Uma abantu bexoxa ngezithuthuthu ezinamasondo amathathu kanye namaloli amancane namaveni, bavame ukuthi le axle iyantanta ngokugcwele, nokuthi le axle iyantanta kancane. Kusho ukuthini ukuthi "i-full float" kanye nokuthi "i-semi-float" lapha? Ake siphendule lo mbuzo ngezansi.
Okubizwa ngokuthi "okugcwele okuntantayo" kanye "nokuntanta kancane" kubhekisela ohlotsheni lokusekelwa kokufakwa kwama-axle shaft ezimoto. Njengoba sonke sazi, i-half shaft iyi-shaft eqinile edlulisa i-torque phakathi kwe-differential namasondo okushayela. Uhlangothi lwayo lwangaphakathi luxhunywe ngegiya eliseceleni nge-spline, kanti uhlangothi lwangaphandle luxhunywe ne-hub yesondo lokushayela nge-flange. Njengoba i-half shaft idinga ukuthwala i-torque enkulu kakhulu, amandla ayo ayadingeka ukuba aphezulu kakhulu. Ngokuvamile, insimbi ye-alloy efana ne-40Cr, 40CrMo noma i-40MnB isetshenziselwa ukucima nokushisa kanye nokwelashwa kokucima okuvama kakhulu. Ukugaya, i-core inokuqina okuhle, ingamelana ne-torque enkulu, futhi ingamelana nomthwalo othile wokuthinteka, ongahlangabezana nezidingo zezimoto ngaphansi kwezimo ezahlukahlukene.
Ngokwezinhlobo ezahlukene zokusekela ze-half shafts, i-half shafts ihlukaniswe izinhlobo ezimbili: "i-full floating" kanye "ne-semi-floating". I-full-floating axle kanye ne-semi-floating axle esivame ukubhekisela kuzo empeleni zibhekisela ohlotsheni lwe-half-shaft. "I-Float" lapha ibhekisela emthwalweni wokugoba ngemva kokususwa kwe-axle shaft.
Okubizwa ngokuthi i-half shaft egcwele ukuntanta kusho ukuthi i-half shaft ithwala i-torque kuphela futhi ayithwali sikhathi sokugoba. Uhlangothi lwangaphakathi lwe-half shaft enjalo luxhunywe negiya eliseceleni elihlukile ngokusebenzisa ama-spline, kanti uhlangothi lwangaphandle lune-flange plate, eqiniswe ne-wheel hub ngama-bolts, kanti i-wheel hub ifakwe ku-axle ngama-roller bearings amabili athambile. Ngale ndlela, ukushaqeka nokudlidliza okuhlukahlukene kumasondo, kanye nesisindo semoto, kudluliselwa kusuka kumasondo kuya kuma-hub bese kuba kuma-axle, ekugcineni athwalwa yi-axle housings. Ama-axle shaft adlulisa i-torque kusuka ku-differential kuya kumasondo ukuze kushayelwe imoto. Kule nqubo, zombili iziphetho ze-half shaft zithwala i-torque kuphela ngaphandle kwesikhathi sokugoba, ngakho-ke ibizwa ngokuthi "i-full floating". Isithombe esilandelayo sibonisa isakhiwo nokufakwa kwe-full-floating half-shaft yemoto. Isici sayo sokwakheka ukuthi ihabhu lamasondo lifakwe ku-axle ngama-roller bearings amabili athambile, isondo lifakwe ku-wheel hub, amandla asekelayo adluliselwa ngqo ku-axle, bese i-half-shaft idlula. Izikulufo eziyisishiyagalombili zinamathiselwe ku-hub futhi zidlulisela i-torque ku-hub, ziqhuba isondo ukuthi lijike.
I-half shaft egcwele ukuntanta kulula ukuyihlukanisa nokuyishintsha, futhi i-half shaft ingakhishwa kuphela ngokususa amabhawodi okulungisa afakwe epuletini le-flange ye-half shaft. Kodwa-ke, isisindo sonke semoto ngemva kokususa i-half-axle sisekelwa yi-axle housing, futhi isengapakwa phansi ngokwethembeka; ububi ukuthi isakhiwo siyinkimbinkimbi futhi ikhwalithi yezingxenye inkulu. Luhlobo olusetshenziswa kakhulu ezimotweni, futhi iningi lamaloli alula, aphakathi nendawo kanye nasindayo, izimoto ezingaphandle komgwaqo kanye nezimoto zabagibeli zisebenzisa lolu hlobo lwe-axle shaft.
Okubizwa ngokuthi i-semi-floating half shaft kusho ukuthi i-half shaft ayithwali nje kuphela i-torque, kodwa futhi ithwala isikhathi sokugoba. Uhlangothi lwangaphakathi lwe-axle shaft enjalo luxhunywe negiya eliseceleni elihlukile ngokusebenzisa imigqa, ingxenye engaphandle ye-axle shaft isekelwa endlini ye-axle nge-bearing, futhi isondo lifakwe ngokuqinile ku-cantilever engxenyeni engaphandle ye-axle shaft. Ngale ndlela, amandla ahlukahlukene asebenza kumasondo kanye nezikhathi zokugoba ezivelayo adluliselwa ngqo kuma-half shaft, bese eyiswa endlini ye-drive axle ngama-bearings. Lapho imoto isebenza, ama-half shaft awagcini nje ngokuqhuba amasondo ukuze ajikeleze, kodwa futhi aqhuba amasondo ukuze ajikeleze. Ukusekela isisindo esiphelele semoto. Ingxenye engaphakathi ye-half shaft ithwala kuphela i-torque kodwa hhayi isikhathi sokugoba, kuyilapho ingxenye engaphandle ithwala kokubili i-torque kanye nesikhathi sokugoba esigcwele, ngakho-ke ibizwa ngokuthi "i-semi-floating". Isithombe esilandelayo sibonisa isakhiwo nokufakwa kwe-semi-floating semi-axle yemoto. Isici sayo sokwakheka ukuthi ingxenye yangaphandle iqinile futhi isekelwe kubheyaringi egobile enobuso obugobile kanye nokhiye kanye nehabhu, kanti amandla e-axial angaphandle aqhutshwa yibheyaringi egobile. Ubheyaringi, amandla e-axial angaphakathi adluliselwa kubheyaringi egobile yomunye umgodi ohlangothini nge-slider.
Isakhiwo sokusekela i-half-shaft esintanta kancane sincane futhi silula ngesisindo, kodwa amandla e-half-shaft ayinkimbinkimbi, futhi ukuhlukaniswa nokuhlanganiswa akuphazamisi. Uma imiphini ye-axle isuswa, imoto ayikwazi ukusekelwa phansi. Ngokuvamile ingasetshenziswa kuphela kumaveni amancane nezimoto ezilula ezinomthwalo wemoto encane, ububanzi obuncane besondo kanye ne-axle ehlanganisiwe yangemuva, njengochungechunge oluvamile lwe-Wu ling kanye nochungechunge lwe-Song hua jiang.
