Control arm and method for producing same

1. A control arm for a motor vehicle which is substantially formed by a fiber-plastic composite structure,

the fiber-plastic composite structure having at least one of a ball joint and elastomer bearing,

the fiber-plastic composite structure being formed integrally and in a materially-locking manner without any reinforcement structure,

either the elastomer bearing or the ball joint is integrated into the control arm in at least one of a form-locking manner and a materially-locking manner at at least one bearing location, and

the elastomer bearing or the ball joint is integrated into the control arm by a perforated support structure, and the support structure is formed from either light metal or a fiber composite material.

2. The control arm according to claim 1 , wherein the fiber-plastic composite structure is produced from a load-adapted preform structure, and the preform structure is at least one of:

produced as a flat, at least one-layer textile by using at least one of a tailored fiber placement method and a Jacquard method, and

formed from at least one of a fiber-matrix combined material, a commingling material and a film stacking material having multiple layers.

3. The control arm according to claim 1 , wherein a load adaption is formed by fiber orientation on the preform structure in a form of hybrid yarns which are at least one of introduced singly and plurally at least one of on top of one another other and next to one another.

4. The control arm according to claim 1 , wherein the bearing location, in a form of a means for receiving the elastomer bearing or the ball joint, is formed by a bush integrated into the control arm, which comprises at least one of plastic, aluminum alloy, magnesium alloy, glass fiber plastic material and carbon fiber plastic material.

5. The control arm according to claim 4 , wherein the bush is connected to the fiber-plastic composite structure in a materially-locking manner, and is either molded on the fiber-plastic composite structure or bonded to the fiber-plastic composite structure.

6. The control arm according to claim 1 , wherein a means for receiving the elastomer bearing or the ball joint, formed from the fiber-plastic composite structure, forms a first part of either a bearing bush or a joint housing, to which at least one additional housing part attaches in a form-locking manner, for receiving the elastomer bearing or a ball pivot of the ball joint, and the first part of the bearing bush or the joint housing and the additional housing part are connected to one another in at least one of:

a materially-locking manner,

a form-looking manner, and

a force-locking manner.

7. The control arm according to claim 6 , wherein the connection of the first part of the bearing bush or the joint housing and the additional housing part is formed by at least one of bonding, riveting, injection, thermoplastic overmolding and thermosetting overmolding.

8. The control arm according to claim 6 , wherein the additional housing part is formed from a light metal material and at least one additional material is inserted between the first part of the bearing bush or the joint housing and the additional housing part by at least one of thermoplastic overmolding and thermosetting overmolding.

9. The control arm according to claim 1 , wherein at least one sensor is integrated into the fiber-plastic composite structure, and the at least one sensor detects changes in the fiber-plastic composite structure so as to inform of either overstressing or overloading.

10. The control arm according to claim 1 , wherein either an adjustment device is integrated into the control arm such that the control arm is length adjustable, or

the control arm has a displaceable tie rod.

11. The control arm according to claim 10 , in combination with a steering mechanism.
