The invention discloses an autonomous intelligent self-energy-supply
active suspension adopting a double-head oil cylinder and a working method, and belongs to the field of automobiles, the autonomous intelligent self-energy-supply
active suspension comprises a traditional vibration reduction structure and an anti-
resonance vibration reduction structure, the anti-
resonance vibration reduction structure is provided with the double-head oil cylinder, and the double-head oil cylinder is composed of a second oil cylinder arranged up and down and a second
piston with
piston rods at the upper end and the lower end; the upper portion of an upper oil cavity of the second oil cylinder is sequentially connected with an
inerter spiral
pipe, an
intelligent control switch and the lower portion of a lower oil cavity of the second oil cylinder through a hydraulic pipeline, and the two ends of the
intelligent control switch are connected with a normally-closed
electromagnetic valve which is closed in a delayed mode in parallel. The
intelligent control switch automatically changes the equal-inertial-
capacity value and the equal-damping value of the anti-
resonance vibration reduction structure along with changes of the vibration frequency of the automobile, when the vibration frequency of the automobile is low, large equal-inertial-capacity and equal-damping are provided to improve the
driving safety, and when the vibration frequency of the automobile is high, small equal-inertial-capacity and equal-damping are provided to improve the riding comfort.
