A force introduction fitting for lightweight components comprises two radial force introduction faces, at least one axial force introduction face and at least one receiving means for mounting and force introduction of the force introduction fitting. The radial force introduction face and the axial force introduction face enclose a cavity. The radial force introduction face and the axial force introduction face form a one-piece component. A wall is located between the radial force introduction faces and the axial force introduction face, and extends non-parallel to the axial force introduction face, at least in portions, and comprises a bearing face for fitting a retaining face of an anchor part. A force introduction fitting of this type can be produced by using a selective laser melting method. The force introduction fitting can thus be adapted flexibly to loading conditions and has advantageous material properties and a low weight.

1. A force introduction fitting for lightweight components, the force introduction fitting comprising: two disc-shaped radial force introduction plates;an axial force introduction surface in a form of a cylinder jacket having a first end and a second end, with one of the two disc-shaped radial force introduction plates connected to the first end and the other of the two disc-shaped radial force introduction plates connected to the second end, the second end being opposite to the first end;an anchor part; andat least one receiving means for mounting the anchor part,wherein the radial force introduction plates and the axial force introduction surface enclose a cavity, andwherein the force introduction fitting is formed as a one-piece component without joints, and the at least one receiving means is formed as a wall between and attached to at least one of the radial force introduction plates and is enclosed by the axial force introduction surface, extends non-parallel to the axial force introduction surface, at least in portions, and comprises a bearing face for fitting a retaining face of the anchor part,wherein the anchor part extends through an opening in one of the two disc-shaped radial force introduction plates to the outside. 2. The force introduction fitting according to claim 1, further comprising an opening defined in one of the radial force introduction plates, which opening is accessible from outside and extends from outside of the force introduction fitting into the cavity of the force introduction fitting. 3. The force introduction fitting according to claim 2, wherein at least one of the radial force introduction plates comprises a cut-out which opens into the opening in the one of the radial force introduction plates and extends radially outwards from a side of the receiving means opposite the side on which the bearing face is located. 4. The force introduction fitting according to claim 1, wherein the anchor part comprises a bell-shaped end, on the outer surface of which the retaining face is formed. 5. The force introduction fitting according to claim 1, wherein the wall of the receiving means comprises a slit. 6. The force introduction fitting according to claim 5, wherein the slit opens into the opening. 7. The force introduction fitting according to claim 1, wherein the bearing face is curved and a tangential gradient at the bearing face changes constantly from a root region of the wall to an opposite end of the wall. 8. The force introduction fitting according to claim 1, wherein the bearing face is a segment of a spherical surface. 9. The force introduction fitting according to claim 1, wherein a root region of the wall is connected to at least one of the radial force introduction plates. 10. The force introduction fitting according to claim 1, further comprising a counter face which is spaced apart from the wall of the receiving means in a radial direction parallel to at least one of the radial force introduction plates and is turned towards the bearing face. 11. The force introduction fitting according to claim 10, wherein the counter face is inclined relative to the at least one axial force introduction face, at least in portions. 12. The force introduction fitting according to claim 1, wherein the force introduction fitting is produced by a generative layer construction. 13. A lightweight component, comprising: at least one core layer;at least one facing; andat least one force introduction fitting including two disc-shaped radial force introduction plates, an axial force introduction surface in a form of a cylindrical jackets having a first end and a second end, with one of the two disc-shaped radial force introduction plates connected to the first end and the other of the two disc-shaped radial force introduction plates connected to the second end, the second end being opposite to the first end; an anchor part; and at least one receiving means for mounting the anchor part; wherein the radial force introduction plates and the axial force introduction surface enclose a cavity, wherein the force introduction fitting is formed as a one-piece component without joints, with the at least one receiving means formed as a wall between and attached to at least one of the radial force introduction plates and is enclosed by the axial force introduction surface, the at least one receiving means extending non-parallel to the axial force introduction surface, at least in portions, and including a bearing face for fitting a retaining face of the anchor part, and wherein the anchor part extends through an opening in one of the two disc-shaped radial force introduction plates to the outside; wherein the lightweight component comprises a receiving face, formed in accordance with the at least one axial force introduction face, for fitting against the axial force introduction surface of the force introduction fitting, andwherein an extension of the force introduction fitting is configured for flush coverage of the core layer and of the force introduction fitting fitted against the core layer. 14. The lightweight component according to claim 13, wherein the lightweight component is a fixture in an aircraft. 15. An aircraft, comprising: at least one built-in entity, which includes at least one lightweight component comprising at least one force introduction fitting for mounting the lightweight component, the force introduction fitting and including:two disc-shaped radial force introduction plates;an axial force introduction surface in a form of a cylinder jacket having a first end and a second end, with one of the two disc-shaped radial force introduction plates connected to the first end and the other of the two disc-shaped radial force introduction plates connected to the second end, the second end being opposite to the first end; an anchor part; and at least one receiving means for mounting the anchor part,wherein the radial force introduction plates and the axial force introduction surface enclose a cavity,wherein the force introduction fitting is formed as a one-piece component without joints, and the at least one receiving means is formed as a wall between and attached to at least one of the radial force introduction faces and is enclosed by the axial force introduction surface, extends non-parallel to the axial force introduction surface, at least in portions, and comprises a bearing face for fitting a retaining face of the anchor part, andwherein the anchor part extends through an opening in one of the two disc-shaped radial force introduction plates to the outside. 16. The aircraft according to claim 15, further comprising an opening defined in one of the radial force introduction faces, which opening is accessible from outside and extends from outside of the force introduction fitting into the cavity of the force introduction fitting. 17. The aircraft according to claim 15, wherein the anchor part comprises a bell-shaped end, on the outer surface of which the retaining face is formed. 18.
