The invention discloses a hydraulic control system for a floating bridge of a chassis. The hydraulic control system aims to overcome the defect that in the prior art, a related method capable of discharging bubbles in an oil cylinder is lacked. The technical problem is solved through the following technical scheme: the floating oil cylinder comprises a left floating oil cylinder and a right floating oil cylinder, wherein a first balance oil pipe and a second balance oil pipe are communicated between the left floating oil cylinder and the right floating oil cylinder; first balance valves are arranged at two ends of the first balance oil pipe; second balance valves are arranged at two ends of the second balance oil pipe; the first oil duct is connected with the switching valve and high-pressure oil, and the second oil duct is connected with the switching valve and the oil tank; the third oil duct is connected with the switching valve and the first balance oil pipe, and the fourth oil duct is connected with the switching valve and the second balance oil pipe. The air bubbles can be conveniently discharged from the left floating oil cylinder and the right floating oil cylinder under the action of the switching valve and the high-pressure oil, and the supporting effect of the floating cylinders is better and better along with the reduction of the air bubbles in the using process.

    本发明公开了一种底盘浮动桥液压控制系统,旨在解决现有技术中缺少相关的能够将油缸内的气泡排出的方法的不足。本发明通过以下技术方案解决上述技术问题:包括:左浮动油缸和右浮动油缸,左浮动油缸和右浮动油缸之间连通有第一平衡油管和第二平衡油管;第一平衡油管的两端设置有第一平衡阀;第二平衡油管的两端设置有第二平衡阀;第一油道连接切换阀与高压油,第二油道连接切换阀与油箱;第三油道连接切换阀与第一平衡油管,第四油道连接切换阀与第二平衡油管。通过切换阀以及高压油的作用,可以非常方便的将气泡从左浮动油缸和右浮动油缸中排出,并且在使用过程中,随着气泡减少,浮动缸的支撑效果还会越来越好。
