A multi-degree-of-freedom support mechanism includes a first member having a protruding part with a spherical surface, and a second member having a pair of planes opposite to each other across the protruding part. One of the first member and the second member is able to make relative movement with respect to the other with sliding movement of the spherical surface on the pair of planes. The pair of planes is in contact with the spherical surface. The relative movement includes translational movement in two degrees of freedom in planar direction and rotational movement about an axis in three degrees of freedom in the pair of planes.

A ball joint assembly for use in a vehicle suspension system includes a housing including a first end surface and an opposing second end surface. The housing at least one of includes an outer tie rod of a steering assembly and is configured to be coupled to the outer tie rod of the steering assembly. The housing defines a cavity and also includes an opening defined in the second end surface. The ball joint assembly also includes a ball stud coupled to the housing such that a first portion of the ball stud is positioned in the cavity and a second portion of the ball stud extends through the opening. A wire harness is coupled to the first end surface of the housing and extends away from the housing in a direction opposite the second end face surface.

A dust cover is provided that is attached to a ball joint in which a spherical portion in a stud having the spherical portion and a shaft is accommodated in a socket and a knuckle is fastened into the shaft and is provided with a large diameter opening fixed to the outer peripheral surface of the socket, a small diameter opening attached to the shaft part of the stud, and a film portion connecting the large diameter opening and the small diameter opening. The small diameter opening is provided with a seal portion in close contact with the outer peripheral surface of the shaft and a contact portion in close contact with the knuckle. In the contact portion, a foreign matter discharge groove discharging external foreign matter which tends to accumulate on the small diameter opening to the outside are formed.

The socket assembly includes a housing with an inner bore that extends from a wall at a closed end to an open end. A ball stud is received in the inner bore, and a shank portion of the ball stud projects out through the open end. A backing bearing is movably disposed in the inner bore. The backing bearing presents a bearing surface which is in sliding contact with a ball portion of the ball stud. An exit bearing is locked into a fixed position within the inner bore and has another bearing surface which is in sliding contact with the ball portion. A spring is positioned between the wall and the backing bearing and imparts a preload force against the backing bearing. The wall is deformed to preload the spring against the backing bearing and reduce clearances between components in the socket assembly.

A rotary joint includes an inner joint element which has a spherically shaped inner convex joint face and an inner joint connection head protruding from the inner convex joint face; an outer joint element which has a spherically shaped inner concave joint face, a spherically shaped outer convex joint face and an outer joint connection head protruding from the outer convex joint face, wherein the inner joint element is held within the outer joint element such that the two joint elements can be rotated with respect to one another along the inner joint faces; and a joint bearing which has a spherically shaped outer concave joint face, wherein the outer joint element is held within the joint bearing such that the outer joint element can be rotated in the joint bearing along the outer joint faces.

A mechanical component for a vehicle, having a measurement region with a surface, and at least one force sensor associated with the measurement region for detecting a force to which the component is exposed. The component (3) has, disposed in the measurement region, a hollow body (3b) with a cavity (4) in which the at least one force sensor (7) can be positioned.

This ball joint is provided with: a ball stud, one end being fastened to a suspension device/stabilizer, and the other end having a ball part; a housing that rotatably supports the ball part of the ball stud; and a ball seat provided so as to be interposed between the housing and the ball part, the ball seat having an inner spherical part for accommodating the ball part. The ball seat is provided to the housing by insert injection molding. The inside diameter dimension of the inner spherical part formed by separate injection molding is set to a dimension corresponding to the anticipated amount of molding shrinkage of the resin during the insert injection molding.

A dust cover for a ball joint includes a seal structure on a small-diameter opening section that prevents dust lip lift off during compression. The seal structure includes a seal lip and a dust lip that elastically abut against a seal surface located between a knuckle and a stud of the ball joint. The dust lip has an axial length in contact with a sloping part of the seal surface of 0.5 mm to 1.0 mm. Further, a tip of the dust lip is axially spaced apart from a tip of the seal lip by 0.5 mm to 1.2 mm.

A link arm member of the present invention is used in a vehicle for connecting a suspension and a stabilizer, and includes: a support bar that is sealed by plastically deforming a hollow metal pipe at both ends thereof; and a housing part made of resin that is arranged at each end of the support bar and has a receiving hole for receiving a ball part of a ball stud to which the suspension or the stabilizer is fixed, wherein the housing part is formed by insert molding with the support bar.

Some embodiments are directed to a suspension assembly of a vehicle having a frame and an engine. The suspension assembly can include a trailing arm having first and second ends and configured to extend from the frame at the first end. The suspension assembly can further include a knuckle connected to the second end of the trailing arm. The suspension assembly can include an arm assembly configured to extend from the frame to support the knuckle and facilitate translational movement of the knuckle relative to the frame in at least one predetermined direction. The suspension assembly can include a damper and a connecting link configured to extend from the frame and connected to the trailing arm. The suspension assembly can include a stabilizer bar connected to the connecting link and extending rearward around the engine.
