Brake cooling mechanism of four-wheeled vehicle

摘要

A brake cooling system for a four-wheeled drive automobile effectively releases frictional heat generated in a braking apparatus from a surface of a casing of the braking apparatus, and has enough height of a body of the automobile relative to ground level. The brake cooling system includes an air discharging duct which is connected to an air discharging outlet of a belt cover covering an automatic V-belt transmission. The duct extends to a vicinity of the braking apparatus so as to supply air towards the braking apparatus. The braking apparatus is positioned in front of a final reduction gear for rear wheels, and the casing of the braking apparatus is a common casing inside of which the braking apparatus and the final reduction gear are accommodated.
