The invention relates to the field of railway vehicles, and provides a light rail vehicle bullet train bogie and a light rail vehicle. The bullet train bogie of the light rail vehicle comprises a framework and a bogie, wherein the framework comprises a plate-shaped cross beam and L-shaped side beams; the middle part of the cross beam is hollow; the L-shaped side beams are respectively fixed at four corners of the cross beam and are oppositely arranged in pairs; the wheel pair comprises an axle and a pair of wheels mounted at the two ends of the axle; the axle box bodies are installed at the two ends of the axle and located on the inner sides of the pair of wheels, primary spring installation bases are arranged on the top faces of the axle box bodies and the bottom faces of the L-shaped side beams respectively, the axle box bodies and the L-shaped side beams are connected through primary springs, upper guide columns of the primary springs are fixedly inserted into the primary spring installation bases of the L-shaped side beams, and lower guide columns of the primary springs are fixedly inserted into the primary spring installation bases of the L-shaped side beams. And a lower guide post of the primary spring is fixedly inserted into a primary spring mounting seat of the axle box body. The structure can meet the requirements for light weight and small curve passing capacity of the bogie, and the bogie is compact in structure and high in small curve passing capacity.
本发明涉及轨道车辆领域,提供一种轻轨车辆动车转向架及轻轨车辆。轻轨车辆动车转向架包括:构架,包括中部镂空且呈板状的横梁和分别固定于横梁的四个拐角处并两两相对设置的L型侧梁;轮对,包括车轴和安装于车轴两端的一对车轮;轴箱体,安装于车轴的两端且位于一对车轮的内侧,轴箱体的顶面和L型侧梁的底面分别设有一系弹簧安装座,轴箱体与L型侧梁之间通过一系弹簧连接,一系弹簧的上导柱固定插设于L型侧梁的一系弹簧安装座内,一系弹簧的下导柱固定插设于轴箱体的一系弹簧安装座内。该结构能够满足转向架的轻量化和小曲线通过能力的要求,转向架结构紧凑,小曲线通过能力强。
