The invention discloses a track flaw detection car bogie and a track flaw detection car. The bogie comprises an axle box body and a framework, the framework is an H-shaped framework and comprises a framework cross beam and two framework side beams, and the framework cross beam is arranged between the two framework side beams; flaw detection equipment is arranged between every two adjacent axle box bodies in the length direction of the framework side beams; a primary double-layer steel spring group and a primary vertical shock absorber are arranged between the framework side beam and the outer end part of the axle box body, and the primary vertical shock absorber is arranged on the outer side of the primary double-layer steel spring group; a secondary hourglass spring, a secondary vertical shock absorber and a secondary transverse shock absorber are arranged at the upper part of the framework to form a secondary suspension system; the axle box body is a rotating arm positioning type axle box body, an axle end cover is arranged on the outer side face of the axle box body, a connecting lug is arranged on the axle end cover, and the connecting lug is connected with a rotating arm of flaw detection equipment through a rubber joint. According to the bogie of the track flaw detection vehicle, the wheel rail transverse force generated when a small curve line passes through can be reduced, and the track flaw detection vehicle can obtain better dynamic performance.
本发明公开一种轨道探伤车转向架和轨道探伤车,转向架包括轴箱体和构架;所述构架为H型构架,包括构架横梁和两个构架侧梁,构架横梁设置在两个构架侧梁之间;沿构架侧梁长度方向,相邻两个轴箱体间设有探伤设备;构架侧梁与轴箱体的外端部之间设有一系双层钢弹簧组和一系垂向减震器,一系垂向减震器设置在一系双层钢弹簧组的外侧;构架上部设有二系沙漏簧、二系垂向减震器和二系横向减震器构成二系悬挂系统;轴箱体采用转臂定位式轴箱体,轴箱体外侧面上设有轴端盖,轴端盖上设有连接耳,连接耳与探伤设备的转臂通过橡胶关节相连。本发明的轨道探伤车转向架,可减小小曲线线路通过时的轮轨横向力,使得轨道探伤车获得更优的动力学性能。
