The invention discloses an equal-damping equal-
inerter oil way of a single-head oil cylinder of a self-powered
active suspension and a working method of the equal-damping equal-
inerter oil way in the field of automobiles, and the equal-damping equal-
inerter oil way is composed of a traditional vibration reduction oil way and an anti-
resonance vibration reduction oil way, and the traditional vibration reduction oil way is connected between a
piston rod cavity and a rodless cavity of a first oil cylinder in series; a first damping tube, a first oil gas storage chamber and a second damping tube are sequentially connected between a rodless cavity and a
piston rod cavity of the first oil cylinder; a third one-way valve is connected in parallel between two ends of the second damping tube; an anti-
resonance vibration reduction oil way is connected between a
piston rod cavity and a rodless cavity of a second oil cylinder in series, a second inerter spiral
pipe, a second oil gas storage chamber, a first inerter spiral
pipe and an
electromagnetic valve are sequentially connected between the
piston rod cavity and the rodless cavity of the second oil cylinder, and the two ends, connected with the second oil gas storage chamber in series, of the second inerter spiral
pipe are connected with an eighth one-way valve in parallel. And third damping pipes are connected in parallel to the two ends of the
electromagnetic valve. The anti-
resonance vibration reduction structure can maintain damping stability provided by a traditional vibration reduction structure, and can maintain inerter stability provided by the anti-
resonance vibration reduction structure at the same time.
