Title: how does dsg gearboxes work?
Post by: dub_addicted on 12 May 2005, 22:08

Like this:

(Taken from the VW website...)

'Volkswagen GroupÂ’s Direct Shift Gearbox (DSG) combines the ease of an automatic car with the efficiency and flexibility of a manual.

While a conventional gearbox works with one clutch, the DSG transmission has two – one in gear, while the second has the next gear preselected.  When the gears need to shift, the second clutch takes the load, while the first preselects the next gear.  The whole process takes no more than three to four hundredths of a second – faster than the blink of an eye!

DSG transmissions also have a ‘tiptronicÂ’ function, allowing gears to be manually selected.  Tiptronic changes have a more ‘sportyÂ’ feel.

There are several benefits of the system.  These include improved acceleration and refined uninterrupted driving.  DSG is the first of its kind to feature in a production car, demonstrating Volkswagen GroupÂ’s ongoing commitment to developing remarkable technology.'

Apparently tho u (dont quote me on this cos ive never driven one; just read reports etc) cant fool it. That is if it thinks ur gonna change up but u change down it dont matter, it does it without fuss or drama.  Remains to be seen. Like ive said ive not driven one...yet!.....Might pop in and have a test drive......

Hope that helps!!

all gearboxes like this are annoying as hell. they won't let you select certain gears unless all the criteria are met. if you're on the gas and you dab the brakes it'll loose power. If you launch with you foot on the brake before you plant the gas you'll sit there until the car decides to go. even when in triptronic mode it still won't do what you want.

all these computers are no good. bring back drive by cable :D
