Pull-Type Friction Clutch With Integrated Clutch Release Device

A friction clutch comprising:

• a clutch housing arrangement;
• a pressure plate coupled to the clutch housing arrangement so as to be fixed with respect to rotation relative to it and so as to be movable in direction of an axis of rotation;
• an integrated hydraulic clutch release device comprising a clutch release ring that is supported axially at the clutch housing by a first rolling bearing arrangement
• a spring arrangement configured to act on the pressure plate in a direction of clutch engagement,
• wherein, in order to disengage the friction clutch, the spring arrangement is pulled away from the pressure plate axially at its inner radial area by the clutch release ring, and
• wherein the clutch release device comprises a second rolling bearing arrangement arranged radially outside the clutch release ring and is axially displaceable with respect to the first rolling bearing arrangement,
• a sealed pressure fluid chamber into which pressure fluid can be admitted formed between the first and second rolling bearing arrangements, the pressure fluid chamber is defined on the radially outer side and radially inner side by the outer ring of the second rolling bearing arrangement which forms a ring piston.
