DSG® dual clutch gearbox
Function of the DSG® dual clutch gearbox
Description
The vehicle is equipped with a DSG® dual clutch gearbox.
The DSG® dual clutch gearbox is a gearbox which uses dual-clutch technology to change gear
automatically. It uses a dual clutch and two gear train halves to enable very fast gear changes with
no loss of torque. The DSG® dual clutch gearbox thus combines the performance and economy of a
manual gearbox with the comfort and convenience of a conventional automatic gearbox.
Function
Engine power is transferred to the drive shaft via the gearbox. In order to change gears, the power
transmission between the engine and the gearbox has to be interrupted. This is what the clutch is
for.
With the DSG® dual clutch system with its two gear train halves, the engine power is always
connected to one gear train half when driving. Before a gear shift, the next-higher or lower gear is
already preselected in the load-free second gear train half. The clutch on the non-driven gear is then
closed, and the other is opened at the same time. This makes very fast gear changes possible.
Thanks to its design, the DSG® dual clutch gearbox is more efficient than an automatic gearbox.
Whereas in an automatic gearbox the torque converter is constantly in use, in the DSG® dual clutch
