Isilungisi seSlack esizenzekelayo

Intshayelelo kwi-Automatic Slack Adjuster (ASA)

I-Automatic Slack Adjuster, efinyezwe njenge-ASA, yindlela ekwaziyo ukulungisa ngokuzenzekelayo i-brake clearance. Idlala indima ebalulekileyo kwiimeko ezahlukeneyo zokusetyenziswa, ngakumbi kwiinkqubo ze-brake zezithuthi ezifana neemoto noololiwe. Ukuvela kwesi sixhobo kujolise ekuqinisekiseni uzinzo kunye nokuthembeka kwenkqubo ye-brake, njengoko ukufaneleka kwe-brake clearance kuchaphazela ngokuthe ngqo ukusebenza kwe-brake kunye nokhuseleko lwesithuthi.

Imizekelo yesicelo

Kwicandelo leemoto, i-ASA isetyenziswa kakhulu kwiinkqubo zeebhuleki zeelori ezinzima, izithuthi zorhwebo, kunye nezinye izithuthi ezinkulu. Ezi zithuthi, ngenxa yobunzima bazo obukhulu kunye nesantya esiphezulu, zinemfuno ephezulu kakhulu kwinkqubo yeebhuleki. I-ASA ingayilungisa ngokuzenzekelayo indawo evulekileyo yeebhuleki ukuqinisekisa amandla okubhuleka azinzileyo nasebenzayo phantsi kweemeko ezahlukeneyo zendlela kunye neemeko zokuqhuba. Kwicandelo lokuthuthwa koololiwe, njengoololiwe, i-ASA ikwasetyenziswa kakhulu kwiinkqubo zeebhuleki zoololiwe ukuqinisekisa ukusebenza ngokukhuselekileyo koololiwe.

Umgaqo Wokusebenza

Umgaqo wokusebenza we-ASA usekelwe ekuchongeni ngokuchanekileyo nasekulungiseni indawo evulekileyo yebhuleki. Indawo evulekileyo yebhuleki ibhekisa kwindawo evulekileyo phakathi kwe-lining ye-brake friction kunye ne-brake drum (okanye i-brake disc). Le ndawo kufuneka igcinwe kumgama ofanelekileyo, njengoko indawo enkulu kakhulu okanye encinci kakhulu iya kubangela ukusebenza okuphantsi kwe-brake. I-ASA isebenzisa uthotho lwezakhiwo zoomatshini ezintsonkothileyo ukuze ibone indawo evulekileyo yebhuleki ngexesha langempela kwaye yenze uhlengahlengiso njengoko kuyimfuneko.

Ngokukodwa, i-ASA idla ngokuba ne-rack kunye ne-pinion (ingalo yokulawula), i-clutch, i-thrust spring, i-worm gear kunye ne-worm, i-housing, kunye nezixhobo. I-rack kunye ne-pinion zisetyenziselwa ukulawula ixabiso le-theoretical brake clearance, ngelixa i-thrust spring kunye ne-clutch indibaniselwano zisetyenziselwa ukuchonga i-elastic clearance kunye ne-excess clearance ngexesha lokubhuleka. I-worm gear kunye ne-worm structure azidlulisi nje kuphela i-braking torque kodwa zikwalungisa i-brake clearance ngexesha lokukhululwa kwe-brake. Xa i-brake clearance inkulu kakhulu, i-ASA izilungisa ngokuzenzekelayo ukuze iyinciphise; xa incinci kakhulu, yenza uhlengahlengiso olufanelekileyo ukuze iphephe ukuguguleka kakhulu okanye ukubanjwa kwe-friction lining.

Amandla okulungisa achanekileyo e-ASA aqinisekisa uzinzo kunye nokuthembeka kwenkqubo yeebhuleki. Ayiphuculi nje kuphela ukusebenza kakuhle kweebhuleki, inciphisa umgama wokuma, kodwa ikwanciphisa ukuguguleka kunye nokusetyenziswa kwamandla kwenkqubo yeebhuleki, yandisa ubomi benkonzo yezithuthi.

Ngamafutshane, njengesixhobo sokulungisa i-brake clearance esiphucukileyo, i-Automatic Slack Adjuster idlala indima ebalulekileyo kwiinkqubo ze-brake zezithuthi ezahlukeneyo. Ngokuchonga ngokuchanekileyo nokulungisa i-brake clearance, iqinisekisa uzinzo kunye nokuthembeka kwenkqubo ye-brake, inika isiqinisekiso esinamandla sokusebenza ngokukhuselekileyo kwezithuthi.

Ukuba unayo nayiphi na imfuneko ye-slack adjuster, nceda uzive ukhululekile ukunxibelelana nathi ukuze u-odole. Singumzi-mveliso wemvelaphi onamava eminyaka engama-20 kwimveliso kunye nokuthumela ngaphandle ixesha elide.
