A trailing arm manufacturing method includes: preparing a metallic inner plate and a resinous plate member composed of at least two components; heat-crimping the inner plate while sandwiching the inner plate with the plate members in a state in which the inner plate is disposed between the plate members by using a pair of left and right molding dies including a rib molding portion for injection-molding a rib portion having a plurality of ribs; and injection-molding the rib portion on the plate member during the heat-crimping or after the heat-crimping.

A trailing arm which is connected to a vehicle body and a knuckle supporting a rear wheel includes: a pair of left and right resinous plate members having a hollow portion and a metallic inner plate which is joined to the left and right plate members in the hollow portion.

The invention relates to stabilizer bar (10) for use with the suspension of a vehicle such as a truck. The stabilizer bar (10) comprises a shaft (12) supported by bearings (18), cranked parts for example in the form of crank arms (30) being provided at or adjacent each end of the shaft (12), each cranked part having a connection point (32) for connection, in use, to a respective link member (34), wherein each connection point (32) is substantially aligned with a respective one of the bearings (18) relative to the axis of the shaft (12). The invention also relates to a vehicle incorporating such a stabilizer bar (10) and to a roll stabilization method using such a stabilizer bar (10).

A fiber-reinforced plastic chassis may include a steering element, where the steering element comprises at least one reinforcement structure formed with continuous fibers, where the steering element comprises at least one stiffening structure formed with short and/or long fibers, where the at least one reinforcement structure is formed integrally with the at least one stiffening structure via a thermosetting matrix material, and where the steering element comprises a plurality of bearing receivers integrated in at least one of the at least one reinforcement structure and the at least one stiffening structure for receiving bearing elements.

An axle strut for a vehicle having a shaft and two bearing regions. The axle strut has a supporting profile and two load-introducing elements. The supporting profile is formed from fiber reinforced plastics composite material. A first load-introducing element and a second load-introducing element are arranged at respective bearing region, and the supporting profile is arranged spatially between the two bearing regions. The supporting profile has a first connection area facing the first bearing region and a second connection area facing the second bearing region. Every load-introducing element has a receptacle. The supporting profile is connected by its first connection area and by the receptacle of the first load-introducing element to the first load-introducing element by an adhesive connection, and the supporting profile is connected by its second connection area and by the receptacle of the second load-introducing element to the second load-introducing element by a further adhesive connection.

A lightweight suspension upright or knuckle for a vehicle including a bearing connection interface arranged coaxial with the rolling bearing and including a first sleeve element and a second sleeve element arranged radially outside the first sleeve element and including a BMC/LFT/DLFT annular body that is sandwiched between a first and second shell elements, which are coupled together in a radially superimposed manner and which are preferably obtained in a semi-cured state as self-supporting elements, to be chemically and mechanically bonded together and with the BMC/LFT/DLFT annular body in a later stage during a step of forming a core (11) to fill either completely or partially an empty space (12) delimited between the first and second shell elements (8,9).

A multi-point link for a chassis of a motor vehicle. The multi-point link has at least one profile portion with two bearing areas arranged at opposite ends of the profile portion, the two bearing areas are connected to one another by the profile portion. An outer circumferential surface of the profile portion is provided with at least one stiffening element to increase the stiffness of the multi-point link, and the stiffening element is connected to the outer circumferential surface of the profile portion by material bonding.

A suspension system for a vehicle with a composite spring may include: a first longitudinally mounted spring 10 and a second longitudinally mounted spring 20 generating vertical stiffness of a vehicle; and a transversely mounted spring 30 generating roll stiffness and connected to the first and second longitudinally mounted springs. In particular, the transversely mounted spring 30 is connected to a vehicle body 1 by a support member 40. Stiffness of the vehicle may be further strengthened during a longitudinal behavior and a rolling behavior of the vehicle, and thus, running stability may be significantly enhanced.

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 leaf spring device for a suspension system for a vehicle according to the present disclosure may include a center leaf spring, side leaf springs respectively disposed at two opposite sides of the center leaf spring, and bracket modules each including a center bracket configured to accommodate an end of the center leaf spring, and a side bracket connected to the center bracket and configured to accommodate an end of the side leaf spring.
