The utility model discloses a forced-lubrication oil pump of a perforation double drive axle; an inner cavity of a pump body is provided with an outer rotor which is externally provided with a spring piece and internally provided with an inner rotor assembly; and an end cover is arranged outside the inner rotor assembly and positioned by a snap spring. When in use, the oil pump is driven to work by the rotation of a gear arranged at the rear side. As a forced-lubrication system is adopted, the structure of a perforation axle speed reducer can be optimized, oil supply can be realized both by positive and negative rotation, the lubrication of an interaxial differential assembly can be enhanced, the strength of the interaxial differential assembly is improved, and the failure of an interaxial differential mechanism caused by the poor lubrication can be reduced.
