Nissan Qashqai Silent Blocks

Nakong ea ts'ebetso ea koloi, likarolo tsa eona tsa sebopeho le likarolo li tlas'a meroalo ea vibration. Ha nako e ntse e ea, ho sisinyeha ha mechine ea matla a sa tšoaneng ho lebisa tšenyo ea likarolo tsa likarolo tse sebetsang tsa koloi.

Ho leka-lekanya ho thothomela le ho sisinyeha ha moralo oa koloi, ho sebelisoa likarolo tse khethehileng - li-blocks tse khutsitseng (rabara e sa arohaneng le li-hinges tsa tšepe). Ho ea ka beng ba likoloi ba bangata, li-block tsa likoloi tsa Nissan Qashqai ke ntlha e fokolang haholo.

Boitsebiso bo tloaelehileng

Sebaka se khutsitseng ke ntho e sa arohaneng ea anti-vibration e nang le lihlahla tse peli tsa tšepe (ka hare le ka ntle). Pakeng tsa bona, lihlahla li kopantsoe ke lera le nang le vulcanized ea elastomer (rabara kapa polyurethane). Mosebetsi o ka sehloohong oa ho kenya elasticity ke ho monya le ho qhala li-vibrations tse lemohuoang.

Li-isolators tsa vibration li sebelisoa ka pele le ka morao matsoho a emisitsoeng. Li khomaretsoe ho li-levers, li-shock absorbers, enjene, lebokose la li-gear, li-jet propulsion.

Ha koloi e ntse e sebelisoa, sekhahla se kenang pakeng tsa lihlahla tse khutsitseng se qala ho peperana le ho putlama. Ha moaparo o ntse o eketseha, elastomer e monya ho sisinyeha ho fokolang, ho amang hanghang boitšoaro ba mochini.

Bophelo bo ikhethileng le ba 'nete ba li-isolators tsa vibration

Sesebelisoa se ikhethileng sa li-blocks tse khutsitseng se etselitsoe lik'hilomithara tse likete tse 100. Leha ho le joalo, tlas'a maemo a litsela tsa malapeng, nako e khothalletsoang ea ho fetola likarolo tsena ke lik'hilomithara tse likete tse 50.

Maikutlo a sebetsang a boetse a bontša mohloli o tlase oa lihlopha tse ikemetseng tsa li-vibration tse kentsoeng likoloing tsa Nissan Qashqai. Kahoo, bophelo ba ts'ebeletso ea li-block tsa li-levers tse ka pele bo fapana ka lik'hilomithara tse likete tse 30 feela, 'me likarolo tse ka morao tse khutsitseng tsa subframe e ka pele - ka lik'hilomithara tse likete tse 40.

Matšoao a ho felloa ke matla kapa ho hloleha ha li-blocks tse khutsitseng

Taba ea hore lihlahla tsa subframe ea Nissan Qashqai kapa likarolo tse ling tsa tsona li hloka tlhahlobo e hlokolosi ka phetisetso e ka bang teng e bonts'oa ke matšoao a latelang:

• ho fokotsa matla a ho tsamaisa koloi;
•  ho senyeha ha taolo;
• braking e sa lekanang;
• eketsa lebelo la karabelo ea lipalangoang ho lebili la setereng;
• hulela koloi ka thōko ha u khanna ka lebelo le phahameng;
• ho thothomela le ho thothomela ha 'mele ha u ntse u khanna;
• ho se leka-lekane ha thaere.

Ho hlokomoloha matšoao a joalo ho kotsi haholo. Ho senyeha ha thepa ea ts'ebetso ea li-blocks tse khutsitseng ho lebisa eseng feela ho apara pele ho nako ea likarolo tsa mohaho le mekhoa ea koloi, empa hape le ho fokotseha ha taolo ea eona. Hammoho, liphetoho tsena li ka baka tšohanyetso.

Ntle le kotsi ea polokeho bakeng sa mokhanni, lihlahla tse tsofetseng li ka baka tšenyo ea likarolo tse ling le mekhoa. Sena se sokela ka litokiso tse theko e boima, ho fihlela phetohong e felletseng ea likarolo tse sebetsang.

tlhathoba

U ka lekola ka boikemelo boemo ba li-isolators tsa vibrate ka ho etsa tlhahlobo ea pono ea chassis. Ho etsa sena, koloi e kenngoa ka lifting kapa ka holim'a gazebo. Tlosa li-ball joints ha ho hlokahala.

