The pneumatic actuator ya brake system ndi yosavuta komanso yogwira ntchito bwino, komabe, kutalika kwa mizere kungayambitse kuchedwa kwa kayendedwe ka ma brake a ma axles akumbuyo.Vutoli limathetsedwa ndi gawo lapadera - valavu ya accelerator, chipangizo ndi ntchito yomwe yaperekedwa m'nkhaniyi.
Kodi valve yothamanga ndi chiyani?
The accelerator valve (MC) ndi gawo lowongolera la brake system yokhala ndi pneumatic drive.Msonkhano wa valve womwe umagawira mpweya woponderezedwa umayenda pakati pa zinthu za pneumatic system molingana ndi njira zogwiritsira ntchito mabuleki.
Criminal Code ili ndi ntchito ziwiri:
• Kuchepetsa nthawi yoyankha kwa ma wheel wheel ma axles akumbuyo;
• Kupititsa patsogolo luso la kuyimika magalimoto ndi makina osungira mabuleki.
Magawowa amakhala ndi magalimoto ndi mabasi, nthawi zambiri gawoli limagwiritsidwa ntchito pamakalavani ndi ma semitrailer.
Mitundu ya ma valve a accelerator
Kampani yoyang'anira ikhoza kugawidwa m'magulu malinga ndi momwe angagwiritsire ntchito, njira yoyendetsera ndi kasinthidwe.
Malinga ndi kugwiritsidwa ntchito kwa Criminal Code, pali mitundu iwiri:
- Kuwongolera ma contours a magalimoto (pamanja) ndi mabuleki opuma;
- Kuwongolera zinthu za pneumatic actuator ya actuators ya main brake system ya ma axles akumbuyo.
Nthawi zambiri, ma accelerator ma valve amaphatikizidwa mumayendedwe oimikapo magalimoto ndi ma brake, ma actuators omwe ndi ma accumulators amphamvu (EA) ophatikizidwa ndi zipinda zopumira.Chigawochi chimayang'anira dera la EA pneumatic, kutulutsa magazi mwachangu panthawi ya braking komanso kutulutsa kwake mwachangu kuchokera ku silinda ya mpweya yosiyana ikachotsedwa pamabuleki.
Ma valve a Accelerator amagwiritsidwa ntchito mobwerezabwereza kuwongolera mabuleki akuluakulu.Pamenepa, chipangizochi chimatulutsa mpweya wothamanga kuchokera ku silinda yosiyana ya mpweya kupita ku zipinda za braking panthawi ya braking ndi kutuluka magazi.
Malinga ndi njira yoyendetsera, Criminal Code imagawidwa m'magulu awiri akuluakulu:
• Kulamulidwa ndi pneumatic;
• Kuyendetsedwa ndi makompyuta.
Accelerator yoyendetsedwa ndi magetsi
Ma valve oyendetsedwa ndi pneumatic ndi osavuta komanso ogwiritsidwa ntchito kwambiri.Amayang'aniridwa ndi kusintha kupanikizika kwa mpweya wochokera ku ma valve akuluakulu kapena a manual brake.Ma valve oyendetsedwa ndi magetsi amakhala ndi ma valve a solenoid, omwe ntchito yake imayendetsedwa ndi chipangizo chamagetsi.Makampani oyang'anira oterowo amagwiritsidwa ntchito pamagalimoto okhala ndi machitidwe osiyanasiyana odzitetezera (EBS ndi ena).
Malinga ndi kasinthidwe, Criminal Code imagawidwanso m'magulu awiri:
• Popanda zigawo zowonjezera;
• Ndi kuthekera khazikitsa muffler.
Mu kampani yoyang'anira ya mtundu wachiwiri, phiri limaperekedwa kuti akhazikitse muffler - chipangizo chapadera chomwe chimachepetsa mphamvu ya phokoso la mpweya wotuluka magazi.Komabe, machitidwe a mitundu yonse ya ma valve ndi ofanana.
Kupanga ndi mfundo yogwiritsira ntchito ma valve accelerator
Chosavuta kwambiri ndi kapangidwe ndi magwiridwe antchito amakampani oyang'anira ma brake system.Zimakhazikitsidwa pazitsulo zachitsulo zomwe zimakhala ndi mapaipi atatu, mkati mwake muli pisitoni ndi mavavu otulutsa ndi odutsa.Tiyeni tione mwatsatanetsatane kamangidwe ndi ntchito ya mtundu uwu wa kasamalidwe kasamalidwe chitsanzo chitsanzo cha chilengedwe chonse 16.3518010.
Chipangizocho chimalumikizidwa motere: pini I - ku mzere wowongolera wa dongosolo la pneumatic (kuchokera ku valavu yayikulu ya brake), pini II - kwa wolandila, pini III - ku mzere wa brake (ku zipinda).Valve imagwira ntchito mosavuta.Pakuyenda kwa galimotoyo, kupanikizika kochepa kumawonekera pamzere wolamulira, kotero pisitoni 1 imakwezedwa, valavu yotulutsa 2 imatsegulidwa ndipo mzere wonyezimira kupyolera mu terminal III ndi njira 7 imagwirizanitsidwa ndi mlengalenga, mabuleki amaletsedwa. .Pamene braking, kuthamanga kwa mzere wolamulira ndi chipinda "A" kumawonjezeka, pisitoni 1 imasunthira pansi, valavu 2 imakhudzana ndi mpando 3 ndikukankhira valavu yodutsa 4, yomwe imapangitsa kuti ichoke pampando. 5. Chotsatira chake, pin II imagwirizanitsidwa ndi chipinda cha "B" ndi pini III - mpweya wochokera ku wolandira umapita ku zipinda zowonongeka, galimotoyo imaphwanyidwa.Poletsa kuletsa, kupanikizika kwa mzere wowongolera kumatsika ndipo zomwe zafotokozedwa pamwambapa zimawonedwa - chingwe cha brake chimalumikizidwa ndi njira 7 kudzera pa pini III ndipo mpweya wochokera m'zipinda za brake umatulutsidwa mumlengalenga, galimotoyo imatsekedwa.
