Abstract

The invention discloses a double main spring hydraulic suspension comprising a permanent magnetorheological elastomer. The double main spring hydraulic suspension comprises a shell, a rubber basementmembrane, a first main spring, a second main spring and a bolt, wherein the rubber basement membrane is arranged at the bottom of the shell; the first main spring is arranged at the top opening position of the shell, and the middle part of the first main spring is provided with a through hole; the second main spring is arranged in the through hole of the first main spring and comprises a first permanent magnet arranged on the top of the through hole, a second permanent magnet arranged at the bottom of the through hole, and a magnetorheological elastomer arranged between the first permanent magnet and the second permanent magnet; and the bolt is connected to the first permanent magnet through a preloaded spring, and can be used for adjusting the distance between the first permanent magnet and the second permanent magnet. On the basis that liquid damping energy consumption is generated by oscillatory movement of liquid columns in a traditional hydraulic suspension, another energy consumption type is increased, so that the vibration and noise reduction performance of the suspension is improved.

Description

technical field [0001] The invention relates to the design field of vibration isolation devices, in particular to an intelligent magnetorheological elastomer material applied to a liquid damping rubber mount of an automobile powertrain. Background technique [0002] With the reduction of the weight of the automobile body and the increase of the specific power of the powertrain, the problem of vehicle vibration and noise caused by the excitation of the automobile engine is becoming more and more serious. Therefore, it is of great practical engineering significance to further improve the performance of the automobile powertrain mount. [0003] Since rubber mounts were used in large quantities in automobiles in the 1920s, the structure of mounts has changed from rubber to hydraulic, and the control method has changed from passive control to semi-active / active. Its performance has been continuously improved, and its cost has also increased. The performance of the active mount is...
