  • Patent number: 11872865
    Abstract: A multi-link motor vehicle axle for the attachment of a wheel carrier to a motor vehicle body. The axle includes a first link plane and a second link plane. A first transverse link and a second transverse link are assigned to the first link plane. The second link plane includes a trapezoidal link which is attached by way of a first coupling link to the wheel carrier and by way of a second coupling link to the motor vehicle body. A longitudinal link of the multi-link motor vehicle axle is formed, which longitudinal link is connected, at its longitudinal link end facing away from the second link plane, to the motor vehicle body. The longitudinal link is attached, by way of its longitudinal link end facing toward the second link plane, to the trapezoidal link.

  • Publication number: 20150063732
    Abstract: A bearing element having a bearing core and having a bearing sleeve, wherein a bearing body is arranged between the bearing core and the bearing sleeve and wherein a protective cap protects the bearing body against environmental influences. To reliably fix the protective cap to the bearing element, that the protective cap is fixed by a closure part, wherein the closure part engages around the bearing element and is formed by two half-shells which are of substantially symmetrical form, wherein the closure part both engages around the bearing element and also surrounds at least one section of a control linkage of a running gear of a motor vehicle and protects said section against high temperatures.
