Isilungisi se-Slack esizenzakalelayo

Isingeniso ku-Automatic Slack Adjuster (ASA)

I-Automatic Slack Adjuster, efushaniswe ngokuthi i-ASA, iyindlela ekwazi ukulungisa ngokuzenzakalelayo ukuhlanzwa kwamabhuleki. Idlala indima ebalulekile ezimweni ezahlukene zokusetshenziswa, ikakhulukazi ezinhlelweni zamabhuleki zezimoto ezifana nezimoto nezitimela. Ukuvela kwale divayisi kuhlose ukuqinisekisa ukuzinza nokuthembeka kohlelo lwamabhuleki, njengoba ukufaneleka kokuhlanzwa kwamabhuleki kuthinta ngqo ukusebenza kwamabhuleki nokuphepha kwemoto.

Izimo Zohlelo Lokusebenza

Emkhakheni wezimoto, i-ASA isetshenziswa kabanzi ezinhlelweni zamabhuleki zamaloli asindayo, izimoto zebhizinisi, nezinye izimoto ezinkulu. Lezi zimoto, ngenxa yesisindo sazo esindayo kanye nesivinini esikhulu, zinezidingo eziphakeme kakhulu zesistimu yamabhuleki. I-ASA ingakwazi ukulungisa ngokuzenzakalelayo ukuvunyelwa kwamabhuleki ukuqinisekisa amandla okubhuleka azinzile futhi asebenzayo ngaphansi kwezimo ezahlukene zomgwaqo kanye nezimo zokushayela. Emkhakheni wezokuthutha ngesitimela, njengezitimela, i-ASA isetshenziswa kabanzi ezinhlelweni zamabhuleki esitimela ukuqinisekisa ukusebenza okuphephile kwezitimela.

Isimiso Sokusebenza

Isimiso sokusebenza se-ASA sisekelwe ekuhlonzeni okunembile nasekulungiseni ukuvuleka kwebhuleki. Ukuvuleka kwebhuleki kubhekisela esikhaleni esiphakathi kolwelwesi lokungqubuzana kwebhuleki kanye nesigubhu sebhuleki (noma idiski yebhuleki). Lesi sikhewu kumele sigcinwe ngaphakathi kwebanga elifanele, njengoba igebe elikhulu kakhulu noma elincane kakhulu lizoholela ekunciphiseni ukusebenza kahle kokubhuleka. I-ASA isebenzisa uchungechunge lwezakhiwo zemishini eziyinkimbinkimbi ukuthola ukuvuleka kwebhuleki ngesikhathi sangempela futhi yenze izinguquko njengoba kudingeka.

Ngokukhethekile, i-ASA ngokuvamile iqukethe i-rack kanye ne-pinion (ingalo yokulawula), i-clutch, i-thrust spring, i-worm gear kanye ne-worm, i-housing, kanye nezesekeli. I-rack kanye ne-pinion zisetshenziselwa ukulawula inani le-theoretical brake clearance, kuyilapho i-thrust spring kanye ne-clutch kuhlanganiswa ukuhlonza i-elastic clearance kanye ne-excess clearance ngesikhathi sokubhuleka. I-worm gear kanye ne-worm structure azidlulisi nje kuphela i-braking torque kodwa futhi zilungisa i-brake clearance ngesikhathi sokukhululwa kwebhuleki. Uma i-brake clearance inkulu kakhulu, i-ASA iyazilungisa ngokuzenzakalelayo ukuze iyinciphise; uma incane kakhulu, yenza izinguquko ezifanayo ukuze igweme ukuguguleka ngokweqile noma ukubamba i-friction lining.

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

Ngamafuphi, njengedivayisi yokulungisa ukuhlanzwa kwamabhuleki ethuthukisiwe, i-Automatic Slack Adjuster idlala indima ebalulekile ezinhlelweni zamabhuleki zezimoto ezahlukene. Ngokubona nokulungisa ukuhlanzwa kwamabhuleki ngokunembile, iqinisekisa ukuzinza nokuthembeka kohlelo lwamabhuleki, inikeze isiqinisekiso esinamandla sokusebenza okuphephile kwezimoto.

Uma unezidingo ze-slack adjuster, sicela ukhululeke ukuxhumana nathi ukuze u-ode. Singumthombo wefektri onolwazi lweminyaka engama-20 lokukhiqiza kanye nokuthumela ngaphandle isikhathi eside
