Abstract

The present invention relates to a spring link for a motor vehicle, wherein the spring link is produced as an elongated, deformed hollow profile of open cross section made of a steel material and has respective attachment points at its ends, said spring link being characterized in that the spring link, in the installed position, is arranged with its opening of the hollow profile pointing upward, wherein a spring seat plate for receiving a helical compression spring is coupled to the spring link on and/or partially in the opening.

First claim

The invention claimed is:

1. Spring link for a motor vehicle, wherein
the spring link is produced as an elongated, deformed hollow profile of open cross section made of a steel material and has respective attachment points at longitudinal ends of the spring link,
the spring link, in an installed position, is arranged with an opening of the hollow profile pointing upward,
a spring seat plate for receiving a helical compression spring is coupled to the spring link on and/or partially in the opening,
the hollow profile, in the open cross section and the installed position, comprises:
a web,
two opposing legs extending upwardly from the web, and
in a region of the spring seat plate,
flanges protruding laterally from the legs, and
collars formed on the flanges, and

in the installed position and in the region of the spring seat plate,
the flanges protrude laterally from upper ends of the legs, and
the collars are bent downward from distal ends of the flanges toward the web.

2. Spring link according to claim 1 , wherein the hollow profile is of U-shaped or C-shaped or hat-shaped configuration in cross section.

3. Spring link according to claim 1 , wherein a spacing between the legs in the region of the spring seat plate is smaller than or equal to 1.2 times a spacing between the legs in a region of one of the longitudinal ends or attachment points.

4. Spring link according to claim 1 , wherein a spacing between the legs in the region of the spring seat plate corresponds to 0.5 times to 1.2 times a receiving diameter on the spring seat plate, the receiving diameter configured for receiving the helical compression spring.

5. Spring link according to claim 1 , wherein a spacing between the legs increases toward the opening and the legs extend at an angle in relation to one another.

6. Spring link according to claim 1 , wherein a spacing between the legs is reduced in a longitudinal direction of the spring link towards one of the longitudinal ends.

7. Spring link according to claim 1 , wherein
a straight connecting line through the attachment points forms a line of action, and
the hollow profile has an arched progression in relation to the line of action.

8. Spring link according to claim 7 , wherein, in the installed position, the arched progression is oriented below the line of action and/or the spring seat plate comprises a spring supporting surface lying below the line of action.

9. Spring link according to claim 1 , wherein
a wall thickness of the hollow profile is from 1.8 mm to 4.75 mm, and
a wall thickness of the spring seat plate is greater than or equal to the wall thickness of the hollow profile.

10. Spring link according to claim 1 , wherein a reinforcement plate is coupled in and/or on the opening of the hollow profile at least in a region of one of the longitudinal ends.

11. Spring link according to claim 1 , wherein the spring seat plate comprises:
a spring supporting surface, and
a bead oriented, in the installed position, upward with respect to the spring supporting surface to engage into the helical compression spring.

12. Spring link according to claim 1 , wherein a spacing between the legs in the region of the spring seat plate corresponds to 0.8 times to 1.1 times a receiving diameter on the spring seat plate, the receiving diameter configured for receiving the helical compression spring.

13. Spring link according to claim 1 , wherein
a straight connecting line through the attachment points forms a line of action,
the hollow profile is curved away from the line of action, and
in the installed position, the spring seat plate comprises a spring supporting surface lying below the line of action.

14. Spring link according to claim 13 , wherein the spring seat plate comprises a bead, which in the installed position is convex upward with respect to the spring supporting surface to engage into the helical compression spring.

15. Spring link for a motor vehicle, wherein
the spring link is produced as an elongated, deformed hollow profile of open cross section made of a steel material and has respective attachment points at longitudinal ends of the spring link,
the spring link, in an installed position, is arranged with an opening of the hollow profile pointing upward,
a spring seat plate for receiving a helical compression spring is coupled to the spring link on and/or partially in the opening,
the hollow profile, in the open cross section and the installed position, comprises:
a web,
two opposing legs extending upwardly from the web, and
in a region of the spring seat plate,
flanges protruding laterally from the legs, and
collars formed on the flanges, and

a spacing between the legs in the region of the spring seat plate is smaller than or equal to a spacing between the legs in a region of one of the longitudinal ends or attachment points.

16. Spring link for a motor vehicle, wherein
the spring link is produced as an elongated, deformed hollow profile of open cross section made of a steel material and has respective attachment points at longitudinal ends of the spring link,
the spring link, in an installed position, is arranged with an opening of the hollow profile pointing upward,
a spring seat plate for receiving a helical compression spring is coupled to the spring link on and/or partially in the opening,
the hollow profile, in the open cross section and the installed position, comprises:
a web,
two opposing legs extending upwardly from the web, and
in a region of the spring seat plate, collars formed on the legs, and

in the installed position and in the region of the spring seat plate, the collars are bent downward toward the web.
