| 20100124455 | REVOLUTE JOINT WITH INTEGRATED RADIAL COMPLIANCE - A pivot joint assembly includes a housing having a bore therethrough and a coaxial central axis. A stud is disposed coaxially with the bore, and has a bearing surface. A resilient member disposed between the housing and the stud is biased against the housing to accommodate radial loads transferred therebetween. An inner metal ring disposed between the resilient member and the bearing surface substantially surrounds the bearing surface and is sized for a sliding fit between the bearing surface and an interface surface of the inner metal ring. The stud is configured to pivot about the central axis by a range of at least 40 degrees. The pivot joint assembly may further include a sealing element configured to seal the bearing surface and the interface surface. Another embodiment includes an axial restraint element configured to prevent axial separation of the stud and housing. | 05-20-2010 |

| 20120155952 | METHOD FOR MANUFACTURING A BEARING SHELL ASSEMBLY AND BEARING SHELL ASSEMBLY FOR A BALL JOINT - A method for manufacturing a bearing shell assembly for a ball joint includes the following steps: a) a bearing shell having a plastic extension is produced; b) a spring element is arranged in a region of the plastic extension; and c) the spring element is fastened to the bearing shell by deformation of the plastic extension. The invention further relates to a bearing shell assembly for a ball joint, including a bearing shell and a spring element, the spring element being non-detachably connected with the bearing shell. | 06-21-2012 |
| 20120301214 | Ball Joint - The invention relates to a ball joint which comprises a joint housing, a bearing shell received in the joint housing, and a ball stud having a ball head arranged for pivoting movement in the bearing shell. The ball head is prestressed by a spring system substantially in the direction of a longitudinal axis of the ball stud against the joint housing. The spring system is composed of spring elements connected in parallel and/or in series, at least one spring element of the spring system being made of a polymer material or of an elastomer material. | 11-29-2012 |
| 20130121756 | BALL JOINT FOR AUTOMOTIVE SUSPENSION - A ball joint comprising: a housing having an inner cavity defined inward of a seat end, a side wall and a closure end having an opening, an edge about the opening in an assembly position extending upwardly; a ball stud having: a lower ball end with an outer convex spherical surface, a middle portion, and a connector end; a first bearing, slidably housed within the cavity, having an inner concave spherical surface; a retention plate, housed within the cavity inward of the edge about the opening, wherein the edge of the opening extends inwardly engaging an outer surface of the retention plate in a closed position; and a first disc spring disposed in a disc annular recess in at least one of: an outer surface of the first bearing; and an inner surface of the retention plate. | 05-16-2013 |
| 20140205366 | BALL JOINT FOR AUTOMOTIVE SUSPENSION - A ball joint comprising: a housing having an inner cavity defined inward of a seat end, a side wall and a closure end having an opening, an edge about the opening in an assembly position extending upwardly; a ball stud having: a lower ball end with an outer convex spherical surface, a middle portion, and a connector end; a first bearing, slidably housed within the cavity, having an inner concave spherical surface; a retention plate, housed within the cavity inward of the edge about the opening, wherein the edge of the opening extends inwardly engaging an outer surface of the retention plate in a closed position; a first disc annular recess disposed in: an outward surface of the first bearing; an inward surface of the retention plate; or an inward surface of the seat end of the housing, and a first disc spring disposed in the first disc annular recess, the first disc annular recess laterally restraining: an outer circular edge of the first disc spring; or an inner circular edge of the first disc spring, during compression of the first disc spring, and a peripheral annular shoulder adjacent the first disc annular recess axially limiting axial movement, thereby limiting compression of the first disc spring. | 07-24-2014 |
| 20140301772 | BALL JOINT - A ball joint includes a ball member, a socket member, and a resilient pressing mechanism. The ball member couples with the socket member. The resilient pressing mechanism is positioned between the ball member and the socket member, applying compression to cause the ball member to tightly contact the socket member. The resilient pressing mechanism includes a plurality of springs positioned in parallel between the ball member and the socket member. | 10-09-2014 |
| 20150337891 | LINKAGE WITH SPHERICAL OR JOURNAL BEARING ASSEMBLY - An assembly includes a spherical bearing race and a spherical bearing element. The bearing race includes a race first segment, a race second segment and a bore that extends along an axis into the bearing race. The bore also extends radially within the bearing race between the first segment and the second segment. The bearing element is arranged within the bore, and radially engages the first segment and the second segment. | 11-26-2015 |
| 20150337892 | BALL JOINT - A ball joint, in particular, an axial joint, having a ball stud, which is enclosed in a ball socket. The ball socket is enclosed in a joint housing and is integrally formed having at least one spring element in a region of the ball socket that faces away from the opening of the joint housing. The spring element has discontinuities, in particular in the form of slots, so that wear compensation is created by the spring element within the ball joint. | 11-26-2015 |
| 20160138646 | Ball Joint Connection - A ball joint connection with a ball socket in which a ball segment-shaped opening is formed, and a joint ball is rotatably supported and snap-fitted in the ball socket. The joint ball shall be inserted in a ball socked with little effort, but can be removed only with a major effort or not at all in a nondestructive manner. To this end, below the opening, at least one rigid tab is fastened in the ball socket which, in a rest position, extends so far in the direction of the opening that it has a predetermined distance to the mounted joint ball. The tab is spring-elastically movable from the rest position during the assembly of the joint ball. | 05-19-2016 |
| 20160186966 | MOVABLE BALL-SHAPE CONNECTOR FOR LIGHTING FIXTURE - A movable ball-shape connector for a lighting fixture includes a movable rod, a spherical body, a fix cup, a press block, a spring, and an adjusting block. The spring is disposed between the spherical body and the adjusting block, to produce an elastic force acting upward. And that is used to produce the force to press the spherical body to stay between the movable rod and the fix cup, to fix the spherical body to a certain angle after rotation. Meanwhile, the adjusting block can be rotated, to make it move upward or downward, to adjust the force of the spring pressing against the spherical body, in achieving the objective of fixing the spherical body to a certain angle after rotation. | 06-30-2016 |
