The invention discloses an automobile steering drive axle. The automobile steering drive axle comprises a speed reducer shell, a rear cover, an axle shell body, a pair of shaft sleeves and a pair of half shafts, the speed reducer shell is installed at one side of the axle shell body, the rear cover is installed at the side, opposite to the speed reducer shell, of the axle shell body, and holes areformed at the two ends of the axle shell body. The pair of shaft sleeves is fixedly connected with the two ends of the axle shell body, the pair of half shafts is inserted into the pair of shaft sleeves, and a pair of sealing outer ring structures is installed on the pair of half shafts and the shaft sleeves. The invention relates to the technical field of automobiles. The automobile steering drive axle adopts a half-shaft structure, the outer ends of the half shafts are sealed and wrapped through the sealing outer ring structures, a sealing part is lubricated through a thixotropic lubricating and sealing structure, and meanwhile sealing and plugging are conducted through the effect that the viscous force is large in the standing process. Therefore, the resistance can be reduced as much as possible while the connecting part of the half shafts and an axle shell of an automobile is kept sealed.
本发明公开了一种汽车转向驱动桥,包括减速器壳、后盖、桥壳主体、一对轴套管以及一对半轴,所述减速器壳安装于桥壳主体一侧,所述后盖安装于桥壳主体与减速器壳对立一侧,所述桥壳主体两端开孔,一对所述轴套管与桥壳主体两端固定连接,一对所述半轴插装于一对所述轴套管内,一对所述半轴套管上安装有一对密封外环结构;本发明涉及汽车技术领域,该汽车转向驱动桥采用半轴式结构,利用密封外环结构对半轴外端进行密封包裹,并且利用触变性的润滑密封结构对密封部位进行润滑的同时,利用其在静置时粘滞力较大的效果进行密封封堵,从而使得汽车的半轴与桥壳连接部位保持密封的同时,最大可能减小阻力。
