The invention relates to an automobile duplex drive axle which comprises an intermediate axle assembly, a motor, a double-speed reducer, an inter-axle differential mechanism and a driven part. The motor can drive the double-speed reducer to rotate around a first axis, the double-speed reducer can drive the inter-axle differential mechanism to rotate around a second axis, the inter-axle differential mechanism can drive the driven part to rotate around a third axis, and the double-speed reducer and the driven part are arranged on the two sides of the inter-axle differential mechanism in the first direction. The middle axle assembly is connected to the rear axle assembly through the transmission shaft; the double-speed reducer, the inter-axle differential mechanism and the driven piece are all configured to be of a cylindrical gear structure. The first axis, the second axis and the third axis are parallel to each other, and the first direction is perpendicular to the first axis. A cylindrical gear structure is adopted, so that the structural layout of the automobile duplex drive axle is compact, the consumption of axial force of the automobile duplex drive axle is reduced, and the transmission efficiency is improved.
