The invention relates to a bogie of an urban automatic passenger transport system vehicle. The bogie comprises a guide frame serving as a main body support of the bogie, and an axle, and the lower part of the axle is connected with the upper part of the guide frame through a pivotal bearing for connecting an upper vehicle body; the bogie further comprises a pair of traveling wheels which is arranged on the two sides of the axle, travels on a track beam and is used for bearing the overall weight of the bogie, and guide wheels which are mounted on the front side and the rear side of the guide frame and used for guiding the bogie. Compared with the prior art, the bogie provided by the invention has the advantages that a non-linear hydro-pneumatic spring is used as a transverse shock absorber to buffer transverse vibration, the rigidity and damping are variable, and the dynamic performance can be changed through oil filling and air filling so as to adapt to different line conditions; and two pairs of longitudinal pull rods are used for transmitting longitudinal force, so that the traction effect is achieved, and the anti-nodding effect is also achieved.
本发明涉及一种城市自动旅客运输系统车辆的转向架,包括:导向框,作为转向架的主体支撑;轴桥,下部通过回转轴承连接在所述导向框上部,用于连接上部车体;一对走行轮,设置在所述轴桥两侧,行走在轨道梁上,用于承载转向架整体重量;及导向轮,安装在所述导向框的前后两侧,用于转向架的导向。与现有技术相比,本发明使用非线性的油气弹簧作为横向减振器来缓和横向振动,具有变化的刚度与阻尼可以通过充油、充气来实现动态性能的改变以适应不同的线路条件;使用两对纵向拉杆传递纵向力,既起到了牵引的作用,又起到抗点头的作用。
