目前,我省农业上使用的链轨拖拉机,主要型号是东方红-75(54),其次是红旗-100。这两种拖拉机行走装置技术保养的要点是: 1.清除泥垢:链轨拖拉机在作业中,行走装置极易粘附泥土,有时甚至会充塞整个行走装置。这样,不但会加速行走装置各摩擦面的磨损,而且当泥土塞满支重台车和引导轮的缓冲弹簧时,使弹簧失去减震作用,影响车架以及其它总成的使用 At present, the agricultural tractors used in agriculture in our province are mainly Dongfanghong -75 (54), followed by the Hongqi -100. The main points of technical maintenance of the two tractor walking devices are: 1. Clear dirt: the track tractor in the operation, the walking device is easy to stick to the soil, and sometimes even stuffed the entire walking device. In this way, not only the wear on the friction surfaces of the traveling device will be accelerated, but also the damping effect of the spring will be lost when the mud is filled with the buffer spring supporting the trolley and the guide wheel, thus affecting the use of the frame and other assemblies
