Ndi mafuta ati oti mudzaze mu variator?
Makhalidwe ogwirira ntchito amafuta a CVT
Kutumiza kwamtundu wodziwikiratu kumasintha pang'onopang'ono koma motsimikizika m'malo mwa mabokosi amsika. Mtengo wopangira makina odzipangira okha umachepetsedwa, ndipo kudalirika kwawo ndi kulimba kwawo kumawonjezeka. Kuphatikizidwa ndi chitonthozo choyendetsa galimoto cha automatics poyerekeza ndi kutumiza kwamanja, izi ndizomveka.
Zosintha (kapena CVT, zomwe m'matembenuzidwe osinthidwa amatanthauza "kutumiza kosinthika mosalekeza") sizinasinthenso zazikulu pamapangidwe kuyambira pomwe zidayamba. Kudalirika kwa lamba (kapena unyolo) kwawonjezeka, kugwira ntchito bwino kwawonjezeka ndipo moyo wonse wautumiki wopatsirana wawonjezeka mpaka kuvala kovuta.
Komanso, ma hydraulics, chifukwa cha kuchepa kwa kukula kwa zinthu zomwe zimagwira ntchito komanso kuchuluka kwa katundu wawo, zidayamba kufuna kulondola kwambiri. Ndipo izi, nazonso, zikuwonetsedwa muzofunikira zamafuta a CVT.
Mosiyana ndi mafuta a ATF omwe amapangidwa kuti azigwiritsidwa ntchito pamakina wamba, mafuta othamanga osinthika amagwira ntchito mwatsatanetsatane.
Choyamba, sayenera kuchotseratu kuthekera kwawo kolemeretsa ndi thovu la mpweya ndipo, chifukwa chake, mawonekedwe amtundu wa compressibility. Ma hydraulics, omwe amasuntha ndikukulitsa mbale panthawi yamagetsi, ayenera kugwira ntchito momveka bwino momwe angathere. Ngati, chifukwa cha mafuta oyipa, mbale zimayamba kugwira ntchito molakwika, izi zidzapangitsa kuti pakhale kutsekemera kapena mosiyana, kufooka kwakukulu kwa lamba. Pachiyambi choyamba, chifukwa cha kuchuluka kwa katundu, lamba adzayamba kutambasula, zomwe zidzachititsa kuchepa kwa gwero lake. Ndi kukanidwa kosakwanira, kumatha kuyamba kutsika, zomwe zingayambitse kuvala pa mbale ndi lamba wokha.
Kachiwiri, mafuta a CVT amayenera kuthira mafuta nthawi imodzi ndikuchotsa kuthekera kwa lamba kapena unyolo pa mbale. Mumafuta a ATF amakina odziyimira pawokha, kutsetsereka pang'ono kwamawotchi panthawi yosinthira bokosi ndikwachilendo. Unyolo muzosintha uyenera kugwira ntchito ndikutsika pang'ono pama mbale. Moyenera, palibe kuterera konse.
Ngati mafuta ali ndi mafuta ochuluka kwambiri, ndiye kuti izi zidzapangitsa kuti lamba (unyolo) azitsetsereka, zomwe sizovomerezeka. Zotsatira zofananira zimatheka pogwiritsa ntchito zowonjezera zapadera, zomwe, pakukhudzana kwambiri ndi mikangano ya lamba-mbale, zimataya zina zamafuta awo.
Kugawika kwa mafuta a gear kwa ma variators
Palibe gulu limodzi lamafuta a CVT. Palibe mikhalidwe yokhazikika, yanthawi zonse yomwe imakhudza mafuta ambiri a CVT, monga odziwika bwino a SAE kapena API classifiers mafuta opangira mafuta.
Mafuta a CVT amagawidwa m'njira ziwiri.
- Amasindikizidwa ndi wopanga ngati mafuta opangira mabokosi apadera amitundu yamagalimoto. Mwachitsanzo, mafuta a CVT pamagalimoto ambiri a Nissan CVT amalembedwa kuti Nissan ndipo ndi NS-1, NS-2, kapena NS-3. Mafuta a Honda CVT kapena CVT-F nthawi zambiri amatsanuliridwa mu Honda CVTs. Ndi zina zotero. Ndiye kuti, mafuta a CVT amalembedwa ndi mtundu wa automaker ndi kuvomerezedwa.
- Zolembedwa pa kulolerana. Izi ndizochokera mumafuta a CVT omwe sanatchulidwe ngati mafuta amtundu wina wagalimoto. Monga lamulo, mafuta omwewo ndi abwino kwa mitundu ingapo yamitundu yosiyanasiyana yomwe idayikidwa pamapangidwe osiyanasiyana ndi mitundu yamagalimoto. Mwachitsanzo, CVT Mannol Variator Fluid ili ndi zovomerezeka zopitilira khumi ndi ziwiri za CVT zamagalimoto aku America, Europe ndi Asia.
Chofunikira pakusankha koyenera kwa mafuta kwa variator ndi kusankha kwa wopanga. Monga momwe zasonyezera, pali mafuta ambiri amtundu wokayikitsa pamsika. Moyenera, ndi bwino kugula mafuta odzola odziwika kwa ogulitsa ovomerezeka. Amapangidwa nthawi zambiri kuposa mafuta achilengedwe.
