The invention relates to a vehicle half shaft sealing structure which comprises a shell, an oil seal, a bush and a half shaft, and the oil seal is in contact connection with the shell; the bushing is in contact connection with the oil seal; and the half shaft is in contact connection with the bushing. The oil seal has the beneficial effects that 1, large-particle splashes such as broken stones and silt can be prevented from impacting the oil seal through the protective cover, and meanwhile, most dust, muddy water and the like are prevented from being in contact with the oil seal; 2, the first side lip, the second side lip, the first auxiliary lip and the second auxiliary lip form dustproof and waterproof effects, and leakage of internal oil liquid is effectively prevented; and 3, through the arrangement of the bushing, the oil seal is not in contact with the half shaft, the structure is simple in processing technology and good in sealing effect, the abrasion of the oil seal can be reduced, the half shaft sealing requirements of most vehicles are met, and the structure is particularly suitable for off-road vehicles with severe road conditions.

    本发明涉及一种车辆半轴密封结构,包括壳体、油封、衬套及半轴,所述油封与所述壳体接触连接;所述衬套与所述油封接触连接;所述半轴与所述衬套接触连接。本发明的有益效果在于:1、通过保护盖可以防止碎石、泥沙等大颗粒飞溅物撞击油封,同时隔绝掉绝大部分粉尘、泥水等接触油封;2、通过第一侧唇、第二侧唇、第一副唇及第二副唇形成防尘、防水的作用,有效阻止内部油液的渗漏;3、通过衬套的设置,使油封与半轴无接触,该结构加工工艺简单,密封效果良好,可以减少油封的磨损,满足大部分车辆的半轴密封要求,尤其适用于路况比较恶劣的越野车型。
