Electronic limited slip differential mechanism

The invention relates to the technical field of differential mechanisms, particularly to an electronic limited slip differential mechanism. The electronic limited slip differential mechanism comprises a differential mechanism end cover, a needle bearing, an electromagnetic clutch support, an electromagnetic clutch, a magnet, a magnet support, a large piston, a small piston, an internal friction plate, an external friction plate, an air exhaust cock and a thrust unit. The electromagnetic clutch is arranged on the electromagnetic clutch support; the electromagnetic clutch support is mounted on the differential mechanism end cover through the needle bearing; the electromagnetic clutch support is mounted on the differential mechanism end cover through a thrust bearing; the magnet and the electromagnetic clutch are oppositely arranged, and the magnet is connected with the small piston through the magnet support; the large piston is arranged on the right of the small piston; the thrust unit is arranged on the left of the large piston; the right end surface of the large piston abuts against the external friction plate; the external friction plate and the internal friction plate are arranged inside a differential mechanism left casing in a crossed mode; the air exhaust cock is arranged inside the differential mechanism end cover. The electronic limited slip differential mechanism is simple in structure, good in slip limiting effects and short in slip limiting response time.
