The invention relates to the technical field of vehicle engineering, and discloses an automobile steering mechanism and a vehicle. The automobile steering mechanism comprises a main shell and a power-assisted shell, and a first transmission assembly is arranged in the main shell; the boosting shell is provided with a mounting cavity, a second transmission assembly is arranged in the mounting cavity, and the second transmission assembly is in transmission connection with the first transmission assembly; the power-assisted shell further comprises an isolation unit, and the isolation unit can isolate grease of the second transmission assembly in the power-assisted shell. The automobile steering mechanism further comprises a sealing unit. The sealing unit comprises a sealing part and a sealing piece. The sealing part comprises local sealing surfaces which are respectively arranged at the axial end parts of the boosting shell and the main shell; the sealing piece is arranged on the radial inner side of the sealing part. Lubricating grease of the second transmission assembly is effectively prevented from being mixed into the first transmission assembly, and oil leakage of the joint part of the main shell and the power-assisted shell is prevented.
本发明涉及车辆工程技术领域,公开一种汽车转向机构及车辆。其中汽车转向机构包括主壳体和助力壳体,主壳体内设置有第一传动组件;助力壳体设置有安装腔,安装腔内设置有第二传动组件,第二传动组件与第一传动组件传动连接;助力壳体还包括隔离单元,隔离单元能够将第二传动组件的油脂隔离在助力壳体内;汽车转向机构还包括密封单元,密封单元包括密封部和密封件;密封部包括分别设于助力壳体和主壳体的轴向端部的局部密封面;密封件设于密封部的径向内侧。本发明有效的防止第二传动组件的润滑油脂混入第一传动组件内,且防止主壳体和助力壳体的衔接部位漏油。
