Energy-feedback suspension system

Abstract

The invention discloses an energy-feedback suspension system. A piston rod is axially installed inside a dustproof hood of the energy-feedback suspension system; the upper part of the piston rod is ofa screw structure; the outer circumference of the screw structure is sleeved with a screw nut; stop blocks are correspondingly installed at the upper and lower ends of the screw nut; a permanent magnetic iron frame is installed at the outer circumference of the screw nut; a permanent magnet is installed inside the permanent magnetic iron frame; a coil winding is installed between the permanent magnetic iron frame and the screw nut; an outer ring of an oil storage bucket is fixedly connected with a bracket cylinder used for supporting the permanent magnetic iron frame; a piston is installed atthe bottom end of the piston rod; the piston is provided with a rebound valve and a flow valve; an end plate is installed at the lower part of a working cylinder; a compression valve and a compensation valve are installed on the end plate; the compression valve is positioned under the rebound valve; and the compensation valve is positioned under the flow valve. The energy-feedback suspension system solves the problems that an energy-feedback suspension of the prior art is incapable of efficiently recycling vibration energy and meanwhile the vibration isolation performance is not good; the energy-feedback suspension system provided by the invention can realize efficient recycle of the vibration energy of the suspension, also has excellent vibration isolation performance and improves the operation stability and the running smoothness of a vehicle.

Description

technical field [0001] The invention relates to an energy-feeding suspension system, which belongs to the technical field of automobile suspension. Background technique [0002] In recent years, domestic and foreign scholars have not only focused on improving the vibration isolation performance of the suspension, but also paid more attention to the energy recovery of the suspension during the vibration process. Under this background, the concept of energy-feeding suspension came into being. [0003] The "energy feed" in the energy feed suspension system refers to the concept of energy recovery, which can not only effectively block the transmission of vibration, but also recover the energy in the vibration process. However, the research on the energy-feeding suspension is still in the stage of theoretical research and experimental testing, and no energy-feeding suspension has been put into commercial market operation. In particular, the electromagnetic energy-feeding suspens...
