Yini ukuhlangana kwe-viscous fan

Ukuhlangana kwe-viscous kwefeni epholile (i-viscous fan coupling) iyithuluzi lokudlulisa i-torque, kuyilapho kungekho ukuxhumana okuqinile phakathi kwezinto zokushayela nezishayelwayo.

Ngenxa yalesi sici:

• i-torque ingadluliselwa ngokushelela nangokulinganayo;
• Ukudluliswa kwe-torque kuyakhethwa.

Ngokuvamile, i-viscous coupling (i-fan coupling) iyisici esithembekile esinempilo ende yesevisi. Kodwa-ke, kwezinye izimo kuyadingeka ukuhlola ukusebenza komsebenzi, kanye nokushintsha noma ukulungisa ukuhlanganisa. Funda okwengeziwe esihlokweni sethu.

I-Viscous coupling: idivayisi kanye nesimiso sokusebenza

I-viscous fan coupling (i-fluid coupling) iyithuluzi elilula futhi ihlanganisa izici ezilandelayo eziyinhloko:

• i-hermetic case;
• amasondo kagesi noma ama-disc ku-casing;
• amasondo agxilile kuma-axles okushayela futhi aqhutshwa;
• i-silicone fluid (expander) igcwalisa isikhala phakathi kwamasondo;

1. 1. Ngokuvamile, izinhlobo ezimbili eziyinhloko zokuhlanganisa i-viscous zingahlukaniswa. Uhlobo lokuqala lunezindlu, ngaphakathi lapho kukhona amasondo e-turbine ane-impeller. Isondo elilodwa lifakwe ku-drive shaft kanti elinye lifakwe ku-drive shaft. Isixhumanisi esixhumayo phakathi kwamasondo e-turbine uketshezi lwe-silicone, okuwuketshezi olusebenzayo. Uma amasondo ejikeleza ngesivinini esihlukile, i-torque idluliselwa esondweni lokushayela, ukujikeleza kwamasondo kuyavumelaniswa.
   2. Uhlobo lwesibili lwe-clutch luhlukile kunelokuqala ngoba esikhundleni samasondo, i-pair of discs flat anezinsika nezimbobo zifakwe lapha. Kulokhu, uhlobo lwesibili oluvame ukusetshenziswa njenge-clutch fan epholile. Ngokujikeleza okuvumelanayo kwama-disc ngaphakathi kwendlu ye-clutch, uketshezi lwe-silicone aluhlanganisi. Kodwa-ke, uma isigqila siqala ukusala ngemuva kwenkosi, ukuxubana kuyaqalwa. Kulokhu, uketshezi lushintsha izakhiwo zalo (lunwebeka) futhi lucindezela amadiski ngokumelene nomunye.
   3. Ngokuqondene noketshezi lapho umzimba wedivayisi ugcwaliswa khona, isimiso sonke sokusebenza kwe-viscous coupling sisekelwe kuso. Ekuphumuleni, uketshezi luba ne-viscous futhi luwuketshezi. Uma uqala ukuyifudumeza noma ukuyinyakazisa, uketshezi luba lukhulu kakhulu futhi lunwebeka ngevolumu, ukuminyana kwalo kuyashintsha, uma ubuyisela uketshezi esimweni sokuphumula kanye / noma ukuyeka ukushisa, kuzophinde kube yi-viscous kanye noketshezi. Izakhiwo ezinjalo zikuvumela ukuthi ucindezele ama-disc ngokumelene nomunye futhi uvimbele ukuhlangana kwe-viscous, "ukuvala" ama-discs.

Lapho kusetshenziswa ama-viscous couplings emotweni

Njengomthetho, ukuhlangana kwe-viscous ezimotweni kusetshenziswe kuphela ezimweni ezimbili:

• qaphela ukupholisa injini (i-fan yokupholisa);
• xhuma idrayivu yamasondo onke (ukudlulisa).

Inketho yokuqala inedivayisi elula. I-clutch ene-fan igxilile entweni, eqhutshwa ngebhande enjinini. Ngesikhathi esifanayo, ukuhlanganisa i-viscous kuleli cala kunokwethenjelwa kakhulu kunabalandeli bakagesi, kodwa akuphumelelanga kakhulu ngokusebenza.

