Claims
- 1. A control arm as suspension component for a motor vehicle, comprising a hollow steel structure of steel sheets which are at least partially pressed and welded together, and a reinforcing sheet provided in a predetermined area of the steel structure for increasing a resistance against buckling.
- 2. The control arm of claim 1, wherein one of the steel sheets is formed by a U-shaped troughed shell having a base and legs extending from the base and terminating in free ends, wherein the other one of the steel sheets is formed as an element selected from the group consisting of a transverse sheet and a complementary U-shaped sheet, having opposite ends which are welded to the free ends of the shell, thereby bounding an interior space, wherein the reinforcing sheet is welded in the interior space between the legs.
- 3. The control arm of claim 1, configured as a transverse control arm of substantial L-shape, wherein the steel sheets are interconnected by a central curved mid-section, wherein the reinforcing sheet is welded to the length section.
- 4. The control arm of claim 2, wherein at least one of the base and legs of the shell has a crease-like depression for realizing an increased twist stiffness and rigidity.
- 5. The control arm of claim 1, wherein the reinforcing sheet has a crease-like depression for realizing an increased twist stiffness and rigidity.
- 6. A control arm for a suspension, comprising:
a first U-shaped shell having a base and legs extending from the base and terminating in free ends; a connecting member having opposite ends which are welded to the free ends of the shell, thereby bounding an interior space; and a reinforcing sheet welded in the interior space between the legs.
- 7. The control arm of claim 6, wherein the connecting member is a transverse sheet.
- 8. The control arm of claim 6, wherein the connecting member is a second U-shaped shell complementing the first U-shaped shell.
