Problems solved by technology
[0002] In the existing rotary magnetorheological damper, the rotor is placed in the working cylinder, which is also filled with magnetorheological fluid, and the output damping force is adjusted by changing the viscosity of the magnetorheological fluid in the working cylinder. In order to prevent the magnetorheological fluid in the working cylinder from being taken out of the working cylinder with the rotating shaft, a sealing device is usually used between the working cylinder and the rotating shaft to solve the dynamic sealing problem of the rotating shaft, such as the Chinese patent application number: 200910251079.4 "A screw-type magnetorheological rotary damper" and Chinese patent application number: 200510040890.X high-performance multi-plate rotary magnetorheological damper; because magnetorheological fluid is added with various components in mineral oil Therefore, it is very difficult to dynamically seal it. Once the leakage of the magneto-rheological fluid occurs, the performance of the rotary magnetorheological damper will be degraded, and the rotary magnetorheological damper will be severely damaged. Therefore, the dynamic sealing problem of magnetorheological fluid has become the main obstacle in the industry to improve the service life of magnetorheological dampers
