Abstract

The invention relates to a longitudinal control arm for connection of an axle tube to a vehicle frame, the longitudinal control arm extending along a longitudinal direction and comprising an arrangement section on a frame side and at least one arrangement section on an axle tube side, a centerline of the arrangement section on the axle tube side being offset by an offset from a centerline of the arrangement section on the frame side when seen at an angle to the longitudinal direction.

First claim

The invention claimed is:

1. A longitudinal control arm for connection of an axle tube to a vehicle frame, said longitudinal control arm extending along a longitudinal direction and comprising:
an arrangement section on a frame side; and
at least one arrangement section on an axle tube side;
wherein a centerline of the arrangement section on the axle tube side is offset or displaced by an offset from a centerline of the arrangement section on the frame side when seen at an angle to the longitudinal direction;
wherein the longitudinal control arm comprises a box section with a hollow profile at least in regions;
wherein the longitudinal control arm has an upper support part and a lower support part;
wherein the lower support part includes a bearing surface configured to support a damper element;
wherein at least one of the upper support part and the lower support part include the arrangement section on the axle tube side; and
wherein the arrangement section on the axle tube side has an angle of enlacement of less than 180°; and
wherein the upper support part and the lower support part form a parting plane, which is positioned at an angle relative to the horizontal plane.

2. The longitudinal control arm of claim 1 , wherein the hollow profile preferably has a cross-section, which increases at least in regions in the direction of the arrangement section on the frame side.

3. The longitudinal control arm of claim 2 , wherein the longitudinal control arm has a curvature transverse to a horizontal plane, and wherein the curvature preferably extends between the arrangement section on the axle tube side and the arrangement section on the frame side.

4. The longitudinal control arm of claim 3 , wherein the upper support part and the lower support part form a parting plane, which is positioned at an angle relative to the horizontal plane.

5. A longitudinal control arm for connection of an axle tube to a vehicle frame, said longitudinal control arm extending along a longitudinal direction and comprising:
an arrangement section on a frame side; and
at least one arrangement section on an axle tube side;
wherein a centerline of the arrangement section on the axle tube side is offset or displaced by an offset from a centerline of the arrangement section on the frame side when seen at an angle to the longitudinal direction;
wherein the longitudinal control arm comprises a hollow profile at least in regions;
wherein the longitudinal control arm has an upper support part and a lower support part;
wherein at least one of the upper support part and the lower support part each has an arrangement section on the axle tube side;
wherein the arrangement section on the axle tube side has an angle of enlacement of less than 180°, and,
wherein at least one of the upper support part and the lower support part is connected to an adapter plate in at least one of a form-fitting and a force-fitting manner, and wherein the adapter plate is connected to a bearing surface in a form-fitting manner, and wherein the bearing surface is adapted for the arrangement of a spring/damper element and is at least one of form-fit connected and force-fit connected to a bearing surface.

6. The longitudinal control arm of claim 5 , wherein, on the arrangement section on the axle tube side, for connecting at least one of the axle tube and a wrap, the longitudinal control arm has at least one projection extending substantially along the axle tube.

7. The longitudinal control arm of claim 6 , wherein the at least one projection connects the longitudinal control arm and the at least one of the axle tube and the wrap in an arc.

8. The longitudinal control arm of claim 7 , wherein the projection is arranged on either side of the arrangement section on the axle tube side, and wherein the two projections have different widths.

9. The longitudinal control arm of claim 1 , wherein the longitudinal control arm has a curvature transverse to a horizontal plane, and wherein the curvature preferably extends between the arrangement section on the axle tube side and the arrangement section on the frame side.

10. The longitudinal control arm of claim 1 , wherein, on the arrangement section on the axle tube side, for connecting at least one of the axle tube and a wrap, the longitudinal control arm has at least one projection extending substantially along the axle tube.

11. The longitudinal control arm of claim 10 , wherein the at least one projection connects the longitudinal control arm and the at least one of the axle tube and the wrap in an arc.

12. The longitudinal control arm of claim 10 , wherein the projection is arranged on either side of the arrangement section on the axle tube side, and wherein the two projections have different widths.

13. A vehicle axle system, comprising a longitudinal control arm according to claim 1 .

14. The longitudinal control arm of claim 1 , wherein the box section has a rectangular cross-sectional configuration.
