A dual clutch arrangement for a dual clutch transmission for motor vehicles, having a first and a second friction clutch which are each fluidically actuable. A first piston arrangement serves to actuate the first friction clutch and has a first piston, a first piston space and a first centrifugal force equalizing space. A second piston arrangement serves to actuate the second friction clutch and has a second piston, a second piston space and a second centrifugal force equalizing space. The piston spaces and the centrifugal force equalizing spaces are situated in each case on opposite sides of the associated piston and are connected by means of feed lines to a valve arrangement.
