Zvese nezve camshaft yeinjini

Injini camshaft

Zvekushanda kwakagadzikana kweinjini yemukati yemoto, imwe neimwe yenhengo dzayo inoita basa rakakosha. Pakati pavo pane camshaft. Funga nezve chii chiri basa rayo, zvikanganiso zvinoitika, uye mune zviitiko zvipi zvinoda kuchinjwa.

Chii chinonzi camshaft

Mune injini dzinopisa mukati dzine ina-stroke rudzi rwekushanda, camshaft chinhu chinokosha, pasina iyo mweya mutsva kana musanganiswa wemhepo-mafuta haizopindi mumasilinda. Iri ndiro shaft yakaiswa muhumburumbira musoro. Inodiwa kuitira kuti mavharuvhu ekutora uye ekupera azarure panguva yakakodzera.

Imwe neimwe camshaft ine makamera (kudonha-akaumbwa eccentrics) anodzvanya pane muteveri wepiston, achivhura gomba rinoenderana mukamuri yehumburumbira. Muchinyakare mana-stroke injini, camshafts anogara achishandiswa (panogona kuva maviri, mana kana imwe).

Ainoita

A drive pulley (kana asterisk, zvichienderana nerudzi rwenguva yekutyaira) inogadziriswa kubva kumagumo ecamshaft. Bhandi (kana cheni, kana asterisk yakaiswa) yakaiswa pairi, iyo yakabatana nepulley kana sprocket ye crankshaft. Munguva yekutenderera kwe crankshaft, torque inopihwa kune camshaft drive kuburikidza nebhandi kana cheni, nekuda kweiyo shaft iyi inotendeuka synchronously ne crankshaft.

Chikamu chemuchinjikwa che camshaft chinoratidza kuti makamu ari pairi akadonha-akaumbwa. Kana camshaft ikatendeuka, chikamu chakatambanudzwa checam chinosundidzira papipeti yevharuvhu, ichivhura chinopinda kana chekubuda. Kana mavharuvhu ekutora akavhurwa, mweya mutsva kana musanganiswa wemafuta emhepo unopinda mucylinder. Kana mavharuvhu ekupedza akavhurwa, gasi rinopera rinobviswa kubva muhumburumbira.

Iyo dhizaini yecamshaft inobvumidza iwe kugara uchivhura / kuvhara mavharuvhu panguva chaiyo, kuve nechokwadi chekugovera gasi rakakwana mujini. Nokudaro, chikamu ichi chinonzi camshaft. Kana iyo shaft torque ichichinjika (somuenzaniso, kana bhandi kana ketani yakatambanudzwa), mavharuvhu haavhurike maererano nekurohwa kunoitwa muhumburumbira, izvo zvinotungamira mukusagadzikana kushanda kweinjini yekupisa kwemukati kana kusabvumira kuti iite. shanda zvachose.

Iko camshaft iri kupi?

Iko kune camshaft kunoenderana nemagadzirirwo maficha emota. Mune kumwe kunatsurudzwa, iri pazasi, pasi pesirinda block. Kugadziridzwa kweinjini kwakajairika, iyo camshaft iyo iri mumusoro we cylinder (pamusoro peinjini yekutsva yemukati). Muchiitiko chechipiri, kugadzirisa uye kugadzirisa kweiyo gasi yekuparadzira michina iri nyore kwazvo pane yekutanga.

Nadzurudzo dzeV-dzakagadzirwa injini dzakashongedzerwa nebhanhire renguva, iro riri mukudonha kweye cylinder block, uye dzimwe nguva bhuroko rakapatsanurwa riine gasi rayo rekuparadzira mashandiro. Iyo camshaft pachayo inogadziriswa mudzimba ine mabheyaringi, ayo anoitendera kuti itenderere nguva dzose uye zvakanaka. Mune engines boxer (kana boxer), dhizaini yemukati injini yemoto haibvumidze kuiswa kweimwe camshaft. Mune ino kesi, yakasarudzika gasi yekuparadzira mashandiro akaisirwa padivi rega, asi basa ravo rakawiriraniswa.

