The disclosure relates to a check rail for a wheel suspension of a wheel in a vehicle, wherein the wheel suspension may include a wheel carrier configured to support a wheel of a vehicle, the wheel carrier may include an elastic check rail body that may include a fiber-reinforced composite material with a first check rail end and a second check rail end, wherein the first check rail end is configured to be fastened to a structural body component of the vehicle, wherein the first check rail end is constructed without a bearing; and a pivot bearing on the second check rail end and configured to be rotatably fastened on the wheel carrier.

A suspension spring unit for a vehicle chassis can be positioned between a vehicle body and a wheel carrier. In some examples, the suspension spring unit may comprise at least four fiber composite leaf springs. The leaf springs may have a flat extent between two spring ends and may be connected to each other in pairs at a distance from each other. End connecting elements disposed over the spring ends may receive the spring ends so as to form at least two leaf spring pairs arranged in series. The leaf spring pairs may be connected to each other by central connecting elements via central regions between the spring ends of the leaf springs.

An aircraft landing gear assembly having a first landing gear element movably coupled relative to a second landing gear element to move between a first condition and a second condition. The aircraft landing gear assembly further comprises a fibre composite leaf spring formed from a plurality of composite layers and arranged between the first and second elements, the leaf spring being arranged to bend when the first element moves from the first condition to the second condition. The fibre composite leaf spring comprises a first region and a second region, wherein the number of composite layers in the first region is greater than the number of composite layers in the second region. The landing gear further comprises a mounting assembly arranged to engage the first region of the leaf spring to couple the leaf spring to the first landing gear element.

A leaf spring for a wheel suspension of a motor vehicle, comprises a first spring part made from a fiber reinforced plastic material and a second spring part made from a steel material. The first spring part and the second spring part are connected to each other. The ratio of the length of the first spring part to the length of the second spring part is larger than two. A leaf spring assembly can include such a leaf spring and receiving devices.

Leaf spring comprising at least one leaf of composite material that comprises: a central body (1), and two eyes (2), wherein the central body (1) comprises its longitudinal end zones (1.1) embedded in a cavity (2.1) of the eyes (2), wherein the sections transversal to the longitudinal direction of the central body (1) of the longitudinal end zones (1.1) of the central body (1) and the cavities (2.1) of the eyes (2) present increasing dimensions towards the longitudinal end of the leaf spring and that comprises fibre fabrics (7, 8, 9) of the central body (1) stacked in a Z-direction perpendicular to the longitudinal direction of the central body (1) and to the longitudinal direction of the hole (3) of the eyes (2) and comprises fibre fabrics (10, 11) of the eyes (2) stacked in a parallel direction to the longitudinal direction of the longitudinal axis of the hole (3).

Composite suspension components are disclosed. The components are made from resin containing elongated fibers (8). The arms of the suspension components may receive reinforcement (40) using different devices and methods. A composite torque rod also incorporates a tunable compliance feature.

A leaf spring assembly for a wheel suspension of a motor vehicle comprises a leaf spring of fibre-reinforced plastics for resiliently supporting a wheel carrier of the motor vehicle. The leaf spring comprises a first end portion, a spring portion, a bendable portion and a second end portion. The leaf spring further comprises a first receiving device for supporting the first end portion and a second receiving device for supporting a second end portion. The first receiving device and the second receiving device are designed such that the first end portion and the second end portion are held in a non-displaceable way relative to one another. At least one of the first and second receiving devices are designed such that the respective associated end portion is supported in a moment-free way in the receiving device.

A leaf spring for a wheel suspension of a motor vehicle, comprises a first spring part made from a fibre reinforced plastic material and a second spring part made from a steel material. The first spring part and the second spring part are connected to each other. The ratio of the length of the first spring part to the length of the second spring part is larger than two. A leaf spring assembly can include such a leaf spring and receiving devices.

A fastening shackle for fastening a leaf spring to a vehicle body of a vehicle includes: a first bearing end which can be fastened to the vehicle body, a second bearing end, and a shackle body connecting the first bearing end and the second bearing end. The first bearing end has an outer sleeve, an inner sleeve and a sleeve-shaped plastic plain bearing, the sleeve-shaped plastic plain bearing being arranged in the outer sleeve and being slidably mounted in the outer sleeve, and the inner sleeve being affixed to the sleeve-shaped plastic plain bearing. The leaf spring is mountable at the second bearing end.

A wheel support for arrangement on a motor vehicle axle is disclosed on a multi-link axle having a flange for receiving a wheel hub and at least two receptacles for rotatable coupling to links, the wheel support being coupled to a trailing link by means of thermal joining, which wheel support is distinguished by the fact that the wheel support is configured as a welded component and has a main body region which has at least two sheet metal components which are coupled to one another by way of thermal joining.
