[0002] At present, magnetorheological fluid is a suspension including carrier liquid, magnetizable particles, surfactants, etc. In the absence of a magnetic field, the magnetorheological fluid can flow freely. However, after the addition of a magnetic field, the magnetizable particles in the carrier liquid instantly obtain a dipole moment and are arranged into a chain structure, causing the magnetorheological fluid to change from a free-flowing state to a semi-solid state, thereby changing the viscosity of the magnetorheological fluid.

[0020] In the present embodiment: the positions of the adjustable tray 3 and the locking ring 4 on the screw barrel 2 can be changed through the thread of the screw barrel 2, which can improve flexibility and adjust the height of the vehicle body according to road conditions. Compared with the air spring shock absorber to adjust the height of the vehicle body, the adjustable tray 3 shock absorber only needs to add a threaded sleeve, an adjustable tray 3, and a locking ring 4 to adjust the height of the vehicle body. The auxiliary spring 7 between the main clamping plate ring 5 and the auxiliary clamping plate ring 6 can make the threaded rotation of the screw barrel 2 more stable and convenient.

[0021] Specifically, two guide mechanisms 8 are fixedly embedded in the inner wall of the oil storage cylinder 1 , and piston rods 9 are slidably embedded in the inner walls of the two guide mechanisms 8 .

[0022] In this embodiment, two guide mechanisms 8 can assist the piston rod 9 in sliding and fill the magnetic fluid therebetween.

[0023] Specifically, a damping unit 10 is fixedly sleeved on the outer wall of the piston rod 9 .

[0024] In this embodiment, the damping unit 10 moves in the magnetic fluid and is affected by the magnetic fluid.

[0025] Specifically, the space between the two guide mechanisms 8 and the oil storage cylinder 1 is filled with magnetic fluid, and the outer wall of the damping unit 10 is embedded in the magnetic fluid.

[0026] In this embodiment, through the magnetic fluid, the magnetizable particles in the carrier fluid instantly obtain a dipole moment and are arranged into a chain structure, so that the magnetorheological fluid changes from a free-flowing state to a semi-solid state, thereby changing the viscosity of the magnetorheological fluid.

[0027] Specifically, a fixed bottom cover 11 is fixedly embedded in the bottom of the inner wall of the oil storage cylinder 1 , and a threaded spring 12 is fixedly provided between the fixed bottom cover 11 and one of the guide mechanisms 8 .

[0029] When in use, the thread of the screw barrel 2 can change the position of the adjustable tray 3 and the locking ring 4 on the screw barrel 2, so as to improve flexibility and adjust the height of the vehicle body according to road conditions. Compared with the air spring shock absorber to adjust the height of the vehicle body, the adjustable tray 3 shock absorber only needs to add a threaded sleeve, an adjustable tray 3, and a locking ring 4 to adjust the height of the vehicle body. The auxiliary spring 7 between the main clamping plate ring 5 and the auxiliary clamping plate ring 6 can make the thread rotation of the screw barrel 2 more stable and convenient. The two guide mechanisms 8 can assist the piston rod 9 to slide and fill the magnetic fluid between them. The damping unit 10 moves in the magnetic fluid. Under the influence of the magnetic fluid, the magnetizable particles in the carrier liquid instantly obtain a dipole moment and are arranged into a chain structure, so that the magnetorheological fluid changes from a free-flowing state to a semi-solid state, thereby changing the viscosity of the magnetorheological fluid. The fixed bottom cover 11 can close the bottom of the oil storage cylinder 1, and the threaded spring 12 can make the fixed bottom cover 11 and one of the guide mechanisms 8 elastic.
