Audi quattro::torsen differentieel

[AhmadAboulFarag]

The worst thing about worm gears though is that they reduce efficiency......still good idea....

[mathlers]

I only realized at the end of the video that I couldn't understand shit...

[marcvie9]

the discription is chinese , the video is dutch, the comments are english  WHAT THE FUCK?

[DylanRacer]

@Lamboragon spreekt vlaams

[dasawan]

sprechen zie english

[MoneyMakingForFreee]

het duurde echt kei lang voor ik doorhad dat hij mijn taal sprak

[MrBobbob69]

Is this why I don't see any quatro's on the road anymore ...

[tomview1]

Like an Eaton with the pinions at 90 degrees. Looks like it works well.

[tomview1]

Like an Eaton with the pinions at 90 degrees. Looks like i works well.

[rcoil84]

What did he call me?

[quetecojaunburro]

It is an atomic geared bomb with self destruction ability. OH my God!

[Wisdomspeeker]

Why is this in an asian language, The Japanese or whoever can put it on youtube and the Germans cant?

[Snelselen]

@Wisdomspeeker it's dutch

[Wisdomspeeker]

@Snelselen hehe, i guess ive got misled by the writing in the description.  My bad.

[Quattroowner]

@Wisdomspeeker you are a crazy guy , this is an asian language ??? It´s dutch ...

[Wisdomspeeker]

@Quattroowner Dutch is a fairly foreign language to me. And the writing in the description is CHINESE.

[Jer0mmel]

Thanks !

Duidelijk zo visueel.

[mrgears]

The Torsen differential, invented by the Gleason Works in the late 50's, sold to Zexel in the late 70s where it was vastly improved upon.

[200293mk]

nice



[mccarterjg]

how much more it costs to machine that rear end instead of the simplicity of a old ford limited slip

[MrLowAltitude]

@mccarterjg Take an old Hummer H1 axle, they have a torsen rear and front diff ;)

[mccarterjg]

@MrLowAltitude no i would pick the torsen over any other style locker but just stating the machine and molds and precision it takes for the pinions to all have the same tolerance to come in lock up contact at the same time in mass production, vs some sand blasted cast spider gears and a clutch pack and a spring.

[imaniket4u]

but where's the input shaft from engine????

[IMDRock]

@imaniket4u I think the power comes in by rotating the worm gears around the center axle, then the worm gears spin against each other if one wheel is going faster

[etmax1]

@imaniket4u I think this is the diff on the tail shaft between the rear and front wheels. Basically a diff connecting 2 diffs :-)

[chevguy502]

@imaniket4u unless your a mechanic ..... dont watch this video

[WhiteGravey]

@chevguy502 and can understand it -_-

[staufinc]

@chevguy502 why would anyone have to be a mechanic to watch this?

[guyfromboracay]

dinger ddangger doonger ja!

[UltrAslanli]

pff ingewikkeld

[MAXENFORCER1304]

Use the international language please.....

[Cougar545x39]

This is nice, but pretty expensive to make.

[revorocks123]

Torsen diffs are amazing, very clever design!

Amazing how you can implicate such a basic principle: a gear can't turn a worm gear...

[COD5252]

they cant transmit any power

[codyxcaution]

And I thought a standard was confusing...

[1MtnBoy]

this is normally used as a "Center" differential to control the torque split from front-to-rear in a AWD system.

AM general uses them in the front & rear axles as well in the H1, which of course means riding the brakes if you lift a wheel under power.

[Victor1234979]

the engineering art! I love it! this is the most graceful creature engineering!

[oilyear]

Is this the split diff to tranfer power from D front to D back for 4wd? I don't under the speaker.

[RaGeBbit]

@oilyear Could be if you want. It is used on axles as well. Hummer is a good example. This diff work as long as the sliping wheel has some traction. If the wheel is lifted, this diff becomes open with an important difference: You can reproduce the traction with brakes.

[willthis1do]

Well that cleared that up!

[syvrin]

Good for you Teschtescht! I always appreciate truly educated people putting the "children" in place. The internet is rampant with nay sayers and people speaking of false truths. Although I am not a avionics engineer I am a new physician, so I can at very least grasp what you guys are talking about. It doesn't matter if its this or things in my field there are always those you'll have to correct...time....and time...and time...and time again. Bravo!

[midlanthony]

wtf is the point of the design

[ht666th]

No point.. Germans are dumb. Seriously.

[csmaster65]

And latvians are ignorant? And besides, they got owned by the germans some time ago.

[ht666th]

Thats an excelent example of their stupidity.

[csmaster65]

Yeah, now i realize my ignorance.

[ht666th]

good for you

[Teschtescht]

Shut up, you're just jealous!

[ht666th]

of what?

this stupid design?

[Teschtescht]

You just call is stupid because you can't understand how it works. ;)

[ht666th]

It works exactly like any other differential only germans make it look more complicated for others to think they are "so smart and supercool"

Germans created veyron. That shows everything about their minds. And as one you probably wont even see my point and keep buggin'

[Teschtescht]

Here we have the proof that you don't know what you're talking about. It works NOT like every other differential!

The difference is the use of worm gears instead of normal, straight cut planet gears. Worm gears have a self locking characteristic caused by the friction due to axial forces. So this is a fully automatic, pure mechanical self locking diff. Very fast and very though!

[Teschtescht]

Well... Yes! =)

[ht666th]

hmmm. that proofs that you are a GERMAN LOL!!!

