随着全球经济的发展,汽车保有量日益增多,但这也导致能源消耗和尾气排放量逐渐上升。由于社会进步和油价不断上涨,人们对节约石油资源和环保日益重视。轮胎滚动阻力耗油占汽车燃油消耗的14%~17%,轮胎滚动阻力每降低10%,通常可使燃料消耗降低1%~2%。因此,低滚动阻力轮胎的研究和开发成为人们关注的热点。子午线轮胎滚动阻力在各部位的分布是:胎面 With the development of the global economy, car ownership is increasing, but it also leads to gradual increase in energy consumption and exhaust emissions. Due to social progress and rising oil prices, people pay increasing attention to saving oil resources and protecting the environment. Tire rolling resistance fuel consumption accounts for 14% to 17% of automotive fuel consumption, tire rolling resistance is reduced by 10%, usually can reduce fuel consumption by 1% to 2%. Therefore, research and development of low rolling resistance tires become hot spots of concern. Radial tire rolling resistance in various parts of the distribution is: tread
