Full-automatic locking suspension device

The invention belongs to the field of multi-axle vehicles, and particularly relates to a full-automatic locking suspension device. The full-automatic locking suspension device comprises a damping valve and an inertia valve, wherein the damping valve comprises a first valve seat, a second valve seat, a valve rod, a spring and a valve sleeve; the inertia valve comprises a sliding block and a pre-pressing spring; the inertia valve is introduced into the damping valve, the working condition change is sensed by utilizing the sensitivity characteristic of the inertia valve to the acceleration, the damping function and the locking function are switched by shielding the opening degree of the damping valve, and the stability of the vehicle is improved. 本发明属于多轴车辆领域，具体涉及一种全自动闭锁悬挂装置，其包括：阻尼阀、惯性阀，阻尼阀包括第一阀座、第二阀座、阀杆、弹簧、阀套；惯性阀包括滑块、预压弹簧；阻尼阀内引入了惯性阀，利用惯性阀对加速度敏感特性来感应工况变化，通过遮挡阻尼阀开度实现阻尼功能与闭锁功能切换，提高车辆的稳定性。
