Embodiment

[0045] see Figure 1 to Figure 6 , a bottom channel magneto-rheological damper with a settling active dispersion device, characterized in that it includes a liquid cylinder 1, a bottom cover 2, a positioning column 3, a rotor 4, a stator 5, a top cover 6, a working cylinder 7, and a piston Assembly 8 and piston rod 9.

[0046] The liquid cylinder 1 is a hollow cylinder, and the opening at its lower end has threads.

[0047] The upper end of the bottom cover 2 is a ring I201. The outer wall of the ring I201 has threads. The lower end of the bottom cover 2 is a disc I202. The disc I202 has a circular hole I2021 in the center of the end face. The end surface of the disc I202 is provided with several counterbore holes 2022 on the same circumference.

[0048] The upper end of the bottom cover 2 is screwed onto the opening of the lower end of the liquid cylinder 1 . The liquid cylinder 1 and the bottom cover 2 are sealed by an O-ring.

[0049] The positioning column 3 is inst...

Abstract

The invention discloses a bottom channel magneto-rheological damper with a settling and active-dispersing device. The bottom channel magneto-rheological damper comprises a liquid barrel, a bottom cover, a positioning column, a rotor, a stator, a top cover, a working cylinder, a piston assembly and a piston rod, wherein the upper end of the bottom cover is mounted in an opening in the lower end ofthe liquid barrel; a spiral rib is arranged on the outer peripheral wall of the rotor; the rotor is positioned in the liquid barrel; the stator comprises an outer barrel and an inner barrel; a plurality of magnetic poles are arranged between the inner barrel and the outer barrel; the stator is arranged on the rotor in a sleeving manner, and is positioned in the liquid barrel; an inner channel is formed between the stator and the rotor; an outer channel is formed between the stator and the liquid barrel; the top cover is mounted at the upper end of the stator; the working cylinder is positionedin the liquid barrel, and is filled with magneto-rheological liquid; the piston assembly is positioned in the working cylinder; and the piston rod is mounted on the piston assembly. The bottom channel magneto-rheological damper realizes re-dispersion after magneto-rheological liquid is settled, and is beneficial for energy recycling when the magneto-rheological damper normally works.

Description

technical field [0001] The invention relates to the field of magnetorheological dampers, in particular to a bottom channel magnetorheological damper with a settlement active dispersion device. Background technique [0002] Magnetorheological fluid is a suspension formed by mixing tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic liquid. This kind of suspension exhibits low-viscosity Newtonian fluid characteristics under the condition of zero magnetic field; while under the action of strong magnetic field, it presents high-viscosity, low-fluidity Bingham fluid characteristics. In the case of zero magnetic field, the magnetorheological fluid behaves as a liquid with good flow performance, and its apparent viscosity is very small; under the action of a strong magnetic field, the apparent viscosity can increase by more than two orders of magnitude in a short time (milliseconds), and presents Solid-like properties; and this...
