Izici ze-polyurethane ukumiswa kwezimoto
Okuqukethwe
Isidingo sokushintshwa sikhonjiswa ngomsindo oklabalasayo ngenkathi ushayela. Lapho uthenga izingxenye zaseShayina ezisezingeni eliphansi, inkinga ivame ukuvela ngemuva kwezinyanga ezingama-2-3 zokusebenza.
I-polyurethane car suspension iyindlela engabizi kakhulu kunezingxenye zenjoloba. Isiza ukuphatha umshini esimweni sezulu esibi, lapho ushayela ungekho emgwaqeni futhi ihlala isikhathi eside.
Kuyini ukumiswa kwe-polyurethane
Akukho ukumiswa okwenziwe ngokuphelele nge-polyurethane (i-elastomer yokwenziwa enendawo ehlelekayo). I-stabilizer bushing kanye nebhulokhi ethule yenziwa kusuka kule nto. Lesi sakamuva siyisixhumanisi sezinye izingxenye ze-chassis, sithambisa ukushaqeka nokudlidliza ngenkathi ushayela emigwaqweni enezikhisi.
Imikhiqizo ye-polyurethane ifaneleka kakhulu ukushayela endaweni esezingeni eliphansi, ngaphandle komgwaqo, ukudlula okunamandla kanye nokujika okubukhali okuqhubekayo. Izakhiwo ezinjalo zibekwe kakhulu kulezi zimo ezilandelayo:
- ukuthuthukiswa kwezimoto zezemidlalo, abashayeli bazo baphenduka kakhulu futhi badlula omunye nomunye emgqeni;
- ukwandisa ukulawuleka kwemoto kubalandeli bokushayela ngobudlova;
- ukubuyiselwa kokwehla kwentengo emishinini yamamodeli amadala, eye yawohloka ngenxa yokusebenza isikhathi eside.
I-polyurethane ayinambala, kodwa izingxenye eziphuzi, ezimnyama, ezolintshi, ezibomvu, eziluhlaza okwesibhakabhaka ziyathengiswa. Abakhiqizi bahlanganisa ngokukhethekile upende ukukhombisa ubulukhuni.
Imibandela yempilo ende yesevisi
Izingxenye ze-polyurethane zizosebenza okungenani izinkulungwane ezingama-50-100 km ngaphansi kwezimo ezijwayelekile kanye nezinkulungwane ezingama-25-50 km lapho ushayela ngaphandle komgwaqo kanye nesitayela sokushayela esinolaka, uma kuhlangatshezwana nezimo ezimbalwa:
- ukumiswa kwemoto kulungiswe ngokuphelele;
- amabhlogo athule afakwe ngendlela efanele;
- ama-stabilizer mounts aphathwe ngamafutha angangeni manzi;
- ukusebenza kwenziwa emazingeni okushisa angekho ngaphansi kuka -40 °C.
Ukumiswa kwe-muffler kwangaphambili
Futhi okubaluleke kakhulu - izingxenye kufanele zibe zintsha futhi zivela kumkhiqizi othembekile.
Izinzuzo nezingozi nebubi
Izingxenye ze-polyurethane zinezinzuzo ezilandelayo:
- Ihluke ngokumelana nokugqoka okuphezulu. Imikhiqizo ye-polyurethane ephezulu ihlala isikhathi eside kunaleyo eyenziwe ngerabha ethambile.
- Yenza ukumiswa kunwebeka kakhulu. Imoto kulula ukuyishayela emgwaqeni omubi nesimo sezulu (iqhwa, iqhwa, umoya onamandla).
- Babekezelela imiphumela yamakhemikhali, afafazwa kakhulu emigwaqweni ebusika. Irabha yonakala ngokushesha lapho izingxube zokunqanda ukuqhwaza zinamathela.
