A suspension actuator includes a first housing part, a second housing part, a ball screw actuator that is connected to the first housing part and to the second housing part, and an air spring membrane that is connected to the first housing part and to the second housing part. The air spring membrane includes a flexible material and a reinforcing structure that is disposed within the flexible material to resist torsion loads that are applied to the second housing part by the ball screw actuator.

A jounce bumper of an automotive vehicle suspension system contains a longitudinal axis. The jounce bumper is configured to resiliently deform between an uncompressed state and a compressed state, where in the compressed state the jounce bumper has a smaller length in the direction of the longitudinal axis than in the uncompressed state. The jounce bumper also contains a base body that acts as a primary spring element, where the base body is partially or completely made of a volume-compressible first material. In particular, the base body further contains at least one secondary spring element integrated within the base body. The secondary spring element is resiliently deformable between a first length in the uncompressed state and a second length in the compressed state, where the second length is smaller than the first length. The secondary spring element is partially or completely made of a compact second material.

A hub bearing module for a lightweight suspension upright or knuckle of a vehicle, the hub bearing module including a wheel bearing and a bearing connection interface to the suspension upright or knuckle, the bearing connection interface being 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 composite, preferably BMC (Bulk Molding Compound) annular body having a radially inner lateral surface mechanically coupled to the first sleeve element and a radially outer lateral surface configured to mechanically and chemically couple with the suspension upright or knuckle.

A bearing structure component for a vehicle bearing, having at least one through-opening for receiving a connecting element or a bearing which is made of foamed synthetic material, and the foamed synthetic material forms an integral foam structure. In an embodiment, at least one first local section of the integral foam structure has a wall thickness of greater than 4 mm.

A suspension arm includes a ball stud including a spherical ball; a bearing in which the ball is accommodated; a housing having an inner peripheral portion, an outer peripheral portion, and a lower end portion that connects a lower end of the inner peripheral portion and a lower end of the outer peripheral portion, and configured to accommodate the ball and the bearing in a state in which the ball and the bearing are spaced apart from the inner peripheral portion; an arm body coupled to a portion of the outer peripheral portion of the housing; and an insert molding part formed on an outer peripheral portion of the bearing, the inner peripheral portion of the housing, and the lower end portion of the housing to couple the bearing with the housing. A convex-concave portion is formed on the inner peripheral portion of the housing along a circumferential direction.

A three-point suspension link for a chassis of a vehicle has two arms and a central bearing area. Each arm has a bearing area. The three-point suspension link comprises two load-introducing elements, a central load-introducing element, a stabilization layer, a core element and a supporting winding. The stabilization layer and the supporting winding are formed from a fiber reinforced plastic composite material. A load-introducing element is arranged at every bearing area. The central load-introducing element is arranged at the central bearing area. The core element is surrounded by the stabilization layer in a subarea. The supporting winding surrounds the load-introducing elements, the central load-introducing element, the stabilization layer and the core element in a subarea.

A multi-point link for a chassis of a motor vehicle. The multi-point link has at least one hollow profile portion including fiber-reinforced plastic and at least one load introduction element including a metallic material. The hollow profile portion, when viewed in cross section, has at least one hollow space formed as a circumferentially closed chamber. The hollow profile portion and the load introduction element are connected to one another in a common connection portion via a nondetachable glued plug-in connection. At least one stiffening element, which is fixedly connected to the hollow profile portion, is arranged in the chamber to increase the stiffness of the multi-point link.

An attachment interface is provided for connecting a vehicle composite component having a plate portion that is made of a fiber reinforced polymer and has a passage extending in a through manner along an axis. The attachment interface provides a metal attachment device, which includes an inner portion engaging the passage and an outer portion defining a connection point suitable to be connected to another vehicle element. The plate portion is axially sandwiched between two layers made of a fiber reinforced polymer composite material selected from the group consisting of BMC (Bulk Molding Compound), LFT (Long Fiber Thermoplastic) and DLFT (Direct Long Fiber Thermoplastic).

There is provided a suspension arm for a vehicle used in a suspension device of a vehicle. The suspension arm may include: a body portion constituting a basic body of the suspension arm; and a plurality of mounting portions configured to connect the suspension arm to a wheel-side member or a vehicle-body-side member. At least one of the plurality of mounting portions may be configured to include a bushing coupling portion and a fastening portion formed to extend from the bushing coupling portion to one side, such that the fastening portion may be coupled to a coupling portion provided on one side of the body portion in surface-contact with state.

An oblong cantilevered support includes a pair of latitudinally spaced apart oblong resilient members connected by a pair of longitudinally spaced apart blocks. The longitudinal spacing between the blocks can be adjusted. One or both of the members can have a tapered profile causing the stiffness of the member to vary along its length. Adjusting the spacing between the blocks and/or sliding a variable stiffness member longitudinally with respect to the blocks can adjust the stiffness of the overall support. Each member can be made from a unitary piece of fiber composite material such as a carbon fiber infused polymer wherein the orientations of the fibers are varied to provide both bending and torsional strength and stiffness that varies along the length of the member. The tapered geometry can be formed by a pair of parallely spaced apart oblique trapezoidal truncated pyramids interconnected by a webbing strip.
