东风ZKB-5型联合收割机的收割台及油缸为左右等距安装,而收割台的传动机构设在左侧,使割台左侧比右侧重几十千克。又因收割台的两个油缸是单向油缸,油路相通,机车作业或运行时收割台重心偏于左侧,将左侧油缸室的油压入右侧油缸室,逐渐造成过桥严重扭曲和机件的损坏 Dongfeng ZKB-5-type harvester combine harvester and cylinder is equidistant installation, and the harvesting platform transmission mechanism is located on the left, so that the left side of the header heavier than the weight of dozens of kilograms. Because the two headers of the harvesting platform are unidirectional cylinders, the oil paths are communicated with each other. The center of gravity of the harvesting platform in locomotive operation or operation is biased to the left, and the oil in the left cylinder chamber is pressed into the right cylinder chamber to gradually cause serious distortion of the bridge And mechanical damage
