A clutch arrangement includes a clutch device for transmitting torque between a clutch housing and a takeoff, wherein a pressure element and an opposing pressure element cooperate to establish and release a working connection between at least one drive-side clutch element and at least one takeoff side clutch element. The opposing pressure element is mounted nonrotatably and without freedom of axial movement on the clutch housing, and is connected to at least one drive-side clutch element by axially acting energy storage devices. A takeoff-side clutch element is located between a drive-side clutch element and the opposing pressure element, and between any adjacent drive-side clutch elements. Alternatively, the axially acting energy storage devices can connect the drive-side clutch elements to the clutch housing.

1. A clutch arrangement comprising a clutch housing, a takeoff, and a clutch device for transmitting torque between the clutch housing and the takeoff, the clutch device comprising: at least one drive-side clutch element;at least one takeoff-side clutch element;a pressure element;an opposing pressure element which cooperates functionally with the pressure element to establish and release a working connection between the at least one drive-side clutch element and the at least one takeoff side clutch element, wherein the opposing pressure element is mounted nonrotatably and without freedom of axial movement on the clutch housing; andaxially acting energy storage devices connecting the opposing pressure element and the at least one drive-side clutch element, said at least one takeoff-side clutch element being located between one of said at least one drive-side clutch element and said opposing pressure element, and between one of said at least one drive-side clutch element and any adjacent said drive-side clutch element. 2. The clutch arrangement of claim 1 wherein each of said axially acting energy storage devices has one end attached to one of said at least one drive-side clutch element and another end attached to one of the opposing pressure element and another said drive-side clutch element. 3. The clutch arrangement of claim 2 wherein each said at least one drive-side clutch element has a ring-shaped base body and a plurality of radially extending mounts to which respective said ends of said axially acting energy storage devices are fixed. 4. The clutch arrangement of claim 3 wherein the axially acting energy storage devices are leaf springs which extend substantially tangentially to the ring-shaped base body. 5. The clutch arrangement of claim 1 wherein the axially acting energy storage devices are pre-stressed to axially separate one of said at least one drive-side clutch element from said opposing pressure element, and to axially separate one of said at least one drive-side clutch element from any adjacent said drive-side clutch element. 6. The clutch arrangement of claim 1 wherein the axially acting energy storage devices are pre-stressed to axially draw one of said at least one drive-side clutch element toward said opposing pressure element, and to axially draw one of said at least one drive-side clutch element toward any adjacent said drive-side clutch element. 7. The clutch arrangement of claim 1 wherein the pressure element separates a first pressure space from a second pressure space, wherein positive pressure in the first pressure space relative to the second pressure space causes an axial displacement of the pressure element toward the clutch elements and toward the opposing pressure element, and the displacement of the clutch elements toward each other and toward the opposing pressure element. 8. The clutch arrangement of claim 1 wherein the pressure element separates a first pressure space from a second pressure space, wherein positive pressure in the second pressure space relative to the first pressure space causes an axial displacement of the pressure element away from the clutch elements and from the opposing pressure element, and the displacement of the clutch elements away from each other and from the opposing pressure element. 9. The clutch arrangement of claim 1 wherein the clutch housing comprises a housing cover and main housing part enclosing a hydrodynamic circuit, the opposing pressure element being located axially between the housing cover and main housing part. 10. The clutch arrangement of claim 9 wherein the opposing pressure element is connected to the housing cover and the main housing part by one of welding and laser welding. 11. The clutch arrangement of claim 1 further comprising a torsional vibration damper having an input part and an output part, the at least one take-off side clutch element being connected to the input part for rotation in common. 12. The clutch arrangement of claim 11 further comprising a hydrodynamic circuit formed by a pump wheel and a turbine wheel in the clutch housing, the input part being connected nonrotatably to the turbine wheel, the output part being connected nonrotatably to the takeoff. 13. The clutch arrangement of claim 1 further comprising a flow guide element between the pressure element and the clutch elements, at least one flow groove being formed axially between the flow guide element and the pressure element. 14. The clutch element of claim 13 wherein the pressure element acts on the clutch elements by way of the flow guide element. 15. A clutch arrangement comprising a clutch housing, a takeoff, and a clutch device for transmitting torque between the clutch housing and the takeoff, the clutch device comprising: at least one drive-side clutch element;at least one takeoff-side clutch element;a pressure element;an opposing pressure element which cooperates functionally with the pressure element to establish and release a working connection between the at least one drive-side clutch element and the at least one takeoff side clutch element,axially acting energy storage devices connecting the clutch housing and the at least one drive-side clutch element for rotation in common, the at least one said takeoff-side clutch element being located between one of said at least one drive-side clutch element and said clutch housing, and between one of said at least one drive-side clutch element and any adjacent said at least one drive-side clutch element,wherein each of said axially-acting energy storage devices has one end attached to one of said at least one drive-side clutch element and another end attached to one of the clutch housing and another said drive-side clutch element, andwherein each said at least one drive-side clutch element has a ring-shaped base body and a plurality of radially extending mounts to which respective said ends of said axially-acting energy storage devices are fixed. 16. The clutch arrangement of claim 15 wherein the axially acting energy storage devices are leaf springs which extend substantially tangentially to the ring-shaped base body. 17. The clutch arrangement of claim 15 wherein the axially acting energy storage devices are pre-stressed to axially separate one of said at least one drive-side clutch element from said clutch housing, and to separate one of said at least one drive-side clutch element from any adjacent said at least one drive-side clutch element. 18. The clutch arrangement of claim 15 wherein the axially acting energy storage devices are pre-stressed to axially draw one of said at least one drive-side clutch element toward said clutch housing, and to draw one of said at least one drive-side clutch element toward any adjacent said at least one drive-side clutch element.
