Rail Lateral Hnav yog dab tsi thiab Vim Li Cas Nws Tseem Ceeb?
Lateral hnav - feem ntau hu ua sab coj los yog ntsuas - kaum hnav - yog qhov poob ntawm cov hlau ntawm qhov ntsuas sab ntawm lub taub hau tsheb ciav hlau qhov twg lub log flange rubs thaum nkhaus. Ib qho me me ntawm sab hnav yog qhov qub thiab raug tso cai rau hauv kev txwv kev saib xyuas, tab sis thaum hnav dhau qhov txwv lub arc profile ntawm lub taub hau rail raug puas tsuaj. Qhov chaw sib cuag ntawm lub log flange thiab kev tsheb nqaj hlau raug txo los ntawm ntau dua 30%, yog li kev sib cuag kev ntxhov siab nce siab thiab kev taw qhia quab yuam ntawm lub log thiab tsheb ciav hlau ntog. Ntawm qhov nkhaus lub tsheb ciav hlau lub zog centrifugal tsis tuaj yeem sib npaug, ua rau muaj kev pheej hmoo ntawm lub log flange nce thiab derailment. Sab hnav kuj ua rau lub ntsej muag ntse uas ua rau lub ntsej muag hnav, ua rau lub log flange thiab tsim kom muaj tus kheej - txhawb nqa lub voj voog ntawm kev tsheb nqaj hlau, flange hnav thiab kev taw qhia tsis ua haujlwm.
Yog vim li cas qhov txwv yog 17mm ntawm Plain Lines thiab 10mm ntawm High -Speed Lines
Qhov txawv yog tswj hwm los ntawm lub tsheb ciav hlau ceev thiab lub log -rail dynamic teb. High- cov tsheb ciav hlau ceev txhim kho cov centrifugal loj hauv kev nkhaus thiab nyob ntawm lub log meej- kev taw qhia kev tsheb ciav hlau; txawm tias ib qho me me ntawm sab hnav ntsuas txo cov kev taw qhia kev nyab xeeb. Qhov sib txuam precision ntawm lub log flange thiab cov tsheb ciav hlau lub taub hau profile kuj tseem nruj dua rau siab -ceev Tshuag, yog li ib zaug hnav tshaj li ntawm 10mm qhov sib txawv ntawm mating yog puas thiab lub log -rail cuam tshuam intensifies. Cov kab dawb ua haujlwm ntawm qhov qis qis nrog lub zog centrifugal me, thiab lub log profiles zam kev hnav ntau dua, yog li qhov tso cai txwv tau teem rau ntawm 17mm. Nyob rau hauv ob qho tib si cov kev txwv no tau sau rau hauv txoj cai tswj xyuas kev khiav tsheb thiab tsim ib thaj tsam ntawm kev sib tsoo thiab kev hloov tsheb tam sim.
Ua haujlwm ntawm 80% ntawm Qhov Kev Txwv: Lub Chaw Ceeb Toom
Thaum sab coj mus txog 80% ntawm qhov txwv - 13.6mm ntawm cov kab dawb thiab 8mm ntawm siab - kab nrawm - txoj kev tsheb ciav hlau tau nkag mus rau thaj tsam ceeb toom txaus ntshai thiab kev tiv thaiv yuav tsum pib txawm tias tus nqi tseem nyob hauv tus qauv. Plaub qhov kev ntsuas yog kev coj ua qauv:
Kev ntsuas hnav txhua lub lim tiamlos saib xyuas tus nqi ntawm kev txhim kho hnav thiab kwv yees thaum twg qhov kev txwv yuav ncav cuag.
Curve gauge adjustment- nqaim qhov ntsuas ntawm qhov nkhaus nyob rau hauv tus qauv kam rau ua kom txav qhov chaw tiv tauj mus rau qhov tsis hnav ntawm lub taub hau tsheb ciav hlau.
Log -rail lubricationntawm lub ntsej muag gauge kom txo cov kev sib txhuam coefficient thiab qeeb tus nqi hnav.
Sab sib tsoontawm txoj kev tsheb ciav hlau los kho ib feem ntawm lub taub hau profile thiab txuas ntxiv lub neej ntawm kev tsheb nqaj hlau.
