A spheroidal joint for a tuned mass damper system includes a base having a concave seat and a lubricious liner secured thereto. The base defines a first mounting portion under the concave seat and a circumferential rim opposite the first mounting portion. The concave seat tapers radially outward to define a chamfer which terminates at a radially inner edge of the rim. The spheroidal joint includes an inner member that has a convex seat. The inner member has a second mounting portion extending from the convex seat and an indentation circumferentially extending around the inner member between the convex seat and the second mounting portion. The indentation cooperates with the chamfer for misalignment of the inner member relative to the base. The convex seat slidingly engages the lubricious liner.

A ball-and-socket joint as an engagement point for a driving element, having a ball head and a socket with a bearing opening, wherein the ball head has a pin for limiting the pivoting of the ball head in the bearing opening, wherein the ball head together with the pin is at least partially arranged in the bearing opening, and wherein at least one damping element is arranged in the bearing opening in such a manner that contact of the pin with the socket is prevented during the pivoting of the ball head.

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.

In a socket assembly having a housing with a closed end and an open end and an axially slidable and rotatable bearing, a spring washer seated on the axially slidable and rotatable bearing with a protrusion or a recess on the external periphery for engagement with a cooperating recess or protrusion on an inner cavity of the housing to effectively stop movement of spring washer with the axially slidable and rotatable bearing during driving conditions.

A double cardan constant velocity joint including a housing extending between a housing first end and a housing second end. A first yoke is pivotably coupled to the housing first end by a first spider. The first yoke extends between a first end having a socket and a second end configured for attachment to a first shaft. A second yoke is pivotably coupled to the housing second end by a second spider. The second yoke extends between a first end having a ball stud and a second end configured for attachment to a second shaft. A ball is disposed in the socket, wherein the ball has a recessed pocket for receipt of the ball stud. A biasing member is disposed in the recessed pocket to impart a bias on the ball, wherein pivotal movement of the first yoke and the second yoke causes the ball to translate in the socket.

A universal joint is provided, including: a seat, including a receiving room extending in an axial direction and at least one through hole in communication with the receiving room; a connecting member, including a ball head rotatably received within the receiving room; and an assembling mechanism, including at least one blocking member and a sleeve member sleeved around the seat, the at least one blocking member being received within the at least one through hole and blockable with the ball head in the axial direction, the sleeve member covering the at least one through hole; wherein the seat has a first hardness, the sleeve member has a second hardness smaller than the first hardness, an outer circumferential wall of the seat is partially embedded within an inner circumferential wall of the sleeve member.
