The invention relates to the technical field of automobile suspensions, in particular to a suspension hydraulic spring cushion, a suspension and a vehicle, the suspension hydraulic spring cushion comprises a spring cushion body, a sealed hydraulic chamber is arranged in the spring cushion body, the hydraulic chamber is arranged along the lift of an end ring of a spring, and the hydraulic chamber is filled with a hydraulic medium; and the hydraulic medium consumes the vibration energy of the spring by flowing in the hydraulic chamber and adaptively adjusts the damping of the spring cushion. According to the suspension hydraulic spring cushion, the NVH and driving comfort of a whole vehicle can be improved, the suspension hydraulic spring cushion can be well attached to a spring end ring in the vehicle driving process, local abrasion of the spring cushion is reduced, the service life of the spring cushion is prolonged, and the driving abnormal sound risk caused after the spring cushion is worn through is eliminated.
本发明涉及汽车悬架技术领域,具体涉及一种悬架液压弹簧垫、悬架及车辆,悬架液压弹簧垫包括弹簧垫本体,弹簧垫本体内设置密封的液压腔室,液压腔室沿弹簧的端圈的升程布置,液压腔室内充满液压介质,液压介质通过在液压腔室内流动消耗弹簧的振动能量并自适应调节弹簧垫的阻尼。本发明的悬架液压弹簧垫能够提高整车NVH及驾驶的舒适性,并且在车辆行驶过程中能保持与弹簧端圈良好的贴合,减少弹簧垫的局部磨损,提高弹簧垫的使用寿命,消除弹簧垫磨穿后带来的行车异响风险。
