摘要： A vehicle differential unit in which an input or drive pinion is mounted on a shaft which is supported on two axially spaced bearing assemblies carried by a housing which encloses the unit. The housing is provided with first and second apertures, the second aperture, which is provided with a detachable cover, being of sufficient size to pass the drive pinion and the first aperture not allowing the passage therethrough of the drive pinion. A first bearing assembly, which is supported in the first aperture, supports a first end portion of the shaft with which a vehicle drive shaft is normally associated and a second bearing assembly, located on the other side of the drive pinion from the first bearing assembly, supports a second end portion of the shaft which is located within the housing adjacent a crown wheel of the differential unit. The second bearing assembly is mounted on a bearing support which is separate from the housing and is secured to an abutment surface on the housing by releasable means so that the bearing support can be inserted into the housing through the second aperture and, after the first end portion of the pinion shaft has been received in the first bearing assembly, the second bearing assembly can be located on the second end portion of the shaft and the releasable means then engaged to secure the bearing support to the housing.

摘要翻译： 一种车辆差速器单元，其中输入或驱动小齿轮安装在轴上，所述轴被支撑在由围绕所述单元的壳体承载的两个轴向间隔开的轴承组件上。 壳体设置有第一和第二孔，第二孔具有可拆卸盖，其尺寸足以使驱动小齿轮和第一孔不允许驱动小齿轮通过。 支撑在第一孔中的第一轴承组件支撑轴的第一端部，车辆驱动轴通常与该第一端部相关联;以及第二轴承组件，其位于驱动小齿轮的另一侧，从第一轴承组件 支撑轴的第二端部，该第二端部位于邻近差速单元的冠轮的壳体内。 第二轴承组件安装在与壳体分离的轴承支撑件上，并且通过可释放的装置固定到壳体上的邻接表面，使得轴承支撑件可以通过第二孔插入到壳体中，并且在第一端 小齿轮轴的部分已经被容纳在第一轴承组件中，第二轴承组件可以位于轴的第二端部上，然后可释放装置接合以将轴承支撑件固定到壳体。
