Abstract

The invention discloses a multilayer pressure-reduction magnetorheological damper. The multilayer pressure-reduction magnetorheological damper is characterized in that the multilayer pressure-reduction magnetorheological damper comprises a sleeve, a permanent magnet, fixing mechanisms, a regulating mechanism, a sliding sleeve, a limiting mechanism and a sealing mechanism, wherein the permanent magnet is arranged on the inner wall of the sleeve, an end cover is arranged on the lower part of the sleeve, the fixing mechanisms are arranged at the upper end and the lower end of the magnetorheological damper correspondingly, the regulating mechanism is arranged inside the sleeve, the sliding sleeve is arranged on the outer side of the sleeve, the limiting mechanism is arranged at the bottom of the sliding sleeve and connected with the sliding sleeve, and the sealing structure is arranged on the outer wall side of the upper part of the regulating mechanism. The magnetorheological damper is provided with the two fixing mechanisms so that the reverse rheological damper can be stably mounted at the designated position, a plurality of fixing frames with coils are arranged in the regulating mechanism, thus magnetic force with specified intensity can be provided after electrification, the sliding sleeve and the limiting mechanism are arranged outside the sleeve, and thus the stability of the magnetorheological damper is improved.

Description

technical field [0001] The invention relates to the technical field of dampers, in particular to a magneto-rheological damper with multi-layer decompression. Background technique [0002] The damper is a device that uses damping characteristics to slow down mechanical vibration and consume kinetic energy. It is commonly used in the suspension system of automobiles and motorcycles. It is also found on some bicycles. It uses damping to absorb energy and absorb shocks. Various dampers (or shock absorbers) have been used in guns, automobiles, construction and other industries to reduce vibration and energy dissipation. [0003] However, the traditional multi-layer decompressed magneto-rheological damper cannot realize the damper coil electromagnetism when the power is not turned on, which makes the stability of the damper poor. [0004] Therefore, it is necessary to provide a new multi-layer decompression magneto-rheological damper to solve the above technical problems. [000...
