Problems solved by technology

[0003] Chinese patent CN201410555080.7 discloses a parallel hydraulic electric energy-fed suspension system, which can partially convert the vibration energy caused by the unevenness of the road surface into electric energy, but when the oil passes through the hydraulic motor to do work, the system does not affect the oil Liquid return route to control
The oil is preferentially returned to the hydraulic cylinder cavity with lower pressure, so this system may increase the stroke difference between the left and right suspensions, which is not conducive to the handling stability of the vehicle

Abstract

The invention patent relates to a hydraulically interconnected suspension that can recover vibration energy. Including hydraulic cylinders, connecting pipelines, hydraulic rectifier bridges, accumulators, hydraulic motors, solenoid valves, and electronic control units. By connecting the hydraulic cylinders in the rear suspension hydraulically interconnected suspension in reverse series, that is, the upper chamber of the left hydraulic cylinder is connected to the lower chamber on the right, and the lower chamber on the left is connected to the upper chamber on the right. When the left and right wheels are jumping, the liquid interaction between the connecting pipelines can balance the loads on the wheels on both sides, and the anti-rolling effect can be achieved; at the same time, the flow of oil in the pipeline drives the hydraulic motor to rotate in one direction, and the hydraulic motor drives the generator to generate electricity , the generated electric energy is stored in the battery through the charging circuit, so that the hydraulic interconnected energy-feeding suspension achieves the purpose of recovering vibration energy.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to a hydraulic interconnected suspension. technical background [0002] Interconnected suspension refers to a suspension system that associates the motion of the originally independent vehicle wheels according to the established mechanism through a mechanical or hydraulic structure, which can transmit the motion of a single wheel to other wheels and cause corresponding changes in the spring force , so that the handling performance of the vehicle can be greatly improved on the premise that the ride comfort does not deteriorate. At the same time, the hydraulic-electric energy-feeding shock absorber is a set of mechanical-electrical-hydraulic coupling system. The proposal of this system provides a hydraulic transmission type vibration energy recovery scheme, which expands the research ideas in the field of vehicle vibration energy recovery. . [0003] Chinese patent CN2014...
