Abstract
A sealing assembly of a ball joint, in particular for a vehicle, comprises a retaining ring which includes a ring axis and a radial ring flange having a flange upper side and an opposed flange lower side, and a sealing element which rests against the flange upper side and against the flange lower side and is exclusively connected to the retaining ring with an interlocking fit, the interlocking fit being configured such that the retaining ring and the sealing element are fixed to each other free of play in the axial and in the radial direction, and the flange upper side having an exposed contact surface for a sealing bellows.
Claims8
A ball joint including a sealing bellows and a sealing assembly comprising:
- a retaining ring which includes a ring axis and a radial ring flange having a flange upper side and an opposed flange lower side, and
- a sealing element which rests against the flange upper side and against the flange lower side and is connected to the retaining ring with an interlocking fit,
- the interlocking fit being configured such that the retaining ring and the sealing element are fixed to each other free of play in the axial and in the radial direction, and
- the flange upper side having an exposed contact surface for the sealing bellows,
- wherein the radial ring flange extends radially outwards and forms an outer peripheral edge, the radial ring flange being bent inwards at the outer peripheral edge so that at least parts of the radial ring flange are configured with two layers, wherein the sealing element extends between the two layers of the radial ring flange, and
- wherein the radial ring flange contacts the sealing bellows exclusively at the exposed contact surface of the flange upper side.
