Abstract

The invention discloses a vibration energy recovering device. The vibration energy recovering device comprises a vibration receiving device and an energy feedback device, wherein the vibration receiving device can be a damper or a hydraulic cylinder; the energy feedback device comprises a hydraulic loop, a one-way valve system and a hydraulic motor; two main branches of the hydraulic loop are connected with different cavities of the vibration receiving device respectively; two parallel hydraulic branches are connected in series with one-way valves and hydraulic motors respectively; the one-way valves are arranged oppositely in order that the two branches only generate opposite fluid flow in a single direction. According to the working principle, a piston assembly rod of the vibration receiving device (1) is used for receiving external vibration; the piston assembly rod and a cylinder block perform generate relative movement; pressure is generated in the cylinder, and hydraulic oil flows into the energy feedback device (2); when a second cavity (14) is compressed, a first one-way valve (220) is switched on, and a first hydraulic motor (222) works; when a second cavity (10) is compressed, a second one-way valve (240) is switched on, and a second hydraulic motor (242) works. The vibration energy recovering device is simple in structure, and has high reliability; energy of movement in two directions during vibration can be efficiently recovered, and a damping effect is achieved.

Description

technical field [0001] The invention relates to vibration energy recovery technology, in particular to a vehicle suspension system, which is used to collect the energy generated by the vibration of the vehicle body when the vehicle is running. Background technique [0002] Vibration reduction systems have been widely used in industrial design, such as vehicle suspension systems. Most of the traditional vibration reduction measures convert kinetic energy into heat energy and consume it without recycling. [0003] Taking the traditional vehicle suspension system as an example, most of the vibration generated by the vehicle during driving on the road is used by the shock absorber to convert the vibration energy into heat energy and dissipate it, thereby attenuating the vibration. A lot of dissipated energy has not been effectively recycled. Effective recycling of it is an important means to achieve energy conservation and environmental protection. [0004] The linear energy-fe...
