The invention relates to the technical field of railway vehicles, and discloses a tumbler node for a bogie, which comprises an inner sleeve, a spacer bush, a rubber layer and an outer sleeve, the tumbler node is formed by vulcanizing and bonding the inner sleeve, the spacer bush, the rubber layer and the outer sleeve, the spacer bush is arranged on the outer wall of the inner sleeve, and the outer sleeve is arranged on the outer wall of the rubber layer. The section of the bottom section of the outer wall of the inner sleeve is inclined, the rubber layer is fixedly connected to the outer wall of the inner sleeve, and the inclination degree of the section of the outer wall of the rubber layer is the same as that of the outer wall of the inner sleeve; the thin-wall iron piece spacer bushes are additionally arranged in the rubber layers, so that the rigidity of the tumbler joint is effectively improved, the tumbler joint is installed in a primary suspension device of a bogie, and when an urban light rail train and a high-speed train run or turn, the tumbler joint can bear and transmit traction or braking longitudinal force, the stable running effect of the train is guaranteed, and the service life of the tumbler joint is prolonged. By arranging the special structure of the inner sleeve of the rotating arm node, the limiting effect of the rotating arm node when the rotating arm node is subjected to a limit load is ensured.

    本发明涉及轨道车辆技术领域,公开了一种转向架用转臂节点,包括内套、隔套、橡胶层和外套,且该转臂节点由内套、隔套、橡胶层和外套硫化粘接在一起,所述隔套设置在内套的外壁,所述外套设置在橡胶层的外壁,所述内套的外壁底部段的截面呈倾斜状,且所述橡胶层固定连接在内套的外壁,且所述橡胶层外壁截面倾斜程度与内套外壁的倾斜程度相同;本发明通过橡胶层层内部增加薄壁铁件隔套,有效增加了转臂节点的刚度,因而该转臂节点安装于转向架的一系悬挂装置中,在城市轻型轨道列车和高速列车运行或转弯时,能承担传递牵引或制动的纵向力,保证列车稳定运行的作用,通过设置转臂节点内套特殊的结构,确保了转臂节点在受到极限载荷时的限位作用。
