The invention discloses an automobile brushless drive-by-wire electromagnetic clutch which comprises brushless electromagnets, thrust pressure plates, driven internal spline hubs, drive-by-wire driving discs, eccentric sphere arm hollow wheel discs, eccentric sphere arm pins, eccentric sphere arms, eccentric spheres, magnetic conductive force transferring discs, a driven shaft, a driven shaft connecting disc and a driving shaft, wherein during high speed operation and after the brushless electromagnets are electrified, each of the eccentric sphere arms and the eccentric spheres generates a centrifugal force, the eccentric sphere arms and the eccentric spheres perform circular movement around the eccentric sphere arm pins along the smooth surfaces of the thrust pressure plates under the effect of the centrifugal forces; the thrust pressure plates are pushed by component forces of the centrifugal forces in the central axis directions of the eccentric sphere arm hollow wheel discs, so that channel steel sheets with external splines and grooved friction plates with internal splines can be compressed tightly to realize the engagement of the clutch. The automobile brushless drive-by-wire electromagnetic clutch has the advantages of smooth clutch engagement without impact and big transmission torque, and is suitable for high speed operation.
