Ukuqonda indlela enembile yokubala i-heavy bus air brake chamber thrust kubalulekile ukuqinisekisa ukuphepha nokusebenza kahle kwezinhlelo zokubhuleka kwezimoto zezentengiselwano. Lo mhlahlandlela onegunya unikeza incazelo eningiliziwe yezobuchwepheshe yokuthi ungabala kanjani amandla okukhipha bese ukhetha usayizi ofanele wezidingo zokulungiswa kwezimoto ngemuva kwemakethe kanye nokufakwa esikhundleni sazo.
Incazelo ye-Air Brake Chamber Thrust
Ukucindezelwa kwegumbi lamabhuleki amandla omshini akhiqizwa umoya ocindezelwe osebenza ku-diaphragm eguquguqukayo ngaphakathi kwegumbi lamabhuleki. Kuhlelo olujwayelekile lokubhuleka lwe-S-cam, la mandla aqondile adluliselwa nge-pushrod kuya ku-isilungisi se-slack, okuguqula ukunyakaza kube yi-torque ukuze kufakwe izicathulo zamabhuleki esigubhuni. Ubukhulu balokhu kusunduza bunquma amandla okuma aphelele atholakala ebhasini elisindayo.
Ifomula Yezibalo Yokubala Okuqondiwe
Ukubalwa okuyisisekelo kwamandla okukhipha ikamelo lamabhuleki omoya kulandela umthetho ongokoqobo wokucindezela okuphindaphindwe ngendawo (F=P×A). Ngokwejwayelekileigumbi lokubopha, indawo ephumelelayo inqunywa ngobukhulu be-diaphragm, ehlukaniswa ngezinombolo "Zohlobo" ezimele indawo ngamasentimitha-skwele.
Ifomula:
Ukuphoqa (lbs)=Ukucindezela Komoya (psi)×Indawo Ye-Diaphragm Esebenzayo (sq. in.)
Isibonelo, igumbi lohlobo 30 elisebenza ngokucindezela okujwayelekile kwe-100 psi likhiqiza ama-3,000 lbs okusunduza (30 sq. in. × 100 psi). Ngokusho kwe-I-Commercial Vehicle Safety Alliance (i-CVSA), ukugcina ukushaywa yi-pushrod efanele kanye nokucindezela kubalulekile, njengoba noma yikuphi ukuphambuka kungaholela ekwephulweni "kokungasebenzi" ngesikhathi sokuhlolwa.
Ishadi Lokulinganisa Ikamelo Lebhuleki Lomoya Elinzima Lebhasi Elinzima
Ukukhetha usayizi ofanele kudinga ukufanisa indawo esebenza kahle yegumbi nemininingwane yomkhiqizi wemishini yokuqala yemoto (i-OEM) ukuze kulondolozwe ukubhuleka okulinganiselwe. Amabhasi amaningi asindayo asebenzisa amakamelo ohlobo 24, ohlobo 30, noma ohlobo 36 kuye ngesilinganiso sesisindo se-axle.
| Uhlobo Lwegumbi | Indawo Esebenzayo (isikwele ngaphakathi) | Isisindo esingu-100 PSI (lbs) | Isicelo Esijwayelekile |
|---|---|---|---|
| Uhlobo 16 | 16 | 1,600 | Ama-Axle Okuqondisa Angaphambili (Alula) |
| Uhlobo 20 | 20 | 2,000 | Ama-Axle Okuqondisa Angaphambili (Okujwayelekile) |
| Uhlobo 24 | 24 | 2,400 | Ama-Axle Okushayela Angemuva (Umsebenzi Ophakathi) |
| Uhlobo 30 | 30 | 3,000 | Ama-Axle Okushayela Angemuva (Ibhasi Elinzima) |
| Uhlobo 36 | 36 | 3,600 | Izicelo Ezikhethekile Ezinzima |
Izici Ezithinta Umphumela Wokuthungelana Kwezwe Langempela
Ukulahlekelwa kokusebenza kahle kwemishini kanye nokumelana nentwasahlobo kumele kubalwe lapho kubalwa amandla aphelele alethwa ku-i-caliper yamabhulekinoma izingxenye ze-S-cam. Nakuba ifomula yethiyori inikeza isisekelo, iziphethu zokubuya zangaphakathi zivame ukudla cishe amakhilogremu angu-50 kuya kwangu-100 okusunduza kokuqala. Ngaphezu kwalokho, njengoba ukushaywa kwe-pushrod kukhula, i-engeli ephumelelayo ye-slack adjuster iyashintsha, okungenzeka inciphise i-torque esetshenziswa ku-brake camshaft.
