An air spring having at least one composite part is provided. The air spring will have a top plate, a flexible sleeve, and a clamp ring coupled together by an injection molded collar. The injection molded collar will be formed to hold the top plate, flexible sleeve, and clamp ring in compression to form an air tight seal. In certain aspects, the top plate and/or the clamp ring may be formed from composites or metals.

A fluid damper is provided including a cylinder filled with a damping fluid, a piston base body shiftably guided in the cylinder along a stroke axis, and a valve disk spaced apart from a shell wall of the cylinder. The piston base body divides an inner space of the cylinder into a front space and a rear space along the stroke axis. In the piston base body, there is at least one channel connecting the front space to the rear space in a fluid-conducting manner. The valve disk is shiftably guided along the stroke axis between an opening position unblocking the at least one channel and a closing position closing the at least one channel. The valve disk has a central area extending radially outward from the stroke axis, the central area being free of apertures.

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.

Lateral support elements include an element wall with an exterior surface dimensioned to abuttingly engage an associated flexible wall and an interior surface that at least partially defines an element chamber within the lateral supporting element. Gas spring assemblies include a flexible spring member that at least partially defines a spring chamber. The lateral support element is disposed along and operatively connected to the flexible spring member. The element chamber can, optionally and in some cases, be disposed in fluid communication with the spring chamber. The gas spring assembly can include one or more end members operatively connected to the flexible spring member. Suspension systems and methods of assembly are also included.

A spring device (100) for a wheel suspension (200) for a vehicle (300) is described. The spring device (100) comprises an elongated elastic torsion device (102) configured to rotate about a central longitudinal axis (R) at a load (L). The torsion device (102) comprises elongated elastic elements (130) that comprise an internal cavity (132).

The invention relates to an article, more particularly an air spring bellows, having a one-layer or multi-layer main body with elastic properties, at least one layer of the main body being made up of a rubber mixture, a carbon black proportion of at least one carbon black, more particularly a total carbon black proportion of all carbon blacks, of the rubber mixture being less than 5 phr. The rubber mixture preferably contains aluminium hydroxide as a reinforcing filler. The rubber mixture can comprise chloroprene rubber as a base polymer.

A diaphragm holder for an oleo-pneumatic-type shock absorber includes a tubular body made of thermoplastic material, having a first end arranged to hold a diaphragm provided with flow restricting orifices and an opposite second end defining an arched bottom for withstanding pressure forces. Each of the two ends is provided with a localised mechanical reinforcement element forming an axial stop arranged to allow tensile stressing of the tubular body.

An adjustable shock assembly is disclosed herein. The adjustable shock assembly includes a damper body having a main chamber with a working fluid therein. An adjustable active valve assembly comprising: a first parallel flow pathway comprising an active valve; and a second parallel flow pathway comprising a firm mode blowoff stack and a firm mode adjuster to adjust a blowoff pressure of the firm mode blowoff stack. A main piston coupled with a piston shaft, and a fluid pathway fluidly coupling the main chamber with the adjustable active valve assembly which is fluidly coupled with a reservoir

A switching valve for an air spring arrangement of a motor vehicle, which switching valve has a valve housing arrangement which, in the installed state, is arranged between a first air volume and a second air volume. A valve closing member arrangement is actuatable by an actuator is provided such that the valve closing member arrangement, in a first position, fluidically connects the first air volume to the second air volume and, in a second position, fluidically separates the first air volume from the second air volume. The valve closing member arrangement is designed as a rotary slide arrangement. A rotary slide member with first openings is provided between two valve closing bodies, wherein, in the first position, the first openings correspond with second openings of the valve closing body such that a fluidic connection can be produced between the first and the second air volume.

An enclosure with a vortex-induced vibration suppression function and a method for suppressing vortex-induced vibration are provided. The enclosure is provided with suction through holes extending through a peripheral wall thereof, the suction through holes are distributed in a circumferential direction of the enclosure. The enclosure is further provided with a suction apparatus, and the suction apparatus can perform suctioning to the suction through holes from outside to inside, to restrain a boundary layer at an outer surface of the enclosure from being detached from the outer surface. By the suctioning, the boundary layer can be “adsorbed” on the outer surface of the tower, thereby restraining or directly preventing the boundary layer from being detached from the outer surface of the tower, and reducing or eliminating the cause of the vertex-induced vibration.
