Master ananyema yamphamvu - chipangizo ndi mfundo ntchito

Ntchito yoyamba ya hydraulic drive ya mabuleki agalimoto ndikusintha mphamvu yakukankhira pedal kukhala kuthamanga kwamadzimadzi molingana ndi mizere. Izi zimachitidwa ndi silinda yayikulu ya brake (GTZ), yomwe ili m'dera la chishango chamoto ndikulumikizidwa ndi ndodo ku pedal.

Kodi GTC iyenera kuchita chiyani?

Mabuleki amadzimadzi ndi osasunthika, kotero kuti kusamutsa kukakamiza kudzera mu ma pistoni a ma silinda oyendetsa, ndikokwanira kugwiritsa ntchito pisitoni ya aliyense wa iwo. Yomwe idapangidwira izi ndipo imalumikizidwa ndi brake pedal imatchedwa chachikulu.

GTZ yoyamba idakonzedwa kuti ikhale yosasinthika. Ndodo idalumikizidwa ndi pedal, kumapeto kwachiwiri komwe adakanikizira pisitoni yokhala ndi khafu yosindikizira. Danga kuseri kwa pisitoni ndi lodzaza ndi madzimadzi otuluka mu silinda kudzera mu mgwirizano wa chitoliro. Kuchokera pamwamba, madzi amadzimadzi omwe amakhala mu thanki yosungirako anaperekedwa. Umu ndi momwe ma clutch master cylinders amapangidwira tsopano.

Koma dongosolo la brake ndilofunika kwambiri kuposa kuwongolera ma clutch, kotero ntchito zake ziyenera kubwerezedwa. Iwo sanali kulumikiza masilindala awiri kwa wina ndi mzake, njira yololera anali kulenga GTZ mtundu tandem, kumene pistoni awiri zili mndandanda mu yamphamvu imodzi. Aliyense wa iwo amagwira ntchito pa dera lake, kutayikira kwa wina pafupifupi alibe mphamvu pa ntchito ya mzake. Ma contours amagawidwa pamakina a gudumu m'njira zosiyanasiyana, nthawi zambiri amagwiritsidwa ntchito mfundo ya diagonal, code, ngati kulephera kumodzi, mabuleki akumbuyo ndi gudumu lakutsogolo amakhalabe akugwira ntchito, koma osati mbali imodzi, koma pambali. diagonal wa thupi, kumanzere kutsogolo ndi kumbuyo kumanja kapena mosemphanitsa. Ngakhale pali magalimoto omwe ma hoses a mabwalo onsewa amakwanira mawilo akutsogolo, akugwira ntchito pa silinda yawoyawo.

Zithunzi za GTZ

Silinda imamangiriridwa ku chishango cha injini, koma osati mwachindunji, koma kudzera mu chowonjezera chotsitsimula chomwe chimapangitsa kuti kusavuta kukanikiza chopondapo. Mulimonsemo, ndodo ya GTZ ikugwirizana ndi pedal, kulephera kwa vacuum sikungabweretse kulephera kwa mabuleki.

GTC ikuphatikizapo:

• thupi la silinda, mkati mwake momwe ma pistoni amasuntha;
• yomwe ili pamwamba pa thanki yokhala ndi brake fluid, yokhala ndi zopangira zosiyana pamagulu aliwonse;
• ma pistoni awiri otsatizana okhala ndi akasupe obwerera;
• zisindikizo zamtundu wa milomo pa pistoni iliyonse, komanso polowera ndodo;
• pulagi ya ulusi yomwe imatseka silinda kuchokera kumapeto moyang'anizana ndi ndodo;
• zitsulo zopangira magetsi pazigawo zilizonse;
• flange yokwezera ku thupi la vacuum booster.

Malo osungiramo madziwa amapangidwa ndi pulasitiki yowonekera, chifukwa ndikofunika kulamulira nthawi zonse pamlingo wa brake fluid. Kunyamula mpweya ndi pistoni sikuvomerezeka, mabuleki adzalephera kwathunthu. Pamagalimoto ena, akasinja amayikidwa pamalo omwe dalaivala amawoneka mosalekeza. Kwa olamulira akutali, akasinja ali ndi sensor yamlingo ndikuwonetsa kugwa kwake pagawo la zida.

GTZ ntchito

Poyamba, ma pistoni ali kumbuyo, mazenera kumbuyo kwawo amalumikizana ndi madzi mu thanki. Akasupe amawalepheretsa kuyenda modzidzimutsa.

Chifukwa cha khama lochokera ku ndodo, pisitoni yoyamba imayendetsa ndikuletsa kulankhulana ndi thanki ndi m'mphepete mwake. Kuthamanga kwa silinda kumawonjezeka, ndipo pisitoni yachiwiri imayamba kusuntha, ikukoka madzi m'mphepete mwake. Mipata imasankhidwa mu dongosolo lonse, ma cylinders ogwira ntchito amayamba kukakamiza pamatope. Popeza palibe kusuntha kwa magawo, ndipo madzimadziwo ndi osasunthika, kuyenda kwina kwa pedal kumayima, dalaivala amangoyendetsa kupanikizika mwa kusintha mphamvu ya phazi. Kuchuluka kwa braking kumadalira izi. Danga lakumbuyo kwa pistoni limadzazidwa ndi madzi kudzera m'mabowo obwezera.

Mphamvu ikachotsedwa, ma pistoni amabwerera pansi pa chikoka cha akasupe, madziwo amayendanso m'mabowo otsegulira motsatana.

Mfundo yosungira

Ngati mabwalo amodzi ataya kulimba kwake, ndiye kuti madzi omwe ali kumbuyo kwa pisitoni yofananira adzafinyidwa kwathunthu. Koma kuthamangitsidwanso mwamsanga kudzapereka madzi ochulukirapo ku dera labwino, kuonjezera kuyenda kwa pedal, koma kuthamanga kwa dera labwino kudzabwezeretsedwa ndipo galimotoyo idzatha kutsika. Sikoyenera kubwereza kukanikiza, kutaya zambiri zatsopano kuchokera ku tanki yoponderezedwa kudzera mu dera lotayirira. Pambuyo poyimitsa, zimangotsala pang'ono kupeza zovuta ndikuzichotsa popopera dongosolo kuchokera ku mpweya wotsekedwa.

Zotheka kuthekera

Mavuto onse a GTZ amalumikizidwa ndi kulephera kwa chisindikizo. Kutayikira kudzera pa ma piston cuffs kumatsogolera ku bypass yamadzimadzi, pedal idzalephera. Kukonza mwakusintha zida sikuthandiza, tsopano ndi chizolowezi kusintha msonkhano wa GTZ. Panthawiyi, kuvala ndi kuwonongeka kwa makoma a silinda kunayamba kale, kubwezeretsedwa kwawo sikuli koyenera mwachuma.

Kutulutsa kumatha kuwonekeranso pamalo pomwe tanki imamangiriridwa, apa kusintha zisindikizo kungathandize. Tanki yokhayo imakhala yolimba mokwanira, kuphwanya kulimba kwake sikuchitika kawirikawiri.

Kuchotsa koyamba kwa mpweya kuchokera ku silinda yatsopano kumachitika podzaza ndi madzi ndi mphamvu yokoka ndi zomangira za mabwalo onsewa atamasulidwa. Kupopera kwina kwina kumachitika kudzera muzoyika za masilinda ogwirira ntchito.
