Coupling assembly filled with fluid

摘要

The arrangement has a piston (62) and a coupler (120) provided in a cooling chamber (220), where an effective connection is made between a gear and a drive by a coupling device based on the position of the piston with respect to the coupler. A drive-sided pressure chamber (112) is bordered by a drive-side of the piston and a separation wall (110) attached to the piston, where the wall is effective between the pressure chamber and the cooling chamber. The wall is arranged opposite to the piston in an axially displaceable manner.
