Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] Such as figure 1 As shown, the stepped hybrid magnetorheological shock absorber includes a working cylinder 1, a piston rod 2, a piston body 3, a magnetorheological fluid 4, a permanent magnet ring 6, a coil I7, and a coil II8, and is characterized in that :

[0030] The piston body 3 is in the shape of a stepped shaft, and the middle one is a primary shaft 10 with the largest radius. There are more than one set of secondary shafts arranged on the left and right sides of the primary shaft 10, with the primary shaft 10 facing the left and right sides, The radius of each secondary axis decreases in turn;

[0031] The left and right end walls of the working cylinder 1 are respectively provided with piston rod holes, and the two ends of the piston rod 2 pass through the left and right end surfaces of the working cylinder 1 respectively through the piston holes, and can...

Abstract

The invention aims to provide a stepped hybrid magneto-rheological damper which comprises a working cylinder, a piston rod, a piston body, magneto-rheological fluid, a permanent magnet ring, a coil Iand a coil II. The piston body is in a stepped shaft shape. The damper can solve the problems of small existing damping force and the like, and simultaneously achieves the advantages that the volume of the magneto-rheological fluid for working is reduced, the magneto-rheological damping force is greatly improved, the consumption of the required magneto-rheological fluid is reduced, and the magneto-rheological effect is remarkable.

Description

technical field [0001] The invention belongs to the field of magnetorheological technology, and in particular relates to a stepped hybrid magnetorheological shock absorber. Background technique [0002] The magnetorheological shock absorber is a new type of shock absorber that uses the controllable fluid of magnetorheological fluid. Under different magnetic fields, the shear yield strength of the magnetorheological fluid is different, and the shear force that forces the magnetorheological fluid to flow is also different, that is to say, the damping force provided by the magnetorheological shock absorber is variable. Therefore, by controlling the external magnetic field, the purpose of adjusting the damping force of the magneto-rheological shock absorber can be achieved. It is precisely because the magneto-rheological damper has this important engineering application value that it has caused extensive research on the magnetorheological damper in the industry.
