According to the bogie for flaw detection operation and the railway vehicle, the bogie framework is an H-shaped framework composed of the two side beams and the cross beam, and the whole framework is simple in structure and small in vertical occupied space. Each side beam comprises an air spring mounting seat and two half beams, the air spring mounting seats are integrally formed forgings, the cross beams are box-shaped beams, and the whole cross beams are of a #-shaped structure. According to the bogie frame, the cross beam is larger in anti-bending section coefficient, the overall strength and the bearing capacity are further improved, and a structural foundation is provided for improving the running speed of a train. In addition, a rotating arm axle box is arranged below each half beam, a primary suspension device is arranged between each rotating arm axle box and the corresponding half beam, and a secondary suspension device is arranged on the air spring mounting seat. The central traction device and the basic braking device are respectively arranged on the inner side surface and the outer side surface of the cross beam, and the flaw detection device is positioned below the bogie frame and mounted at the axle end part of the wheel set axle box device.
本发明提供的一种用于探伤检测作业的转向架和轨道车辆,转向架构架为两个侧梁和一个横梁构成的H型构架,整个构架结构简洁,垂向占用空间小。侧梁包括空簧安装座和两个半梁,空簧安装座为一体成型的锻件,横梁为箱型梁,横梁的整体呈井字形结构。本案中的转向架构架的横梁抗弯截面系数更大,整体强度和承载能力得到进一步的提升,为提高列车的运行速度提供了结构基础。此外,各半梁的下方均设置有转臂轴箱,转臂轴箱和半梁之间设置有一系悬挂装置,空簧安装座上设置有二系悬挂装置。中央牵引装置和基础制动装置分别设置在横梁的内侧面和外侧面,探伤装置位于转向架构架下方,安装于轮对轴箱装置的轮轴端部。
