Embodiment Construction

[0016] figure 1 The structural component 2 shown in FIG. 2 includes a first FKV component 2a and a second FKV component 2b, and the first and second FKV components are made of CFK, for example. The force transmission element 1 is used in the structural component 2 to realize a force transmission point.

[0017] The force transmission element 1 is designed as a hybrid component and includes a metal insert 3 made of steel, which is designed in a sleeve shape along the force transmission direction F when a through hole 9 is formed. The metal insert 3 is surrounded in a shell shape by a structure 4 composed of BMC material, the structure 4 having a substantially biconical cross section.

[0018] With the end side of the double cone shape, a contact surface 5 for abutting on the FKV component 2a and a contact surface 6 for abutting on the FKV component 2b are respectively formed. In addition, the contact surfaces 5 and 6 transition to flanges 4a and 4b, respectively, and the flanges 4a...

Abstract

The element (1) has a hollow cylindrical metal insert (3) which is fixed and enclosed in a plastic structure (4a,4b) having contact surface in for bearing against the fiber-plastic composite component (2,2a,2b) one plane vertically to the force application direction. The metal insert has undercuts (7,8) which are oriented in opposite directions. The plastic structure is double-cone-shape in the plane of force transmission direction. The base surface of double cone and contact surfaces of the plastic structure are made of bulk molding compound (BMC).

Description

Technical field [0001] The invention relates to a force-transmitting element for fixing in a fiber-plastic composite (FKV) component or on a fiber-plastic composite component. The force-transmitting element is designed as a hybrid component with a metal insert that fixes In a structure composed of synthetic materials. In addition, the present invention also relates to an FKV component as a structural part of a vehicle body, the FKV component having a force transmission point realized under the condition of using the force transmission element according to the present invention. Background technique [0002] DE 10 2008 061 463 A1 discloses such a force transmission element for FKV components, which is designed as an insert, which can form at least one defined load path in the structural part. Such inserts with metal inserts are made of FKV material, namely SMC material. However, the sheet molding compound (SMC) process used to manufacture this known insert is associated with hig...
