  • Patent number: 10570951
    Abstract: A method of producing a chassis module (1) with a structural component (3) having a through-going aperture (5) into which a ball joint housing (7) is inserted. An outer periphery of the ball joint housing (7) is connected all round to an edge section (9) of the aperture (5) by a first material-cohesive joining (11) without a filler. In order to stabilize the ball joint housing (7) in the aperture (5), the ball joint housing (7) is additionally connected all round to an inner wall section (13) of the aperture (5) at a location spaced away from the edge section (9), by a second material-cohesive joining (15) without a filler. The chassis module (1) is produced by the method, and the chassis module is in the form of a flanged connector (1) or a multi-point link.

  • Publication number: 20170129040
    Abstract: A method of producing a chassis component which includes a housing that is connected to a structural component by a weld. A receiving opening is formed in the structural component and the housing is pushed into the receiving opening, where a surface on the housing and a surface on the structural component are in contact with one another. At least one of the two surfaces in contact is formed as an oblique surface relative to the other of the two surfaces so that, before welding, a line contact exists between the two surfaces. Alternatively, the receiving opening in the structural component can be made slightly undersize relative to the housing geometry that is pushed into the receiving opening.
