Yini intwasahlobo ye-car valve
I-Automobile Valve Spring iyingxenye ebalulekile yenjini yemoto, ephakathi kwekhanda lesilinda kanye ne-valve rod yomsila isihlalo sentwasahlobo. Umsebenzi wayo oyinhloko ukuqinisekisa ukuthi i-valve ihleli ngesikhathi futhi ifakwe ngokuqinile ukuvikela i-valve ekushayweni ngesikhathi sokudlidliza kwezinjini, ngaleyo ndlela ichithe ukubekwa uphawu kwayo.
Iziphethu ze-Valve zivame ukwenziwa ngekhwalithi ephezulu yensimbi yensimbi futhi kukhona ukushisa kwelashwa ukukhulisa amandla abo okukhathala. Ukuze uvikele ukugqwala kwentwasahlobo, ingaphezulu lizobe lihlelwe noma lihambisane. Iziphetho zalo ezimbili kufanele zibe yiflethi emhlabathini futhi zibe perpendicular ku-eksisi yasentwasahlobo ukuvikela i-skew ngesikhathi senqubo yokusebenza.
Idizayini nokukhethwa kwezinto ezibonakalayo kwe-valve entwasahlobo inomphumela obalulekile ekusebenzeni kwenjini. Ukuze ugweme ukuphikisana, izinjini zesimanje kakhulu usebenzisa iziphetho ze-pitch eziguqukayo noma ezifakwe kakhulu ezinhlamvu eziphindwe kabili. I-Double Spring Design ifaka iziphethu ezimbili eziphikisana nazo ngaphakathi nangaphandle. Ukuqina kwentwasahlobo yangaphandle kukhulu, okungavimbela ngempumelelo ukubonwa, futhi lapho enye intwasahlobo iphukile, enye ingaqhubeka nokusebenza ukuze kuqinisekiswe ukuvalwa okujwayelekile kwe-valve.
Umgomo osebenzayo we-Valve Spring ukuqinisekisa ukuthi i-valve ifakwe kakhulu esihlalweni se-valve ngokunqoba amandla aphezulu ngesikhathi senqubo yokuvala ye-valve futhi uvikele i-valve ekugxumeni ngaphansi komthwalo wokucindezela. Ngaphezu kwalokho, i-Valve Spring ingakwazi nokulawula ukunyakaza kwe-valve ukugwema ukuhlukaniswa kwe-valve mechanism.
Ngamafuphi, yize i-valve entwasahlobo incane enjini, indima yayo ibalulekile ukuqinisekisa ukusebenza okujwayelekile nokusebenza okuzinzile kwenjini.
Iqhaza eliphambili lemoto ye-Valve Spring lifaka phakathi izici ezilandelayo:
Qinisekisa isihlalo se-valve esifike ngesikhathi
Inqobe amandla angenakunqotshwa: Lapho i-valve ivuliwe, inqubo ye-valve izokhiqiza amandla angenzeka, i-valve entwasahlobo inganqoba la mabutho angeliyo ukuze aqinisekise ukuthi izingxenye zokuhambisa zihlala zilawulwa yi-cam futhi azihlukaniswe komunye nomunye.
Ukuvimbela ukuphikisana kanye ne-flutter: Ukuze kuvikeleke nge-valve spring resonance kwinqubo yokusebenza, ezinye izinjini zisebenzisa i-Double Valve Spring Isakhiwo, ukujikeleza okubili kwentwasahlobo okuphambene, kuthuthukisa ukudlidliza kwentwasahlobo entwasahlobo.
Amandla okukhathala athuthukisiwe kanye nokwethenjwa: iziphethu ze-valve zivame ukwenziwa ngekhwalithi ephezulu yensimbi yensimbi nokuphathwa ukushisa ukuze kuthuthukiswe ukumelana kwabo nokukhathala. Ukuvimbela ukugqwala, ingaphezulu lisegayiwe noma phosphating.
Hlela ukucindezelwa okunamandla okuphezulu nokusebenza okusheshayo: ngenjini kuya kumandla aphezulu, ukuthuthukiswa okusheshayo, iziphethu ze-valve zidinga ukumelana nengcindezi enamandla ashukumisayo nesivinini sokuphendula ngokushesha. Ngakho-ke, ukwakheka kanye nokwenziwa kwama-valve Springs adinga izidingo eziphakeme zobuchwepheshe.
