东方红—54/75拖拉机和东方红—60T 推土机在使用中发生脱轨现象,不但影响生产,而且造成车架、大轴等一系列零部件的损坏。履带脱轨时,由于缓冲装置退让行程的限制,使履带绷紧,而履带绷紧的力量主要作用在导向轮的拐轴上和驱动轮的后大轴上。如果前进Ⅰ档满负荷作业时脱轨,除履带绷紧力外,还得加上最终传动齿轮副啮合力与履带牵引力作用在后大轴上的合力。如果倒退带负荷或倒退转向时脱轨,除履带绷紧力外,还得加上两倍的驱动力。这力量对前边会使拐轴弯,大轴套碎,前梁从拐轴孔下边裂纹,顶弯张紧螺栓;对
Dongfanghong-54/75 tractors and Dongfanghong -60T bulldozers derailment occurs during use, not only affect the production, but also caused a series of parts such as frame, shaft and other damage. When the track is derailed, the crawler belt is tightened due to the limitation of the buffer device retraction stroke, and the tension of the crawler belt mainly acts on the camshaft of the guide wheel and the rear large shaft of the driving wheel. If the progress of the first gear full load derailment, in addition to crawler belt tautness, but also with the final transmission gear meshing force and crawler traction acting on the rear axle force. If you reverse the load or reverse steering derailed, in addition to track tension, you have to add twice the driving force. This force will make the crooked axis of the front bend, the large shaft sleeve broken, the front beam from the crooked hole below the crack, bending the top bolt;