Txoj Kev Phem Phem Ntawm Kev Hnav Tsis Ncaj Ncees
Kev hnav tsis sib xws - hnyav rau ntawm ib qho kev sib tw ntawm ob khub thiab me ntsis ntawm lwm qhov - yog qhov txaus ntshai dua li hnav khaub ncaws vim nws cuam tshuam kev taug qab geometry. Qhov hnav ntawm txoj kab nruab nrab ntawm txoj kab hloov pauv, ua qhov hloov pauv hloov pauv, thiab qhov tshwm sim ntawm qhov ntsuas qhov sib txawv tshaj qhov txwv tau nce ntau dua 50%. Lub tsheb ciav hlau hnyav hnyav kuj qaij me ntsis hauv qab thauj khoom, uas tuaj yeem thawb cov theem ntawm kev ua siab ntev thiab tsim lub log-squeal thiab corrugation txaus ntshai. Lub asymmetry hloov lub lateral tawv ntawm txoj kev, hloov qhov zoo superelevation nyob rau hauv lub nkhaus, thiab degrades caij zoo. Ntev - lub sij hawm hnav tsis sib xws distors txoj kev tsheb ciav hlau thiab ua rau cov nqi kho mob, yog li ob peb txoj hlua nrog sib txawv hnyav hnyav yuav tsum raug kho raws li kev sib tsoo ceev los yog hloov rooj plaub, tsis yog ib qho hnav xwb - rooj plaub.
Yuav Ua Li Cas Ntsuas Sab Hnav Kom Zoo Ntawm Qhov Chaw
Sab hnav yuav tsum tau ntsuas nrog ib tug tshwj xeeb rail hnav gauge, tsis yog ib tug steel daim kab xev los yog improvised caliper. Lub ntsuas ntsuas yog positioned nrog nws qhov chaw ntawm lub ntsej muag tiv thaiv sab saum toj thiab ntsuas sab ntawm lub taub hau tsheb ciav hlau, thiab ntsuas ntsuas tau muab tso rau ntawm qhov tob tshaj plaws hnav, feem ntau ntawm lub taub hau lub puab tsaig. Kev nyeem tau raug coj los ntawm ob sab hauv thiab sab nraud ntawm txoj kab nkhaus ntawm peb qhov chaw tseem ceeb - nkhaus vertex, nkhaus pib thiab nkhaus kawg - thiab qhov phem tshaj tus nqi tswj qhov kev txiav txim. Kev ntsuas kom raug daws 0.1mm thiab siv cov ntaub ntawv ruaj khov, uas qhov ntsuas tsis tuaj yeem muab tau. Kev ntsuas qhov yuam kev ntawm tus nqi txwv tsis tuaj yeem lees txais vim tias nws tuaj yeem tso cai rau txoj kev tsheb ciav hlau tsis zoo nyob hauv txoj kev los yog quab yuam hloov ntxov ntawm lub suab rail.
Cov lus nug nquag
Sab hnav puas tuaj yeem kho yam tsis tau hloov txoj kev tsheb ciav hlau?
Sab hnav hauv qhov txwv tuaj yeem hais los ntawm kev sib tsoo profile thiab ntsuas -lub ntsej muag lubrication kom qeeb hnav ntxiv. Thaum qhov kev txwv dhau lawm, kev kho vuam ntawm lub kaum ntse ntse yog ua tau ntawm qee qib tab sis yuav tsum muaj kev tsim nyog kho tsheb ciav hlau; feem ntau cov tsheb ciav hlau hloov.
Ntev npaum li cas yuav tsum sab hnav yuav ntsuas ntawm txoj kev nkhaus?
Ntawm cov kab tsheb thauj khoom hnyav hnyav, kev ntsuas feem ntau yog ib feem ntawm kev soj ntsuam xyuas ib txwm; nyob rau hauv 80% ceeb toom cheeb tsam qhov zaus nce mus rau ib lub lim tiam, thiab automated track recording tsheb ntxiv cov phau ntawv nyeem.
Vim li cas qhov siab - khiav ceev siv qhov kev txwv me dua li cov kab thauj khoom?
High- cov khoom ceev ceev muaj lub log nruj dua- kev tsheb ciav hlau tshem tawm thiab kev xav tau ntau dua, thiab cov kev hloov pauv me me ua rau muaj kev cuam tshuam loj ntawm 250-350 km / h. Cov kab tsheb thauj khoom zam hnav ntau dua vim tias kev xav tau nrawm thiab kev taw qhia qis dua.
Dab tsi yog qhov txawv ntawm sab hnav thiab ntsug lub taub hau?
Sab hnav tshem tawm cov hlau los ntawm lub ntsej muag lub ntsej muag ntawm lub taub hau thiab ntsuas kab rov tav ntawm lub puab tsaig taub hau; ntsug taub hau hnav yog ntsuas downwards los ntawm lub crown. Ob leeg tau taug qab sib cais thiab txhua tus muaj nws tus kheej txwv nyob rau hauv cov cai tswj xyuas.
Puas yog lub log -rail lubrication npog qhov hnyav hnyav?
Lubrication txo cov kev sib txhuam coefficient thiab slows hnav, tab sis nws tsis restore hnav profile. Nws yuav tsum tau siv ua ke nrog kev ntsuas thiab kev sib tsoo - tsis yog qhov hloov pauv kom ua tau raws li qhov txwv tsis pub hnav.
