Abstract

A ball and socket joint has a bearing insert (12) of a resilient material retained within a cup-shaped cavity (15) in a housing (10), the bearing insert (12) being retained in the cavity (15) by a recess (17) in the cavity (15) into which an end portion (22) of the bearing insert is biassed, as the relaxed open end diameter of the insert is greater than that of the aperture (14, Fig. 1, not shown) of housing (10). <IMAGE>

Description

SPECIFICATION A ball and socket joint This invention relates to ball and socket joints.
It is known for example from GB 1 323 047 to provide a ball and socket joint in which a bearing insert of a resilient material is retained within a cup shaped cavity in a housing. The bearing insert in such a ball and socket joint forms a part spherical bearing surface by partially enclosing the ball of the ball pin, the ball pin having a shank which extends through an aperture in the housing.
It is usual in such a ball and socket joint to retain the bearing insert in the housing by an end cap or ring held in the mouth of the aperture by radially inwardly deforming the housing.
Such an operation requires considerable force to be exerted upon the housing in order to plastically deform it. If the housing is incorrectly supported during this operation unwanted distortion of the housing can occur which will result in a stiff joint being produced. With such an assembly method it is difficult to maintain the components in position while fitting the end cap or ring and at the same time ensure that sufficient enclosing a part spherical head of the ball pin, the bearing insert having an end portion which before

With such an assembly method it is difficult to maintain the components in position while fitting the end cap or ring and at the same time ensure that sufficient enclosing a part spherical head of the ball pin, the bearing insert having an end portion which before assembly has an outside diameter which is greater than the internal diameter of the co-operating portion of the housing whereby the end portion of the bearing insert engages a recess in the housing adjacent to the aperture of the housing to retain the bearing insert within the cavity.
  2. 2. A ball and socket joint as claimed in Claim 1 in which the recess is a circumferential groove.
  3. 3. A ball and socket joint as claimed in Claim 1 or in Claim 2 in which the end portion has lip for engagement with the recess in the housing.
  4. 4. A ball and socket joint as claimed in any preceding claim in which the end portion is a thickened end portion having a cylindrical bore of substantially the same diameter as the part spherical head of the ball pin
  5. 5. A ball and socket joint substantially as herein described with reference to the accompanying drawings.
