uhlelo lokubhuleka. I-pedal yebhuleki iqine kakhulu noma ithambile. Lokhu kungabonisani?
I-braking system ingenye yezingxenye ezibaluleke kakhulu kunoma iyiphi imoto. Ukuhluleka kwezingxenye zayo kuyingozi kakhulu futhi kungaba nemiphumela emibi kakhulu. Isibonelo sokwehluleka i-pedal yebhuleki eqine kakhulu noma ethambile kakhulu, enciphisa ukusebenza kahle kwesistimu yokubhuleka.
Lapho umshayeli ecindezela i-pedal, iphampu iphampa uketshezi olusebenzayo ngamapayipi aqinile naguquguqukayo. Bese iya kuma-calipers, okuthi, ngenxa yamapiston ngaphansi kwengcindezi, cindezela iphedi ngokumelene ne-brake disc. Ucezu olubalulekile lwephazili luphinde lube yilokho okubizwa nge-Brake "servo booster", okuwumshini omncane odala i-vacuum eyengeziwe, eklanyelwe ukwandisa amandla okubhuleka. Ngaphandle kwayo, ngisho nokucindezela okuncane ku-pedal yebhuleki kungadinga umzamo omkhulu kakhulu kithi. Phela, ngezinye izikhathi umelana ngokweqile. Yini engase ibangele lokhu?
“Esinye sezizathu zokuvela kwalaba okuthiwa. I-pedal yebhuleki “eqinile” ingase ibangelwe uketshezi lwamabhuleki oludala noma olusezingeni eliphansi. Bambalwa abantu abakhumbulayo ukuthi i-hygroscopic, okungukuthi, imunca amanzi. Ngokuhamba kwesikhathi ne-mileage, ingaqongelela okuningi, okunciphisa ukusebenza kahle kwamabhuleki. Umshayeli uzwa lokhu ngenxa yokuqina okweqile kwebhuleki. Ngaphezu kwalokho, ukuba khona kwamanzi kubangela ukuthi uketshezi lulahlekelwe izici zalo zokulwa nokubola. Lesi ngesinye sezimbangela ezivame kakhulu zokugqwala kwe-brake hose ezimotweni ezindala, okungaba yingozi kakhulu njengoba ipayipi lingamane libhodloke. Ngenxa yalezi zenzakalo, uketshezi lwamabhuleki kufanele lushintshwe njalo ngemva kweminyaka emibili noma u-60 km, kuye ngokuthi yikuphi okuza kuqala,” kuchaza uJoanna Krenzelok, uMqondisi we-TMD Friction Services ePoland.
Esinye isizathu ukwehluleka kwepompo ye-vacuum, i.e. "Amaphampu vacuum". Iwumshini okhona kuzo zonke izinjini zikadizili ezishayela i-brake booster. Ezimotweni, kusetshenziswa izinhlobo ezimbili zayo - i-piston ne-volumetric. Ukwehluleka kwephampu yevacuum kungehlisa ukusebenza kahle kwesistimu yamabhuleki futhi kuvame ukubangelwa ukuguga kwepompo ngokwayo noma ukuvuza kukawoyela wenjini. Ngakho-ke, kufanelekile ukunakekela izinguquko zikawoyela ezifika ngesikhathi kanye nokusetshenziswa koketshezi olusezingeni eliphezulu. Enye imbangela ye-stiff brake pedal kungaba ama-piston anamathele kuma-brake caliper. Ngokuvamile, lesi simo siwumphumela wokuntuleka kokunakekelwa okufanele kwesistimu ye-brake lapho kushintsha izingxenye zayo. Kungenzeka futhi ukuthi izigqoko ze-rubber plunger ziguge ngenxa yokunqwabelana kwamanzi kule ndawo.

Uketshezi lwebhuleki oluphelile lungaba nomunye umphumela, okungukuthi. yenza i-pedal yebhuleki ithambe kakhulu. Ezimweni ezimbi kakhulu, isibonelo, ngenxa yokushisa ngokweqile kwesistimu, izovele iwele phansi. Uketshezi olumunca amanzi amaningi luba nephuzu eliphansi lokubila, ngakho kuyingozi kakhulu ukushayela okuguquguqukayo nokusetshenziswa njalo kwamabhuleki. Kulokhu, ngaphezu kokushintsha uketshezi, kuyadingeka ukufaka esikhundleni se-hoses ye-brake futhi uhlole ezinye izakhi zalesi simiso. Kungenzeka futhi ukuthi izinga le-brake fluid liphansi kakhulu ngenxa yokuvuza. Amaphutha ajwayelekile ahlanganisa ukuvuza kwesilinda okuyinhloko noma ukuvuza okuguquguqukayo noma okuqinile kwepayipi. Yini enye okufanele ikhunjulwe, ikakhulukazi endabeni yomhlangano wokucobelelana ngolwazi?
Isilinganiso sesevisi esibalulekile lapho ushintsha noma yiziphi izingxenye zesistimu yamabhuleki ukopha isistimu. Umoya osele oketshezini unciphisa umphumela wokubhuleka, ongabangela lokho okubizwa ngokuthi "i-soft brake". Uma wopha imoto nge-ABS, qala nge-master cylinder bese ulandela imiyalelo yokunakekela enikeziwe yale nqubo. Phinda lezi zinyathelo kuze kube yilapho kugeleza uketshezi olulinganayo ngaphandle kwamabhamuza omoya lusuka kuvalvu.
