Isilungelelanisi se-Slack esizenzekelayo

Intshayelelo ye-Automatic Slack Adjuster (ASA)

I-Automatic Slack Adjuster, efinyeziweyo njenge-ASA, sisixhobo esikwaziyo ukuzilungelelanisa ngokuzenzekelayo ukucocwa kweziqhoboshi. Idlala indima ebalulekileyo kwiimeko ezahlukeneyo zokusebenza, ngakumbi kwiinkqubo zokuqhokra izithuthi ezinjengeemoto kunye noololiwe. Ukuvela kwesi sixhobo kujolise ekuqinisekiseni ukuzinza kunye nokuthembeka kwenkqubo ye-brake, njengoko ukufaneleka kwe-brake clearance kuchaphazela ngokuthe ngqo ukusebenza kwe-braking kunye nokhuseleko lwesithuthi.

Iimeko zeSicelo

Kwintsimi yeemoto, i-ASA isetyenziswa ngokubanzi kwiinkqubo zokuqhawula iilori ezinzima, izithuthi zorhwebo, kunye nezinye izithuthi ezinkulu. Ezi zithuthi, ngenxa yobunzima bazo kunye nesantya esiphezulu, zineemfuno eziphezulu kakhulu zenkqubo yeziqhoboshi. I-ASA inokuhlengahlengisa ngokuzenzekelayo ukukhutshwa kwe-brake ukuqinisekisa ukunyanzeliswa okuzinzileyo kunye nokusebenzayo okusebenzayo phantsi kweemeko ezahlukeneyo zendlela kunye neemeko zokuqhuba. Kwintsimi yezothutho zikaloliwe, ezifana nezitimela, i-ASA isetyenziswa ngokubanzi kwiinkqubo zokubhuleka koololiwe ukuqinisekisa ukusebenza ngokukhuselekileyo koololiwe.

Umgaqo wokuSebenza

Umthetho-siseko wokusebenza we-ASA usekwe kuchongo oluchanekileyo kunye nohlengahlengiso lokususwa kweebhuleki. Ukususwa kwebrake kubhekiselele kumsantsa ophakathi kwentambo yebrake kunye negubu lebrake (okanye idiski yebrake). Lo msantsa kufuneka ugcinwe ngaphakathi kuluhlu olufanelekileyo, njengoko umsantsa omkhulu kakhulu okanye omncinci kakhulu uya kubangela ukucutheka kokusebenza kweziqhoboshi. I-ASA isebenzisa uthotho lwezakhiwo ezintsonkothileyo zoomatshini ukubona ukukhutshwa kwebrake ngexesha lokwenyani kunye nokwenza uhlengahlengiso njengoko kuyimfuneko.

Ngokukodwa, i-ASA ihlala ine-rack kunye ne-pinion (ingalo yokulawula), i-clutch, i-thrust spring, i-worm gear kunye ne-worm, indlu, kunye nezixhobo. I-rack kunye ne-pinion zisetyenziselwa ukulawula ixabiso le-brake clearance ye-theoretical, ngelixa i-thrust spring kunye ne-clutch indibaniselwano isetyenziselwa ukuchonga i-elastic clearance kunye nokukhutshwa ngokugqithiseleyo ngexesha lokuqhawula. Igiya yeentshulube kunye nolwakhiwo lweentshulube aludluliseli nje i-torque ye-braking kodwa luhlengahlengisa ukucocwa kwebhuleki ngexesha lokukhutshwa kwebrake. Xa i-brake clearance inkulu kakhulu, i-ASA ilungisa ngokuzenzekelayo ukuyinciphisa; xa incinci kakhulu, yenza uhlengahlengiso oluhambelanayo ukuphepha ukuguga okugqithisileyo okanye ukubamba umgca wokukhuhlana.

Amandla okulungelelaniswa okuchanekileyo kwe-ASA iqinisekisa ukuzinza kunye nokuthembeka kwenkqubo ye-brake. Ayiphuculi kuphela ukusebenza kakuhle kwe-braking, kunciphisa umgama wokumisa, kodwa kunciphisa ukunxiba kunye nokusetyenziswa kwamandla kwenkqubo ye-brake, ukwandisa ubomi benkonzo yezithuthi.

Isishwankathelo, njengesixhobo esiphucukileyo sohlengahlengiso lwe-brake, i-Automatic Slack Adjuster idlala indima ebalulekileyo kwiinkqubo zokuqhobosha zezithuthi ezahlukeneyo. Ngokuchonga ngokuchanekileyo kunye nokulungelelanisa ukuchithwa kwe-brake, iqinisekisa ukuzinza kunye nokuthembeka kwenkqubo ye-brake, inika isiqinisekiso esinamandla sokusebenza ngokukhuselekileyo kwezithuthi.

Ukuba unazo naziphi na iimfuno zesilungelelanisi se-slack, nceda uzive ukhululekile ukuqhagamshelana nathi ukuze u-odole. Siyimveliso yomthombo oneminyaka engama-20 yamava emveliso kunye nokuthumela ngaphandle kwexesha elide
