The suspension system with the energy recovery device comprises a suspension cushion and a suspension bracket; the suspension bracket is provided with an energy recovery device, and the energy recovery device is composed of a ball pin mechanism, a hydraulic device, a turbine mechanism and a one-way valve; the hydraulic device comprises a barrel body which is internally provided with a piston, and a rod body of the piston is arranged in the Z direction; the outer wall of the barrel body is provided with a first pipeline and a second pipeline which communicate with the interior of the barrel body; the turbine mechanism is arranged between the middles of the first pipeline and the second pipeline, and the lower end of the second pipeline is provided with the one-way valve; and one end of the ball pin mechanism is connected with the suspension bracket, and the other end of the ball pin mechanism is connected with a rod body of a piston rod. According to the suspension system provided by the invention, irrgular movement is converted into Z-direction movement, the energy recovery and utilization efficiency is improved, in addition, X-direction vibration and Y-direction vibration of the energy recovery device are reduced, and the reliabilityof the suspension system is improved.

Description

technical field [0001] The present invention relates to automobile design and manufacture, and more particularly, the present invention relates to a suspension system with an energy recovery device. Background technique [0002] figure 1 The structure of the suspension system without energy recovery device in the prior art is shown, which is mainly composed of a suspension cushion assembly 1 and a suspension bracket 2 . The main function of the suspension system is to attenuate the vibration between the powertrain and the body or frame. The energy of the vibration is not recovered, resulting in a waste of energy. In order to recover the vibration energy during driving, Wuhan University of Technology discloses a vane type energy recovery shock absorber in CN102926956A, in order not to produce reverse phenomenon, which adopts four one-way valves, and adopts a mechanical accumulator , air bag type accumulator etc., the structure is complicated, and it takes up a lot of space,...

The main function of the suspension system is to attenuate the vibration between the powertrain and the body or frame, and the energy of the vibration is not recovered, resulting in a waste of energy

In order to recover the vibration energy during driving, Wuhan University of Technology discloses a vane type energy recovery shock absorber in CN102926956A, in order not to produce reverse phenomenon, which adopts four one-way valves, and adopts a mechanical accumulator , airbag accumulator, etc., have complex structures, occupy a large space, and are difficult to popularize and utilize

CN1030099956A discloses an energy storage suspension device with vibration energy recovery, in which energy recovery is realized by means of spring transmission, and three check valves are used, which not only reduces the recovery efficiency of vibration energy, but also has a relatively Complicated, where the hydraulic cylinder is directly located between the body and the wheel (i.e., the sprung mass and the unsprung mass), which has been verified to cause large vibrations in the X and Y directions of the hydraulic cylinder, and the reliability of the system is also poor
