Iyini i-ET disk offset ngamagama alula (imingcele, ithonya kanye nokubala)
Okuqukethwe
Iningi labanikazi bezimoto licabanga ukushintsha ukubukeka kwemoto yabo. Futhi ngokuvamile baqala ngokulungisa okulula futhi okungabizi kakhulu - esikhundleni samasondo anezigxivizo ngama-cast amahle. Lapho ukhetha i-disc, abashayeli abaningi baqondiswa ukubukeka nobubanzi, kodwa ungacabangi ukuthi kuneminye imingcele ebalulekile, ukuphambuka okungaba nomthelela omubi esimweni sobuchwepheshe bemoto ngisho nokulawulwa. Ipharamitha ebaluleke kangako, kodwa engaziwa kangako i-disc offset - ET.
Yini i-ET kumarimu
ET (OFFSET) - lesi sifinyezo simelela i-disc offset, ekhonjiswe ngamamilimitha.
Uma inani lale pharamitha liba lincane, isondo lesondo lizophumela ngaphandle. Futhi, ngokuphambene nalokho, lapho imingcele yokuhamba iphakama, i-disk "imigodi" ijula ngaphakathi komshini.
Ukuhamba - leli yigebe phakathi kwendiza (okunamathiselwe), lapho i-disc ihlangana khona nobuso behabhu lapho ifakwe kuyo, kanye nendiza emele, ephakathi nendawo ye-disc rim.
Izinhlobo nezici zemishini
Ukuhamba kwerimu kunezinhlobo ezi-3:
- null;
- okuhle;
- negative.
Ikhodi ye-offset (ET) itholakala phezu komugqa, futhi izinombolo eziseduze kwayo zibonisa imingcele yayo.
positive inani le-offset lisho ukuthi i-eksisi ebekwe mpo yerimu iyibanga elithile ukusuka endaweni yokuxhumana nehabhu.
Null ipharamitha ET ibika ukuthi i-eksisi yediski kanye nendiza yayo yokukhwelana kuyafana.
ngesikhathi negative ipharamitha ET ukususwa kwendawo enamathiselwe kwidiski kuhabhu ngale kwe-eksisi ebekwe mpo yediski.
I-offset evame kakhulu ithi positive, kanti i-negative offset iyivelakancane kakhulu.
Ubukhulu be-overhang buyi-nuance ebalulekile ekwakhiweni kwamarimu, ngakho-ke ifomula ekhethekile isetshenziselwa ukubala ukuze kuqedwe iphutha elingenzeka.
Yini ethinta i-wheel offset
Abakhiqizi bama-rim, ngisho nasenqubweni yokuklama, babala ukuthi kungenzeka yini enye indentation ngesikhathi sokufakwa kwe-rim, ngakho-ke, banquma ubukhulu bobukhulu obungenzeka.
Ukufakwa kahle kwamasondo emotweni kudinga ulwazi nokuqonda uhlobo nobukhulu besondo. Kuphela uma yonke imiyalelo yokufaka ilandelwa, kanye nokuqondana kwawo wonke amapharamitha ediski, okuhlanganisa i-offset, eshiwo umenzi wemoto, kuthathwa njengokulungile ukukhweza isondo.
Phakathi kwamanye amapharamitha, inani le-offset lithinta usayizi we-wheelbase futhi, ngenxa yalokho, indawo elinganayo yawo wonke amasondo omshini. I-offset ayithinteki ububanzi bediski, noma ububanzi bayo, noma imingcele yesondo.
Abathengisi abaningi bamasondo abazi noma bafihle umthelela wokuhamba ekusebenzeni, ukuphatha, noma ukuphepha kwemoto.
Ukuhamba okungalungile kungaholela emiphumeleni ehlukahlukene engalungile, ngezinye izikhathi eyingozi kakhulu.
Imiphumela eyinhloko ye-offset yediski ekhethwe ngokungalungile:
- ukunciphisa impilo yesevisi yama-bearings;
- ukwanda kokugqoka kwerabha;
- ukushintsha indawo ye-axle yokuqondisa;
- ukuncipha okuphawulekayo empilweni yesevisi yokuthwala ngaphansi kwezimoto, okuhlanganisa nokumiswa;
- ukuwohloka kokulawulwa kwemoto, ukuzinza kokuqondisa kanye nokwenzeka kokuqondisa kahle, okungaholela emiphumeleni edabukisayo ngendlela yengozi.
Ungabala kanjani imingcele yokuhamba ngokwakho
Ukuze ubale ukuhamba ngokuzimela, kusetshenziswa ifomula elula kakhulu:
ЕТ=(a+b)/2-b=(ab)/2
а - ibanga phakathi kohlangothi lwangaphakathi lwediski kanye nendiza yokuxhumana kwayo nehabhu.
b ububanzi bediski.
