Abstract
A chassis component (1) for a wheel suspension having at least two pivot points (3, 4), at least one connecting structure (7) which interconnects the pivot points (3, 4) with one another, and at least one sensor (9). The at least one sensor (9) is embodied as a piezoresistive thin film (19) arranged on a section of a surface (8) of the connecting structure (7). A thin film interconnects contact points (15, 16), of at least two conductive sections (13, 14) which are integrated in the connecting structure (7), to one another.

A chassis component, for a wheel suspension, comprising:
- at least two pivot points,
- a connecting structure connecting the two pivot points to one another, the connecting structure having an outer surface,
- at least two conductive sections, each of the conductive sections having contact points, the conductive sections are integrated into the connecting structure such that only contact points of the conductive sections emerge at the outer surface of the connecting structure,
- at least one sensor being formed as a piezo-resistive thin film,
- the piezo-resistive thin film being poured or sprayed onto a section of the outer surface of the connecting structure such that the sensor connects the contact points of the conductive sections to one another.
A method for producing a chassis component so that the chassis component has at least two pivot points and a connecting structure, the connecting structure is made from a plastic or at least a fiber composite material, and the chassis component is provided with at least one sensor, the method comprising:
- integrating at least two conductive sections in the connecting structure in such a manner that only contact points of the at least two conductive sections emerge at an outer surface of the connecting structure and are connected to one another by a sensor,
- forming the sensor as a piezo-resistive thin film, and
- pouring or spraying the piezo-resistive thin film onto a section of the connecting structure.
