Ukugqiba iityhubhu zentsimbi ezingenamthungo ulwahlulo olubanzi lwezicelo:
Ukuhlelwa kokugqiba umbhobho wentsimbi engenamthungo kusetyenziswa ngokubanzi:
I-1, Ukugqiba ngesakhiwo sentsimbi esingenamthungo iibhubhu zensimbi ezingenamthungo kwisakhiwo ngokubanzi kunye nesakhiwo soomatshini.
I-2, Ukuhanjiswa kwamanzi kunye nombhobho wensimbi ongenamthungo ogqiba iityhubhu zentsimbi ezingenamthungo zisetyenziselwa ukuhambisa amanzi, i-oyile, igesi kunye nolunye ulwelo.
I-3, ibhoyila yoxinzelelo oluphantsi noluphakathi ukugqibezela umbhobho wentsimbi engenamthungo isetyenziselwa ukwenziwa kwebhoyila eyahlukahlukeneyo ephantsi kunye nephakathi yoxinzelelo lwebhoyila, imibhobho yamanzi abilayo kunye netyhubhu yebhoyila eshushu kakhulu, umbhobho we-opium, umbhobho omncinci kunye ne-arch yezitena esebenza kakhulu kwi-carbon structural. intsimbi kunye nokubanda okutsalweyo (eqengqiwe) umbhobho wentsimbi ongenamthungo.
I-4, ibhoyila yoxinzelelo oluphezulu yokugqiba iityhubhu zentsimbi ezingenamthungo zokwenza umgangatho ophezulu wekhabhoni yentsimbi kunye noxinzelelo olungaphezulu lwamanzi ityhubhu yebhoyila yokufudumeza umphezulu ngentsimbi, intsimbi yealloy.
I-5, izixhobo zesichumisi seMichiza, uxinzelelo oluphezulu lusetyenziswa kwiqondo lokushisa elisebenzayo -40 ~ 400 ℃, uxinzelelo olusebenzayo lwensimbi ephezulu ye-carbon structural steel kunye ne-alloy steel 10 ~ 30Ma yezixhobo zeekhemikhali kunye neetyhubhu zensimbi ezingenamthungo.
I-6, i-axle ye-axle ye-Automobile casing ene-axle ye-axle ye-axi yemoto kunye ne-axle ye-axle ye-axle ye-axle yokuqhuba iityhubhu ezikumgangatho ophezulu wekhabhoni yesakhiwo sentsimbi kunye ne-alloy yesakhiwo sentsimbi eshushu-eqengqelekayo iityhubhu zentsimbi ezingenamthungo.
I-7, I-injini ye-diesel enombhobho woxinzelelo oluphezulu kukudala inkqubo yokutofa kwedizili yeetyhubhu ezibandayo ezingenamthungo.
I-8, i-Hydraulic kunye ne-pneumatic cylinder ene-diameter echanekileyo yangaphakathi ngumenzi we-hydraulic kunye ne-pneumatic cylinder ene-cold-drauled okanye i-cold rolled precision iityhubhu zetsimbi ezingenamthungo ezinobukhulu obuchanekileyo.
I-9, ukuchaneka okuqengqelekayo okubandayo okanye okubandayo kusetyenziselwa ukuchaneka okuphezulu kobume bomatshini, izixhobo zehydraulic kunye nokugqiba okuhle komphezulu obandayo otsalwayo okanye obandayo oqengqelekayo ochanekileyo.Sebenzisa umbhobho ochanekileyo ongenamthungo wokuvelisa umatshini okanye izixhobo ze-hydraulic, unokunciphisa kakhulu ixesha lomatshini, ukuphucula ukusetyenziswa kwezinto, kunye nokunceda ukuphucula umgangatho wemveliso.

Ukugqiba imibhobho yentsimbi engenamthungo - ekhuselekileyo, ethembekileyo, impilo yokusingqongileyo, efikelelekayo, imibhobho enodonga olucekethekileyo kunye nemibhobho emitsha ethembekileyo, egqibezela intsimbi engenamthungo - inombhobho ongcono kakhulu ongenakubuyiselwa, iya kuba bubuNjineli obukhulayo kwaye ukusetyenziswa okungaphezulu kuya kuthandwa ngakumbi.
