Многозвенность прижимающего механизма не только увеличивает прижимное усилие в рабочих парах тормоза, но и становится причиной усиления колебательного процесса в трибоконтакте тормозных устройств. В статье приведены аналитические зависимости для определения угловых перемещений рычага и тормозной колодки прижимающего механизма тормозного устройства. С помощью математического моделирования удалось установить, что с увеличением разницы частот рычага и тормозной колодки прижимающего механизма силового устройства количество и амплитуда отскока тормозной колодки от рабочей поверхности диска возрастают, что приводит к снижению параметров стабильности эксплуатационных характеристик тормоза.</p></abstract><trans-abstract xml:lang="en"><p>Rolling stock braking devices differ from devices used in other types of transport due to the presence of a transmission mechanism in the drive. The multiplicity of the clamping mechanism provides not only an increase in the clamping force in the working pairs of the brake, but also causes an increase in the oscillatory process in the tribocontact of the braking devices. The article presents analytical dependencies for determining the angular movements of the lever and brake pad of the clamping mechanism of the braking device. Using mathematical modeling, it was found that with an increase in the frequency difference between the lever and the brake pad of the clamping mechanism of the power device, the number and amplitude of the rebound of the brake pad from the working surface of the disc increases, which leads to a decrease in the stability parameters of the brake performance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нелинейная динамика</kwd><kwd>колебательный процесс</kwd><kwd>угловые перемещения</kwd><kwd>прижимающий механизм</kwd><kwd>тормозное устройство</kwd><kwd>рычаг</kwd><kwd>тормозная колодка</kwd><kwd>отскок</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nonlinear dynamics</kwd><kwd>oscillatory process</kwd><kwd>angular displacement</kwd><kwd>clamping mechanism</kwd><kwd>braking device</kwd><kwd>lever</kwd><kwd>brake pad</kwd><kwd>rebound</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ковтун, Е.
