The slack adjuster, haholo-holo ea "Automatic slack adjuster" (ASA), ke karolo ea bohlokoa ea tšireletso tsamaisong ea drum brake ea likoloi tsa khoebo (joaloka literaka, libese le litereilara). Mosebetsi oa eona o rarahane ho feta oa molamu o bonolo o kopanyang.
1. Hantle-ntle ke Eng?
Ka mantsoe a bonolo, "smart adjuster" ke "borokho" le "smart regulator" lipakeng tsabrake chamber(eo hangata e tsejoang ka hore ke “air can” kapa “brake pot”) leS-camshaft(kapa brake camshaft).
Mosebetsi oa Borokho:** Ha u hatella brake pedal, chamber ea brake e sutumelletsa ka ntle ho pushrod. Pushrod ena e sebetsa ho "slack adjuster", eo le eona e potolohang S-camshaft. Ka mor'a moo camshaft e ala lieta tsa brake ka thōko, e qobella li-linings khahlanong le moropa oa brake ho etsa hore ho be le likhohlano le matla a ho emisa.
Mosebetsi oa Regulator:Ena ke karolo ea eona ea bohlokoa ho feta. E lefa ka bo eona bakeng sa tumello e eketsehileng e bakoang ke ho roala ha mariki, ho etsa bonnete ba hore stroke ea pushrod (hangata e bitsoang "brake stroke" kapa "maeto a mahala") e lula e le ka har'a sebaka se nepahetseng nako le nako ha ho kengoa mariki.
2. Ke Hobane'ng ha e Sebelisoa? (Manual vs. Automatic)
Pele li-automatic slack adjusters li fetoha maemo, likoloi li ne li sebelisoamonyebe oa matsohobahlahlobi.
- Litšitiso tsa Manual Slack Adjusters:
1. Ho itšetleha ka Bokhoni: Ho hlokahala hore mochini o fetolang screw ea tokiso ho ipapisitsoe le boiphihlelo le maikutlo, ho etsa hore ho be thata ho netefatsa ho nepahala.
2. Phetoho e sa Lekaneng:Habonolo e lebisitse ho thibang mariki ho sa tsitsang pakeng tsa mabili a leqeleng le a ka ho le letona a koloi, e bakang ho hula mariki (koloi e khelohela ka lehlakoreng le leng nakong ea braking) le mabili a sa leka-lekaneng (lithaere tse "scalloped").
3. Likotsi Tsa Tšireletseho:Tlhaloso e feteletseng e bakile tieho ea braking le sebaka se selelele sa ho emisa. Ho se be teng ho lekaneng ho ka lebisa ho hula mariki, ho chesa ho feta tekano, le ho hloleha ho sebetsa pele ho nako.
4. Ho ja Nako le Mosebetsi o Batla: Ho hlokeha ho hlahlojoa le ho lokisoa khafetsa, ho eketsa litšenyehelo tsa tlhokomelo le ho theoha ha koloi.
- Melemo ea li-Adjuster tsa Automatic Slack:
1. E boloka Tlokotsi e Ntle ka ho Fetisisa: Ha ho na ho kenella ka letsoho ho hlokahalang; e lula e boloka brake clearance ka boleng bo hlophisitsoeng hantle.
2. Polokeho le Botšepehi:E netefatsa ho arabela ka potlako le ka matla a mariki, e khutsufatsa sebaka sa ho ema, 'me e matlafatsa polokeho ka kakaretso.
3. Moruo le Sebetsa:Ho sebetsa ka mokhoa o leka-lekaneng ho etsa hore lithaere li se ke tsa senyeha le ho feta li-brake linings, ho lelefatsa bophelo ba tsona ba tšebeletso le ho fokotsa litšenyehelo tsa ho sebetsa.
4. Tlhokomelo e tlase le boiketlo:Ha e le hantle, ha e na tlhokomelo, e fokotsa nako ea koloi le litšenyehelo tsa basebetsi.
3. E sebetsa Joang? (Molao-motheo oa mantlha)
Ka hare ho eona ho na le bohlalemokhoa o le mong oa clutch(hangata ke kopano ea seboko le lisebelisoa).
