Enzani amabhande angaphambili enjinini?
Emuva "ezinsukwini zakudala", izinjini ezivuthayo zangaphakathi zazisebenzisa amabhande nama-pulley ukushayela izingxenye ezifana namaphampu amanzi noma amasistimu omoya. Yize ubuchwepheshe sebuthuthukile, amabhande aseyingxenye ebalulekile ezimotweni eziningi, amaloli namaSUV. Nakuba imoto ngayinye inesistimu yokushayela ibhande ehlukile eyenzelwe izinjini nokucushwa okuhlukene, ngokuvamile kunezinhlobo ezimbili zamabhande: izisekeli noma amabhande anezimbambo namabhande esikhathi.
Ibhande lezinsiza, elingaphambi kwenjini, liyingxenye ebalulekile elawula imisebenzi eminingi yemoto. Ingase futhi ibizwe ngebhande lenyoka, elizwakala lingaqondakali kakhulu kodwa lisho into efanayo. Isizathu segama layo ukuthi igoqa ama-pulley ahlukahlukene njengenyoka; yingakho igama elithi inyoka. Leli bhande lishayela izinto eziningana ezihambisanayo njengephampu yamanzi, ifeni yerediyetha, i-alternator kanye ne-air conditioning system.
Ibhande lesikhathi lifakwa ngaphansi kwekhava yenjini futhi liklanyelwe ukushayela i-crankshaft noma i-camshaft, elawula isikhathi sazo zonke izingxenye zenjini zangaphakathi njengama-piston nama-valve. Ngezinhloso zalesi sihloko, sizogxila ebhande lenyoka.
Lisebenza kanjani ibhande lenyoka
Leli bhande elilodwa lingena esikhundleni sesistimu yamabhande amaningi owake wasetshenziswa ezinjinini. Kumamodeli amadala, kwakukhona ibhande elilodwa lesesekeli ngasinye. Inkinga yayiwukuthi uma ibhande elilodwa ligqashuka, kwakudingeka ulikhumule wonke ukuze uvale elinye elingalungile. Akukona nje kuphela ukuthi lokhu kuthatha isikhathi, kodwa ngokuvamile kubiza abathengi imali eningi ukukhokhela umakhenikha ukwenza umsebenzi.
Ibhande lezinyoka laliklanyelwe ukuxazulula lezi zinkinga. Ibhande lenyoka noma insiza lilawula zonke lezi zingxenye. Iqhutshwa yi-crankshaft pulley futhi ingena futhi iphuma kuma-pulleys ehlukene esistimu yokusiza. Ezinye izimoto zingase zibe nebhande elizinikele lezesekeli ezithile, kodwa ezimweni eziningi ibhande elilodwa lenza imisebenzi eminingi. Lokhu kunciphisa inani lomsebenzi odingekayo ukuze kushintshwe ibhande eliphukile futhi kunciphisa ukudonsa kwenjini. Umphumela uwuhlelo olusebenza kahle kakhulu olugcina zonke izingxenye ezishayelwa ngamabhande zisebenza kahle.
Ibhande lenyoka lihlala isikhathi esingakanani?
Ibhande elinezimbambo ze-V lisetshenziswa njalo uma injini iqalwa, futhi lo msebenzi oqhubekayo uholela ekugugeni okukhulu. Njenganoma iyiphi enye ingxenye yerabha ethekwini lenjini, ichayeka emazingeni okushisa aphezulu futhi iguge ngokuhamba kwesikhathi. Impilo yesevisi yebhande lenyoka ikakhulukazi incike ohlotsheni lwempahla eyenziwe ngayo. Amabhande esitayela esidala ngokuvamile ahlala cishe amamayela angu-50,000, kuyilapho amabhande enziwe asuka ku-EPDM angahlala kufika kumamayela angu-100,000.
Inketho engcono kakhulu ukuthi imoto yakho inesevisi njalo futhi ibhande lihlolwe njalo lapho ushintsha uwoyela wenjini yakho nesihlungi. Kuyanconywa futhi ukuthi ibhande nama-pulleys kuhlolwe ngesikhathi sanoma yikuphi ukulungiswa kurediyetha noma uhlelo lokupholisa. Uma iphuka, uzothola ukuthi ulwazi lwakho lokushayela lushintshile. Ngaphandle kwaleli bhande, iphampu yakho yokuqondisa amandla ngeke isebenze, isistimu yakho yokupholisa umoya ngeke isebenze, futhi i-alternator yakho ngeke isebenze. Imoto nayo ingashisa kakhulu ngoba ipompo lamanzi ngeke lisebenze, okungase kulimaze injini ngokushesha.
Ngaso sonke isikhathi uma ushintsha ibhande le-V-ribbed, kunconywa ukuthi ushintshe ama-pulleys kanye ne-tensioner ngesikhathi esifanayo. Le sevisi kufanele yenziwe umakhenikha oqeqeshwe ngokomsebenzi, ngakho thinta umakhenikha wasendaweni yakini ukuze ubuyisele ibhande elinezimbambo ezingu-V njengoba kunconywe umenzi.
