The invention discloses a railway vehicle bogie which comprises a framework, an end shaft wheel pair, a secondary air spring and a primary suspension device, and the framework comprises two side beamsand a cross beam connected with the two side beams; the primary suspension device comprises axle boxes and primary air springs, and the end axle wheel pairs are connected with the corresponding axleboxes through bearings; the framework is of a hollow sealing structure. Primary air spring mounting seats are arranged at the two end parts of each side beam to mount primary air springs, and the primary air springs are communicated with the hollow cavity; a secondary air spring installation base is arranged in the middle of the side beam to install a secondary air spring, and the secondary air spring is communicated with the hollow cavity. Therefore, the secondary air spring, the framework and the primary air spring are communicated to form an integrated suspension system air path, when the load is greatly changed and suspension elastic creep occurs, the pressure in the primary air spring and the pressure in the secondary air spring are changed, finally, the purpose that the height between the vehicle body and the wheel set is not changed is achieved, and therefore the maintenance cost of the vehicle is reduced.

    本发明公开了一种轨道车辆转向架,包括构架、端轴轮对、二系空气弹簧和一系悬挂装置,构架包括两根侧梁和连接两根侧梁的横梁;一系悬挂装置包括轴箱和一系空气弹簧,端轴轮对通过轴承连接对应的轴箱;构架为中空密封结构;每根侧梁的两端部均设有一系空气弹簧安装座以安装一系空气弹簧,一系空气弹簧和中空腔连通;侧梁的中间位置设有二系空气弹簧安装座以安装二系空气弹簧,二系空气弹簧和中空腔连通。由此,二系空气弹簧、构架和一系空气弹簧连通形成一体的悬挂系统气路,当发生载荷较大变化及悬挂弹性蠕变时,改变一系、二系空气弹簧内的压强,最终实现车体和轮对之间高度不变的目的,从而减少车辆维护成本。
