Coaxial electric drive axle with differential lock

The invention discloses a coaxial electric drive axle with a differential lock, which enables a motor to transmit power of the motor to a differential mechanism through a planetary reducer and transmit the power to wheels on two sides. The drive axle is characterized in that the drive axle motor is fixed with a sun gear of the planetary reducer through a spline, power is transmitted to the planetary reducer and then transmitted to the differential mechanism, and the differential mechanism outputs the power to wheels at the two ends through half shafts; a differential lock and a planet carrier are both provided with end face teeth, the differential lock is inserted into a half axle wheel carrier, when a vehicle runs normally, an electromagnetic controller attracts the differential lock to be recovered, and the differential lock is separated from the end face teeth of the planet carrier; when a vehicle slips, the differential lock end face teeth are combined with the planet carrier end face teeth, the planet ca
