Apparatus for covering disc wheel for motor vehicle

摘要

An apparatus for covering a disc wheel supporting a tire for a motor vehicle has a wheel cover mounted on the disc wheel and covering an outer side of the disc wheel, and at least one ventilation opening in the wheel cover for communicating the inside of the wheel cover with the atmosphere. The apparatus is provided with a closing plate for closing the ventilation opening when a temperature inside the wheel cover is not more than a predetermined temperature and opening the ventilation opening when the temperature inside the wheel cover is more than the predetermined temperature. A heat sensing member, which may be made of a shape memory effect alloy is connected to the closing plate and deforms when the temperature inside the wheel cover is more than the predetermined temperature so as to displace the closing plate away from the opening to open the opening.
