Patent ID: 7648012

Claim:
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, wherein the friction clutches have in each case one input member, with the input members being mounted on a hub and with the hub being rotationally fixedly connected to a drive input shaft, and wherein the hub is mounted for rotation on an axially projecting hollow spigot section of a rotary leadthrough, the spigot section arranged concentrically around two output shafts, a first piston arrangement which 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 which serves to actuate the second friction clutch and has a second piston, a second piston space and a second centrifugal force equalizing space, with the piston spaces and the centrifugal force equalizing spaces being situated in each case on opposite sides of the associated piston and being connected by means of feed lines to a valve arrangement, wherein the centrifugal force equalizing spaces are connected to the valve arrangement by means of a common line, and wherein the rotary leadthrough has an annular duct which forms the common line to the two centrifugal force equalizing spaces.
