Silent block Nissan Qashqai

Munguva yekushanda kwemotokari, zvikamu zvaro zvekugadzirisa uye zvikamu zvinoiswa pasi pekutakura mitoro. Nokufamba kwenguva, ma mechanical vibrations emhando dzakasiyana-siyana dzekusimba zvinotungamirira mukuparadzwa kwezvikamu zvezvikamu zvinoshanda zvemotokari.

Kuyera vibrations uye vibrations mukugadzirwa kwemotokari, zvinhu zvakakosha zvinoshandiswa - zvidhinha zvinyararire (zvisinga patsanurwe rabha uye simbi hinges). Sekureva kwevaridzi vemotokari vazhinji, zvivharo zvinyararire pamotokari dzeNissan Qashqai inzvimbo isina simba.

General information

Iyo yakanyarara block ndeye isinga patsanurwe anti-vibration element ine maviri simbi bushings (yemukati nekunze). Pakati pavo, mabhushi akabatanidzwa ne vulcanized layer ye elastomer (rabha kana polyurethane). Basa guru rekuisa elastic ndere kutora uye kubvisa zvinoonekwa kudengenyeka.

Vibration isolators inoshandiswa kumberi uye kumashure ekumisa maoko. Iwo akabatanidzwa kune levers, shock absorbers, injini, gearbox, jet propulsion.

Sezvo motokari inoshandiswa, iyo elastic inopinza pakati pemakwenzi ezvivharo zvinyararire zvishoma nezvishoma inotanga kuputika uye kuparara. Sezvo kupfeka kunowedzera, elastomer inotora zvishoma uye zvishoma kudengenyeka, izvo zvinokanganisa pakarepo maitiro emuchina.

Nominal uye chaiyo hupenyu hwe vibration isolators

Iyo yezita sosi yemabhururu akanyarara akagadzirirwa 100 zviuru zvemakiromita. Nekudaro, pasi pemamiriro emigwagwa yemumba, iyo yakakurudzirwa yekutsiva nguva yezvinhu izvi ndeye 50 zviuru zvemakiromita.

Kucherekedza kunoshanda kunoratidzawo yakaderera sosi yemapoka ega ega ezvivhitivhiti zvitsaurwa zvakaiswa pamotokari dzeNissan Qashqai. Saka, hupenyu hwesevhisi yezvivharo zvinyararire zvemberi zvinosiyana nemakiromita zviuru makumi matatu chete, uye kumashure kunyarara zvidhinha zvepamberi subframe - nezviuru makumi mana zvemakiromita.

Zviratidzo zvekupfeka kana kukundikana kwezvivharo zvinyararire

Icho chokwadi chekuti bushings yeNissan Qashqai subframe kana zvimwe zvikamu zvadzo zvinoda kunyatsoongororwa nekugona kutsiva kunotevera kunoratidzwa nezviratidzo zvinotevera:

• kuderedzwa kwekufambisa kwemotokari;
•  kuderera kwekutonga;
• uneven braking;
• kuwedzera kumhanya kwekuita kwekutakura kune chidhiraivho;
• dhonza mota parutivi paunenge uchityaira zvakanyanya;
• jerks uye kudengenyeka kwemuviri paunenge uchityaira;
• kusaenzana kwematayi.

Kufuratira zviratidzo zvakadaro kune ngozi zvikuru. Kushatisa kwemaitiro ekushanda kwezvivharo zvinyararire zvinotungamira kwete kungopfeka nguva isati yakwana yezvikamu zvechimiro uye magadzirirwo emota, asiwo nekuderera kwekudzora kwayo. Pamwe chete, shanduko idzi dzinogona kukonzera emergency.

Mukuwedzera kune njodzi yekuchengetedza mutyairi, mabhushi akasakara anogona kukonzera kuparadzwa kwezvimwe zvikamu uye michina. Izvi zvinotyisidzira nekugadzirisa kunodhura, kusvika pakutsiviwa kwakakwana kwezvikamu zvekushanda.

