Hydraulic electricity generation shock absorber of vehicle

Abstract

The invention discloses a hydraulic electricity generation shock absorber of a vehicle, belonging to the technical field of vehicle suspension systems and hydraulic transmission. The hydraulic power generation shock absorber of the vehicle generates electricity by utilizing pressure generated by hydraulic oil during shock absorption and comprises a piston shock absorption part, a valve path part and an electricity generation part, wherein the piston shock absorption part comprises a hydraulic cylinder (1) and a piston (2); the electricity generation part comprises a hydraulic motor (13) and an electric generator (16); and the piston (2) is pushed to move up and down in the hydraulic cylinder (1) during the shock absorption of the vehicle so that the hydraulic oil inside the hydraulic cylinder (1) is extruded out of the outlet of an upper cavity or a lower cavity of the hydraulic cylinder (1) and passes through the valve path part and then pushes the hydraulic motor (13) to drive the electric generator (16) to generate the electricity. The invention makes the hydraulic shock absorber of the vehicle possible have both stable shock absorption and electricity generation performance by adopting a reliable and mature hydraulic transmission technology and also provides a new research direction for the developed hydraulic shock absorber.

Description

technical field [0001] The invention relates to the configuration of a vehicle suspension system, in particular to a vehicle hydraulic power generation shock absorber which can recover mechanical vibration energy for power generation. Background technique [0002] With the increasing shortage of fossil fuels and the gradual improvement of people's requirements for vehicle energy-saving performance, various ways of recovering braking energy and other forms of energy in the vehicle industry have become one of the hotspots in the field of vehicle energy-saving research. [0003] As a key component of the vehicle suspension system, the shock absorber plays a role in shock absorption, maintenance and improvement of vehicle comfort and stability. The vehicle hydraulic shock absorber commonly used at present is arranged between the vehicle frame and the vehicle axle. When the piston in the shock absorber moves up and down, the oil in the shock absorber cavity is circulated from on...

Problems solved by technology

This solution has the problems of high production cost and low reliability

When it is applied to heavy vehicles or off-road vehicles, super strong permanent magnets must be used, which are expensive, heavy and can affect vehicle electronics

At the same time, the plan does not mention the quality of the generated electric energy, such as voltage and current, etc., and the electric energy is difficult to be used by vehicles, and it is difficult to promote industrially.
