Claim:
1. A double clutch for coupling a drive shaft of a vehicle motor to a transmission shaft of a vehicle transmission and/or to an accessory power-take-off of the motor vehicle, in particular to a power take-off shaft, comprising: a first friction clutch for frictionally clamping a first clutch disc couplable to the transmission shaft between a first pressure plate and a first counter-plate, the first pressure plate displaceable in an axial direction to close the first friction clutch, wherein the first friction clutch is at least partially enclosed by a clutch cover; a second friction clutch for frictionally clamping a second clutch disc couplable to the accessory power take-off between a second pressure plate and a second counter-plate, the second pressure plate displaceable in the axial direction to close the second friction clutch; a first actuating element configured to displace the first pressure plate; and, a second actuating element configured to engage a pressure ring connected to the second pressure plate to displace the second pressure plate, wherein the pressure ring surrounds the first friction clutch essentially on the outside and at least partially passes through the clutch cover, the pressure ring having a cylindrical wall portion that directly abuts against the second pressure plate; wherein the second actuating element is pre-loaded by at least one wire load ring.
