Manualni vs automatski mjenjači


Recommended Posts

Borg Warner je originalno razvio DSG, a prvi put je upotrebljen u Audiju TT :)

 

This type of transmission was invented by Frenchman Adolphe Kégresse just before World War II but he never developed a working model. The first development of the Twin Clutch or Dual-clutch transmission started in the early part of 1980 under the guidance of Harry Webster at Automotive Products (AP), Leamington Spa with prototypes built into the Ford Fiesta Mk1, Ford Ranger & Peugeot 205. Initially, the control systems were based on purely analogue/discrete digital circuitry with patents filed in July 1981.[4] All of these early AP Twin Clutch installations featured a single dry clutch and multi-plate wet clutch. Following discussions with VW/Porsche, DCT work continued from Porsche in-house development, for Audi and Porsche racing cars later in the 1980s,[2] when computers to control the transmission became compact enough: the Porsche Doppelkupplungsgetriebe (English: dual-clutch gearbox) (PDK)[2] used in the Porsche 956[2] and 962[2] Le Mans race cars from 1983,[2] and the Audi Sport Quattro S1 rally car.[5][6]

 

A dual-clutch transmission eliminates the torque converter as used in conventional epicyclic-geared automatic transmissions.[1] Instead, dual-clutch transmissions that are currently on the market primarily use two oil-bathed wet multi-plate clutches, similar to the clutches used in most motorcycles, though dry clutch versions are also available.[7]

 

The first series production road car with a DCT was the 2003 Volkswagen Golf Mk4 R32.[2][8][9]

Ja gledam taj tvoj video i ne znam kako ti po video mozes zakljuciti da DSG salta brze od IS-F? Ovo fakat brzo salta i ne vidim kako je to losije od DSGa. Cak mi se cini da je na IS-Fu malo agresivnije.

U voznji je meni S4 ostavio bolji dojam po pitanju saltanja, jednostavno u isfu ima zadrska od kako kliknes na volanu dok usalta, na audiju mi je to nekako trenutno bilo, oba su vrhunski, meni osobno je dojam da audi salta/reagira brze

 

Gonzo, to ti je lexus kvaliteta

Ma rijesili su I te lampice I jednako se vozio, bio mu je traction control crkao

komunikacija ti je na razini prvog srednje. :thumbsup: a i znanje izgleda jer uz sve cinenice koje su ovdje iznesene ti si i dalje u nekom svom filmu.

 

 

Prilagodio sam se tebi da bolje razumiješ :thumbsup:

 

A i ne znam tko je prvi počeo s urlikanjem na razini prvog srednje o superiornosti DSGa.
