Sekela i-bearing strut

I-absorber yokusekela ye-front suspension strut yemoto isebenza ukunikeza uxhumano oluguquguqukayo phakathi kwe-shock absorber kanye nomzimba wemoto. Okusho ukuthi, itholakala phezulu kwe-strut, phakathi kwendebe engaphezulu yesiphethu esimanzi kanye nokusekela.

Ngokwesakhiwo, umhlangano uwuhlobo oluthile lwe-rolling bear. Nokho, isici sayo ukujiya okukhulu kwendandatho yangaphandle. Ama-rollers angama-cylindrical asebenza njengezinto ezigoqayo kuleli cala. Zitholakala perpendicular komunye nomunye, futhi futhi ahlukaniswe nomunye. Lo mklamo wedivayisi unikeza ikhono lokuthatha imithwalo kusuka kunoma iyiphi indlela.

Kusizakala ngani ukwesekwa?

Ukusekela ukusebenza kokuthwala

umsebenzi oyisisekelo we-thrust bear vumela i-shock absorber ukuthi ijikeleze ngokukhululekile ekusekeleni. Kungakhathalekile ukuthi hlobo luni lomklamo wokusekela, luhlala lukhona ngenhla nje kwentwasahlobo yangaphambili, futhi induku ye-shock absorber idlula emgodini wayo ophakathi. I-shock absorber housing inamathele emzimbeni wemoto lapho kufakwe khona i-thrust bear. Ihlinzeka ngoxhumano olunyakazayo phakathi kwe-shock absorber kanye nomzimba wemoto.. Ngakho-ke, ukuthwala ngesikhathi sokusebenza akukona nje kuphela i-radial, kodwa futhi nemithwalo ye-axial.

Izinhlobo zamabhere wokusekela

Kuye ngomklamo, namuhla kunezinhlobo eziningana zama-thrust bearings. Phakathi kwazo:

Izinhlobonhlobo zama-thrust bearings

• Ngendandatho eyakhelwe ngaphakathi yangaphandle noma yangaphakathi. Ifakwe kusetshenziswa izimbobo ezifakwa ezindlini, okungukuthi, ayidingi ukusebenzisa ama-clamping flanges.
• Ngendandatho yangaphakathi ekhiphekayo. Umklamo usho ukuthi iringi yangaphandle ixhunywe endlini. ngokuvamile, i-thrust bearing enjalo isetshenziswa lapho ukunemba kokujikeleza kwamasongo angaphandle kubalulekile.
• Ngendandatho yangaphandle ekhiphekayo. Okungukuthi, okuphambene nedlule. Kulesi simo, indandatho yangaphandle ihlukaniswe futhi indandatho yangaphakathi ixhunywe endlini. Lolu hlobo lokuthwala lusetshenziswa uma kudingeka ukunemba kokujikeleza kweringi yangaphakathi.
• Ukuhlukaniswa ngakunye. Lapha, umklamo uhilela ukuhlukanisa indandatho yangaphandle ngesikhathi esisodwa. Lesi sixazululo sinikeza ukuqina okwandisiwe. Lolu hlobo lokuthwala lusetshenziswa ezimweni lapho kudingekile ukuqinisekisa ukujikeleza kwendandatho yangaphandle ngokunemba okwanele.

Kungakhathaliseki ukuthi iklanywe kanjani, ukungcola nesihlabathi kusangena ngaphakathi kanye nomswakama futhi yizici eziyinhloko ezilimazayo kanye nokushaqeka okunamandla kokumiswa.

Impilo yesevisi ye-shock absorber support bear yakhelwe ukuba ibe ngaphezu kwe-100 km.

Izimpawu zokuphonsa okuhlulekile

Izimpawu zokugqokwa yizici ezimbili eziyisisekelo - ukuba khona kokungqongqoza lapho uphendula isondo endaweni yamasondo angaphambili (futhi azwakala esondweni kwezinye izimo), kanye nokuwohloka kwesondo. ukulawulwa komshini. Kodwa-ke, ukungqongqoza okuvela kuma-racks ngezinye izikhathi kungase kungezwakali. Kuncike ekuklanyweni kwabo.

