Magneto-rheological clutch driven disc with turning groove structure

The invention discloses a magneto-rheological clutch driven disc with a turning groove structure. The magneto-rheological clutch driven disc comprises a driven disc body. Grooves with a turning direction are formed in the working surface, opposite to a main driving disc, of the driven disc body, and the turning direction of the grooves is consistent with the rotating direction of the main driving disc. The magneto-rheological clutch driven disc has the beneficial effects that the rotating grooves are formed in the working surface of the magneto-rheological clutch driven disc body so that the torque transmission capacity of the driven disc body of a magneto-rheological clutch in the joint state can be enhanced, meanwhile, the flowing resistance of magneto-rheological fluid when the clutch works is reduced, the flowing rate is increased, the convective heat exchange area of the working surface of the driven disc body is increased, heat dissipation is enhanced, then the dual effects of enhancing the transmission
