Device for sound insulating a wheel, in particular a wheel of a motor vehicle

摘要

Device for sound insulating a wheel, in particular a wheel of a motor vehicle. The wheel comprises a circular central body, a substantially cylindrical rim including a rear part and a front part, the parts being separated by the plane of the body which extends substantially perpendicularly to the axis of rotation of the rim. The device includes at least one substantially cylindrical ring disposed concentrically relative to the rim and including at least one layer of a viscoelastic material, and at least one way to mechanically couple the cylindrical ring to the rim, the mechanical coupling ensuring a binding of the ring on the cylindrical parts of the rim.
