The invention discloses a suspension system based on an active steering lifting axle, a control method and a vehicle, the suspension system comprises the active steering lifting axle, a mounting support assembly, an air supply mechanism and a control mechanism, the mounting support assembly comprises a front air bag assembly, a rear air bag assembly, a turnover assembly and a connecting arm assembly, the connecting arm assembly is fixed to the top of the active steering lifting bridge, one end of the connecting arm assembly is fixedly connected with the bottom of the rear air bag assembly, the other end of the connecting arm assembly is hinged to the overturning assemblies, the overturning assemblies are fixedly connected to the two sides of the front air bag assembly, and the top of the front air bag assembly and the top of the rear air bag assembly are fixedly connected with a vehicle frame. On the basis that the problem of the minimum turning diameter of a long-wheelbase vehicle type is solved, the active steering lifting axle can be retracted and put down according to working conditions, and the technical problems that in the prior art, the contact consistency of a suspension and the ground is poor, the service life of parts is shortened due to generated impact stress, and the comfort of the whole vehicle is affected are solved.
本发明公开一种基于主动转向举升桥的悬架系统、控制方法及车辆,所述悬架系统包括主动转向举升桥、安装支架总成、供气机构和控制机构,所述安装支架总成包括前气囊组件、后气囊组件、翻转组件及连接臂组件,所述连接臂组件固定在所述主动转向举升桥顶部,且一端与所述后气囊组件底部固定连接,另一端与所述翻转组件铰接,所述翻转组件固定连接在所述前气囊组件两侧,所述前气囊组件和后气囊组件顶部分别与车架固定连接。本发明能够在解决长轴距车型最小转弯直径问题的基础上使得主动转向举升桥可根据工况进行收回和放下,解决了现有技术中悬架与地面接触的一致性较差,产生的冲击应力会减小零件寿命以及影响整车舒适性的技术问题。
