The invention relates to a shock absorber device with the energy recovery function for vehicles. The shock absorber device comprises a hydraulic cylinder, a piston rod, a piston and a double input shaft motor; a small opening is formed in a lower cavity of the hydraulic cylinder and is connected to a first primary high-pressure oil pipe branch, a small opening is formed in an upper cavity of the hydraulic cylinder and is connected to a second primary high-pressure oil pipe branch, a first high-pressure oil pipe branch and a second high-pressure oil pipe branch are communicated between the first primary high-pressure oil pipe branch and the second primary high-pressure oil pipe branch, a second check valve, a first hydraulic motor and a first check valve are sequentially connected to the first high-pressure oil pipe branch, a third check valve, a second hydraulic motor and a fourth check valve are sequentially connected to the second high-pressure oil pipe branch, the first hydraulic motor is connected to one input shaft of the double input shaft motor through a first connecting shaft, and the second hydraulic motor is connected to the other input shaft of the double input shaft motor through a second connecting shaft. According to the invention, on the premise of not changing the vibration damping performance of traditional passive suspensions, the energy is fully recovered and is saved.
Description
technical field [0001] The invention relates to an automobile vibration energy recovery device, which belongs to the technical field of automobile energy saving. Background technique [0002] With the development of the economy, the number of private cars continues to increase, and at the same time, the problem is that the consumption of fossil fuels is also increasing. As we all know, gasoline, diesel, natural gas, etc. that traditional cars rely on are all non-renewable energy sources, and the existing reserves of these energy sources are only enough for human beings to use for several decades. Therefore, energy saving and emission reduction has been put on the agenda of governments all over the world. [0003] When a car is running, only about 30% of the energy produced by consuming fossil fuels is converted into the kinetic energy of the car, and about 70% of the energy is dissipated in the form of heat in friction, vibration and other processes. If the 70% of the ener...
