A joint for connecting an attachment to a hydraulic ram comprises a ball and a socket. The socket connected to the base top surface of the attachment and encompassing at least a portion of the ball. The ball may be connected to a stem which may comprise a hole which serves as a connection point between the joint and an end of a hydraulic ram.

A ball head includes: a main body provided with ball body and fastener accommodating portions adjacent to each other in an up-and-down direction; a ball body provided with a threaded rod extending outward therefrom; and a fastener. The ball body and fastener accommodating portions are respectively formed with openings respectively extending upward and downward and having diameters respectively smaller than the diameters thereof, and communicated with an external space through a notch of the main body, wherein a fixing assembly is disposed at the notch. The notch can be expanded, such that the fastener and the ball body are respectively placed into the fastener and ball body accommodating portions. The notch can be further contracted by locking the fixing assembly tight and thus the ball body is non-rotatable, while the notch can also be expanded by loosening the fixing assembly and thus the ball body is rotatable.

The assembly includes a housing that has an inner bore and a ball stud that has a ball portion with opposing first and second hemispheres. A bearing assembly is disposed in the inner bore of the housing and presents a curved first bearing surface that is in slidable contact with only the first hemisphere of the ball portion. The ball socket assembly also includes a curved second bearing surface that is presented on a different component from the bearing assembly and is in slidable contact with the second hemisphere of the ball portion. The bearing assembly has a plastic portion and a plurality of metal segments. The metal segments collectively define the first bearing surface and are fixedly attached with the plastic portion. The plastic portion allows the metal segments to individually move relative to one another to seat against the ball portion of the ball stud.

A ball joint includes a cover plate with a nested portion along an outer perimeter having a nested portion thickness, a domed portion located radially inward of the outer perimeter having a domed portion thickness, and a pressed portion located between the nested portion and the domed portion having a pressed portion thickness. The pressed portion thickness is less than the domed portion thickness, which during manufacture, is formed when the cover plate and bearing are simultaneously pressed into their final form and position. A tool can be used to press the cover plate and bearing in a single operation. The tool can have interchangeable components, allowing for the manufacture of differently sized ball joints.

A torque transmitting ball joint can include a spherical ball, a stem extending from the spherical ball, one or more pins coupled to the spherical ball, and a socket. The socket can define an opening sized to contain the spherical ball within the socket and one or more slots sized to accommodate a pin of the one or more pins. The one or more pins can be contained by the one or more slots and can translate within the slot as the spherical ball rotates relative to the socket about a pivot center. At least one of the one or more pins can abut a sidewall of its slot and transmit torque from the stem to the socket via the spherical ball when the stem and spherical ball rotates relative to the socket.

A sealing bellows made of an elastomeric material includes: a first end face; a second end face; and a casing having a central axis, the casing being arranged in an axial direction between the first and second end faces, the casing including at least one torsion-compensating element for absorbing torsional movements introduced into the sealing bellows substantially without torsional stress. The first end face includes a first static seal and the second end face includes a second static seal. The sealing bellows is made of a TPE material.

A spherical joint of the present disclosure includes a ball member and a socket having an inner circumferential surface configured to spherically contact the ball member. The socket includes a cage part forming the inner circumferential surface and having an opening, and a bar-shaped connecting part provided to the cage part. A fastening member is disposed at the cage part so as to reduce a space of the opening in the extending direction of the connecting part and such that a gap is formed between the fastening member and the ball member. The opening is formed in a part of the inner circumferential surface other than a part where the largest load is applied.

A ball joint (10) capable of stabilizing sliding torque while suppressing cost increase is provided. The ball joint (10) includes a first lubricant (G1) interposed between a ball part (40) of a ball stud (14) and a bearing sheet (13). The ball joint (10) includes a second lubricant (G2) having a higher friction coefficient than the first lubricant (G1) and enclosed inside a dust cover (15).

A ball joint press for installation/removal of ball joints or bushings into/from suspension components of vehicles. In general, the press includes first and second frame portions, a spine/shaft coupling the first and second frame portions together, and actuators coupled to one of the first and second frame portions. The actuators are sized and spaced such that combined forces of the actuators minimize a bending moment (and bending stress) about the shaft. The actuators may also share a feed line that provides for equal pressure across both actuators. This reduces an axis of bending of the shaft, and causes the first and second frame portions to remain substantially parallel and the force in line with an axis of motion to install or remove the ball joint.
