Pompo ya breki.
Pompu ya mabuleki ndi gawo lofunika kwambiri la mabuleki a chassis, ntchito yake yayikulu ndikukankhira brake pad, brake pad friction brake drum. Chepetsani liwiro ndikuyimitsa. Pambuyo poti brake yakanikiza, pampu yayikulu imapanga thrust kuti ikanikizire mafuta a hydraulic ku sub-pump, ndipo pisitoni mkati mwa sub-pump imayamba kuyenda pansi pa mphamvu yamadzimadzi kuti ikankhire brake pad.
Mabuleki a hydraulic amapangidwa ndi brake master pump ndi thanki yosungiramo mafuta a brake. Amalumikizidwa ku brake pedal kumapeto kwina ndi brake chubu kumbali inayo. Mafuta a brake amasungidwa mu brake master pump, ndipo pali malo otulutsira mafuta ndi malo olowera mafuta.
konza
Mabuleki agalimoto amagawidwa m'magulu awiri: mabuleki a mpweya ndi mabuleki a hydraulic. Pumpu yapansi ya mabuleki a mpweya imayikidwa pampu yaing'ono.
1. Buleki ya mpweya imapangidwa ndi compressor ya mpweya (yomwe imadziwika kuti pampu ya mpweya), masilinda osachepera awiri osungira mpweya, pampu ya brake master, valavu yotulutsa mwachangu ya gudumu lakutsogolo, ndi valavu yotumizira ya gudumu lakumbuyo. Buleki ili ndi mapampu anayi, ma dispensing backs anayi, makamera anayi, nsapato zisanu ndi zitatu za mabuleki ndi ma hub anayi a mabuleki. Buleki ya hydraulic
2. Bulaki yamafuta imapangidwa ndi pumpu ya brake master (hydraulic brake pump) ndi thanki yosungiramo mafuta a brake. Magalimoto akuluakulu amagwiritsa ntchito mabuleki ampweya, ndipo magalimoto wamba ndi mabuleki amafuta, kotero pumpu yonse ya brake ndi pumpu ya brake ndi ma hydraulic brake pump. Pumpu ya brake (hydraulic brake pump) ndi gawo lofunika kwambiri la dongosolo la brake. Mukaponda mbale ya brake, pumpu ya brake master idzatumiza mafuta a brake kudzera mu payipi kupita ku pumpu ya brake. Pumpu ya brake subpump ili ndi ndodo yolumikizira yomwe imayang'anira nsapato ya brake kapena khungu la brake. Mukayimitsa, mafuta a brake omwe ali mu chubu cha brake amakankhira ndodo yolumikizira pa pumpu ya brake, kotero kuti nsapato ya brake imamatira flange disc pa gudumu kuti iyimitse gudumu. Zofunikira zaukadaulo za pumpu ya brake yagalimoto ndizokwera kwambiri, chifukwa zimakhudza mwachindunji miyoyo ya anthu. Galimoto ikayimitsa, chotulutsira mafuta chimatseguka ndipo cholowera mafuta chimatsekedwa. Pansi pa kukakamizidwa kwa pistoni ya thupi la pampu, chitoliro cha mafuta a brake chimatulutsidwa kuchokera ku chitoliro cha mafuta kupita ku pampu iliyonse ya brake kuti chigwire ntchito ya brake. Pamene mbale ya brake yatulutsidwa. Malo otulutsira mafuta mu pampu ya brake master adzatsekedwa, ndipo cholowera mafuta chidzatsegulidwa, kotero kuti mafuta a brake kuchokera pampu iliyonse ya nthambi ya brake kubwerera ku pampu ya brake master, kubwerera ku momwe analili poyamba. Galimoto imayendetsedwa ndi pampu ya mpweya kudzera mu injini, ndipo mpweya umakanikizidwa ku mpweya wopanikizika kwambiri womwe umasungidwa mu reservoir. Limodzi mwa malo osungira mafuta likhoza kulumikizidwa ku pampu ya brake master kudzera mu paipi. Pampu yayikulu ya brake imagawidwa m'zipinda ziwiri, chipinda chapamwamba chimayang'anira gudumu lakumbuyo, ndipo chipinda chapansi chimayang'anira gudumu lakutsogolo. Dalaivala akakanikiza pedal ya brake, mpweya wapamwamba umatsegulidwa koyamba, ndipo mpweya wopanikizika kwambiri wa reservoir ya mpweya umatumizidwa ku valavu yolumikizira, ndikutulutsa pistoni yowongolera ya valavu yolumikizira. Panthawiyi, mpweya wa reservoir ina ukhoza kulumikizidwa kudzera mu valavu yolumikizira ndi ma sub-pump awiri a brake yakumbuyo. Ndodo yokakamiza ya pampu ya brake imakankhidwira patsogolo, ndipo CAM imazunguliridwa pa ngodya posintha kumbuyo. CAM ndi yachilendo, ndipo nthawi yomweyo, nsapato ya brake imatambasulidwa ndipo ng'oma ya brake imapanga kukangana kwa brake. Pamene chipinda chapamwamba cha pampu ya brake master chatsegulidwa, chipinda chapansi chimatsegulidwanso, ndipo mpweya wothamanga kwambiri umalowa mu valavu yotulutsa mwachangu, kenako umagawidwa ku pampu ya brake ya mawilo awiri akutsogolo. Momwemonso ndi mawilo akumbuyo. Dalaivala akamasula pedal ya brake, zipinda zam'mwamba ndi zakumunsi za mpweya zimatsekedwa, ndipo pisitoni ya valavu yolowera mwachangu ya gudumu lakutsogolo ndi valavu yolumikizira ya gudumu lakumbuyo zimabwerera pansi pa mphamvu ya kasupe. Pumpu ya brake yakutsogolo ndi yakumbuyo imalumikizidwa ndi mlengalenga wa chipinda cha mpweya, ndipo ndodo yopukusira imabwerera pamalo ake ndipo brake imatha. Kawirikawiri, gudumu lakumbuyo limayamba kusweka, ndipo gudumu lakutsogolo limasweka pambuyo pake, zomwe zimathandiza dalaivala kuwongolera komwe akupita.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
