Umgaqo we-vacuum booster.
I-vacuum booster isebenzisa i-vacuum (uxinzelelo olubi) ukunyusa amandla aqhutywe ngumqhubi kwi-pedal, ngaloo ndlela yandisa amandla okunyathela. Umgaqo-nkqubo othile wokusebenza ngolu hlobo lulandelayo:
Xa i-injini isebenza, impompo ye-booster ye-brake yenza i-vacuum kwelinye icala le-booster ngokufunxa emoyeni, okwenza umahluko woxinzelelo kunye noxinzelelo lomoya oluqhelekileyo kwelinye icala. Lo mahluko woxinzelelo uvumela i-diaphragm ukuba ihambe iye ekupheleni koxinzelelo oluphantsi, ngaloo ndlela ityhala intonga yokutyhala yepompo ye-brake master.
Ukusebenza, intonga yokutyhala ngokutsha ibamba i-pedal yebrake kwindawo yayo yokuqala. Ngeli xesha, i-valve yokutshekisha kwindawo yokudibanisa kwi-tube ye-vacuum kunye ne-vacuum booster ivuliwe. I-diaphragm ngaphakathi kwe-booster iyahlula ibe yindlu yomoya yokwenyani kunye negumbi lomoya lesicelo, eliqhele ukuba lodwa kwihlabathi langaphandle kodwa linokudityaniswa nomoya ngezixhobo ezibini zevalvu.
Xa umqhubi ecinezela i-pedal ye-brake, intonga yokutyhala ivala ivalve yevacuum, ngelixa ivalve yomoya kwelinye icala ivula, ivumela umoya ukuba ungene. Ngaphantsi kwesenzo soxinzelelo olubi, i-diaphragm itsalwa kwicala elinye lepompo ye-brake master, eqhuba intonga yokutyhala kwaye ikhulise ngakumbi amandla omlenze.
Olu yilo luvumela umqhubi ukuba alawule ukuhla kwesithuthi ngokulula ngakumbi xa i-pedal ye-brake icinezelekile, ukuphucula ukhuseleko lokuqhuba.
Ngaba i-vacuum booster kulula ukuyiqhawula?
I-vacuum booster ayilula ukuyonakalisa, nje ukuba ifakwe ngokufanelekileyo kwaye isetyenziswe, inokusebenza ngokuqhelekileyo ixesha elide. Nangona kunjalo, imeko yokusebenza yempompo ye-vacuum booster inokuchaphazeleka kwizinto ezininzi, kubandakanywa iimeko zokusetyenziswa kwesithuthi, iimeko zokusingqongileyo, kunye nokuba ukugcinwa rhoqo kunye nokugcinwa kuqhutywe.
Ukusetyenziswa kunye nokugcinwa ngokufanelekileyo: Ngethuba nje isithuthi sihlala sihlala kwiimeko ezinzima zokuqhuba (ezifana nokushisa okuphezulu, umswakama ophezulu okanye impembelelo ephezulu), okanye isithuthi asigcinwanga rhoqo, iimpompo ze-booster zinokuba neengxaki. Ke ngoko, ukufakela okuchanekileyo, ukusetyenziswa kunye nokugcinwa rhoqo kuyisitshixo sokugcina i-vacuum booster ikwimeko elungileyo yokusebenza.
Izinto ezisingqongileyo: Amandla e-vacuum booster achaphazeleka kakhulu yimiba yokusingqongileyo, njengokungabikho kwe-vacuum ebangelwa ukuqhuba kwiindawo eziphakamileyo, kunye nokungabikho kwe-vacuum ebangelwa iimeko zokuqala ezibandayo. Le miba yokusingqongileyo kufuneka iqwalaselwe ekuyilweni nasekuphuhlisweni, kwaye ekusetyenzisweni kwemoto yonke imihla, umnini kufuneka abe nesixa esithile sovavanyo lokuzihlola ukujongana nezi ngxaki.
Iimpazamo eziqhelekileyo: Iimpazamo eziqhelekileyo ziquka umonakalo we-vacuum booster check valve, onokuthi ukhokelele kwisitywina esikhululekile, iibhuleki ezinzima, kunye nesantya esingazinzanga sokungenzi nto xa uqhoqhoqho. Ukongeza, ukuvuza kwe-oyile kuyingxaki eqhelekileyo, xa i-brake master impompa ukuvuza kweoyile, ukuya kuthi ga ekupheleni kwetywina le-oyile lingene nzulu kwi-booster, okukhokelela kwi-vacuum booster diaphragm deformation, itywina alingqongqo, ukuhla kwamandla.
Ukuze kugcinwe imeko efanelekileyo yokusebenza kwe-vacuum booster, kucetyiswa ukuba umniniyo ahlole kwaye agcine inkqubo ye-brake ngexesha xa usebenzisa imoto ngamaxesha aqhelekileyo. Ukongeza, ipompo ye-vacuum booster luhlobo lokuchaneka okuphezulu kunye nempompo ebuthathaka, ekufuneka ithotyelwe ngokungqongqo kwimithetho yokuthambisa, jonga ukuba ngaba ukusebenza kunye nokuthambisa kuqhelekile, kwaye ujonge ukuba ipompo inento yokuvuza. Ukuba impompo ye-vacuum booster ayisetyenziswanga ixesha elide, akufuneki isebenze kumthwalo opheleleyo ngoko nangoko xa iphinda isetyenziswa.
Ivacuum booster yaphukile
Ukusebenza kwe-vacuum booster eyaphukileyo ikakhulu ibandakanya ukusebenza kakubi kwe-braking okanye akukho sithintelo sokunyathela, ukucotha okanye ukungabuyi kwe-brake pedal, isandi esicacileyo esingaqhelekanga sinokuviwa emva kokunyathela i-pedal ye-brake, icala le-braking pedal okanye ukungcangcazela, kunye nemvakalelo ye-brake pedal. ethambileyo. Ezi mpawu zibonisa ukuba i-vacuum booster ingaba nephutha, njengokuvuza komoya okanye umonakalo, kwaye kufuneka ihlolwe kwaye ilungiswe kwangethuba ukuze kuqinisekiswe ukhuseleko lokuqhuba.
Ukubaluleka kwe-vacuum booster kukuba inceda umqhubi ukuba aphucule amandla e-brake kwaye anciphise ubuninzi bomsebenzi we-brake yomqhubi, ngaloo ndlela ephucula ukusebenza kakuhle kunye nokhuseleko lwe-brake. Xa i-vacuum booster isilela, njengokuvuza komoya, kunokukhokelela ekwehleni okukhulu kokusebenza kwebraking, okanye ilahleko epheleleyo yesiphumo sokuqhobosha, kwandisa kakhulu umngcipheko wokuqhuba.
Ukusebenza kwevacuum booster ukuvuza komoya kunokubandakanya ukusebenza kakubi kwebrake, ukucotha okanye kungabikho ukubuya kwebrake pedal, kunye nesandi esingaqhelekanga esicacileyo sinokuviwa emva kokuba inyhwebo yebrake icinezelwe. Ukuba ezi zimpawu zifunyenwe, kucetyiswa ukuba uhlolisise kwaye ulungise i-vacuum booster ngexesha.
