The invention relates to an integrated symmetrical supporting single-swing-arm suspension wheel-side electric driving system. The system comprises two single-swing-arm suspension wheel-side electric driving modules which are symmetrically arranged. Each single-swing-arm suspension wheel-side electric driving module comprises a frame (1), wheels, a reduction gearbox (4) and a single-trailing-arm swing arm (17). Output shafts (10) of the reduction gearboxes (4) are connected with half shaft sleeves (16) through hub bearings (8). The reduction gearboxes (4) are connected with the frames (1) through the single-trailing-arm swing arms (17). The half shaft sleeves (16), the single-trailing-arm swing arms (17) and the reduction gearboxes (4) are integrally and fixedly connected. Shock absorbers (15) are longitudinally arranged between the reduction gearboxes (4) and the frames (1). A torsion bar (7) is horizontally connected between the reduction gearboxes (4) in the two single trailing arm suspension wheel-side electric driving modules. Compared with the prior art, the system has the advantages of good stability, high roll stiffness and the like.

    本发明涉及一种一体化对称支撑单摆臂悬架轮边电驱动系统,包括对称设置的2个单摆臂悬架轮边电驱动模块,每个单摆臂悬架轮边电驱动模块包括车架(1)、车轮、减速箱(4)和单纵臂摆臂(17),所述的减速箱(4)的输出轴(10)通过轮毂轴承(8)与半轴套(16)连接,所述的减速箱(4)通过单纵臂摆臂(17)与车架(1)连接,所述的半轴套(16)、单纵臂摆臂(17)以及减速箱(4)一体化固定连接,所述的减速箱(4)与车架(1)之间纵向设有减震器(15),所述的2个单摆臂悬架轮边电驱动模块中各自的减速箱(4)之间水平连接有扭杆(7)。与现有技术相比,本发明具有平稳性好、侧倾刚度高等优点。
