Vanhu pavanokurukura nezvemidhudhudhu ine mavhiri matatu nemamwe marori madiki nemaveni, vanowanzoti ekisi iyi iri kuyerera zvizere, uye ekisi iyoyo iri kuyerera zvishoma. Zvinorevei kuti "full float" uye "semi-float" pano? Ngatipindurei mubvunzo uyu pazasi.
Zvinonzi "full-floating" uye "semi-floating" zvinoreva rudzi rwekutsigira mounting ye axle shafts dzemotokari. Sezvatinoziva tese, half shaft ishaft yakasimba inotumira torque pakati pe differential nema drive wheels. Rutivi rwayo rwemukati rwakabatana ne side gear kuburikidza ne spline, uye divi rekunze rakabatana ne hub ye drive wheel ne flange. Sezvo half shaft ichida kutakura torque yakakura kwazvo, simba rayo rinodiwa kuti rive rakakwirira kwazvo. Kazhinji, alloy steel yakadai se 40Cr, 40CrMo kana 40MnB inoshandiswa pakudzimisa nekudziya uye high-frequency quenching treatment. Kukuya, core ine kusimba kwakanaka, inogona kumira torque yakakura, uye inogona kumira mutoro wakakura, uyo unogona kusangana nezvinodiwa nemotokari pasi pemamiriro akasiyana-siyana.
Zvichienderana nemhando dzakasiyana dzekutsigira dzehafu shafts, hafu shafts dzakakamurwa kuita mhando mbiri: "full floating" uye "semi-floating". Axle yakazara floating nehafu-floating axle yatinowanzo taura nezvayo zvinoreva rudzi rwehafu-shaft. "Float" pano inoreva mutoro unokotama mushure mekunge axle shaft yabviswa.
Iyo inonzi full-floating half shaft zvinoreva kuti half shaft inongotakura torque chete uye haina nguva yekukotama. Rutivi rwemukati rwehafu shaft yakadaro rwakabatana negiya rekusiyana kuburikidza ne splines, uye divi rekunze rine flange plate, iyo yakasungirirwa ne wheel hub nema bolts, uye wheel hub yakaiswa pa axle kuburikidza nema tapered roller bearings maviri. Nenzira iyi, kuvhunduka kwakasiyana-siyana uye kuzununguka kumavhiri, pamwe nehuremu hwemotokari, zvinotumirwa kubva kumavhiri kuenda kuma hubs uye zvinozoenda kuma axles, ayo pakupedzisira anotakurwa ne axle housings. Axle shafts inongotumira torque kubva ku differential kuenda kumavhiri kuti ityaire mota. Mukuita uku, magumo ese ehafu shaft anongotakura torque pasina nguva yekukotama, saka inonzi "full floating". Mufananidzo unotevera unoratidza chimiro uye kuiswa kwe full-floating half-shaft yemotokari. Chimiro chayo ndechekuti hub yevhiri yakaiswa pa axle kuburikidza nemabheyaringi maviri ane tapered roller, vhiri rakaiswa pa wheel hub, simba rinotsigira rinotumirwa zvakananga ku axle, uye half-shaft inopfuura nepakati. Skuruu sere dzakanamirwa pa hub uye dzinotumira torque ku hub, zvichifambisa vhiri kuti ritenderere.
Hafu yemuchina inoyangarara iri nyore kupatsanura nekutsiva, uye hafu yemuchina inogona kubviswa chete nekubvisa mabhoti ekugadzirisa akaiswa paflange plate yehafu yemuchina. Zvisinei, huremu hwese hwemota mushure mekubvisa hafu yemuchina hunotsigirwa nehomwe yemuchina, uye inogona kugadzikwa pasi zvakachengeteka; dambudziko nderekuti chimiro chayo chakaoma uye mhando yezvikamu zvayo yakakura. Ndiyo mhando inonyanya kushandiswa mumota, uye marori mazhinji akareruka, epakati neanorema, mota dzemumugwagwa nemota dzevafambi dzinoshandisa rudzi urwu rwemuchina wemuchina.
Iyo inonzi hafu-floating half shaft zvinoreva kuti hafu shaft haingori chete ine torque, asiwo ine nguva yekukotama. Rutivi rwemukati rwe axle shaft yakadaro rwakabatana ne differential side gear kuburikidza ne splines, mugumo wekunze we axle shaft unotsigirwa pa axle housing kuburikidza ne bearing, uye vhiri rakaiswa zvakasimba pa cantilever kumucheto wekunze we axle shaft. Nenzira iyi, masimba akasiyana-siyana anoshanda pamavhiri uye nguva dzekukotama dzinobuda zvinotumirwa zvakananga ku half shafts, uye zvino kuenda ku drive axle housing kuburikidza nema bearingers. Kana mota ichifamba, half shafts haingotyai mavhiri kuti atenderere, asiwo inotyaidza mavhiri kuti atenderere. Kutsigira huremu hwakazara hwemotokari. Mugumo wemukati we half shaft unongotakura torque kwete nguva yekukotama, nepo mugumo wekunze unotakura torque uye nguva yekukotama yakazara, saka inonzi "semi-floating". Mufananidzo unotevera unoratidza chimiro uye kuiswa kwe semi-floating semi-axle yemotokari. Chimiro chayo ndechekuti mugumo wekunze wakasimba uye wakatsigirwa pabearing yeroller ine tapered surface nekiyi ne hub, uye simba rekunze re axial rinofambiswa nebearing yeroller ine tapered. Bearing, simba remukati re axial rinoendeswa kune bearing yeroller ine tapered yerimwe divi re half shaft kuburikidza ne slider.
Chimiro chekutsigira hafu yeshaft chinoyangarara zvishoma nezvishoma uye chakareruka, asi simba rehafu yeshaft rakaoma, uye kupatsanurwa nekusanganiswa kwacho hazvina kunaka. Kana shaft dze axle dzikabviswa, mota haigone kutsigirwa pasi. Kazhinji inogona kushandiswa chete kumaveni madiki nemotokari diki dzine mutoro wemotokari diki, dhayamita diki yemavhiri uye rear integral axle, senge common Wu ling series neSong hua jiang series.
