Example Embodiment

[0018] The present invention will be further described below in conjunction with the drawings and embodiments.

[0019] Such as figure 1 Among them, the vehicle hydraulic power generating shock absorber of the present invention includes a piston shock absorbing part, a valve circuit part and a power generating part.

[0020] The piston damping part is composed of hydraulic cylinder 1 and piston 2. The upper and lower chambers of the hydraulic cylinder each have an opening and a copper pipe is connected. When the vehicle encounters road bumps and generates vibration or starts and brakes, it will cause relative movement between the vehicle frame and the wheels. At this time, the shock absorber piston 2 will move up or down accordingly under the force of The oil is pressed out from the corresponding upper cavity outlet and sucked in from the lower cavity outlet, or hydraulic oil is pressed out from the corresponding lower cavity outlet and sucked in from the upper cavity outlet.

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...
