Yiziphi ama-piston assemblies zemoto
I-automobile piston assembly ikakhulukazi ihlanganisa lezi zingxenye ezilandelayo: piston, piston ring, piston pin, connecting rod and connecting rod bear bush. Lezi zingxenye zisebenza ndawonye ukuze kuqinisekiswe ukusebenza kahle kwenjini.
I-piston iyingxenye yegumbi elivuthayo, imvamisa iba nemigqa eminingana yokufaka indandatho ye-piston, indima yayo eyinhloko ukuqondisa ukunyakaza okuphindaphindayo kusilinda futhi imelane nengcindezi eseceleni.
I-piston ring ifakwe ku-piston futhi idlala indima yokuvala. Ivamise ukwakhiwa ngendandatho yegesi kanye nendandatho kawoyela ukuze kuvinjwe izinga lokushisa eliphezulu kanye negesi yokucindezela okukhulu ukuthi ingangeni ku-crankcase futhi ivimbele uwoyela ukuthi ungangeni egunjini lomlilo .
Iphinikhodi ye-piston ixhuma ipiston nenduku yokuxhuma ikhanda elincane. Inezindlela ezimbili ezifanayo: ukuntanta okugcwele kanye nokuntanta uhhafu. Umsebenzi wayo ukudlulisa i-piston thrust ku-rod yokuxhuma.
Induku yokuxhuma i-piston ne-crankshaft, ihlukaniswe yaba ikhanda elikhulu nekhanda elincane, ikhanda elincane elixhuma ipiston, ikhanda elikhulu elixhuma i-crankshaft, indima yalo ukuguqula ukunyakaza okuhambisanayo kwepiston kube ukunyakaza okuzungezayo kwe-crankshaft.
Isihlahla esithwala induku yokuxhuma sifakwe ekugcineni okukhulu kwenduku yokuxhuma njengengxenye yokugcoba ukuze kuncishiswe ukungqubuzana phakathi kwenduku yokuxhuma ne-crankshaft nokuvikela injini.
Ukuhlanganiswa kwepiston kuyisici esibalulekile enjinini, ehlanganisa izingxenye eziningi, okuhlanganisa i-piston, iringi yepiston, iphinikhodi, induku yokuxhuma kanye nesihlahla esithwala induku. Umsebenzi oyinhloko wokuhlanganiswa kwepiston ukuguqula amandla amakhemikhali abe amandla okusebenza, ngokuphusha ingxube yamazinga okushisa aphezulu kanye negesi enomfutho omkhulu emgqonyeni, ukuze iphushe i-crankshaft ukuze ijikeleze futhi yenze injini isebenze.
Izingxenye ezithile kanye nemisebenzi yazo
ipiston : Ingxenye eyinhloko yegumbi elivuthayo, ipiston iphusha ingxube yamazinga okushisa aphezulu namagesi okucindezela kusilinda ukuze iphendule i-crankshaft futhi yenze injini isebenze.
indandatho ye-piston : isetshenziselwa ukuvala isilinda, ukuvimbela ukuvuza kwegesi, nokukhuhla uwoyela odongeni lwesilinda ukugcina udonga lwesilinda lugcotshiwe.
Iphinikhodi yepiston : Ixhuma ipiston nenduku yokuxhuma, idlulise amandla nokunyakaza.
induku yokuxhuma : iguqula ukunyakaza kwepiston kube ukunyakaza okujikelezayo kwe-crankshaft.
isihlahla esithwala induku yokuxhuma : I-shaft esekela induku yokuxhuma ukunciphisa ukungqubuzana nokuguga.
Idizayini ekhethekile - umhlangano wepiston ngomsebenzi wokugcoba osebenzayo
Imodeli yensiza ihlobene nokuhlangana kwepiston okusebenzayo kokuthambisa, okuhlanganisa ubuningi bamashidi entwasahlobo kanye nezihlalo zamandandatho ezinyo ezihlelwe phansi kwepiston. Lapho isebenza, ipuleti le-spring plate kanye nesihlalo sendandatho yezinyo kuyasebenzisana ukuze kujikelezwe, futhi kuletha amafutha awe ngokwemvelo engxenyeni engezansi yesilinda sebhuleki engxenyeni engenhla yesilinda sebhuleki, ukuze kubonakale ukujikeleza kwegrisi yesilinda sebhuleki ngaphakathi. i-cylinder yebhuleki futhi ufeze indima yokugcoba okusebenzayo.