Ukuqhathanisa Amakamelo E-Diaphragm Angawodwa Namabili
Amakamelo okusebenzela (i-diaphragm eyodwa) anikeza amandla okubhuleka kuphela ngesikhathi sokusetshenziswa kwephedali esebenzayo, kanti amakamelo okubhuleka entwasahlobo (i-diaphragm ephindwe kabili) afaka isiphethu esinamandla esiphuthumayo/sokupaka. Ekusethweni kwe-diaphragm ephindwe kabili, "i-Power Spring" inikeza ukuphepha komshini; uma umfutho womoya wehla ngaphansi kwama-psi angu-60, isiphethu siyakhula ukuze sisebenzise amabhuleki ngokuzenzakalelayo. Ukuze kushintshwe, kuqinisekiswa ukuthiivalvu ye-solenoidUkuphatha kahle umoya ophumayo kula makamelo kubalulekile ekukhululweni kwamabhuleki okupaka.
Ukuqonda Imikhawulo Yesifo Sohlangothi kanye Nemingcele Yokuphepha
Usayizi ngamunye wegumbi lamabhuleki une-"stroke ekalwe" ethile kanye "nomkhawulo wokulungiswa kabusha" okungafanele udlulwe ukuqinisekisa ukusunduza okuphezulu. Uma i-pushrod ihamba kakhulu (eyaziwa ngokuthi "ukuphuma ngaphansi"), i-diaphragm ingase ilahlekelwe amandla ayo asebenzayo, okubangela ukwehla okukhulu kwamandla okubhuleka. Imininingwane yemboni evela ku-"Industry" evela ku-"Re-adjustment Limit"Izinhlelo Zezimoto Zezentengiselwano zeBendixkusikisela ukuthi cishe ama-25% okwehluleka kokuhlolwa komgwaqo kuhlobene nokulungiswa okungafanele kwamabhuleki noma ukushaywa ngokweqile.
| Uhlobo Lwegumbi | Umkhawulo Ojwayelekile Wokushaywa Yisifo Sohlangothi | Umkhawulo Wesishayo Esinde |
|---|---|---|
| Uhlobo 20 | Amasentimitha angu-1.75 | Amasentimitha angu-2.0 |
| Uhlobo 24 | Amasentimitha angu-1.75 | Amasentimitha angu-2.0 |
| Uhlobo 30 | Amasentimitha angu-2.0 | Amasentimitha angu-2.5 |
Umhlahlandlela Wokukhetha Ukushintsha Amabhuleki Ebhasi
Uma uthenga izingxenye ku-uhlelo lwamabhuleki eloliumhlinzeki, qinisekisa njalo isikhala sebhawodi lokufaka kanye nobude be-pushrod ngaphezu kohlobo lwegumbi. Amabhasi amakhulu avame ukudinga izinguqulo ze-“Long Stroke” zegumbi lohlobo 30 ukuze anikeze umkhawulo wokuphepha ophezulu ngokumelene nokufiphala kwamabhuleki. Ukusebenzisa igumbi lokushaya elijwayelekile lapho kudingeka khona ukushaywa okude kungaholela ekulahlekelweni kwamabhuleki ngaphambi kwesikhathi ngesikhathi sokwehla kwezintaba noma izimo zokushisa okuphezulu.
Umthelela Wokucindezela Komoya Ebangeni Lokubhuleka
Ukuphinda kabili umfutho womoya kuphinda kabili umfutho, kodwa uhlelo kumele lulinganiswe ukuze luphathe imithwalo enjalo ngaphandle kokwehluleka kwengxenye. Iningi lezinhlelo zomoya ezisindayo zisebenza phakathi kwe-100 ne-125 psi; nokho, ngesikhathi sokubhuleka okuphuthumayo,iphedi yamabhulekiingcindezi ilingana ngqo nomfutho wegumbi okhiqizwa ngaleso sikhathi. Izindinganiso Zokuphepha Zezimoto Zikahulumeni (Federal Motor Vehicle Safety Standards)I-FMVSS 121) nquma amabanga okuma amancane okumele lawa manani okusunduza afinyelele ezisindweni ezahlukene zemoto.
