What is the Road Adhesion Coefficient?
1 Answers
Generally, the adhesion coefficient is highest on dry, well-maintained asphalt or concrete roads, reaching 0.7-0.8. In contrast, the adhesion coefficient is lowest on snow and ice-covered roads, making them the most prone to skidding. Adhesion Coefficient: The adhesion coefficient is the ratio of the adhesive force to the normal (perpendicular to the road surface) pressure of the wheel. In rough calculations, it can be considered as the static friction coefficient between the tire and the road surface. Determined by the road surface and the tire, the higher this coefficient, the greater the available adhesive force, and the less likely the car is to skid. Influencing Factors: The adhesion coefficient refers to the tire's ability to adhere to different road surfaces. The value of the adhesion coefficient mainly depends on factors such as the road material, surface condition, tire structure, tread pattern, material, and the vehicle's speed.
