I-ekseli yangemuva i-Heavy Duty Truck AC16 uhlobo lwe-parallel duplex drive axle, i-ekseli ithatha igobolondo le-asi le-axle elikhulu eliphambanayo, futhi ubukhulu bethoni obuthwele i-asi eyodwa bungamathani angu-16. I-axle ye-Howo 7 yokulahla iloli esindayo isebenzisa ukwehla kwezinyathelo ezimbili Isakhiwo esinesilinganiso sejubane esingu-5.45, kanye ne-decelerator ephakathi ye-helical bevel gear kanye ne-wheelside planetary decelerator yenza ukwehla okuphindwe kabili ukuze kwandiswe i-torsion, futhi ngasikhathi sinye kungathuthukisa ukucaciswa komhlaba kwe-axle.
Womabili ama-asi angaphambili eloli le-Howo 7 heavy duty duty duty ama-asili angaphambili ohlobo lwe-HF9 abheke phansi e-Heavy Duty Truck, anomthwalo we-asi elilodwa lamathani angu-9, ahambisana namasondo ensimbi angu-10-bolt kanye no-12.00R20 uhlobo lwamasondo ensimbi ohlobo lwamaloli okwakha.I-sub-pump yebhuleki ihlinzekwa ngabakwa-Wilburco ukuze uthole ukuphepha okuthembekile kokubhuleka.Iloli lonke lithatha amabhuleki ezigubhu kanye nama-air brake air chambers, kanti ububanzi bezicathulo zokushayisana kwamabhuleki kwi-axle yangemuva bungafinyelela ku-220mm, kanti umfutho womoya wamabhuleki ngu-0.8Mpa, nokusebenza kahle kwamabhuleki.Imvelo yendawo yokwakha yimbi kakhulu, inothuli, ikhwalithi yomoya ephansi, ngakho-ke imoto ithatha izihlungi zomoya eziphindwe kabili, ukungena emoyeni kusihlungi somoya sephepha kuzohlungwa ngaphambi kwesihlungi somoya samafutha, ukuze kuqinisekiswe ukuthi injini iqhaza ekushisweni komoya kuhlanzekile.
