I-axle yangemuva yemoto yenziwe ngani futhi ishiselwe kanjani?
Indlela yezinto zokwakha kanye nendlela yokushisela ye-axle yangemuva iyahlukahluka kakhulu kuye ngemodeli yemoto, injongo (njengamaloli athwala kanzima noma izimoto zabagibeli), kanye nemisebenzi yezingxenye. Ihlukaniswe kakhulu ngezigaba ezimbili: indlu ye-axle ehlanganisiwe kanye nendlu ye-axle ehlanganisiwe. Izinto zokwakha kanye nezinqubo zokushisela nazo ziyahlukahluka ngokufanele.
Izinto eziyinhloko ze-axle yangemuva
I-axle yangemuva yemoto akuyona into eyodwa kodwa yakhiwe yizingxenye eziningi. Izinto eziyinhloko zifaka:
Insimbi ehlanganisiwe: Isetshenziswa kabanzi ezindlini ze-axle yangemuva zamaloli asindayo nezimoto zezentengiselwano, inamandla aphezulu, iqinile kakhulu, futhi inomthamo omuhle wokuthwala imithwalo. Njengamanje iyindawo evame kakhulu emakethe. Isibonelo, izindlu eziningi ze-axle yangemuva zamaloli zisebenzisa i-ZG45 nezinye izinto zensimbi ehlanganisiwe.
Insimbi ye-Ductile iron/spheroidal graphite: Ivame ukusetshenziswa ekubunjweni kwe-axle housings, inezindleko eziphansi kanye nokumuncwa okuhle kokushaqeka, kodwa amandla ayo kanye nokumelana nokuqhekeka kuphansi kunensimbi ehlanganisiwe. Ivame ukubonakala kwamanye amamodeli aphakathi kuya kwaphansi noma izingxenye ezithile.
Insimbi ye-alloy/insimbi enamandla amakhulu: Isetshenziselwa amagobolondo aphezulu nangaphansi e-axle ehlanganisiwe enezitembu kanye nemikhono ye-half-shaft, njenge-16Mn, 40MnB, Q345, njll., inokushisela okuhle kanye nokuqina.
I-aluminium alloy: Isetshenziswa kakhulu ezimotweni zabagibeli ezisezingeni eliphezulu kanye namamodeli alula. Isibonelo, i-axle yangemuva ye-Mercedes-Benz GLE450 isebenzisa i-aluminium alloy, enezinzuzo zesisindo esilula, ukumelana nokugqwala, kanye nokushabalalisa ukushisa okuhle, kodwa inqubo yokushisela idinga amazinga aphezulu.
Amashubhu ensimbi akhethekile angenamthungo: Asetshenziselwa izindlu ze-axle ezihlanganisiwe, enziwe ngensimbi ekhethekile enamandla okunamathela afinyelela ku-680 MPa kanye namandla okukhiqiza angu-550 MPa, ngokwakhiwa kokukhula okubandayo, ngaphandle kwemithungo yokushisela, futhi asebenza kahle kakhulu.
Izinto zokusebenzisa amagiya: Amagiya eplanethi, amagiya e-half-shaft, njll. ngaphakathi kwe-axle yangemuva ngokuvamile asebenzisa i-20CrMnTi kanye nezinye izinsimbi ze-alloy ezifakwe i-carburized ukuqinisekisa ukumelana nokuguguleka kanye nokumelana nokushayisana.
Indlela yokushisela ye-axle yangemuva
Ukushisela kwe-axle yangemuva kudinga ukukhethwa kwezinto zokushisela ezithile kanye nezinqubo ezisekelwe ezintweni. Isihluthulelo sisekukwazini ukumelana nokuqhekeka kanye namandla afanayo:
Ukushisela kwendlu ye-axle yangemuva yensimbi ephothiwe:
Izinto zokushisela ezinconywayo: Izinduku zokushisela zensimbi ze-WEWELDING600, ezinamandla okunamathela afinyelela ku-860 MPa kanye nobude obuphezulu, ezenzelwe ngqo izingxenye zensimbi ezicindezelwe kakhulu, ezingavimbela ngempumelelo ukuqhekeka kwe-weld.
Izinto zokushisela ongazikhetha: Izinduku zokushisela ze-J506 (E5016) zingasetshenziswa ezingxenyeni ezingezona ezibalulekile noma ekulungisweni kwesikhashana, kodwa kunengozi yokuqhekeka kokushisela, futhi akukhuthazwa ezingxenyeni ezibalulekile ezithwala umthwalo.
Indlela yokushisela: Kuyadingeka ukuhlanza amabala kawoyela, ukwenza ama-bevel, ukulawula ukufakwa kokushisa, ukugwema ukushisela okuphindaphindiwe, futhi uma kudingeka, ukwenza ukushisisa kusengaphambili nokupholisa kancane.
Ukushisela indlu ye-axle yangemuva yensimbi ephothiwe (okungavamile, okubonakala kakhulu kumamodeli amadala noma ogandaganda):
Izinto zokushisela ezinconywayo: Izinduku zokushisela zensimbi ezihlanganisiwe ze-WEWELDING777, kusetshenziswa ubuchwepheshe bokushisela obubandayo, akudingeki ukushisa kusengaphambili, futhi ukumelana nokuqhekeka kuhle kakhulu, kuyisinqumo esikhethwayo sokulungisa izingxenye zensimbi ezihlanganisiwe.
Izinyathelo Zokuqapha: Izinduku zokushisela ezivamile zivame ukubangela ukuqhekeka okubuthakathaka, izingxenye zensimbi ezibunjiwe azifaneleki ukushisela okuphindaphindiwe, ngaphandle kwalokho, zivame "ukwehluleka ukushisela".
Ukushisela kwendlu ye-axle eshiselwe nge-stamped-welded (amapuleti ensimbi):
Sebenzisa kakhulu ukushisela kokuvikela igesi (MIG/MAG) noma ukushisela ngesandla kwe-arc, izinto zokushisela zihambisana nezinto eziyisisekelo, njenge-wire welding ye-ER70S-6 noma izinduku zokushisela ze-J507.
Ukuxhumana phakathi kwesikhafu se-half-shaft kanye ne-axle housing kuvame ukusebenzisa ukushisela amapulagi ukuze kuthuthukiswe amandla okuxhuma.
Ukushisela i-axle yangemuva ye-aluminium alloy:
Kudingeka izintambo zokushisela ze-aluminium ezikhethekile (njenge-ER4043 noma i-ER5356) kanye nenqubo yokushisela ye-TIG.
Ngaphambi kokushisela, ifilimu ye-oxide kumele isuswe kahle, ngesikhathi sokushisela, izinga lokushisa kumele lilawulwe ngokuqinile ukuze kuvinjelwe ukuguquka kanye nokuqhekeka okushisayo.
