A diagonal strut device (1) for reinforcing arrangement on an undercarriage of a motor vehicle. A plurality of struts (2) made from a fiber-reinforced plastic composite material extend away from a central joint element (3). Each strut (2) can be connected to the undercarriage via this from the end facing away from the central joint element (3). For this, a connecting joint element (4) is arranged on the end of each strut (2) facing away from the central joint element (3), wherein the central joint element (3) and the connecting joint elements (4) are formed from a light metal material. The central joint element (3) and the connecting joint elements (4) are then connected to the struts (2) by an at least positive connection. The central joint element (3) and the connecting joint elements (4) are each formed from several individual elements joined together.

1. A diagonal strut device (1) for reinforcing arrangement on an undercarriage of a motor vehicle, wherein the diagonal strut device (1) comprises: a central joint element (3), anda plurality of struts (2) made from a fibre-reinforced plastic composite material, which extend away from the central joint element (3), wherein each strut (2) can be connected to the undercarriage via this end facing away from the central joint element (3),wherein a connecting joint element (4) is arranged on the end of each strut (2) facing away from the central joint element (3) to provide the connection to the undercarriage,wherein the central joint element (3) and the connecting joint elements (4) are formed from a light metal material,wherein the struts (2) have an adhesion-improving coating added to them at least at their end sections, at which the formfitting connection is provided, which provides a structured surface, andwherein the central joint element (3) and the connecting joint elements (4) are formed respectively from several joined individual elements, and are connected to the struts (2) by mechanical clamping of an at least formfitting connection. 2. The diagonal strut device (1) according to claim 1, wherein the joined individual elements of the central joint element (3) and/or the connecting joint elements (4) are welded, soldered or adhered or connected to one another by additional connecting elements such as screws, rivets, nails or cotter pins. 3. The diagonal strut device (1) according to claim 1, wherein the struts (2) have openings and/or structures at their end sections, which are permeated and/or enclosed formfittingly by suitable structures of one or several individual elements of the central joint element (3) and/or the connecting joint elements (4). 4. The diagonal strut device (1) according to claim 1, wherein the diagonal strut device (1) comprises connecting aids, by means of which the diagonal strut device (1) can be connected to the undercarriage, wherein the connecting aids are provided on the connecting joint element (4) and comprise bore-holes, inserts, screw threads, adherends, clinch elements and/or weld contact areas. 5. The diagonal strut device (1) according to claim 1, wherein the central joint element (3) and/or the connecting joint elements (4) are additionally connected to the struts (2) by a formfitting connection, in particular by riveting or screwing (5). 6. The diagonal strut device (1) according to claim 1, wherein the struts (2) are fibre-reinforced plastic pultrusion profiles (2), in particular having a fibre proportion of up to 70% with respect to the total weight of the fibre-reinforced plastic pultrusion profile. 7. The diagonal strut device (1) according to claim 1, wherein the diagonal strut device (1) comprises up to four struts (2), which are arranged slanted towards one another at the central joint element (3), such that the central joint element (3) is separated from a plane that fixes the fastening element (4). 8. The diagonal strut device (1) according to claim 1, wherein the diagonal strut device (1) comprises four struts (2), which are arranged in an X-shape on the central joint element (3), and/or which are arranged slanted towards one another at the central joint element (3), such that the central joint element (3) is separated from a plane that fixes the fastening element (4). 9. The diagonal strut device (1) according to claim 1, wherein the light metal material is a light metal or a light metal alloy, in particular an aluminium or magnesium alloy.
