Unogada Underride for iilori: inkcazo kunye neemfuno

unogada Underride yi isixhobo buyafuneka xa iilori zisebenze. Elinye igama ngolwimi abanini moto "yezihlangu" ukususela imilo kwabo okufana ngayo: unxantathu ekunene-engile egqithe nge begoba. Xa uyeka umqhubi ngokuqhelekileyo kwenza imoto kwi kusisithintelo manual, kodwa kwezinye iimeko, kunokunganeli kusisithintelo yokupaka.

Ngokomzekelo, xa kokumisa ethambekeni kwenduli uya kufuna ezinye umlinganiselo yokhuseleko - wabasiki underride, ebonelela lokugcina isithuthi kwindawo utyekelo indlela wendlela. Uyakwazi ukumelana umthwalo omkhulu, ngoko oko kuza kuba iimoto kunye nezigadla.

unogada Underride for iilori kufuneka ukuhlangabezana nemigangatho ethile umgangatho, kufuneka isiqinisekiso. Ngoncedo lwabo kulula ukunqanda intshukumo esingalindelekanga kulo matshini. Okwangoku, ugxininiso kufuneka uqiniseke bonke abanini imoto.

chocs design

Imigaqo imisela ukusetyenziswa abanini isithuthi ukuba kusoloko chocks esinamavili iilori. Ezi mfuno kusebenza oku kulandelayo: bamele babe uyilo ukuba nayo yonke imigangatho, ngokunjalo ukumelana imithwalo eliphezulu. Umqhubi kufuneka athobele imiqathango ethile:

• Le zokumisa kufuneka ubudeki ivili ofanelekileyo.
• Indawo iza kuhamba.
• Indawo yomqeshi emotweni (kwempahla kufuneka ibe phezu emzimbeni okanye erhuqwayo).

Ukuyibetha ngoyaba le meko kusongela isohlwayo - ifayini enzima

Amaxesha amaninzi chwetheza 2 chocks uyilo: uhlobo eqhelekileyo yonxantathu kunye yokukhwabusha-ngohlobo abutment ye nesinqumka. Materials, ezakha unogada underride ngenxa iilori nalo ezimbini. Okokuqala, kukho ixesha elide kakhulu, ezikumgangatho ophezulu kwaqinisa zeplastiki. Okwesibini, i intsimbi kwalenza. Kuba okokuqala ngesidanga umthwalo 800 kg iqala kunye kugudiswa kwi 6500 kg. Kuba Ngokomzekelo yesibini ubuncinane amandla ekhona 1750 kg kwaye ubuninzi - 6500 kg.

Kubonakala ukuba inzuzo ngentsimbi kuya kuhamba khona, kodwa kukho umda. Xa ezithutha olunokutsha, ulwelo olunokutsha, nezinto ukusetyenziswa kuphela ukuba anokuthintela zeplastiki ngokhuseleko ngomlilo. Ukuba ilori uthutha izinto evakalala ezifana nesanti, ngoko advantageously usebenzise abutment sentsimbi, ekubeni unako ukungena izinto ezincinane nempahla umsantsa phakathi nensimbi yaye kuziindleko, ukuba kwimeko zeplastiki kungakhokelela ekubeni isithuthi emva ngenxa uxhathiso kwanciphisa abutment lomlingani kunye endleleni.

bavimbe zeplastiki

Impazamo kakhulu xa uthenga unogada underride ngenxa iilori, yenza wabaqalayo kungekho amava. Ukuba uthenga iimveliso zeplastiki nzima, kodwa bubuthathaka. Ezi zokumisa uwaphule ngokukhawuleza xa yahlaselwa ivili. Kwakhona, kukho imeko apho umqhubi Ilibale phambi iqhubheka intshukumo ukususa kubo, ngoxa kwimeko ngamaqhekeza amancinci kuphela zeplastiki kuhlala kuzo.

ukuvimba zeplastiki zibuthathaka kakhulu, siphila ixesha elifutshane, ngoko kuthenga kubo akunconywa, ukuba kamva usebenzisa kwiimeko ezinzima.

irabha

Kakhulu ixesha elide kunokuba yeplastiki, ivili irabha swi ukuba iilori.

lencazelo, Ngokutsho abathengi abaninzi, ngokufanayo leyinene. Ngerabha eyeka - ukhetho elungileyo kakhulu kuthenga, zenziwe iirubber elide nzima, ukuba agidime phezu kwabo, abayi kuyaphula, ngokungafaniyo yeplastiki. Kukho iintlobo ezininzi ezahlukeneyo iimveliso ngerabha, kodwa umgangatho konke malunga efanayo - okulungileyo.

metal

Eside kakhulu onobuhle thaca lo ugxininiso underride ilori metal. Metal zinezibonelelo njenge uthotho okanye inani nezingalunganga kuthelekiswa betye zeplastiki kunye zerabha. Okokuqala, uncedo engundoqo abutment sisinyithi na ihlala zabo. Kuyinto amaxesha amaninzi ngakumbi amandla irabha okanye iplastiki. Okwesibini, kuyenzeka ukuba ukusebenzisa uguqulelo eyomeleleyo enamavili, nto leyo kakhulu ngokoqobo kakhulu kuyaphi kunezixhobo kwezinye izinto; ukhetho yokusonga neyendlu isithuba encinane kakhulu yomqeshi kuthelekiswa ne eqhelekileyo.

Luncedo maxa wambi isitshixo xa ukhetha i xenga olubi, eyaphula imithetho yokugcina imveliso ligutyungelwe mhlwa kunye aphulukane inokuthenjwa elide. Emva koko sebenzisa unogada underride ngokuba iilori singakhuselekanga.

izidingo

Ngokutsho imithetho ethile, chocks ivili kufuneka ithobele ezi mfuno zilandelayo:

1. bomthwalo, ekufuneka ukumelana izingxi, isiqingatha le ubunzima iyonke kwesithuthi.
2. Ukuba inshorensi ufakelo olwandeleyo kweevili.
3. Kufuneka ngaphandle nayiphi slippage kunokwenzeka kwi ethe endleleni.
4. Kufuneka ube umbala uphawu: obomvu,-orenji okanye omthubi.

Imiqathango edweliswe ngezantsi ekufuneka ilandelwe xa chocks zisetyenziselwa iilori. Iimfuno SDA ngokumlandela:

1. Kwizithuthi ezinobunzima ngaphezulu kwe-3.5 m (ngokuba iilori) ne-5 m (ibhasi) kufuneka asebenzise abutments ubuncinane ezimbini.
2. Ukufunyanwa kwe iilori abanobunzima ngaphezu 3.5 tonnes kunye neebhasi anobunzima ngaphezulu kwe-5 kufuneka siquke ubukho zokumisa ubuncinane ezimbini.
3. Baya kufuneka lufikeleleke lula, kodwa kufuneka ilungiswe ngokuqinileyo ukuba ukulahlekelwa.
4. Kuba iinqwelwana yamahashe uyilo kufuneka ajongane operable waqhekeza kunye ivili chocks.

isiphelo

Xa zonke ezi mfuno zilapha ngasentla kuyahlangatyezwana, le chocks bavumelekile ukuba isebenze. Ukongeza, ngaphambi kokuba aye intengiso kufuneka zihlolelwe kwalo. Ngoko ke, umthengi ukhetho ivenkile kufuneka kuwa phezu imveliso esemgangathweni eya simkhonze ixesha elide.