- Thuthukisa ukuphathwa kwemoto. Ngenxa yokuba khona kwezinhlaka ze-polyurethane ku-suspension, kuba lula kumshayeli ukulawula imoto. Ikwazi ukungena kahle emakhoneni ngesivinini futhi kulula ukudlula amanye.
- Ziguga kancane kunemikhiqizo yerabha ethambile.
- Ifanele ukusetshenziswa ezimeni zezulu ezinzima. I-polyurethane, ngokungafani nerabha, ayiqhekeki emakhazeni futhi ayomi ehlobo elishisayo.
Kodwa izinzuzo azikho ngaphansi kwezinzuzo:
- Abakhiqizi bezimoto abazifaki izingxenye ze-polyurethane, ngakho-ke ngeke ukwazi ukuthenga umkhiqizo wangempela. Kunengozi enkulu yokungena emgunyathi wekhwalithi ephansi.
- I-suspension iba nokunwebeka kakhulu, ngakho-ke umshayeli uzozwa wonke ama-bump ngenkathi eshayela emigwaqweni emibi.
- Izingxenye ze-polyurethane zingaqhuma lapho kubanda kakhulu (ngaphansi kuka-40°C). Imikhiqizo esezingeni eliphansi ayikwazi ukumelana no-20 ° C.
- Zibiza ngaphezu kwezakhiwo zokuqala zenjoloba (kodwa azikho ngaphansi ekusebenzeni).
- I-polyurethane ithinta kabi izinzile zensimbi, ngakho-ke kuzodingeka zishintshwe kaningi.
Futhi, i-polyurethane ayihambisani kahle nensimbi futhi ingaphuma kuyo. Ngokuvamile, kungenxa yalesi sizathu ukuthi amabhulokhi amasha athule kufanele afakwe.
Isidingo sokushintshwa sikhonjiswa ngomsindo oklabalasayo ngenkathi ushayela. Lapho uthenga izingxenye zaseShayina ezisezingeni eliphansi, inkinga ivame ukuvela ngemuva kwezinyanga ezingama-2-3 zokusebenza.
Ukufakwa kwe-polyurethane bushings kanye namabhulokhi athule kuyafaneleka uma ukwanda kokuphathwa kwezimoto kuvela phambili, hhayi ukunethezeka komshayeli nabagibeli.
Indlela yokukhetha ingxenye
Lapho ukhetha izingxenye ze-polyurethane zokumiswa kwemoto, landela le mithetho:
- Thenga imiklamo kubakhiqizi abazinzile. Ziyikhwalithi ephezulu, nakuba zibiza kakhulu kunezinketho zaseShayina.
- Ungaxhumani nabathengisi abanikeza izingxenye ezisetshenzisiwe.
- Khetha ingxenye esitolo ukuze ukwazi ukuhlola ukuqhekeka, ukuklwebheka, nomunye umonakalo.
- Ungathengi kumasayithi akhangisiwe.
- I-block ethule kufanele ithengiswe ephaketheni eliqinile elinelebula elibonisa igama lengxenye, ikheli kanye nenombolo yocingo yomkhiqizi, i-imeyili noma eminye imininingwane yokuxhumana yokuxhumana, ukuhambisana nezindinganiso ze-GOST.
- Thenga kuphela lawo mabhulokhi athule lapho umenzi anikeza isiqinisekiso (imvamisa iminyaka engu-1-2, kungakhathaliseki ukuthi imayela elingakanani).
Qiniseka ukuthi ubheka isitifiketi sokuvumelana. Uma umdayisi enqaba ukunikeza idokhumenti ukuze ibuyekezwe, khona-ke unomgunyathi.
Indlela yokufaka ukumiswa kwe-polyurethane
Ngeke kwenzeke ukufaka ngokuzimela izingxenye ezenziwe nge-polyurethane. Ukuze wenze lokhu, udinga igumbi eline-flyover, umgodi noma i-lift kanye nemishini ekhethekile yokuhlakaza ukumiswa. Nikeza ongcweti umsebenzi ovela kusevisi yemoto.
