The invention relates to a truck wheel rim structure which comprises a hub and an axle housing, a hub outer bearing and a hub inner bearing are arranged between the hub and the axle housing, the hub inner bearing comprises a hub inner bearing inner ring matched with the axle housing, and the hub outer bearing comprises a hub outer bearing inner ring matched with the axle housing, an outer first extending part is arranged on an inner ring of the hub inner bearing, an inner ring of the hub outer bearing is provided with an inward second extending part, and the first extending part is in contactwith the second extending part. The hub inner bearing inner ring and the hub outer bearing inner ring are oppositely provided with extending parts, and the second extending parts abut against the first extending parts, so that the relative positions of the hub outer bearing and the hub inner bearing are fixed. When the hub is overhauled and the hub outer bearing is reinstalled, only the extendingpart of the hub outer bearing needs to be aligned with the extending part of the hub outer bearing again.

    本发明涉及一种载货汽车轮边结构,包括轮毂、桥壳,轮毂与桥壳之间设有轮毂外轴承和轮毂内轴承,所述轮毂内轴承包括与桥壳配合的轮毂内轴承内圈,所述轮毂外轴承包括与桥壳配合的轮毂外轴承内圈,所述轮毂内轴承内圈设置外的第一延伸部,所述轮毂外轴承内圈向内的第二延伸部,所述第一延伸部与第二延伸部相接触。轮毂内轴承内圈和轮毂外轴承内圈相向设置延伸部,且第二延伸部抵住第一延伸部,因此轮毂外轴承与轮毂内轴承的相对位置固定。在对轮毂进行检修重新安装轮毂外轴承时,只需将轮毂外轴承的延伸部与轮毂外轴承的延伸部重新对位即可。
