The invention relates to a transverse stabilizer bar pull rod assembly with adjustable roll stiffness, which comprises an upper rod and a lower rod, wherein the upper end and the lower end of the upper rod are connected with a suspension and two buffer material installation sleeves respectively, polyurethane materials are fixed to the two buffer material installation sleeves, the upper end and thelower end of the lower rod are connected with a transverse stabilizer bar and a sleeve respectively, an end cover is installed on the sleeve structure, a self-lubricating bearing is installed in an inner hole, the upper rod, the two buffer material installation sleeves and two polyurethane materials are inserted into a cavity of the sleeve structure through the self-lubricating bearing. Startingfrom the angle of force transmission control of the transverse stabilizer bar and the suspension system, the split design is adopted, the structure is simple, implementation is easy, the effect of supporting and connecting the transverse stabilizer bar can be achieved, and when the roll angle of a vehicle body is small or wheels on the left side and the right side generate small-amplitude and frequent vertical relative displacement, the force transmission path of the transverse stabilizer bar is closed, and when the roll angle of the vehicle body is large, the force transmission path of the transverse stabilizer bar is opened, and the chassis stability and comfort are both considered.

    本发明涉及一种侧倾刚度可调横向稳定杆拉杆总成,包括上杆和下杆,上杆上下两端分别与悬架和两个缓冲材料安装套相连,两个缓冲材料安装套上固定聚氨酯材料,下杆上下两端分别与横向稳定杆和套筒相连,套筒结构上装有端盖,其内孔安装自润滑轴承,上杆、两个缓冲材料安装套、两个聚氨酯材料,经由自润滑轴承插入套筒结构腔体内。本发明从横向稳定杆与悬架系统力传递控制角度出发,采用分体式设计,结构简单,易于实现,既能起到支撑与连接横向稳定杆的作用,又可实现当车身侧倾角较小,或左右两侧车轮发生幅度不大且频繁的垂向相对位移时,横向稳定杆的力传递路径关闭,当车身侧倾角较大时,横向稳定杆的力传递路径开启,兼顾底盘稳定性与舒适性。
