Izimpawu zejoyinti le-Universal elinephutha noma elihlulekayo (i-U-joint)

Izimpawu ezijwayelekile zejoyinti lendawo yonke ehlulekayo zihlanganisa umsindo oklabalasayo, ukuklabalasa lapho ushintsha amagiya, ukudlidliza emotweni, nokuvuza koketshezi oludluliselayo.

Amajoyinti e-Universal (afushaniswe ngokuthi ama-U-joints) ayizingxenye zokuhlanganisa i-driveshaft ezitholakala emalolini amaningi adonsa ngamasondo angemuva, amaloli angu-XNUMXWD nama-SUV, kanye nama-SUV. Amalungu e-Cardan, akhiwe ngababili ku-driveshaft, ahlawulela ukungahambi kahle ekuphakameni phakathi kokudlulisa kanye ne-axle yangemuva, ngenkathi ehambisa amandla okuhambisa imoto. Lokhu kuvumela isiphetho ngasinye se-driveshaft kanye nokuhlangana kwayo kwendawo yonke okuhlotshaniswa nayo ukuthi kugobe ngokuzungezisa ngakunye kwe-driveshaft ukubhekana nokungahambi kahle (njengoba kunjalo, izimoto ezishayela ngamasondo angemuva kulezi zinsuku zisebenzisa amajoyinti esivinini esingaguquki ngenjongo efanayo, okuvumela ukuguquguquka okushelelayo. drive shaft rotation).

Nazi ezinye izimpawu zejoyinti lendawo yonke elibi noma elingasebenzi kahle ongase uluqaphele, ngohlelo olunzima lokuqina:

1. Ukunyakaza ekuqaleni kokunyakaza (kuya phambili noma emuva)

Izingxenye ezithwalayo zejoyinti ngalinye le-universal zigcotshwa efekthri, kodwa zingase zingabi nayo igrisi yokufaka ukugcoba okwengeziwe ngemva kokuba imoto isifakwe emsebenzini, okukhawulela ukuphila kwazo. Njengoba ingxenye ethwele yejoyinti ngalinye lendawo yonke iphenduka kancane ngokuzungezisa ngakunye kwe-drive shaft (kodwa njalo isendaweni efanayo), amafutha angahwamuka noma akhishwe enkomishini yokuthwala. Ukuthwala kuba okomile, ukuthintana kwensimbi-kuya-metal kwenzeka, futhi ama-joint bearings jikelele azokhala njengoba i-shaft yokushayela ijikeleza. I-squeak ngokuvamile ayizwakali lapho imoto ihamba ngokushesha kune-5-10 mph ngenxa yeminye imisindo yemoto. I-squeak iyisexwayiso sokuthi i-universal joint kufanele isetshenziswe umakhenikha ochwepheshe. Ngale ndlela, ungakwazi ngokuqinisekile ukunweba impilo yamalunga akho wendawo yonke.

2. "Qoqa" ngokukhala lapho ushintsha ukusuka kuDrayivu ukuya ku-Reverse.

Lo msindo uvamise ukukhombisa ukuthi amabheringi ahlangene nendawo yonke anemvume eyanele yokuthi i-driveshaft ingakwazi ukuzungeza kancane bese ima kungazelelwe lapho ishintsha amandla. Lokhu kungaba yisigaba esilandelayo sokugqoka ngemuva kokugcoba okunganele kuma-joint bearings jikelele. Ukusevisa noma ukugcoba ama-gimbal bearings ngeke kulungise umonakalo ku-gimbal, kodwa kungase kwandise impilo yegimbal kancane.

3. Ukudlidliza kuzwakala kuyo yonke imoto lapho iya phambili ngesivinini.

Lokhu kudlidliza kusho ukuthi ama-gimbal bearings manje aseguge ngokwanele ukuze i-gimbal ihambe ngaphandle kwendlela yayo evamile yokuzungeza, okubangela ukungalingani nokudlidliza. Lokhu kuzoba ukudlidliza kwemvamisa ephakeme kune, ngokwesibonelo, isondo elingalingani, njengoba i-propeller shaft ijikeleza izikhathi ezi-3-4 ngokushesha kunamasondo. Ijoyinti le-universal eligugile manje lidala ukulimala kwezinye izingxenye zemoto, okuhlanganisa nokudluliselwa. Ukushintshwa kwejoyinti lendawo yonke kufakwe umakhenikha ochwepheshile ngokuqinisekile kuhloselwe ukuvimbela ukulimala okwengeziwe. Umakhenikha wakho kufanele, noma nini lapho kunokwenzeka, akhethe amajoyinti e-universal ashintshwayo ekhwalithi afakwe igrisi ukuvumela ukugcinwa kokuvimbela isikhathi eside futhi andise impilo yamabheringi ahlangene wonke.

4. Uketshezi oludlulisayo luyavuza ngemuva kokudlulisela.

Ukuvuza koketshezi oludlulisayo oluvela ngemuva kokudlulisela kuvame ukuba umphumela wejoyinti eligugile kabi elisendaweni yonke. Ukudlidliza okungenhla kubangele ukuthi i-transmission shaft bushing yangemuva iguge futhi ilimale ku-transmission output shaft seal, okwabe sekuvuza uketshezi lokudlulisela. Uma kusolwa ukuvuza koketshezi oludlulisayo, ukudluliselwa kufanele kuhlolwe ukuze kutholwe umthombo wokuvuza futhi kulungiswe ngokufanele.

5. Imoto ayikwazi ukuhamba ngaphansi kwamandla ayo; i-propeller shaft isusiwe

Cishe wake wakubona lokhu ngaphambilini: iloli eceleni komgwaqo eline-shaft yokushayela ilele ngaphansi kwemoto, alisaxhunywanga ku-transmission noma i-asi yangemuva. Lesi yisimo esibi kakhulu sokwehluleka kwe-gimbal - iphuka ngokoqobo futhi ivumele i-drive shaft ukuthi iwele endaweni egandayiwe, ingasadlulisi amandla. Ukulungisa kuleli qophelo kuzobandakanya okungaphezulu kakhulu kokuhlangana kwendawo yonke futhi kungase kudinge ukushintshwa kwe-shaft ephelele noma ngaphezulu.
