轮胎作为汽车的关键承载部件之一,具有承受车辆负荷、向路面传递驱动力和制动力等作用,对汽车而言,这些功能必不可少。同时,轮胎也能影响汽车的燃油经济性、操纵性和安全性。轮胎的质量、安装及使用情况直接影响车辆的燃油消耗量。阻止车辆行驶的力包括空气阻力、传动系阻力(内摩擦力)和轮胎滚动阻力,这些力都能加大载重车发动机的燃油消耗量。据统计,在无风平坦的路面上行驶,轮胎的滚动阻力占车辆行驶总阻力的60%,毫无疑问,只有
Tires, as one of the key load-bearing components of a car, have the function of bearing the load of the vehicle and transmitting the driving force and braking force to the road surface. These functions are indispensable to a car. The same time, the tire can also affect the car’s fuel economy, maneuverability and safety. Tire quality, installation and use of a direct impact on vehicle fuel consumption. The forces that prevent the vehicle from traveling include air resistance, driveline resistance (internal friction), and tire rolling resistance, all of which increase the fuel consumption of the truck engine. According to statistics, driving on a flat road without wind, the rolling resistance of the tire accounts for 60% of the total resistance of the vehicle, there is no doubt that only
