Abstract: The subject of the invention is a ball joint for motor vehicles with a bearing shell arranged between a joint housing and a ball head. The shell is provided at one end with elastically deformable ribs projecting from a stop surface. So that the ribs, after compensating for production tolerances, can absorb, in the elastically deformable zone, additional axial shock loads occurring in driving operation, it is proposed that the ribs be designed as square ribs, running radially, and separated by grooves from the stop surface adjoining their side walls, while the volume of each rib projecting above the stop surface, before mounting, is approximately equal to the free volume of the two grooves adjacent to it, so that the side walls of the grooves lying next to the stop surface act in the mounted condition as support walls for the elastically deformed ribs.

Abstract: A flexible ball type joint or bearing is constructed by inserting into a generally tubular-shaped rigid outer housing an assembly of an inner rigid member having a curved surface of part-spherical or barrel shape, a layer of elastomeric material surrounding said curved surface, and an annular member the inner surface of which is of a part-spherical or barrel shape to conform generally with said curved surface of the inner rigid member, and said annular member having an outer surface which conforms generally to the shape of the rigid outer housing.Subsequent to insertion of the assembly in the rigid outer housing, the rigid outer housing is adapted to possess a pair of end abutments between which the assembly is located. The outer housing is then subject to radial compression. The annular member is formed of a material of a modulus of elasticity which is higher than that of the elastomeric material and lower than that of the rigid outer housing.

Abstract: A ball joint at the end of a track rod of a steering system has a ball pin rotatable in a socket at the end of the track rod. The spherical head of the ball pin has an extension on which a slug is slidable. The slug is constrained to move in a direction axially of the track rod in an aperture in the base plug which closes the socket.

Abstract: An axial ball joint is fabricated from a housing having a substantially cylindrical outer surface and a cylindrical cavity which ends at an opening defined by a rim portion of the housing. The rim portion has a larger accumulation of material than elsewhere on the housing so that the housing can be deformed radially inwardly into a portion of the opening. A ball part with a ball portion and shank is inserted into the opening. A resilient socket is provided around the ball as a lining for the cavity. Once the ball portion is seated in the cavity, the rim portion is deformed inwardly toward the shank to retain the ball portion in the cavity. In this way the ball part is inserted from the opening end of the cavity rather than from an opposite end as is known in the art.

Abstract: A ball and socket joint, particularly a track rod joint for motor vehicles comprises a casing, a ball stud with a spherical head, and a socket received in the casing and being made of a material having a limited elasticity. At a flat polar surface of the spherical head, the socket is provided with an annular area which applies under biasing load against the flat polar surface and, upon an angular displacement of the ball stud, produces a restoring torque.

Abstract: The subject of the invention is a ball joint including a stud having a ball head located in a bearing shell made of elastic material. The bearing shell, which exerts a radial pressure on the ball head, is mounted in a joint housing having substantially a pot shape. The bearing shell is provided on its outer surface with elastically deformable elevations, lying against the inner wall of the joint housing. The elevations are arranged on the shell surface of the bearing shell and are formed as ribs and bars extending in the axial direction and arranged alternatively on the shell surface circumference. The bars are separated from the ribs by grooves. The bar width, measured in the circumferential direction, is greater than the width of the ribs. The radial extent of the ribs is greater than that of the bars. The bars thus bear against the joint housing only in the case of large loads acting on the joint.

Abstract: This invention is an improvement over the simple terminator, which has been applied at the mudline, and at the platform level, to resist very large stresses in the riser pipes when the vertically moored platform (VMP) is subjected to wind, tide and current. A second or short terminator is used with the terminator to form a multiterminator which results in the length and weight of the terminator assembly for a given site being greatly reduced from that of the prior art terminator. Thus, the cost of construction of the terminator assembly is drastically reduced with the use of our invention. Also disclosed is a novel bearing arrangement between the VMP and the terminator assembly.

Abstract: The invention provides a dismantleable ball and socket joint.A bearing made of a plastic material is placed in a rigid housing, and is adapted to receive a ball. Accessory component parts, or special shaping of the bearing provide elasticity to the bearing, which enables part of the bearing to change position relative to the housing, according to the direction of insertion or extraction of the ball. On assembly, the bearing contracts and expands.The assembly of the ball and socket joint requires a much smaller force than that required for extraction of the ball from the socket.

Abstract: A ball joint construction having a ball-stud member with a ball portion and a shank portion and an open-ended socket member into which the ball portion is inserted. An elastomeric covering is permanently bonded to both the ball member and a part of the shank portion to provide increased bond life and strength and then deformed for inserting in the open end of the socket thereby resiliently interconnecting the socket and ball members. An additional rib or lip of elastomer is provided on the covering of the ball adjacent the shank which collapses into a continuous multiple curved pattern during insertion into the socket. The rib provides for increased life of the elastomer by improved surface tension parameters and also keeps stones and other debris out of the open-ended portion of the socket. A further bonding between the socket and elastomer after insertion provides a completely bonded system capable of accepting very substantial angular movement without slippage or pullout.
