Chifukwa chake, kukonza kapangidwe ka sealing kuti muchepetse strike torque kumatha kukulitsa kwambiri magwiridwe antchito a ma hub bearing. Ma Hub bearing asintha kuchokera ku m'badwo woyamba kupita ku m'badwo wachinayi waposachedwa, ndipo strike torque imachepa kwambiri komanso pang'onopang'ono.
Ukadaulo wa ABS
ABS ndi chipangizo chowongolera chitetezo cha magalimoto chomwe chili ndi zabwino monga anti-slip ndi anti-lock. Galimoto ikagunda mwadzidzidzi, imasintha yokha mphamvu ya braking pozindikira liwiro la gudumu kuti mawilo asatsekeke ndikufupikitsa mtunda wa braking. Kuzindikira liwiro lozungulira kumachitika ndi masensa a maginito omwe amaikidwa pazigawo zomwe zimazungulira ndi mawilo ndi pafupi zomwe zimakhazikika pa thupi la galimoto. Pali mitundu iwiri ya ma hub units okhala ndi masensa a ABS: imodzi imayikidwa mkati mwa hub, pomwe masensa amayikidwa pazigawo zina; Mtundu wina umayikidwa mkati mwa hub pamodzi ndi sensa (yotchedwa hub unit yokhala ndi sensa).
Ma hub bearing kapena ma hub unit osweka kapena owonongeka angayambitse kulephera kosayenera komanso kokwera mtengo kwa galimoto yanu poyendetsa, komanso kuopseza chitetezo chanu. Chonde samalani ndi zinthu zotsatirazi mukamagwiritsa ntchito ndikuyika ma hub bearing:
Kuti muwonetsetse kuti galimotoyo ndi yotetezeka komanso yodalirika kwambiri, tikukulimbikitsani kuti muziyang'ana ma hub bearing nthawi zambiri mosasamala kanthu za msinkhu wa galimotoyo - samalani ndi zizindikiro zoyambirira za kuwonongeka kwa ma bearing: kuphatikizapo phokoso lililonse la kukangana mukazungulira kapena kuchepa kwa liwiro la mawilo osakanikirana a suspension mukazungulira.
Pa magalimoto oyendetsa mawilo akumbuyo, akulangizidwa kuti ma bearing akutsogolo azipaka mafuta galimoto ikayenda makilomita 38,000. Mukasintha makina oletsa mabuleki, yang'anani ma bearing ndikusintha zomatira zamafuta.
Ngati mumva phokoso losazolowereka kuchokera ku malo operekera mpweya, chinthu choyamba komanso chofunikira kwambiri ndikupeza komwe phokosolo limachitika. Pali zinthu zambiri zosuntha zomwe zingayambitse phokoso, kapena zitha kukhala kuti zinthu zina zozungulira zakhudzana ndi zinthu zosazungulira. Ngati zatsimikiziridwa kuti phokosolo ndi lochokera ku pereka mpweya, pereka mpweyawo ukhoza kuwonongeka ndipo uyenera kusinthidwa.
Popeza mikhalidwe yogwirira ntchito yomwe imayambitsa kulephera kwa ma bearing mbali zonse ziwiri chifukwa cha malo ogwirira mawilo akutsogolo ndi yofanana, tikukulimbikitsani kuti muwasinthe awiriawiri ngakhale bearing imodzi yokha yawonongeka.
Ma Hub bearing ndi osavuta kugwiritsa ntchito, ndipo mulimonsemo, njira zoyenera ndi zida zoyenera ziyenera kugwiritsidwa ntchito. Pakusunga, kunyamula ndi kukhazikitsa, zigawo za bearing siziyenera kuwonongeka. Ma bearing ena amafunika kupanikizika kwakukulu kuti akanikizidwe, kotero zida zapadera zimafunika. Onetsetsani kuti mwawerenga buku lothandizira kupanga magalimoto.
Mukayika ma bearing, ayenera kuchitidwa pamalo oyera komanso aukhondo. Tinthu tating'onoting'ono tomwe timalowa m'ma bearing tidzafupikitsanso nthawi yawo yogwira ntchito. Ndikofunikira kwambiri kusunga malo oyera posintha ma bearing. Sikuloledwa kugunda bearing ndi nyundo. Samalani kuti musagwetse bearing pansi (kapena kuigwira molakwika mwanjira yofanana). Musanayike, mkhalidwe wa shaft ndi bearing housing ziyeneranso kuyang'aniridwa. Ngakhale kuwonongeka pang'ono kungayambitse kusakwanira bwino, zomwe zimapangitsa kuti bearing iwonongeke msanga.
Pa ma hub bearing units, musayese kusokoneza ma hub bearing kapena kusintha ma sealing rings a ma hub units; apo ayi, ma sealing rings angawonongeke, zomwe zingalole madzi kapena fumbi kulowa. Ngakhale njira zothamangira za sealing ring ndi mkati mwake zinawonongeka, zomwe zinapangitsa kuti bearing isagwire ntchito kwamuyaya.
Pali mphete yolumikizira maginito mkati mwa mphete yotsekera ya bearing yokhala ndi chipangizo cha ABS. Mphete yolumikizira iyi siyenera kugwedezeka, kukhudzidwa kapena kukhudzana ndi maginito ena. Musanayike, ichotseni m'bokosi lolongedza ndikuisunga kutali ndi maginito, monga ma mota amagetsi kapena zida zamagetsi zomwe zikugwiritsidwa ntchito, ndi zina zotero. Mukayika ma bearing awa, yang'anani singano ya alamu ya ABS pa dashboard kudzera mu mayeso a road condition kuti musinthe momwe ma bearing amagwirira ntchito.
Pa ma hub bearing okhala ndi mphete za ABS magnetic thrust, kuti mudziwe mbali yomwe mphete ya thrust yayikidwapo, mutha kubweretsa chinthu chaching'ono komanso chopepuka pafupi ndi m'mphepete mwa bearing. Mphamvu ya maginito yopangidwa ndi bearing idzachikopa. Mukayika, lozani mbali yokhala ndi mphete ya magnetic thrust mkati, moyang'anizana mwachindunji ndi zigawo zomvera za ABS. Kuyika kolakwika kungayambitse kulephera kwa ntchito ya braking system.
Ma bearing ambiri amakhala otsekedwa ndipo safuna mafuta nthawi yonse ya moyo wawo. Ma bearing ena osatsekedwa, monga ma bearing a roller okhala ndi mizere iwiri, ayenera kudzozedwa ndi mafuta panthawi yoyika. Chifukwa cha kukula kosiyanasiyana kwa mabowo amkati mwa ma bearing, zimakhala zovuta kudziwa kuchuluka kwa mafuta oti muwonjezere. Chofunika kwambiri ndikuwonetsetsa kuti pali mafuta mu ma bearing. Ngati pali mafuta ambiri, ma bearing akazungulira, mafuta ochulukirapo adzatuluka. Chidziwitso chonse: Pakuyika, mafuta onse ayenera kukhala 50% ya malo olowera.
Mukayika ma lock nati, kukula kwa torque kumasiyana kwambiri chifukwa cha kusiyana kwa mitundu ya ma bearing ndi ma bearing housings. Chonde onani malangizo oyenera.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
