  • Patent number: 9919742
    Abstract: A vehicle body has an underbody structure and an auxiliary frame fastened thereto, which supports components of a wheel axis of the vehicle. The auxiliary frame is connected to the underbody structure without interposition of elastomer bearings or the like by use of several adhesive beads. The adhesive beads are configured not only with regard to a connection that meets mechanical requirements, but in particular with regard to the thickness the adhesive beads are also configured for acoustic insulation. The auxiliary frame is additionally supported on a securing structure provided below the auxiliary frame with the interposition of an acoustic insulation layer. The securing structure is connected to the underbody structure in a force-fit or material fit manner.

  • Patent number: 9561700
    Abstract: A connecting arrangement between a wheel-guiding link of a vehicle wheel suspension and a flange of a carrier or similar uses a bolt, which bolt passes through a longitudinal hole in the carrier flange or the link. A cutting structure is provided that separates the wall of the longitudinal hole if a sufficiently strong tensile or compressive force is exerted against the wall, thereby enabling the connecting arrangement to be undone. The cutting structure may be provided on the bolt, on a nut screwed thereon, on a disc between the flange or the link and the nut or the head of the bolt, or may be held in the longitudinal hole on a wall section.

  • Patent number: 7048286
    Abstract: A rear axle of a passenger vehicle whose wheel mount is guided by five individual suspension links, at least two of which are coupled above the midpoint of the wheel and at least two are coupled essentially beneath the midpoint of the wheel, and the so-called steering rod as the fifth link is coupled behind the midpoint of the wheel (as seen in the direction of travel). The two upper transverse links are situated in front of a spring element (as seen in the direction of travel) and/or a shock absorber element, which is located between the vehicle body and one of the lower suspension links. The steering rod is pitched at an angle of sweep with respect to the transverse direction of the vehicle. The coupling points on the wheel mount side of the two upper suspension links and/or the lower suspension links are offset in height with respect to one another and neither the two upper suspension links nor the lower transverse link and the (lower) frame side bar describes a common plane.

To create a compact configuration, the two upper transverse links are situated in front of a spring element (as seen in the direction of travel) and/or a shock absorber element, which is located between the vehicle body and one of the lower suspension links. To improve the elastokinematic behavior, the steering rod is pitched at an angle of sweep with respect to the transverse direction of the vehicle, this angle being on the order of magnitude of 5° to 25°.
