Magnetorheological Shock Absorber with Bellows Deformation Suction Discharge

Abstract

The present invention provides a magneto-rheological shock absorber with bellows deformation suction and discharge, including a working cylinder, a shock-absorbing piston, a floating piston, a piston rod and a shock-absorbing spring; the floating piston and the shock-absorbing piston are arranged in the working cylinder Inside the barrel and the floating piston is located between the bottom of the working cylinder and the damping piston, a closed space is formed between the bottom of the working cylinder and the floating piston and filled with gas; the damping piston is provided with an excitation coil, and the damping piston It is fixedly connected with the piston rod, and the shock-absorbing spring is outside the working cylinder; it also includes a bellows, one end of the bellows is fixedly connected with the floating piston, and the other end of the bellows is fixedly connected with the shock-absorbing piston. The side wall is provided with a liquid flow hole. Through the above structure, the stirring of the magnetorheological fluid can be automatically completed when the shock absorber is in use, thereby effectively avoiding the decline in damping performance caused by the settlement of the magnetorheological fluid, and no external energy is required. Or control equipment, simplify the structure of the shock absorber, and reduce manufacturing and use costs.

Description

technical field [0001] The invention relates to a magneto-rheological shock absorber, in particular to a magneto-rheological shock absorber with a bellows deformation suction row. Background technique [0002] The magnetorheological damper (MRD) is a vibration reduction device based on the magnetorheological effect, which is widely used in vehicles, construction, sports equipment, medical prosthetics and other fields; due to its adjustable damping force, it can perform semi-active control, Therefore, it has attracted the attention of researchers. However, due to the sedimentation problem of magnetorheological fluid, the development and application of magnetorheological dampers are greatly restricted. [0003] In the prior art, the magnetorheological fluid settlement problem is solved by improving the magnetorheological fluid itself and the structure of the shock absorber, but the improvement of the magnetorheological fluid itself can only delay the magnetorheological fluid ...

However, due to the sedimentation problem of magnetorheological fluid, the development and application of magnetorheological dampers are greatly restricted.

[0003] In the prior art, the magnetorheological fluid settlement problem is solved by improving the magnetorheological fluid itself and the structure of the shock absorber, but the improvement of the magnetorheological fluid itself can only delay the magnetorheological fluid settlement However, the improvement of the structure of the current shock absorber is relatively complicated and the manufacturing cost is high, but the shock absorber cannot solve its settlement problem after being placed for a long time, thus Seriously affect the damping performance and shock absorption effect of the shock absorber
