The invention discloses a low-floor wheel edge distributed electric drive axle housing which comprises an axle housing body, a wheel edge speed reducer and a motor shell are arranged at the two ends of the axle housing body respectively, the axle housing body comprises an axle housing body, an axle housing box cover connected with the axle housing body is arranged at the top of the axle housing body, and a motor oil inlet and a speed reducer oil inlet are formed in the side walls of the two ends of the axle housing body respectively. An oil pump communicated with the axle housing body is arranged on the front wall of the axle housing body and connected with a left oil conveying pipe and a right oil conveying pipe. According to the axle housing, the oil tank and the lubricating system are integrated, oil in the left and right wheel side motors and the speed reducer flows into the oil tank of the axle housing body directly through gravity and then is pumped to the motor cooling oil system and the lubricating system of the speed reducer through the oil pump, the use requirement of a low-floor type public bus is met, and the service life of the low-floor type public bus is prolonged. And active lubrication of an oil cooling motor and a speed reducer is achieved on the low-floor wheel edge distributed electric drive axle, and the requirements for high integration efficiency, high torque density, low energy consumption and low cost of a new energy commercial vehicle are met.
