The invention relates to an explosion-proof hub. The explosion-proof hub consists of a hub 1, sealing gaskets, sealing rings, a tyre burst preventing wheel, a charging connector, an overpressure control valve, a minimum air pressure alarm, a hub 2, and explosion-proof hub connecting and fixing bolts, wherein the tyre burst preventing wheel adopts a multi-piece combining technology, and the explosion-proof hub is divided into a plurality of components, so that each of the components can generate multiple effects; the hub 1, the tyre burst preventing wheel and the hub 2 are combined to form the explosion-proof hub; the explosion-proof hub with a deflection can be obtained by that the structure of the hub 1 is slightly changed, the spoke is moved to the center line of the hub by a distance of a design scheme; the dimensions of the explosion-proof hubs are different, so that according to the size of the tyre burst preventing wheel, the tyre burst preventing wheel is 20-80mm higher than the outer diameter of the explosion-proof hub, and wheel width of the tyre burst preventing wheel is set as 20mm-80mm; the tyre burst preventing wheel is a circular solid wheel, and is mounted in the tyre, and between the hub 1 and the hub 2; and antiskid system mounting holes are formed in the outer side surface of the hub 1 and the outer side surface of the hub 2.
