Abstract
An active control anti-yaw damper () is provided. When a piston () of the active control anti-yaw damper () reciprocates inside a hydraulic cylinder (), an interior of the hydraulic cylinder () is divided into two cylinder blocks (PA, PB) which communicate with an oil reservoir through two main oil lines respectively to form a primary loop between the hydraulic cylinder () and the oil reservoir; a reversing valve (PV) is installed between the two main oil lines and the oil reservoir and is configured to change a flow direction of the primary loop when the active control anti-yaw damper () is in an active mode and adjust a displacement of the piston () within the hydraulic cylinder ().
