The invention discloses a floating type chassis, an automatic vehicle body adjusting system and a control method. The automatic vehicle body adjusting system comprises the floating type chassis, a controller and a hydraulic system. The floating type chassis comprises a chassis body, longitudinal beam bodies on the two sides and supporting oil cylinders on the two sides. Each longitudinal beam main body is connected to the side part of the chassis body through at least two groups of rotating connecting rods; two ends of the rotating connecting rods and the supporting oil cylinders are rotationally connected with the chassis body and the longitudinal beam main bodies respectively; the supporting oil cylinders on the two sides are connected into a hydraulic system through oil cylinder proportional electromagnetic valves respectively. And the controller controls the telescopic action of the supporting oil cylinders on the two sides to change the height positions of the two side parts of the chassis body by controlling the left oil cylinder proportional electromagnetic valve and/or the right oil cylinder proportional electromagnetic valve according to a vehicle body inclination angle signal detected by an inclination angle sensor arranged on a vehicle body until the inclination angle of the vehicle body is changed to be within a preset range. The horizontal inclination angle of the whole machine can be automatically adjusted during slope operation, the oil consumption loss of slope operation is reduced, and the comfort and stability of the whole machine are improved.
本发明公开一种浮动式底盘、车身自动调整系统及控制方法,车身自动调整系统包括浮动式底盘、控制器和液压系统;浮动式底盘包括底架本体、两侧纵梁主体以及两侧支撑油缸;各纵梁主体通过至少两组转动连杆连接于底架本体的侧部,转动连杆和支撑油缸两端分别转动连接底架本体和纵梁主体;两侧支撑油缸分别通过油缸比例电磁阀接入液压系统;控制器根据车身上设置的倾角传感器检测的车身倾角信号,通过控制所述左油缸比例电磁阀和/或右油缸比例电磁阀,控制两侧支撑油缸的伸缩动作改变底盘本体两侧部的高度位置,直至车身倾角变化至预设范围内。本发明能够在斜坡作业时自动调节整机水平倾角的功能,减少斜坡作业油耗损失,提高整机的舒适性和稳定性。
