S-2型制动器系国内首次研制成功的新型单缸制动器。它采用不自锁螺旋付间隙调整机构、直撑式加强闸瓦吊杆、压型制动缸。该制动器能连续、自动、快速补偿闸瓦间隙,一次调整量最大可达5mm。经四年多运用考核,证明工作安全可靠、坚固耐用,抗振性能好、故障少、维修工作量小。已于1985年11月通过部级鉴定。鉴定会认为该制动器具有国内先进水平。应在韶山型电力机车上推广使用,并可
S-2-type brake system for the first time in China successfully developed a new single cylinder brakes. It is not self-locking screw to pay the gap adjustment mechanism, straight strut to enhance the brake shoe, brake pressure cylinder. The brake can be continuous, automatic, fast compensation brake shoe clearance, a maximum adjustment of up to 5mm. After more than four years of use of assessment, that work safe and reliable, durable, good vibration performance, less failure, small maintenance workload. In November 1985 passed ministerial appraisal. Identification will think that the brake with the advanced domestic level. Shaoshan electric locomotive should be widely used, and can be
