I-Genuine Original camshaft eyakhiwe ngezingxenye zemoto ye-cherry

I-camshaft adjuster iyi-valve yokulawula ukuphambuka kwe-cam, okuyi-valve ye-stroke ekhoneni, eyakhiwe i-activator kagesi ekhoneni kanye ne-eccentric hemispherical valve. I-actuator yamukela isakhiwo esihlanganisiwe, futhi i-actuator kagesi inesistimu ye-servo eyakhelwe ngaphakathi.

Isimiso: Shintsha isikhathi sokuvula sama-valve okungenisa nawokukhipha ngokuvumelana nezidingo zokusebenza zenjini. Uma injini ingaphansi komthwalo omkhulu, isilungisi se-camshaft sisetshenziselwa ukukhulisa i-engeli yokugqagqana kwe-valve ngokwejubane lenjini, ukuze kunikezwe umoya ohlanzekile omningi endaweni evuthayo ngangokunokwenzeka, ukuze kuzuzwe amandla aphezulu kanye ne-engeli egqagqene, ukuze kuhlinzekwe igumbi elivuthayo ngangokunokwenzeka Umoya omusha ukuze uzuze amandla aphezulu kanye netorque.

I-camshaft iyingxenye yenjini ye-piston. Umsebenzi wawo ukulawula ukuvulwa nokuvalwa kwama-valve. Nakuba ijubane le-camshaft enjinini ye-stroke emine liyingxenye ye-crankshaft (ijubane le-camshaft enjinini enama-stroke amabili liyafana nele-crankshaft), ngokuvamile ijubane layo lisephezulu kakhulu futhi lidinga ukuthwala i-torque enkulu. Ngakho-ke, umklamo unezidingo eziphakeme zamandla nokusekelwa kwendawo ye-camshaft, futhi impahla yayo ngokuvamile iyinsimbi ephezulu ye-alloy noma i-alloy steel. Ngenxa yokuthi umthetho wokunyakaza kwe-valve uhlobene namandla nezici zokusebenza zenjini, ukwakheka kwe-camshaft kudlala indima ebaluleke kakhulu enqubweni yokwakhiwa kwenjini.
Umzimba oyinhloko we-camshaft iyinduku ye-cylindrical cishe ngobude obufana ne-cylinder bank. Amakhamera amaningana anemikhono kuwo ukuze ashayele ivalvu. I-camshaft isekelwa emgodini ophethe i-camshaft ngokusebenzisa ijenali ye-camshaft, ngakho inani lamajenali e-camshaft liyisici esibalulekile esithinta ukuqina kokusekelwa kwe-camshaft. Uma ukuqina kwe-camshaft kunganele, ukuguqulwa kokugoba kuzokwenzeka ngesikhathi sokusebenza, okuthinta isikhathi se-valve.
Uhlangothi lwekamela lumise okweqanda. Iklanyelwe ukuqinisekisa ukungenisa okwanele kanye nokuphuma kwe-cylinder. Ngaphezu kwalokho, uma kucatshangelwa ukuqina nokusebenza kahle kwe-injini, i-valve ayikwazi ukuba nomthelela omkhulu ngenxa yenqubo yokusheshisa nokunciphisa izinga ekuvuleni nasekuvaleni isenzo, ngaphandle kwalokho kuzodala ukuguga okukhulu kwe-valve, ukwanda komsindo noma eminye imiphumela emibi. Ngakho-ke, ikhamera ihlobene ngokuqondile namandla, ukuphuma kwe-torque nokusebenza kahle kwenjini.
Amaphutha avamile e-camshaft ahlanganisa ukuguga okungavamile, umsindo ongavamile nokuphuka. Ukuguga okungavamile kuvame ukwenzeka ngaphambi komsindo ongavamile nokuphuka.
(1) I-camshaft isicishe ibe sekupheleni kwesistimu yokugcoba injini, ngakho-ke isimo sokuthambisa asinalo ithemba. Uma ingcindezi yokunikezwa kwamafutha ephampu kawoyela inganele ngenxa yesikhathi eside sesevisi, noma uwoyela wokugcoba awukwazi ukufinyelela ku-camshaft ngenxa yokuvinjelwa kwephaseji lamafutha okugcoba, noma uwoyela wokugcoba awukwazi ukungena ku-camshaft imvume ngenxa ye-torque eqinisiwe ngokweqile ye-bolts yokubopha ikhava yokuthwala, i-camshaft izobe igqoke i-abno.
(2) Ukuguga okungavamile kwe-camshaft kuzokwandisa igebe phakathi kwe-camshaft nesihlalo esinesihlalo, futhi i-camshaft izohamba nge-axially, kubangele umsindo ongavamile. Ukuguga okungavamile kuzophinde kwandise igebe phakathi kwekhamera yokushayela kanye ne-hydraulic tappet, futhi ikhamera izoshayisana ne-hydraulic tappet, kubangele umsindo ongajwayelekile.
(3) Ngezinye izikhathi kwenzeka amaphutha angathi sína njengokuphuka kwe-camshaft. Izimbangela ezivamile ukuhlukana kwe-tappet ye-hydraulic noma ukuguga okukhulu, ukugcotshwa okubi kakhulu, izinga eliphansi le-camshaft kanye nokuphuka kwegiya le-camshaft lesikhathi.
(4) Kwezinye izimo, ukwehluleka kwe-camshaft kubangelwa izici zomuntu, ikakhulukazi lapho i-camshaft ingahlakazwa ngendlela efanele ngesikhathi sokugcinwa kwenjini. Isibonelo, lapho ususa ikhava yokuthwala i-camshaft, yishaye ngesando noma uyikhiphe nge-screwdriver, noma ufake isembozo sokuthwala endaweni engafanele, okuholela ekungafanini phakathi kwesembozo sokuthwala kanye nesihlalo sokuthwala, noma i-torque eqinisayo ye-bolts yokubopha ikhava yokuthwala inkulu kakhulu. Lapho ufaka isembozo esithwalayo, naka umcibisholo wesiqondiso, inombolo yesikhundla kanye namanye amamaki ebusweni bekhava elithwalayo, futhi uqinise amabhawodi okubopha wekhava elithwala ngesikrufu se-torque ngokuhambisana ngokuqinile ne-torque eshiwo.
