Gas spring end members include an end member wall with a longitudinal axis. End member wall includes an end wall portion and an outer wall portion. Outer wall portion extends peripherally about axis and is dimensioned to receivingly engage a flexible spring member. Rib wall portions are spaced around axis with each of rib wall portions projecting axially from end wall portion toward a rib end surface portion. Rib wall portions also include a rib edge surface portion spaced inward from an inner side surface portion of outer peripheral wall portion such that a gap is formed therebetween. Gas spring assemblies including one or more of such end members, and suspension systems including one or more of such gas spring assemblies are also included.

A steering system, in particular for use in commercial vehicles, having a base body and a retaining element, wherein the base body has a contact surface on the base body side and the retaining element has a contact surface on the retaining side, wherein the base body has a bearing area for a pivotable suspension at its first distal end, wherein the contact surface on the base body side is arranged at the end of the base body opposite the first distal end, wherein the retaining element has a fastening section for fastening a spring element, wherein the retaining element can be fixed or is fixed to the base body by means of an adhesive introduced between the contact surface on the base body side and the contact surface on the retaining side, and/or wherein an axle body with a contact surface on the axle side is provided, wherein the base body can be fixed or is fixed to the axle body by means of an adhesive introduced between the contact surface on the base body side and the contact surface on the axle side, wherein the retaining element can be fixed or is fixed to the axle body by means of an adhesive introduced between the contact surface on the axle side and the contact surface on the retaining side.

A vehicle with suspension-controlled motion resistance members is provided. The vehicle includes a body and a chassis coupled to a base of the body. The vehicle further includes a motion resistance member that is coupled to a base surface of the chassis, a wheel assembly coupled to the chassis, and a suspension unit coupled to the wheel assembly and the chassis. In an actuated state, the suspension unit is configured to move the chassis in a first direction until at least a portion of the motion resistance member contacts a ground below the base surface of the chassis.

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 chassis link for a motor vehicle having load introduction elements connected by a straight profile portion of fiber-reinforced plastic. The profile portion and load introduction elements are connected via an adhesive connection in a common connection portion in which an end portion of the load introduction element and an end portion engage another in positive engagement. On both sides of a profile portion neutral fiber plane, the adhesive connection has longitudinal adhesive layers extending in a longitudinal direction of the profile portion and parallel to one another in a vertical. In vertical direction of the profile portion the longitudinal adhesive layers have a cross-sectional area becoming larger with increasing distance from the neutral fiber plane so that a relief is brought about in regions of the adhesive connection which have a relatively large distance from the neutral fiber plane in vertical direction of the profile portion.

A spring, in particular a flat spring (5), for use in connection with a vehicle, has a middle region (6) which has a curve with a first curve direction, as well as two edge regions (7). In an unladen state, the edge regions (7) each have a curve with a second curve direction and vertices (10), with the second direction of curve being opposed to the first direction of curve. The flat spring (5) has a vertex axis (11) running through the vertices (10) of the curves of the edge regions (7). End regions (8) of the edge regions (7) are tilted away from the vertex axis (11) toward the side of the vertex axis (11) on which the middle region (6) lies.

An oblong, resilient, semi-rigid cantilevered support member can have a pair of spaced apart tapering rods joined by a medial webbing strip. The strip can have a substantially planar back surface tangent with the back edges of the tapering rods to form a substantially quadrangular and planar back side to the member albeit with rounded side edges. The strip can have a generally trapezoidal front surface that is scalloped in a concave manner. The member can be made from a unitary piece of fiber composite material where 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 member can be coupled to a second latitudinally spaced apart oblong resilient member connected by a pair of longitudinally spaced apart blocks for greater adjustability.

A strut assembly including a spring to help absorb impacts and a shock absorber to help control motion of the spring is disclosed. The shock absorber includes a base assembly and is mounted between a top mount assembly and a knuckle. The top mount assembly mounts to the body of the vehicle and helps support the spring. An upper spring seat is adjacent the top mount assembly and receives one end of the spring. A lower spring seat formed of a composite material is supported by the base assembly and is adapted to support another end of the spring. The lower spring seat includes at least one reinforcing element having a plurality of reinforcing cords disposed between an upper surface and a lower surface for improving impact resistance thereof.

A composite material bush may include a center plate; and an outer foam which is arranged outside the center plate to surround the center plate and is made of different kinds of materials.

The invention relates to a running gear structure (4) for a commercial vehicle. The running gear structure comprises a lower transverse strut (8) and an upper transverse strut (9). The lower transverse strut (8) and said upper transverse strut (9) are fixedly connected to each other. The upper transverse strut (9) comprising two recesses (12, 13) which limit a space (14) located above the lower transverse strut (8). The space (14) is open at least in upper direction and dimensioned for accommodating a suspension spring (6). Preferably, an axle body and longitudinal swinging arms (22, 23) of the running gear structure (4) have a skeletal design with a plurality of struts (5). It is possible that the running gear structure (4) is L-shaped in a side view. Here, one leg of the L is formed by a horizontal structure part forming the longitudinal swinging arms (22, 23) whereas the other leg of the L is formed by a vertical structure part forming the axle body.
