Nissan Qashqai Silent Blocks

Ngesikhathi sokusebenza kwemoto, izingxenye zayo zesakhiwo kanye nezingxenye zingaphansi kwemithwalo yokudlidliza. Ngokuhamba kwesikhathi, ukudlidliza kwemishini kwamazinga ahlukahlukene okuqina kuholela ekubhujisweni kwezingxenye zamayunithi asebenzayo emoto.

Ukulinganisa ukudlidliza nokudlidliza ekwakhiweni kwemoto, kusetshenziswa izakhi ezikhethekile - amabhlogo athule (injoloba engahlukaniseki namahinge ensimbi). Ngokusho kwabanikazi bezimoto abaningi, amabhulokhi angasho lutho ezimotweni zakwaNissan Qashqai ayindawo engenamandla.

Ulwazi General

Ibhulokhi ethule iyisici esingahlukaniseki sokulwa nokudlidliza esihlanganisa izinsimbi ezimbili zensimbi (zangaphakathi nangaphandle). Phakathi kwabo, ama-bushings axhunywe ungqimba oluvundile lwe-elastomer (irabha noma i-polyurethane). Umsebenzi oyinhloko wokufakwa okunwebekayo ukumunca nokuqeda ukundindizela okubonwayo.

Izihlukanisi zokudlidliza zisetshenziswa ezingalweni ezimiswe ngaphambili nangemuva. Axhunywe kuma-lever, ama-shock absorbers, injini, u-gearbox, i-jet propulsion.

Njengoba kusetshenziswa imoto, ukufakwa okunwebekayo phakathi kwezihlahla zamabhuloki angathuli kancane kancane kuqala ukuqhekeka nokuwa. Njengoba ukugqoka kwanda, i-elastomer idonsa kancane kancane ukundindizela, okuthinta ngokushesha ukuziphatha komshini.

Impilo yangempela neyangempela yezihlukanisi zokudlidliza

Insiza okuzisholo yona yamabhulokhi athule iklanyelwe amakhilomitha ayizinkulungwane eziyi-100. Kodwa-ke, ngaphansi kwezimo zemigwaqo yasekhaya, isikhawu esinconyiwe sokushintshwa kwalezi zakhi sitholakala njalo ngamakhilomitha ayizinkulungwane ezingama-50.

Ukuqaphela okusebenzayo futhi kukhombisa insiza ephansi yeqembu ngalinye lama-vibration isolator afakwe ezimotweni zakwaNissan Qashqai. Ngakho-ke, impilo yesevisi yamabhulokhi athule we-levers yangaphambili ihluka ngamakhilomitha ayizinkulungwane ezingu-30 kuphela, futhi amabhulokhi angemuva athule e-front subframe - ngamakhilomitha ayizinkulungwane ezingu-40.

Izimpawu zokuguga noma ukwehluleka kwamabhlogo athule

Iqiniso lokuthi ama-bushings we-subframe ye-Nissan Qashqai noma ezinye izakhi zawo zidinga ukuxilongwa ngokucophelela ngokushintshwa okungenzeka okulandelayo kufakazelwa yizimpawu ezilandelayo:

• ukunciphisa ukuhamba kwezimoto;
•  ukuwohloka kokulawula;
• i-braking engalingani;
• ukwandisa isivinini sokusabela kokuthutha esondweni lokuqondisa;
• donsa imoto eceleni lapho ushayela ngesivinini esikhulu;
• ama-jerks kanye nokudlidliza komzimba ngenkathi ushayela;
• ukungalingani kwamasondo.

Ukungazinaki izimpawu ezinjalo kuyingozi kakhulu. Ukuwohloka kwezakhiwo zokusebenza zamabhuloki athule akuholeli nje kuphela ekugqokeni kwangaphambi kwesikhathi kwezingxenye zesakhiwo nezindlela zemoto, kodwa futhi nokuncipha kokulawulwa kwayo. Ndawonye, ​​lezi zinguquko zingabangela isimo esiphuthumayo.

Ngaphezu kwengozi yokuphepha yomshayeli, izihlahla ezigugile zingabangela ukucekelwa phansi kwezinye izingxenye nezindlela. Lokhu kusongela ngokulungiswa okumba eqolo, kuze kufike ekushintshweni okuphelele kwamayunithi asebenzayo.

ukuhlola

Ungakwazi ukuhlola ngokuzimela isimo sezihlukanisi zokudlidliza ngokwenza ukuhlola okubonakalayo kwe-chassis. Ukuze wenze lokhu, imoto ifakwe ku-elevator noma phezulu kwe-gazebo. Susa amalunga ebhola uma kunesidingo.

