The present application relates to a wheel with a sound absorber, the sound absorber being mounted in a wheel air chamber to reduce acoustic resonance, wherein the sound absorber is configured as a flat hexahedral box resonator and fastened to a wheel hub through a band, a first positioning mechanism is provided between the hub and the box resonator to fix the relative positions of the hub and the box resonator, and a second positioning mechanism is provided between the box resonator and the band to fix the relative positions of the box resonator and the band. According to the technical solution of the present disclosure, the resonator is positioned and fixed more reliably on the wheel, and the wheel is simple and economical in manufacturing, and convenient and controllable in installation and operation.

An air deflector that is at least partially disposable within a tubeless tire of a bicycle wheel includes a body. The body includes at least one wall defining an air input end and an air output end of the body. The body is attachable to a valve of the tubeless tire at the air input end, such that when air is introduced into the body via the valve, at least some of the air is deflectable by one or more walls of the at least one wall out of the body at the air output end.

An airflow adjusting apparatus to be installed in a vehicle includes an airflow generator and a controller. The airflow generator is provided on an inner surface of a wheel house or on a wheel. The wheel house provides a wheel containing section of a vehicle body. The wheel is contained in the wheel containing section. The airflow generator is configured to generate an airflow that flows from the wheel containing section toward outer side in a vehicle widthwise direction. The controller is configured to control the airflow generator.

A sub-air chamber member includes: a lower surface portion disposed proximate to the outer circumferential surface of the well portion; an upper surface portion disposed radially outside of the lower surface portion; a pair of edge portions engaging with the well portion. A space portion is positioned above the upper surface portion, the space portion being formed by a part of the upper surface portion and an inner wall surface of the well portion. A strong axis of principal axes of a section of the sub-air chamber member perpendicular to an axis of the sub-air chamber member is inclined by a first predetermined angle relative to a wheel width direction Y.

A bicycle wheel sensor is provided and includes a housing configured to be at least partially disposed within a tire of a bicycle wheel. The sensor may be mounted opposite a valve stem location to help balance the bicycle wheel. The bicycle wheel sensor has one or more sensors exposed to the inside of the tire and is configured to provide data obtained from within the tire. The sensor includes an electronic control unit that receives the data from the sensors and transmits the data to a user device via a transceiver.

A variable wheel resonator system for a vehicle can suppress a resonance noise in a wide resonance frequency band occurring during driving of the vehicle by variably controlling an amount of air flowing from a first air chamber of a tire to a second air chamber and then flowing again to the first air chamber through an on/off control of a solenoid valve mounted on a wheel resonator. The system can suppress the resonance noise in the resonance frequency band that differs in accordance with a road-surface input frequency change (road-surface impact change) input to the tire, a driving speed and turning condition change, and a temperature change of an internal air of the tire.
