The invention provides a dynamic rigidity high-low switchable anti-snaking shock absorber and a control system thereof.The shock absorber comprises three cavities, namely a compression cavity, a stretching cavity and an oil storage cavity, a first one-way valve (1), a first damping valve (1) and a first pressure release valve (1) are arranged between the stretching cavity and the oil storage cavity, and a second one-way valve (2) is arranged between the first damping valve (1) and the first pressure release valve (1); a second one-way valve (2), a second damping valve (2) and a second pressure release valve (2) are arranged between the compression cavity and the oil storage cavity, the compression cavity and the stretching cavity are separated by a piston, and the oil flowing direction between the compression cavity and the stretching cavity is determined by a reversing valve and a third one-way valve (3). The invention further designs a control system of the anti-snaking shock absorber with the high and low dynamic stiffness switchable, the system comprises a controller, a data collector and the anti-snaking shock absorber with the high and low dynamic stiffness switchable, and the data collector comprises a framework transverse acceleration sensor and a vehicle body transverse acceleration sensor. And the data collector is connected with the signal input end of the controller.

    本发明提供了一种动态刚度可高低切换式抗蛇行减振器及其控制系统,所述减振器包括三个腔室,即压缩腔、拉伸腔以及储油腔,拉伸腔与储油腔之间设置有第一单向阀(1)、第一阻尼阀(1)和第一泄压阀(1),压缩腔与储油腔之间设置有第二单向阀(2)、第二阻尼阀(2)和第二泄压阀(2),压缩腔和拉伸腔由活塞隔开,压缩腔和拉伸腔之间油液流动方向由换向阀和第三单向阀(3)决定。本发明还设计了一种动态刚度可高低切换式抗蛇行减振器的控制系统,该系统包括控制器、数据采集器以及如上所述的动态刚度可高低切换式抗蛇行减振器,数据采集器包括构架横向加速度传感器和车体横向加速度传感器,数据采集器与控制器的信号输入端连接。
