Vehicle wheels cooling device, has blades integrated with tapered ring to form crown whose symmetrical axis is merged with rotational axis of wheel, and plate having surface identical to that of rim

摘要

The device has blades (3) integrated with a tapered ring (31) to form a crown (30) whose symmetrical axis is merged with the rotational axis of a wheel. Inner surface (311) of the ring cooperates with the blades and with the surface of a rim (2), to create a centrifugal fan directing air flow outside the device. A plate (4) includes surface identical to that of the rim.
