Abstract

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 the highest temperature rise are achieved.

Description

technical field [0001] The invention relates to a clutch, in particular to a magneto-rheological clutch with a transmission disc in a groove structure, which belongs to the technical field of mechanical transmission. Background technique [0002] In recent years, with the development of "smart materials", under the action of an external magnetic field, the physical properties of magnetorheological fluids, such as thermal conductivity, mechanical properties, especially the rapid reversible changes in rheological properties under the action of a magnetic field, make it in mechanical It is widely used in transmission, aerospace, construction, medical and other fields. It is a liquid composed of ferromagnetic particles with high magnetic permeability, carrier liquid and additives mixed in a certain proportion. When there is no external magnetic field, it has good fluidity. When there is a magnetic field outside, the magnetorheological The ferromagnetic particles in the liquid w...
