Abstract

A method for producing a plug connector and to a plug connector for rotationally connecting a first component to a second component, for example, in a clutch assembly, where the first component includes at least one connecting element, where the connecting element protrudes through an opening of the second component, where the connecting element has an end piece above the second component, where a cross-section of the end piece is wider than a cross-section of the opening, where the widening of the end piece is produced by means of a rolling method.

First claim

What is claimed is:

1. A mating connection for a clutch assembly, comprising:
a first component including:
an annular disc;
at least one flange along an outer border of the annular disc;
a sleeve extending from the annular disc in a first direction;
a first opening surrounded by the annular disc and the sleeve; and,
a first plurality of teeth extending from the sleeve in the first direction; and,

a second component including:
an annular surface;
a plurality of openings in the annular surface, wherein:

none of the openings in the plurality of openings is open to the first opening;
each tooth included in the plurality of teeth extends through a respective opening included in the plurality of openings;
said each tooth has a respective end piece extending beyond the second component in the first direction; and,
the respective end piece extends beyond the respective hole in a second direction from the respective hole toward the first opening.

2. The mating connection as recited in claim 1 , wherein the plurality of openings is open in a lateral direction.

3. The mating connection as recited in claim 1 , wherein the second component is a ring gear.

4. The mating connection as recited in claim 3 , wherein the ring gear has an angled cross-section with a first surface portion of the ring gear extending essentially in parallel with an upper side of the first component, the plurality of openings being formed in the first surface portion, and wherein the a second surface portion is angled in the direction of the first component, a tooth structure of the ring gear being formed on the second surface portion.

5. The mating connection as recited in claim 4 , wherein the second surface portion is formed on an interior side of the ring gear with the tooth structure protruding in an inward direction or wherein the second surface portion is formed on an exterior side of the ring gear with the tooth structure protruding in an outward direction.

6. A method for creating the mating connection as recited in claim 1 , wherein the components are combined by passing the first plurality of teeth of the first component through the plurality of openings of the second component, comprising the step of rolling a roller across the respective end pieces of the first plurality of teeth to exert pressure on the respective end pieces at least partly in a lateral direction to achieve a widening of the respective end pieces.

7. The method as recited in claim 6 , wherein the roller is rolled across the respective end pieces of the first plurality of teeth essentially along a longitudinal side of the first plurality of teeth.

8. The method as recited in claim 6 , wherein the first and second components are caused to rotate and the rotating first plurality of teeth is moved across the roller that is supported for rotation.

9. The method as recited in claim 8 , wherein the first plurality of teeth is moved in the direction of the roller during the rotation.

10. The method as recited in claim 6 , wherein a relative direction of movement between the roller and the first and second components is changed at least once.

11. The method as recited in claim 6 , wherein an axis of rotation of the roller is arranged to be inclined relative to a central axis of rotation of the first and second components in a radial direction by an angle in the direction of the first and second components.

12. A mating connection for a clutch assembly, comprising:
a first component including:
an annular disc;
at least one flange along an outer border of the annular disc;
a sleeve extending from the annular disc in a first direction;
a first opening surrounded by the annular disc and the sleeve; and,
a plurality of teeth extending from the sleeve a first distance in the first direction; and,
a plurality of segments, each segment in the plurality of segments:
formed between respective first and second teeth included in the plurality of teeth; and,
extending from the sleeve a second distance less than the first distance; and,

a second component including:
an annular portion;
a plurality of openings in the annular portion, wherein:

each tooth included in the plurality of teeth extends through a respective opening included in the plurality of openings;
said each tooth has a respective end piece extending beyond the second component in the first direction; and,
the respective end piece overlaps the annular portion between the respective opening and the first opening.

13. The mating connection as recited in claim 12 , wherein the plurality of openings is open in a lateral direction.

14. The mating connection as recited in claim 12 , wherein the second component is a ring gear.

15. The mating connection as recited in claim 14 , wherein the ring gear has an angled cross-section with a first surface portion of the ring gear extending essentially in parallel with an upper side of the first component, the plurality of openings being formed in the first surface portion, and wherein the a second surface portion is angled in the direction of the first component, a tooth structure of the ring gear being formed on the second surface portion.

16. The mating connection as recited in claim 15 , wherein the second surface portion is formed on an interior side of the ring gear with the tooth structure protruding in an inward direction or wherein the second surface portion is formed on an exterior side of the ring gear with the tooth structure protruding in an outward direction.

17. A method for creating the mating connection as recited in claim 12 , wherein the components are combined by passing the first plurality of teeth of the first component through the plurality of openings of the second component, comprising the step of rolling a roller across the respective end pieces of the first plurality of teeth to exert pressure on the respective end pieces at least partly in a lateral direction to achieve a widening of the respective end pieces.

18. The method as recited in claim 17 , wherein the roller is rolled across the respective end pieces of the first plurality of teeth essentially along a longitudinal side of the first plurality of teeth.

19. The method as recited in claim 17 , wherein the first and second components are caused to rotate and the rotating first plurality of teeth is moved across the roller that is supported for rotation.

20. The method as recited in claim 19 , wherein the first plurality of teeth is moved in the direction of the roller during the rotation.
