An active hydraulic interconnected energy-feeding suspension

Abstract

The invention provides an active hydraulic interconnected type energy reclaiming suspension. A left suspension and a right suspension are backwards and mutually connected through a connecting pipeline, and hydraulic motors are mounted on interconnected pipelines. Under a passive mode, oil fluid flows in systems, the hydraulic motors enable the kinetic energy of the oil fluid to be converted into the mechanical energy of a primary section of a linear motor through a gear transmission mechanism, and the primary section of the linear motor moves back and forth in a secondary section to cut magnetic induction lines so as to generate electric currents which are stored in vehicle-mounted cells through the energy reclaiming circuit. In addition, data collected by an ECU of the energy reclaiming control module through displacement sensors can realize active control on the acting force of the suspensions. Two working modes are switched, so that not only is the riding comfort of a vehicle improved, but also partial vibration energy is recovered, and the functions of saving energy and reducing emission are realized.

Description

technical field [0001] The invention relates to an active hydraulic interconnected energy-feeding suspension, which belongs to the technical field of vehicle suspension. Background technique [0002] A hydraulic interconnected suspension is generally installed on a heavy-duty vehicle with a high center of gravity. Compared with the traditional independent suspension, it can not only reduce the natural frequency of the vehicle, but also effectively improve the handling stability of the vehicle. For example, a vehicle with a hydraulic reverse interconnected suspension has a smaller roll angle than other vehicles when turning, thereby improving driving safety. [0003] Although the interconnected suspension can improve the performance of the vehicle, there is friction between the oil and the pipe wall during the transmission of the oil in the system pipeline, and there is internal friction between the oil molecules. Changes in the direction and cross-sectional area of ​​the pip...

Problems solved by technology

However, due to the introduction of the hydraulic rectifier bridge, the active control effect of the suspension system is greatly weakened, because the check valve's check effect makes it difficult for the downstream oil to affect the upstream flow state, and the introduction of a large number of check valves It also makes the pressure loss of the system further increase, and the cost of equipment installation and maintenance also increases accordingly
