The invention relates to a spring arm device (1) for a motor vehicle, comprising two flanges (2) arranged at a distance from each other and which are made of a first fiber composite material (4) having fibers (6) each oriented in a longitudinal direction (5) of the flanges (2). The spring arm device (1) also comprises a web (3) which connects the flanges (2) and is made of a second fiber composite material (7) having the fibers (8) oriented at positive angles to the longitudinal directions (5) of the flanges (2). The spring arm device (1) can be fastened in end regions (15) opposite to each other to vehicle parts as part of a wheel suspension. The end regions (15) comprise end segments (14) of the two flanges (2) associated with each other and each comprise an end segment (9) of the web (3) that connects the end segments (14) of the flanges (2). Respective forces applied to the spring arm device (1) in the longitudinal direction (5) by means of the end regions (15) can be transmitted by means of the flanges (2). By means of a spring force, the flanges (2) counteract deformation of the spring arm device (1) caused by forces acting in a normal direction (16) of the web (3). Forces acting on the spring arm device (1) in a transverse direction (13) are transmitted from the web (3) to the end regions (15).

A fiber composite member includes an elongate main member and a fastening portion disposed at an end of the elongate main member, the fastening portion has a fastening opening for fastening the fiber composite member to a neighboring part. A reinforcement fiber bundle, which forms a fiber reinforcement of both the elongate main member and the fastening portion, has a first reinforcement fiber and a second reinforcement fiber which run substantially mutually parallel in a region of the elongate main member. A respective part of the first reinforcement fiber and the second reinforcement fiber in a transition region between the elongate main member and the fastening portion depart from a bundle profile in the region of the elongate main member and the respective parts of the first and second reinforcement fibers intersect with one another in the transition region.

An axle link for a motor vehicle includes a body-side connecting element and a wheel-side connecting element. The connecting elements are connected to one another by a rod element, comprised of a metal rod and a reinforcement casing. The metal rod is made of a ductile material and is anchored in the reinforcement casing at the connecting elements. The reinforcement casing is made of a brittle material and has a predetermined breaking point at a longitudinal position between the connecting elements.

The invention relates to a suspension unit, in particular for commercial vehicles, including an arm and a support element. The support element includes a support region and a support-side engagement region and comprises as a single piece, and the arm has an arm-side engagement region. A first engaging structure is provided on the arm-side engagement region, the engaging structure being attachable to a second engaging structure located on the support-side engagement region, and the support region includes a securing portion that fixes an air spring bellows and a rolling surface.

A stabilizer for a chassis of a vehicle, having a curved stabilizer body (2) that forms a torsion spring, with a pendulum support (5, 6) and with a connecting section (7, 8, 46, 48), the connecting section (7, 8, 46, 48) is made of a metal and connects the stabilizer body (2) to the pendulum support (5, 6). The connecting section (7, 8, 46, 48) and the stabilizer body (2) are connected to one another by a snap-in and/or latch joint. To reduce assembly effort and expense and, at the same time, to join the stabilizer body (2) to the pendulum support (5, 6) in a secure manner, the stabilizer (1) and the pendulum support (5, 6) are characterized in that the connecting section has an opening (22) in which a plastic bearing shell (11) is arranged for fitting of a joint ball (23) of the pendulum support (5, 6).

An independent wheel suspension for a two-track vehicle has a wheel carrier, a vibration damper designed and arranged in the manner of a damper strut, and a leaf spring element, which has, in particular, a fiber composite material or is made from a fiber composite material. The leaf spring element is oriented at least approximately in the transverse direction of the vehicle and is designed to provide a suspension function and, together with the vibration damper, to guide a vehicle wheel fastened to the wheel carrier when the independent wheel suspension is installed in a vehicle for functional usage. The leaf spring element is connected, on the wheel carrier end, to the wheel carrier via two rubber bearings, each having a bearing axis and a central bearing point, so as to be rotatable about the respective bearing axis of each rubber bearing and is designed to be connected, on the vehicle body end, to an axle support in a torsion-resistant manner and/or directly to a vehicle body.

An X-shaped spring device for a transportation vehicle wheel suspension having for each wheel side a first leaf spring and a second leaf spring made of fiber-reinforced plastics material and arranged one above the other. The first leaf spring is supported at the wheel side with one end and the second leaf spring is supported at the vehicle structure side with one end, and a first securing device on which the first leaf spring and the second leaf spring are joined and clamped, and which has a bearing for pivotable bearing at the vehicle structure side. The first securing devices of both wheel sides are connected to each other to provide a stabilizer action by using a spring.

A lightweight suspension upright or knuckle including: a bearing connection interface having a first sleeve element and a second, radially outer, sleeve element and further including a BMC/LFT/DLFT annular body; at least one attachment interface configured to connect the suspension upright or knuckle to a respective control or support element; and a supporting structural body mechanically connecting the bearing connection interface with the at least one attachment interface. The supporting structural body is shaped as a reticular frame including first blade elements chemically and mechanically interconnected to each other and to the outer lateral surface; each blade element consisting in one or more mats or plies of continuous fibers embedded in a polymer matrix, stacked onto one another and that have been compression molded together and with the annular body. Also, a method for obtaining a lightweight suspension upright or knuckle for a vehicle providing a bearing connection interface.

A mounting apparatus for vehicle suspension ball joints that are firmly affixed for operation, are easily adjustable in a generally vertical direction for precise tuning of suspension geometry for dynamic performance in multiple axes using an array of cylindrical shims tuned to match fastener distance and height with a socket that has mounting bolts that engage a scalloped cap.
