Vehicle hub temperature monitoring device

The utility model belongs to the technical field of hubs, and particularly relates to a vehicle hub temperature monitoring device which comprises a hub, a limiting box is arranged at the outer side end of the hub, a limiting device is arranged in the limiting box, and the limiting device comprises a limiting toothed plate, a toothed roller, a toothed bar and a pressing plate. According to the vehicle hub temperature monitoring device, in order to monitor the temperature of a hub through a temperature sensor, a limiting box is aligned with the inner side of a fixing ring to rotate, the temperature sensor can be tightly attached to the surface of the hub, and when the hub rotates, a pressing plate has centrifugal force, so that the pressing plate tends to be away from the fixing box; and the temperature sensor senses the temperature of the hub, but when the temperature sensor senses that the temperature is too high, the information processing module processes the information after receiving an electric signal o
