Ukuguquka kuyawa xa ucinezela i-brake: izizathu ezinokwenzeka, izisombululo kunye neziphakamiso

Imoto yinkqubo eninzi yokusebenza apho usebenziso oluchanekileyo nolunxibeleleneyo lwazo zonke iinkqubo kunye ne-node nganye kubalulekile. Ukuphazamiseka okungafaniyo kunye nokuchithwa kweminye yeenkcukacha kunokukhokelela ekuphuculweni kwe-algorithm ecacileyo yokusebenza kwezinye iisistim. Akuqhelekanga ukuhlangabezana neemeko apho iinguqulelo ziwela xa i-brake igxininiswa. Xa le nkathazo ihlala ijika kumatshini ombane. Ukuba ngexesha lokuqhaqhaqhaqhaqhaqa qalisa ukubhukuda ijubane, ungalindeli de ivele imoto. Kungekudala emva koko, injini iya kuqala ukududla ngamandla kunye ne-stall. Ngendlela, ingxaki iyona kuphela kwiinjini zepetroli.

Kungenzeka isizathu

Ukuguquka kuyawa xa i-brake igxininiswa ngenxa yeempazamo ezahlukeneyo kwi- booster breaker. Ukufumanisa isizathu ngokuchanekileyo, kuyimfuneko ukwazi ukuba i-node enikeziwe ihlelwe kanjani. Ukwazi indlela oku kusebenza ngayo, kwaye ukuhlangabezana nokuphazamiseka okunjalo, kuya kuba lula ukusombulula ingxaki.

Vula umlenzeli

Ukuba isantya sejinjini sehla xa i-brake igxininiswa, i-amplifier ye-vacuum okanye i-components component yayo yimbangela. Ngokuqhelekileyo, le ngxaki iyenzeka ngenxa yezinto eziyilo mveliso kunye nomgaqo wokusebenza kwayo. Le ndlela isetyala elivaliweyo. Itholakala phantsi kwebhodi, kufuphi ne-pedake pedal. I-master cylinder ixhunyiwe kumzimba. Umsebenzi oyintloko wale nqununu kukunciphisa uxinzelelo kwi-pedal xa isantya sinciphisa. Kwintliziyo ye-amplifier yi-diaphragm.

Isifayili

Le nxalenye iyanqineka kwaye iyomelele ngexesha elifanayo. Yenziwe ngezixhobo zepolymer zamanje kwi-polyurethane. Eyona nxalenye ephambili yesalathisi kukho intonga yensimbi ngendlela yesangqa, apho ezimbini zihamba kumacala athile. Enye yezi zinto ixhunyiwe kwi-pedal. Owesibini unesilinda esiyintloko . Ingqungquthela ihlukanisa umzimba kwiindawo ezimbini. Elinye lala malungu lucwecwe. Itholakala kwicala le-cylinder master. Okwesibini ngumlinganiselo wesibhakabhaka kwaye ngenye icala. I-booster breaker boster is seal. Umzimba wayo unomfutho ngaphakathi kwe-zavaltsovan. Amacandelo amabini axhunyelelana ngetyevishini yokusebenza. I-pedake pedal isetyenziswe njenge-drive yale valve.

Umgaqo wokusebenza

Umsebenzi oyintloko wesikhulisi-mveliso kukugcina igumbi kumagumbi amabili okuthetha ngexesha apho i-valve ivulekile kwaye ungacinezeli ukuhlamba. Ukuba ucinezela i-pedal, iqhosha livale. Kule meko, kwicandelo elinoxanduva lokucima, kuya kuba neqabunga elinamandla. Ukuze ufumane olu qhekeza, ukungena kwipayipi ekhokelela ekutheni i-unit unit yondla iyancipha. Kwakhona kwiplani yesimiselo yintwasahlobo yokubuya. Ibuyisela isikhalazo kwisimo sayo esivamile. Xa umqhubi wokuqala ephosa i-pedal, ivalve ivala. Ukuba uqhubeka ucinezela, umgodi omoya uza kubonakala kwigumbi lomoya kwaye umoya uya kungena khona. Uxinzelelo ngaphakathi ekamelweni ngu-760 mm Hg. Ubugcisa. Ngenxa yokungaqhathaniswa, ukucinezelwa kwintonga yomgcini we-cylinder kuya kwanda, kwaye ngoko ke ukunyuka kwe-braking kuyenyuka. Lo mgaqo we-amplifier usebenza kuphela kwiinjini ze-petroli. Kwi-diesel akunakwenzeka ukufumana uncedo ngale ndlela. Ngako oko, i-automakers ixhobisa i-amplifiers kwiiyunithi ze-diesel ngeepompu ezikhethekileyo.

I-Crankshaft kunye nempembelelo yengqiqo yamandla

Njengoko sele kuphawuliwe ngasentla, i-amplifier ye-vacuum inxulumene ngqo kunye neentlobo ezininzi zokutya. Ngoko ke, nakuphi na ukuphulwa komgangatho wendawo yamanzi kuya kuthintela umgangatho womxube womoya-mafutha ongena kwiijinjini zenjini. Umxube womoya kunye nophethiloli, apho kungekho oksijini okwaneleyo, ayiyi kutshisa ngokupheleleyo. Ngako oko, inyunithi yamandla ilahlekelwa ngamandla kunye nokusebenza kakuhle. Yingakho xa ucinezela i-pedal pedal, i-rpm iyawa.

