The invention discloses a trailing arm type rear independent suspension system which comprises a trailing arm, the trailing arm is connected with a shock absorber assembly through a shock absorber lower support, and a spiral spring is arranged on the trailing arm through a spring lower tray; the dragging arm is composed of a U-shaped arm and a linear arm, a first lining and a second lining are movably arranged on the U-shaped arm, and a sleeve fixedly connected with the hub shaft is arranged at the end, away from the U-shaped arm, of the linear arm. The invention has the following advantages: the form is an independent suspension which can be used as a rear suspension of a front wheel drive vehicle; the structure is simple, a ground bottom plate of a vehicle body can be flat, and enough arrangement space is provided for an oil tank and a spare tire between the trailing arms on the two sides; for a logistics vehicle, the cargo box can be arranged to be lower, the volume of the cargo box is increased, meanwhile, the distance between the cargo box and the ground is reduced, the cargo loading and unloading efficiency is improved, the labor intensity of workers is reduced, and the low-floor concept and the cargo box lifting function can be completely achieved.

    本发明公开了一种拖曳臂式后独立悬架系统,包括拖曳臂,所述拖曳臂通过减震器下支架连接设置有减震器总成,所述拖曳臂上通过弹簧下托盘设置有螺旋弹簧;所述的拖拽臂由U型臂和直线臂组成,所述U型臂上活动设置有第一衬套和第二衬套,所述直线臂远离U型臂的端部设置有与轮毂轴固定连接的套管。本发明具有如下优点:形式为独立悬架,可用于前轮驱动车辆的后悬架;结构简单,可使车身地底板平整,而且两侧拖曳臂间为油箱和备胎提供足够的布置空间;对于物流车,可以将货箱布置的更低,在增大货箱容积的同时,使得货箱与地面的距离减少,增加货物装卸效率,减小工人劳动强度,能够完全实现“低地板”概念和货箱升降的功能。