Uma ngesizathu esithile kungekho amanani we-ET kudiski, akunzima ukuwabala ngokwakho.
Lokhu kuzodinga umzila wesitimela oyisicaba, umude kancane kunobubanzi bediski kanye ne-tape measure noma irula yokulinganisa. Uma i-disc isemotweni, izodinga ukukhishwa, okudinga ujeke, isikrufu samasondo, nezicathulo ukuvimbela ukuhlehla.
Imiphumela yokulinganisa kufanele yenziwe ngamamilimitha.
Okokuqala, kuyadingeka ukuthi ujike umugqa ngohlangothi lwangaphandle phansi bese unamathisela isitimela emgqeni werimu. Khona-ke kuyadingeka ukukala ibanga ukusuka engxenyeni yokukhwelana yediski kuya emaphethelweni aphansi wesitimela ngesilinganiso se-tape.
Lesi sibalo siyi-indenti yangemuva а. Ukuze kucace ukubala, ake sicabange ukuthi leli nani lingu-114 mm.
Ngemuva kokubala ipharamitha yokuqala, kuyadingeka ukuvula i-disc ubuso phezulu futhi unamathisele isitimela emgqeni. Inqubo yokulinganisa icishe ifane neyangaphambili. Kuvela ipharamitha b. Ukuze kucace izibalo, siyibheka ilingana no-100 mm.
Sibala i-offset yesondo sisebenzisa amapharamitha akaliwe, ngokuya ngefomula:
ЕТ=(а+b)/2-b=(114+100)/2-100=7 мм
Ngokusho kobukhulu, i-overhang ilungile futhi ilingana no-7 mm.
Kungenzeka yini ukubeka ama-disc ane-overhang encane noma ehlukile
Abathengisi bama-rim baqinisekisa ukuthi ukukhishwa kwe-rim akuphazamisi isimo semoto kanye neminye imingcele nganoma iyiphi indlela, kodwa akufanele bathembeke.
Umgomo wabo oyinhloko ukuthengisa amasondo, kanye neqiniso lokuthi kunezinhlaka ezingaphezu kweshumi nambili zokuhamba - zithule ngenxa yezizathu eziningana, kuhlanganise nobunzima obungase bube ekukhetheni impahla ngokuya ngemingcele edingekayo noma ukuntula ulwazi mayelana nemingcele enjalo futhi umthelela wabo emotweni.
Njengobufakazi besidingo sokuhambisana ne-disc offset esethwe yifektri, kungacatshangwa ukuthi kwezinye izinhlobo zezimoto, kodwa ngokulungiselelwa okuhlukene, izingxenye ezihlukahlukene ezisele zikhiqizwa, ikakhulukazi i-chassis yemoto.
Ngisho noma ezokuthutha zihluka kuphela enjini, lokhu sekuvele kubonakala ngesisindo semoto, futhi, ngenxa yalokho, kumingcele eminingi abaklami abayibala kabusha ekucushweni ngakunye. Namuhla, ekukhiqizeni izimoto, bazama ukunciphisa izindleko, ezithinta insiza yezingxenye, nokulungiswa okuzimele kwemoto ngaphandle kokucabangela imingcele ebekwe umenzi ikakhulukazi kuholela endleleni yokulungisa, ngezinye izikhathi kakhulu. maduze.
Kukhona inketho yokufaka idiski nge-offset ehlukile - ukusetshenziswa kwama-spacers akhethekile. Abukeka njengendilinga yensimbi eyisicaba yobukhulu obuhlukahlukene futhi afakwe phakathi kwediski nehabhu. Ngemva kokukhetha ubukhulu obudingekayo be-spacer, awukwazi ukukhathazeka ngokusebenza okungalungile kwe-chassis namanye amayunithi uma kuthengiwe amarimu amasondo ane-offset ngaphandle kwefekthri.
Okuwukuphela kwe-caveat kuleli cala ukuthi kungase kudingeke ubheke izikhala zobukhulu obudingekayo, ngoba akubona bonke abadayisi bediski abanazo.
Uma ushintsha amadiski, kufanele ucabangele ipharamitha yokususa - ET, ekhonjiswe kuyo. Kodwa kulula ukuzikala ngokwakho ngosizo lwemishini elula ukuthi wonke umnikazi wemoto anayo. Ukuze ukhethe futhi ufake izicathulo ezintsha emotweni, kufanele uhambisane nezidingo zomkhiqizi.
I-offset ye-disc ithinta ukusebenza kwezingxenye eziningi ze-chassis, kodwa okubaluleke kakhulu, i-ET ekhethiwe ngokungalungile inciphisa ukulawulwa komshini, yenza kube nzima ukuzinza kokuqondisa futhi kungaholela emiphumeleni emibi.
Uma isiqu sihlukile efektri, lokhu kungalungiswa ngama-spacers amasondo akhethekile.
