Injini dzakawanda dzemazuva ano dzichiri kushandisa gasi kugovera zvirongwa zvine mavharuvhu madhiraivha uchishandisa rocker maoko.Rocker maoko akaiswa pane yakakosha chikamu - iyo axis.Verenga nezve iyo rocker arm axis, kuti inoshanda uye inoshanda sei, pamwe nekusarudzwa kwayo uye kutsiva mune chinyorwa.
Chii chinonzi rocker arm axis?
Iyo rocker arm axis chikamu chegasi rekugovera nzira yekudzoreredza injini dzinopisa dzemukati dzine mavharuvhu epamusoro;Irod ine buri inobata maoko e rocker emavharuvhu uye zvikamu zvine hukama zvemagetsi evharuvhu.
Iyo rocker arm axis inoita mabasa akati wandei:
• Kumira zvakanaka kwemaoko e rocker maererano necamshaft tappets/cams nemavharuvhu;
• Kuzora kwenzvimbo dzekukwenya kwemaoko e rocker uye mabearings avo, kupihwa kwemafuta kune zvimwe zvinhu zvegasi rekugovera mashandiro;
• Kuchengetwa kwemaoko e rocker, zvitubu zvavo uye zvimwe zvikamu (axle inoshanda sechinhu chinotakura simba).
Ndokunge, rocker arm axis ndiyo huru-inotakura chinhu kune akati wandei ezvikamu zvenguva (rocker maoko, zvitubu uye zvimwe) uye imwe yemitsetse yemafuta eiyo yakabatana injini lubrication system.Ichi chikamu chinoshandiswa chete pamusoro peinjini dzevharuvhu ine nguva yevhavha drive yemhando dzakasiyana siyana:
- Iine camshaft yakaderera, ine actuation yemavharuvhu kuburikidza nematepi, tsvimbo uye rocker maoko;
- Iine camshaft yepamusoro (yakajairwa kana yakaparadzana shaft yemutsara wega wega mavharuvhu), ine actuation yemavharuvhu kuburikidza nemaoko e rocker;
- Iine camshaft iri pamusoro, ine mavharuvhu anofambiswa kuburikidza nelever pusher.
Mune injini dzemazuva ano ine yakananga valve drive kubva kucamshaft cams, rocker maoko uye zvikamu zvine hukama hazvipo.
Iyo rocker arm axis inoita basa rakakosha mukushanda kweinjini, kuve nechokwadi chekushanda kwakajairwa kwevhavha yayo yenguva.Axle yakashata kana yakaremara inoda kutsiviwa nekukurumidza sezvinobvira, uye kuti uite sarudzo yakanaka yeichi chikamu, unofanirwa kunzwisisa aripo marudzi emaekisi, magadzirirwo awo uye maitiro.
Ndokumbira utarise: nhasi mumabhuku uye mabhizinesi ekutengesa, izwi rekuti "rocker arm axis" rinoshandiswa mune zviviri zvirevo - sechikamu chakaparadzana, gomba chubhu inobatwa maoko e rocker, zvitubu uye zvimwe zvikamu, uye seyero yakazara ine. zvakatoiswa zvinotsigira, rocker maoko uye zvitubu.Mune ramangwana, isu tichataura nezve masanhu e rocker maoko mune ese maviri aya pfungwa.
Mhando, dhizaini uye kumisikidzwa kwe rocker arm axes
Axles akakamurwa kuita akati wandei mhando zvichienderana nehuwandu hwemaoko e rocker akaiswa uye zvinoenderana nemamwe magadzirirwo maficha.
Zvinoenderana nehuwandu hweakaiswa rocker maoko, ma axles ndeaya:
• Solo;
• Boka.
Ekisero yega yega chikamu chinotakura ruoko rumwe chete rwe rocker uye fasteners (thrust washer kana nut).Mumwe nomumwe rocker arm axles anoshandiswa, sekutonga, mumajini ane mavharuvhu maviri pa cylinder, saka nhamba yeaxles mairi inopeta kaviri semasilinda.Axis yakadaro inogadzirwa panguva imwe chete ne rack, saka inosungirirwa pamusoro we cylinder pasina zvimwe zvikamu, chimiro chose chiri nyore uye chakareruka.Nekudaro, iyo axis yega yega yemaoko e rocker haigone kugadziriswa kana paine kusashanda, inongoshandura gungano.
Axle ine rocker arm assembly
Axle yeboka chikamu chinotakura maoko e rocker akati wandei uye zvikamu zvinoenderana (zvitubu, thrust washers, pini).Kubva pa2 kusvika ku12 maoko e rocker anogona kuwanikwa pane imwe axle, zvichienderana nekugadzirwa kweinjini uye nhamba yemasilinda.Saka, painjini dzine misoro yakasiyana-siyana, maekisi ane maoko maviri e rocker anoshandiswa kune imwe silinda, pane mamwe 6-cylinder injini dzine misoro yakasiyana-cylinder yemasilinda matatu, maekisi maviri ane maoko matanhatu e rocker anoshandiswa pamutsetse 4, 5 uye. 6-cylinder injini, maekisi ane 8, 10 uye 12 rocker maoko, zvichiteerana, etc. Nhamba yeboka re rocker maoko mune imwe in-line kana V-yakaita injini ine imwechete cylinder musoro wenhamba yemasilinda inogona kuva 1, 2 kana 4. Midziyo ine mavharuvhu maviri pahumburumbira inoshandisa imwe kana maviri ekisi (munyaya yemusoro wakasiyana wecylinder), mota dzine mavharuvhu mana pacylinder dzinoshandisa maviri kana mana ekisi.Huwandu hwemaekisi muinjini dzine misoro yehumburumbira inoenderana nenhamba yemisoro.
