The invention discloses a reversely-installed axle and a vehicle chassis provided with the reversely-installed axle, the reversely-installed axle comprises an axle body, two sets of guide arms and a connecting piece, the axle body comprises a center beam and wheel edge hub components arranged at the two ends of the center beam, and the center beam is installed above the two sets of guide arms in a supported mode; the connecting piece comprises an upper bearing piece, a lower fixing piece, a U-shaped bolt and an adaptive nut of the U-shaped bolt, the upper bearing piece is arranged between the center beam and the guide arm, the lower fixing piece is arranged below the guide arm and clamps the guide arm together with the upper bearing piece, and the U-shaped bolt clamps the center beam and sequentially penetrates through the upper bearing piece and the lower fixing piece downwards. And relative fixation is carried out through an adaptive nut. And the four groups of reversely-mounted axle mechanisms are assembled below the frame mechanism of the vehicle chassis through suspension mechanisms. The structure is simple, the height of the whole frame is reduced through reverse assembly matching of the guide arms and the axle center beam, and therefore the cargo loading capacity of a vehicle is increased, and the transportation cost is reduced.
本发明公开了一种反装式车桥及安装有该车桥的车辆底盘,其中反装式车桥包括车桥主体、两组导向臂以及连接件,所述车桥主体包括中心梁及设置于中心梁两端部的轮边轮毂部件,其中中心梁担装于两组导向臂上方;所述连接件包括上承托件、下固定件以及U型螺栓及其适配螺母,上承托件置于中心梁与导向臂之间,下固定件置于导向臂下方,并与上承托件共同夹持导向臂,所述U型螺栓夹套中心梁并向下依次穿过上承托件和下固定件,通过适配螺母进行相对固定。所述车辆底盘的车架机构下方通过悬架机构装配有上述四组反装式车桥机构。本发明结构简单,运用导向臂与车桥中心梁的反装配合,降低了整体车架高度,从而增加了车辆的货物装载量,降低了运输成本。
