In this article, a novel electromagnetic-frictional integrated brake is proposed, and its\nstructure and working principle are introduced. The geometric model and mathematical models of\nintegrated brake were established, and the multi-field coupling mechanism of integrated brake were\nanalyzed. With BYD Qin as a reference vehicle, the boundary conditions of thermal load and force\nload of integrated brake were determined according to its structure and performance parameters.\nBased on the COMSOL software, numerical coupling calculations of electric, magnetic, thermal, and\nsolid fields of integrated brake were carried out respectively in the emergency and downhill braking\nat a constant speed. The axial, circumferential, and radial temperature distributions of integrated\nbrake disc were analyzed respectively, and they were compared with those of the traditional friction\nbrake disc. The analysis results show that the proposed integrated brake can effectively improve the\nheat fading resistance of automotive brake during emergency and continuous braking. Under the two\nbraking conditions, the temperature rise of friction brake was faster than that of an electromagnetic\nbrake, and the effect of the electromagnetic brake on temperature rise of integrated brake was small.