Diagnostics

Iwe unogona kuzvimiririra kuongorora mamiriro eiyo vibration isolators nekuita ongororo yekuona yechassis. Kuti uite izvi, motokari inoiswa muelevator kana pamusoro pe gazebo. Bvisa majoini ebhora kana zvichidiwa.

Tevere, mamiriro ezvikamu zvinoshanda zvine hukama nemabhururu akanyarara anoongororwa:

1. zunza maoko ekumisa - maoko anoshandirwa haanyure, asi, asvetuka, dzokera kunzvimbo yavo yepakutanga;
2. ongorora sleeve: haifaniri kutenderera maererano neprotrusions;
3. ongorora vibration yekuzvitsaura chinhu pachayo kune makatsemuka uye deformation;
4. tarisa kana paine chero yekutamba mumabhururu akanyarara - iyo yakakura, nekukurumidza ichada kutsiviwa.

Ndezvipi zviri nani: polyurethane kana zvigadzirwa zverabha?

Zvichienderana ne elastomer inoshandiswa pakati pemakwenzi, mutsauko unoitwa pakati pe polyurethane uye rubber bushings.

Polyurethane zvigadzirwa zvinodhura zvakanyanya, asi zvine zvakanakira senge:

• simba rakakwirira;
• hupenyu hurefu hwebasa (anenge ka5;
•  kushorwa kune tembiricha yakaderera.

Zvigadzirwa zvakadaro zvinowanzo shandiswa kumhanyisa mota. Izvo zvakanyanya mumamiriro ezvinhu akaoma ekushanda, uko kuoma kwekumiswa uye kunyatsobata motokari kwakakosha.

Rubber vibration isolators haina kusimba, asi inokwanisika. Rubber, kusiyana nepolyurethane, inotarisana nekukurumidzira abrasion uye kupfeka. Zvisinei, panguva imwecheteyo, zvigadzirwa zverabha zvinopa motokari kufamba kwakapfava uye kubata kwakapfava.

Nokudaro, pakusarudza zvakakodzera Nissan Qashqai zvidhinha zvinyararire, zvinokurudzirwa kutarisa mamiriro ekushanda kwemotokari. Kana vachida simba rakawanda kubva pamushini, saka mhinduro inonzwisisika ingave yekutenga zvigadzirwa zve polyurethane. Kana iyo crossover ichishandiswa mune yakatsetseka modhi, rubber vibration isolators ndiyo yakakwana.

Kutsiva mabhuroko akanyarara emutambara

Pamotokari dzeNissan Qashqai, pane 4 anti-vibration zvinhu pane subframe. Kuti uwedzere iyo yakazara sosi, zvinodikanwa kutsiva zvese zvinhu kamwechete.

Yakakurudzirwa nhamba dzekaroti dzezvikamu zvakasara: 54466-JD000 - mberi; 54467-BR00A - kumashure.

Kutsiva kunoitwa zvinotevera:

1. iyo motokari inogadziriswa pamusoro pekusimudza kana pane muoni;
2. isa chidhiraivho munzvimbo "yakatwasuka";
3. bvisa shaft yepakati;
4. sunungura bhaudhi kuchengetedza kubatana kwechidhiraivho uye hinge;
5. bvisa pedhi yerabha kubva pachigadziko;
6. bvisa pivot pin;
7.  disassemble zvinotsigira uye bhora;
8. iyo subframe inoparadzaniswa;
9. shandisa kukukurwa kana sando kubvisa gwenzi rasakara.

Wobva waisa chikamu chitsva chekutsiva uye unganidza gungano mune reverse order.

Kutsiva mabhuroko akanyarara eruwoko rwemberi rwakarembera

Kutsiva vibration isolators yemaoko epamberi, zvinodikanwa kuisa muchina pakusimudza kana paTV muoni. Bvisa gumbo kubva kudivi riri kugadziriswa.

Kure:

1. sunungura nzungu yebhora;
2. kusunungura bhora;
3. sunungura mabhaudhi eiyo vibration isolator (kutanga kumberi, ipapo kumashure);
4. bvisa lever;
5. dzvanya iyo yekare vibration isolator mumuchina kana kuirova nemallet;
6. itsva vibration isolator inotsikirirwa mukati uye gungano rinounganidzwa.