Camshaft inoshanda

Iyo camshaft chinhu cheiyo nguva (gasi yekuparadzira mashandiro). Iyo inosarudzira marongero einjini sitiroko uye inowirirana kuvhura / kuvhara kwemavharuvhu ayo anopa mweya-mafuta musanganiswa kumasirinda uye kubvisa mweya wekupedza.

Iyo yekuparadzira gasi mashandiro inoshanda zvinoenderana nesimboti inotevera. Panguva iyo injini painotanga, iyo starter crank cranksmugodhi... Iyo camshaft inotyairwa neketani, bhanhire pamusoro pe crankshaft pulley, kana magiya (mune dzakawanda mota dzekare dzeAmerica). Vheji yekudya iri musilinda inovhura uye musanganiswa wepeturu nemhepo zvinopinda mukamuri yemoto. Panguva imwecheteyo, iyo crankshaft sensor inotumira kurovera kune iyo kuvesa coil. Kusunungurwa kunogadzirwa mairi, kunoenda ku spark plug.

Pakazosvika nguva yekupenya, mavharuvhu ese ari musilinda akavharwa uye musanganiswa wemafuta unotsikirirwa. Munguva yemoto, simba rinogadzirwa uye iyo pisitoni inodzikira pasi. Aya ndiwo mabatiro anoita crankshaft uye anotyaira iyo camshaft. Panguva ino, anovhura vharuvhu yekupedza iyo magasi aneta panguva yemagetsi anoburitswa.

Iyo camshaft inogara ichivhura iyo chaiyo vharuvhu kune yakatarwa nguva uye kune yakajairwa kukwirira. Nekuda kwechimiro chayo, chinhu ichi chinopa kutenderera kwakadzikama kwekutenderera kwemhepo mune mota.

Tsanangudzo pane zvikamu zvekuvhura nekuvhara mavharuvhu, pamwe nezvirongwa zvavo, zvinoratidzwa muvhidhiyo iyi:

Zvikamu pane camshafts, ndezvipi zvinowirirana zvinofanirwa kuiswa? Chii chinonzi "camshaft phase"?

Zvichienderana neshanduro yeinjini, inogona kunge iri imwe kana yakawanda camshafts. Mumota zhinji, chikamu ichi chiri mumusoro we cylinder. Inotyairwa nekutenderera kweye crankshaft. Zvinhu zviviri izvi zvakasunganidzwa nebhanhire, cheni yenguva kana giya chitima.

Kakawanda, camshaft imwe ine injini yemoto yemukati ine-mukati-masirinda. Mazhinji emainjini aya ane mavhavha maviri pasirinda (imwe yekupinda uye imwe nzira). Iko kune zvakare kugadziridzwa ine matatu mavhavha pasirinda (maviri einlet, imwe yekubuda). Injini ine mavhavha mana pasirinda anowanzo kuve akashongedzerwa nemiseve miviri. Mumakinjini anopisa anopisa uye aine V-chimiro, maviri camshafts akaiswawo.

Motors ine imwechete nguva shaft ine dhizaini yakapusa, iyo inotungamira mukudzikira kwemutengo weyuniti panguva yekugadzira. Izvi zvigadziriso zviri nyore kuchengetedza. Ivo vanogara vakaiswa pamabhajeti mota.

Pane anodhura enjini kugadziridzwa, vamwe vagadziri vanoisa yechipiri camshaft yekudzora mutoro (uchienzaniswa nesarudzo yenguva neyeimwe shaft) uye mune mamwe maICE modhi kupa shanduko muzvikamu zvekuparadzira gasi. Kazhinji kazhinji, yakadaro sisitimu inowanikwa mumota dzinofanirwa kuve dzemitambo.

