TIRE SENSOR

摘要

A tire monitoring device (10) for monitoring various tire conditions of a tubeless tire mounted on a vehicle wheel having a recessed portion of the wheel and a wheel rim (12) defining the recessed portion, including a composite wheel having at least one wire free transmitter and a receiver incorporated into and embedded into the surface of the composite wheel in the recessed portions of the wheel. The transmitter and the receiver will monitor, transmit and receive signals about the tire condition, including tire pressure and temperature. Also included is an embedded antenna (20) permanently incorporated into the recessed portion of the composite wheel, such that the antenna (20) becomes part of the wheel, with an antenna winding length of from about 0.5 to about 5.0 meters long. Other embodiments include the use of a toroidal antenna in the recessed portion of the wheel.
