Abstract
Device for attenuating the rolling noise of vehicles, mounted on a component (3) connected to the wheel. The device includes an annular mass (5) coaxial with the wheel shaft (2) and several actuators of the automatically-controlled linear motor type (6 to 8), acting radially between the mass (5)and the component (3). The motors (6 to 8) are variable-reluctance motors. The device also includes elastic members (9) around the shaft (2) and capable of withstanding the static loads exerted between the inertial mass or masses (5) and the said component (3). The actuators and their powering alternators may be housed in the wheel rims.