Ukuthwala ukwesekwa okugugile

Isibonelo, emotweni ye-VAZ-2110, umjaho wangaphakathi we-thrust bear usebenza njengomkhono lapho kudlula khona induku ye-shock absorber. Lapho i-bearing igugile ngokwanele, izindlu zayo zivumela ukudlala, lapho induku ye-shock absorber iphuma e-axis. Ngenxa yalokhu, kukhona ukwephulwa kwama-engeli wokugoqa-ukuhlangana. Ukuhlukana kungabonwa ngokunyakazisa imoto. Uzothola imiyalelo enemininingwane mayelana nokuhlola ukwesekwa okutholakala endabeni yokwengeza.

Isibonakaliso esiyinhloko sokuwohloka isidingo sokuhlala uqondisa lapho ushayela emgwaqeni oqondile. Ngenxa yokwephulwa kwe-engeli ye-toe-in, ukugqokwa kokusekelwa kwe-shock absorber kukhula cishe ngo-15 ... 20%. abavikeli bamathayi, okuxhumayo nezinduku zokuqondisa, amathiphu abo nawo ayaguga ngaphezu kwalokho.

Uma imisebenzi ye-bearing ihlanganisa kuphela ukujikeleza kwe-strut (okungukuthi, ayihlanganisi ne-absorber shock), khona-ke kulokhu akukho ukwephulwa kwama-angles-in-engeli, ngoba induku yokudonsa ukushaqeka ibamba i-bushing. , ecindezelwa ku-damper yerabha yesakhiwo (isibonelo, "Lada Priora", "Kalina", "Nissan X-Trail". Nokho, lokhu kusathinta ukuphathwa kwemoto, nakuba ngezinga elincane. Umphumela onjalo uzoqala ukukhuphuka uma uhluleka. Ngaphezu kwalokho, ukungqongqoza kuvame ukuzwakala ngisho nasesondo lokushayela. Kulokhu, ngeke kusebenze ukuhlonza ukwehluleka kokuthwala ngokumane ujike imoto..

Izinkinga zomsebenzi we-EP nemiphumela yazo

Ukusekela ukusebenza kokuthwala

I-suspension strut support bearing ingaphansi kokusetshenziswa kanzima. Ikakhulukazi uma ushayela emigwaqeni emibi, ugoqa amakhona ngesivinini esikhulu, ukungahambisani nesivinini esinqunyelwe umshayeli. Isimo sibhebhetheka yiqiniso lokuthi ama-bearings amaningi (kodwa hhayi wonke) awaklanyelwe ukuvikelwa othulini, umswakama kanye nokungcola. Ngakho-ke, ngokuhamba kwesikhathi, kwakheka inqwaba ye-abrasive kuzo, esheshisa ukugqokwa komshini wabo. Uma ukuklanywa kwama-bearings akho kuhlinzeka ngokuba khona kwezigqoko zokuzivikela, kodwa azikho (zazilahlekile), qiniseka ukuthi uyala amasha. lokhu kuzokwandisa impilo yokuthwala. Futhi ungakhohlwa ukufaka amafutha ku-bearing, sizoxoxa kabanzi ngalokhu.

Kunconywa ukuthi uhlole isimo samabheringi okusekela njalo ngamakhilomitha angu-20, ngaphandle uma kucaciswe ngenye indlela umkhiqizi wemoto.

