Abstract
Disclosed is a vehicle equipped with air-filled tires, wherein heating of the air-filled tires during driving is minimized, and the durability of said tires is increased. Either many dimples are formed on the outside surface of at least one sidewall of the air-filled tires, or at least part of the outside surface of the sidewalls is formed using a good-thermal-conductivity rubber having a thermal conductivity of at least 0.40 W/(m·K). The vehicle is also provided with a cooling device that blows a gas that cools the air-filled tires from the outside.
Claims18
A vehicle having pneumatic tires, wherein
- plural dimples are present on an outside surface of at least one sidewall of each of the pneumatic tires,
- the vehicle includes a cooling device which blows gas for cooling the pneumatic tire from an outside source, and
- wherein said cooling device includes
- a duct which is provided at one end with an air induction port which takes in air and at the other end with an issuing port blows the air toward a brake device, and
- a changeover tool which blows at least a portion of the air flowing through the duct toward the pneumatic tire when air pressure in the pneumatic tire is reduced.
A vehicle having pneumatic tires, wherein
- at least a portion of an outside surface of each pneumatic tire sidewall is made of a thermal conductive rubber having a thermal conductivity of 0.40 W/(m·K) or more,
- the vehicle includes a cooling device which blows gas from an outside source to cool each pneumatic tire sidewall, and
- wherein said cooling device includes
- a duct which is provided at one end with an air induction port which takes in air, and at the other end with an issuing port which blows the air toward a brake device, and
- a changeover tool which blows at least a portion of the air flowing through the duct toward the pneumatic tire when an air pressure in the pneumatic tire is reduced.
