The invention provides a hydro-pneumatic suspension of a snow sweeper and a height adjusting method, and relates to the field of snow sweepers, the hydro-pneumatic suspension comprises a frame, a front axle and a rear axle are arranged on the frame, two ends of the front axle are respectively provided with a front hydro-pneumatic spring, each front hydro-pneumatic spring is communicated with an oil tank through a corresponding front control valve group, and the front control valve group is communicated with a rear control valve group. Rear hydro-pneumatic springs are arranged at the two ends of the rear axle respectively, each rear hydro-pneumatic spring communicates with the oil tank through a corresponding rear control valve set, and displacement sensors are arranged in the front hydro-pneumatic springs and the rear hydro-pneumatic springs; each front hydro-pneumatic spring is communicated with a corresponding front energy accumulator through a corresponding front valve I, and each rear hydro-pneumatic spring is communicated with a corresponding rear energy accumulator through a corresponding rear valve I; and the controller is electrically connected with the displacement sensor, the front control valve group, the front valve I, the rear valve I and the rear control valve group. The left and right heights of the frame can be consistent, and the snow removal effect of the airport runway is good.
本发明提供了一种除雪车油气悬架及高度调整方法,涉及除雪车领域,采用的方案是:包括车架,车架上设置有前桥和后桥,前桥两端分别设置有前油气弹簧,每个前油气弹簧均通过相应的前控制阀组与油箱连通,后桥的两端分别设置有后油气弹簧,每个后油气弹簧均通过相应的后控制阀组与油箱连通,前油气弹簧和后油气弹簧均内置有位移传感器;每个前油气弹簧均通过相应前阀门一与相应的前蓄能器连通,每个后油气弹簧均通过相应的后阀门一与相应的后蓄能器连通;还包括控制器,控制器与位移传感器、前控制阀组、前阀门一、后阀门一和后控制阀组均电连接。本发明能够保证满足车架左右高度一致,机场跑道除雪效果好。
