The present invention relates to an electronic differential locking system enabling escape from a slip region of an unpaved, gravel, muddy, or snowy road since both axles (12, 13) and both tires rotate at a 1:1 rotation ratio, or with the same revolutions, which is caused by the operation of an electronic differential locking system (30) to lock (stop) a differential function by the manipulation of a switch (ON/OFF) when an operating vehicle is idling, with its tires stuck, on an unpaved, gravel, muddy, or snowy road. The electronic differential locking system, according to the present invention, comprises: an electromagnet (31) formed inside a differential case (2) and fixed in a connecting groove; and a rotor (34) installed close to the electromagnet (31) and spline-connected to an outer face of a side of an axle shaft (14), to rotate with the axle shaft (14), wherein an outer circumference part (34b) enclosing an outer circumference of the electromagnet (31), a frictional surface (34a) protruding in the direction of a friction member (38), and a protruding part (34e) connected to and supporting an axial bearing (32a) are formed in the rotor (34). The ring-shaped friction member (38) is fixed by multiple bolts (35) on one side edge of a restoring member (36) and a plain washer (39) is installed between a fixing part (36a) of the restoring member (36) and the friction member (38) to improve elastic force of the restoring member (36) and restoring force of the friction member (38). In addition, an alarm (A) is going off at an interval of approximately 60 seconds by turning on (ON) a switch (S) in order not to forget releasing a differential lock. |
