Abstract

A cross-member is provided for a vehicle having a frame structure including two longitudinal beams, wherein the cross-member includes a main portion and two end-sections wherein each end section includes an outer surface for facing an inner surface of a longitudinal frame beam wherein the cross-member includes at least one protrusion extending from the outer surface of the end-sections for being introduced into a hole or notch of the frame beam for forming a form-lock to one more components to be mounted to the longitudinal frame beam.

First claim

The invention claimed is:

1. A cross-member for a vehicle having a frame structure comprising two longitudinal beams, wherein the cross-member comprises a main portion and two end-sections wherein each end section comprises an outer surface for facing an inner surface of a longitudinal frame beam wherein
the cross-member comprises at least one protrusion extending from the outer surface of the end-section for being introduced into a hole or notch of the frame beam for forming a form-lock to one or more components to be mounted to the longitudinal frame beam.

2. The cross-member according to claim 1 , wherein an outer portion of the protrusion is adapted for locking the component upwards and/or downwards relative the height direction of a vehicle.

3. The cross-member according to claim 1 , wherein an outer portion of the protrusion is adapted for locking the component relative the length direction of the longitudinal frame beam.

4. The cross-member according to claim 1 , wherein an outer portion of the protrusion is adapted for locking the component rotationally (R) relative a direction along the frame beams.

5. The cross-member according to claim 1 , wherein an outer portion is adapted for locking the component in transverse direction relative the length direction of the longitudinal frame beam.

6. The cross-member according to claim 1 , wherein an inner portion ( 12 a ) of the protrusion is arranged to form a form-lock to the frame beam.

7. The cross-member according to claim 1 , wherein the outer surface comprises a one or more additional protrusions, wherein the additional protrusions are arranged to form a form-lock between the cross-member and the frame beam.

8. The cross-member according to claim 1 , wherein the main portion comprises connection points for mounting additional functional components.

9. A vehicle comprising a cross-member according to claim 1 , wherein the cross-member is arranged between two longitudinal frame beams of the vehicle and the at least one protrusion extends through a longitudinal frame beam and forms a form-lock to the component, wherein the component comprises at least one recess with complementary shape compared to at least an outer portion of the at least one protrusion.

10. The vehicle according to claim 9 , wherein the component comprises additional connection points, for example threaded holes, for fixing the component to the protrusion; and/or to the frame beam.

11. The vehicle according to claim 9 , wherein the component to be connected to the frame beams is a driven wheel suspension module.

12. The vehicle according to claim 9 , wherein the component to be connected to the frame beams is an individual wheel suspension module.

13. The vehicle according to claim 9 , wherein the component is a driven or non-driven wheel suspension module which comprises to at least two suspension brackets which each comprise at least one recess with complementary shape compared to at least the outer portion of the protrusions for forming a form-lock to the cross-member.

14. The vehicle according to claim 9 , wherein a height between an upper and lower surface of the end-sections may be smaller than the height of the cross-member.

15. A method for mounting a component to a longitudinal frame beam of a vehicle comprising
a) providing a cross-member according to claim 1 ,
b) providing a component which has an essentially complementary shape compared to at least an outer portion of the at least one protrusion;
c) inserting the at least one protrusion into a hole or notch of a frame beam so that at least an outer portion of the protrusion extends through the hole or notch and at an outer surface of the frame beam; and
d) attaching the component to the frame beam by allowing the protrusion to be received in the recess of the component for forming a form-lock to the component.
