  • Publication number: 20220185054
    Abstract: A semi-active anti-yaw damper (100), a damping system and a vehicle are provided. When a piston (2) of the semi-active anti-yaw damper (100) reciprocates in the hydraulic cylinder (1), an interior of the hydraulic cylinder (1) is divided into two cylinder blocks (PA, PB). The semi-active anti-yaw damper (100) includes at least two parallel branches (B1, B2), the two ends of each of the parallel branches (B1, B2) are connected to the two cylinder blocks (PA, PB), respectively, and each of the parallel branches (B1, B2) is provided with an adjustable solenoid valve (PV), and the adjustable solenoid valve (PV) is configured to adjust a damping coefficient of the semi-active anti-yaw damper (100) when the semi-active anti-yaw damper (100) is in a semi-active mode.
