Abstract: A method for producing a structural component part (1, 33) from a fiber-reinforced plastic according to a three-dimensional winding process. A threadlike fiber material (12) is supplied on at least one bobbin (18) and constructed as a towpreg semifinished product is wound around at least one filament carrier (11) in a winding pattern by a computer-controlled winding device. The towpreg semifinished product is a mixture (30) of a thermoset resin, a hardener, an accelerator and plastic fibers (29) embedded in the mixture (30). The fiber material (12) is guided on the filament carrier (11) by a guide element (24) having a circular outlet cross section and arranged at a fiber guide device (25), the fiber material (12) deflected by the guide element (24) when the winding pattern is formed. The fiber material (12) is brought in contact with the guide element (24) during a deflection.

Abstract: A wheel suspension for a vehicle includes: a steering knuckle support; a steering knuckle mounted at the steering knuckle support so as to be swivelable around a steering axis; a vehicle wheel mounted at the steering knuckle so as to be rotatable around a wheel rotational axis; and a plurality of links by which the steering knuckle support is articulated at a vehicle frame such that the steering knuckle support is movable in a vertical direction (z) of the vehicle relative to the vehicle frame. A first one of the links is configured as a first control arm configured as a four-bar link, and a second one of the links is configured as a second control arm arranged offset relative to the first link in the vertical direction (z) of the vehicle, and wherein the second link is configured as a two-bar link that is adjustable in length.
