Embodiment Construction

[0024] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0025] Such as Figure 1 to Figure 4 Shown is the magneto-rheological fluid damper of the present invention, which includes a working cylinder 6, a piston 9 and a slidable piston rod 3 located in the working cylinder 6, and the piston rod 3 passes through the upper cover 5 and your sealing cover 7. The lower end of the piston rod 3 is inserted into the working cylinder 6 and connected with the piston 9; the outer circular surface of the piston 9 is in close contact with the inner wall of the working cylinder 6; the piston 9 divides the working cylinder 6 into two working chambers, that is, the upper Working chamber 15 and lower wor...

Abstract

The invention discloses a magnetorheological fluid damper. A piston is provided with a damping channel connecting two working cavities. The structure of the damping channel is as follows: a sliding groove and a slider in sliding fit with the sliding groove are arranged on the piston, the slider can move in the radial direction of the piston in the sliding groove, the slider faces the end surface of the inner wall of a working cylinder, a clearance is arranged between the slider and the inner wall of the working cylinder, and the two working cavities communicate with each other through the clearance. Due to the adoption of the technical scheme, the damping channel is controlled through the slider on the piston of the damper; not only can damping output be changed through the magnetic field variation of magnetorheological fluid, damping output can also be changed through the variation of the damping channel; and damping requirements under violet impact can be well solved. Compared with the prior art, the magnetorheological fluid damper has the advantages of being wide in damping output range, rapid in output response, simple in structure, reliable in performance, low in production cost and the like.

Description

technical field [0001] The invention belongs to the technical field of vehicle damping devices. More specifically, the present invention relates to a magnetorheological fluid damper. Background technique [0002] The magnetorheological fluid is composed of fine soft magnetic particles dispersed in the carrier liquid with low magnetic permeability, forming a suspension liquid whose shear yield strength can change with the external magnetic field and has controllable rheological properties; under the action of the magnetic field, Magnetorheological fluid can realize the reversible change from Newtonian fluid to Bingham semi-solid within milliseconds, and it can return to its original state after removing the magnetic field. [0003] The damper made of magnetorheological fluid has the advantages of large output, small size, fast response, simple structure, continuously adjustable damping, easy combination with computer, and intelligent control. [0004] Traditional magneto-rh...
