The invention discloses a hydraulic variable stiffness anti-side-rolling device for a train, which comprises a left hydraulic cylinder, a right hydraulic cylinder, a hydraulic runner and a variable stiffness return device, the left hydraulic cylinder and the right hydraulic cylinder are respectively connected with a carriage and a bogie on the left side and the right side of the bogie, and the hydraulic runner is communicated with the left hydraulic cylinder and the right hydraulic cylinder; when the carriage rolls laterally, the hydraulic cylinder on one side bears acting force and transmits the acting force to the hydraulic cylinder on the other side through the hydraulic flow channel in the form of counter-acting force, the counter-acting force acts on the bogie and the carriage through the hydraulic cylinder on the other side, and meanwhile, the hydraulic cylinder on the other side acts on the bogie and the carriage. The variable-rigidity force return device can conduct variable-rigidity buffering on the side rolling force of the compartment at least when side rolling exceeds the set amplitude, and return force enabling the compartment to return to the posture before side rolling is formed. The invention has the advantages that the hydraulic pipeline can be randomly bent and arranged without occupying precious space on the bogie, so that the overall design of the bogie can be more scientific and reasonable.
本发明公开了一种列车用液压变刚度抗侧滚装置,包括左液压缸、右液压缸、液压流道和变刚度回力装置,所述左液压缸和右液压缸分别在转向架的左侧和右侧连接车厢和转向架,液压流道连通左液压缸和右液压缸,变刚度回力装置设置在液压流道上,车厢发生侧滚时,一侧液压缸将受到作用力并将受到的作用力以反作用力的形式通过液压流道传递到另一侧的液压缸,并由该另一侧的液压缸将该反作用力作用于转向架和车厢,同时,变刚度回力装置至少在侧滚超过设定幅度时能够对车厢侧滚力进行变刚度缓冲并形成使车厢恢复侧滚前姿态的回复力。其优点在于:液压管路可以任意弯曲布设,无需挤占转向架上宝贵的空间,使得转向架总体设计能够更加科学合理。
