Magnetic suspension active suspension device capable of recycling vibrating energy

Abstract

The invention discloses a magnetic suspension active suspension device capable of recycling vibrating energy. The magnetic suspension active suspension device comprises a shock absorber between a vehicle body and a chassis, wherein the shock absorber comprises a cylinder block; an upper support rod and a lower support rod are arranged at the upper part and the lower part of the cylinder block separately in a penetrating manner; a permanent magnet is arranged between the upper support rod and the lower support rod and comprises an inner magnet coil and a main permanent magnet movably arranged;the end of the inner magnet coil penetrates through the shock absorber to be electrically connected with a current controller; a coil external winding is arranged on the outer side of the cylinder block in a sleeving manner and is sequentially electrically connected with a rectifier and an energy recoverer; a suspension spring is arranged on one side of the shock absorber in parallel; and the twoends of the suspension spring are connected with the vehicle body and the chassis separately. The magnetic suspension active suspension device can solve the problem in the prior art that an active suspension is insufficient in energy utilization efficiency and cannot adjust the rigidity, and is simple and reliable in structure, and high in adjustability and detecting speed.

Description

technical field [0001] The invention relates to an automobile suspension, in particular to a magnetic suspension active suspension device with vibration energy recovery. Background technique [0002] With the continuous development of automobiles, people have higher and higher requirements for automobiles. To measure the quality of a car, not only its power performance, but also its ride comfort are essential. Vehicle suspension is one of the important assemblies on the car, elastically connecting the body and chassis together, and plays a vital role in the ride comfort of the car. The main function of the suspension is to transmit all the forces and moments acting between the chassis and the body, and ease the impact load transmitted to the body due to uneven roads, attenuate the vibration caused by it, ensure the comfort of the occupants, and reduce the load and vehicle load. Its own dynamic load, and ensure that the car has a good ride comfort. [0003] Modern suspensio...
