Method for producing a rail-shaped hybrid component, and such a hybrid component

A method for producing a rail-shaped hybrid component, the component comprising:

• a first profile rail extending in a longitudinal profile direction and being made of a carbon-fiber reinforced plastic material, said first profile rail having a first bar;
• and
• a second rail component made of a titanium material, said second rail component having a first connecting portion with a first inner face and a second connecting portion with a second inner face that faces the first inner face and is located at a distance therefrom;
• wherein a bar portion, extending in the longitudinal profile direction of the first bar of the first profile rail, is arranged between the first inner face of the first connecting portion and the second inner face of the second connecting portion, and the first and the second connecting portion of the second rail component are each cohesively connected to the first bar of the first profile rail,
• wherein the first and the second connecting portion of the second rail component are connected together by a cross bar extending in a transverse profile direction extending transversely to the longitudinal profile direction,
• the method having the following steps of:
• positioning the second rail component made of a titanium material on the first bar, extending in a longitudinal profile direction, of the first profile rail that is made of a carbon-fiber reinforced plastic material and moved in an advancing direction, in a fixed position relative to said first profile rail such that a bar portion, extending in the longitudinal profile direction, of the first bar is arranged between the first inner face of the first connecting portion of the second rail component and the second inner face, facing the first inner face and located at a distance therefrom, of the second connecting portion of the second rail component;
• cohesively connecting the second rail component to the first profile rail by a predetermined force being exerted perpendicularly on a first outer face, oriented in the opposite direction to the first inner face of the first connecting portion;
• applying ultrasonic vibration parallel to the first outer face by means of a first sonotrode of an ultrasonic welding device;
• simultaneously exerting a predetermined force perpendicularly on a second outer face, oriented in the opposite direction to the second inner face of the second connecting portion;
• and
• applying ultrasonic vibration parallel to the second outer face by means of a second sonotrode of the ultrasonic welding device.