Izinqubo Zokulungisa Ukuze Kusetshenziswe Kahle Kakhulu
Ukuhlola njalo imigqa yezindiza kanyeisilinda esikhulu se-clutch(kuma-transmission asetshenziswa ngesandla) kuqinisekisa ukuthi lonke uhlelo lomoya lugcina ubuqotho obudingekayo ukuze kuthunyelwe ngokugcwele. Ochwepheshe kufanele basebenzise indlela ebaliwe ukuqinisekisa ukuthi izinhlangothi zombili ze-axle zithola ingcindezi elinganayo, njengoba ukungalingani kokucindezelwa okungu-10% kungabangela ibhasi ukuthi lidonse ohlangothini olulodwa ngesikhathi sokubhuleka okukhulu, okubeka engcupheni ukuphepha kwabagibeli.
Isifinyezo Sobuchwepheshe Sezidingo Zosayizi
Ngamafuphi, ukulinganisa igumbi lamabhuleki omoya lebhasi elisindayo kudinga ukuhlonza Uhlobo (Indawo), ukuqinisekisa i-Stroke (Standard vs. Long), nokuqinisekisa ukuthi ihadiwe yokufaka ihambisana ne-axle bracket. Ukubala okufanele kuqinisekisa ukuthi inzuzo yomshini enikezwa yi-slack adjuster ikhuliswa kakhulu, okugcina imoto ingaphakathi kwemingcele yokuphepha esemthethweni.
Imibuzo Evame Ukubuzwa
Ngingawubona kanjani usayizi wegumbi lami lamabhuleki ebhasi uma ithegi ingekho?
Ungabona usayizi ngokulinganisa ububanzi bangaphandle bekamelo ebhendini ye-clamp ephakathi. Isibonelo, igumbi lohlobo lwe-30 livame ukuba nobubanzi bangaphandle obungaba amasentimitha angu-8. Uma sibhekisela eshadini losayizi elisemthethweni elivela ku-UMkhandlu Wezobuchwepheshe Nokunakekelwa (i-TMC)kungasiza ekuqinisekiseni lezi zilinganiso.
Ngingakwazi yini ukufaka esikhundleni segumbi lohlobo 24 ngegumbi lohlobo 30 ukuze ngithole amandla engeziwe?
Ukwandisa usayizi wegumbi ngaphandle kwemvume yobunjiniyela kuyingozi njengoba kudala ukungalingani kwamabhuleki. Igumbi elikhulu ku-axle eyodwa lizobangela ukuthi lawo masondo avale ngokushesha kunamanye, okungase kuholele ekusheleleni noma ekujikeni. Hlala unamathela kuhlobo oluchazwe yi-OEM lwemodeli yakho yebhasi ethile.
Uyini umehluko phakathi "kwendawo ephumelelayo" kanye "nendawo eqondile"?
Indawo eqondile iyisigaba esiyindilinga (njengohlobo 30), kanti indawo ephumelelayo iyi-intshi zesikwele zangempela umoya osebenza kuzo ngesikhathi sokushaya. Nakuba zivame ukuphathwa ngendlela efanayo ekubalweni, ukuguguleka kwe-diaphragm kunganciphisa kancane indawo ephumelelayo eminyakeni eminingana yokusebenza ezindaweni ezinzima.
Izinga lokushisa lithinta kanjani ukucindezelwa kwegumbi lamabhuleki omoya?
Ukubanda okukhulu kungaqinisa i-diaphragm yerabha, kukhulise kancane ingcindezi edingekayo ukuze kunqotshwe ukumelana kokuqala. Ngokuphambene nalokho, ukushisa okuphezulu okuvela kuma-drum kungabangela "ukufiphala kwamabhuleki," lapho izingxenye zomshini zanda khona, okudinga ukushaywa isikhathi eside ukuze kufezwe ukushukuma okufanayo. Yingakho amakamelo okushaywa isikhathi eside ethandwa kakhulu emabhasini asindayo.
Kungani i-engeli ye-pushrod ibalulekile ekubalweni kwe-thrust?
Ukubalwa kokusunduza kukutshela amandla aqondile, kodwa "amandla asebenzayo" ancike ekutheni i-pushrod ibe se-engeli engama-degree angu-90 kuya ku-slack adjuster endaweni yokusetshenziswa kwebhuleki. Uma i-engeli ingaphezulu noma ingaphansi kwama-degree angu-90, ingxenye yokusunduza iyachithwa, okunciphisa i-torque yangempela yokusunduza.
