explain DCT
two independant sub gearboxes (own clutch)
one odd other even gears
clutch for moving off and shifting
automated gear changing and clutch activation
explain maintasks masterclutch and dimensioning principles
transmission engine torque to gearbox
gentle and jerk-free moving off
damping torsion vibrations
minimal size and overload protection ICE and transmission
explain differences between masterclutch desings
Push
PKW
cheaper
simple fastening meechanism for release bearing simplifies assembly and disassembly
Pull
improved pressure and release force characteristics
higher pressure forces same space
lower releas forces
fewer parts, weigth, housing deflection losses
dry
efficency
small moment of interia
less complex, costs
wet
small space for installation
high power/weight ratio
large torque capacity
hiegh heat capacity
high durabilitiy at low wear
good contrallability
concentric
short space installation
parallel
small diameters
why dual fly wheels and how works
pro: damping torsional vibrations entire speed range
con: high costs higher moment of interia, installation space
seperated two plates
primary-> assigned to engine
secondary->transmission
connected by a grease-lubriced spring/damping-system
