Abstract

The invention discloses a vibration energy recycling type magnetorheological damper, and belongs to the technical field of automobile energy saving. According to the vibration energy recycling type magnetorheological damper, vibration energy of a suspension can be converted into electric energy, the vibration energy is recycled, and the vehicle energy use ratio is increased. The vibration energy recycling type magnetorheological damper comprises a magnetorheological damper module, a piezoelectric stack module, and an electromagnetic induction power generation module. The magnetorheological damper module comprises an upper installation lifting ring, a piston rod, a piston ring, magnetorheological fluid, a primary damping spring, an excitation coil and a base; a cylinder cavity is filled with the magnetorheological fluid, the excitation coil is installed in a piston ring groove, and connected with an external power source; the piezoelectric stack power generation module is composed of apiezoelectric stack and a force transmission spring; and the electromagnetic induction power generation module comprises a permanent magnet and an induction coil. The piston rod is connected with thepermanent magnet and moves to cut the magnetic field line to convert the vibration energy into the electric energy, and the induction coil is connected with a rectifying circuit for recycling. According to the vibration energy recycling type magnetorheological damper, the vibration energy is converted into the electric energy while active vibration isolation is realized, the vibration energy is recycled, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile energy saving, in particular to an automobile energy recovery device, that is, to a vibration energy recovery type magneto-rheological shock absorber. Background technique [0002] With the reduction of energy and the improvement of people's energy-saving awareness, how to improve the energy-saving and environmental protection of automobiles has become the research goal of automobile design engineers. When a vehicle passes through an uneven road, the body of the car will vibrate, and the more uneven the road, the stronger the vibration of the car. Normally, the vibration energy will be lost by the heat generated by the oil friction inside the shock absorber. If the vibration energy of the shock absorber can be recovered and reused, the purpose of energy saving can be achieved. At present, the vibration energy of domestic commercial vehicle suspension shock absorbers has basically not been effe...
