An integral bogie frame (14) for a bogie (10) of a rail vehicle comprises two side beams (24) and at least one support beam (28) extending in a transverse direction of the bogie frame (14) and rigidly connected to each of the two side beams (24). The support beam (28) comprises a support portion (30) for supporting a drive unit (16) of the bogie (10) and an elongated portion (32). The support portion (28) is connected directly to one of the two side rails (14) and to the other of the two side rails (14) by an elongated portion (32). The planar moment of inertia (M) and the polar moment of inertia (J) of any cross-section of the support portion (30) of the support beam (28) are at least twice, preferably at least 2.5, respectively, of any cross-section of the elongated portion (32) of the support beam (28).

    一种用于轨道车辆的转向架(10)的整体式转向架框架(14),其包括:两个侧梁(24)和至少一个支撑梁(28),该支撑梁(28)沿转向架框架(14)的横向方向延伸,刚性连接到两个侧梁(24)中的每个。支撑梁(28)包括支撑部分(30)和细长部分(32),该支撑部分(30)用于支撑转向架(10)的驱动单元(16)。支撑部分(28)直接连接到两个侧梁(14)中的一个,并且通过细长部分(32)连接到两个侧梁(14)中的另一个。支撑梁(28)的支撑部分(30)的任意横截面的平面惯性矩(M)和极惯性矩(J)分别是支撑梁(28)的细长部分(32)的任意横截面的平面惯性矩(M)和极惯性矩(J)的至少两倍,优选至少2.5倍。
