Iyadlula… izizukulwane

Njengoba wazi, iningi lezinhlobo zezimoto ezithandwayo ezikhiqizwa namuhla ziyi-front-wheel drive. Ngakho-ke, ukwenza isinqumo esinjalo kufanele kuholele ekusetshenzisweni komhlangano oqinile oqinile wamasondo okukhwelana. Ngenxa yamandla amakhulu asebenza emasondweni ngesikhathi sokunyakaza, okubizwa ngokuthi ama-angular contact ball bearings avela. Njengamanje, isizukulwane sabo sesithathu sesivele sifakwe ezimotweni, kungakhathaliseki ukuthi ubukhulu nenjongo yale modeli yemoto.

Ekuqaleni kwakukhona amaphutha ...

Akubona bonke abathanda izimoto abaziyo ukuthi ama-steel ball bearings bekungaqali ukusetshenziswa ezimotweni, ngaphambi kokufika kwezimoto ezidonsa ngamasondo angaphambili, bekugcwele uhlobo olungasebenzi kakhulu lwama-roller bearings. Naphezu kokulula komklamo wayo, yayinezihibe ezimbalwa ezibalulekile. Ububi obukhulu kanye nokuphazamiseka okukhulu kwama-roller bearings kwaba isidingo sokulungiswa ngezikhathi ezithile kokucaciswa kwe-axial nokugcotshwa kwawo. Lokhu kushiyeka akusekho kuma-angular amabhola okuxhumana wesimanje. Ngaphezu kokuthi azikhokhwa nhlobo, futhi ahlala isikhathi eside kakhulu kune-conical.

Inkinobho noma (okugcwele) uxhumano

Isizukulwane sesithathu se-double-row angular contact ball bearings singatholakala ezimotweni ezikhiqizwa namuhla. Uma kuqhathaniswa neyangaphambili, bathuthuke kakhulu kwezobuchwepheshe, futhi ngaphezu kwakho konke, umsebenzi wabo usekelwe kusixazululo esihlukile sobuchwepheshe esihambisana nomhlangano wabo. Ngakho lezi zizukulwane zihluke kanjani komunye nomunye? Amabhola amabhola amabili alula wokuxhumana we-angular esizukulwane sokuqala afakwe kulokho okubizwa ngokuthi "Push" esihlalweni se-crossover. Ngokulandelayo, ama-bearings esizukulwane sesibili athuthuke kakhulu ahlukaniswa ngokuhlanganiswa kwawo nehabhu lamasondo. Esizukulwaneni sesithathu esithuthuke kakhulu kwezobuchwepheshe, amabhereli ebhola e-angular axhumene nemigqa emibili asebenza ekuxhumaneni okungenakuhlukaniswa phakathi kwehabhu nequnu lokuqondisa. Ama-bearings esizukulwane sokuqala angatholakala ikakhulukazi kumamodeli ezimoto amadala, kuhlanganisa. Opel Kadett futhi Astra I, owesibili, isibonelo, "Nissan Primera". Ngakolunye uhlangothi, isizukulwane sesithathu se-double-row angular ball bearings singatholakala - okungenzeka, mhlawumbe, sizomangaza abaningi - ku-Fiat Panda encane kanye ne-Ford Mondeo.

Pitting, kodwa hhayi kuphela

Ngokusho kochwepheshe, ama-double-row angular contact ball bearings ahlala isikhathi eside kakhulu: kwanele ukusho ukuthi ngokombono wezobuchwepheshe, kufanele aqhubeke iminyaka engu-15 yokusebenza. Lokhu kuningi, kodwa, ngeshwa, ezimweni eziningi kuphela ngombono. Kungani ukuzijwayeza kubonisa okuhlukile? Phakathi kwezinye izinto, impilo yesevisi yama-wheel bearings iyancipha. ukuguga okuqhubekayo kwezinto ezenziwe ngazo. Ngolimi lochwepheshe, lesi simo sibizwa ngokuthi i-pitting. Ama-angular amabhola okuxhumana amarowu amabili nawo awafaki isandla ekungeneni kwezinhlobo ezahlukene zokungcola. Lokhu kuthinta umonakalo oqhubekayo ku-wheel hub seal. Ngakolunye uhlangothi, i-squeak eside yamasondo angaphambili ingase ibonise ukuthi ukuthwala kuthinteka ukugqwala, okuthe, ngaphezu kwalokho, kungene ngokujulile ngaphakathi kwayo. Olunye uphawu lwelinye lama-bearings angasebenzi kahle wukuvevezela kwesondo, bese lidlulela kuso sonke isiteringi semoto. Singabheka kalula ukuthi yini eyonakele. Ukuze wenze lokhu, phakamisa imoto ku-lift bese uhambisa amasondo angaphambili ohlangothini oluphambene futhi uhambisane ne-eksisi yawo yokujikeleza.

Ukushintshwa, okungukuthi, ukuminyanisa noma ukuqaqa

Ibhodi elimele, kungakhathaliseki ukuthi isizukulwane sini, lingashintshwa kalula uma kuqhathaniswa. Endabeni yezinhlobo zezixazululo ezindala, isb. isizukulwane sokuqala, i-bearing eyonakele iyashintshwa futhi ifakwe esimweni esihle ngokuyicindezela ngomshini wokunyathelisa we-hydraulic manual. Kulula nakakhulu ukwenza lokhu esimweni sokuthwala uhlobo lokugcina, i.e. isizukulwane sesithathu. Ukuze wenze okushintshwayo okulungile, vele ukhulule bese uqinisa izikulufu ezimbalwa. Sicela uqaphele, nokho, khumbula ukuwaqinisa ku-torque efanele usebenzisa isikrufu se-torque.
