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 carrier and the differential lock are fixed into a whole, then the planet carrier and the half axle wheel carrier are combined into a whole, the differential mechanism is locked, and power is evenly output to the two sides.
本发明公开了一种带差速锁的同轴式电驱动桥,使得电机通过行星减速器将电机的动力传输到差速器,并将动力传递向两侧车轮;其特点是,该驱动桥电机与行星减速器的太阳轮通过花键固定,将动力传输到行星减速器,再传递到差速器,差速器通过半轴将动力输出到两端车轮;差速锁与行星架均具有端面齿,差速锁穿插在半轴轮架上,车辆正常行驶时电磁控制器吸附差速锁回收,差速锁与行星架端面齿分离;当车辆出现打滑状况时,差速锁端面齿与行星架端面齿结合,行星架与差速锁固定为一体,进而与半轴轮架结合为一体,进而实现将差速器锁死,实现动力均匀向两侧输出。
