Off-highway lirthei a niwheel rim a awm bawkhun rei tak hman hnuah chhiatna chi hrang hrang a nei thei. Accident a awm loh nan lirthei khalh hmain rim te enfiah hmasa phawt ang che.
I. Thil chhiatna chi hrang hrang
Deformation (deformation) a ni
Radial bulge emaw dent emaw:Rim roundness-a hmuh theih loh, lungpui nena high-speed impact avanga lo awm fo thin.
Rim tawp hmai pangngai lo:Rim edge leh tire inkar gap hi rotation laiin a inthlak thin. Hei hi overloading, braking nghal vang emaw, installation laiin force inthlau lutuk vang emaw a ni thei.
Rim edge emaw bead seat area-a indentation awmte chu:Hard object impact avanga lo awm, lunghlu laihchhuahna hmun emaw, in sakna hmuna lungpui tamna hmuna hmuh fo thin.
Cracks a awm
Rim wall emaw spoke emaw-a linear crack awmte chu:A tir lamah chuan a te a, hriat harsa tak a ni a, mahse hman chhunzawm zel chuan a zau zau zel thung.
Weld joint emaw hub connection area-a crack awmte chu:Stress concentration leh vibration rei tak avanga lo awm a ni.
Bolt hole vel radial emaw circular emaw crack awm:Bolt torque inang lo emaw, assembly leh disassembly nawn leh avanga stress concentration thlentu atanga lo chhuak a ni.
Ha
Tyre bead contact area-a a chhe emaw, a hring emaw a awm chuan:Fitting clearance a tipung a; a tlangpuiin tire lakchhuah fo vang te, tire size dik lo vang te, sand/gravel abrasion vang te a ni.
Rim kil thinning emaw dulling emaw, curling:Kawngpui sira thil dang emaw, lungpui emaw nena hun rei tak- inhnaih avanga lo awm.
Bolt holes te chu wear emaw ovalization emaw a nih chuan:Bolt fit loose a thlen a, a tam zawk chu disassembly nawn fo emaw, bolt specification dik lo vang emaw a ni.
Corrosion a awm
Chemical hmanga hnim hring (corrosion): 1.1.Acid emaw alkaline solution nena inzawm chuan surface corrosion leh peeling a thlen a, material chakna a ti tlem a ni.
Hmun lum takah rusting: 1.1.Metal leh bawlhhlawh inkara oxidation hian rust a thlen a, rim chu a thim zauh zauh thin.
Salt corrosion a awm chuan:Tuipui kama awm emaw, de-icing atana kawngpui chi hmanna hmunah emaw, chi (salt deposit) hian corrosion process a ti chak hle.
II. Hriselna atana hlauhawm awm thei
Driving himna atana hlauhawm direct: 1.1.
Bead seat chhe tawh, rim deformation, emaw crack emaw hian tire-to-rim fitment tha lo a thlen thei a, chu chuan tire a tikehsawm nghal thei a, a bik takin kawngpui hnim hring emaw, steering lai emaw a ni.
Wheel a inthlak danglam thin:
Lateral deformation hian wheel oscillation a thlen thei a, chu chuan steering deviation emaw braking laiin fishtailing emaw a thlen thei a ni.
Tyre load inang lo tak tak:
Rim deformed emaw worn emaw hian tire stress inang lo a thlen a, chu chuan localized pressure nasa lutuk a thlen a, high-speed emaw heavy-load driving laiin tire blowout risk a tipung bawk.
III. Hriselna atana hmalakna
1. Hnathawh dan tlangpui
Mine emaw, sakna hmun emaw ang chi kawngpui laih loha lirthei khalh laiin lung emaw, khur emaw hmanga chak taka inhnaih loh tur; harsatna awmte chu a hmain inthiarfihlim rawh.
Hun kal zelah rim stress nasa lutuk lo turin lirthei rated load chhungah hna thawk rawh.
Tire leh bolt specification inmil hmang rawh; torque tarlan angin bolt te chu a rualin tikhauh rawh; tire lakchhuah fo emaw, chak taka lakchhuah emaw loh tur.
2. Inspection neih fo
Trip apiangin rim-te chu deformation, crack, rust, leh loose bolts te enfiah hmasa phawt ang che; tire tight-to-rim fit taka awm ngei ngei tur a ni.
Thla 3 emaw km 5,000 danah professional hmanrua hmangin rim roundness leh lateral runout enfiah thin tur; micro-crack te chu a hmain hriat theih a ni.
Deformation tlemte chu siamthat theih a ni a; rust paih la, a chhiat belh loh nan corrosion emaw wear emaw tenau te hmuh a nih chuan repaint nghal rawh.
3. Thil tih belh tur
Driving zawhah rim chunglam atanga leilung, chi leh chemical awmte chu silfai la, a vawt reng tur a ni.
Corrosive emaw high{0}}impact environment-ah (eg, tuipui kama hmun, mine)-ah chuan wear- leh corrosion-resistant alloy rim hmang la emaw, protective coatings hmang fo ang che.
Ram pum tehfung zawm thei rim hmang la; thil siam thar, a hniam zawk, a inmil lo emaw chu pumpelh rawh.
Weld rim tan chuan weld quality enfiah la, weld seam chhia nei product te chu pumpelh rawh.
