汽车制动系发生了故障,要作出正确的判断,才能迅速、准确地排除。气压脚制动器发生故障多数是制动失效或制动咬合。一、造成制动失效的主要原因1.储气筒没气或气压不足(低于4.5公斤/厘米~2);2.控制阀开度太小,给气不足;3.控制阀、制动缸、管路等漏气;4.气路堵塞;5.制动间隙不适宜,制动接触面积太小;6.摩擦衬带质量不好或有油;7.制动鼓变形,沟槽太深;8.摩擦衬带没铆紧;9.制动凸轮轴和轴套、制动蹄和销轴
Automotive brake system failure, to make the right judgments, in order to quickly and accurately exclude. Pneumatic foot brake failure is the majority of brake failure or brake occlusion. First, the main reason for failure caused by brake 1. The gas cylinder is not gas or air pressure is less than (less than 4.5 kg / cm ~ 2); 2. Control valve opening is too small, insufficient gas; 3. Control valve, brake cylinder , Pipelines and other gas leakage; 4. Gas blocked; 5. Brake gap inappropriate, brake contact area is too small; 6. Friction lining with poor quality or oil; 7. Brake drum deformation, groove too Deep; 8 friction lining no riveting; 9. brake camshaft and sleeve, brake shoe and pin
