Yenziwe ngezinto ezinjani i-axle engasemva yemoto kwaye idityaniswa njani?
Izinto kunye nendlela yokuwelda ye-axle engasemva ziyahluka kakhulu ngokuxhomekeke kwimodeli yesithuthi, injongo (njengeelori ezinzima okanye iimoto zabakhweli), kunye nemisebenzi yecandelo. Yahlulwe kakhulu kwiindidi ezimbini: i-cast axle housing kunye ne-stamped-welded axle housing. Izixhobo kunye neenkqubo zokuwelda nazo zahlukile ngokufanelekileyo.
Izinto eziphambili ze-axle yangasemva
I-axle engasemva yesithuthi ayiyonto inye kodwa yenziwe ngezinto ezininzi. Izinto eziphambili ziquka:
Intsimbi eqingqiweyo: Isetyenziswa kakhulu kwiindawo zokugcina ii-axle zangasemva zeelori ezinzima kunye nezithuthi zorhwebo, inamandla aphezulu, iqinile kakhulu, kwaye inomthamo omhle wokuthwala umthwalo. Okwangoku yeyona iphambili kwimarike. Umzekelo, iindawo ezininzi zokugcina ii-axle zangasemva zeelori zisebenzisa i-ZG45 kunye nezinye izinto zentsimbi eqingqiweyo.
Isinyithi se-Ductile/i-spheroidal graphite: Isetyenziswa rhoqo ekubumbeni ii-axle housings, inexabiso eliphantsi kwaye iyakwazi ukufunxa kakuhle i-shock, kodwa amandla ayo kunye nokumelana nokuqhekeka kuphantsi kunesinyithi esityhidiweyo. Ihlala ibonakala kwiimodeli ezithile eziphakathi ukuya kwezisezantsi okanye izinto ezithile.
Intsimbi ye-alloy/intsimbi enamandla aphezulu: Isetyenziselwa iigobolondo eziphezulu nezisezantsi zendlu ye-axle edibeneyo kunye nemikhono ye-half-shaft, efana ne-16Mn, 40MnB, Q345, njl., inobuxhakaxhaka obuhle kunye nokuqina.
I-alloy ye-aluminium: Isetyenziswa kakhulu kwiimoto zabakhweli ezikumgangatho ophezulu nakwiimodeli ezikhaphukhaphu. Umzekelo, i-axle engasemva yeMercedes-Benz GLE450 isebenzisa i-alloy ye-aluminium, enezibonelelo zobunzima obulula, ukumelana nokugqwala, kunye nokusasaza ubushushu kakuhle, kodwa inkqubo yokudibanisa ifuna imigangatho ephezulu.
Iityhubhu zentsimbi ezikhethekileyo ezingenamthungo: Ezisetyenziselwa izindlu ze-axle eziqhutywayo, zenziwe ngentsimbi ekhethekileyo enamandla okutsalwa afikelela kwi-680 MPa kwaye zinamandla okuvelisa angama-550 MPa, ngokwenziwa kokwandiswa okubandayo, ngaphandle kwemithungo yokuwelda, kwaye zisebenza kakuhle kakhulu.
Izixhobo zeGiya: Iigiya zeplanethi, iigiya zesiqingatha seshaft, njl.njl. ngaphakathi kwi-axle yangasemva zihlala zisebenzisa i-20CrMnTi kunye nezinye iintsimbi ze-alloy ezine-carburised ukuqinisekisa ukumelana nokuguguleka kunye nokumelana nempembelelo.
Indlela yokuwelda ye-axle yangasemva
Ukuwelda kwe-axle yangasemva kufuna ukukhethwa kwezinto ezithile zokuwelda kunye neenkqubo ezisekelwe kwizinto ezisetyenzisiweyo. Isitshixo sikukukwazi ukumelana nokuqhekeka kunye namandla okulingana:
Ukuwelda kwendlu ye-axle yangasemva yentsimbi ephosiweyo:
Izinto zokuwelda ezicetyiswayo: Iintonga zokuwelda zentsimbi ye-WEWELDING600 alloy, ezinamandla okutsalwa aphezulu ukuya kuthi ga kwi-860 MPa kunye nobude obuphezulu, ezenzelwe ngokukodwa iindawo zentsimbi ezidityanisiweyo ezinoxinzelelo oluphezulu, ezinokuthintela ngempumelelo ukuqhekeka kwe-weld.
Izixhobo zokuwelda ezikhethiweyo: Iintonga zokuwelda ze-J506 (E5016) zingasetyenziselwa iindawo ezingezizo ezibalulekileyo okanye ukulungiswa okwethutyana, kodwa kukho umngcipheko wokuqhekeka kwe-weld, kwaye ayikhuthazwa kwiindawo ezibalulekileyo ezithwala umthwalo.
Indlela yokuwelda: Kubalulekile ukucoca amabala eoyile, ukwenza ii-bevels, ukulawula ubushushu, ukuphepha ukuwelda okuphindaphindiweyo, kwaye xa kuyimfuneko, ukwenza ukufudumeza kwangaphambili kunye nokucothisa ukupholisa.
Ukuwelda kwendlu ye-axle yangasemva yentsimbi ephoswe ngentsimbi (engaxhaphakanga kangako, ixhaphake kakhulu kwiimodeli ezindala okanye iitrektara):
Izinto zokuwelda ezicetyiswayo: WEWELDING777 iintonga zokuwelda zesinyithi esityhidiweyo, kusetyenziswa iteknoloji yokuwelda ebandayo, akukho mfuneko yokufudumeza kwangaphambili, kwaye ukumelana nokuqhekeka kugqwesileyo, lukhetho olukhethwayo lokulungisa iindawo zesinyithi esityhidiweyo.
Amanyathelo okhuseleko: Iintambo zokuwelda eziqhelekileyo zinokubangela ukuqhekeka okubuthathaka, iindawo zesinyithi ezibunjiweyo azifanelekanga ukuwelda ngokuphindaphindiweyo, kungenjalo, zinokuba "nokungaphumeleli kokuwelda".
Ukuwelda kwendlu yee-axle eziweldiweyo ezistampu (iipleyiti zentsimbi):
Sebenzisa ikakhulu i-welding yokukhusela igesi (MIG/MAG) okanye i-arc welding ngesandla, izinto zokuwelda zihambelana nezinto ezisisiseko, ezifana ne-ER70S-6 welding wire okanye ii-J507 welding rods.
Unxibelelwano phakathi kwesinqe se-half-shaft kunye ne-axle housing ludla ngokusebenzisa i-plug welding ukuphucula amandla onxibelelwano.
Ukuwelda kwe-axle yangasemva ye-aluminium alloy:
Iintambo zokuwelda ze-aluminium ezikhethekileyo (ezifana ne-ER4043 okanye i-ER5356) kunye nenkqubo yokuwelda ye-TIG ziyafuneka.
Ngaphambi kokuwelda, ifilimu ye-oxide kufuneka isuswe ngokupheleleyo, ngexesha lokuwelda, ubushushu kufuneka bulawulwe ngokungqongqo ukuthintela ukuguquka kunye nokuqhekeka okushushu.
