Control arm hits the frame

Thank you for the fast answers!

On the picture shown above the torsion bar is not installed --> this is not a picture of my car. I just took it from a another thread to show you what what my problem is. And I don't know the name of the part in the red circle.

In my case the torsion bar is - of course - installed. When I am driving on a bumby road or when I pass a gully some noise is coming out of the front of my car. I took a look and saw deep scratches on the frame - right on the place where the "finger" of the control arm is moving up and down.
