The invention discloses a sealing structure, and relates to the technical field of part sealing. The sealing structure comprises a transmission mechanism, a half shaft and an oil seal. The transmission mechanism comprises a shell and an output shaft, the shell is provided with an inner cavity, and the shell is provided with a through hole communicated with the inner cavity; the output shaft is arranged in the inner cavity and provided with an extending section inserted into the penetrating hole, and a mounting hole coaxial with the extending section is formed in the side, away from the inner cavity, of the extending section. The half shaft is inserted into the mounting hole and is in transmission connection with the output shaft; and the oil seal sleeves the extension section and is connected with the shell. According to the sealing structure, the probability of lubricating liquid leakage and the probability of abrasion between the half shaft and the output shaft are reduced, the structure is simple, and the cost is low. The invention further provides an automobile comprising the sealing structure, and the automobile is provided with the sealing structure, so that the probability of lubricating liquid leakage and the probability of abrasion of the half shaft and the output shaft are reduced; in addition, due to the fact that the sealing structure is simple in structure and low in cost, the cost of the automobile can be reduced.
本申请公开了一种密封结构,涉及零部件密封技术领域。密封结构包括传动机构、半轴和油封;传动机构包括壳体和输出轴,壳体具有内腔,壳体开设有与内腔连通的穿孔;输出轴设于内腔,输出轴具有插入穿孔的延伸段,延伸段远离内腔的一侧开设有与延伸段共轴设置的安装孔;半轴插设于安装孔并与输出轴传动连接;油封套设于延伸段并与壳体连接。本申请的密封结构降低了润滑液渗漏的几率和半轴与输出轴发生磨损的几率,且结构简单、成本较低。本申请同时提供了一种包括上述密封结构的汽车,该汽车通过设置密封结构,降低了润滑液渗漏的几率以及半轴与输出轴发生磨损的几率;另外,由于密封结构的结构简单且成本较低,因此还能够降低汽车的成本。
