Problems solved by technology

[0004] (1) The coil is surrounded by magneto-rheological fluid. Since the coil is energized and the heat generated by the damper is concentrated near the coil, it is easy to burn out the coil.
[0005] (2) When the coil is replaced after the coil is burned out, it is necessary to disassemble the seal of the cylinder to replace the coil, which brings inconvenience to the maintenance work
[0006] (3) Since the coil needs to be connected to an external power supply, the guide wire needs to be drilled through

Abstract

The invention discloses a magnetorheological damper with convenience in assembly and disassembly of a coil component, relating to the technical field of magnetorheological dampers. The magnetorheological damper comprises a damping cylinder barrel, the coil component, a piston, a piston rod and a magnetorheological fluid, and is characterized in that the coil component is fixed on the outer side of the damping cylinder barrel, a magnetorheological fluid flow channel is arranged on the damping cylinder barrel, the coil component is not in contact with the magnetorheological fluid, the coil component is simple to assemble and disassemble, and the heat generated by energy consumption of an electromagnetic coil and the magnetorheological damper can be uniformly dissipated through the whole outer-layer cylinder barrel component and the coil component, thus the heat dissipation area is large, the temperature of the electromagnetic coil can be obviously reduced, and the service life of the electromagnetic coil can be prolonged.

Description

technical field [0001] The invention relates to the technical field of magnetorheological fluid dampers, in particular to a magnetorheological damper with convenient assembly and disassembly of coil components. Background technique [0002] The magnetorheological damper is a new type of semi-active damping device. It is developed according to the principle that the rheological characteristics of magnetorheological fluid can be controlled under the action of a magnetic field. It has the advantages of wide adjustment range of damping force, fast response speed, simple structure and easy control. , is an efficient vibration isolation and anti-seismic device, and has been successfully applied in the fields of vehicle system vibration isolation and building structure anti-seismic. [0003] The common magnetorheological damper winds the electromagnetic coil on the piston of the damper, and an annular channel is set on the piston or between the piston and the cylinder. During opera...
