东风及东风_(2、3)型机车采用吊挂式单侧单闸瓦基础制动装置。如何根据规程要求进行检修和维护保养,是克服基础制动装置作用不良和保障行车安全的一个重要环节。 (一)关于闸瓦偏磨在检修运用中,闸瓦偏磨是基础制动装置作用不良较常见的现象之一。主要表现为与轮缘贴靠的闸瓦凹槽部分很快被磨损(即当闸瓦厚度还未到更换限度时,凹槽部分已被磨平),使其在制动时起不到限制闸瓦向外窜动的作用,特别是2、5位闸瓦反映比较突出。这个问题的发生,可以从机车原设计和日常的维
Dongfeng and Dongfeng _ (2,3) locomotive with hanging single-brake single-brake foundation brake device. How to carry out overhaul and maintenance according to the rules and regulations is an important part of overcoming the bad function of the basic brake device and ensuring traffic safety. (A) on the brake shoe wear In the overhaul, brake shoe wear is the basis of poor braking device is one of the more common phenomenon. Mainly as the part of the brake shoe that is in abutment with the rim is quickly worn out (ie, the part of the recess has been smoothed out when the thickness of the brake shoe has not yet been changed) so that it is not restricted during braking Brake shoes to move out of the role, especially the 2,5 brake shoe reflect more prominent. This problem can occur from the locomotive original design and daily dimension
