out for the piece of trash.

[eradeziel]

@peaceman1234567

Yeah I do take your point, they are expensive when they go wrong. How about a retro fit single mass flywheel and clutch, or a model which doesn't have one fitted in the first place? Also, some makes are much less prone to DMF failure than others. I qualified in auto design engineering, and its a shame that cars these days are literally made as a huge series of compromises aimed at the masses.

[eradeziel]

@eradeziel

They are just businesses at the end of the day, and none are really in a position to appeal to all needs. I gave up on newer cars ages ago. I drive older cars, in 99% of cases you can fix anything that goes wrong yourself. Nothing more complicated than it needs to be, no fancy equipment to go wrong. They only ended up that way in the first place because of often unreasonable public demand and competition from fellow manufacturers.

[peaceman1234567]

@eradeziel The old design was the best and to be honest cars made now are smooth enough to drive without these new flywheel designs.I`m not against advances in engineering,that`s why we`re not driving around in 1920`s Model T`s, but it has to be reliable and reasonably affordable.

[mosquiton001]

Good explanation I finally understand why bad DMF cause vibrations and noises.. (especially in VW and AUDI lol)

i use 3ds max too! I made some movies and trailers tahat you can see in my channel! just love 3d animation..

[drk2948]

Great learning.Thanks

[billihoCanada]

Great video. Thanks for the lesson!!

[al138]

great video

[DoD511]

It's good for learning about dual mass flywheel,thank you for your video.

[wilkenas]

Thank you for this video. It greatly helped understand DMF

[BigBadPea]

Great video, thanks

[ecurveman]

What program did you use. I am tring some animation in a cad progam but the resolutes arnt quite that good.

[FilipKaczorowski]

For the animation, 3D Studio Max 9 and Solid Works 2007. It is my first contact with 3D Studio Max, but the resolutes is very good:)

For the video, Ulead Media Studio 8 and Ultra Video Converter. Originl video resolution is 800x600 and 4GB size(frames not compresed ).

[CaptainGrimes]

I suppose it's easy to follow the animation if you already understand how a DMF works. (sigh)

[ChrisIdzerda]

A DMF is a DualMassFlywheel found on VW's starting in about 1999.5. Very smooth shifting as even if you are not very good it will absorb the off speed.

[kennethsross]

Excellent demonstration of how a DMF works and what it does. Will always direct folks to this clip when they ask "what is a DMF?"

[peaceman1234567]

@kennethsross DMF stands for DAFT MACHANICAL FLOP.
