The oil inlet (P) is connected to the oil tank (210), the first oil outlet (A) is connected to the rod chamber (111), the second oil outlet (B) is connected to the rodless chamber (112), and the return oil outlet (T) is connected to the oil tank (210). The reversing valve (250) includes a first working position, a second working position, and an intermediate position; In the first working position, the oil inlet (P) is connected to the second oil outlet (B), and the first oil outlet (A) is connected to the return oil outlet (T). In the second working position, the oil inlet (P) is connected to the first oil outlet (A), and the second oil outlet (B) is connected to the return oil outlet (T). In the intermediate position, the valve core (251) blocks the first oil outlet (A) and the second oil outlet (B). The controller is used to control the directional valve (250) connected to the compressed shock absorber (100) to the first operating position and the directional valve (250) connected to the stretched shock absorber (100) to the second operating position when the vehicle has a tendency to roll.

5. The roll-prevention system of claim 4, wherein The oil tank (210) and the oil inlet (P) are connected by an oil inlet pipe (260). The regulating mechanism also includes an overflow pipe (280) and an overflow valve (281) disposed on the overflow pipe (280). One end of the overflow pipe (280) is connected to the oil inlet pipe (260) and the other end is connected to the oil tank (210).
