The invention relates to an air suspension system and a heavy truck. The air suspension system is located between a frame of the vehicle and a middle axle and a rear axle of the vehicle and comprises a balance beam, a first end of the balance beam is connected with the middle axle of the vehicle, a second end of the balance beam is connected with the rear axle of the vehicle, and the balance beam is used for balancing loads of the middle axle and the rear axle; the guide arm is located between the balance beam and a frame of the vehicle, the middle of the guide arm is connected with the middle of the balance beam, and the guide arm is connected with the frame through an elastic assembly; the guide arm is used for transmitting the load of the frame to the balance beam; and the elastic assembly is used for transmitting the load between the frame and the balance beam. By the adoption of the air suspension system, it can be guaranteed that loads of the middle axle and the rear axle are always kept equal in the movement process of the suspension, and real-time balance of the loads of the middle axle and the rear axle is guaranteed; meanwhile, the vehicle frame is prevented from bearing torque in the suspension movement process, the torsional stress of the vehicle frame is reduced, and then the comfort and stability of the vehicle in the running process are improved.

    本申请涉及一种空气悬架系统及重型卡车。该空气悬架系统位于车辆的车架与车辆的中桥和后桥之间,该系统包括:均衡梁,均衡梁的第一端与车辆的中桥连接,均衡梁的第二端与车辆的后桥连接,用于平衡中桥和后桥的载荷;导向臂,位于均衡梁与车辆的车架之间,导向臂的中部与均衡梁的中部连接,且导向臂通过弹性组件与车架连接;导向臂用于将车架的载荷传递给均衡梁;弹性组件,用于传递车架与均衡梁之间的载荷。采用本空气悬架系统能够确保在悬架运动过程中中桥和后桥的载荷始终保持相等,保证了中桥和后桥的载荷实时平衡;同时避免了车架在悬架运动过程中承受扭矩,减少了车架的扭转应力,进而提升车辆行驶中的舒适性和稳定性。
