On the other hand, hold-down springs ensure that the brake shoes remain securely in place during operation. They prevent the shoes from moving excessively, thereby promoting even wear and optimal contact with the brake drum. If these springs fail or weaken, it can lead to a variety of issues, such as decreased braking efficiency, increased stopping distances, and uneven wear on the brake shoes.
Brake drums are typically made from cast iron due to its strength, durability, and thermal conductivity. They are designed to withstand the extreme conditions associated with heavy braking, such as high temperatures and significant wear and tear. Over time, however, brake drums can become warped or worn, leading to reduced braking efficiency.
Калимаи ниҳоӣ ин аст, ки директорияи баланд барои баракдрамҳо хатарли аст. Барои бехатарии ҳамаи ронандаҳо ва пиёдагардон, муҳим аст, ки ронандагоне, ки ин аниматсияҳои муҳимро фаромӯш накунанд, бо ин соҳа шинос шаванд. Бо баланд шудани ҳарорат, системаи тормоз бо шамол ва мувофиқ ҷудо мешавад, ки ба сари троллейбус шуданд.