[Teschtescht]

Actually, that proofs again that you are stupid... :P

I'm not a german, I come from Switzerland and I'm proud of that. ;)

[ht666th]

and thats the same region as germany. so fuck off. i have made sure that german region guys all think the same way. go and get educated somewhere.

[Teschtescht]

Hi

Well, I think my educational level isn't that bad, probably better than yours. I work in a development department of a vehicle manufacturer and besides my 80% job I study electrical engineering. I also worked as a F/A-18 avionics technician for the Swiss Air Force. So there are a few things I know... ;)

Oh, and you can talk normal to me ok? Things like "fuck off" are pretty pathetic.

[ht666th]

there are always exceptions. but occasional. and mostly rare. good for you. but nothing beats the educational system in Latvia. We are forced to absorb way to much than we will ever need.

[Vedad24]

well if you think that then mexico is as same as usa region.

[ht666th]

i do think that but ur conclusion was wrong.

[Cougar545x39]

@ht666th ..somewhere you didn't

[kiefer1234566767]

@Teschtescht

whens trail gear comming out with one

[zazon5]

@Teschtescht Worm gears are only self locking if their efficiency coefficient is less than %50.

[HighEndComment]

@charlietow woop woop spelling police

[Teschtescht]

@midlanthony

The self locking character of the diff.

Worm gears are self-locking due to their friction. So this is a fully automatic, pure mechanical self locking diff.

Very fast, reliable and tough! This is the reason Audis Quattro system is so good.

[RDMracer]

zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz­zzzzzzzzzzzzzzzzzzzzzzzzzz oh shit fell asleep it's an completely senseless solution

[deaftodd]

Is a bevel gear has been omited for better clarity?

[deaftodd]

how do they connect the shaft to it?

[bestamerica]

why need it

[floringguy]

it's a regular differential... vry probably the development gone to on a cheaper system, like hypoid drive... that still the most expensive... and most difficult.... a helical gear even can be made in a homeshop...

but as the weakest link was in the orig conception the shafts in the middle gears, in this the weakest the point where the small helicals are connecting to the mini spurs... probably it is for some toys...thanks

[deezynar]

floringguy, I don't understand what you're saying.  Can you explain?

[floringguy]

to producing the two type of gear very different.... a "conventional" hypoid gear, a difficult process... a heligar gear relatively "simple"....

[deezynar]

Thanks for clarifying. The video doesn't show the power input including the ring gear. The torsen can be mated with any type of ring gear including a hypoid if input shaft clearance is an issue. So the cost of a hypoid gear isn't a factor related to the Torsen. Mr. Gleason, who patented the Torsen differential in 1958, also had to invent hobbing machines thought to be impossible at the time. The Torsen isn't cheap to make & is very robust. It's used in racing cars & earth moving equipment.

[floringguy]

thank you... very nice, i like it,,, eventually someone heard about gleason, oerlikon and of course klingelnberg......

might i wrong... but this was i was thinking first... for helical gear, the pfauter the fastest, and same way can be ground... that was i thinking... i did not know gleason find it out... (shame on me )

any way thanksto clarify it me...

[deezynar]

floringguy, I am very happy to have been of any help. I don't know much about Mr. Gleason, but the little I do indicates he was a great genius. He solved the problem of slippage found in the standard differential that had illuded thousands of other great minds before him. To do it, he imagined a mechanism in his mind that makes no sense to most people even after they have seen it!! Amazing, the man & his achievement.

Best wishes to you, floringguy.

[deezynar]

I was just reviewing a bit of information on the Tosen differential and realized I had made a mistake in a previous comment. The inventors name is Vernon Gleasman, not Gleason. Mr. Gleasman invented and patented the idea and later took it to a large manufacturer of gear components, the Gleason Works. The exact history is available on-line for anyone who is interested.

[bigmacattack05]

if there was a passenger he'd be dead, this car is a piece of shit, the driver is one lucky son of a bitch

[corotor12345]

ok... first of all, what brings you to the stupid conclusion that THIS is a car? its a differential, a mechanism that lets you corner, period, no car, no shit no nothing. dont hate on stuff you cant understand

[SpeedViolent]

irka6utu , polla 8es...

[trickybloke]

Yeah i spend a fair bit of time in Amsterdamn blazing up big spliffs and blasting a few brasses up trap 2!!!!

[nima1234]

im with ya

[Rednaaa]

Sztem vannak itt gondok rendesen! Kanyarodáskor ez el diferál,ezért erre azt találták ki a nagyok hogy le kell hegeszteni !!!A kis kerekeket kell egymáshoz+ a házhoz hegeszteni így javúl kanyarodáskor a kocsi stabilitása,mert keresztben csúszik,csak driftelni lehet,ez köztudottan kurva jó :D PL:(LADA,de abban sokkal jobb difi van)

[elbowka]

a torsen nem differal le ;) ez benne a plane. torque sensing = nyomatek erzekeles. oda megy a nyomatek ahol tapad...

[Philscbx]

Yea, The Dutch are darn funny, I spend a lot of time with them at the bar spilling massive quantities of foam in Amsterdam.

The torsen gearing units have been around a long time since middle 70's. I was there.

[Mythix2]

he says that the cogs make the cogs rotate, and the cogs are rotated by the cogs

meer snap ik er ook ni van

[mo4life123]

lmao!

[irka6utu]

in what language is this guy speaking?!

is there anyone who can translate that in english? ...or greek, that whould be better for me!! thanks

[koentjuh5]

this is dutch, netherlands

[Csabika30NY]

alles claar!
