A hydraulic energy storage damping adjustment semi-active suspension system

Abstract

The invention relates to the technical field of vehicle energy saving and emission reduction, in particular to a hydraulic energy storage damping adjustment semi-active suspension system, which includes a spring arranged between the vehicle body and the wheels, a damping device is arranged between the vehicle body and the wheels, and the damping device It includes the piston rod fixed on the wheel and the piston cylinder fixed on the vehicle body. The piston rod is fixed with a piston that matches the piston rod; the rod chamber and the rodless chamber of the piston cylinder are connected in parallel with vibration-absorbing oil circuit and damping oil. There is a first one-way valve on the vibration-absorbing oil circuit to allow the oil to flow from the rodless chamber to the rod chamber, and a hydraulic motor and a second one-way valve to allow the oil to flow from the rod chamber to the rodless chamber on the damping oil circuit. , The hydraulic motor is connected with a generator, the generator is connected with a load regulating circuit, the load regulating circuit is provided with a load resistance and a resistance regulating device, and the electricity generated by the generator is stored through the battery. The invention realizes the adjustment of the damping force of the suspension, has a simple structure, is convenient to control, is beneficial to realization, and can effectively improve the running comfort of the automobile.

Description

technical field [0001] The invention relates to the technical field of vehicle energy saving and emission reduction, in particular to a hydraulic energy storage damping adjustment semi-active suspension system. Background technique [0002] With the continuous increase of the number of automobiles and the improvement of national requirements for energy conservation and environmental protection, automobile energy conservation and emission reduction has become the primary issue facing the development of the automobile industry. Electric vehicles have become a national key development target due to their advantages of zero emissions, but the long charging time and relatively short mileage of vehicles limit their development and application. If the vibration energy of the car body can be recycled during the driving process of the car, it will effectively increase its mileage and improve the economy of the car. [0003] At present, traditional shock absorbers such as hydraulic s...

Problems solved by technology

[0003] At present, traditional shock absorbers such as hydraulic shock absorbers or magneto-rheological shock absorbers used in automobile suspension systems are difficult to achieve continuous adjustment of the damping force under different operating conditions of the car, and at the same time convert the vibration energy of the up and down movement of the car body into heat energy Consumption is not conducive to the improvement of the economic performance of the car
