Abstract

The present invention relates to an insert element ( 3 ) for transmitting a force for a camshaft adjustment system. The insert element ( 3 ) has a first region ( 1 ) with an end surface ( 4 ) for receiving the force, and a second region ( 2 ) for conducting away the force. The end surface ( 4 ) is arranged in such a manner that it has, by means of a locking element ( 7 ), at least one force transmission point for receiving the force. The second region ( 2 ) is arranged in such a manner that it has, by means of a stator element ( 6 ), a force transmission surface for conducting away the force.

Claims (52)

1. Insert element for transmitting a force for a camshaft adjustment system, the insert element comprising:

a first region located at an outer periphery of the insert element with an end surface for receiving the force;

a second region located at the outer periphery away from the first region for conducting away the force;

the end surface is arranged such that it has at least one force transmission point for receiving the force, at least one groove is arranged such that the groove divides the end surface into a plurality of partial end surfaces located at the outer periphery;

the force transmission point is arranged such that it can be coupled to a locking element;

the second region is arranged such that it has a force transmission surface for conducting away the force; and

the force transmission surface is arranged such that it can be coupled to a stator element.

2. Insert element according to claim 1 , wherein the end surface forms a flat surface.

3. Insert element according to claim 1 , wherein the end surface is of concave or convex design.

4. Insert element according to claim 1 , wherein the end surface is arranged such that it can be coupled to the locking element which has a tapering surface.

5. Insert element according to claim 1 , wherein the second region is arranged such that it can be fastened in a receiving region of the stator element.

6. Insert element according to claim 5 , wherein the second region can be fastened in the receiving region such that at least one degree of freedom can be provided between the second region and the stator element.

7. Locking arrangement for transmitting a force for a camshaft adjustment system, the locking arrangement comprising:

a locking element;

a stator element; and

an insert element having a first region located at an outer periphery of the insert element with an end surface for receiving the force, at least one groove is arranged such that the groove divides the end surface into a plurality of partial end surfaces located at the outer periphery;

a second region located at the outer periphery away from the first region for conducting away the force;

the end surface is arranged such that it has at least one force transmission point for receiving the force;

the force transmission point is arranged such that it can be coupled to the locking element;

the second region is arranged such that it has a force transmission surface for conducting away the force; and

the force transmission surface is arranged such that it can be coupled to the stator element.

8. Locking arrangement according to claim 7 , wherein the insert element can be mounted in the receiving region by a floating mounting.

9. Locking arrangement according to claim 8 , wherein the stator element has a groove for supplying a bearing liquid for the receiving region.

10. Locking arrangement according to claim 7 ,

wherein the locking element comprises a locking pin;

the locking pin has an end region;

the end region has a tapering surface; and

the end region and the end surface form the at least one force transmission point.

11. Method for transmitting a force in a camshaft adjustment system, wherein the method comprises:

receiving the force by a locking element by at least one force transmission point of an end surface of an insert element, the end surface including at least one groove arranged such that the groove divides the end surface into a plurality of partial end surfaces located at an outer periphery of the insert element; and

conducting the force out of the insert element into a stator element by a force transmission surface of the insert element.

12. Method according to claim 11 , wherein the insert element is fastened to a receiving region of the stator element; and

the insert element is fastened in such a manner that at least one degree of freedom is provided between the second region and the stator element.

13. Locking arrangement for transmitting a force for a camshaft adjustment system, the locking arrangement comprising:

a locking element;

a stator element; and

an insert element having a first region with an end surface for receiving the force, at least one groove is arranged such that the groove divides the end surface into a plurality of partial end surfaces;

a second region for conducting away the force;

the end surface is arranged such that it has at least one force transmission point for receiving the force;

the force transmission point is arranged such that it can be coupled to the locking element;

the second region is arranged such that it has a force transmission surface for conducting away the force;

the force transmission surface is arranged such that it can be coupled to the stator element; and

the locking element comprises a locking pin, and the end surface of the insert element for receiving the force is only located on one radial side of the locking pin.

14. Locking arrangement for transmitting a force for a camshaft adjustment system, the locking arrangement comprising:

a locking pin;

a stator element; and

an insert element having a first region with an end surface for receiving the force;

a second region for conducting away the force;

the end surface is arranged such that it has at least one force transmission point for receiving the force;

the force transmission point is arranged such that it can be coupled to the locking pin, and the end surface of the insert element for receiving the force is only located on one radial side of the locking pin;

the second region is arranged such that it has a force transmission surface for conducting away the force; and

the force transmission surface is arranged such that it can be coupled to the stator element.
