dobry wieczór Paniwie

Co tam w wielkim świecie???

Wąski przyjeżdzam po termostat bo mi tyłek w audi marznie

[sokolnh]

Jest ktoś chętny na dzisiejsze slizganko

ja sie juz slizgałem

fajna sprawa to rwd

Eeee tam nie ma to jak Q Ja jak dorzuce bi Q to już całkiem jest zabawa

Eeee tam nie ma to jak Q Ja jak dorzuce bi Q to już całkiem jest zabawa

miałem Q wiec wiem lepiej :gwizdanie:

[Cuber]

Q jest kiepskie Q jest do d.....

[sokolnh]

Q jest fajne, bardzo i dobre na śnieg

dlatego szukam dla siebie B2Q

ale do zabawy lepsze jest rwd i tyle

[Cuber]

Kamil, wszystko zalezy co dla kogo jest zabawą i na czym ta zabawa ma polegac

[sokolnh]

na tym

[Gość PrZeMiAn]

na tym

Szkoda że za takim fajnym silnikiem taki kiepski driver

P.S. To już wolę Trzeńka oglądać na dachu galerii

[KERCZI]

jesli wierzyc opisowi to jest odpowiedniuk Q Audi ktory to niedorasta do piet owemu koncernowi

[sokolnh]

nie wierz

poza tym nie wiem czemu nie dorównuje Q ? już kiedyś to tłumaczyłem :doh1:[br]Dopisany: 16 Grudzień 2009, 22:18_________________________________________________prosze:

już mówie, albo lepiej jak przytocze cytat:

My official position: Torsen good, Haldex good. Each has it's own merits. My personal favorite - quattro-I which used a locking center and a locking rear diff. Now for the dissertation on differentials....

Haldex is effective - a very effective computer controlled clutch system that beats any Viscous Coupling system since it locks up very quickly. From my understanding of the Haldex it biases the torque evenly 50/50 front/rear and this is ideal for cornering, helping keep some balance in the car w/ regards to over/understeer. The downside - it DOES take some time to react to slip and engage. It is also VERY dependant upon electronics and we ALL know how well VW/Audi electronics age

Torsen is a very ingenious little device - mechanically redistributing torque to the axle with the most available grip instantly, biasing up to 80% of the torque front/rear. This A) provides excellent straight-line grip in the most slippery of conditions and B)works proactively to prevent slip rather than reacting when slip occurs

The Haldex system is an evolution of the old viscous syncro system with the viscous coupling replaced by the Haldex clutch. This was an easy change since the transmission didn't have to be modified to accept a front Torsen housing - which also wouldn't have been easy to package with the transverse transaxle shape.

There are those who swear that the Torsen system is far less efficient, and doesn't react as quickly, but the Haldex system still spins the driveshaft at all times, so it can't be much more efficient.

Actually Torsen quattro does not allocate power to each individual wheel - in most cases it distributes torque between the front and rear axle. In the odd case of the V8 quattro 5 speed there is also a Torsen diff in the rear which distributes torque side to side across the rear axle. In every case of quattro (even quattro-I) the front differential is open meaning more power is sent to the wheel that slips. The reason for this is that a limited slip device on the front axle would have a negative effect on A)tire wear and B)handling.

What Tabula may be referring to is the current quattro-IV system which uses EDL - a form of traction control that limits the torque sent to each wheel utilizing the ABS brakes to actually brake the axle. This does not increase traction or distribute torque - it merely limits slip. In no system of quattro yet developed does the torsen diff distribute torque to each wheel.

Under normal conditions, Haldex is probably around 90% front, 10% rear. Under SLIP conditions it locks up and it is quite quick - for a part-time AWD system. Compare to Syncro or Subaru's Viscous Coupling systems....where they rely on a viscous fluid to lock two clutch plates together - under some conditions it may take a half revolution of the wheels before it locks up...20 degrees is pretty darn quick...but not as quick as Torsen (or quattro-I) which are purely mechanical and have virtually no reaction time.

It is a case of reactive AWD (Haldex) vs proactive AWD (quattro)

sam fakt, że audi r8 wykorzystuje haldex tylko w ciut innej formie, Gallardo ma czy nawet Veyron

to chyba o czymś świadczy

lub to że audi w wyściagach korzysta z haldexa nie torsena

obecna generacja haldex w wielu aspektach prześcignęła już torsena i nie bądzcie krótkowzroczni, nie porównujcie torsena do pierwszych haldexów, które załaczały sie niewiadomo kiedy, elektornika teraz steruje wszystkim i rozwija się szybko co powoduje to że haldex jest wciąż ulepszany, a torsen to po prostu napęd mechaniczny klepany (chyba) od 74r. który tylko troche ewoluował od tego czasu

nawet Evo czy GT-Rowi blizej do haldexa niż torsena

tyle
