16 ABSTRACT A unitary bogie frame (14) for a bogie (10) of a rail vehicle, includes: two side beams (24) and at least one support beam (28) extending in the transverse direction of the bogie frame (14), rigidly connected to each of the two side beams (24). The support beam (28) includes a support portion (30) for supporting a drive unit (16) of the bogie (10) and a slender portion (32). The support portion (28) is directly connected to one of the two side beams (14) and is connected to the other of the two side beams (14) through the slender portion (32). The planar second moment of area (M) and the .. polar second moment of area (J) of any cross section of the support portion (30) of the support beam (28) are at least twice as great, preferably at least 2.5 times as great, as the planar second moment of area (M) and the polar second moment of area (J), respectively, of any cross-section of the slender portion (32) of the support beam (28).

    16 ABRÉGÉ : Un cadre de bogie unitaire (14) pour un bogie (10) dun véhicule ferroviaire comprend : deux longerons (24) et au moins un bras support (28) sétendant dans le sens transversal au cadre de bogie (14) et étant rigidement raccordé aux deux longerons (24). Le bras support (28) comprend une partie de support (30) pour soutenir un mécanisme dentraînement (16) de bogie (10) et une partie mince (32). La partie de support (28) est raccordée directement à lun des deux longerons (14) et est raccordée à lautre longeron (14) au moyen de la partie mince (32). Le deuxième moment de laire plan (M) et le deuxième moment de laire polaire (J) de toute section transversale de la partie de support (30) du bras support (28) sont au moins 2 fois plus grands, de préférence 2,5 fois plus grands que le deuxième moment daire M et le deuxième moment daire J respectifs de toute section transversale de la partie mince (32) du bras support (28).
