Abstract

The invention discloses a hydraulic damping energy recovery device of an automobile. The hydraulic damping energy recovery device comprises a hydraulic cylinder (5), the hydraulic damping energy recovery device further comprises a hydraulic electric generator (6), and an oil port of the hydraulic cylinder (5) and an oil port of the hydraulic electric generator (6) are connected through oil pipes (9). The oil pipe (9) between a rod cavity oil port and an oil inlet is provided with a first check valve (1), the oil pipe (9) between an oil outlet and a rodless cavity oil port is provided with a second check valve (2), the oil pipe (9) between the rodless cavity oil port and the oil inlet is provided with a third check valve (3), and the oil pipe (9) between the oil outlet and the rod cavity oil port is provided with a fourth check valve (4). The mode that the hydraulic electric generator converts vibration energy into electric energy is used, the vibration energy is reasonably recycled, and energy waste is avoided. The invention further discloses the automobile including the hydraulic damping energy recovery device.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a hydraulic vibration damping energy recovery device for automobiles. Furthermore, the invention also relates to a motor vehicle with the device described above. Background technique [0002] When the car is running, it is inevitable that it will encounter a bumpy road section, and the car will generate a large vibration at this time. In order to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the car, it is necessary to install a shock absorber in the car. [0003] There are many types of shock absorbers for automobiles, among which hydraulic shock absorbers are widely used. The following is a brief introduction to the working principle of the hydraulic shock absorber. During the compression stroke, it means that the wheel of the car moves closer to the body, the shock absorber is compressed, and the piston in the shock absorber ...
