Abstract

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.

Claims9

Dependent claims

A variable wheel resonator system for a vehicle, the system comprising:

a resonator structured to have a second air chamber formed therein and an air vent formed on one side portion thereof for communication with a first air chamber within a tire, the resonator being mounted on a rim portion of a wheel;
a solenoid valve mounted on a specific position of the resonator and configured to adjust an amount of air flowing from the first air chamber to the second air chamber;
a power supply configured to provide power for a turn-on operation of the solenoid valve;
and
a controller configured to control current being applied from an external power source to the power supply to suit a power supply time for turning on/off the solenoid valve and a periodic signal.
