摘　　要：应用BFM1015系列某型号柴油机的车辆在行驶过程中出现机油压力低报警,检查发现凸轮轴衬套和三角堵盖存在不同程度的磨损,经分析得出磨损原因为柴油机取力器处转矩过大,使与其连接的传动机构产生偏移,进而导致凸轮轴润滑不足,发生衬套烧蚀、堵盖端面磨损等现象。针对该问题,设计柴油机取力器工作模拟装置模拟实际工况并进行试验,进一步验证磨损原因,并且得出柴油机与变量泵在安全工况下的试验数据,为取力器与柴油机、车用负载匹配性优化提供参考。A vehicle equipped with a certain type of BFM1015 diesel engine experienced a low oil pressure alarm on road.The inspection results showed that there was varying degree of wear on the camshaft bushing and triangular plug cover.By analysis,it was found out that the wear was caused by excessive torque at the power-take-off of the diesel engine,causing displacement of the connected transmission mechanism,resulting in insufficient lubrication of the camshaft,burning of the bushing,and wear of the plug cover end face.In response to this problem,a diesel engine power-take-off simulation device was designed to simulate actual working conditions.Experiments were carried out to verify the cause of wear,the test data of the diesel engine and variable displacement pump under safe working conditions was obtained,providing reference for optimizing the matching of power-take-off with diesel engine and vehicle load.
