Problems solved by technology

The spring has the characteristics of phase lag and "pass low frequency, block high frequency", and the inertial accumulator has the characteristics of phase advance and "pass high frequency, block low frequency". The impact and vibration caused by high speed are buffered and attenuated; due to the redundant constraints of the four-wheeled vehicle, the over-positioning is caused. On the rough road, the body will bear a large torsional load, which is not conducive to the service life of the parts of the body; the traditional suspensio

Abstract

The invention discloses a hydraulic interconnection type energy storage and feedback suspension and a using method thereof. An upper cavity and a lower cavity of a left hydraulic cylinder and an upper cavity and a lower cavity of a right hydraulic cylinder of the energy storage suspension are interconnected in the forward direction through an energy feedback hydraulic pipeline. When an automobile travels to a common road surface, the riding comfort is considered first, an interconnection energy feedback loop is closed by switching work oil ports of electromagnetic valves, and the suspension is a hydraulic energy storage suspension. When the automobile travels to a rugged road surface, the work oil ports of the electromagnetic valves are switched, the interconnection energy feedback loop is opened, excessive constraints are reduced, and thus the purpose of removing torsion loads of an automobile body is achieved. Meanwhile, reciprocating flow energy of the left hydraulic cylinder and the right hydraulic cylinder is recycled through the energy feedback hydraulic pipeline, and the energy is converted into electric energy to be used by automobile electrical equipment. The working performance of the suspension under multiple working conditions is effectively improved, energy recycling is achieved, and wide using prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle suspensions, in particular to a hydraulically interconnected energy storage and energy feeding suspension and its use method. Background technique [0002] The proposal of the three-element ISD (inertia-spring-damping) suspension breaks through the limitations of the traditional electromechanical similarity theory and realizes the strict one-to-one correspondence between "mass-spring-damping" and "capacitance-inductance-resistance". The spring has the characteristics of phase lag and "pass low frequency, block high frequency", and the inertial accumulator has the characteristics of phase advance and "pass high frequency, block low frequency". buffer and attenuate the shock and vibration caused by high speed; the four-wheel vehicle has redundant constraints, resulting in over-positioning, and on rough roads, the body will bear a large torsional load, which is not conducive to the service life of th...
