Distributed coaxial electric drive axle suitable for new energy commercial vehicle

The invention belongs to the technical field of coaxial electric drive axles, and discloses a distributed coaxial electric drive axle suitable for a new energy commercial vehicle, and the distributed coaxial electric drive axle is composed of an axle housing, a wheel edge motor, a wheel edge transmission system, a disc brake, an upper cross beam and a lower cross beam; the wheel edge transmission system is composed of a first-stage speed reducer assembly, a wheel edge planetary speed reducer and a hub assembly. An output shaft of the motor and a wheel edge output shaft are coaxially designed, the occupied space of a power system is greatly reduced, the weight of the system is reduced, a transmission chain is shortened, the transmission efficiency and NVH are improved, through wheel edge integration, the weight of a driving system is reduced, the arrangement space of power performance is saved, a power transmission chain is shortened, and the transmission efficiency is improved; through the structural design t
