A ball joint is disclosed containing a body of a joint, where there is inserted a pin having a longitudinal axis and including a first threaded end and a second spherical end which is rotatably arranged within a seat of the body and able to co-operate with a first spherical-cap-shaped element or shell inserted within a seat having a corresponding shape of a second spherical-cap-shaped element or shell cooperating with a covering element so as to close the spherical end of the pin within the body. The second spherical end of the pin and the first and second shells including pairs of recesses and ridges in the contact areas are suitable for reciprocally compenetrating, with the pairs of recesses and ridges being arranged at 90° to each other to allow the rotation of the pin along all axes in the space (X, Y, Z). An angular movement sensor integral with the body of the joint is provided, for co-operating with the second element or shell to detect the rotation of the pin around the axis containing the longitudinal axis of the pin.

VEHICLE SUSPENSION SYSTEM

A vehicle suspension system smoothly changes a vehicle posture with respect to a steering force and a steering angle by minimizing a kinematic roll at an initial turning stage, thereby allowing a driver to obtain the sensation of maneuvering the vehicle well. The suspension system includes a front suspension having geometry satisfying that a caster angle is +3° to +5°, a caster trail is +20 to +30 mm, an intersection point between a kingpin axis and ground is located on an inner side in a vehicle width direction of a center of a tire contact patch, and an anhedral angle of a lower arm is +2.8° to +7.2°. Arear suspension includes five links and has geometry satisfying that a virtual kingpin axis extends near the center of a tire contact patch of a rear wheel assembly and extends vertically at −2° to 0°.

A ball joint comprises: a ball stud which includes a stud part on one end side connected to a structure and a ball part on the other end side; a housing which oscillatably and rotatably supports the ball part of the ball stud; and a ball sheet disposed between the housing and the ball part. The ball sheet includes a recessed/protruding part formed of at least one of a recessed portion and a protruding portion on a surface facing the housing. The housing includes a fitting part having at least one of a protruding shape and a recessed shape each of which fits to the recessed/protruding part.

A BUSH PIN, A BRACKET AND A MOUNTING ASSEMBLY FOR A V-STAY FOR A VEHICLE

A bush pin is provided for a V-stay presenting two arms adapted to structurally connect an axle casing for a vehicle wheel axle to a respective of a left and right vehicle frame member, including a central bush portion and a fastening portion on each side of the central bush portion, wherein each of the fastening portions is adapted to be connected to a bracket by a fastening arrangement, wherein the bush pin includes a first contact surface on each side of the central bush portion, and displaced from the fastening portions, for contacting a corresponding contact surface of the bracket in order to transfer loads.

THREE-POINT LINK
20230003250 · 2023-01-05 ·

A three-point link having two control amis forming an acute angle and meet at a central joint. The central joint has a cylindrical dome extending perpendicular to a plane defined by the control amis. The central joint has a joint ball penetrated by the dome. To prevent separation of the central joint, it has a captive securing device which functions as a stop that extends perpendicular to an axial direction. The securing device is penetrated by the dome and is secured against axial withdrawal by an annular securing clement. Viewed in axial direction, the annular securing element is arranged on a side of the captive securing device) remote of the joint ball and engages in a circumferential groove of the dome. The annular securing element is snugly surrounded in radial direction by the captive securing device to prevent a withdrawal of the annular securing element from the circumferential groove.

Joint, link for a wheel suspension and method for assembling a joint

A joint (10) with first and second joint components (12, 26; 19) are movably connected to one another. The first joint component (12, 26) has a spherical joint body (14, 28) and the second joint component (19) rotatably and pivotably holds the joint body (14, 28). A sensor device, for determining the position of the first and second joint components (12, 26; 19) relative to one another, is arranged on the joint (10). The sensor device has at least one sensor element (21, 31) which can be integrated in a housing (18) that is produced by an assembly overmolding process. The joint housing (18) forms the second joint component (19) in which the joint body (14, 28) is directly supported.

Sealing apparatus for sealing the ball joint of a kingpin

The invention relates to a sealing apparatus for sealing the ball joint of a kingpin comprising at least one holding ring and at least one seal ring, wherein the seal ring is provided at least partially within a groove of the holding ring, and wherein the groove is provided in a radially inwardly disposed region of the holding ring.

Rod-end front suspension
11697457 · 2023-07-11 ·

A rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint.
