Abstract

The invention discloses a magnetoelectric self-powered suspension shock absorber of an electric vehicle. The magnetoelectric self-powered suspension shock absorber is characterized in that the magnetoelectric self-powered suspension shock absorber is combined with a power generation structure based on a magnetorheological shock absorber structure, a self powering function is achieved through the electromagnetic principle, a piston rod and a shock absorber barrel relatively move through ground vibration during vehicle driving, a magnet exciting coil at the outer part of the shock absorber cuts a magnetic field generated by a permanent magnet on the piston rod, so that induced electromotive force is generated; and a coil inside a piston is powered through an external control system, and a magnetic field is generated, so that the property of a magnetorheological fluid is changed, and the effect of changing the damping of the shock absorber is achieved. The magnetoelectric self-powered suspension shock absorber has the advantages that the size is small, the mass is light, external power supply is not required, the structural reliability is high, and the like.

Description

technical field [0001] The invention belongs to the technical field of vibration energy recovery of a semi-active suspension, and in particular relates to a magnetic-electric self-powered suspension shock absorber for an electric vehicle. Background technique [0002] Intelligence and integration are the development trend of the vehicle chassis control system. With its excellent performance, the magnetorheological semi-active suspension system greatly improves the ride comfort and handling stability of the vehicle. In recent years, with the continuous increase of people's demand for energy and the aggravation of global energy shortages, self-powered technology has become a hot spot of research and attention by scholars from all over the world. Although magnetorheological semi-active suspension can effectively adjust the suspension system to reduce the The damping of the shock absorber, but it needs an external power supply, and the increase of the external power supply syste...
