Abstract

The invention aims to provide a hybrid electromagnetic energy feedback damper. The hybrid electromagnetic energy feedback damper comprises a piston rod, an upper end cover, a cylinder body and a piston head, magnetorheological fluid is injected into the cylinder body, so that a stepped magnetorheological fluid damping gap is formed between the piston head and the inner side of the cylinder body, and the length of a damping channel is effectively increased. The electromagnetic energy feedback damper is organically combined with the magnetorheological fluid damper, on one hand, the maximum damping force value is increased, meanwhile, the conductor shell structure of the stepped ring surface of the piston head is convenient to replace, and the magnetorheological fluid damper can adapt to various different working environments; and on the other hand, the utilization rate of magnetic lines generated by the permanent magnet and the coil is higher, the damping force adjusting range is larger, the size is small, and practicability is high. The hybrid electromagnetic energy feedback damper overcomes the defects that in the prior art, damping force cannot be adjusted, and output damping force is small, and has the advantages of being adjustable in damping channel gap size and capable of outputting the maximum damping force.

Description

technical field [0001] The invention relates to an automobile suspension damper device, in particular to a hybrid electromagnetic energy feed damper. Background technique [0002] The electromagnetic energy-feeding suspension technology mainly uses the generator principle. The main components are permanent magnets, transmission mechanisms and coil windings. Aiming at the vibration energy obtained by the suspension due to uneven road surfaces, the coils are used to cut the magnetic lines of force to generate electromagnetic induction principles. The vibration energy is converted into electrical energy that can be stored and used, and the energy conversion is simple and the response is fast. [0003] With the development of the industrial level, how to effectively save energy and reduce emissions has become a current research hotspot. In order to improve the maximum damping force and adjustment range of the energy-feeding electromagnetic damper, most of the existing electroma...
