A four-point link for a wheel suspension of a vehicle includes a core element, a filament and four bushings. The filament is pre-impregnated with a resin. The core element further has a torsional element and four support arms connected integral with the torsional element. The core element and the respective bushing are at least partially wrapped by the filament. The respective bushing for receiving a respective bearing element is arranged at a respective distal end of the respective support arm. The respective bushing has at least one anchor element, and at least one undercut is formed between the at least one anchor element and the bushing, and the core element engages in the undercut for connecting the bushing to the support arm of the core element by positive engagement.

A suspension strut fork that has an upper portion which is constructed in an integral, materially uniform manner in the form of a suspension strut receiving member. Members and fork arms protrude therefrom in an integral, materially uniform manner. A gap is provided between the members. Via this gap, the members can be moved toward each other so that a resilient and/or damper element which is arranged in the suspension strut receiving member is securely clamped.

A method for producing motor vehicle controls from extruded profiles and a motor vehicle control. A length section of an extruded profile strand is provided and this is either processed by cutting technology and divided into several extrusion profiles or is first divided into several extruded profiles and they are then processed via shear cutting. By means of a mechanical processing of the extrusion profiles, the motor vehicle controls are formed. The length section has a double T-shaped cross-section with a brace and two belts aligned perpendicular to the brace, wherein the end-side of the belts are connected to flanges. During manufacturing, a motor vehicle control is produced with a steering element, which comprises a middle part and two side arms. In the middle part as well as in the side arms, bearing housings are configured.

An elastic member is an elastic member formed of a wire having a cross section that is substantially circular, the cross section being orthogonal to a longitudinal direction, and the elastic member being expandable and contractible in a predetermined direction; and including: a first alloy portion that is made of an aluminum alloy having a tensile strength larger than 950 MPa and equal to or less than 1100 MPa at room temperature; and a second alloy portion configured to cover the first alloy portion, the second alloy portion having a thickness in a radial direction smaller than a radius of the first alloy portion, and being made of an aluminum alloy having a tensile strength of 100 MPa to 650 MPa at room temperature.

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.

Provided is a production method of an aluminum alloy forging for an automobile suspension having a disturbance affectable surface with not excessively notch-sensitive. The production method includes, as heat treatment processes, a solution heat treatment process, a quenching process, and an artificial age hardening process. The quenching process is performed by bringing a lower surface of the aluminum forging to be disposed on a ground side when assembled to the automobile into contact with water before an upper surface of the aluminum forging opposite to the lower surface is brought into contact with the water.

A vehicular hybrid suspension arm includes a suspension arm body made of a steel material, and an insert molding inserted into and coupled to the suspension arm body, providing a suspension arm having reduced weight and high rigidity.

A damper assembly for a vehicle which includes a damper body, a first ring element, and a spring coupler. The damper body includes a threaded portion which extends between a first end and a second end of the damper body. The first ring element is disposed within a first groove in the threaded portion. The spring coupler having a passage to concentrically receive the damper body such that the spring coupler is configured to slide over the first ring element. The first ring element is disposed within the first groove of the threaded portion such that a sliding clearance is provided between an inner portion of the spring coupler and the threaded portion.

Disclosed herein are active hydraulic cylinders for use in active vehicle suspension systems, and methods for assembling active hydraulic cylinders for use in an active vehicle suspension system. In particular, in certain embodiments a manifold may encircle a portion of an outer tube of a twin tube assembly. The manifold may mechanically and fluidly couple a pump assembly to the twin tube assembly. In certain embodiments, the manifold may be welded onto the outer tube.
