Wet clutch, in particular DCT clutch

Wet clutch, comprising:

• a stationary stator;
• a clutch housing having a drive can driven by an engine;
• a first hydraulically activated clutch including a first clutch pack driving an inner drum connected to an outer shaft, wherein the first clutch pack includes;
• a plurality of steel plates, and
• a plurality of friction plates being positioned between the steel plates and at least one first clutch piston acting on the first clutch pack wherein
• disc springs are positioned between the steel plates, the disc springs having an outer conical surface spaced from an inner conical surface;
• a second hydraulically activated clutch including a second clutch pack driving an outer drum connected to an inner shaft, wherein the second clutch pack includes:
• a plurality of steel plates, and
• a plurality of friction plates being positioned between the steel plates and at least one second clutch piston acting on the second clutch pack wherein
• disc springs are positioned between the steel plates, the disc springs having an outer conical surface spaced from an inner conical surface;
• a central hub connected to the clutch housing and having a web separating the juxtaposed first and second clutch packs;
• a first piston-cylinder unit including the first clutch piston being activated by a first hydraulic activation chamber positioned between a first cylinder and one side of the first clutch piston acting on the first clutch pack;
• a second piston-cylinder unit including the second clutch piston being activated by a second hydraulic activation chamber positioned between a second cylinder and one side of the second clutch piston acting on the second clutch pack;
• balancing means including:
• a first balancing chamber positioned on the other side of the first clutch piston;
• and
• a second balancing chamber positioned on the other side of the second clutch piston;
• wherein the first and the second balancing chambers are fluidly connected to each other by distribution holes in the central hub to form a common balancing room and to connect to a common balancing oil passage in the stator;
• and
• wherein sealing rings are positioned between the stator and the piston cylinder units radially inside the piston-cylinder units at the smallest possible diameter thereof.
