Abstract

Methods and systems are provided for an actuator connected to a turbocharger via a connecting arrangement. In one example, a system may include a connection arrangement which yields above a threshold force. The yielding of the connection arrangement may allow the movement of the actuator in a predetermined direction.

First claim

The invention claimed is:

1. A motor vehicle, comprising:
a turbocharger and a turbocharger housing; and
an actuator attached to the turbocharger housing via a bracket, wherein the bracket or a fastener is configured to yield when a threshold force between the actuator and the turbocharger housing is exceeded and the yielding allowing movement of the actuator;
the fastener arranged at a first end of a passage opening of the bracket and a material thickness of the bracket reduces from the first end to a second end.

2. The motor vehicle of claim 1 , wherein the fastener connects the bracket to the actuator, and the fastener extends through the passage opening of the bracket.

3. The motor vehicle as claimed in claim 2 , wherein the bracket has two arm portions each with a passage opening for the fastener, wherein an actuating rod is guided between the arm portions.

4. The motor vehicle of claim 3 , wherein at least one of the passage openings has an elongate shape.

5. The motor vehicle of claim 4 , wherein at least one of the passage openings is open at an edge.

6. The motor vehicle of claim 5 , wherein the at least of the passage openings is shaped such that the fastener is held in a position and a portion of the at least one of the passage openings is configured to yield when the threshold force is exceeded to release the actuator.

7. The motor vehicle of claim 6 , wherein the portion of the at least one of the passage openings configured to yield comprises an inwardly directed protrusion.

8. The motor vehicle of claim 1 , wherein the fastener holds the actuator in a position, and yielding of the fastener releases the actuator from the position.

9. The motor vehicle of claim 1 , wherein a protrusion of the bracket holds the fastener in a position and the actuator in a position, and yielding of the protrusion releases the actuator from the position.

10. A motor vehicle, comprising:
a turbocharger and a turbocharger housing;
an actuator attached to the turbocharger housing via a bracket;
a fastener extending through a passage opening in the bracket;
the bracket or the fastener configured to yield when a threshold force between the actuator and the turbocharger housing is exceeded; and
the yielding of the bracket or fastener releases the actuator to move along a path defined by the passage opening.

11. The motor vehicle of claim 10 , wherein the passage opening is positioned in an arm of the bracket and the passage opening has an elongated shape and is open at a terminal end.

12. The motor vehicle of claim 11 , wherein a protrusion is positioned between the fastener and the terminal end.

13. The motor vehicle of claim 12 , wherein a material thickness of the protrusion is less than that of the arm of the bracket.

14. The motor vehicle of claim 10 , wherein a protrusion of the bracket holds the fastener in a position and the actuator in a position, and yielding of the protrusion releases the actuator from the position.

15. The motor vehicle of claim 14 , wherein the protrusion is located on an arm of the bracket, and
the protrusion has a lower material thickness than the arm of the bracket.

16. A vehicle, comprising:
a turbocharger and a turbocharger housing;
an actuator attached to the turbocharger housing via a bracket; and
a guide face of the bracket positioned between a motor and a passenger compartment, and the guide face configured to guide an actuator in a direction oblique to a longitudinal axis of the vehicle upon detachment of the actuator due to detachment or deformation of the bracket or a fastener when a threshold force is exceeded.

17. The vehicle of claim 16 , wherein the bracket detaches or deforms when the threshold force is exceeded to release the actuator.

18. The vehicle of claim 17 , wherein the guide face extends obliquely to the longitudinal axis and the guide face guides the detached actuator in the direction that the guide face extends.

19. The vehicle of claim 16 , wherein an arm extends from the guide face and the fastener is inserted through the arm, and
the fastener detaches or deforms when the threshold force is exceeded to release the actuator.

20. The vehicle of claim 16 , wherein a shape of a passage through the bracket holds the fastener in a position, and
the shape of the passage detaches or deforms when the threshold force is exceeded to release the actuator.
