I-Automatic Slack Adjuster

Isingeniso se-Automatic Slack Adjuster (ASA)

I-Automatic Slack Adjuster, efushanisiwe njenge-ASA, iwumshini okwazi ukuzilungisa ngokuzenzakalelayo ukususwa kwamabhuleki. Idlala indima ebalulekile ezimeni ezahlukahlukene zokusebenza, ikakhulukazi kumasistimu wamabhuleki ezimoto ezinjengezimoto nezitimela. Ukuvela kwalolu cingo kuhlose ukuqinisekisa ukuzinza nokuthembeka kwesistimu yamabhuleki, njengoba ukufaneleka kokugunyazwa kwamabhuleki kuthinta ngqo ukusebenza kwamabhuleki nokuphepha kwemoto.

Izimo zohlelo lokusebenza

Emkhakheni wezimoto, i-ASA isetshenziswa kakhulu ezinhlelweni zamabhuleki wamaloli asindayo, izimoto zezentengiselwano, nezinye izimoto ezinkulu. Lezi zimoto, ngenxa yesisindo sazo esinzima kanye nesivinini esikhulu, zinezidingo eziphezulu kakhulu zesistimu yamabhuleki. I-ASA ingakwazi ukuzilungisa ngokuzenzakalelayo i-brake clearance ukuze kuqinisekiswe amandla okubhuleka azinzile futhi asebenzayo ngaphansi kwezimo ezihlukahlukene zomgwaqo kanye nezimo zokushayela. Emkhakheni wezokuthutha ngezitimela, njengezitimela, i-ASA isetshenziswa kabanzi ezinhlelweni zamabhuleki esitimela ukuze kuqinisekiswe ukusebenza okuphephile kwezitimela.

Isimiso Sokusebenza

Umgomo wokusebenza we-ASA usekelwe ekuhlonzweni okunembayo nasekulungisweni kokuvunyelwa kwamabhuleki. I-brake clearance isho igebe phakathi kwe-brake friction line kanye nesigubhu sebhuleki (noma i-brake disc). Leli gebe kufanele ligcinwe ngaphakathi kwebanga elifanele, njengoba igebe elikhulu kakhulu noma elincane kakhulu lizoholela ekuncipheni kokusebenza kwamabhuleki. I-ASA isebenzisa uchungechunge lwezinhlaka zemishini eziyinkimbinkimbi ukuze ithole ukuvunyelwa kwamabhuleki ngesikhathi sangempela futhi yenze izinguquko njengoba kudingeka.

Ngokukhethekile, i-ASA ngokuvamile iqukethe i-rack ne-pinion (ingalo yokulawula), i-clutch, i-thrust spring, igiya lezikelemu kanye nezikelemu, izindlu, kanye nezinsiza. I-rack kanye nephinikhodi kusetshenziselwa ukulawula inani le-theoretical brake clearance, kuyilapho inhlanganisela ye-thrust spring ne-clutch isetshenziselwa ukuhlonza i-elastic clearance kanye nokukhululeka ngokweqile ngesikhathi sokubhuleka. Igiya lezikelemu kanye nesakhiwo sezikelemu akugcini ngokudlulisa i-torque yebhuleki kuphela kodwa futhi lungisa i-brake clearance ngesikhathi sokukhishwa kwamabhuleki. Uma imvume yebhuleki inkulu kakhulu, i-ASA iyazilungisa ngokuzenzakalelayo ukuze inciphise; uma incane kakhulu, yenza izinguquko ezihambisanayo ukuze igweme ukuguga ngokweqile noma ukubanjwa kolwelwesi olushayisanayo.

Amandla okulungisa anembile e-ASA aqinisekisa ukuzinza nokuthembeka kwesistimu yamabhuleki. Akugcini nje ngokuthuthukisa ukusebenza kahle kwamabhuleki, kunciphisa ibanga lokuma, kodwa futhi kwehlisa ukuguga nokusetshenziswa kwamandla kwesistimu yamabhuleki, kwandise impilo yesevisi yezimoto.

Kafushane, njengethuluzi elithuthukisiwe lokulungiswa kokuvunyelwa kwamabhuleki, i-Automatic Slack Adjuster idlala indima ebalulekile ezinhlelweni zamabhuleki ezimoto ezahlukahlukene. Ngokuhlonza kahle nokulungisa ukuvunyelwa kwamabhuleki, kuqinisekisa ukuzinza nokuthembeka kwesistimu yamabhuleki, inikeze isiqinisekiso esiqinile sokusebenza okuphephile kwezimoto.

Uma unezidingo ze-slack adjuster, sicela ukhululeke ukuxhumana nathi ukuze uthole i-oda. Siyimboni yomthombo eneminyaka engu-20 yesipiliyoni sokukhiqiza kanye nokuthekelisa isikhathi eside
