Abstract: The invention relates to a bogie frame (1) for rail vehicles having at least two wheelsets, the bogie frame comprising two longitudinal members (3), which extend parallel to each other above the axle bearings, one or more cross-members (2) connected to the longitudinal members (3), and a receiving region (5) for functional elements, the bogie frame (1) being produced completely as a single casting of an aluminum alloy in a sand casting process, said casting having a hollow profile, which has cavities (10) in the interior and is stabilized by means of ribbings (8, 9). The invention further relates to a method for producing a bogie frame of this type and to a rail vehicle equipped with a bogie frame of this type.

Abstract: A method of producing hybrid castings, combined, movably joined from metal alloys in sand or permanent casting molds, where the method for manufacture of hybrid castings, especially with movable connections, in sand moulds or permanent moulds, comprises preparing metal components if the form of cast-in pieces, insert (5) for setting in the cope or drag (1,2), pre-heating to a given temperature depending on the material to increase the adhesion of the cast-in piece, insert (5) surface in the process of casting a hybrid casting (4), resulting in a final product comprising connected, movable hybrid components as an assembly for direct use.

Abstract: A device (1) for rail vehicles. The rail vehicles device incudes a predominantly hollow axle tube (2) extending along a longitudinal direction (LR) and ending in a first wheel flange (3), and a wheel support (4) extending opposite to the longitudinal direction (LR), having a wheel bearing (5), a second wheel flange (6) and a conical mandrel (7). The second wheel flange (6), the first wheel flange (3) and a wheel (8) are arranged therebetween with a wheel hub (9) connected to each other via a flange connection. The conical mandrel (7) is inserted from the wheel holder (4) in a positive-locking manner opposite to the longitudinal direction (LR) through the wheel hub (9) of the wheel (8) into the interior of the axle tube (2) and ends at the fastening element (11), which is arranged and cast into the axle tube (2) and is connected thereto.
