Kodi mafuta abwino kwambiri ndi ati? Kuyang'ana yabwino kumango

Zofunikira pakuwunika magiya amafuta pamayendedwe apamanja

Mafuta okhazikika pamapako amanja ali ndi zisonyezo ziwiri zazikulu zomwe zimatsimikizira kuthekera kwawo kugwira ntchito m'magawo ena opatsirana: kalasi yamafuta a API ndi kukhuthala. Izi ndizomwe zimadziwika kwambiri pakugawika kwamafuta amagetsi.

Kupatsirana pamakina, kwenikweni, ndi gulu la magiya odzaza kwambiri, mitsinje yake yomwe imazungulira mozungulira. Njira zowongolera, mapiko ndi mafoloko, ndizochepa kwambiri. Choncho, palibe kutsindika kwapadera pa kudzoza kwawo, chifukwa mafuta aliwonse opatsirana nthawi zambiri amakhala okwanira kuti azigwira ntchito bwino pamakinawa.

Ma Synchronizers amagwiranso ntchito yofunikira pakutumiza kwamanja. Chofunika kwambiri cha synchronizer ndi kugwirizanitsa liwiro la magiya okwerera musanayambe kuchita. Ngati magiya azungulira pa liwiro losiyana, zimakhala zovuta kupanga chinkhoswe popita. Nthawi zambiri, kulephera kwa ma synchronizer kumadziwika ndi kulumikizidwa kolimba kwa magiya okhala ndi chitsulo chokhazikika.

Synchronizer imagwira ntchito mosavuta. Musanaphatikize magiya, mukasuntha magiya, choyamba cholumikizira chamtundu wa synchronizer chimakumana ndi mbali yam'mphepete mwa imodzi mwa magiya ndipo, chifukwa cha mphamvu yakugundana, imafanana ndi liwiro la kuzungulira kwa magiya onse awiri. Pambuyo pake, magiya amalumikizana mosavuta komanso popanda mawu akunja. Koma ngati pali zowonjezera zowonjezera zotsutsana ndi zotsutsana mu mafuta, ndiye kuti synchronizer imayamba kutsetsereka pambali pa giya. Liwiro lozungulira silingafanane. Bokosilo liyamba kusagwira ntchito.

Zikuwonekeratu kuti mafuta a gear ayenera kukwaniritsa izi mpaka pamlingo waukulu:

• tetezani magiya odzaza kuti asavale ndi kugwa;
• bwino mafuta anagubuduza mayendedwe;
• musasokoneze ntchito ya synchronizers ndi magawo ena olamulira;
• kuchita ntchito zawo kwa nthawi yaitali.

Kukwera kwapamwamba kwa kuphatikiza kwa njira zowunikira izi, kumapangitsa kuti mafuta agiya akhale abwino.

Mafuta abwino kwambiri amafuta

Zomwe zimachitika ndi mafuta a gear ndizosavuta: kukweza mtengo wamafuta, kumateteza bwino kufalitsa kwamanja kuti zisavale komanso kukhalitsa. Komabe, musaiwale kuti muyenera kusankha mafuta mosamalitsa a kalasi ndi mamasukidwe akayendedwe, amene akulimbikitsidwa ndi wopanga galimoto ndi zogwirizana ndi nyengo.

Mwachitsanzo, mafuta amagulu a GL-3 ndi GL-4 (pafupifupi analogue yathunthu yapakhomo TM-3 ndi TM-4) akulimbikitsidwa kuti azitha kutumizirana mauthenga, pomwe, pamaso pa giya la hypoid mu giya yayikulu, katundu sadutsa 2500 MPa ndi 3000 MPa, motero.

Mafuta ochulukirapo aukadaulo a GL-5 ndi GL-6 (TM-5 ndi TM-6) amatha kuteteza magiya ndi ma bere okha mogwira mtima, koma sagwirizana ndi ma transmissions ena olumikizidwa.

Zimakhala zovuta kuwunika momwe mafuta operekera amaperekera pakanthawi kochepa, chifukwa nthawi zosinthira nthawi zambiri zimadutsa 60-80 km. Choncho, m'munsimu tikulemba mndandanda wa opanga mafuta a gear omwe eni ake amawalankhula bwino:

• Chigoba;
• Elf;
• Fuchs;
• Castrol;
• Zamadzimadzi Moly;
• Motuli;
• Mannol.

Mwa opanga zoweta mwamwambo Gazpromneft, Lukoil ndi Rosneft ndi atsogoleri.

Mafuta abwino kwambiri a VAZ

Tiyeni tiwone mwachidule mafuta abwino kwambiri agalimoto a AvtoVAZ.

1. kunena. Izi wopanga mafuta Korea ndi molimba mtima kugonjetsa misika ya Chitaganya cha Russia, makamaka m'dera la eni galimoto VAZ. Pakati pa mafuta a gear, oyendetsa galimoto amalankhula bwino za G-FF class GL-4 synthetics. Mafuta awa ndi oyenera mabokosi a zitsanzo tingachipeze powerenga (VAZ-2101 kuti Vaz-2107), ndipo kenako - mabanja Samara, Vaz-2110 ndi Samara-2 (VAZ-2114). M'mitundu yaposachedwa ya VAZ, GF TOP class GL-4/5 synthetics ndiyoyenera.
2. Agip. Wopanga wodziwika pang'ono uyu amakondedwa ndi eni ake ambiri a VAZ ndi gearbox yamanja. Mafuta, ngakhale ndi a theka-synthetics, koma, tikayang'ana ndemanga za oyendetsa, amagwira ntchito bwino ngakhale m'mabokosi a zitsanzo zamakono, monga Grant ndi Priora. Mafuta a gear a Agip Rotra amapangidwa mumitundu yambiri yama viscosities, koma njira zodziwika kwambiri ndi 75W-90 ndi 75W-80, zomwe zili bwino kwambiri pakati ndi kumpoto kwa Russian Federation. M'madera okhala ndi nyengo yotentha, mafuta odzola amagwiritsidwa ntchito.

3. Lukoil. Mwina opanga otchuka kwambiri mafuta zida magalimoto zoweta mu Russian Federation. Lukoil TM-5 wa kalasi GL-5 ndi mamasukidwe akayendedwe a 85W-90 nthawi zambiri ntchito kwa Niva. Lukoil akulimbikitsidwanso kudzaza ndi eni zitsanzo zina za VAZ. M'mabwalo oyendetsa galimoto, pali lingaliro lakuti mafuta awa ndi abwino kwambiri potengera chiŵerengero cha mtengo / khalidwe.
4. Gazpromneft. Tsopano imayang'ana kwambiri pakupanga mafuta amagetsi opangira zodziwikiratu, koma pali mafuta ambiri osavuta omwe amagulitsidwa pamanja. Pa intaneti nthawi zambiri pamakhala ndemanga kuchokera kwa eni ake a Kalin, omwe amalankhula zabwino za mafuta awa.
5. Rosneft. Mafuta a mzere wa Kinetic Hypoid samangokhala ndi chilolezo chovomerezeka ndi AvtoVAZ PJSC, komanso adasonkhanitsa ndemanga zambiri zabwino kuchokera kwa eni magalimoto. Oyendetsa galimoto amawona kusuntha kosavuta ndi kusunga mafuta m'nyengo yozizira, zomwe zimapangitsa kuti zikhale zosavuta kuyamba kuyendetsa galimoto m'nyengo yozizira.

Ndemanga zoipa za mafuta zida makamaka zokhudzana ndi kukhuthala kolakwika kapena kalasi, komanso kuchedwa m'malo.

Ndi mafuta ati omwe ali bwino, kuyesa 1
