Patent number: 11642927Abstract: A chassis link for a motor vehicle having load introduction elements connected by a straight profile portion of fiber-reinforced plastic. The profile portion and load introduction elements are connected via an adhesive connection in a common connection portion in which an end portion of the load introduction element and an end portion engage another in positive engagement. On both sides of a profile portion neutral fiber plane, the adhesive connection has longitudinal adhesive layers extending in a longitudinal direction of the profile portion and parallel to one another in a vertical. In vertical direction of the profile portion the longitudinal adhesive layers have a cross-sectional area becoming larger with increasing distance from the neutral fiber plane so that a relief is brought about in regions of the adhesive connection which have a relatively large distance from the neutral fiber plane in vertical direction of the profile portion.Type: GrantFiled: November 15, 2019Date of Patent: May 9, 2023Assignee: ZF FRIEDRICHSHAFEN AGInventors: Andre Stieglitz, Manfred Bürgmann, Ingolf Müller

Patent number: 11440364Abstract: 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.Type: GrantFiled: November 16, 2018Date of Patent: September 13, 2022Assignee: ZF FRIEDRICHSHAFEN AGInventors: Ingolf Müller, Manfred Bürgmann, Jens Heimann, Andre Stieglitz, Carsten Sohl, Valentin Hörtdörfer

Patent number: 11279190Abstract: An axle strut for a vehicle having a shaft and two bearing regions. The axle strut has a supporting profile and two load-introducing elements. The supporting profile is formed from fiber reinforced plastics composite material. A first load-introducing element and a second load-introducing element are arranged at respective bearing region, and the supporting profile is arranged spatially between the two bearing regions. The supporting profile has a first connection area facing the first bearing region and a second connection area facing the second bearing region. Every load-introducing element has a receptacle. The supporting profile is connected by its first connection area and by the receptacle of the first load-introducing element to the first load-introducing element by an adhesive connection, and the supporting profile is connected by its second connection area and by the receptacle of the second load-introducing element to the second load-introducing element by a further adhesive connection.Type: GrantFiled: March 27, 2018Date of Patent: March 22, 2022Assignee: ZF Friedrichshafen AGInventors: Thomas Rupflin, Thomas Schwarz, Andre Stieglitz, Philipp Bauer, Ingolf Müller, Manfred Bürgmann

Patent number: 11104195Abstract: A four-point link for a wheel suspension of a vehicle includes a core element, a filament and four bushings. The filament is pre-impregnated with a resin. The core element further has a torsional element and four support arms connected integral with the torsional element. The core element and the respective bushing are at least partially wrapped by the filament. The respective bushing for receiving a respective bearing element is arranged at a respective distal end of the respective support arm. The respective bushing has at least one anchor element, and at least one undercut is formed between the at least one anchor element and the bushing, and the core element engages in the undercut for connecting the bushing to the support arm of the core element by positive engagement.Type: GrantFiled: March 27, 2018Date of Patent: August 31, 2021Assignee: ZF FRIEDRICHSHAFEN AGInventors: Andre Stieglitz, Ingolf Müller, Philipp Bauer, Manfred Bürgmann, Patricia Nieke

Patent number: 11097584Abstract: A four-point link for a vehicle includes a core element and a main laminate comprising a fiber reinforced plastics composite material, which wraps around the core element. The core element comprises four load-introducing elements and a foam core, and the four load-introducing elements (4) are connected by positive engagement to the foam core (5). The four-point link has four additional windings, wherein a respective additional winding wraps around a first, second, third and fourth load-introducing element and operatively connects a respective one of the latter to the main laminate. Compressive forces can be introduced into the main laminate (3) by means of every additional winding (6).Type: GrantFiled: March 27, 2018Date of Patent: August 24, 2021Assignee: ZF FRIEDRICHSHAFEN AGInventors: Ingolf Müller, Manfred Bürgmann, Andre Stieglitz, Philipp Bauer
