The invention discloses an electronic control multi-plate-type self-locking drive axle. The electronic control multi-plate-type self-locking drive axle comprises a drive axle box with a first differential shell body and a drive axle box cover. The first differential shell body is internally provided with a left half axle gear, a right half axle gear, a planet gear and a transmitting gear. The drive axle box is internally provided with an input gear meshed with the transmitting gear. The right half axle gear is provided with a second differential shell body rotationally connected with the drive axle box cover and provided with a differential shell cover in a sealed manner. A work friction set is arranged between the right half axle gear and the second differential shell body, and a plane spherical-surface cam set abuts against the right end of the work friction set. A control friction set is arranged between the plane spherical-surface cam set and the second differential shell body. A pushing disc with a plurality of pushing rods and reset springs abuts against the right end of the differential shell cover, the pushing rods leftwards penetrate the differential shell cover and to be matched with the control friction set in an abutting manner, and the reset springs are arranged between the differential shell cover and the pushing disc. A plane cam set abuts against the right end of the pushing disc, and a driving mechanism for allowing the plane cam set to rotate in the circumferential direction is arranged at the outer end of the plane cam set. By means of the electronic control multi-plate-type self-locking drive axle of the structure, the sliding limiting effect is good, and the defect that locking can not be achieved easily during high-speed slipping is overcome.
