The invention relates to an agricultural machinery leveling vehicle body based on a hydraulic cylinder with a displacement sensor. The vehicle body comprises rear wheels, the hydraulic cylinder with the displacement sensor, a rear axle cross beam, a longitudinal beam, a front axle cross beam, a hydraulic cylinder jack, a transmission shaft, a cross beam connecting plate, a starting structure, a V-shaped thrust rod base, a rear axle, a straight push vertical rod base, a straight push vertical rod, a V-shaped thrust rod and a hydraulic cylinder base, a displacement control oil cylinder of a quadrilateral steering mechanism, a displacement control valve, a hydraulic oil tank, an oil supplementing pump, a filter, a bidirectional constant displacement motor, an overflow valve, an oil supplementing one-way valve, a variable pump, an oil supplementing overflow valve, a hydraulic pump, a filter, an overflow valve, a two-position two-barrel electromagnetic reversing valve, a hydraulic cylinder,a pressure gauge, a hydraulic control one-way valve, a three-position four-way electromagnetic reversing valve, and a one-way valve. The leveling vehicle body is characterized in that when the vehicle body inclines, the hydraulic cylinder with the displacement sensor is driven to move, the hydraulic cylinder converts the value of the displacement sensor carried by the hydraulic cylinder into theinclination amount, and after a series of algorithms of a vehicle body leveling system, leveling of the whole vehicle body is completed by controlling the direction and flow of a hydraulic motor and areversing valve. The whole agricultural machine is driven in a hydrostatic mode, mechanical energy of an engine is used to drives hydraulic pump to be converted into hydraulic energy, high-pressure oil output by the hydraulic pump enters the motor installed on a gearbox through an operation adjusting device, the hydraulic energy is converted into the mechanical energy again to drive a harvester to move, and the whole system transmits the high-pressure oil through a hydraulic oil pipe to transmit power.
本发明涉及一种基于带有位移传感器的液压缸农机调平车体,包括包括后轮,带有位移传感器的液压缸,后桥横梁,纵梁,后轮,前桥横梁,液压缸上顶,传动轴,横梁连接板,启动结构,V型推力杆底座,后桥,直推立杆底座,直推立杆,V型推力杆,液压缸底座,四边形转向机构排量控制油缸,排量控制阀,液压油箱,补油泵,过滤器,双向定量马达,溢流阀,补油单向阀,变量泵,补油溢流阀,液压泵,过滤器,溢流阀,两位两桶电磁换向阀,液压缸,压力表,液控单向阀,三位四通电磁换向阀,单向阀。其特征在于:车体在发生倾斜时,会带动带有位移传感器的液压缸运动,而该液压缸会将本身携带的位移传感器数值转换成倾斜量,经过调平车体系统的一系列算法之后,通过控制液压马达的方向和流量还有换向阀来完成对整车体的调平。整体农机采用静液压驱动,将发动机的机械能带动液压泵转换为液压能,而液压泵输出的高压油经操纵调节装置进入装在变速箱上的马达,重新将液压能转化为机械能,驱动收割机运动,整个系统通过液压油管传送高压油来传送动力。
