Embodiment Construction

[0032] The diagonal brace arrangement according to the invention relates to a so-called frame structure such as is shown in the drawings.

[0033] The diagonal strut arrangement 1 consists of four pultruded fiber-reinforced plastic profile struts 2 which are connected to each other by a central light metal joint 3 joined together. Of course, other numbers of struts are also possible, for example six struts. The bonded connecting joint element 4 designed for connection to the underbody of the motor vehicle is likewise made of light metal material. A diagonal brace arrangement 1 designed in this way can be fastened to the floor during assembly or even in the frame structure. This can be achieved by the engaging connection joint element 4 , which can have corresponding engaging aids.

[0034] By using a light metal material for the joints 3, 4, the weight advantage of the fiber reinforced plastic strut 2 can be maintained. Light metal materials have a density of 5g / cm 3 The f...

Abstract

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.

Description

technical field [0001] The invention relates to a diagonal strut arrangement for a reinforced mounting on the underbody (underframe) of a motor vehicle. Furthermore, the invention relates to a method for producing a diagonal strut arrangement and a motor vehicle underbody using the diagonal strut arrangement. Background technique [0002] Diagonal struts for mounting on the underbody of a motor vehicle are known for increasing the torsional rigidity. This is especially important in convertibles with self-supporting bodies, which lack a solid roof structure. The tensile and compressive forces in the area of ​​the outer edge of the body, for example above the spare wheel well, are introduced via the diagonal struts into an area located further inside, closer to the vertical longitudinal center plane of the vehicle. These tensions and compressions are caused by undesired vibrations and torsions of the bodywork that may occur during operation of the vehicle, thereby impairing ...
