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

1 - 9 . (canceled)

10 . 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; and wherein the arrangement section on the axle tube side has an angle of enlacement of less than 180°.

11 . The longitudinal control arm of claim 10 , 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.

12 . The longitudinal control arm of claim 11 , 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.

13 . The longitudinal control arm of claim 12 , 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.

14 . The longitudinal control arm of claim 13 , 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 in a form-fitting and/or force-fitting manner connected to a 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.

15 . The longitudinal control arm of claim 14 , 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.

16 . The longitudinal control arm of claim 15 , 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.

17 . The longitudinal control arm of claim 16 , 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.

18 . The longitudinal control arm of claim 10 , 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.

19 . The longitudinal control arm of claim 10 , 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.

20 . The longitudinal control arm of claim 10 , 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 in a form-fitting and/or force-fitting manner connected to a 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.

21 . The longitudinal control arm of claim 10 , 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.

22 . The longitudinal control arm of claim 21 , 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.

23 . The longitudinal control arm of claim 21 , 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.

24 . A vehicle axle system, comprising a longitudinal control arm according to claim 10 .