Matemo eboka emaoko e rocker ari nyore.Iwo akavakirwa pane axis pachayo - simbi shaft ine kuburikidza nelongitudinal chiteshi uye akati wandei maburi anochinjika zvichienderana nehuwandu hwemaoko e rocker akaiswa.Iyo yakanyanyisa maburi maburi anowanzo shandiswa kugadzirisa ekisi mumaraki ane cotter pini uye thrust washers.Sezvo ekisi iri pasi pemitoro yakakwira, inogadzirwa nemagiredhi akakosha esimbi, uye pamusoro payo inowedzera pasi pemakemikari-thermal uye kupisa kurapwa (carburization, kuoma) kuwedzera simba, kuramba kupfeka uye zvimwe zvinokanganisa.
Maoko eRocker akaiswa paekisi kuburikidza nemakwenzi (plain bearings yakagadzirwa nebronze kana zvimwe zvinhu), mikoto nemigero inogadzirwa mumakwenzi ekugovera mafuta kubva muekisi kuenda kumaoko e rocker.Peya dzemaoko e rocker dzakamisikidzwa ne spacer cylindrical springs inopfekwa pa ekisi.Iyo axle yakaiswa pamusoro wecylinder uchishandisa akateedzana racks - maviri akanyanyisa uye akati wandei makuru (pakati) ari pakati pemaoko e rocker.Iyo axle inogona kuiswa mune racks zvakasununguka kana kudzvanywa mavari.Iyo rocker arm axles ye ina-vharuvhu injini inogona kuiswa pamapatya struts, ayo anovimbisa kumira kwakaringana kwezvikamu zvenguva.Pamusoro penzvimbo dzezasi dzema racks pane mapini epakati uye maburi ezvitubu / mabhaudhi ekusimbisa.
Mafuta anopihwa kune rocker arm axle anogona kuitwa nenzira mbiri:
• Kuburikidza neimwe rack;
• Kuburikidza nechubhu yekugovera yakasiyana.
Muchiitiko chekutanga, imwe yeakanyanya kana yepakati struts ine chiteshi mairi mafuta anoyerera kubva kune inoenderana cylinder musoro chiteshi kuenda kune rocker arm axis.Muchiitiko chechipiri, chubhu yesimbi yakabatana kune chiteshi chemafuta mumusoro wecylinder inopihwa kubva kune imwe mugumo kusvika kune axis yemaoko e rocker.
Kazhinji, ma axles emaoko e rocker emarudzi ese ane dhizaini iri nyore, uye saka yakavimbika uye yakasimba, kunyangwe zvikamu izvi zvinogona kutadza - mune iyi kesi, zvinoda kugadziriswa kana kutsiviwa.
Dhizaini yerocker arm axis ine mafuta anopihwa kuburikidza nembiru yepakati
Nyaya dzekusarudza, kugadzirisa uye kutsiva rocker arm axes
Kufanana nezvimwe zvakawanda zvikamu, rocker arm axes anowanzo kugadzirwa ega kune yakasarudzika modhi renji kana kunyange injini shanduko, iyo inomisa zvirambidzo pasarudzo yezvikamu izvi.Naizvozvo, pakutsiva, zvinodikanwa kuti usarudze chete iwo maekisi anokurudzirwa neanogadzira injini pachayo - saka pane vimbiso yekuti zvikamu zvitsva zvichawira munzvimbo uye kushanda zvakajairika.
Neparutivi, zvinofanirwa kucherechedzwa kuti kunyangwe shanduko dzakasiyana dzeimwe mota dzinowanzo shongedzerwa ne rocker arm axes akasiyana mukugadzira uye maitiro.Semuenzaniso, mamwe masimba emagetsi emumba e peturu yemhando dzakasiyana ane cylinder misoro isina kufanana mukugadzira uye zviyero, saka, avo rocker arm axes anogona kusiyana (akashongedzerwa racks ehurefu hwakasiyana, rocker maoko, nezvimwewo).Izvi zvinofanirwa kuverengerwa kana uchitenga spare parts nekugadzirisa.
Iyo rocker arm axle inofanirwa kubviswa uye kuiswa chete zvinoenderana nemirairo yekugadzirisa nekugadzirisa mota.Icho chokwadi ndechekuti kune yakajairika kushanda kweakisi uye kudzivirira kwekuputsika, zvisungo zvayo (mabhaudhi kana ma stud nuts) zvinofanirwa kusimbiswa mukutevedzana kwakaringana uye nekumwe kuedza.Uye mushure mekuiswa, zvakakosha kugadzirisa gaka rekushisa pakati pemaoko e rocker nemavharuvhu.
Panguva yekushanda kwemotokari, rocker arm axle haidi kugadziriswa kwakakosha, zvinongodiwa chete maererano nemirairo yekutarisa kupindira kwemabhaudhi / nzungu uye kuongorora zvikamu zveaxle zvekuvimbika kwavo.Kugara kugadziridzwa uye kushanda kwakakodzera kwemotokari kunovimbisa kushanda kwakavimbika kweiyo rocker arm axle uye nguva yakazara mune ese injini inoshanda modes.
