Abstract

Spring pack for a clutch arrangement of a motor vehicle drivetrain. The spring pack has a first ring element, has a second ring element and has a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs. The first and the second ring elements each have an inner circumferential section and an outer circumferential section. At least one of the first and the second ring elements has, in the region of at least one of its inner circumferential section and its outer circumferential section, a multiplicity of radially deformable elements which are designed so as to enable the spring pack to be centered in relation to a ring surface or so as to enable the spring pack to be mounted captively on the ring surface.

Claims (19)

1. A spring pack for a clutch arrangement of a motor vehicle drivetrain, having a first ring element, having a second ring element and having a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs, wherein the first and the second ring elements each have an inner circumferential section and an outer circumferential section;

wherein at least one of the first and the second ring element has, in a region of at least one of its inner circumferential section and its outer circumferential section, a multiplicity of radially deformable elements which are designed so as to enable the spring pack to be centered in relation to a ring surface; and

wherein the first and second ring elements are formed as identical parts.

2. The spring pack according to claim 1 , wherein at least one of the first and the second ring elements is in the form of a sheet-metal part with a circular inner circumferential section and an outer circumferential section, wherein the deformable elements are in the form of projections which protrude in relation to at least one of the circular inner circumferential section and the outer circumferential section.

3. The spring pack according to claim 2 , wherein the projections are oriented at an angle with respect to a radial plane of the sheet-metal part, wherein the angle is greater than 0 degrees and less than 90 degrees.

4. The spring pack according to claim 1 , wherein the deformable elements are formed integrally with the ring element.

5. A clutch arrangement for a motor vehicle drivetrain, having a carrier element which has an axially extending ring surface on which a spring pack is mounted, the spring pack having a first ring element, having a second ring element and having a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs, wherein the first and the second ring elements each have an inner circumferential section and an outer circumferential section, wherein at least one of the first and the second ring elements has, in a region of at least one of its inner circumferential section and its outer circumferential section, a multiplicity of radially deformable elements which have deformed on the ring surface and center the spring pack in relation to the carrier element, and wherein the first and second ring elements are formed as identical parts.

6. The clutch arrangement according to claim 5 , wherein another ring element is mounted in radially movable fashion.

7. A spring pack for a clutch arrangement of a motor vehicle drivetrain, having a first ring element, having a second ring element and having a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs, wherein the first and the second ring elements each have an inner circumferential section and an outer circumferential section;

wherein at least one of the first and the second ring elements has, in a region of at least one of its inner circumferential section and its outer circumferential section, a multiplicity of radially deformable elements which are designed so as to enable the spring pack to be mounted captively on a ring surface; and

wherein the first and second ring elements are formed as identical parts.

8. The spring pack according to claim 7 , wherein at least one of the first and the second ring elements are in the form of a sheet-metal part with a circular inner circumferential section and an outer circumferential section, wherein the deformable elements are in the form of projections which protrude in relation to at least one of the circular inner circumferential section and the outer circumferential section.

9. The spring pack according to claim 8 , wherein the projections are oriented at an angle with respect to a radial plane of the sheet-metal part, wherein the angle is greater than 0 degrees and less than 90 degrees.

10. The spring pack according to claim 7 , wherein the deformable elements are formed integrally with the ring element.

11. A clutch arrangement for a motor vehicle drivetrain, having a carrier element which has an axially extending ring surface on which a spring pack is mounted, the spring pack having a first ring element, having a second ring element and having a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs, wherein the first and the second ring elements each have an inner circumferential section and an outer circumferential section, wherein the at least one of the first and the second ring elements has, in a region of at least one of its inner circumferential section and its outer circumferential section, a multiplicity of radially deformable elements which have deformed on the ring surface and captively hold the spring pack in relation to the carrier element, and wherein the first and second ring elements are formed as identical parts.

12. The clutch arrangement according to claim 11 , wherein another ring element is mounted in radially movable fashion.

13. A method for producing a clutch arrangement, having the steps:

providing a spring pack having a first ring element, a second ring element, and a multiplicity of individual springs which are coupled to the first and the second ring elements such that the first and the second ring elements are movable relative to one another in an axial direction in a manner coupled by the springs, wherein the first and second ring elements are formed as identical parts; and

pushing the spring pack axially onto a carrier element of the clutch arrangement, wherein deformable elements of a ring element of the spring pack deform radially on the carrier element in order to at least one of center and captively hold the spring pack in relation to the carrier element.
