The invention discloses a coaxial motor drive axle which is characterized in that the coaxial motor drive axle is composed of an axle housing assembly, a two-stage planetary gear reducer assembly, a drive motor, a hub assembly and a brake system, and the axle housing assembly is mainly composed of an axle housing body and a shaft head; the two-stage planetary gear speed reducer assemblies are arranged on the two sides of the shaft head respectively; the driving motor is located in an inner cavity of the axle housing body. The hub assembly is rigidly connected with the secondary planet wheel bracket, is supported on the shaft head through two bearings and can rotate around the shaft head; the brake system is mainly composed of a brake disc and piston type calipers. The coaxial motor drive axle has the two-stage planetary speed reduction function and the braking function, and has the advantages of being good in braking effect, simple in structure, low in cost, easy to maintain and the like.
