Abstract

A ball and socket joint (1) is provided, for example, for a chassis bearing, with a ball (2), a pivot (3) originating from the ball (2), a housing (4) accommodating the ball, and a sealing bellows (5), which extends between the housing (4) and the pivot (3) and has a housing-side opening (6) and a pivot-side opening (7). The sealing bellows (5) has a circumferential sealing lip (8) for sealing at the pivot-side opening (7). The ball and socket joint (1) has a first guide ring (9), which guides the sealing bellows (5). The first guide ring (9) is arranged at the pivot (3). An especially favorable functional separation is achieved as a result between the guiding function and the sealing function.

Independent Claims | See all claims (19)

  1. 1. A ball and socket joint comprising: a ball; a pivot originating from said ball; a housing accommodating said ball; a sealing bellows, which extends between said housing and said pivot and has a housing-side opening and a pivot-side opening, wherein said sealing bellows has a circumferential sealing lip for sealing at said pivot-side opening; and, a first guide ring, which guides said sealing bellows, said first guide ring being arranged at said pivot wherein said first guide ring includes a first axial section, which is arranged fixed statically to said pivot and with which said sealing lip is in contact, and a second axial section, by which said sealing bellows is guided, said second axial section being spaced a greater radial distance from said pivot than said first axial section, wherein said sealing bellows has a second guide ring cooperating with said first guide ring for guiding said sealing bellows relative to said pivot, said second axial section of said first guide ring extends into an axial groove of said second guide ring.
  2. 13. A ball and socket joint comprising: a ball; a pivot originating from said ball; a housing accommodating said ball; a sealing bellows, which extends between said housing and said pivot and has a housing-side opening and a pivot-side opening, wherein said sealing bellows has a circumferential sealing lip for sealing at said pivot-side opening; and a first guide ring, which guides said sealing bellows, said first guide ring including a first axial section fixed to said pivot for movement therewith, said first guide ring defining a sealing surface with which said sealing lip is in contact, a radial section extending away from said pivot and a second axial section extending axially from said radial section at a location spaced from said first axial section, said second axial section being spaced a greater radial distance from said pivot than said first axial section; and a second guide ring connected to said sealing bellows and cooperating with said first guide ring for guiding said sealing bellows, said second guide ring including a section fixed to said sealing bellows and a groove section defining a groove having an axial groove extent, said second axial section of said first guide ring extending into said groove.
