Problems solved by technology
In related technologies, electrorheological and magnetorheological shock absorbers are used to realize the automatic adjustment of the damping effect, but the yield strength of the electrorheological fluid is small, the working temperature range is narrow, the zero electric field viscosity is high, and the solid particles in the suspension and the foundation The specific gravity difference between the liquids is large, easy to separate, and the settlement stability is poor, which will lead to unstable changes in the damping force when the shock absorber is working, and it is difficult to meet the needs of long-term stable work, and there is room for improvement

The invention discloses a shock absorber and a vehicle, which comprises a cylinder body used for defining a piston chamber for containing an ionic solution, a piston movably arranged in the piston cavity comprising a microporous membrane and an electrode which are arranged in a stacked mode. The electrode is arranged at a position provided with a flow passage through which the ionic solution passes. The shock absorber is configured to adsorb ions when the electrode is energized to adjust the flow area of the microporous membrane. According to the shock absorber disclosed by the invention, theflow area of the microporous membrane can be changed through the adsorption effect of the electrode on ions in the ion solution, so that the damping force of the shock absorber can be adjusted to adapt to the current running state, accordingly the adjusting mode is simple, and the adjusting effect is good.
Description
technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a shock absorber and a vehicle with the shock absorber. Background technique [0002] The shock absorber is the damping element in the suspension system. When the car body and wheels vibrate, the friction of the liquid in the shock absorber when it flows through the damping hole and the viscosity of the liquid will form vibration resistance, transform the vibration energy into heat energy, and achieve attenuation purpose of vibration. In related technologies, electrorheological and magnetorheological shock absorbers are used to realize automatic adjustment of the damping effect, but the yield strength of the electrorheological fluid is small, the working temperature range is narrow, the zero electric field viscosity is high, and the solid particles in the suspension and the foundation The specific gravity difference between the liquids is large, easy to separate, a...
