Nissan Qashqai Silent Blocks

Panthawi yoyendetsa galimotoyo, zigawo zake ndi zigawo zake zimakhala ndi katundu wogwedezeka. Pakapita nthawi, kugwedezeka kwamakina kwamitundu yosiyanasiyana kumayambitsa kuwonongeka kwa magawo a magwiridwe antchito agalimoto.

Kuti muchepetse kugwedezeka ndi kugwedezeka pamapangidwe agalimoto, zinthu zapadera zimagwiritsidwa ntchito - midadada yopanda phokoso (rabara yosalekanitsidwa ndi mahinji achitsulo). Malinga ndi eni magalimoto ambiri, midadada chete pamagalimoto a Nissan Qashqai ndi malo ofooka.

Mfundo zambiri

Chotchinga chopanda phokoso ndi chinthu chosalekanitsidwa chotsutsana ndi kugwedezeka chomwe chili ndi zitsulo ziwiri zachitsulo (mkati ndi kunja). Pakati pawo, tchire limalumikizidwa ndi vulcanized wosanjikiza wa elastomer (rabara kapena polyurethane). Ntchito yayikulu ya cholumikizira chotanuka ndikuyamwa ndikuchotsa kugwedezeka komwe kumawonedwa.

Vibration isolators amagwiritsidwa ntchito kutsogolo ndi kumbuyo kuyimitsidwa mikono. Iwo amamangiriridwa ku levers, shock absorbers, injini, gearbox, ndege propulsion.

Galimotoyo ikagwiritsidwa ntchito, choyikapo zotanuka pakati pa nthiti zopanda phokoso pang'onopang'ono chimayamba kusweka ndi kugwa. Pamene kuvala kumawonjezeka, elastomer imatenga kugwedezeka pang'ono, komwe kumakhudza nthawi yomweyo khalidwe la makina.

Moyo mwadzina komanso weniweni wa zodzipatula za vibration

Chida chodziwika bwino cha block block chapangidwira ma kilomita 100. Komabe, malinga ndi misewu yapakhomo, nthawi yovomerezeka yosinthira zinthuzi ndi makilomita 50 aliwonse.

Kuwona kothandiza kumawonetsanso zida zotsika zamagulu amtundu wa zodzipatula zomwe zimayikidwa pamagalimoto a Nissan Qashqai. Choncho, moyo wautumiki wa midadada chete ya levers kutsogolo zimasiyanasiyana makilomita 30, ndi kumbuyo midadada chete ya subframe kutsogolo - ndi makilomita zikwi 40.

Zizindikiro za kuvala kapena kulephera kwa midadada chete

Mfundo yakuti midadada mwakachetechete wa Nissan Qashqai subframe kapena zigawo zake zina amafuna kufufuzidwa mosamala ndi zotheka wotsatira m'malo zikusonyezedwa ndi zizindikiro zotsatirazi:

• kuchepetsa kuyendetsa galimoto;
•  kuwonongeka kwa controllability;
• mabuleki osagwirizana;
• kuonjezera liwiro la zomwe zimayendera pa chiwongolero;
• kokerani galimoto kumbali pamene mukuyendetsa pa liwiro lalikulu;
• kugwedezeka ndi kugwedezeka kwa thupi pamene mukuyendetsa galimoto;
• matayala osagwirizana.

Kunyalanyaza zizindikiro zoterezi n'koopsa kwambiri. Kuwonongeka kwa magwiridwe antchito a midadada chete sikungopangitsa kuti pakhale kutha msanga kwa zida zamagalimoto ndi njira zamagalimoto, komanso kuchepa kwa kuwongolera kwake. Pamodzi, kusintha kumeneku kungayambitse ngozi.

Kuphatikiza pa ngozi yachitetezo kwa dalaivala, ma bushings ovala amatha kuwononga mbali zina ndi njira. Izi zikuwopseza kukonzanso kokwera mtengo, mpaka kusinthidwa kwathunthu kwa magawo ogwira ntchito.

Mutha kuwunika paokha momwe ma vibration isolators akuyendera poyang'ana chassis. Kuti muchite izi, galimotoyo imayikidwa mu elevator kapena pamwamba pa gazebo. Chotsani zida za mpira ngati kuli kofunikira.

