Abstract

The present invention relates to an exhaust-gas turbocharger for use in an internal combustion engine and to a method for assembling and/or setting an exhaust-gas turbocharger. According to the invention, the exhaust-gas turbocharger comprises a regulating mechanism and an actuator device for actuating the regulating mechanism, wherein the actuator device comprises a control rod with a first part and a second part. The second part of the control rod has a guide, which is designed in such a way that it at least partially surrounds the first part. Moreover, the second part has at least one hole, wherein the first part is connected to the second part by a welded or assembly joint, which is arranged in the at least one hole.

First claim

The invention claimed is:

1. An exhaust-gas turbocharger for use with an internal combustion engine, comprising:
a regulating mechanism; and
an actuator device for actuating the regulating mechanism, wherein the actuator device comprises a control rod with a first part and a second part,

wherein the second part has a guide, which is designed in such a way that it at least partially surrounds the first part,
wherein the second part comprises a first section and a second section, the first section and the second section being connected to each other by connection joints, which are located in an area around a connection and away from the guide such that there are no connection joints around the guide, and
wherein the second part has at least one hole, wherein the first part is connected to the second part by a welded or assembly joint, which is arranged in the at least one hole.

2. The exhaust-gas turbocharger as claimed in claim 1 , wherein the at least one hole is arranged in the region of the guide.

3. The exhaust-gas turbocharger as claimed in claim 1 , wherein the second part comprises at least two holes, and a welded or assembly joint is arranged in each of the holes, or a welded or assembly joint extends across all the holes, with the at least two holes optionally being arranged on an axis parallel to a longitudinal axis of the first part.

4. The exhaust-gas turbocharger as claimed in claim 1 , wherein the at least one hole is an elongate hole.

5. The exhaust-gas turbocharger as claimed in claim 4 , wherein a longitudinal axis of the elongate hole runs parallel to the longitudinal axis of the first part.

6. The exhaust-gas turbocharger as claimed in claim 1 , wherein the first section of the second part comprises a first portion of the at least one hole and the second section of the second part comprises a second portion of the at least one hole.

7. The exhaust-gas turbocharger as claimed in claim 6 , wherein the connection is arranged on the opposite side of the second part from the guide.

8. The exhaust-gas turbocharger as claimed in claim 5 , wherein the connection has a connection hole with a center line.

9. The exhaust-gas turbocharger as claimed in claim 8 , wherein the center of the hole or the centers of the holes lies/lie in a plane defined by the center line of the connection hole and the longitudinal axis of the first part.

10. The exhaust-gas turbocharger as claimed in claim 8 , wherein the center of the hole or the centers of the holes lies/lie in a plane which is perpendicular to the center line through the connection hole and which contains the longitudinal axis of the first part.

11. The exhaust-gas turbocharger as claimed in claim 1 , wherein the guide fixes the position of the first part relative to the second part, except for a degree of freedom parallel to the longitudinal axis of the first part.

12. The exhaust-gas turbocharger as claimed in claim 1 , wherein the first part is a metal sheet, a polygonal bar or a round bar.

13. The exhaust-gas turbocharger as claimed in claim 1 , wherein the guide is of sleeve-shaped design, with the sleeve-shaped guide optionally surrounding one region of the first part completely.

14. The exhaust-gas turbocharger as claimed in claim 1 , wherein the second part is produced from a stamping or a stamped and bent part.

15. An internal combustion engine, wherein the internal combustion engine comprises an exhaust-gas turbocharger as claimed in claim 1 .

16. A method for assembling and/or setting an exhaust-gas turbocharger as claimed in claim 1 , comprising:
attaching an actuating device to the exhaust-gas turbocharger, the actuating device comprising a control rod with a first part and a second part,
wherein the second part has a guide, which is designed in such a way that it at least partially surrounds the first part, and
wherein the second part comprises a first section and a second section, the first section and the second section being connected to each other by connection joints, which are located in an area around a connection and away from the guide such that there are no connection joints around the guide;

actuating the actuating device in such a way that the first part connected to the actuating means is moved into an appropriate working position;
arranging the second part in a predetermined position relative to the first part by longitudinal movement of the first and second parts relative to one another, using the guide of the second part, with the predetermined position being determined by the working position of the first part; and
attaching the second part to the first part in the predetermined position by means of the welded or assembly joint.
