CA 2196511

A joint assembly (10) includes a metal housing which encloses a head end portion (24) of a movable stud member (22). A metal outer (30) bearing engages the head end portion (24) of the stud member (22). The outer bearing (30) has a cylindrical outer side surface (44) with a diameter which is larger than a diameter of a cylindrical inner side surface (42) of a chamber (18) in the housing (12) . The outer bearing (30) is retained against movement relative to the housing (12) by an interference fit. During fabrication of the joint assembly (10), a spring (34) and inner bearing (32) are inserted into the housing (12). An interference fit is established between the outer bearing (30) and the housing (12) by sliding the cylindrical outer side surface (44) of the outer bearing along the cylindrical inner side surface (42) of the chamber (18) in the housing. A rim portion (58) of the housing is then deformed or swaged over the outer bearing (30) to form a lip (64) which further retains the outer bearing in the housing.

Un joint (10) comprend un logement métallique qui renferme la tête (24) d'un goujon mobile (22). Un roulement extérieur métallique (30) pénètre dans la tête du goujon (22). Le roulement extérieur (30) comporte une paroi extérieure cylindrique (44) dont le diamètre est supérieur au diamètre de la paroi intérieure cylindrique d'une chambre (18) à l'intérieur du logement. Un ajustement avec serrage empêche tout mouvement du roulement extérieur (30) par rapport au logement (12). Au moment de la fabrication du joint (10), un ressort (34) et un roulement intérieur (32) sont introduits dans le logement (12). Le coulissement de la paroi cylindrique extérieure (44) du roulement extérieur le long de la paroi intérieure cylindrique de la chambre (18) à l'intérieur du logement établit un ajustement avec serrage entre le roulement extérieur (30) et le logement (12). Une bordure (58) du logement est alors déformée ou emboutie par-dessus le roulement extérieur (30) pour former une lèvre (64) qui aide à retenir le roulement extérieur à l'intérieur du logement.
