The invention belongs to the technical field of automobile suspension devices, and relates to a suspension structure, a double-wheel steering drive axle and an automobile, the suspension structure comprises a drive motor mounting steering seat, an upper thrust plate, a lower thrust plate, an air spring and a torsion rocker arm, the upper end of the air spring is fixed on an automobile frame, and the lower end of the air spring is fixed on the lower thrust plate; the upper end, provided with the steering base, of the driving motor can be rotationally connected to the rear vertical part of the torsion rocker arm through a rotating component. According to the suspension structure, the air spring is integrated between the upper thrust plate and the lower thrust plate, the structure is compact, space is saved, the space, occupied by a double-wheel steering drive axle, in the running direction (the X-axis direction) of the interior of an automobile can be greatly saved, the large-wheelbase arrangement requirement of a commercial vehicle can be met, and the space in the automobile can be optimized. Meanwhile, the torsion rocker arm is of a square structure defined by the front vertical part, the upper connecting part, the rear vertical part and the lower connecting part, the structure is compact, the occupied space is saved, and the overall rigidity is high.
本发明属于汽车悬架装置技术领域,涉及一种悬架结构、双车轮转向驱动桥及汽车,包括驱动电机安装转向座、上推力板、下推力板、空气弹簧及扭力摇臂,所述空气弹簧的上端固定在车架上,所述空气弹簧的下端固定在所述下推力板上;驱动电机安装转向座的上端可以通过一旋转部件转动地连接在扭力摇臂的后竖直部上。本申请的悬架结构,将空气弹簧整合到上、下推力板之间,结构紧凑,节省空间,可大大节省双车轮转向驱动桥占据的汽车内部的行驶方向(X轴方向)的空间,能够满足商用车大轴距的布置需求,可以优化车内空间。同时,扭力摇臂为由前竖直部、上连接部、后竖直部及下连接部围合形成一“口”字形结构,结构紧凑,节省占用空间,整体刚性高。
