Direct-shift transmission 2
kfz-tech.de/PKp4
We want to take a closer look at the internal structure of a dual-clutch transmission. In principle, it doesn't matter whether it's dry or wet. The latter has several clutch plates, while the former has only
one.
Now, one might think that, as in the past, a sort of clutch mandrel is inserted into the central bearing, usually that of the crankshaft, in order to center the discs. Of course, this would have to be
a stepped clutch mandrel, since there are two different gear tooth diameters.
You see, you can forget about those particular considerations, because with the dual-clutch system, all rotating parts on the shaft are supported by roller bearings, or, more commonly, ball bearings.
This means that, as before, the flywheel is mounted on the crankshaft, and the complete dual-clutch assembly - consisting of two clutch discs and their respective friction partners - is mounted on
the transmission shaft.
Using appropriate drive components, torque is transmitted only to the respective friction partner on the motor side. Conclusion: In principle, this clutch is easier to install than a traditional one. There is
also no integrated adjustment mechanism like the one found on the SAC clutch. However, with certain manufacturers, it may be necessary to underlay the discs in such a way as to ensure a very
specific lever position of the release mechanism.
Of course, in the end, you'll have to use the computer again to force the actuator mechanism to go through a new programming process.
