Transmission amafutha: ngezigaba kanye nezici

amafutha Gear - isigaba esikhethekile injini amafutha yenzelwe ukusetshenziswa ISIZINDA ezahlukene izimoto ngomshikisho ukudluliswa, kanye ezihlukahlukene igiya. Motor futhi igiya amafutha ekhiqizwa wezokumbiwa phansi noma zokwenziwa isizinda, bese doped nge ezihlukahlukene izithasiselo, kodwa izimfuneko ukudluliswa baphakeme, ngoba usebenze ngezinga imithwalo kakhulu kunalokhu futhi isheshisa isiliphu friction evele. Omunye izinkomba ebaluleke kakhulu amafutha enjalo yikhono ukudala ifilimu zokuzivikela phezu amayunithi ukuhilizisana ukuze ugweme ukuxhumana mechanical phakathi kwazo. I hypoid igiya asetshenziswa amafutha, okuyinto, engena ezindlini ngezindlu ukusabela ikhemikhali evele zezitho, ukuvimbela nabo skipanie ifa kakhulu ingcindezi izakhiwo. Ngesikhathi kokuhlinzwa, amafutha igiya oxidize futhi babe enobuthi futhi kudingeka ukushintshwa ngezikhathi ezithile. Lokhu ibhekwa okuhle lapho mafutha ukuthambekela ongaphakeme ukuze namachibi. Njengoba abakhiqizi ezahlukene zisebenzisa izithasiselo ezahlukene uhlanganise imikhiqizo yabo abakwazi. Lapho esikhundleni ukudluliswa iyunithi kufanele ngokuphelele engahashazanga, uma kungenzeka okufanayo ngamafutha amasha.

amafutha Gear ihlukaniswa noma viscosity noma Ukusebenza. Ngakho, ngokuvumelana Sae (Association of Izithuthi Onjiniyela) bahlukene ku ayisishiyagalolunye amakilasi - ezinhlanu ehlobo futhi ezine ebusika (onenkomba W). Salelo nalelo class ecacisiwe viscosity Inkomba. Sae Sae 70W noma 250, isibonelo. Inkomba Dual kuboniswe ngoba amafutha multigrade (Sae 80W-90, njll).

API (American petroleum Institute) uhlukanisa amafutha 6 amakilasi, kuncike izakhiwo tekusebenta - GL-1 ... GL-6. La makilasi kukhona ezifana nalezo ezazisetshenziselwa ukwenza eSoviet GOST 17479.2-85 TM1 ... TM6. Iqembu lesithathu nelesine asetshenziselwa amagiya hypoid futhi ube lubricity ophakeme kakhulu ingcindezi ukusebenza.

Lapho ekhetha igiya amafutha, kufanele lapha igxila ngokuyinhloko izimo zabo zokusebenza. Uma isigaba lingaphansi kunalokhu kudingekile, mane nje indlela ehluleka, futhi ayanda ebangeni uwoyela has a intengo ephakeme, okuyoholela izindleko overruns. Kubalulekile futhi ukuba ucabangele okushisa lapho ukudluliswa izosebenza, futhi ngaleli ngesisekelo ukukhetha ukuphila kube mnandi kuphela. Sae 85W, isibonelo, ezosebenza okushisa ukuze -12 ° C, futhi 85W kufanele -40 ° C. Ngo omoya othomathikhi , a ekhethekile ongaphakeme-viscosity uketshezi, ngakho akukho injini noma ukudluliswa uwoyela khona azisebenzi.

Namuhla emakethe uhla enkulu abakhiqizi ukunikela gear yabo amafutha - Lukoil, Ubude, Texaco, Reksol, amaNorseman nabanye abaningi. A ezihlukahlukene izithasiselo esetshenziswa inquma lizinga izinga amafutha kanye intengo zabo ezahlukene. Mineral ngokuvamile eshibhile, kodwa zokwenziwa kancane njengoba okuphambene. A ebucayini ezinhle, kwakungaba ke lulwimi zokwenziwa njengoba osebenzelana nokujabulisayo phakathi ezimbili zokuqala. Kufanele futhi uqaphele elinegazi hhayi ukuthenga uwoyela ezitolo engahloliwe. Shintsha ibhokisi uhlale eqolo ngaphezu kwanoma ukuthatha uwoyela izinga okuhle, ikakhulukazi manje ukuthi esikhundleni kuze abasuse wanakekelwa amakhilomitha ayizinkulungwane ezingu-60 noma ngaphezulu.
