The invention relates to the field of vehicles, and discloses a single-arm independent suspension, a multi-axle steering vehicle chassis and a vehicle, the single-arm independent suspension comprises a control arm (1) and a suspension oil cylinder (2), one end of the control arm (1) is pivotally connected or spherically hinged to a steering knuckle (3), and the other end of the control arm (1) is arranged to be relatively pivotally connected to a vehicle frame; the control arm (1) and the frame are connected so that an angle theta formed by a pivoting axis between the control arm (1) and the frame and an XZ plane of a vehicle coordinate system is more than 0 and less than 90 degrees; the bottom end of the suspension oil cylinder (2) is connected to the steering knuckle (3) or the control arm (1), and the other end of the suspension oil cylinder (2) is used for being connected to the frame in a spherical hinge mode. When passing through an undulating road surface, stretching and retracting of a suspension oil cylinder and undulating of wheels in a vehicle chassis adopting the suspension arm type independent suspension cannot cause remarkable changes of a kingpin positioning angle and a wheel track, and therefore tire abrasion is relieved.
本发明涉及车辆领域,公开了一种单臂式独立悬架、多桥转向车辆底盘和车辆,所述单臂式独立悬架包括控制臂(1)和悬架油缸(2),所述控制臂(1)的一端枢转连接或球铰连接于转向节(3),另一端设置为能够相对枢转地连接至车架,并连接为使得所述控制臂(1)和该车架之间的枢转轴线与车辆坐标系的XZ平面所成的角θ满足0<θ<90°;所述悬架油缸(2)的底端连接至所述转向节(3)或所述控制臂(1),另一端用于球铰连接至所述车架。在经过起伏路面时,采用本发明悬单臂式独立悬架的车辆底盘中悬架油缸的伸缩和车轮的起伏不会导致主销定位角和轮距的显著变化,由此减轻轮胎磨损。
