The invention discloses a novel framework for an inner axle box bogie of a railway vehicle. The framework is composed of two transversely arranged cross beams and a box type longitudinal beam; the cross beams are arranged right above an axle, and the longitudinal beam is connected between the middle parts of the two cross beams; the longitudinal beam is mainly an installation foundation of secondary suspension, and a secondary vertical shock absorber installation base, a traction device installation base, a secondary stop installation base and a secondary spring installation base are all arranged on the longitudinal beam. Two small longitudinal beams are arranged at the two ends of each cross beam and can also serve as installation bases of part of secondary suspension, and anti-snaking shock absorber installation bases, transverse shock absorption installation bases, unit braking system hanging bases and braking lifting lug installation bases are all arranged on the cross beams. Except a wheel disc brake device, all bogie suspension parts can be placed in the internal space of the bogie, so that the purpose of remarkably reducing the weight of the bogie is achieved, and the running performance of the whole bogie is improved.

    本发明公开了一种用于轨道车辆内轴箱转向架的新型构架,所述构架由两个横向布置的横梁和一个箱型纵向梁组成,所述横梁布置在所述车轴正上方,所述纵向梁连接于两个所述横梁中部之间;所述纵向梁主要是二系悬挂的安装基础,其中二系垂向减振器安装座、牵引装置安装座、二系止挡安装座和二系弹簧安装座均布置于所述纵向梁上。所述每个横梁两端是两个小的纵向梁,亦可以作为部分二系悬挂的安装基础,其中抗蛇行减振器安装座、横向减振安装座、单元制动系统吊座和制动吊耳安装座均布置在所述横梁上。本构架除了轮盘制动装置所有转向架悬挂部件均可放在转向架内部空间,从而达到显著降低转向架重量的目的,提高整个转向架的运行性能。
