Claims

[Scope of Claim for Utility Model Registration] (1) A double-acting fluid pressure cylinder is interposed between each wheel of the vehicle and the vehicle body, and for the left and right double-acting fluid pressure cylinders, the upper pressure chamber of one is connected to the other. A piping system is constructed by communicating the lower pressure chamber of the front and rear cylinders with each other through cross piping, and connecting the left and right sides of the front and rear double-acting fluid pressure cylinders with each other through fluid piping, and connecting the piping system to the power steering system. When turning, the double-acting fluid cylinder on the outer wheel side is extended and the double-acting fluid cylinder on the inner wheel side is contracted. This is an active suspension system that is characterized by: (2) The control valve linked to the control valve of the power steering device is composed of a four-way control valve whose opening degree changes depending on the steering force, and the operating side port of the four-way control valve is connected to the control valve through a variable throttle valve. 2. The active suspension according to claim 1, wherein the variable throttle valve is controlled in accordance with vehicle speed.
