Kodi chogwirira chakumbuyo cha galimotocho chimapangidwa ndi zinthu ziti ndipo chimalumikizidwa bwanji?
Zipangizo ndi njira zowotcherera za axle yakumbuyo zimasiyana kwambiri kutengera mtundu wa galimoto, cholinga chake (monga magalimoto akuluakulu kapena magalimoto onyamula anthu), ndi ntchito za zigawo zake. Zimagawidwa m'magulu awiri: nyumba yopangidwa ndi axle yopangidwa ndi stamped-welded axle. Zipangizo ndi njira zowotcherera zimasiyananso moyenerera.
Zipangizo zazikulu za chitsulo chakumbuyo
Chogwirira chakumbuyo cha galimoto si chinthu chimodzi koma chimapangidwa ndi zinthu zingapo. Zipangizo zazikulu ndi izi:
Chitsulo chopangidwa ndi chitsulo: Chimagwiritsidwa ntchito kwambiri m'magawo ozungulira kumbuyo kwa magalimoto akuluakulu ndi magalimoto amalonda, chili ndi mphamvu zambiri, kulimba kwambiri, komanso mphamvu yabwino yonyamula katundu. Pakadali pano ndi chomwe chimagwiritsidwa ntchito kwambiri pamsika. Mwachitsanzo, magawo ambiri ozungulira kumbuyo kwa magalimoto amagwiritsa ntchito ZG45 ndi zipangizo zina zopangidwa ndi chitsulo.
Chitsulo cha ductile/spheroidal graphite: Chimagwiritsidwa ntchito nthawi zambiri popanga ma axle housing, chimakhala ndi mtengo wotsika komanso chimayamwa bwino ma shock, koma mphamvu zake ndi kukana ming'alu ndizochepa poyerekeza ndi chitsulo chopangidwa. Chimawoneka kawirikawiri m'mitundu ina yapakati mpaka yotsika kapena zigawo zinazake.
Chitsulo chopangidwa ndi aloyi/chitsulo champhamvu kwambiri: Chogwiritsidwa ntchito pa zipolopolo zapamwamba ndi zapansi za nyumba yolumikizidwa ndi axle ndi manja a theka la shaft, monga 16Mn, 40MnB, Q345, ndi zina zotero, chili ndi kuwotcherera kwabwino komanso kulimba.
Aluminiyamu: Amagwiritsidwa ntchito kwambiri m'magalimoto okwera okwera apamwamba komanso m'magalimoto opepuka. Mwachitsanzo, axle yakumbuyo ya Mercedes-Benz GLE450 imagwiritsa ntchito aloyi ya aluminiyamu, yomwe ili ndi ubwino wopepuka, kukana dzimbiri, komanso kutentha bwino, koma njira yowotcherera imafuna miyezo yapamwamba.
Machubu apadera achitsulo chosasunthika: Amagwiritsidwa ntchito popanga ma axle oyendetsera, amapangidwa ndi chitsulo chapadera chokhala ndi mphamvu yokoka mpaka 680 MPa ndi mphamvu yotulutsa ya 550 MPa, kudzera mu kukulitsa kozizira, popanda mipata yolumikizira, ndipo amagwira ntchito bwino kwambiri.
Zipangizo za zida: Magiya a pulaneti, magiya a theka-shaft, ndi zina zotero mkati mwa axle yakumbuyo nthawi zambiri amagwiritsa ntchito zitsulo za 20CrMnTi ndi zitsulo zina za alloy zophimbidwa ndi carburised kuti zitsimikizire kukana kuwonongeka ndi kukana kugunda.
Njira yowotcherera ya axle yakumbuyo
Kuwotcherera kwa axle yakumbuyo kumafuna kusankha zipangizo zinazake zowotcherera ndi njira zogwiritsira ntchito kutengera zinthuzo. Chofunika kwambiri ndi kuthekera kolimbana ndi ming'alu ndi mphamvu zofanana:
Kuwotcherera kwa nyumba yachitsulo chakumbuyo yachitsulo chopangidwa ndi chitsulo:
Zipangizo zolumikizira zovomerezeka: Ndodo zolumikizira zitsulo za WEWELDING600, zokhala ndi mphamvu yokoka mpaka 860 MPa komanso kutalika kwambiri, zopangidwa makamaka kuti zigwiritsidwe ntchito pazida zachitsulo zosungunuka kwambiri, zomwe zingalepheretse kusweka kwa weld.
Zipangizo zolumikizira zosankha: Ndodo zolumikizira za J506 (E5016) zitha kugwiritsidwa ntchito pazinthu zosafunikira kapena kukonza kwakanthawi, koma pali chiopsezo cha kuswedwa kwa weld, ndipo sizikulimbikitsidwa pazinthu zofunika zonyamula katundu.
Njira yowotcherera: Ndikofunikira kuyeretsa madontho a mafuta, kupanga ma bevel, kuwongolera kutentha, kupewa kuwotcherera mobwerezabwereza, ndipo ngati kuli kofunikira, kutentha pasadakhale komanso kuziziritsa pang'onopang'ono.
Kuwotcherera kwa nyumba ya axle yakumbuyo yachitsulo chopangidwa ndi chitsulo (yosazolowereka, yomwe imapezeka kwambiri m'magalimoto akale kapena mathirakitala):
Zipangizo zolumikizira zovomerezeka: Ndodo zolumikizira zitsulo za WEWELDING777, pogwiritsa ntchito ukadaulo wolumikizira wozizira, palibe kutenthetsa kofunikira, ndipo kukana ming'alu ndikwabwino kwambiri, ndiye chisankho chomwe chimakondedwa pokonza zida zachitsulo cholumikizira.
Chenjezo: Ndodo zowotcherera wamba zimatha kuyambitsa ming'alu yosweka, zitsulo zotayidwa siziyenera kuwotcherera mobwerezabwereza, apo ayi, zimatha "kulephera kuwotcherera".
Kuwotcherera kwa nyumba yolumikizidwa ndi axle (mapepala achitsulo):
Gwiritsani ntchito kwambiri welding yoteteza mpweya (MIG/MAG) kapena welding ya arc yamanja, zinthu zowetera zimagwirizana ndi zinthu zoyambira, monga waya wowetera wa ER70S-6 kapena ndodo zowetera za J507.
Kulumikizana pakati pa half-shaft sleeve ndi axle housing nthawi zambiri kumagwiritsa ntchito plug welding kuti kuwonjezere mphamvu yolumikizira.
Kuwotcherera kwa axle yakumbuyo ya aluminiyamu:
Mawaya apadera olumikizira aluminiyamu (monga ER4043 kapena ER5356) ndi njira yolumikizira ya TIG ndizofunikira.
Musanagwiritse ntchito chotenthetsera, filimu ya oxide iyenera kuchotsedwa bwino, panthawi yogwiritsa ntchito chotenthetsera, kutentha kuyenera kulamulidwa mosamala kuti kupewe kusinthika ndi ming'alu yotentha.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
