Wheel rim coatings to heat the tyres
Although thing had been known for a long time、Recent infrared thermal image、It has been shown the real effect of the rim coating agent to manage the tire temperature。This coating agent is in the Avanti wheel of the Mercedes、It was first taken in conjunction with the depression of the internal rim。after that、Red Bull also admitted that you are using the same process to OZ Racing's wheel。However, if they are、I had made a groove instead of a recess in the internal wheel。on the other hand、Ferrari has also been said to be coated with OZ Racing's wheel。
The recently、Black coating agent is in the near Sassuoro of ItalyNanopuromu, Inc.ProductsPorishiruIt was found that the。this is、It is a solvent type paint containing a polymer of silicon、mainly、It is designed to protect all types of material to surface friction。This product is usually、9It is sprayed to form a few microns of film to reach a hardness of H。This product fills a small gap of imperfect surface of the wheel、It is a very smooth surface、It might help to suppress turbulence within the wheel。
However、The team is interested in this product is black。Because、Rim of the brake exhaust heat、This is because help to capture the magnesium alloy wheel from the rim。Since a rim itself very high thermal conductivity、Quickly spread throughout the body when the heat is conducted to the metal。Another part is also transmitted to the tire through the tire bead。as a result、Team is maintained at a temperature that was more constant the tire、It is possible to suppress a sudden drop in tire temperature even when running a long straight。By warming the rim properly、The temperature of the tire wall is maintained、It is prevented that the tire cools suddenly。Finally、Because the tire does not decrease the temperature than in the case of no treatment、Grip is high at the time of turn-in。
Infrared thermal images in the figure、This process indicates whether the function how admirably in Reddobuburu Racing。The three images are、It was taken from the vehicle-mounted camera of the circuit-of-the-in the United States of America GP in Q1 of Sebastian Vettel machine。In the first one approach to turn 19、2Th in the turn-in point of turn 19、And the third piece is the end of the pit straight、It was taken before braking。In all the three images、Temperature of the rim is relatively high、Also at the end of the straight、Tire it can be seen that is still warm the entire tread width。A similar image Mercedes also similar、Effect was not as pronounced as this。Also、Ferrari wheel as seen by the infrared camera is no warm、That the temperature than the other team is low it has been suggested。
New or "conservative" operating temperature of the tire of Pirelli's what extent is not yet known、But this technology is likely to continue to use even 2014。further、Nanopuromu Inc.、It has been referred to the possibility of the use of a coating agent with respect to the composite and compound、It is almost certainly also be used for engine parts。
