DIAGONAL STRUT DEVICE, METHOD FOR MANUFACTURING SAME AND MOTOR VEHICLE UNDERFLOOR REINFORCED BY MEANS OF DIAGONAL STRUCTURE DEVICE

摘要

A diagonal strut device (1) for reinforcing arrangement on an undercarriage of a motor vehicle. The diagonal strut device (1) has a plurality of struts (2) made from a fibre-reinforced plastic composite material, which extend away from a central joint element (3). Each strut (2) can be connected to the undercarriage via it's 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). 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 firmly bonded cast joint. Further, a method for the production of a diagonal strut device (1), as well as a motor vehicle undercarriage, which uses the diagonal strut device (1) for reinforcement.
