Problems solved by technology

[0002] Instruments, especially precision instruments, often need to be placed in a working environment with minimal vibration. People place a layer of sponge pad under the instrument or design various "passive shock absorbers" to meet the vibration reduction requirements of various instruments. For example, the "pneumatic shock absorber" with the Chinese patent application No. 2009100625007 is one of them. Although this kind of pneumatic shock absorber has a compact structure and adjustable rigidity, it uses inflation and deflation to adjust its vibration reduction. performance, therefore, its vibration damping performance is adjusted roughly, and it is difficult to adapt to the different requirements of different instruments for vibration damping

Embodiment Construction

[0012] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0013] see figure 1 and figure 2 , which is a specific structure of the present invention, a single-rod airbag magneto-rheological shock absorber, which includes a working cylinder 5 made of non-magnetic materials, a damping rod 2, an electromagnet 14 and an airbag 8, Among them: the airbag 8 is drum-shaped, the upper circular surface 6 and the lower circular surface 11 of the airbag 8 are made of non-magnetic rigid material, and its peripheral surface 8 is made of polymer elastic material, and the airbag 8 is filled with a certain pressure of gas 12. The working cylinder 5 is fixed with an end cover 4 and an end cover 10 at the upper and lower ends of the cylinder 7. There is a hole in the center of the upper end cover 4, and a sliding bearing 3 is installed in the hole. The inner diameter of the working cylinder 5 is larger than The outer diameter of the ...

Abstract

The invention discloses a single-rod air bag type magnetorheological damper, which comprises a working cylinder, an electric magnet, a damping bar and an air bag, wherein the working cylinder is cylindrical, and an end cover is respectively fixed on the upper end and the lower end of the working cylinder; a hole is arranged in the centre of the upper end cover and a sliding bearing is arranged inside the hole; the inner diameter of the working cylinder is larger than the outer diameter of the air bag; the distance between the upper end cover and the lower end cover of the working cylinder is greater than the height of the air bag; the air bag is installed on the bottom inside the working cylinder; one end of the air bag is fixed with the lower end cover of the working cylinder, and the other end of the air bag is fixed with one end of the damping bar; and the other end of the damping bar extends out of the interior of the working cylinder through a bearing on the upper end cover of the working cylinder; a magnetorheological fluid injected in the working cylinder is higher than the air bag and the height of the magnetorheological fluid injected in the working cylinder is less than the distance between the upper end cover and the lower end cover of the working cylinder; and the electric magnet is fixed on the outer circle of the working cylinder.

Description

technical field [0001] The invention belongs to a shock absorber, in particular to a single-rod airbag type magneto-rheological shock absorber. Background technique [0002] Instruments, especially precision instruments, often need to be placed in a working environment with minimal vibration. People place a layer of sponge pad under the instrument or design various "passive shock absorbers" to meet the vibration reduction requirements of various instruments. For example, the "pneumatic shock absorber" with the Chinese patent application No. 2009100625007 is one of them. Although this kind of pneumatic shock absorber has a compact structure and adjustable rigidity, it uses inflation and deflation to adjust its vibration reduction. Therefore, its vibration damping performance is adjusted roughly, and it is difficult to adapt to the different requirements of different instruments for vibration damping. Contents of the invention [0003] In order to overcome the lack of rough...
