The invention relates to a rear suspension structure of an unmanned drive-by-wire chassis. The rear suspension structure comprises a frame, a shock absorber assembly, a drive axle, a stabilizer bar, a connecting rod bracket, an upper connecting rod and a lower connecting rod, the frame is composed of a first vertical support, a second vertical support, a third vertical support, a transverse support, a first accessory, a first lining and a second lining which are connected in a welded mode. The shock absorber assembly consists of a pair of shock absorbers and a spring which are symmetrically distributed left and right, and is assembled between the frame and the connecting rod bracket; the stabilizer bar is arranged between the frame and the drive axle; the connecting rod supports are fixed to the drive axle in a bilateral symmetry mode, and the connecting rod supports, the shock absorber assemblies, the upper connecting rods and the lower connecting rods form a four-connecting-rod mechanism. The functions of suspension supporting, wheel up-and-down jumping damping, integrated installation of the driving module, transverse stable adjustment and the like are achieved, installation of the driving motor is simplified, the cost is reduced, braking nodding and acceleration rear contusion are restrained, and the stability of the posture of a vehicle body is kept.

    本发明涉及一种无人驾驶线控底盘的后悬架结构,包括车架,减震器总成,驱动桥,稳定杆,连杆支架,上连杆,下连杆;车架由焊接连接的第一垂向支架、第二垂向支架、第三垂向支架、横向支架、第一附件、第一衬套和第二衬套组成;减震器总成由左右对称分布的一对减震器、弹簧组成,组装在车架和连杆支架之间;稳定杆布置在车架和驱动桥之间;连杆支架左右对称固定在驱动桥上,连杆支架、减震器总成、上连杆和下连杆形成四连杆机构。本发明实现了悬架支撑、车轮上下跳动减震、集成式安装驱动模块及横向稳定调节等功能,简化了驱动电机的安装,降低成本,抑制了制动点头和加速后挫,保持了车身姿态的稳定性。
