The invention relates to the technical field of vehicles, in particular to a liftable axle structure of a new energy truck. The liftable axle structure comprises a truck bottom plate, an adjustable connecting arm, a balance plate, an axle rod and a damping buffer assembly. The damping buffer assembly comprises a first compression cylinder, a first piston rod, a second compression cylinder, a connecting base, a second piston rod and a third compression cylinder. According to the liftable axle structure of the new energy truck, the stability of the truck running on a severe road surface can be guaranteed, the damping buffer forces in the two directions are used for reducing the influence on the axle stability due to the change of the adhesive force of tires, and compared with a traditional mode of increasing the axle weight, the stability of the axle structure can be guaranteed, the speed, the load, the energy consumption and the like of the truck cannot be affected, and the use requirements of the truck under the condition that the running road surface condition is severe are particularly met.

    本发明涉及车辆技术领域,尤其涉及一种新能源卡车可升降车桥结构,包括车底板、可调节连接臂、平衡板、车桥桥杆和阻尼缓冲组件;所述阻尼缓冲组件包括第一压缩筒、第一活塞杆、第二压缩筒、连接座、第二活塞杆和第三压缩筒。本发明提供的新能源卡车可升降车桥结构,可以保证卡车在较为恶劣的路面上行驶时的平稳性,利用两个方向上的阻尼缓冲力降低由于轮胎的附着力忽大忽小变化对车桥稳定性的影响,相较于传统的增加车桥重量的方式,既能保证车桥结构的稳定性,又不会对卡车的速度、载重以及能耗等产生影响,特别满足卡车在行驶路面情况较为恶劣的情况下的使用要求。