Chipangizo cha valve ya KAMAZ accelerator
Pampu yamanja yamtundu wa bellows imagwira ntchito mosavuta.Kuponderezana kwa thupi ndi dzanja kumabweretsa kuwonjezeka kwa kupanikizika - chifukwa cha kukakamizidwa uku, valve yotulutsa mpweya imatsegulidwa (ndipo valve yolowera imakhalabe yotsekedwa), mpweya kapena mafuta mkati mwake amakankhidwira mzere.Kenaka thupi, chifukwa cha kusungunuka kwake, limabwerera ku mawonekedwe ake oyambirira (kuwonjezeka), kupanikizika mkati mwake kumatsika ndikukhala otsika kuposa mlengalenga, valavu yotulutsa mpweya imatseka, ndipo valavu yolowetsa imatsegulidwa.Mafuta amalowa mu mpope kudzera mu valve yotsegula yotsegula, ndipo nthawi yotsatira thupi likakanikizidwa, kuzungulira kumabwereza.
Kampani yoyang'anira, yopangidwira "handbrake" ndi brake yopuma, imakonzedwa mofanana, koma sichiyendetsedwa ndi valavu yaikulu ya brake, koma ndi valavu yowonongeka ("handbrake").Tiyeni tione mfundo ya ntchito ya unit chitsanzo cha lolingana galimoto KAMAZ.Terminal I yake imalumikizidwa ndi mzere wa EA wa mabuleki akumbuyo, terminal II imalumikizidwa ndi mlengalenga, terminal III imalumikizidwa ndi wolandila, terminal IV imalumikizidwa ndi mzere wa valve brake hand.Pamene galimoto ikuyenda, mpweya wothamanga kwambiri umaperekedwa ku pini III ndi IV (kuchokera ku cholandira chimodzi, kotero kupanikizika kuli kofanana pano), koma malo omwe ali pamwamba pa pistoni 3 ndi aakulu kuposa apansi, kotero ili m’malo apansi.Valavu yotulutsa 1 imatsekedwa, ndipo valavu yolowera 4 imatsegulidwa, ma terminal I ndi III amalumikizidwa kudzera muchipinda "A", ndipo chotuluka mumlengalenga II chatsekedwa - mpweya woponderezedwa umaperekedwa kwa EA, akasupe awo amapanikizidwa ndipo dongosolo ndi disinhibited.
Galimoto ikayikidwa pa brake yoyimitsira kapena ikatsegulidwa, kupanikizika kwa IV terminal kumachepa (mpweya umatuluka ndi valavu yamanja), pisitoni 3 imatuluka, valavu yotulutsa mpweya imatsegulidwa, ndikulowetsa. valavu, m'malo mwake, imatseka.Izi zimatsogolera ku kulumikizana kwa ma terminals I ndi II ndikulekanitsa ma terminal I ndi III - mpweya wochokera ku EA umalowetsedwa mumlengalenga, akasupe omwe ali mkati mwake amachotsedwa ndipo amatsogolera ku braking yagalimoto.Mukachotsedwa pa handbrake, njirazo zimapita motsatira ndondomeko.
Makampani oyang'anira pakompyuta amatha kugwira ntchito monga momwe tafotokozera pamwambapa, kapena kuyendetsedwa ndi gawo lamagetsi molingana ndi ma algorithms omwe adayikidwa.Koma kawirikawiri, amathetsa mavuto omwewo monga ma valve oyendetsedwa ndi pneumatic.
Monga mukuonera, valavu yothamangitsira imagwira ntchito za relay - imayendetsa zigawo za pneumatic system kutali ndi valavu yaikulu ya brake kapena valavu yamanja, kuteteza kutaya kwa kuthamanga kwa mizere yaitali.Izi ndi zomwe zimatsimikizira ntchito yachangu komanso yodalirika ya mabuleki pazitsulo zam'mbuyo zagalimoto.
Nkhani zakusankha ndi kukonza ma valve accelerator
Panthawi yoyendetsa galimoto, kampani yoyang'anira, monga zigawo zina za dongosolo la pneumatic, imagonjetsedwa ndi katundu wambiri, choncho iyenera kuyang'aniridwa nthawi ndi nthawi kuti iwononge kuwonongeka, kutulutsa mpweya, ndi zina zotero.
Mukasintha, ndikofunikira kukhazikitsa mayunitsi amtunduwu ndi zitsanzo zomwe zimalimbikitsidwa ndi automaker.Ngati chisankho chapangidwa kukhazikitsa ma analogue a valve yoyambirira, ndiye kuti gawo latsopanolo liyenera kufanana ndi mawonekedwe apachiyambi ndi kukula kwake.Ndi zikhalidwe zina, valavu silingagwire ntchito moyenera komanso osatsimikizira kugwira bwino ntchito kwa ma brake system.
Ndi kusankha koyenera kwa valve accelerator ndi kukonza panthawi yake, dongosolo la brake la galimoto kapena basi lidzagwira ntchito modalirika, kupereka chitonthozo ndi chitetezo chofunikira.
