Tidy up discussion (gearbox types vs trade names)

Latest comment: 18 years ago1 comment1 person in discussion

This Dual-Clutch stub is very good (description). The term Dual-Clutch is a good generic term for what Volkswagen Group are calling DSG (and the manufacturer BorgWarner call DualTronic). Should the DSG and Dual-Clutch artcils be linked/merged or better matched to each?

My thinking is this:

  • The new Dual-Clutch article should carry the in-depth explanation.
  • The DSG article should detail the VW / BorgWarner usage in which models etc.

(I am very new to WikiPedia, so go easy on me!) Mark 23:00, 8 September 2005 (UTC)

I generally agree: link to DSG, but don't merge this w/ DSG -- or else it will be hard to separate again, as will eventually be necessary since Veyron, Koenigsegg, and some Porsche street-legalized 956/962's manufactured by Joest, Dauer, etc. already have diffeent DCT's than the DSG, and more automakers also have their own DCT's in the works. This article can carry a short description of (and link to) each brand-name of DCT, such as the DSG page. And as more DCT's spring up, if their proprietary technology is markedly different, it's best to just link to a page for each company's DCT for in-depth descriptions if and when people provide that for each company.

'Twin-clutch gearbox redirects to this page. How do I change the link in the box so that it will go directly to this page? —Gm1121983 9:37 20 April 2006

Okay, I moved the article to Twin-clutch Gearbox, and I moved the talk page accordingly. Does anyone know why the discussion tab is still in red print? —Gm1121983 17:28 20 April 2006

  • Well, why is it red!? —Gm1121983 18:44 20 April 2006

According to reference[1], the first dual clutch transmission was patented by Rudolph Franke, a Professor at The Darmstadt Technical University in 1940. It was applied and tested in a truck but never went into production.

The following line in Wikipedia article could be incorrect - 'This type of gearbox was invented by Andolphe Kégresse just before the outbreak of World War II, but he never developed a working model'.

twin clutch is not same as multi plate clutch

Latest comment: 16 years ago1 comment1 person in discussion

"Twin clutch" or "dual clutch" contains two clutches that can be connected to for exampel odd/even gears. Twin clutch is not the same as a "multi plate clutch" which is one clutch with multiple plates connected to one shaft. For eample the Koenigsegg CCX has a multi disc clutch, and not a twin clutch, and should therefore not be mentioned on this page even if it's multi plate clutch contains two discs.

Each of the two clutches in a twin clutch can contain multiple clutch discs as they do in for example the VW DSG.

Another form of twin clutch is the combination of transmission clutch and power take off clutch. —Preceding unsigned comment added by 87.248.10.91 (talk) 19:52, 3 November 2007 (UTC)

basic info missing

Latest comment: 16 years ago2 comments2 people in discussion

a regular clutch, is needed for 1st and R?...other shifts are manually commanded but carried out by computer? Since there are two neutrals, the computer does something similiar to double-clutching when shifting? CorvetteZ51 13:12, 24 March 2007 (UTC)

How much does this help acceleration? Especially on turbo charged engines it should be of great benefit that you don't have to let go of the throttle, right? —Preceding unsigned comment added by 83.227.28.208 (talk) 14:49, 24 May 2008 (UTC)

Porsche PDK

Latest comment: 16 years ago1 comment1 person in discussion

Today (June 6, 2008) Porsche announced that the new 911 will include the PDK. This is worth noting in the article. Reference: http://www.porsche.com/usa/aboutporsche/pressreleases/pcna/?lang=none&pool=international-de&id=2008-06-06-01 MisterRisky (talk) 15:36, 6 June 2008 (UTC)

dctfacts.com is not a reliable source

Latest comment: 14 years ago4 comments3 people in discussion

dctfacts.com, a site which is cited extensively in this article is not a reliable source. It is a blog-style collection of DCT information sponsored by a chemical company. If DCT references are to be given then they should come from trusted industry publications and news sources. What do others think? --Biker Biker (talk) 22:56, 30 October 2009 (UTC)

I stongly disagree. DTCfacts categorically IS a reliable source, and furthermore, all the given citations are totally and utterly verifiable by various 3rd party sources (so weather any individual has any 'difficulty' in accepting the citations as 'truth' is not a justification for not including them). DTCfacts is produced by the extremely highly regarded Lubrizol Corporation; Lubrizol is highly respected by virtually all worldwide automakers, and oil companies. Lubrizol is also completely independent from any of the automakers and oil companies (though naturally, it does carry out 'business' with them). Furthermore, Lubrizol is listed as a Fortune 1000 company - so hardly some upcoming new-shot company. Finally, DCTfacts clearly has articles from ALL users and suppliers of DCTs (whom also happen to use manual and conventional auto transmissions) - so they could not be described as having a bias either!
And you think that 'motorcycle-usa.com' and similar (no doubt a bunch of journalists without any kind of professional peer-reviewed qualifications) is more of a reliable source than DCTfacts? I would personally put my trust in professionally educated sources, rather than journos whos opinions can be skewed 'advertising revenues'. Kind regards. 78.32.143.113 (talk) 10:52, 31 October 2009 (UTC)
It looks quite professional but lack some info I cant find a word from Fiat clutch there, but oddly Renault is there when its going to release one year later... generally I think we should use wide variety of different sources and not use one as main source --Typ932 T·C 13:10, 31 October 2009 (UTC)
Typ932, I can't actually recall seeing the Fiat DCT on DCTfacts (so my bad in that example!) Anyway, I hope you agree that there are now a very wide range of differing sources cited on this subject. 78.32.143.113 (talk) 14:18, 31 October 2009 (UTC)

Cost and adoption

Latest comment: 13 years ago1 comment1 person in discussion

Anybody come across reliable sources that state a cost or price premium for DCTs? I am interested in how much more they cost and its effect on mass market industry adoption. Ng.j (talk) 16:59, 3 May 2011 (UTC)

Serious problems through out

Latest comment: 12 years ago1 comment1 person in discussion

I can't say I'm much a gear head, but I suspect the description section of this article is largely indecipherable even to an expert. The description of the system's operation is largely missing, and the reason for its use is entirely missing (i.e., its stated why it's better, but why is it ABLE to do that?). Consider, for instance, the statement about torque being applied to both at the same time -- well sure, but HOW?

Moreover the majority of the article consists largely of listcruft. This is subject to constant change and really shouldn't be here at all.

Maury Markowitz (talk) 14:23, 2 March 2012 (UTC)

Agreed. As someone who is very familiar with the operation of both manual and automatic transmissions I find this entire article to be thoroughly unhelpful in its description of the actual operation of dual clutch transmissions.

Assessment comment

The comment(s) below were originally left at Talk:Dual-clutch transmission/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

Hi

I think the 2 articles should remain separate in light of a number of companies now coming out with Dual Clutch Transmissions. DSG and S-Tronic are just VW Group's trade names for their version of a DCT. Aside from the fact they were first, as many other companies have either released a DCT or have one in development, the two topics should remain separate.

As a side note... I think the DCT article should be expanded to include up-to-date information on DCT's. Ford now have one coming out too with BMW said to be working on one as well.
