1 Ιαν 2023 · The test data available provide proof of tyre failures throughout the 128–152 km/h rated speed (80–95 mph) with 90–95% due to internal amplitude failures throughout the tyre, 2–10% due to friction here among tyre as well as the pavement, and 1.5–3.5% due of air resistance.
1 Ιαν 2014 · A car and a tire require such diverse performances: handling, braking, durability, wear-resistance, NVH performance, fuel-efficiency, and so forth. Among them, a driver's stability is mainly related with the performances of handling and braking.
20 Απρ 2023 · It was found that, with ABS, the coefficient of friction was on average 13% higher on dry surfaces and 30% higher on wet surfaces, resulting in a 14.3% reduction in stopping distance on dry surfaces and a 37% reduction on wet surfaces.
1 Ιουν 2020 · This study investigated the effect of tire characteristics with different-sized tires, including coefficients of cornering, camber stiffness, and peak lateral friction. Accordingly, rollover resistance and lateral stability were examined under conditions of normal and extreme maneuvering conditions [14] .
1 Μαρ 2012 · Potential actions to reduce friction in passenger cars include the use of advanced coatings and surface texturing technology on engine and transmission components, new low-viscosity and low-shear lubricants and additives, and tire designs that reduce rolling friction. Highlights.
The friction between the tires of your automobile and the road determine your maximum acceleration, and more importantly your minimum stopping distance. So the nature of that friction could actually be a matter of life and death. But like all applications of friction, it has frustrating ambiguities.
A recent comprehensive study by Holmberg et al. estimated that nearly one-third of the total fuel (amounting to 2 × 10 11 l) used by cars is spent to overcome friction and other mechanical and hydrodynamic losses in engines, transmissions, tires, and brakes.
