The invention belongs to the technical field of vehicles, and discloses a hub reduction axle. The hub reduction axle comprises a hub reduction gear shell; an axle housing shaft head which is arrangedin the hub reduction shell in a penetrating manner; a half-axle assembly which comprises a spline shaft, an axle tube and a sun gear, wherein the axle tube penetrates through the axle head of the axlehousing, the axle tube is of a hollow structure, the spline shaft penetrates through one end of the axle tube, the sun gear penetrates through the other end of the axle tube, the spline shaft is connected to a half-axle gear of the differential mechanism, and the sun gear is arranged in the hub reduction gear shell; a hub assembly which comprises a housing, an inner bearing and an outer bearing,wherein the housing is arranged in the hub reduction gear shell, the inner bearing and the outer bearing are both arranged in the housing and arranged outside the axle housing shaft head in a sleevingmode, and the end face of the inner ring of the inner bearing and the end face of the inner ring of the outer bearing abut against each other; a gear ring assembly which is arranged on the axle housing shaft head in a sleeving manner; and a planet gear which is meshed with the sun gear and the gear ring assembly. The hub reduction axle meets the requirement for light weight, and the production cost is saved.
