摘要:
A ball joint for different applications in special car suspension is disclosed. The ball joint includes a pin (1) with a first end for fixing in a counterpart, and a second spherical end (2), that is encased in a bearing (3) of consequently spherical internal profile, that by its turn is mounted in the internal area of a housing (4), whose external area is intended for fixing in a second counterpart. The housing (4) is closed over a retaining ring (5), that by its turn presses the bearing (3) and the pin (1), in such a way as to prevent axial or radial moving between the parts, including the dismounting of the assembly, but allowing rotational and oscillatory movements required for the operation of the assembly. Further, the retaining ring (5) supports the external (6) and the internal (7) sealings, preferably vulcanized, both of the area between the retaining ring (5) and the housing (4) and of the area between the retaining ring (5) and the pin (1). In this area the part of the sealing next to the pin (1) is strained by a sealing ring (8) that produces the desired sealing effect between the parts.
