TL180型推土机和ZL50C型装载机上都采用气推油式制动系统,这种方式的缺点是,制动分泵(见附图)的活塞与壳体极易出现锈蚀、卡滞等故障。 当制动分泵的活塞与壳体出现锈蚀、卡滞时,通常是将活塞取出,用砂纸除掉锈迹,并清洗、擦干,重新装复后即可恢复机器的制动性能。 但往往在维修时,因找不到恰当的着力点,无法将活塞从分泵壳体内
TL180-type bulldozers and ZL50C-type loaders are used on the oil-push brake system, this approach has the drawback that the brake cylinder (see photo) of the piston and housing prone to corrosion, jamming and other failures. When the brake cylinder piston and the casing appears rust, stuck, usually the piston removed, remove the rust with sandpaper and clean, dry, re-installed after the restoration of the machine’s braking performance. But often in the maintenance, because they can not find the right focus, can not be the piston from the sub-pump housing
