Abstract
A double clutch which has two friction clutches, a central pressure-exerting plate and two pressure plates that are axially movable relative to the pressure-exerting plate with the interposition of friction linings of two clutch disks, which mesh with each transmission input shaft, of actuating devices. Here, the pressure plates are acted on by transmission elements by the actuating devices directly without a lever action. Furthermore, for cooling and lubrication of actuating devices and transmission elements, an annular chamber with an increase in fluid volume can be formed.