Iindlela zokuxilonga

Ukuba ufumana iingxaki ezifanayo ngelixa usebenzisa isithuthi sakho, kufuneka ufumane ngokukhawuleza ukuba zeziphi iingxaki. Inyaniso kukuba imeko xa ushicilela i-brake, i-rpm iyawa, ayibi kakhulu. Ukuba ekuqaleni kuphela ukuwa kwekhawuleza, emva kwexesha injini nje izitampu ezinomgca wokukhanya we-pedake pedal. Oku kuya kwenzeka ngexesha elibi kakhulu. Masiqaphele, yintoni na kwimoto enokusebenza ngokukhawuleza iyajika ixinzeleleke kwi-brake, kodwa oku kuweleka. Oku kwenzeka ngenxa yoyilo lwe-amplifier.

Hose

Xa ukuhla kwejubane kubaluleke kakhulu, ngoko kuyimfuneko ukuhlola i-hose idibanisa i-amplifier kunye ne-intakeli ezininzi kwiinjini. Ukuba ityhubhu inomonakalo obonakalayo, kwaye le nto ingaba iintlobo ezahlukeneyo okanye iinyembezi, ngoko ingqibelelo yamanzi ayinamandla. Yintoni ekupheleni? Inkqubo yokulungiswa ngokuqhelekileyo kumxube wepetro iyashintsha, yintoni eyenza ukuba umsebenzi ozinzileyo wenjini uphazamiseke. Yingakho xa ucinezela i-pedal pedal, isivinini siwa kunye nezitishi zeenjini. Ukuba kukho umonakalo kwi-hose, kucetyiswa ukuba uyifake esikhundleni. Emva koko ingxaki iza kulungiswa. Ukuba ityhubhu iyafaneleka, kufuneka ukhangele i- air in suction in the various and in the vacuum amplifier ngokwayo. Ukuba oku akunakunceda ukuyicombulula ingxaki, ke isizathu sifanele sifune kwi-amplifier ngokwayo. Kodwa kufuneka kukhunjulwe ukuba akuyi kukwazi ukulungisa indlela yokucima umbane. Ayilungiswanga, kwaye ngoko umcimbi ungaphendulwa kuphela ngokutshintshwa okupheleleyo.

Iimpazamo ezingavumelekanga zokuphucula izicwangciso

Ngaphambi kokuba uthethe ngeengxaki zeenkqubo, kufuneka kuphawulwe ukuba ukungaphumeleli kwendlela akukhubaza ngokupheleleyo inkqubo. Iibhuleki ziya kusebenza, kodwa ukuqhuba imoto nge-amplifier ephosakeleyo, kuya kufuneka usebenzise umgudu ongakumbi wokunciphisa isivinini. Kule meko, xa i-brake igxininiswa, isantya siwa. Esinye seziqhekeza ezidume kakhulu kukuphuka kwepayipi. Ukusuka ngaphantsi kwebhodi, uya kuva umbala wakhe. Yintoni enokuyenza kule meko, sele ikhankanywe ngasentla. Kwakhona, ukuphazamiseka ngaphakathi kwindlela yokukhulisa i-amplifier kunokwenzeka. Ivalve ingonakaliswe. Ngethuba lokusebenza, lukhuni, kwaye ngenxa yokugqoka kwerubha, isithintelo kunye nokwahlula kwe-elasticity.

Ukuxilongwa kwe-vacuum amplifier

Ngoko ke, ukuba uqaphela ukuhla kwejubane xa ucinezela ukuwaphula, ngokokuqala into ukujonga umphambili wokuncedisa. Ngokuqinisekileyo, unako ukuya kwingcali kwi-carburettors. Kodwa ingxaki yokuwa kwemali ingenakunokwenzeka ukuyicombulula. Ukuba kukho uxinzelelo, oku kuya kubangela ukuba umoya ungene kwiintlobo ezininzi. Ngenxa yoko, ukuguquka kuyawa xa i-brake igxininiswa. Umxube we-fuel-air ucoceke kakhulu. Kukho enye indlela yokufumanisa. I-pedake pedal igxinwa ukuya kwii-six times kwi-injini ye-muffled. Emva koko i-pedal igxininiswe kwindawo ephakathi kwaye imoto ivuliwe. Xa i-pedal iwela kwinkqubo yokuqalisa, i-amplifier ilungile. Ukuba uhlala kwindawo efanayo, kufuneka uhlawule ngokukhethekileyo kwinto. Kuhlolisiso olubonakalayo kuyimfuneko ukukhangela amatyala kwiimeko kunye nesizathu se-streaks.

Ukutshintshwa kwe-amplifier ye-vacuum

Ukutshintshwa kwale ndlela kulula ngokwaneleyo nezixhobo eziyimfuneko. Kwiimoto ezahlukahlukeneyo, kunokuba kuyimfuneko ukuphazamisa amatanki okwandisa. Ngethuba lo msebenzi, susa i-cylinder ye-freake, kwaye ke i-amplifier ngokwayo. Ngokwexesha lithatha malunga neeyure ezintathu.

Isishwankathelo

I-amplifier ye-vacuum yinto ebalulekileyo yokwenza nayiphi na imoto. Uyenza inkqubo yokuqhekeka lula kwaye ikhululeke. Yingakho xa ucinezela i-brake, iinguqulelo ziwa. Isizathu si-amplifier okanye i-system failure.
