A collar includes a tubular portion and a flange portion extending radially outward from an end portion of the tubular portion, first and second corner portions formed by the tubular portion and the flange portion are provided with first and second curved surface portions formed as concave curved surfaces, an end portion of the trailing arm is provided with a collar through-hole into which the collar is inserted, and an edge portion of the collar through-hole is provided with a through-hole side curved surface portion formed as a convex curved surface coming into contact with the first and second curved surface portions.

A terminal sealed portion is formed on an end portion of a hollow rod made of steel. An enclosed space is formed on an inner side of the hollow rod. At an end of the enclosed space, a terminal gap is formed. A volatile powdered rust inhibitor is supplied in the enclosed space. As the volatile powdered rust inhibitor is vaporized, the enclosed space is turned into a rust-inhibiting atmosphere. As the vaporized component of the volatile powdered rust inhibitor is adsorbed to an inner surface of the enclosed space, an inner surface rust-inhibiting film is formed. The vaporized component also enters inside the terminal gap, and forms a terminal rust-inhibiting film.

An insert to a mold for a leaf spring comprises a substrate and a hole that extends through the substrate, A post protrudes from the substrate such that the insert, may be coupled to the mold. Further, the post covers the hole on a first end, so the hole is not exposed. On the other end of the hole, a thin overlay that covers the hole. Thus, during a process where resin is added to the mold, no resin enters the hole. The insert, when added to a leaf spring, offers reinforcement on areas where there is high stress. Therefore, holes may be added to a leaf spring at areas of high stress without overly weakening the leaf spring.

A four-point link for a vehicle includes a core element and a main laminate comprising a fiber reinforced plastics composite material, which wraps around the core element. The core element comprises four load-introducing elements and a foam core, and the four load-introducing elements (4) are connected by positive engagement to the foam core (5). The four-point link has four additional windings, wherein a respective additional winding wraps around a first, second, third and fourth load-introducing element and operatively connects a respective one of the latter to the main laminate. Compressive forces can be introduced into the main laminate (3) by means of every additional winding (6).

A bearing eye for a leaf spring for sprung support of a vehicle component on a vehicle body of a vehicle may include a through opening and a torsion spring therein, and a first catch. The bearing eye may provide pivotable mounting of the leaf spring on the vehicle body. The torsion spring is twistable relative to the bearing eye and connectable non-rotatably to the vehicle body. The first catch may project radially inwardly into the through opening, and the torsion spring has a second catch that projects radially outwardly into the through opening. The first and second catches may form a locking engagement which, depending on a degree of relative twisting between the bearing eye and the torsion spring, stops the relative twisting.

Provided is a vehicle suspension member securing a strength against external force in a vehicle longitudinal direction. A lower arm includes an arm body, a front bush support part, a rear bush support part, a ball joint support part, a first rib, a second rib, and a third rib. The third rib is disposed in a lateral part connecting the ball joint support part to the rear bush support part. An S-shaped rib center curve of the third rib intersects with a straight line at an intersection. |(1−S2/S1)|≤0.2 is satisfied, where S1 is area of a first region defined by the rib center curve and the first straight line, and S2 is area of a second region.

A method for producing a connection element (1, 30), in particular for an articulated connection of components arranged in a chassis. The connection element (1, 30) is formed by a profile element (6, 31) which includes a joint portion (2), for accommodating a joint component (5), a central portion (4), and a connection portion (3). The profile element (6, 31) is formed by an arrangement of at least one first profile section (7, 32) and at least one second profile section (8, 33), which are held in position, with interlock, by at least one fixing element (9, 10), a joint component (5) is inserted, into the joint portion (2) so formed, and the profile element (6, 31) and the joint component (5) are partially overmolded with a plastic material.

A wheel suspension link including a structure connection location for connecting the link to a vehicle structure and a wheel carrier connection location connecting the link to a wheel carrier. The structure connection location and wheel carrier connection location arranged on a link member extending along a link plane. The link member including a base member formed in a materially integral manner from a discontinuously reinforced plastic material. The link member including a reinforcement, containing continuous fibers, connected to the reinforced plastic material. In one embodiment, the reinforcement limited with respect to the link plane to a first region of the link member while the base member extends into a second region.

A four-point link (1) for a wheel suspension of a vehicle, having a core element (2), a thread (3) and four bushings (6). The thread (3) is pre-impregnated with a resin. The core element (2) has a torsional element (4) and four supporting arms (5) integrally connected to the torsional element (4). A bushing (6) is arranged, on each respective distal end of the supporting arms (5), for holding a respective bearing element. The core element (2) and the respective bushings (6) are at least partially wrapped with the thread (3) in order to connect the bushing (6), in each case, to the thread (3) at least in a non-positive manner. In addition, a method for producing the above-mentioned four-point link (1).

Wishbone-style control arm assemblies for a vehicle and methods for assembling the same are disclosed. A control arm assembly includes a first elongated segment having a first connection feature at one end of the first segment. The control arm assembly includes a second elongated segment having a second connection feature at one end of the second segment. Opposite longitudinal ends of the first and second segments may include third and fourth connection features, respectively, that are configured to interface with the vehicle. The first and second connection features are aligned to form an aperture that extends at least partially through the first and segment connection features, through which a bushing is press-fit and then swaged to form a strong connection that reduces or eliminates the need for mechanical fasteners or adhesive bonds. The bushing connection independently enables the control arm to maintain a secure connection between segments during operation of the control arm when assembled in the vehicle.
