An electronic limited slip differential

Technical Field The present invention relates to differentials, particularly to an electronic limited slip differential comprising a differential cover, needle roller bearings, brackets electromagnetic clutch, an electromagnetic clutch, the magnet, the magnet holder, the large piston, a small piston, within the friction plate, an outer friction plate, and an exhaust cock thrust unit. An electromagnetic clutch provided to the electromagnetic clutch holder; mounting bracket via an electromagnetic clutch needle bearing on the differential cover; mounting bracket via an electromagnetic clutch thrust bearing on the differential cover. The electromagnetic clutch disposed opposite the magnet, the magnet holder and the magnet are connected by a small piston; the larger piston is provided on the right side of the smaller piston; thrust unit disposed on the left side of the larger piston. A right end surface of the larger piston and the outer friction plate abuts the outer friction plates and inner friction plates arranged in the differential cross left shell; drain cock is provided in the differential end cap. Electronic limited slip differential of the present invention provides a simple structure, good limited slip effect, limited slip short response time.
