Magneto-rheological clutch with driving disc of groove structure

The invention discloses a magneto-rheological clutch with a driving disc of a groove structure. The magneto-rheological clutch comprises a main driving disc and an auxiliary driving disc, and a liquid medium containing ferromagnetic suspension particles is arranged between the main driving disc and the auxiliary driving disc; and the opposite faces of the main driving disc and the auxiliary driving disc are inner surfaces, a groove is machined in the inner surface of one of the main driving disc and the auxiliary driving disc, and no groove exists in the inner surface of the other opposite driving disc. The magneto-rheological clutch has the beneficial effects that the grooves are formed in the driving disc, so that the shear stress of the magneto-rheological clutch can be effectively enhanced, meanwhile, the surface heat dissipation area of the driving disc is increased, and therefore the comprehensive optimization effects of enhancing the shear moment, enhancing the heat dissipation capacity and reducing th
