The invention is directed to a multipoint link () for an undercarriage of a vehicle, comprising a core element () formed from a foamed material and at least one roving () of bundled continuous filaments wound around the core element (), wherein the at least one roving () winding around the core element () in at least one layer forms an outer layer of the multipoint link (), wherein the core element () is constructed as a hollow body which comprises at least two shell elements ().

Multi-point link for an undercarriage of a vehicle

A multipoint link for an undercarriage of a vehicle, having a core element formed from a foamed material and at least one roving of bundled continuous filaments wound around the core element, the at least one roving winding around the core element in at least one layer forming an outer layer of the multipoint link. The recesses serving to guide the at least one roving to be laid by winding are incorporated in the surface of the core element.

A method for producing a component by a 3D winding method, a filament or a plurality of parallel filaments having a fiber-reinforced plastic composite material is or are laid down on a core in a combination of a plurality of different winding patterns. Every filament is preimpregnated. Every winding pattern influences at least one mechanical characteristic of the component. The mechanical characteristics of the component are selectively adjusted by the sequence, repetition, mixing, and material selection of the individual winding patterns.

Method for producing a component, and component

A four-point link () for a wheel suspension of a vehicle, having a core element (), a thread () and four bushings (). The thread () is pre-impregnated with a resin. The core element () has a torsional element () and four supporting arms () integrally connected to the torsional element (). A bushing () is arranged, on each respective distal end of the supporting arms (), for holding a respective bearing element. The core element () and the respective bushings () are at least partially wrapped with the thread () in order to connect the bushing (), in each case, to the thread () at least in a non-positive manner. In addition, a method for producing the above-mentioned four-point link ().

Four-point link

A plastic component, with fiber reinforcement, for use in a motor vehicle. The plastic component comprises a number of fiber layers connected to one another by injection of plastic and by a pressing force. The plastic component comprises at least two structural parts which overlap one another a pressing direction such that the die comprises at least one upper die portion formed with a pressing unit for applying a pressing force in the pressing direction, and at least one lower die portion which cooperates with the upper die portion to form a cavity in which the plastic component is formed. A die insert is fitted in the die and can move by and with the upper die portion and is designed to transmit the pressing force to the at least one structural part of the plastic component which is overlapped by the other structural part of the plastic component in the pressing direction.
