Uma abantu bexoxa ngezithuthuthu ezinamasondo amathathu namaloli amancane namaveni, bavame ukuthi le eseli intanta ngokuphelele, futhi leyo eseli intanta kancane.Kusho ukuthini "ukuntanta okugcwele" kanye "nokuntanta okuncane" lapha?Ake siphendule lo mbuzo ongezansi.
Okubizwa ngokuthi "i-full-floating" kanye "ne-semi-floating" kubhekisela ohlotsheni lokusekelwa okukhwezwayo kwama-axle shafts ezimoto.Njengoba sonke sazi, i-half shaft iyi-shaft eqinile ehambisa i-torque phakathi kwe-different namasondo okushayela.Uhlangothi lwayo lwangaphakathi luxhunywe negiya eliseceleni nge-spline, kanti uhlangothi lwangaphandle luxhunywe nehabhu lesondo lokushayela eline-flange.Njengoba i-half shaft idinga ukuthwala i-torque enkulu kakhulu, amandla ayo ayadingeka ukuba abe phezulu kakhulu.Ngokuvamile, insimbi ye-alloy efana ne-40Cr, 40CrMo noma 40MnB isetshenziselwa ukucisha nokuthambisa kanye nokwelashwa kokucisha imvamisa ephezulu.Ukugaya, ingqikithi inokuqina okuhle, ingakwazi ukumelana ne-torque enkulu, futhi ingamelana nomthwalo othile womthelela, ongahlangabezana nezidingo zezimoto ngaphansi kwezimo ezihlukahlukene.
Ngokwezinhlobo ezahlukene ezisekelayo ze-half shafts, i-half shafts ihlukaniswe yaba izinhlobo ezimbili: "ezintantayo ezigcwele" kanye "ne-semi-floating".I-ekseli entanta ngokugcwele kanye ne-ekseli entanta kancane esivame ukubhekisela kuyo empeleni ibhekisela ohlotsheni lwe-half-shaft."Ukuntanta" lapha kubhekisela kumthwalo ogobayo ngemva kokukhishwa kwe-axle shaft.
Okubizwa ngokuthi i-full-floating half shaft kusho ukuthi i-half shaft ithwala i-torque kuphela futhi ayinaso isikhathi sokugoba.Uhlangothi olungaphakathi lwe-half shaft luxhunywe negiya eliseceleni elihlukile ngokusebenzisa ama-splines, kanti uhlangothi lwangaphandle lunepuleti le-flange, elihlanganiswe nehabhu lesondo ngamabholithi, futhi ihabhu lesondo lifakwa kwi-ekseli ngamarola amabili anamathephu. ama-bearings.Ngale ndlela, ukushaqeka okuhlukahlukene nokudlidliza emasondweni, kanye nesisindo semoto, kudluliselwa kusuka emasondweni kuya kuma-hubs bese kuya kuma-axles, ekugcineni athwalwa yi-axle housings.Ama-axle shafts avele adlulise i-torque isuka kumehluko iye emasondweni okushayela imoto.Kule nqubo, zombili iziphetho ze-shaft yesigamu zithwala kuphela i-torque ngaphandle kwanoma yisiphi isikhathi sokugoba, ngakho-ke kubizwa ngokuthi "ukuntanta okugcwele".Isithombe esilandelayo sibonisa ukwakheka nokufakwa kwe-half shaft entantayo egcwele yemoto.Isici sayo sesakhiwo ukuthi ihabhu lamasondo lifakwe ku-axle ngokusebenzisa ama-roller bearings amabili ane-tapered, isondo lifakwe kuhabhu lamasondo, amandla asekelayo adluliselwa ngqo ku-axle, futhi i-half-shaft idlula.Izikulufu eziyisishiyagalombili zinamathiselwe kuhabhu futhi zidlulisela itorque kuhabhu, zishayela isondo ukuze lijike.
I-half shaft egcwele ngokugcwele kulula ukuyihlakaza futhi ithathelwe indawo, futhi i-half shaft ingakhishwa kuphela ngokususa ama-bolts okulungisa afakwe ku-flange plate ye-half shaft.Kodwa-ke, isisindo sonke semoto ngemuva kokukhipha i-axle eyingxenye isekelwa izindlu ze-axle, futhi isengakwazi ukupaka phansi ngokuthembekile;okubi ukuthi isakhiwo siyinkimbinkimbi futhi izinga lezingxenye likhulu.Iwuhlobo olusetshenziswa kakhulu ezimotweni, futhi amaloli amaningi alula, aphakathi nendawo nasindayo, izimoto ezingekho emgwaqeni kanye nezimoto zabagibeli zisebenzisa lolu hlobo lwe-axle shaft.
Okubizwa ngokuthi i-semi-floating half shaft kusho ukuthi i-half shaft ayithwali nje i-torque, kodwa futhi ithwala umzuzu wokugoba.Uhlangothi lwangaphakathi lwe-axle shaft luxhunywe negiya le-axle elihlukile ngokusebenzisa ama-splines, ukuphela kwangaphandle kwe-axle shaft kusekelwe endlini ye-axle ngokusebenzisa i-bearing, futhi isondo lifakwe ngokuqinile ku-cantilever ekupheleni kwangaphandle kwe-axle. i-axle shaft.Ngale ndlela, amandla ahlukahlukene asebenza emasondweni kanye nezikhathi zokugoba eziholelayo zidluliselwa ngqo kuma-half shafts, bese kuthi ku-axle yezindlu zokushayela ngokusebenzisa ama-bearings.Uma imoto isebenza, ama-half shafts awagcini nje ngokushayela amasondo ukuze ajikeleze, kodwa futhi ashayela amasondo ukuze ajikeleze.Ukusekela isisindo esigcwele semoto.Ukuphela kwangaphakathi kwe-half shaft kuthwala i-torque kuphela kodwa hhayi umzuzu wokugoba, kuyilapho isiphetho sangaphandle sithwala kokubili i-torque kanye nomzuzu ogcwele wokugoba, ngakho-ke kubizwa ngokuthi "i-semi-floating".Isibalo esilandelayo sibonisa ukwakheka nokufakwa kwe-semi-axle entanta kancane yemoto.Isici saso sesakhiwo ukuthi isiphetho sangaphandle silungisiwe futhi sisekelwe ku-roller ene-tapered ene-tapered surface kanye nokhiye kanye nehabhu, futhi amandla e-axial angaphandle aqhutshwa i-roller eyi-tapered bear.I-Bearing, amandla e-axial angaphakathi adluliselwa ku-roller ene-tapered yolunye uhlangothi shaft uhhafu ngokusebenzisa isilayidi.
Isakhiwo sokusekela i-half-shaft esintantayo sihlangene futhi silula ngesisindo, kodwa amandla e-half-shaft ayinkimbinkimbi, futhi ukuhlakazeka nokuhlanganisa akulungile.Uma ama-axle shafts esuswa, imoto ayikwazi ukusekelwa phansi.Ngokuvamile ingasetshenziswa kuphela kumaveni amancane nasezimotweni ezincane ezinomthwalo wemoto encane, ububanzi besondo elincane kanye ne-asi ehlangene yangemuva, njengochungechunge oluvamile lwe-Wu ling nochungechunge lwe-Song hua jiang.
