The invention discloses a vehicle suspension system capable of being accurately folded, unfolded and positioned. The system comprises an executing mechanism, a suspension assembly and a flow control module. The executing mechanism comprises a pull arm, a longitudinal arm assembly and a bearing wheel; the bearing wheel is mounted at the tail end of the longitudinal arm assembly and can rotate flexibly; the head end of the longitudinal arm assembly is fixedly installed on a hinge shaft, and the hinge shaft is installed on a vehicle body and can pivot. One end of the pull arm is fixedly connected with the hinge shaft; and an angle is formed between the pull arm and the longitudinal arm assembly. The suspension assembly is used for adjusting the trailing arm, and the flow control module accumulates pressure for a pressure accumulator of the suspension assembly. While different vehicle height requirements of land and water running working conditions are met, the height limit index can be met by accurately reducing the suspension height, namely, the bearing capacity of the vehicle is improved to the maximum extent while the index requirements are met through the suspension system. The device also has the advantages of simple structure, high reliability and good maintainability.

    本发明公开了一种可精确收放定位的车辆用悬挂系统,该系统包括执行机构、悬架组件、流量控制模块。所述的执行机构包括拉臂、纵臂总成和承重轮;承重轮安装在纵臂总成尾端,承重轮能灵活转动;纵臂总成首端固定安装在铰接轴上,铰接轴安装在车体上,铰接轴能够枢转;拉臂的一端与铰接轴固定连接;拉臂与纵臂总成之间具有角度。悬架组件用于调节纵臂,流量控制模块为悬架组件的蓄压器蓄压。本发明在达到陆地、水上行驶工况不同车高需求的同时,可通过精确降低悬挂高度,满足限高指标,即可通过本发明的悬挂系统实现指标要求的同时,极大限度的提高车辆承载能力。本发明还具有结构简单,可靠性高,维修性好的优点。
