Ukukhetha phakathi kwezilungisi ze-slack ezenziwe ngesandla nezizenzakalelayo kuyisinqumo esibalulekile sabaphathi bokulungiswa kwezimoto kanye nochwepheshe abazimele abagxile ekulungisweni kwesistimu yamabhuleki ezimoto zezentengiselwano. Lo mhlahlandlela ophelele uqhathanisa imininingwane yobuchwepheshe, izidingo zokugcinwa, kanye nemiphumela yokuphepha yazo zombili izingxenye ukuze kukusize unqume ingxenye efanele yokufaka esikhundleni yamaloli athwala kanzima, amabhasi, kanye nama-trailer.
Ukuqonda Indima Yabalungisi Be-Slack ku-Braking Systems
I-slack adjuster iyisixhumanisi somshini phakathi kwe-pushrod yegumbi lamabhuleki kanye ne-camshaft kumabhuleki e-S-cam, eklanyelwe ukukhokhela ukuguguleka kwe-lining yamabhuleki. Ngokugcina isikhala esifanele phakathi kwe-drama yamabhuleki kanye ne-lining, lezi zingxenye ziqinisekisa ukuthi amandla okubhuleka ahlala engaguquguquki kuwo wonke amasondo. Emkhakheni we-aftermarket, ukukhetha ikhwalithi ephezuluizingxenye zesistimu yamabhulekikubalulekile ekubuyiseleni imoto ezindinganisweni zayo zokuphepha zokuqala.
Izilungisi ze-slack ezenziwe ngesandla zidinga uchwepheshe ukuthi aqinise i-adjustment bolt ngokomzimba ukuze athathe "i-slack" eyenziwe njengoba ama-brake pad ewohloka. Ngakolunye uhlangothi, izilungisi ze-slack ezizenzakalelayo (ama-ASA) zinendlela yangaphakathi elungisa i-brake stroke ngokuzenzakalelayo ngesikhathi sokusebenza okuvamile. Ngokusho kwe-I-Commercial Vehicle Safety Alliance (i-CVSA), ukulungiswa okungafanele kwamabhuleki kusalokhu kungenye yezimbangela eziphambili zokwephulwa kwemithetho yokungasebenzi ngesikhathi sokuhlolwa komgwaqo.
Ukuqhathanisa Kobuchwepheshe: Ama-Adjusters e-Manual vs. Automatic Slack
Umehluko omkhulu phakathi kwezilungisi zesandla nezenzakalelayo zisebunkimbinkimbi bazo bokusebenza kanye nendlela yazo yokugcina i-pushrod stroke. Izinguqulo ezenziwe ngesandla zilula, eziqukethe isethi yegiya ehamba kuphela uma ilungiswa nge-wrench. Izinguqulo ezizenzakalelayo zisebenzisa ubuchwepheshe "bokubona i-stroke" noma "bokubona i-clearance" ukuqapha ukunyakaza kwesistimu yamabhuleki nokulungisa i-clearance kancane kancane.

Isikhathi Sokukhetha Izilungisi Ze-Slack Zesandla Zokulungisa
Ama-adjuster e-hand slack avame ukuthandwa ekulungisweni okuthile kwangemva kwemakethe lapho imoto yayifakwe khona ekuqaleni futhi isebenza ezindaweni lapho ukuhlolwa kwe-hand manual kwansuku zonke kungenzeka khona. Ngenxa yokuthi ayinazo izibambo zangaphakathi eziyinkimbinkimbi, ama-adjuster e-hand manual awakwazi ukubanjwa ezindaweni ezinzima nezingcolisayo lapho usawoti womgwaqo uvame khona. Ochwepheshe bavame ukuthola ukuthiisilungisi sokushelela ngesandlainikeza ikhambi eliqinile nelingabizi kakhulu lama-trailer amadala noma imishini ekhethekile engaphandle komgwaqo.
Kodwa-ke, ukusetshenziswa kwezilungisi ezenziwe ngesandla kudinga isimiso sokulungisa esihlelekile.Ukuphathwa Kokuphepha Kwemigwaqo Kazwelonke (i-NHTSA)kugcizelela ukuthi amabhuleki kumele ahlolwe nsuku zonke ukuqinisekisa ukuthi i-pushrod stroke ayidluli umkhawulo osemthethweni. Ukwehluleka ukulungisa lezi zingxenye ngesandla kuholela "ekufeni kwamabhuleki," lapho isigubhu sikhula khona ngenxa yokushisa futhi izicathulo zingakwazi ukufinyelela phezulu, okuholela ekulahlekelweni ngokuphelele kwamandla okubhuleka.
