Abstract: A metal casting has a metal casting base body into which at least one metal insert body (1) is cast. The metal insert body has anti-twisting part-contours and is connected to the metal casting base body in a positively locking manner by the casting-in. To simplify the production of a stable metal casting, the metal insert body (1) has an elongate shape with a longitudinal axis and an outer mold contour with an unround cross section interrupted in the longitudinal direction by annular grooves (11-13) that fix the cast-in metal insert body (1) in the axial direction.

Abstract: An independent wheel suspension system for a motor vehicle includes an upper strut plane and a lower strut plane. Each of the upper strut plane and lower strut planes includes one longitudinal strut and one transverse strut. Each of the struts has a wheel side end for connection of a wheel holder and a body side end for connection of a body. The wheel-side ends of the longitudinal struts and the wheel-side ends of the transverse struts of the two strut planes are articulatedly connected either directly or indirectly to the wheel holder. The body-side ends of first struts of the two strut planes are articulatedly connected directly to the body. The body-side ends of second struts of the two strut planes are articulatedly connected indirectly to the body via a common coupling element.

Abstract: A brake caliper for a disk brake system of a motor vehicle, has a caliper body which is cast from a light metal alloy or from light metal, with a skeleton structure arranged inside the caliper body. The material of the skeleton structure has a higher modulus of elasticity than the material of the caliper body. The skeleton structure is cast into the caliper body so that the caliper body encases the skeleton structure.

Abstract: A motor vehicle has a rear axle cross member, from which two diagonal struts project forward in a V-shape, which diagonal struts are connected with their front end in each case to a vehicle longitudinal member. Here, it is important that an annular, closed stiffening structure is provided behind the rear axle cross member as viewed in the direction of travel. The stiffening structure is supported with its front end on the rear axle cross member and with its rear end, via struts which project rearward in a V-shape, on rear vehicle longitudinal members.

Abstract: A built brake disk for a wheel brake of a vehicle, in particular an automobile, has two friction rings, between which a plurality of spacers are arranged to form cooling ducts of an internal ventilation of the brake disk, and further has a nave, which is arranged coaxially with the friction rings and is firmly connected to the friction rings and/or to a plurality of spacers.
