В данной статье представлены методы определения количества частиц, выбрасываемых в окружающую среду в результате износа тормозных колодок при торможении автомобиля с учётом коэффициента трения колеса с дорогой. Учитывая изменения срока ресурса тормозных колодок автомобиля в зависимости от коэффициента контакта колёс с дорогой, теоретически рассчитано количество частиц, выбрасываемых ими в атмосферу. Также широко освещён анализ распределения концентрации металлов в частицах, образующихся при износе тормозных колодок при торможении автомобилей. Источники, связанные с дорожным движением, вносят значительный вклад в образование твёрдых частиц в воздухе городов. Установлено, что пробы, взятые в процессе торможения автомобиля, содержат большое количество металлических элементов, таких как железо, медь, цинк, хром, олово и сурьма. В настоящее время имеются сведения о негативном влиянии частиц, образующихся при торможении автомобилей, на окружающую среду. В статье представлен сравнительный анализ теоретических и экспериментальных результатов скорости износа тормозных колодок в зависимости от коэффициента хода. По результатам сравнительного анализа результатов теоретического расчёта средней скорости износа тормозных колодок автомобиля в зависимости от коэффициента сцепления с дорогой установлено, что скорость износа изменяется в зависимости от коэффициента сцепления.

This paper presents methods of determining the amount of particles emitted into the environment as a result of brake pad wear during car braking, taking into account the coefficient of friction of the wheel with the road. The amount of particles emitted by brake pads into the atmosphere is theoretically calculated, taking into account the change in the service life of the brake pads of a car depending on the contact coefficient of the wheels with the road. The analysis of metal concentration distribution in particles produced by brake pad wear during car braking is also extensively covered. Road traffic-related sources contribute significantly to the formation of particulate matter in urban air. Samples taken during vehicle braking have been found to contain large amounts of metallic elements such as iron, copper, zinc, chromium, tin, and antimony. At present, there is evidence of the negative impact of particles generated during automobile braking on the environment. The paper presents a comparative analysis of theoretical and experimental results of brake pad wear rate depending on the stroke coefficient. According to the results of the comparative analysis of the results of the theoretical calculation of the average wear rate of car brake pads depending on the coefficient of grip, it is established that the wear rate varies depending on the coefficient of grip.
