HYDRAULIC SHOCK ABSORBER WITH ELECTRIC GENERATOR Russian patent published in 2022 - IPC F16F9/16 B60G13/14 

FIELD: transport engineering.

SUBSTANCE: invention relates to the field of transport engineering. The hydraulic shock absorber consists of a cylinder and a compensation chamber connected by a high-pressure pipeline. A piston made of two plates is installed inside the cylinder. The upper plate is rotatable relative to the lower one. Rotation is carried out by means of a spring, which changes its length when the temperature changes. Recoil and compression valves are installed in the piston. The compensation chamber in the upper part is filled with an inert gas. An additional piston is installed in the compensation chamber, made of a set of annular magnets facing each other with opposite poles, and connected to two elastic diaphragms. The compensation chamber is made of non-magnetic material, and the windings of an electric generator are installed on its outer walls.

EFFECT: it is possible to recover the vibration energy of the vehicle into electrical energy.
