Title
(EN) BALL AND SOCKET ASSEMBLY
(FR) ENSEMBLE JOINT A ROTULE
Abstract
(EN)
A ball and socket assembly may be used in an automotive suspension system. It may include a ball stud having a shaft portion extending from a ball portion, and a bearing having a wall portion defining an open end and an end portion defining a closed end, with the wall portion and the end portion further defining a cavity having the ball portion received therein, and with the open end of the wall portion including a radially outwardly extending seal flange. A shell has a sidewall portion including a generally cylindrical inner surface for receiving the bearing. The sidewall portion of the shell defines an open end face adjacent to the open end of the bearing, with the seal flange of the bearing extending radially outward of the cylindrical inner surface of the shell and substantially covering the open end face of the shell. Also, the assembly provides for securing the shell to the bearing. The assembly may also include a boot having a first open end and a second open end enclosing a portion of the bearing and the ball stud and defining a grease cavity therein, with the second open end including a flange portion disposed between the seal flange and the open end face of the sidewall, and with the first end of the boot sealingly engaging the shaft portion of the ball stud.

L'invention concerne un ensemble joint à rotule pouvant être utilisé dans un système de suspension d'automobile. Ledit ensemble peut comprendre un pivot à rotule présentant une partie axe s'étendant à partir d'une partie rotule, ainsi qu'un palier présentant une partie paroi définissant une extrémité ouverte et une partie d'extrémité définissant une extrémité fermée, la partie paroi et la partie d'extrémité définissant également une cavité dans laquelle est reçue la partie rotule, l'extrémité ouverte de la partie paroi comprenant une bride d'étanchéité s'étendant généralement radialement vers l'extérieur. Une enveloppe présente une partie paroi latérale comprenant une surface intérieure généralement cylindrique destinée à recevoir le palier. La partie paroi latérale de l'enveloppe définit une face d'extrémité ouverte adjacente à l'extrémité ouverte du palier, la bride d'étanchéité du palier s'étendant radialement vers l'extérieur de la surface intérieure cylindrique de l'enveloppe et recouvrant sensiblement la face d'extrémité ouverte de l'enveloppe. Ainsi, l'ensemble permet la fixation de l'enveloppe sur le palier. L'ensemble peut également comprendre un soufflet de protection présentant une première extrémité ouverte et une seconde extrémité ouverte renfermant une partie du palier et du pivot à rotule et définissant une cavité à graisse à l'intérieur, la seconde extrémité ouverte comprenant une partie épaulement disposée entre la bride d'étanchéité et la face d'extrémité ouverte de la paroi latérale, la première extrémité du soufflet de protection venant en contact de manière étanche avec la partie axe du pivot à rotule.