Ngokuqondene nokufakwa kwe-All-wheel drive, iningi lama-crossovers afakwe i-viscous coupling yokufaka okuzenzakalelayo kwawo wonke amasondo. Ngesikhathi esifanayo, lawa ma-clutches manje kancane kancane ashintshwa ngolunye uhlobo ngendlela yama-actuator kagesi.

Isizathu esiyinhloko ukuthi ukuhlangana kwe-viscous akulula kakhulu ukukugcina (empeleni, kuyalahlwa), futhi futhi akudluliseli i-torque ngokuphumelelayo. Isibonelo, idrayivu enamasondo amane icushwa nge-clutch kuphela lapho amasondo angaphambili ezungeza kakhulu, lapho ingekho indlela yokuphoqa i-clutch, njll.

Indlela eyodwa noma enye, ngisho nokucabangela ukushiyeka, ukuhlanganisa i-viscous kulula ekwakhiweni, kushibhile ukukhiqiza, okuqinile futhi okuthembekile. Isilinganiso sempilo yesevisi okungenani iminyaka emi-5, kanti ekusebenzeni kukhona izimoto ezisuka eminyakeni eyi-10 kuye kweyi-15 ezinama-run ukusuka ku-200 kuya ku-300 km ayizinkulungwane, lapho ukuhlangana kwe-viscous kusebenza kahle. Isibonelo, isistimu yokupholisa yamamodeli amadala e-BMW, ​​lapho ifeni yokupholisa inomshini ofanayo.

Ungahlola kanjani ukuhlangana kwe-viscous

Ukuhlola ukuhlangana kwe-viscous kwe-radiator yokupholisa akuyona inqubo enzima. Ukuze uthole ukuxilongwa okusheshayo, hlola ukujikeleza kwefeni kokubili enjinini eshisayo nebandayo.

Uma ugcwalisa kabusha igesi, ifeni eshisayo iphenduka ngokushesha kakhulu. Ngesikhathi esifanayo, lapho injini ibanda, ijubane alinyuki.

Ukuhlolwa okuphelele kwenziwa ngale ndlela elandelayo:

• Uma injini icishiwe, vula ama-fan blade ngesandla. Ngokuvamile, ukumelana okuncane kufanele kuzwakale, kuyilapho ukujikeleza kufanele kungabi ne-inertia;
• Okulandelayo, udinga ukuqala injini, ngemva kwalokho umsindo omncane ovela ku-clutch uzozwakala ngemizuzwana yokuqala. Ngemva kwesikhashana, umsindo uzophela.
• Ngemva kokuba injini ifudumale kancane, zama ukumisa ifeni ngephepha eligoqiwe. Ngokuvamile ifeni iyama futhi kuzwakale amandla. Ungakwazi futhi ukususa i-clutch bese uyishisa ngokuyibeka emanzini abilayo. Ngemuva kokushisa, akufanele ijikeleze futhi imelane ngokujikelezayo. Uma ukuhlangana okushisayo kuzungeza, lokhu kubonisa ukuvuza kwe-silicone-based hydraulic fluid.
• Kulokhu, kuyadingeka ukuhlola imvume ye-longitudinal yedivayisi. Ukuba khona kokuhlehla okunjalo kukhombisa ngokusobala ukuthi ukuhlangana kwe-fan fluid kudinga ukulungiswa noma i-viscous coupling idinga ukushintshwa.

Ukulungiswa kokuhlanganiswa kwe-viscous

Uma kwenzeka ukuthi imoto iqale ukushisa futhi inkinga ihlobene nokuhlanganisa i-viscous, ungazama ukuyilungisa. Okufanayo kusebenza ku-clutch drive. I-clutch ayizange ilungiswe ngokusemthethweni, i-silicone fluid ayishintshiwe, ukuthwala akushintshiwe, njll.