Ngakho-ke, izizathu eziyinhloko zokuhluleka kwama-thrust bears yizizathu ezilandelayo:

Uhlelo OP

• Ukugqokwa kwemvelo kwengxenye. Njengoba kushiwo ngenhla, ukushintshwa kwama-thrust bearings kufanele kwenziwe okungenani njalo ngamakhilomitha ayizinkulungwane eziyi-100 wemoto (imvamisa kaningi, uma kubhekwa isimo semigwaqo yasekhaya).
• Isitayela sokushayela esinzima kanye nokungathobeli umkhawulo wesivinini. Esimweni lapho umshayeli eshayela ngesivinini esikhulu emigodini noma engena ekujikeni, khona-ke umthwalo kuwo wonke ukumiswa kwemoto, kanye nokusekelwa okusekelwe, ikakhulukazi, kwanda kakhulu. Futhi lokhu kuholela ekugqokeni kwayo ngokweqile.
• Ikhwalithi ephansi yengxenye. Uma unquma ukonga imali futhi uthenge inkohliso yekhwalithi ephansi, khona-ke kukhona amathuba aphezulu okuthi ukuthwala akuphumi esikhathini esikhonjiswe ekufakweni kwayo.
• Izimo zokusebenza kwemoto. Kuye ngezimo umshini oklanyelwe zona nokuthi usetshenziswa kanjani, ukwehluleka ukuthwala ukusekela kungase kwenzeke ngokushesha kakhulu kunalokho okubikezelwe umenzi.

Lapho wenza umsebenzi wokulungisa ku-shock absorber, i-suspension strut nezinye izingxenye ezihlobene, sincoma ukuthi ubeke amafutha ekuthwaleni ukwesekwa. Lokhu kuzokwandisa impilo yayo yesevisi, kanye nokunciphisa umthwalo kuzo zonke izakhi ezibalwe ngenhla.

Ukusekela ukuthambisa ukuthambisa

Emgogodleni wayo, i-thrust bear iyi-bearing eginqikayo. Ukuze kuncishiswe umthwalo kuwo ngesikhathi sokusebenza, kanye nokwandisa impilo yenkonzo, kusetshenziswa ama-lubricant ahlukahlukene. Ukugcoba ama-thrust bearings, izinhlobo zabo zepulasitiki zivame ukusetshenziswa. Amafutha enzelwe ukuthuthukisa ukusebenza kwama-bearings. okungukuthi:

• ukwandisa ukuphila kokuzala futhi andise impilo yayo yesevisi;
• ukunciphisa umthwalo kumayunithi wokumiswa (hhayi kuphela ekuthwaleni, kodwa nakwezinye izakhi - ukuqondisa, i-axle, ukuqondisa nokuxhuma izinduku, amathiphu, njalonjalo);
• ukwandisa ukulawuleka kwemoto (ungakuvumeli kwehle ngesikhathi sokusebenza).

Uhlobo ngalunye lwe-lubricant lunezici zalo, izinzuzo kanye nokubi. Ngakho-ke, kubalulekile ukukhetha i-lubricant eyodwa noma enye, kucatshangelwa izizathu ezilandelayo:

• imithwalo ethile esebenza ekuthwaleni ukwesekwa (isisindo semoto, izimo zayo zokusebenza);
• Amathuba okungena / ku-node yomswakama;
• amazinga okushisa avamile futhi aphezulu okusebenza lapho i-bearing yakhelwe;
• izinto okwenziwa ngazo izindawo zokusebenza zokuhlangana (insimbi-insimbi, insimbi-ipulasitiki, ipulasitiki-ipulasitiki, irabha yensimbi);
• ubunjalo bamandla okungqubuzana.