Okulandelayo, isimo sezingxenye ezisebenzayo ezihlobene namabhulokhi athule siyahlolwa:

1. shwiba izingalo zokumiswa - izingalo ezisebenzisekayo azicwili, kepha, lapho zigxumile, zibuyela endaweni yazo yokuqala;
2. hlola umkhono: akufanele ujikeleze ngokuhlobene nama-protrusions;
3. hlola isici sokudlidliza esizihlukanisayo ngokwaso ukuze uthole imifantu nokonakala;
4. hlola ukuthi ukhona yini umdlalo kumabhulokhi athule - uma umkhulu, uzodinga ukushintshwa ngokushesha.

Yikuphi okungcono: i-polyurethane noma imikhiqizo yenjoloba?

Ngokuya nge-elastomer esetshenziswa phakathi kwezihlahla, umehluko wenziwa phakathi kwe-polyurethane ne-rubber bushings.

Imikhiqizo ye-polyurethane ibiza kakhulu, kodwa inezinzuzo ezifana nalezi:

• amandla amakhulu;
• impilo yesevisi ende (cishe izikhathi ezi-5;
•  ukumelana namazinga okushisa aphansi.

Imikhiqizo enjalo ivame ukusetshenziselwa ukugijima izimoto. Zilungile ezimeni zokusebenza ezinzima, lapho ukuqina kokumiswa kanye nokulawulwa kwemoto okunembayo kubalulekile.

Izihlukanisi ze-Rubber vibration azihlali isikhathi eside, kodwa zithengeka kakhulu. Irabha, ngokungafani ne-polyurethane, ingaphansi kokuhuzuka nokuguga ngokushesha. Kodwa-ke, ngesikhathi esifanayo, imikhiqizo yenjoloba inikeza imoto ukuhamba okushelelayo nokuphatha okushelelayo.

Ngakho-ke, lapho ukhetha amabhlogo athule e-Nissan Qashqai, kuhle ukugxila ezimweni zokusebenza zemoto. Uma zidinga amandla aphezulu emshinini, khona-ke isisombululo esinengqondo kungaba ukuthenga imikhiqizo ye-polyurethane. Uma i-crossover isebenza ngemodi ebushelelezi, ama-isolator e-rubber vibration alungile.

Ukushintsha amabhlogo athule we-stretcher

Ezimotweni zakwaNissan Qashqai, kunezinto ezi-4 ezilwa nokudlidliza ku-subframe. Ukwandisa insiza ephelele, kuyinto efiselekayo ukushintsha zonke izakhi ngesikhathi esisodwa.

Izinombolo zekhathalogi ezinconyiwe zezingxenye ezisele: 54466-JD000 - ngaphambili; 54467-BR00A - ngemuva.

Ukumiselela kungokulandelayo:

1. imoto igxilile ekuphakameni noma kusibukeli;
2. beka isondo lokuqondisa endaweni "eqondile";
3. susa i-shaft ephakathi;
4. khumula ibhawodi elivikela ukuxhunywa kwendlela yokuqondisa kanye nehinji;
5. susa i-rubber pad kubakaki;
6. susa iphinikhodi ye-pivot;
7.  qaqa izisekelo nebhola;
8. i-subframe iyahlakazwa;
9. sebenzisa i-drift noma isando ukususa isihlahla esigugile.

Bese ufaka ingxenye entsha yokufaka esikhundleni bese uhlanganisa umhlangano ngokulandelana okuhlanekezelwe.

Ukushintsha amabhlogo athule engalo elengayo yangaphambili

Ukushintsha izihlukanisi zokudlidliza zezingalo zangaphambili, kuyadingeka ukufaka umshini ekuphakameni noma kusibukeli se-TV. Susa isondo ohlangothini olulungiswayo.

Kude:

1. khumula nati lebhola;
2. khulula ibhola;
3. khulula amabhawodi we-vibration isolator (okokuqala ngaphambili, ngemuva);
4. susa i-lever;
5. cindezela isihlukanisi esidala sokudlidliza emshinini wokunyathelisa noma usishaye nge-mallet;
6. isihlukanisi esisha sokudlidliza siyacindezelwa futhi umhlangano uyahlanganiswa.
