我们单位的斯太尔重型车,在使用中制动系统先后出现制动失效(抱死、制动调节臂调整不动等)故障。原因:该车制动凸轮轴黄油嘴设计位置不当,注油操作不便,缺乏润滑使滑动轴承套与凸轮轴锈死而制动失灵。为此,在不改变原结构的情况下,改进了原润滑方式,即改变制动凸轮轴与支承滑动轴承套的润滑方式(见图1)。 Our unit of Steyr heavy vehicles, brake system in use has appeared brake failure (lock, brake adjustment arm does not move, etc.) failure. Reason: The car brake camshaft grease nozzle design location, oil injection operation inconvenience, lack of lubrication to make the sliding bearing sleeve and the camshaft rust and brake failure. For this reason, the original lubrication mode is improved without changing the original structure, that is, the lubrication mode of the brake camshaft and the bearing sliding bearing sleeve is changed (see FIG. 1).
