Abstract: The subject of the invention is a tie rod joint for motor vehicles for the linking of the inner ends of two tie rods to a steering rod, actuated by a steering gear, the inner ends of the tie rods being shaped as formed joint parts, which project in each case between an outer and an inner bearing part, while between the joint parts and the outer bearing part on the one hand, and the inner bearing part on the other, inlays are arranged, and while the outer bearing part, the joint parts, the inlays and the inner bearing part are prestressed by at least one tension bolt fastened to the steering rod.

Abstract: In fastening a sealing bellows to the housing of a ball joint, the sealing bellows has a doughnut-form rim which seats in a circumferential ring groove, open in the axial direction and designed U-shaped in cross section, on the outer rim of the housing. The ring groove is formed in part by a circumferential recess, L-shaped in cross section, on the housing rim, and by an L-shaped holding ring, opposite in cross section to the recess and fastened into this latter. To simplify this fastening and to protect the fixing of the sealing bellows, the flat bottom of the opening has a circumferential ring step lying radially inward, and the fastening of the holding ring by its ring flange to the ring step against the radially extending surface of the recess, is made by means of a circumferential projection or several segment-like projections staked from the ring step.

Abstract: The subject of the invention is a ball joint for motor vehicles, with two substantially hemispherical bearing shells (4, 5), set between a joint housing (1) and a ball head (3), of which the inner has on its outer side several ridges (8) for support in the joint housing (1). To simplify the mounting of the ball joint and to produce flat lubricant pockets (9) on the inner side of the inner bearing shell (4), it is proposed that the wall thickness (S1) of the inner bearing shell (4), designed in one piece, be greater, in the zone of the ridges (8) than the gap width between the joint housing (1) and the ball head (3), and that the wall thickness (S2), in the zone between the ridges (8), be equal to or less than half the wall thickness (S1) in the zone of the ridges (8), the inner bearing shell (4) being made of a soft-elastic plastic and the outer bearing shell (5 ) being made of a hard-elastic plastic.

Abstract: The subject of the invention is a ball joint for motor vehicles comprising a bearing insert (4) located between a joint housing (1) and a ball head (3). The bearing insert is provided with meridionally extending slots (9) arranged in a half-portion gripping of the ball head over the equator. A clamping ring (5) located in the housing grips the tongues (10) of this bearing insert (4). To improve the elasticity of the bearing parts while retaining a good distribution of lubricant, the clamping ring (5) is provided with circumferential grooves (13) on its inner surface and with openings (15) in the outer end surface (14).

Abstract: A ball joint for connecting rod parts having a ball socket (1) of flexible plastic at the end of a shaft (2) in order to receive a ball head (4). In order to facilitate the assembling of the ball joint while retaining the customary pulling-out forces, it is proposed that a wall section of the ball socket (1) be developed as a yoke-shaped part (5, 12) developed in one piece thereon, which can be engaged together with the ball head (4) into the ball socket (1).

Abstract: The subject of the invention is the fastening of a sealing bellows to the joint housing of a ball joint, in which the housing-side rim of the sealing bellows is laid firmly into a ring groove circumscribing the joint housing, designed substantially U-shaped in cross section, the bellows rim having a profiling adapted to the U-shape of the ring above and being pressed into the ring groove by a clamp ring. To increase the sealing effect, it is proposed that the profiled zone of the bellows rim lying opposite the bottom of the ring groove forms, when drawn on by the tension ring, a fold lifting off from the bottom of the groove, arched upward, which stretches under the pressure of the clamp ring to force the bellows rim against the side walls of the groove.

Abstract: An injection mold for the manufacture of sealing elements consisting of elastic material and having undercuts, particularly sealing bellows for joints, for example ball joints in automotive vehicles, includes followers which are divided centrally in the longitudinal direction of the sealing element and form the outer contour. The mold has a core plunger which forms the inner contour and is divided into an upper core plunger part and a lower core plunger part which are movable relative to each other. The sealing element is removed from the foregoing parts after the opening of the followers. In order to be able to remove the sealing element automatically form the mold without the use of parting agent the followers are split in transverse direction into an upper and a lower pair of followers in the region between the inner undercut of smallest diameter and the outer undercut of smallest diameter.

Abstract: A ball-joint has a hollow housing, and a ball in contact with a socket in the housing; and a locking device is disposed between the largest diameter of the ball and the device which supports the locking device, so that the ball is restrained from moving off the ball socket when the pin shaft is pulled in the direction away from the ball socket. A plurality of locking rings is produced by fabricating a resiliently deformable longitudinal rod, forming the rod into a helix, and cutting the helix parallel to the longitudinal axis.

Abstract: A ball-joint includes a housing with an inwardly facing projection, a ball socket secured to the housing near an end thereof, and a ball pin engaged in the ball socket. A portion of the ball socket extends towards the ball, so as to at least partially surround the ball, and has a plurality of slots extending in a meridional direction towards the free end of the ball socket, so as to form tongues between the slots. The ball socket has an external groove in a portion thereof extending in a direction away from the ball, which engages the projection of the housing, so that the ball pin may be inserted into the ball socket by elastically deforming the tongues, and subsequently the ball socket may be slid into the housing.

Abstract: A ball joint includes one member having a socket portion which has an internal support surface bounding a cavity, and another member having a mounting portion which is received in the cavity, and has a spherical contact surface that contacts the support surface, and thus mounts the two members for relative pivotal movement about at least two axes. The movement about one of the axes is made easier than about the other axis by providing the support surface with at least one zone which has a center located on the one axis, and which so engages the contact surface as to oppose the relative movement of the members with a higher frictional force per unit area, than the remainder of the support surface.

Abstract: In a coupling including a ball, a hollow housing, and a slit which extends in correspondence with preselected longitudinal lines on the ball within a predetermined region of the hollow housing so that a series of resiliently movable tongues are provided between the slits. The housing and its tongues are adapted to surround the ball and to resiliently engage portions of the ball respectively, so that a general axial pressure exerted on the housing varies the intensity of engagement of the ball portions by the tongues.
