The invention discloses a hydraulic safety adjusting device which comprises a first adjusting oil cylinder, a second adjusting oil cylinder, a third adjusting oil cylinder and a fourth adjusting oil cylinder, the first adjusting oil cylinder and the second adjusting oil cylinder are installed between a front bogie and a vehicle body, and the third adjusting oil cylinder and the fourth adjusting oil cylinder are installed between a rear bogie and the vehicle body. A cushion valve group II is connected between the adjusting oil cylinder III and the adjusting oil cylinder IV; an oil path Z1 and an oil path Z2 are arranged between the buffer valve group I and the buffer valve group II; a piston rod and a cylinder end of the oil cylinder are adjusted to be connected with a vehicle body and a bogie respectively, and side rolling, nodding and sinking and floating movement of the vehicle body are directly resisted. Static pressure balance of two oil ways Z1 and Z2 can be achieved through a damping hole, static side sway of a vehicle is prevented, and overpressure protection is conducted on the two oil ways through an overflow valve. The energy accumulator is used for absorbing or supplementing hydraulic oil in the oil way and meanwhile providing anti-side-rolling restoring force.
本发明公开了一种液压安全调节装置,包括安装在前转向架和车体之间的调节油缸一和调节油缸二与安装在后转向架和车体之间的调节油缸三和调节油缸四,所述调节油缸一与调节油缸二之间连接有缓冲阀组一,所述调节油缸三与调节油缸四之间连接有缓冲阀组二;所述缓冲阀组一和缓冲阀组二之间设置有油路Z1和油路Z2;所述油路Z1和油路Z2之间连接有阻尼孔、溢流阀一和溢流阀二,本发明调节油缸的活塞杆、缸端分别连接车体与转向架,直接抗衡车体的侧滚、点头、沉浮运动。阻尼孔可实现Z1、Z2两油路静态压力平衡,防止车辆静态侧摆,溢流阀对两油路进行超压保护;蓄能器用于吸收或补充油路中液压油,同时提供抗侧滚回复力。