Izinzuzo Zokulungisa I-Automatic Slack ku-Modern Fleets
Ama-automatic slack adjusters ayindinganiso yemboni yezimoto zesimanje zezentengiselwano ngoba anciphisa kakhulu isikhathi somsebenzi esidingekayo ekunakekelweni kwamabhuleki. Ngokugcina njalo indawo evulekile, ama-ASA aqinisekisa ukuthi imoto ihlala ihambisana nemikhawulo ye-brake stroke kahulumeni ngaphandle kokudinga uchwepheshe ukuthi angene ngaphansi kwe-chassis phakathi kwezikhawu zesevisi ezihleliwe.isilungisi sokushelela okuzenzakalelayokungathuthukisa isilinganiso sokuphepha semikhumbi yonke.
I-ASA “ebona ukususwa kwesikhala” isebenza kahle kakhulu ngoba ilinganisa igebe phakathi kolwelwesi kanye nesigubhu, kunokuba ilinganise ukushaya okuphelele kwesigubhu. Lokhu kuvimbela ukulungiswa ngokweqile, okungenzeka uma isigubhu samabhuleki sishisa futhi sinwetshiwe. Iningi lesimanje kakhuluivalvu yokubopha umoyaizinhlelo zisebenza ngokubambisana nama-ASA ukuze kuhlinzekwe ukubhuleka okulinganiselayo kuwo wonke ama-axle, kunciphisa ukuguguleka kwamathayi futhi kwandise impilo yezintambo zamabhuleki.
Izinto Okufanele Uzicabangele Zokunakekela Nokufaka
Ukuthembeka kwanoma yisiphi isilungisi se-slack kuncike ekugcotshweni nasekufakweni okufanele. Ama-ASA, ikakhulukazi, ayazwela uhlobo lwamafutha asetshenziswayo; ukusebenzisa amafutha angalungile kungaholela ekushelelekeni kwe-clutch yangaphakathi. Ezindaweni zokulungisa, ukufaka esikhundleni seyunithi egugile nge-newi-camshaft yamabhulekifuthi ukuhlanganiswa kwe-adjuster kuvame ukusebenza kahle kakhulu kunokuzama ukwakha kabusha ingxenye ebanjiwe.
Ukuqhathaniswa Kwezidingo Zokunakekela
| Umsebenzi | Isilungisi se-Slack esenziwe ngesandla | Isilungisi se-Slack esizenzakalelayo |
|---|---|---|
| Imvamisa Yokugcoba | Njalo ngamamayela ayi-10,000 – 25,000 | Njalo ngamamayela angu-25,000 – 50,000 (noma njalo ngokushintsha uwoyela) |
| Ukuhlolwa | Ukuhlolwa kwesifo sohlangothi kwansuku zonke/ngaphambi kohambo | Umjikelezo ngamunye we-PM (Preventive Maintenance) |
| Ukulungiswa | Kuyadingeka uma i-stroke idlula umkhawulo | Akuvunyelwe ngaphandle kwalapho kufakwa okokuqala |
| Ukwehluleka Okuvamile | Imicu ehlutshiwe/Amabhawodi ayindilinga | I-clutch yangaphakathi ebanjiwe/i-actuator egugile |
Izindinganiso zemboni ezivela ku-Inhlangano Yonjiniyela Bezimoto (i-SAE)basikisela ukuthi ukulungiswa ngesandla kwe-ASA ukuze "kulungiswe" ibhuleki elingalungiseki kuyisinyathelo sesikhashana esivame ukukhombisa ukuthi i-adjuster yehlulekile futhi idinga ukushintshwa.
Ukuhlaziywa Kwezindleko Nezinzuzo Zokulungisa Nokufaka Esikhundleni
Nakuba intengo yokuqala yokuthenga ye-automatic slack adjuster iphakeme kuneyenziwe ngesandla, izindleko eziphelele zobunikazi ngokuvamile ziphansi ezimotweni zezentengiselwano ezihamba ngamamayela amaningi. Ukonga abasebenzi ngokulungiswa ngesandla okuqediwe kunciphisa ngokushesha izindleko zezingxenye eziphezulu.
