A wheel suspension unit for a motor vehicle having a longitudinal link, having a first end for pivotable vehicle-side connection, a second end for connection to a wheel carrier, and a blade-like link portion resilient in the direction of the transverse axis (Y) and rigid transversely relative thereto. The wheel suspension reduces the number of components by providing a longitudinal link having a resilient portion resilient toward the longitudinal axis (X), wherein the longitudinal link is at least partially produced from a fiber-reinforced plastics material.

A leaf spring device for a vehicle, comprising a leaf spring apparatus made of a fiber composite plastic, a first bearing point provided at a first end section of the leaf spring apparatus for supporting the leaf spring device on the vehicle, the first bearing point comprising exactly three rotational degrees of freedom, and a second bearing point provided at a second end section of the leaf spring apparatus facing away from the first end section for supporting the leaf spring device on the vehicle, the second bearing point comprising exactly one rotational degree of freedom.

A spring device for a motor vehicle wheel suspension that includes a first leaf spring made of fiber-reinforced plastic and a second leaf spring made of fiber-reinforced plastic. The second leaf spring is shorter than the first leaf spring and together with the first leaf spring forms a V-shaped structure, which, in the region of the joined ends of the V-shape, has a first fastening device for the vehicle-body-side support and at the free ends of the V shape has a second fastening device on the first leaf spring for wheel-side support and a third fastening device on the second leaf spring for vehicle-body-side support.

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.

A leaf spring assembly resiliently supporting a wheel carrier on a vehicle body of a motor vehicle. The leaf spring assembly including first and second spring leaves and a clamp having a clamping part exerting a clamping force whereby the first and second spring leaves are held together by the clamp. A bridging part arranged between the first spring leaf and the clamping part transmits at least part of the clamping force from the clamping part to the first spring leaf bridging the second spring leaf and reducing the clamping force exerted thereon.

The present disclosure relates to a method for producing a leaf spring 1 for a vehicle axle suspension, wherein the at least one spring arm 5 bordering on a clamping portion 2 is formed from a rod-shaped preliminary material 7, 8 by a rolling process. By the rolling process for shaping the leaf spring a preliminary material rod 7, 8 having a rounded cross-sectional geometry is rolled out to produce a rectangular cross-sectional geometry in the clamping portion 2 and in the at least one spring arm 5, and thus the portion of the preliminary material rod 7, 8 provided for forming the clamping portion 2 in the finished leaf spring 1 is also reshaped by the rolling process and as a result a rolled structure is also formed therein.

Described is a fibre composite component designed as a spring, comprising at least one spring section and at least one force transfer structure (2). In the end portion forming or surrounding the force transfer element (3) the fibre composite material of the fibre composite component (1) is divided, in a plane perpendicular to the longitudinal direction of the force transfer structure (2), into at least two fibre composite material strands (4, 4.1, 4.2). Two adjacent fibre composite strands (4, 4.1, 4.2) nm in opposite directions, overlapping over a specific angular portion and each forming an eye, with their mutually opposed side faces (7) force-transmittingly connected in the overlapping portion.

A leaf spring assembly for a wheel suspension of a motor vehicle including a leaf spring resiliently supporting of a wheel carrier on a vehicle body of the motor vehicle. The leaf spring has a first end portion, and a diametrically or longitudinally, opposite second end portion fastened, pivotably mounted, to the vehicle. The leaf spring includes a suspension portion extending between the two end portions. The leaf spring includes two spring leaves held pressed one against the other by a first clamp in the suspension portion and are held pressed one against the other by a second clamp distanced or longitudinally spaced from the first clamp. The position of the second clamp, its position on the leaf spring, is variable in the direction of the longitudinal axis of the leaf spring.

A method for the production of a fiber plastic composite component may include the following steps: creating a load-adapted multilayer preform structure made of pre-fabricated multi-layered sub-preforms, and inserting the preform structure into a form-shaping tool. A system for the production of a fiber plastic composite component may include the following: a first manufacturing station for forming a load-adapted multi-layer preform structure from prefabricated multilayered sub-preforms, and a form-shaping tool for consolidating the preform structure.

An axle arrangement for a motor vehicle includes two opposite wheel carriers which are connectable to a bodywork of the motor vehicle via links, and a transverse leaf spring which is connected to the two wheel carriers. The transverse leaf spring is manufactured as one piece from fiber-reinforced plastic, has at least two bands spaced apart from one another and is at least partially integrated in a shear field. The shear field extends between the two wheel carriers and on both sides is connected fixedly to the body or the bodywork of the vehicle and projects beyond the transverse leaf spring, as viewed in the longitudinal direction of the vehicle.
