The invention relates to the technical field of axles, in particular to a large-tonnage steering axle which comprises an axle body serving as a whole component carrier, hubs are installed on the two sides of the axle body, bearings are fixedly installed on the two sides of the axle body, and a left shaft head assembly and a right shaft head assembly which are used for improving the bearing capacity are arranged on the two sides of the axle body respectively. A driving assembly used for driving a vehicle to steer is arranged on the axle body, steering arms are installed on the two sides of the axle body, the left shaft head assembly comprises a steering shaft head arranged on the axle body, the outer side of the steering shaft head is sleeved with a bearing check ring matched with a bearing, and a steering shaft head transition sleeve is fixedly connected to the steering shaft head. Reinforcing ribs are fixedly connected to the steering shaft head transition sleeve, and hexagonal head bolt fine threads are fixedly connected to the end of the steering shaft head. By arranging the left axle head assembly and the right axle head assembly and using a special structure and a heat treatment process, the large-tonnage bearing requirement is met, and large-tonnage transportation is achieved without increasing the size of the axle body.
