行驶安全和车速的关系,在相当大的程度上取决于路面的状况,而路面状况又与气候条件相关。 汽车轮胎和道路的附着系数,是决定道路行驶安全程度和评价路面滑溜性的主要指标之一。这个系数在较大的范围内起变化。在清洁而干燥的路面上,附着系数具有最大值(0.7～0.8);在雪或冰覆盖?
The relationship between driving safety and vehicle speed depends to a great extent on the condition of the pavement, which in turn is related to climatic conditions. The adhesion coefficient between the car tires and the road is one of the main indexes that determine the driving safety of the road and evaluate the slipperiness of the road. This coefficient varies over a large range. On clean and dry roads, the adhesion coefficient has a maximum value (0.7 ~ 0.8); covered in snow or ice?
