The invention discloses a suspension system, a vehicle chassis and a heavy truck, relates to the field of vehicles, and aims to realize rigidity self-adaptive adjustment of the suspension system. The suspension system comprises a frame, a plurality of axles, a plurality of oil cylinders and an energy accumulator assembly. The axles are separately arranged; and at least one oil cylinder is arranged between the frame and each axle. The energy accumulator assembly comprises a plurality of energy accumulators which are arranged in parallel, and the initial gas pressures of the energy accumulators are different; at least one oil cylinder is correspondingly connected with the energy accumulator assembly. According to the suspension system provided by the technical scheme, the energy accumulator assembly is installed between the rodless cavity and the rod cavity of the oil cylinder, the energy accumulator assembly comprises the multiple energy accumulators, and under different working conditions, the number of the energy accumulators participating in work is different, so that the rigidity of the suspension system is changed. According to the bearing condition of the vehicle, the number of the energy accumulators participating in work is automatically adjusted, manual intervention is not needed, electric control is not needed, and the automation degree is high.

    本发明公开了一种悬架系统、车辆底盘以及重型卡车,涉及车辆领域,用以实现悬架系统的刚度自适应调节。悬架系统包括车架、多个车桥、多个油缸以及蓄能器组件。各个车桥分开布置;车架与每个车桥之间均安装有至少一个油缸。蓄能器组件包括多个并联设置的蓄能器,且各个蓄能器的初始气体压力不相同;至少存在一个油缸对应连接蓄能器组件。上述技术方案提供的悬架系统,通过在油缸的无杆腔和有杆腔之间安装蓄能器组件,且蓄能器组件包括多个蓄能器,在不同工况下,参与工作的蓄能器的数量是不相同的,这就使得悬架系统的刚度发生改变。根据车辆的承载情况,参与工作的蓄能器数量自动调节,无需人工干预,无需电控,自动化程度高。
