Design of the gearbox
Basic principle
In principle, the double-clutch gearbox consists of two
independent, gear train halves.
Gears 1, 3, 5 and 7 are shifted via clutch K1 and
therefore via gear train half 1 and output shaft 1.
In terms of function, each gear train half is designed
as a manual gearbox. A clutch is assigned to each
gear train half.
Gears 2, 4, 6 and reverse gear are conducted via
clutch K2 and therefore gear train half 2 and output
shafts 2 and 3.
The two clutches are dry clutches.
One gear train half is always positively connected.
The next gear can already be shifted in the other gear
train half, because the clutch for this gear is still open.
They are opened and closed and controlled by the
mechatronic unit depending on the gear which is to
be shifted.

A conventional, manual gearbox synchroniser and
shift unit is assigned to each gear.