Iyo camshaft inogara ichivhura vharuvhu kune yakatarwa nguva yenguva. Kuti uvandudze kushanda kwemotokari padanho repamusoro, ichi chinguva chinofanira kuchinjwa (injini inoda mweya yakawanda). Asi nemamiriro akajairwa eiyo nzira yekuparadzira gasi, paakawedzera crankshaft kumhanya, iyo vheji yekuvhara inovhara pasati huwandu hunodiwa hwemhepo hwapinda mukamuri.

Panguva imwecheteyo, kana iwe ukaisa yemitambo camshaft (iyo cams inovhura mavharuvhu ekudyiwa kwenguva yakareba uye pakukwirira kwakasiyana), pakumhanya kweinjini, pane mukana wakakura wekuti vheji yekudyara ichavhura kunyangwe iyo vharuvhu yekuvhara isati yavhara. Nekuda kweizvi, mamwe emusanganiswa anozopinda mune yekudzimisa system. Mhedzisiro yacho kurasikirwa kwesimba pakumhanya kwakaderera uye kuwedzera kwekubuda.

Iyo yakapusa zano yekuzadzisa izvi kuita kuisa cranking camshaft pane imwe kona inoenderana necrankshaft. Iyi michina inobvumidza kutanga uye kunonoka kuvhara / kuvhura kweanotora uye ekupedza mavharuvhu. Pa rpm kusvika ku 3500, ichave iri munzvimbo imwechete, uye kana chikumbaridzo ichi chikakundwa, shaft inotendeuka zvishoma.

Imwe neimwe inogadzira inogonesa mota dzayo neiyi sisitimu inoratidza kumaka kwayo muzvinyorwa zvehunyanzvi. Semuenzaniso, Honda inotsanangura VTEC kana i-VTEC, Hyundai inotsanangura CVVT, Fiat - MultiAir, Mazda - S-VT, BMW - VANOS, Audi - Valvelift, Volkswagen - VVT, nezvimwe.

Parizvino, kuitira kuti kuwedzere kushanda kwemasimba emagetsi, magetsi emagetsi uye pneumatic asina gasi ekuparadzira gadziriro ari kugadzirwa. Nepo kugadziriswa kwakadai kuchidhura kwazvo kugadzira nekuchengetedza, saka haasati aiswa pamotokari dzekugadzira.

Kunze kwekuparadzanisa sitiroko dzeinjini, chikamu ichi chinotyaira zvimwe zvekushandisa (zvinoenderana nekushandurwa kwemota), semuenzaniso, mapampu emafuta nemafuta, pamwe neyagovana shaft.

Camshaft dhizaini

Camshafts inogadzirwa nekugadzira, kukanda kwakasimba, kukanda mhango, uye munguva pfupi yapfuura pakave nekugadziriswa kwetsvina. Chinangwa chekushandura tekinoroji yekugadzira ndeyekurerutsa chimiro kuti chiwane kushanda kwakanyanya kwemota.

Iyo camshaft inogadzirwa nenzira yeshamhu, pane izvo zvinotevera zvinhu:

• Sock. Uku ndiko kumberi kwe shaft uko kunoitwa kiyi. Iyo nguva pulley yakaiswa pano. Muchiitiko checheni yekutyaira, asterisk yakaiswa munzvimbo yayo. Ichi chikamu chakagadziriswa kubva kumagumo nebhaudhi.
• Omentum mutsipa. Chisimbiso chemafuta chakanamatirwa pairi kudzivirira mafuta kubva mukubuda munzira.
• Tsigira mutsipa. Huwandu hwezvinhu zvakadaro zvinoenderana nehurefu hwetsvimbo. Kutsigira mabheyari akaisirwa pavari, ayo anoderedza kukakavara panguva yekutenderera kwetsvimbo. Zvinhu izvi zvakaiswa mune inoenderana grooves mune humburumbira musoro.
