  • Patent number: 5318373
    Abstract: A ball joint for chassis parts in motor vehicles is described, in which a hinge pin 1 with a spherical part 2 is mounted in a housing 3 by a bearing box 4. The hinge pin is led through an opening 6 out of the housing 3. The housing 3 is sealed by a lid 7, on the opposite side. In this case, the housing is placed in a rigid external bushing 10 with an elastomer sleeve 9 surrounding the housing. Radial surfaces on the housing 3, as well as on the external bushing 10, limit the axial movement of the housing 3 with respect to the external bushing. The radial surfaces of the housing 3 are formed by the two flat sides of a collecting plate 15, which can be firmly connected to the housing 3 first in the assembly of the joint. The collecting plate 15 engages with an axial moving space between arranged radial surfaces of the external bushing 10.
