The invention provides a four-hinge-guided automobile suspension mechanism capable of carrying out crabwalk steering. The mechanism is designed for designing a suspension capable of achieving four-wheel independent driving and independent steering for an automobile. More importantly, by means of the suspension mechanism, the automobile can achieve 90-degree steering and can further achieve in-situ direct steering. The suspension mechanism mainly comprises a suspension supporting arm and a suspension guide mechanism. The two ends of the supporting arm are connected with the two ends of the suspension through side flanges and a suspension lower suspension flange respectively. Two sleeves are arranged on an upper suspension flange and the lower suspension flange. A spring is installed on the inner side of each sleeve. A vibration reducer is sleeved in each spring. The guide mechanism comprises four hinge mechanisms. Each hinge mechanism comprises five parts including an upper sheet, a lower sheet, hinged supports, rotating pins and copper sleeves. The four hinge mechanisms are connected with the upper suspension flange and the lower suspension flange through bolts into a whole. When the four-hinge-guided automobile suspension mechanism needs to be installed on the finished automobile, a worker only needs to connect the upper suspension flange with a shaft coupler stretching out of a steering motor. The suspension mechanism has the beneficial effects that the independent wheel steering angle range of wheels is wide, assembling is convenient, and cost is low.
