Indima yenduku yokuxhuma imoto.
Umsebenzi wenduku yokuxhuma ukuxhuma i-piston kanye ne-crankshaft, futhi udlulise amandla e-piston ku-crankshaft, futhi uguqule ukunyakaza okuphindaphindiwe kwe-piston ekunyakazeni okujikelezayo kwe-crankshaft.
Induku yokuxhuma imoto iyisici esibalulekile ngaphakathi enjinini, enesibopho sokuguqula ukunyakaza okuphindaphindayo kwepiston kube ukunyakaza okujikelezayo kwe-crankshaft. Le nqubo ayishintshi nje kuphela indlela yokunyakaza, kodwa futhi iguqula amandla afakwe ku-piston abe yi-torque ephumayo ye-crankshaft, eshayela amasondo emoto ukuba ajikeleze. Indima yenduku yokuxhuma ukuguqula ukushisa okukhiqizwa ukushiswa kukaphethiloli kube amandla omshini, bese kuba namandla okukhipha. I-automobile crank connecting rod mechanism iyingxenye enyakazayo yenjini, futhi umgomo wayo wokusebenza ukuguqula ukunyakaza okuphindaphindayo kwepiston kube ukunyakaza okujikelezayo kwe-crankshaft ngokusebenzisa induku yokuxhuma.
Umhlangano wenduku yokuxhuma uqukethe izinduku eziningi zokuxhuma ezihlanganiswe ndawonye ukuze zenze kangcono ukuzinza kwayo. Ixhuma i-piston kanye ne-crankshaft, bese idlulisela amandla akhishwa i-piston ku-crankshaft ukuze ibone ukuguqulwa ukusuka ekunyakazeni okuphindaphindayo kuya ekunyakazeni okuzungezisayo. Iqembu lenduku yokuxhuma lakhiwe ngomzimba wenduku yokuxhuma, induku yokuxhuma ikhava yekhanda elikhulu, induku yokuxhuma i-headhead bushing encane, induku yokuxhuma ikhanda elikhulu elithwele i-bushing kanye nebhawodi yenduku yokuxhuma (noma isikulufu), njll. Lezi zingxenye zisebenza ndawonye ukuze kuqinisekiswe ukusebenza kahle nokuzinza. yokudluliswa kwamandla ngaphakathi kwenjini.
Ngaphezu kwalokho, induku yokuxhuma nayo ithwala ukucindezela okukhiqizwa igesi yegumbi elivuthayo kanye namandla angenawo amandla e-longitudinal kanye naphambanayo, asebenza entongeni yokuxhuma lapho injini isebenza, edinga induku yokuxhuma ukuthi ibe namandla anele nokuqina ukuze ibhekane ne- umphumela wala mandla. Enqubweni yokushayela imoto, ukusebenza kwenduku yokuxhuma kuthinta ngqo ukusebenza kahle kwenjini kanye nokusebenza kokukhishwa kwamandla kwemoto yonke.
Iyini impahla yenduku yokuxhuma imoto?
I-Automobile connecting rod iyingxenye ebalulekile yenjini, futhi impahla yayo ngokuvamile iyinsimbi noma i-aluminium alloy. Phakathi kwazo, izixhumanisi zensimbi zivame kakhulu futhi zibiza kancane, kuyilapho izixhumanisi ze-aluminium alloy zilula futhi zihlala isikhathi eside kodwa zibiza kakhulu. Kodwa-ke, kwezinye izimoto zokugijima ezisezingeni eliphezulu kanye nezimoto ezinkulu, ukuze kwehliswe isisindo futhi kuthuthukiswe ukusebenza, i-carbon fiber noma ezinye izinto ezithuthukisiwe zingasetshenziswa ukwenza izinduku zokuxhuma. Ukusetshenziswa kwalezi zinto akukwazi nje ukuthuthukisa ukusebenza kwemoto, kodwa futhi kunciphise ukusetshenziswa kukaphethiloli nokukhishwa kwegesi, ngaleyo ndlela kuvikeleke kangcono imvelo.
Induku yokuxhuma ingenye yezingxenye ezigcizelelwe kakhulu enjini, ngakho-ke ukukhethwa kwezinto zayo kubaluleke kakhulu. Nakuba insimbi yokuxhuma inezindleko eziphansi, iyasinda futhi kulula ukuyikhubaza, okuthinta ukusebenza kwenjini. Induku yokuxhuma i-aluminium alloy inamandla angcono nokuqina, ingakwazi ukumelana nokucindezeleka okukhulu, futhi ngesikhathi esifanayo, ilula, ngaleyo ndlela ithuthukise amandla nokusebenza kahle kwenjini. Ngaphezu kwalokho, ukumelana nokugqwala kwezixhumanisi ze-aluminium nakho kungcono kunezixhumanisi zensimbi, futhi kungamelana kangcono nezinga lokushisa eliphezulu kanye nemvelo yokucindezela okuphezulu enjinini.
Ezimotweni zomjaho ezisezingeni eliphezulu nezinqola ezinkulu, ukusetshenziswa nje kwezinti zensimbi noma ze-aluminium ngeke kusahlangabezana nezimfuneko zazo. Lezi zimoto ngokuvamile zidinga ukuxhumana okulula, okuqinile ukuze zithuthukise ukusheshisa kwazo nokusebenza kokuphatha. Ngenxa yalokho, i-carbon fibre nezinye izinto ezithuthukisiwe ziyinketho ekhethwayo yalezi zimoto. Lezi zinto azigcini nje ngokuba namandla nokuqina okuphezulu, kodwa futhi zinokumelana nokugqwala okungcono nokumelana nokukhathala, futhi zikwazi kangcono ukuzivumelanisa nezimo zenjini enesivinini esikhulu kanye nomfutho ophezulu.
Ngamafuphi, ukukhethwa kwezinto ezibonakalayo kwenduku yokuxhuma imoto kubaluleke kakhulu, okuhlobene ngqo nokusebenza nokusebenza kahle kwenjini. Nakuba izixhumanisi zensimbi zibiza kancane, ezimotweni zomjaho ezisezingeni eliphezulu nezinkulu, izinto ezilula nezihlala isikhathi eside kufanele zisetshenziswe ukuthuthukisa ukusebenza kwazo. Izinduku zokuxhuma i-aluminium ziyisinqumo esihle, kuyilapho i-carbon fiber nezinye izinto ezithuthukisiwe zifaneleka kakhulu kulezi zimoto ezisebenza kahle.
