Problems solved by technology

The additional mass of the hydraulic energy storage type energy-feeding shock absorber is heavy, the response speed is slow, and the execution accuracy is low
The energy recovery efficiency of the electromagnetic energy-feeding shock absorber is higher than that of the hydraulic energy storage type, but there is a problem that the motor rotor rotates forward and reverse alternately with the reciprocating movement of the suspension.
Moreover, these shock absorbers cannot realize the adjustment of the damping force well.

Abstract

The invention discloses an energy-reclaiming type shock absorber. The energy-reclaiming type shock absorber comprises a cylinder barrel and a rotor assembly, wherein the rotor assembly comprises a rotary shaft rotatably arranged on the cylinder barrel and a piston and a first permanent magnet arranged on the rotary shaft; the rotor assembly also comprises a magnetic shielding device arranged on the rotary shaft for adjusting the quantity of magnetic induction lines passing through a magnetorheological fluid; and the magnetic shielding device is located between the cylinder barrel and the firstpermanent magnet. According to the energy-reclaiming type shock absorber disclosed by the invention, the quantity of the magnetic induction lines passing through the magnetorheological fluid is adjusted by arranging the magnetic shielding device, so that the intensity of the magnetorheological effect can be further adjusted, and the damping force of the shock absorber can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular, the invention relates to an energy-feeding type shock absorber. Background technique [0002] At present, there are generally two types of research on energy-feeding shock absorbers at home and abroad: hydraulic energy storage type and electromagnetic type. Among them, there are five types of electromagnetic energy-feeding suspensions: electromagnetic coil induction type, linear motor type, crank connecting rod type, rack and pinion type and ball screw type. The hydraulic energy storage type energy-feeding shock absorber has heavy additional mass, slow response speed and low execution accuracy. The energy recovery efficiency of the electromagnetic energy-feeding shock absorber is higher than that of the hydraulic energy storage type, but there is a problem that the motor rotor rotates forward and reverse alternately with the reciprocating motion of the suspension.
