Vehicle wheel with sub air chamber and pressure sensor

摘要

A wheel body includes a wheel body including a disk and a rim fixed to an outer circumference of the disk for supporting a tire for the vehicle; an air pressure sensor unit for detecting a pressure in an air chamber in the tire with transmitter; a sub air chamber member on the rim for reducing a magnitude of a resonance sound generated by an air column defined by the air chamber defined by the rim and the tire. The air pressure sensor unit and the sub air chamber member are disposed in a circumferential direction of the wheel so as to cancel out one unbalance mass distribution of the vehicle wheel in the circumferential direction of the wheel caused by disposing the air pressure sensor by another unbalance mass distribution of the wheel in the circumferential direction caused by disposing sub air chamber member.
