HYDRODYNAMIC TRANSMISSION FOR RAIL VEHICLES

Transmission arrangement for transmitting drive power for a rail vehicle, having a primary shaft (3), a mechanical transmission stage, via which drive power can be introduced, a first hydrodynamic circuit (4 + 5 + 6), a second hydrodynamic circuit (8 + 10), an output shaft (29), and a transmission housing (1 + 1a + 1b + 1c), wherein a gearwheel (2) of the mechanical transmission stage, a bladed primary wheel (5) of the first circuit and a bladed primary wheel (10) of the second circuit are fastened, behind one another as viewed in the axial direction (x), on the primary shaft (3) in each casefixedly so as to rotate with it, and wherein a bladed secondary wheel (6) of the first circuit and a bladed secondary wheel (8) of the second circuit are connected to one another and to the output shaft fixedly so as to rotate, wherein the primary shaft (3) is mounted in the housing (1 + 1a + 1b + 1c) via at least three bearing points (12, 13, 15 + 16) in such a way that, as viewed in the axial direction (x), a first bear
