Problems solved by technology

[0005] Forces acting unilaterally and transversely to the through-opening of the component via the lever arm of the connecting element produce a tilting or bending moment in the device, which additionally promotes vibratory frictional wear on the plastic component and ultimately leads to a failure of the connection. Early failure (refer to Figure 1, device belonging to the prior art)

Embodiment Construction

[0038] FIG. 1 shows a device according to the prior art for introducing forces into a plate-like component 1 made of fiber composite material. A bolt 3 passing through a bore 2 of the component 1 is connected to the component 1 by means of a screw connection. A structural element, not shown, acts on a free end of the screw 3 . The plane of the structural member is parallel to the plane of the plate resulting in a transverse force F Q A transverse force, in particular still dynamic, is introduced pointwise into component 1 on one side of component 1 and via the lever arm of screw 3 . Even though the bolt 3 is clamped axially positively and nonpositively to the component by means of a threaded connection, there is no protection against overturning or the bending moment M B and thus the inclination of the bolt 3 in the hole 2 of the component 1 . During the continuous load caused by the force-introducing structural parts, the vulnerable hole inner side 4 of the hole 2 is subje...

Abstract

The invention relates to a device for introducing force into a component of fiber composite material by means of a screw connection having a bolt-like connecting element arranged in a passage of the component. The invention is based in particular on the object of improving the durability of the screw connection on the component of fiber composite material. The object is achieved in that the screw connection has a two-part bush (6) which borders the passage (2) of the component (1) and accommodates the connecting element (9), wherein the first and the second bush part (6.1, 6.2) of the bush (6) are designed to engage in one another in axial extension, and each bush part (6.1, 6.2) has a radially extended union collar (15.1, 15.2) with a collar side (16.1, 16.2) facing the component (1), on which side a sliding surface is formed.

Description

technical field [0001] The invention relates to a device for introducing force into a component made of fiber composite material by means of a screw connection, which comprises a pin-like connecting element arranged in a through-opening of the component. Background technique [0002] The device is used on structural elements to be connected point-by-point with elements made of softer materials, such as panels made of fiber-reinforced plastic, wherein the forces acting on the structural element are transmitted to the in the components. The known connection essentially consists of a connecting element, usually made of metal, which passes through the plastic component and which is screwed to the component in a manner similar to a screw connection. Such devices are used, for example, in the field of motor vehicle technology in wheel suspensions or in transverse control rod connections on fiber composite components. [0003] In particular, dynamically acting forces are introduc...
