Abstract
A dual clutch transmission for motor vehicles, with two subtransmissions, with a dual clutch, with a central disk () connected to the driving disk () and belonging to the dual clutch, with two outer pressure plates () and with friction disks () which are arranged between the central disk () and the pressure plates () and which can be coupled individually to the central disk () and transfer the torque selectively to the sub transmissions via one of the clutch output shafts (solid shaft, hollow shaft). Dual clutch transmissions often suffer from noise and vibration problems which mostly arise during crawling actions, when starting from a standstill, in load alternation processes and during gear changes. In order to avoid this, the central disk () is decoupled from the driving disk () and is mounted on the hollow shaft (); furthermore, the central disk () is connected cardanically to the driving disk ().
