TIRE BLOWOUT SAFETY HUB

A safety hub against tire bursts is provided according to the present application, which includes a hub body. The hub body includes an outer annular surface, a first side surface, and a second side surface. The first side surface and the second side surface are oppositely arranged on two sides of the outer annular surface. The two sides of the outer annular surface are oppositely provided with a first wheel flange and a second wheel flange. A tire mounting seat is formed between the first wheel flange and the second wheel flange, and an anti-detachment collar is provided on the tire mounting seat. The anti-detachment collar is an annular protruding ring arranged along the outer annular surface. The anti-detachment collar is concentric with the outer annular surface. The surface of the anti-detachment collar is provided with a toothed structure which includes multiple protruding teeth and recesses. The protruding teeth and the recesses are alternately arranged. The protruding teeth are protrusions extending outward from the surface of the anti-detachment collar. The recesses are grooves recessed inward from the surface of the anti-detachment collar. The overall diameter of the protruding teeth is greater than the diameter of a tire bead adapted to the tire mounting seat. If the tire with the safety hub against tire bursts bursts, the anti-detachment collar can lock the tire and support the tire bead simultaneously, so that the burst tire can continue to rotate with the hub, thereby reducing the amplitude of deviation of the automobile.
