Abstract: The present disclosure is a high-stability and large-torque magnetorheological fluid clutch. Firstly, in order to prevent sedimentation of the magnetorheological fluid, blades are installed on the disc body of an input disc. When the clutch operates in a power interruption mode, the blades can stir the magnetorheological fluid, so that the sedimented magnetorheological fluid is uniformly mixed. Secondly, in order to improve the maximum transmission torque of the magnetorheological fluid clutch, an excitation magnetic field is increased in a mode that a permanent magnet and an electromagnet are connected in series. Meanwhile, a third electric push rod is used for pushing the input disc, and the magnetorheological fluid works in a shearing-extruding working mode, so that the yield stress of the magnetorheological fluid is improved. Therefore, the maximum transmission torque of the magnetorheological fluid clutch is improved.
