The invention discloses a gear hub of a gauge-changeable bogie. The gear hub comprises a gear hub body with an inner hole, and the gear hub body is installed on a driving shaft sleeve composed of driving wheels. A gear hub spline is arranged in the inner hole of the gear hub, a gear ring installation face is arranged in the middle of the gear hub, the outer surfaces of the two sides of the gear ring installation face are each provided with a gear box bearing mounting surface, and a gear hub supporting face and a gear hub locking boss are arranged on the outer surface of one end of the gear hub. The gear ring mounting surface is used for mounting an outer sleeve gear ring; and the gear box bearing mounting surface is used for mounting a rolling bearing. The gear hub can be externally connected with a driving gear box, so that the gauge-changeable wheel set has the driving capacity.
