The invention provides a trailing arm type independent suspension. The suspension comprises an auxiliary frame and two longitudinal arm assemblies which are arranged on the two sides of the auxiliaryframe respectively, and each longitudinal arm assembly is provided with a longitudinal arm body, a hub support unit, a vehicle body connecting unit and a spring support, the hub support unit and the vehicle body connecting unit are connected to the two ends of the longitudinal arm body respectively, and the spring support is arranged between the hub support unit and the vehicle body connecting unit and fixedly connected to one side of the longitudinal arm body. The suspension further comprises a stabilizer bar which is arranged on the auxiliary frame, the two ends of the stabilizer bar are respectively connected with stabilizer bar connecting rods in a spherical hinge mode, and the upper control arm, the lower control arm, the shock absorber and the spiral spring are respectively arrangedcorresponding to the longitudinal arm assemblies on the two sides. According to the trailing arm type independent suspension, the mounting parts are integrated on the hub support unit in the trailingarm assembly, and the spring support is arranged, so that mounting positions can be provided for components such as a spiral spring, a shock absorber, a stabilizer bar connecting rod and a hub bearing, the overall structure of the suspension can be simple, and the weight and the cost of the suspension can be reduced.
本发明提供了一种纵臂式独立悬架,其包括副车架,分设于副车架两侧的两个纵臂总成,所述纵臂总成具有纵臂主体,于纵臂主体的两端分别连接的轮毂支架单元和车身连接单元,以及于轮毂支架单元和车身连接单元之间、固连在纵臂主体的一侧的弹簧支座;还包括装设在副车架上且两端分别球铰连接有稳定杆连接杆的稳定杆,以及对应于两侧的纵臂总成分别设有一个的上控制臂下控制臂和减振器与螺旋簧。本发明的纵臂式独立悬架通过于纵臂总成中的轮毂支架单元上集成各安装部,以及设置弹簧支座,可为螺旋簧、减振器、稳定杆连接杆及轮毂轴承等构件提供安装位,以此可使得悬架整体结构简单,并有利于悬架重量及成本的降低。
