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

Embodiment Construction

[0025] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.

[0026] Reference below figure 1 The shock absorber 100 according to the embodiment of the present invention is described. The shock absorber 100 can automatically adjust the circulation efficiency of the shock absorber fluid according to the operating state of the vehicle, and then automatically adjust the damping force of the shock absorber 100, so that the vehicle is in different conditions. The shock absorber 100 has an appropriate damping force in the driving state of the whole vehi...

Abstract

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 present invention relates to the technical field of vehicle manufacturing, and in particular, to a shock absorber and a vehicle having the shock absorber. Background technique [0002] The shock absorber is the damping element in the suspension system. When the vehicle body and the 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, and the vibration energy will be converted into heat energy to achieve attenuation. purpose of vibration. In the related art, the automatic adjustment of the vibration damping effect is realized by the electrorheological and magnetorheological dampers, but the yield strength of the electrorheological liquid is small, the working temperature range is narrow, the zero electric field viscosity is high, and the solid particles in the suspension are closely related to the foundation. The difference in specific...