Ka mor'a moo, boemo ba likarolo tse amanang le li-block tse khutsitseng boa hlahlojoa:

1. ho sotha matsoho a emisitsoeng - matsoho a sebetsang ha a tebe, empa, ha a qhomile, a khutlela sebakeng sa ona sa pele;
2. hlahloba sleeve: ha ea lokela ho potoloha ho ea ka li-protrusions;
3. hlahloba thothomelo e itšehla thajana ka boeona bakeng sa mapetsong le deformation;
4. hlahloba hore na ho na le papali leha e le efe li-blocks tse khutsitseng - ha e kholoanyane, kapele e tla hloka ho nkeloa sebaka.

Ke hofe ho molemo: polyurethane kapa lihlahisoa tsa rabara?

Ho ipapisitse le elastomer e sebelisitsoeng lipakeng tsa lihlahla, phapang e etsoa lipakeng tsa polyurethane le lihlahla tsa rabara.

Lihlahisoa tsa polyurethane li theko e boima haholo, empa li na le melemo e kang:

• matla a phahameng;
• bophelo bo bolelele ba tšebeletso (makhetlo a ka bang 5;
•  ho hanyetsa mocheso o tlase.

Lihlahisoa tse joalo li atisa ho sebelisoa bakeng sa likoloi tsa mabelo. Li nepahetse maemong a thata a ts'ebetso, moo ho satalla ho emisoang le ho ts'oaroa hantle ha koloi ho bohlokoa.

Li-isolator tsa ho thothomela ha rabara ha li tšoarelle nako e telele, empa li theko e tlaase. Rabara, ho fapana le polyurethane, e ka senyeha ka potlako le ho apara. Leha ho le joalo, ka nako e ts'oanang, lihlahisoa tsa rabara li fana ka koloi ka leeto le bonolo le ho tšoara hantle.

Ka hona, ha u khetha li-blocks tse khutsitseng tsa Nissan Qashqai, ho bohlokoa ho tsepamisa maikutlo ho maemo a ts'ebetso ea koloi. Haeba ba hloka matla a mangata ho tloha mochine, joale tharollo e utloahalang e tla ba ho reka lihlahisoa tsa polyurethane. Haeba crossover e sebetsa ka mokhoa o boreleli, li-isolator tsa vibration tsa rabara li nepahetse.

Ho fetola li-blocks tse khutsitseng tsa subframe

Likoloing tsa Nissan Qashqai, ho na le likarolo tse 4 tse khahlanong le ho sisinyeha ho subframe. Ho eketsa lisebelisoa tsohle, ke ntho e lakatsehang ho khutlisa likarolo tsohle hang-hang.

Linomoro tse khothalelitsoeng tsa lethathamo la likarolo tse setseng: 54466-JD000 - pele; 54467-BR00A - ka morao.

Phetoho e tjena:

1. koloi e tsitsitsoe holim'a lift kapa ho seshebelli;
2. beha setereng sebakeng se "otlolohileng";
3. tlosa shaft e bohareng;
4. qhaqha boutu e bolokang khokahanyo ea mochini oa ho tsamaisa le hinge;
5. tlosa letlapa la rabara ka har'a bracket;
6. tlosa pivot pin;
7.  qhaqholla litšehetso le bolo;
8. subframe e qhaqhoa;
9. sebelisa sehoho kapa hamore ho tlosa sehlahla se tsofetseng.

Ebe u kenya karolo e ncha e ncha 'me u bokelle kopano ka tatellano e fapaneng.

Ho fetola li-blocks tse khutsitseng tsa letsoho le ka pele le emisitsoeng

Ho nka sebaka sa li-isolators tsa vibration tsa matsoho a ka pele, ho hlokahala ho kenya mochine holim'a lift kapa ho shebella TV. Tlosa lebili lehlakoreng le ntseng le lokisoa.

Ho feta moo:

1. qhaqha nate ea bolo;
2. lokolla bolo;
3. qhaqha liboutu tsa "vibration isolator" (pele ka pele, ebe ka morao);
4. tlosa lever;
5. tobetsa mochine oa khale oa vibrate o itšehla thajana kapa o o otla ka mallet;
6. ho hatelloa sekhetho se secha sa vibrate 'me kopano ea bokelloa.
