The truck cast steel three big piece type bogie is easy to maintain. But since the grate weight under spring and the large operation strength during running, it is difficult for the bogie to keep the positive position. The critical speed of the snaking motion is low, which is inapplicable for high speed running. The other type of truck bogie is H type integrative truss. Its structure is complicate relatively, which is not easy to manufacture and maintain. But it can keep the positive position of the bogie preferably. And because it is adopted the structure of axle box one series elastic suspend, the weight under spring reduces. Which achieve the effective control to wheel sets and improve the running quality of the bogie distinctly.
货车铸钢三大件式转向架便于制造维修，但因其簧下质量大，在运行中轮轨作用力大，转向架难以保持正位，蛇行运动临界速度低，不适用于高速运行；货车转向架的另一种形式是"H"型构架一体式，结构较为复杂，不便于制造和检修，但它能够较好地保持转向架的正位，而且由于采用了轴箱一系弹性悬挂结构，降低了簧下质量，实现了对轮对的有效控制，明显地改善了转向架的运行品质。
