Control arm for a motor vehicle
A control arm for a motor vehicle includes a single-shell base body having a flat bottom and lateral legs which are formed by bending the bottom. Attached to the base body are plural bearings, with at least one of the lateral legs having a recess provided between two of the bearings.
1. A control arm for a motor vehicle, comprising:
a single-shell base body having a flat bottom and lateral legs which are formed by bending the bottom; and
plural bearings attached to the base body,
wherein at least one of the lateral legs has a recess provided between two of the bearings, wherein the recess has at least one area provided with a collar.
2. The control arm of claim 1 constructed as A-arm.
3. The control arm of claim 1 , wherein the recess extends in orthogonal relationship to a longitudinal axis of the motor vehicle.
4. The control arm of claim 1 , wherein the recess extends in orthogonal relationship to a transverse axis of the motor vehicle.
5. The control arm of claim 1 , wherein the recess has a polygonal configuration.
6. The control arm of claim 1 , wherein the recess is defined in a longitudinal direction by a length of 0.01 to 100 mm.
7. The control arm of claim 1 , wherein the recess is defined in a longitudinal direction by a length of 0.1 to 60 mm.
8. The control arm of claim 1 , wherein the recess is defined in a longitudinal direction by a length of 1 to 50 mm.
9. The control arm of claim 1 , wherein the collar extends in orthogonal relationship to the at least one of the lateral legs and has a length of 0.1 to 20 mm.
10. The control arm of claim 1 , wherein the collar extends in orthogonal relationship to the at least one of the lateral legs and has a length of 1 to 10 mm.
11. The control arm of claim 1 , wherein the recess is defined by a radius of 0.1 to 40 mm.
12. The control arm of claim 1 , wherein the recess is defined by a radius of 1 to 30 mm.
13. The control arm of claim 1 , wherein the recess is surrounded by a marginal area of a hardness which differs from a hardness of the base body.
14. The control arm of claim 13 , wherein the recess or the marginal region or both have at least one region which is heat treated.
15. A control arm for a motor vehicle, comprising:
a single-shell base body having a flat bottom and lateral legs which are formed by bending the bottom; and
plural bearings attached to the base body,
wherein at least one of the lateral legs has a recess provided between two of the bearings, wherein the recess has a toroidal configuration.
16. The control arm of claim 15 constructed as A-arm.
17. The control arm of claim 15 , wherein the recess extends in orthogonal relationship to a longitudinal axis of the motor vehicle.
18. The control arm of claim 15 , wherein the recess extends in orthogonal relationship to a transverse axis of the motor vehicle.
19. The control arm of claim 15 , wherein the recess has a polygonal configuration.
20. The control arm of claim 15 , wherein the recess is defined in a longitudinal direction by a length of 0.01 to 100 mm.
21. The control arm of claim 15 , wherein the recess is defined in a longitudinal direction by a length of 0.1 to 60 mm.