Kodwa-ke, ekusebenzeni, ukufaka uketshezi olunjalo noma ukufaka esikhundleni sokuthwala kungenzeka, okuvame ukuvumela idivayisi ukuthi iphinde isebenze. Okokuqala udinga ukuthenga amafutha e-viscous coupling afanelekile (ungasebenzisa i-original noma i-analogue) noma uhlobo lwe-viscous lokulungisa uketshezi lokulungisa indawo yonke.

Sincoma futhi ukufunda i-athikili yokuthi ungashintsha kanjani uketshezi lokuqondisa amandla. Kulesi sihloko uzofunda ukuthi ungashintsha nini amafutha esiteringini samandla, uhlobo luni lwamafutha okugcwalisa isiteringi samandla, nokuthi ungakwenza kanjani ngokwakho.

Okulandelayo uzodinga:

1. Susa i-clutch emotweni;
2. Yehlisa idivayisi;
3. Beka ukuhlanganisa ngokuvundlile bese ususa iphinikhodi ngaphansi kwepuleti ngentwasahlobo;
4. Thola umgodi wokukhipha uketshezi (uma kungenjalo, zenzele wena);
5. Ukusebenzisa isirinji, uthele cishe u-15 ml wamanzi ku-cuff;
6. I-liquid ithululelwa ezingxenyeni ezincane (i-silicone kufanele isakaze phakathi kwama-discs);
7. Manje i-clutch ingafakwa futhi ifakwe kabusha;

Uma umsindo uzwakala ngesikhathi sokusebenza kwe-viscous coupling, lokhu kubonisa ukwehluleka ukuthwala. Ukufaka esikhundleni se-viscous coupling bear, uketshezi lwe-silicone lukhishwa kuqala (bese luthelwa emuva ngemva kokushintshwa). Khona-ke i-disk engenhla isusiwe, i-bearing isuswa nge-puller, i-flaring ipholishwa ngokuhambisana futhi i-bearing entsha (uhlobo oluvaliwe) ifakiwe.

Kubalulekile ukuqonda ukuthi lapho wenza imisebenzi ehlukahlukene, kufanele uqaphele kakhulu. Isibonelo, ngisho nokuguqulwa okuncane kwe-clutch disc kuzoholela ekuhlulekeni okuphelele kwedivayisi. Futhi, ungavumeli uthuli noma ukungcola kungene ngaphakathi kwedivayisi, ungasusi amafutha akhethekile, njll.

 

Ukukhetha nokushintshwa kokuhlanganisa

Ngokuqondene nokushintshwa, kuyadingeka ukususa idivayisi endala bese ubeka entsha endaweni yayo, bese uhlola ukusebenza. Eqinisweni, ubunzima obuningi buvela hhayi ngokushintshwa ngokwako, kodwa ngokukhethwa kwezingxenye ezisele.

Kubalulekile ukukhetha ikhwalithi enhle yekhwalithi ye-viscous fan coupling noma idrayivu coupling ukuze kushintshwe. Ukuze wenze lokhu, udinga ukuthola ikhodi yengxenye yokuqala eyisipele, ngemuva kwalokho unganquma ama-analogue atholakalayo kumakhathalogi. Uzodinga futhi i-VIN yemoto, ukwakheka, imodeli, unyaka wokukhiqiza, njll. ukuze ukhethe ngokunembile izingxenye. Sincoma futhi ukufunda isihloko sokuthi kungani injini ishisa kakhulu. Kulesi sihloko, uzofunda ngezimbangela eziyinhloko zokushisa kwenjini, kanye nezindlela ezitholakalayo zokuxilonga nokulungisa.

Ngemva kokuthola ukuthi iyiphi ingxenye edingekayo, kufanele unake umenzi. Njengoba kunikezwe iqiniso lokuthi izinkampani ezimbalwa kuphela ezikhiqiza ukuhlangana kwe-viscous, kungcono ukukhetha phakathi kwabakhiqizi abahamba phambili: i-Hella, i-Mobis, i-Beru, i-Meyle, i-Febi. Njengomthetho, laba bakhiqizi abafanayo nabo bakhiqiza ezinye izingxenye (ama-radiators okupholisa, ama-thermostats, amayunithi okumiswa, njll.).
