洛阳系列振动压路机在使用过程中,其变速器换向拨叉容易出现折断故障。我们通过维修实践,分析了变速器换向拨叉折断原因,总结出修复方法和改进措施。1.换向拨叉折断原因(1)结构强度不够洛阳系列振动压路机变速器换向拨叉设置了联锁装置,压路机换向行驶之前,不仅需要分离离合器,还要分开联锁装置,才能进行换向。换向拨叉壁厚仅为7.5mm,而且有折弯,造成其折弯部位应力集中,换向拨叉折断均发生在
Luoyang series vibratory roller in use, the transmission reversing fork prone to break the fault. Through the maintenance practice, we analyzed the reasons for the breakage of the shift fork of transmission and summarized the repair methods and improvement measures. 1. Reversing Fork Broken Reasons (1) the structural strength is not enough Luoyang series vibratory roller transmission shift fork set interlock, road roller before commuting, not only need to disconnect the clutch, but also to separate the interlock in order to change to. Reversing fork wall thickness of only 7.5mm, and there are bends, resulting in stress concentration bending parts, reversing fork break occurred in