1. Tlhokomelo ea ho Utloa 
ho lla e mong le e mongbrake releasecycle, mochine o ka hare oa ASA o utloa sebaka sa leeto la ho khutla la pushrod.
2. Baahloli ba Ahlolang:Haeba li-brake linings li koaletsoe, tumello e kholoanyane, 'me leeto la ho khutla la pushrod le tla feta boleng bo tloaelehileng bo behiloeng esale pele.
3. Phethahatso ea phetoho:Hang ha leeto le feteletseng la ho khutla le fumanoa, clutch ea tsela e le 'ngoe e sebetsa. Ketso ena e fetola lisebelisoa tsa liboko ka tekanyo e nyane, ka mokhoa o hlakileng "ho nka monyebe" le ho ntshetsa pele moo camshaft e qalang teng ka khutlo e nyane.
4. Mokhoa o le mong:Phetoho enae etsahala feela nakong ea ho lokolloa ha mariki. Ha li-brake li kenngoa, clutch ea theoha, e thibela mochine oa ho lokisa hore o senyehe ke matla a maholo a ho qhoqhoa.
Ts'ebetso ena e pheta-pheta, ho fihlela matšeliso a "incremental, reverse, automatic" le ho netefatsa ts'ebetso e tsitsitseng ea braking.
4. Lintlha Tse ka Sehloohong le Mekhoa e Molemohali
1. Kemiso e Nepahetseng le ho Qala:
- Ena ke mohato oa bohlokoahali! Kamora ho kenya sesebelisoa se secha sa "automatic slack adjuster", utlamehaka letsoho e behe ho "boemo bo tloaelehileng ba pele." Mokhoa o tloaelehileng ke: retelletsa screw ea ho lokisa ho fihlela e emisa (ho bontša hore lieta li hokahane le moropa ka botlalo), ebe ** e khutlisa palo e itseng ea ho chencha kapa ho tobetsa ** (mohlala, "khutlela ho 24 ho tobetsa"). Chelete e sa nepahalang ea ho khutlisa chelete e ka etsa hore brake e hulehe kapa e etse hore tokiso ea othomathike e hloke thuso.
2. Tlhahlobo ea Kamehla:
- Leha e bitsoa "automatic," ha e hloke tlhokomelo ka botlalo. Pushrod stroke e lokela ho lekanyetsoa khafetsa ka rula ho netefatsa hore e lula sebakeng se boletsoeng ke moetsi. Keketseho ea tšohanyetso ea bolelele ba stroke e bontša hore ASA ka boeona e ka ba le phoso kapa ho na le bothata bo bong ba tsamaiso ea mariki (mohlala, camshaft e nkiloeng).
3. Fetola ka Lipara:
- Ho etsa bonnete ba ho leka-lekana braking matla ka mose ho axle, e haholo kgothaletswa hofetola li-axle tsa slack lintlheng tse peli tsa axle e le 'ngoe ka lipara, ho sebelisa mofuta o tšoanang oa lihlahisoa le lihlahisoa tsa mohlala.
4. Boleng ke Bohlokoa:
- Li-adjuster tsa boleng bo tlase li ka sebelisa lisebelisoa tse futsanehileng, tsa ba le kalafo e tlase ea mocheso kapa mokhoa o tlase oa ho sebetsa hantle. Mechini ea tsona ea ka hare ea clutch e ka thella, ea khathala, kapa ea robeha ka tlas'a meroalo e boima le ho qhoma hangata. Sena se lebisa ho tokiso ea "pseudo-automatic" kapa ho hloleha ho felletseng, ho senya polokeho ea koloi hanghang.
Kakaretso
The slack adjuster ke mohlala oa khale oa "karolo e nyane e nang le tšusumetso e kholo." Ka moralo o bohlale oa mochini, e iketsetsa ts'ebetso e hlokang tlhokomelo ea matsoho, e matlafatsang polokeho e sebetsang le moruo oa likoloi tsa khoebo. Bakeng sa beng le bakhanni, ho utloisisa bohlokoa ba eona le ho etsa bonnete ba tšebeliso le tlhokomelo e nepahetseng ke ntlha ea bohlokoa ea ho netefatsa polokeho ea litsela.
