本发明公开了一种后驱动桥输入端密封结构及矿用自卸车,后驱动桥输入端密封结构包括复合型端盖、凸缘叉结构、防尘罩、骨架油封和防尘密封圈;所述骨架油封和防尘密封圈安装在所述复合型端盖上,达到更好的密封效果;所述凸缘叉结构安装在输入螺旋齿轮轴上,与骨架油封唇口配合;所述防尘罩安装在凸缘叉结构的阶梯端面上,用于阻挡杂物进入损坏防尘密封圈。采用复合型端盖和双密封结构,极大提高了后驱动桥输入端的密封性能,同时本发明拆装方便,维护更换密封件时,人工成本低。

    The invention discloses a rear drive axle input end sealing structure and a mining dump truck. The rear drive axle input end sealing structure comprises a composite type end cover, a flange yoke structure, a dustproof cover, a framework oil seal and a dustproof sealing ring; the framework oil seal and the dustproof sealing ring are installed on the composite type end cover to reach a better sealing effect; the flange yoke structure is installed on an input helical gear shaft, and is matched with a framework oil seal lip; and the dustproof cover is installed on the ladder end surface of the flange yoke structure, and is used for preventing sundries from entering and damaging the dustproof sealing ring. By adopting the composite type end cover and a double-sealing structure, the sealing performance of the rear drive axle input end s greatly improved, meanwhile, the disassembly and assembly are convenient, and when a sealing piece is maintained and replaced, the labor cost is low.
