Abstract

The invention discloses a magnetorheological damper piston assembly with a sedimentation active dispersion device, which includes a working cylinder, a piston rod and a piston assembly; the working cylinder is equipped with magnetorheological fluid; the upper end of the piston rod is inserted into Inside the working cylinder, the part where the lower end passes through the working cylinder is provided with an oil seal; the piston assembly includes a rotor, a stator, a top cover and a bottom cover; the outer circumferential wall of the rotor is provided with spiral ribs; the rotor The stator is loosely sleeved on the piston rod and located inside the working cylinder; the stator is sleeved on the rotor and located inside the working cylinder; a damping gap is formed between the stator and the rotor; the top cover is sleeved on the piston rod and located inside the working cylinder inside; the bottom cover is located in the working cylinder; the present invention causes the magnetorheological fluid to rotate and flow axially in the working cylinder through the damping gap through the rotation of the spiral ribs on the rotor, which not only realizes that the magnetorheological fluid settles after The redispersion of the magneto-rheological damper also helps the energy recovery of the magneto-rheological damper during normal operation.

Description

technical field [0001] The invention relates to the field of magnetorheological dampers, in particular to a magnetorheological damper piston assembly with a settlement active dispersing device. Background technique [0002] Magnetorheological fluid is a suspension formed by mixing tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic liquid. This kind of suspension exhibits low-viscosity Newtonian fluid characteristics under the condition of zero magnetic field; while under the action of strong magnetic field, it presents high-viscosity, low-fluidity Bingham fluid characteristics. In the case of zero magnetic field, the magnetorheological fluid behaves as a liquid with good flow performance, and its apparent viscosity is very small; under the action of a strong magnetic field, the apparent viscosity can increase by more than two orders of magnitude in a short time (milliseconds), and presents Solid-like properties; and thi...
