Abstract: The invention relates to a two-wheeled vehicle frame with two frame half-shells (1, 1?) which are joined so as to form a support frame (3), thereby forming at least one inner cavity (2). The support frame (3) has at least one separating surface (4) on which the two frame half-shells (1, 1?) rest against each other. The support frame (3) preferably has receiving areas (5, 6, 7) for a handlebar tube and/or a bottom bracket and/or an operator seat tube. The support frame (3) forms a rear structure (8) for assembling a rear wheel (9) at the rear end when seen in the travel direction (z). In order to form the rear structure (8), a left-hand support brace (10) when seen in the travel direction (z) and a right-hand support brace (11) when seen in the travel direction (z) are provided such that the rear wheel (8) can be mounted between the two support braces (10, 11).

Abstract: Longitudinal members for motor vehicles may generally include a supporting element that is releasably connectable to an energy absorption mechanism. The supporting element may typically include a joining zone that can be used to secure the supporting element to one or more chassis or drive components of the motor vehicle. The supporting element and the energy absorption mechanism may be comprised of fiber-reinforced plastic. More specifically, the supporting element may be comprised of a plurality of length portions having different fiber orientations. For example, a first length portion may have fibers oriented substantially parallel to a horizontal longitudinal plane about which the supporting element is positioned, whereas a second length portion between the first length portion and the energy absorption mechanism may have intersecting fibers oriented oblique to the horizontal longitudinal plane.

This sealing system comprises an elastic sealing strip which is disposed in an undercut manner in one of at least two tool parts to be sealed. It is characterized in that the sealing strip is essentially stressed perpendicular to the sealing strip surface when the tool parts are closed by means of the part of the tool pressing on the sealing strip and deforming it into the sealing gap which is present, in the direction of the mould cavity. The sealing strip comes into contact with the moulding compound without forming a mechanical connection therewith.

Abstract: A rim well with integrated flange made of fiber composite as well as to a method for manufacturing same. The flange is formed by inwardly directed protuberances of fiber layers of the rim well, wherein the fiber layers transition to the flange from the rim well without interruption of the fibers.

The fibers are deposited such that the fibers of at least one fiber layer have protuberances directed into the groove. A multipart mold, which makes it possible to reduce the width of the groove and thus a deformation of the protuberances, is preferably used.
