Iyini isiqondiso sesikhathi?
Isitimela sokuqondisa isikhathi siyingxenye ebalulekile yenjini yemoto, esetshenziswa kakhulu ukuqinisekisa ukusebenza okuzinzile kweketanga lesikhathi. Indima yeketanga lesikhathi ukudlulisela amandla egiya lesikhathi le-crankshaft kugiya lesikhathi le-camshaft, nokuqinisekisa ukuthi igiya lesikhathi le-crankshaft kanye negiya lesikhathi le-camshaft zinendawo efanele. Ngale ndlela, i-valve yokungenisa kanye ne-valve yokukhipha umoya yenjini kungavulwa noma kuvalwe ngesikhathi esifanele ukuqinisekisa ukuthi isilinda senjini singaphefumula futhi sikhiphe umoya ngendlela evamile. Umhlahlandlela wesikhathi usebenza kumhlahlandlela wokucindezela ngokusebenzisa i-tensioner, ngaleyo ndlela unikeze umphumela wokucindezela odingekayo ngesikhathi sokushayela kweketanga lesikhathi nokuqinisekisa ukusebenza okuzinzile kweketanga.
Ukwakheka kanye nokukhethwa kwezinto zomhlahlandlela wesikhathi kubalulekile ekusebenzeni nasekuthembekeni kwenjini. Ngokuvamile isetshenziswa ekudluliseni, ekuhambiseni imishini, ingenziwa ngezinto eziningana ezahlukene, ukukhetha okukhethekile kuncike ezidingweni zokusetshenziswa kanye nezimo zemvelo. Ukwakheka kanye nokugcinwa okufanele kwesitimela somhlahlandlela wesikhathi kubaluleke kakhulu ekwandiseni impilo yenjini, ukuthuthukisa ukusebenza kanye nokuqinisekisa ukuphepha kokushayela.
Kunenkinga nge-timing chain yenjini. Singaqhubeka yini?
Ukwehluleka kochungechunge lwesikhathi semoto kungathinta ulwazi lokushayela.
Kuzoba nokuguguleka phakathi kweketanga lesikhathi kanye ne-sprocket, ngakho-ke impilo yesevisi yeketanga lesikhathi inqunyelwe. Kodwa-ke, uma kuqhathaniswa nebhande lesikhathi, iketanga lesikhathi linokuphila isikhathi eside kwesevisi kanye nesilinganiso sokuhluleka esiphansi, ngakho ungaqhubeka nokushayela lapho iketanga lesikhathi likhala. Kodwa-ke, uma uwoyela wenjini ungashintshwa isikhathi eside noma ikhwalithi kawoyela ingalungile, kuzokwandisa ukuguguleka futhi kunciphise impilo yeketanga lesikhathi.
Ngisho noma impilo yeketanga lesikhathi ifinyelela ekupheleni, ngeke iphuke ngokushesha, kodwa izokhula kancane kancane. Umphumela wokwelula ungaba ukungazinzile kwevalvu, ukusheshisa kwenjini okubuthakathaka, noma ngisho nokwehluleka kwenjini ngenxa yokweqa amazinyo.
Ngakho-ke, uma uthola inkinga ngochungechunge lwesikhathi lwenjini yemoto, kufanele uhlole ngokushesha ukuthi uwoyela wokugcoba udinga ukushintshwa noma ukuthi udinga ukugcinwa usesimweni. Uma uwoyela wokugcoba ungashintshwa isikhathi eside noma ikhwalithi kawoyela ingalungile, kuzokwandisa ukuguguleka kochungechunge lwesikhathi futhi kufinyeze impilo. Uma impilo yochungechunge lwesikhathi iphela, injini ingaba nezinkinga ezifana nokungazinzi kanye nokungakwazi ukusheshisa. Ukuze ugweme lezi zinkinga, kunconywa ukuthi ushintshe uwoyela wokugcoba futhi uwugcine njalo ukuze wandise impilo yesevisi yochungechunge lwesikhathi.
Isikhathi sesitimela se-Timing chain ukuthi sizosishintsha isikhathi esingakanani
Kunconywa ukuthi kushintshwe ireyili yokuqondisa ngesikhathi lapho uchungechunge lwesikhathi luqhekeka, luphuka, luqhekeka amazinyo noma kwenzeka umsindo.
Okokuqala, indima yesitimela sokuqondisa uchungechunge lwesikhathi
Isitimela sokuqondisa uchungechunge lwesikhathi siyingxenye ebalulekile yochungechunge lwesikhathi oluthwala izimoto, imishini neminye imishini, indima yaso ukuqinisekisa indawo kanye nokuqina kochungechunge oluhambayo, ukugwema amazinyo okugxuma kweketanga noma ukuhamba okungafanele, ukuze kuqinisekiswe ukusebenza okuvamile kwemishini.
Okwesibili, impilo yenkonzo yesitimela somhlahlandlela weketanga
Isikhathi senkonzo yesitimela sokuqondisa uchungechunge lwesikhathi sihlobene nokusetshenziswa kwangempela, ukulungiswa kanye nezinye izici. Ngokuvamile, isikhathi sesitimela sochungechunge lwesikhathi side kakhulu, futhi ngaphansi kokusetshenziswa okuvamile, amashumi ezinkulungwane zamakhilomitha noma ngaphezulu kudingeka ashintshwe. Kodwa-ke, uma ukusetshenziswa kungagcinwanga kugcotshwa kahle, kuhlanzwa, kulungiswa, njll., noma kukhona ukuxokozela okukhulu nokudlidliza, isitimela sokuqondisa singase singonakaliswa, futhi isikhathi senkonzo sizofinyezwa ngokufanele.
Okwesithathu, nini ukufaka esikhundleni isitimela somhlahlandlela weketanga lesikhathi
Enkambisweni yokusebenzisa isitimela sokuqondisa se-timing chain, kungase kube nokuphuka, ukuxega, amazinyo agxumayo, umsindo nezinye izimo. Uma lezi zimo zenzeka, kuyadingeka ukushintsha isitimela sokuqondisa ngesikhathi ukuze kugwenywe ukwehluleka kwemishini futhi kuthinte ukusebenza okuvamile kanye nokuphepha kokusebenza kwemishini.
Okwesine, indlela yokufaka esikhundleni sesitimela somhlahlandlela we-timing chain
Uma ushintsha ireli yokuqondisa yeketanga lesikhathi, udinga ukulandela inqubo yokusebenza yobungcweti. Okokuqala, udinga ukuhlanza ireli yokuqondisa, bese usebenzisa amathuluzi ukususa ireli yokuqondisa endala, bese ufaka ireli yokuqondisa entsha. Okokugcina, udinga ukugcoba nokulungisa ireli yokuqondisa ukuqinisekisa ukuzinza nokunemba kweketanga elihambayo. Kufanele kukhunjuzwe ukuthi lapho ushintsha ireli yokuqondisa, kuyadingeka ukukhetha izesekeli zabakhiqizi abavamile, futhi ukusetshenziswa kwezesekeli mbumbulu nezingcolile akuvunyelwe ngokuphelele.
Sicela usishayele ucingo uma udinga usizoimikhiqizo ye-ch.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
