Problems solved by technology

[0002] Magneto-rheological damper is an intelligent damping device. The existing magneto-rheological damper mostly adopts the structure of piston and working cylinder. This type of magnetorheological damper changes the current entering the excitation coil in the piston to make the The change of the electromagnetic field intensity in the annular gap between the outer diameter and the inner diameter of the working cylinder (ie: the working gap) is used to adjust the viscosity of the magnetorheological fluid to adjust the damping force. Due to the work of this magnetorheological damper There is only one gap, so the range of damping force adjustment is small

Abstract

The invention discloses a magnetorheological damper with a float ring and double outlet rods. The magnetorheological damper comprises a working cylinder, the float ring, a piston, two piston rods and an external electromagnet. End covers are fixed to two ends of the cylindrical working cylinder; a plurality of identical annular discs are fixed onto the same core column to form the piston, and excitation coils are wound in annular gaps among the various annular discs of the piston; the piston is mounted in the working cylinder, and magnetorheological fluid flowing gaps are reserved between the outer peripheral wall of the piston and the inner peripheral wall of the float ring and between the outer peripheral wall of the float ring and the inner peripheral wall of the working cylinder; one ends of the two piston rods are respectively fixed to two ends of the piston, and the other ends of the two piston rods extend out of the two ends of the working cylinder via sealing devices and sliding bearings on the two end covers of the working cylinder; the gaps in the working cylinder, between the inner peripheral wall of the float ring and the outer peripheral wall of the piston and between the outer peripheral wall of the float ring and the inner peripheral wall of the working cylinder are filled with magnetorheological fluid; the external electromagnet is fixed onto the outer circumference of the working cylinder.

Description

technical field [0001] The invention relates to a magnetorheological damper, in particular to a magnetorheological damper with floating rings and double rods. Background technique [0002] Magneto-rheological damper is an intelligent damping device. The existing magneto-rheological damper mostly adopts the structure of piston and working cylinder. This type of magnetorheological damper changes the current entering the excitation coil in the piston to make the The change of the electromagnetic field intensity in the annular gap between the outer diameter and the inner diameter of the working cylinder (ie: the working gap) is used to adjust the viscosity of the magnetorheological fluid to adjust the damping force. Due to the work of this magnetorheological damper There is only one gap, so the range of adjustment of the damping force is small. Contents of the invention [0003] In order to overcome the shortcomings of the existing magnetorheological damper with only one work...