Kenako, mawonekedwe a magawo omwe amagwira ntchito ndi ma block osalankhula amawunikidwa:

1. gwedezani mikono yoyimitsidwa - manja ogwiritsidwa ntchito samamira, koma, atalumpha, abwerere ku malo awo oyambirira;
2. yang'anani manja: sayenera kusinthasintha pokhudzana ndi zotuluka;
3. yang'anani chinthu chodzipatula chogwedezeka chokha kuti chikhale ndi ming'alu ndi mapindikidwe;
4. fufuzani ngati pali sewero lililonse m'mabwalo opanda phokoso - akakulirakulira, m'pamene angafunikire kusinthidwa.

Chabwino n'chiti: polyurethane kapena mphira mankhwala?

Kutengera ndi elastomer yomwe imagwiritsidwa ntchito pakati pa tchire, kusiyana kumapangidwa pakati pa polyurethane ndi mphira.

Zogulitsa za polyurethane ndizokwera mtengo, koma zili ndi zabwino monga:

• mkulu mlingo wa mphamvu;
• moyo wautali wautumiki (pafupifupi nthawi 5;
•  kukana kutentha kochepa.

Zogulitsa zoterezi nthawi zambiri zimagwiritsidwa ntchito pothamanga magalimoto. Iwo ali mulingo woyenera kwambiri m'malo ovuta kwambiri ogwirira ntchito, pomwe kuyimitsidwa kolimba komanso kuyendetsa bwino galimoto ndikofunikira.

Zodzipatula za rabara kugwedera ndizochepa, koma zotsika mtengo. Rubber, mosiyana ndi polyurethane, imatha kupsa mtima komanso kuvala. Komabe, panthawi imodzimodziyo, mankhwala a mphira amapereka galimotoyo kuyenda bwino komanso kuyendetsa bwino.

Choncho, posankha midadada yabwino "Nissan Qashqai chete", m'pofunika kuganizira mmene ntchito galimoto. Ngati amafunikira mphamvu yayikulu pamakina, ndiye kuti njira yabwino ndiyo kugula zinthu za polyurethane. Ngati crossover ikugwiritsidwa ntchito mosalala, zodzipatula za rabara za vibration ndizoyenera.

Kusintha zolumikizira zopanda phokoso za machirawo

Pamagalimoto a Nissan Qashqai, pali zinthu 4 zotsutsana ndi kugwedezeka pagawo laling'ono. Kuti muwonjezere gwero lathunthu, ndikofunikira kusintha zinthu zonse nthawi imodzi.

Nambala zamakalata zovomerezeka za zida zosinthira: 54466-JD000 - kutsogolo; 54467-BR00A - kumbuyo.

Kusintha kumachitika motere:

1. galimotoyo imayikidwa pamtunda kapena pa wowonera;
2. ikani chiwongolero mu "mowongoka" malo;
3. chotsani tsinde lapakati;
4. masulani bawuti kuti mulumikizane ndi chowongolera ndi hinge;
5. chotsani mphira wa rabara ku bulaketi;
6. chotsani pivot pin;
7.  kugawaniza zothandizira ndi mpira;
8. subframe ndi disassembled;
9. gwiritsani ntchito nyundo kapena nyundo kuti muchotse tchire lomwe latha.

Kenako yikani gawo latsopano lolowa m'malo ndikusonkhanitsa gululo motsatira dongosolo.

Kusintha midadada mwakachetechete wa kutsogolo kuyimitsidwa mkono

Kuti m'malo zodzipatula kugwedezeka kwa mikono yakutsogolo, m'pofunika kukhazikitsa makina pa lift kapena pa TV woonera. Chotsani gudumu kumbali yomwe ikukonzedwa.

Patsogolo pake:

1. chotsani mtedza wa mpira;
2. kumasula mpira;
3. masulani ma bolts a vibration isolator (choyamba kutsogolo, kenako kumbuyo);
4. chotsani lever;
5. kanikizani chodzipatula chakale cha vibration mu atolankhani kapena kuchimenya ndi mallet;
6. chopatula chatsopano cha vibration chimakanikizidwa ndipo msonkhanowo umasonkhanitsidwa.
