Patent number: 5286131Abstract: A ball joint has a stud with a ball end disposed in a housing in abutting engagement with an improved bearing. The bearing has a plurality of segments disposed in a circular array. A plurality of flexible connector sections interconnect the segments. As originally formed, the bearing has generally cylindrical outer side surface with a diameter which is less than the diameter of an inner side surface of the housing. This facilitates insertion of the bearing into the housing during assembly of the ball joint. The ball end of the stud applies force against a circular array of bearing segments to expand the circular array of bearing segments outwardly into engagement with the inner side surface of the housing. The bearing segments are interconnected by flexible connector sections which are deflected, as the bearing segments move outwardly, to accommodate expansion of the circular array of bearing segments.Type: GrantFiled: August 17, 1992Date of Patent: February 15, 1994Assignee: TRW Inc.Inventor: Ruey E.

Patent number: 4684279Abstract: A ball joint of the type having a ball stud and preformed plastic socket includes means for sealing the stud head receiving socket opening and assuring the maintenance of the seal in spite of accumulated tolerance variations. A cap with an inwardly converging peripheral closure surface fits within and conforms closely to a matching closure surface in the socket opening. Deformable protuberances on the outer side of the cap are engaged and deformed by a surface of the suspension control arm to which the socket is mounted, or by a surface of a cover which fixes the socket to the control arm. The protuberances extend far enough from the cap outer side to assure that engagement and deformation in spite of accumulated tolerance variations in the components of the ball joint. The deformation forces the cap into the socket opening as the ball joint is completed to engage the closure surfaces more tightly and assure maintenance of the seal of the socket opening.Type: GrantFiled: August 1, 1986Date of Patent: August 4, 1987Assignee: General Motors CorporationInventor: Frederick C.

Patent number: 4386869Abstract: Integrally sealed vibration dampening ball and socket joints having a spherical member capable of swivelling relative to a socket member. A split metallic or high strength plastic bearing ring disposed with clearance in a shell has a concave spherical surface portion in swivelling engagement with the ball member, and a pair of symmetrically disposed resilient rings installed between the bearing ring and the inner surface of the shell constantly urge the bearing surface of the bearing ring in engagement with the spherical member surface to prevent rattle and to compensate for wear. Normal loads are taken by the resilient rings, and overload and shock load are taken by the bearing ring. A bellows seal, formed integrally with one of the resilient rings or, alternatively, formed separate is fastened at one end in the shell. The bellows seal is held elastically at its other end around a portion of the spherical member.Type: GrantFiled: July 24, 1981Date of Patent: June 7, 1983Assignee: Gulf & Western Manufacturing CompanyInventor: Joseph E.

Patent number: 4035094Abstract: An improved ball and socket joint usable in a steering system includes a stud having an enlarged head or ball portion and a socket having a cavity closed by an end cap, the socket cavity being adapted to receive the stud head therein. An expander, such as a belleville spring, is resiliently compressed between the end cap and the head. The expander is the sole item interposed between the end cap and the head and serves the dual role of expander and supplemental seat for the head. The expander has a center opening, through which the head directly contacts the end cap and is pre-loaded by it. As the assembly sustains wear, the expander comes into play to maintain loading on the head and to keep the head seated on the expander. Problems of tolerance stackup are avoided by preloading the end cap directly by the head, and utilizing the expander as the supplemental seating means. By initially compressing the expander to a fully flattened state, travel of the expander to full relaxation is available to take up wear.Type: GrantFiled: March 11, 1976Date of Patent: July 12, 1977Assignee: TRW Inc.Inventor: Edward J.
