The invention discloses a heavy-duty car axle shaft sleeve integrated with an oil seal mounting seat, which comprises an axle shaft sleeve, and is characterized in that a convex ring is arranged on the outer wall of the middle part of the axle shaft sleeve; the left end surface of the convex ring forms a bearing inner ring limiting surface; the right end surface of the convex ring forms a sleeve limiting surface; an annular protrusion is arranged on the circumferential outer wall of the protruding ring, and the outer end of the annular protrusion extends leftwards to form an oil seal supporting ring. The axle shaft sleeve, the protruding ring, the annular protrusion and the oil seal supporting ring are of an integrated structure. The axle shaft sleeve has the advantages that the axle shaft sleeve integrated with the oil seal installation base and used for the heavy-duty car is provided, the number of parts can be effectively reduced, the production cost is reduced, limiting of the axle shaft sleeve can be achieved through the oil seal installation base, and the axle housing structure is indirectly simplified.
本发明公开了一种集成有油封安装座的重型汽车用半轴套管,包括半轴套管,其创新在于:半轴套管中部外壁上设置有凸环;凸环的左端面形成轴承内圈限位面;凸环的右端面形成套管限位面;凸环的周向外壁上设置有环形凸起,环形凸起的外端向左侧延伸形成油封支撑环;半轴套管、凸环、环形凸起和油封支撑环为整体式结构。本发明的有益技术效果:提出了一种集成有油封安装座的重型汽车用半轴套管,该方案可以有效减少零部件数量,降低生产成本,并且还能利用油封安装座实现半轴套管的限位,间接地简化桥壳结构。