Ezweni lethu, ama-lubricant adumile e-thrust bear yilewa alandelayo:

• I-LITOL 24. Lawa mafutha alula, afakazelwe futhi ashibhile alungele ukubekeka endaweni yokusekela njengenye yezinhlobo eziningi zama-bearings okuhloswe wona lawa mafutha.
• Ama-lubricant ahlukahlukene amajoyinti e-CV. Uzothola ulwazi oluningiliziwe mayelana nemikhiqizo edumile, izinzuzo zayo kanye nokubi endabeni yokwengeza.
• Amafutha e-lithium ngokungezwa kwe-molybdenum disulphide. Ziningi izingoma ezinjalo. Enye yezinhlobo ezidumile yi-Liqui Moly LM47. Nokho, khumbula ukuthi lezi ama-lubricant esaba umswakama, ngakho-ke angasetshenziswa kuphela kuma-thrust bearings anezigqoko zokuzivikela.
• futhi, abashayeli abaningi basebenzisa elinye lamagrisi e-Chevron's multipurpose: amnyama I-Black Pearl Grease EP 2, ne-blue Delo Grease EP NLGI 2. Womabili amagrisi aku-397 g amashubhu.

Abanikazi beFord Focus bazo zonke izizukulwane bayelulekwa ngokuqinile ukuthi bahlole ukuba khona kwamafutha kuma-thrust bearings amasha nasetshenzisiwe. Ngakho-ke, lapho kuvela i-crunch encane, qiniseka ukuthi uhlola isimo sokuthwala futhi usigcwalise ngamafutha.

Kodwa-ke, kungakhathaliseki ukuthi kungenzeka, ngisho nokusetshenziswa kokugcoba, noma yikuphi ukuthwala kunomthombo wayo olinganiselwe. Ngokuvamile, ukushintshwa kwe-thrust bear kwenziwa kanye nokushintshwa kwe-absorber shock, uma kunesidingo esinjalo.

Kumiselela ukuthwala kokusekelwa

Ukushintshwa kwe-OP

Ngokuhluleka okuphelele noma okuyingxenye kokuthwala, akekho ohlanganyela ekulungiseni kwayo, ngoba akukho lutho olulungiswayo. Nokho, ungakwazi ukuqeda ukungqongqoza okuvame ukubakhathaza abanikazi bezimoto. okungukuthi, ngesikhathi sokusebenza, irabha ye-damper "iyacwila", futhi kwakhiwa i-backlash. Ngenxa yalokho, kukhona ukungqongqoza. Ungacabangela indlela yokuqeda le nkinga usebenzisa isibonelo se-VAZ 2110 kuvidiyo elandelayo.

I-thrust bear ifakwe ezimotweni ezine-MacPherson strut front suspension. Ngakho-ke, inqubo yokuyishintsha iyafana ezinyathelweni eziningi, ngaphandle komehluko omncane ekusetshenzisweni kwezinye izingxenye zamamodeli emoto ngayinye. Kunezindlela ezimbili zokushintshwa - ngokudilizwa ngokuphelele komhlangano we-rack noma ngokususa ingxenye ephezulu yomhlangano we-rack. ngokuvamile, basebenzisa inketho yokuqala, esizoyichaza ngokuningiliziwe.

Uma ukushintshwa kwe-OP kungenzeka ngaphandle kokudiliza i-rack, umsebenzi wenziwa kalula. Udinga nje ukususa indebe kanye ne-bearing endala bese ufaka entsha. Uma ukuklama nendawo yokusekela ukusekela akuvumeli lokhu, khona-ke uzodinga amathuluzi wokukhiya, kanye ne-jack, ama-wrenches kanye nezibopho zasentwasahlobo ukuze uqedele umsebenzi.

Qinisekisa ukuthi unezibopho zasentwasahlobo, ngoba ngaphandle kwazo ngeke ukwazi ukususa i-thrust bear yakudala.

I-algorithm yokufaka esikhundleni se-thrust bear lapho ususa i-strut futhi uqaqa i-absorber shock imi kanje:

1. Khulula amantongomane asekelayo (imvamisa akhona amathathu, atholakala ngaphansi kwe-hood).
2. Gcoba imoto eceleni lapho kufanele kushintshwe khona i-bearing, bese ususa isondo.
3. Khipha i-hub nut (imvamisa iyaphinwa, ngakho-ke udinga ukusebenzisa ithuluzi lomthelela).
4. Khulula i-strut mount engezansi futhi ukhulule inadi elingezansi kancane.
5. Nqamula i-brake caliper, bese uyihambisa eceleni, kuyilapho ukunqamula i-hose ye-brake akudingekile.
6. Usebenzisa i-crowbar noma i-pry bar, susa ama-rack mounts aphansi esihlalweni.
7. Susa umhlangano we-strut emzimbeni wemoto.
8. Ukusebenzisa ama-couplers akhona, qinisa iziphethu, emva kwalokho udinga ukuhlukanisa i-strut yokumiswa.
9. Ngemva kwalokho, inqubo eqondile yokufaka esikhundleni sokuthwala iyenziwa.
10. Ukuhlanganiswa kwesistimu kwenziwa ngokulandelana okuphambene.

Ukushintshwa kwe-OP ngaphandle kokuwa ku-VAZ 2108-21099, 2113-2115.

Ukushintsha i-OP nge-VAZ 2110

Yikuphi ukusekelwa okuphathelene nokukhetha

Okokugcina, amagama ambalwa mayelana nokuthi yimaphi ama-bearings angcono kakhulu ongawasebenzisa. Okokuqala, udinga ukuqonda ukuthi konke kuncike imodeli imoto yakho. Ngakho-ke, akunakwenzeka ukunikeza izincomo ezicacile. Ngokufanelekile, udinga ukwakha phezu kolwazi olunikezwe umenzi wemoto yakho.

Imvamisa, okwamanje, akuwona ama-bearings asekelayo ngokwawo athengiswayo, kodwa ikhithi eyakhiwe ngaphambilini ehlanganisa ukwesekwa kanye ne-bearing.

Abakhiqizi bezimpahla ezidumile:

• I-SM wumkhiqizo waseShayina owasungulwa ngo-2005. Iyingxenye yentengo emaphakathi. Ngaphezu kwama-bearings, ezinye izingxenye ezisele zemishini ehlukahlukene nazo ziyakhiqizwa.
• Lemforder - inkampani yaseJalimane edume ngekhwalithi yayo, ikhiqiza cishe lonke uhla lwezingxenye zezimoto.
• I-SNR yinkampani yaseFrance edume umhlaba wonke ekhiqiza ama-bearings ahlukahlukene.
• SKF ingumkhiqizi omkhulu kunawo wonke emhlabeni wama-bearings wezimoto nezinye izinto zokusebenza.
• I-FAG yinkampani ezinze eJalimane. Imikhiqizo ihlukaniswa ngekhwalithi nokuthembeka.
• I-NSK, NTN, Kowo - abakhiqizi abathathu abafanayo abavela eJapan. Nikeza izinhlobonhlobo eziningi kanye nekhwalithi yamabheringi akhiqizwayo.

Lapho ukhetha, udinga ukuqonda ukuthi akufanelekile ukukhokha ngokweqile ingxenye ebizayo. Ikakhulukazi uma ungumnikazi wemoto yebhajethi. Nokho, ukonga nakho akufanelekile. Kungcono ukukhetha ama-bearings kusukela esigabeni samanani aphakathi. Ungathola ukubuyekezwa nezincomo ekukhetheni i-OP ekugcineni kwesihloko mayelana nokuhlola ama-thrust bearings, isixhumanisi esisinikeze ngenhla.

isiphetho

I-thrust bear iyingxenye encane kodwa ebalulekile yokumiswa. Ukwehluleka kwayo kungaholela emiphumeleni engathandeki ngendlela yokuwohloka kokulawulwa kwemoto kanye nokwanda komthwalo kwezinye, ezibiza kakhulu, izingxenye. Ngakho-ke, khumbula ukuthi kulula futhi kushibhile ukufaka esikhundleni sale ngxenye engabizi kunokulinda ukwehluleka kwezingxenye ezibiza kakhulu zokumiswa kwemoto. Ungakunaki lokhu futhi wenze ukuxilonga okufika ngesikhathi kanye nokushintshwa kwe-OP.
