Magnetorheological damper and magnetorheological fluid perfusion method

Abstract

The invention relates to a magnetorheological damper and a magnetorheological fluid perfusion method. The magnetorheological damper includes a rotor, and the rotor is connected to a transmission shaftby a key. A front end cover and a rear end cover are respectively arranged on the front and rear sides of the rotor, and the outer part of the rotor is provided with an outer casing, the front end cover and the rear end cover and the outer casing are fixed together to form a stator; the front end cover and the rear end cover are distributed in the axial direction of the transmission shaft; the front end cover and rear end cover are internally correspondingly wound with a front excitation coil and a rear excitation coil, a front isolation magnetic ring is set between the front end cover and the front side face of the rotor, and a rear isolation magnetic ring is set between the rear end cover and the rear side face of the rotor; the outer casing is provided with at least three liquid injection holes, each liquid injection hole is sealed by a sealing cover. According to the magnetorheological damper and the magnetorheological fluid perfusion method, the magnetorheological damper is provided with at least three perfusion holes in an appropriate position. On the basis of the existing technical scheme, the position and number of the perfusion holes are optimized, at least one perfusionhole can be used as an exhaust hole in the process of liquid injection is ensured, and design of the position of the perfusion holes is reasonable.

Description

technical field [0001] The invention relates to a magneto-rheological damper and a magnetorheological fluid filling method thereof, in particular to a rotary magnetorheological damper and its magnetorheological fluid, which have the characteristics of large damping torque and high requirements for filling adequacy. Easy perfusion method. Background technique [0002] The magnetorheological fluid perfusion gap of the magnetorheological damper is generally designed between 1-2mm. The magnetorheological damper designed with a large torque needs to be perfused with more magnetorheological fluid. Since the magnetorheological fluid perfusion space gap is small, and Magneto-rheological fluid has high viscosity and poor fluidity, resulting in gaps remaining after perfusion, making it difficult to fully perfuse, and air bubbles are likely to remain in the magnetorheological fluid cavity, which seriously affects the design performance of the magnetorheological damper such as output an...
