Musanayambe galimoto, mudzamva kuti chopondapo cha brake ndi "chovuta", ndiko kuti, pamafunika mphamvu zambiri kukankhira pansi. Izi makamaka zimaphatikizapo gawo lofunika kwambiri la brake system - brake booster, yomwe imatha kugwira ntchito pamene injini ikuyenda.
Chiwongolero chomwe chimagwiritsidwa ntchito kwambiri ndi brake booster ndi vacuum booster, ndipo malo opumulira mu chilimbikitso amatha kupangidwa pokhapokha injini ikugwira ntchito. Panthawiyi, chifukwa mbali ina ya chilimbikitso ndi kuthamanga kwa mlengalenga, kusiyana kwapakati kumapangidwa, ndipo tidzamva kukhala omasuka tikamagwiritsa ntchito mphamvu. Komabe, injiniyo ikangozimitsidwa ndipo injiniyo itasiya kugwira ntchito, vacuumyo imazimiririka pang’onopang’ono. Chifukwa chake, ngakhale chopondapo chikhoza kukanikizidwa mosavuta kuti chipangitse braking injini ikangozimitsidwa, ngati muyesa kangapo, malo opumira apita, ndipo palibe kusiyana kokakamiza, chopondapo chimakhala chovuta kukanikiza.
Ma brake pedal mwadzidzidzi amauma
Pambuyo pomvetsetsa mfundo yogwirira ntchito ya brake booster, titha kumvetsetsa kuti ngati chopondapo chikuwuma mwadzidzidzi pamene galimoto ikuyenda (kukana kumawonjezeka popondapo), ndiye kuti chiwongolero cha brake ndi chotheka. Pali zovuta zitatu zomwe zimachitika kawirikawiri:
(1) Ngati valavu ya cheke mu thanki yosungiramo vacuum mu dongosolo la mphamvu ya brake yawonongeka, idzakhudza kubadwa kwa malo otsekemera, kupanga digiri ya vacuum yosakwanira, kusiyana kwapakati kumakhala kochepa, motero kumakhudza ntchito ya mphamvu ya brake. dongosolo, kupangitsa kukana kuwonjezeka (osati mwachibadwa). Panthawiyi, zigawo zofananira ziyenera kusinthidwa panthawi yake kuti zibwezeretse ntchito ya dera la vacuum.
(2) Ngati pali mng'alu wa payipi pakati pa thanki yakupumulira ndi brake master mpope booster, zotsatira zake zimakhala zofanana ndi zomwe zidachitika m'mbuyomu, digiri ya vacuum mu tanki yakunyumba siikwanira, zomwe zimakhudza magwiridwe antchito a brake booster system, ndipo kusiyana kwamphamvu komwe kumapangidwa kumakhala kochepa kuposa kwanthawi zonse, kumapangitsa kuti brake ikhale yovuta. Bwezerani chitoliro chowonongeka.
(3) Ngati mpope chilimbikitso palokha ali ndi vuto, sangathe kupanga vacuum m'dera, chifukwa ananyema pedal ndi kovuta kusiya. Ngati mumva phokoso la "hiss" pamene mukusindikiza pedal ya brake, ndizotheka kuti pali vuto ndi mpope wowonjezera womwewo, ndipo mpope wowonjezera uyenera kusinthidwa mwamsanga.
Vuto la ma brake system limagwirizana mwachindunji ndi chitetezo chagalimoto ndipo silingatengeke mopepuka. Ngati mukuwona kuti brake imawuma mwadzidzidzi pakuyendetsa, muyenera kukhala tcheru komanso chidwi chokwanira, pitani kumalo okonzera nthawi kuti mukawonere, m'malo mwa mbali zolakwika, ndikuwonetsetsa kuti ma brake system akugwiritsa ntchito bwino.
