Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] figure 1 The structure of the magneto-rheological shock absorber 100 according to the present invention is schematically shown. like figure 1 As shown, the magneto-rheological shock absorber 100 according to the present invention includes a cylinder 10 and a piston unit 20 . Therein, the cylinder body 10 is configured as a hollow sleeve, and a chamber 11 is formed in the cylinder body 10 . Chamber 11 is used to accommodate magnetorheological fluid (not shown). The piston unit 20 is disposed within the chamber 11 of the cylinder 10 and is capable of reciprocating movement within the chamber 11 of the cylinder 10 . Magneto-rheological fluid (MRF) is a new type of intelligent liquid material, which is mainly composed of non-magnetic liquid and high magnetic permeability and low hysteresis micro-magnetic particles uniformly dispersed in it. Under the action of a mag...

Abstract

The invention belongs to the field of shock absorbers, and particularly discloses a magnetorheological shock absorber. The magnetorheological fluid is contained in the cylinder body, and the piston unit is arranged in the cylinder body. The piston unit comprises a piston rod and a circulation piece arranged on the piston rod in a sleeving mode. The first connecting part of the piston rod horizontally extends outwards from the first side end face of the cylinder body. The shock absorber further comprises a connector fixedly connected with the first connecting part of the piston rod. The circulation piece comprises a magnetic field generator, and the magnetic field generator can generate a magnetic field acting on the magnetorheological fluid. The damping force can be intelligently adjusted.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a magnetorheological shock absorber. Background technique [0002] Magneto-rheological shock absorbers are usually used in mechanical equipment with high-intensity impact environments. Examples include vehicle technology, reciprocating machinery, bridges and high-rise buildings. The magnetorheological shock absorber can buffer the impact load. However, the magneto-rheological shock absorber in the prior art cannot be applied to different impact loads, and cannot alleviate the impact load due to its limited capacity. Contents of the invention [0003] The purpose of the present invention is to propose a magneto-rheological shock absorber, which enables the piston unit to form different magneto-rheological fluid flow channels in the process of compression and reset by setting a one-way control valve, thereby realizing intelligent adjustment of the damping force . [0004] Accor...
