A dual clutch transmission having radially nested clutches including an outer clutch having first inner and outer clutch disks that are interleaved between each other where the first outer clutch disks are operatively mounted to a first outer support carrier. The transmission also includes an inner clutch having second inner and outer clutch disks operatively interleaved between each other and operatively mounted to a second inner support carrier. A common disk carrier has a common clutch disk carrier that operatively supports the first inner clutch disks of the outer clutch and the second outer clutch disks of the inner clutch.

We claim: 1. A dual clutch transmission having radially nested clutches comprising: an outer clutch having a plurality of first outer clutch disks, a plurality of first inner clutch disks, and a first outer support carrier, said first inner clutch disks and said first outer clutch disks operatively interleaved between each other, said first outer clutch disks operatively mounted to said first outer support carrier; an inner clutch having a plurality of second outer clutch disks, a plurality of second inner clutch disks, and a second inner support carrier, said second inner clutch disks and said second outer clutch disks operatively interleaved between each other, said second inner clutch disks operatively mounted to said second inner support carrier; a common disk carrier having a common clutch disk carrier that operatively supports said first inner clutch disks of said outer clutch and said second outer clutch disks of said inner clutch; and a first actuating piston adapted to cause said first inner clutch disks and said first outer clutch disks of said outer clutch to operatively engage each other, wherein said first actuating piston and said common disk carrier form a compensation chamber that is adapted to be pressurized to compensate for excess outer clutch actuation pressure. 2. A dual clutch transmission as set forth in claim 1 that further includes a second actuating piston adapted to cause said second inner and said second outer disks of said inner clutch to operatively engage each other. 3. A dual clutch transmission as set forth in claim 2 that further includes a guide cylinder wherein said first actuating piston is disposed between said guide cylinder and said common disk carrier such that said guide cylinder and said first actuating piston form a pressure chamber that is adapted to be pressurized to cause said first actuating piston to actuate said outer clutch. 4. A dual clutch transmission as set forth in claim 2 that further includes a compensating piston wherein said second actuating piston is disposed between said compensating piston and said common disk carrier such that said common disk carrier and said second actuating piston form a pressure chamber that is adapted to be pressurized to cause said second actuating piston to actuate said inner clutch, and said second actuating piston and said compensating piston form a compensation chamber that is adapted to be pressurized to compensate for excess inner clutch actuation pressure. 5. A dual clutch transmission as set forth in claim 1 wherein said first actuating piston includes a plurality of circumferentially extending tabs and said common disk carrier includes a like plurality of corresponding openings such that said extending tabs extend though said openings to operatively engage said outer clutch assembly.
