Magalimoto angapo amakono ali ndi zogawa - ma gearbox apadera omwe amawirikiza kawiri kuchuluka kwa magiya otumizira.Wogawanitsa amawongoleredwa ndi valavu ya pneumatic - werengani za valavu iyi, kapangidwe kake ndi kagwiritsidwe ntchito kake, komanso za kusankha kolondola, m'malo ndi kukonza valavu m'nkhaniyi.
Kodi valve actuation ya divider ndi chiyani?
The divider actuation valve ndi gawo la pneumomechanical gear shift system ya chogawa chagalimoto;valavu ya pneumatic yomwe imapereka kusintha kwakutali kwa chogawa cha gearbox popereka mpweya kwa wogawa ndi silinda yamphamvu ya pneumatic panthawi yomwe clutch imachotsedwa kwathunthu.
Mu zitsanzo zambiri zamagalimoto apanyumba ndi akunja, gearbox ili ndi chogawa - gawo limodzi la gearbox, lomwe limachulukitsa kuchuluka kwa magiya otumizira.Wogawanitsa amakulitsa kwambiri kuthekera kwa bokosi la gear, ndikuwonjezera kusinthasintha kwa kuyendetsa mumsewu wosiyanasiyana komanso pansi pa katundu wosiyanasiyana.Kuwongolera kwa gawoli pamagalimoto ambiri kumachitika pogwiritsa ntchito makina a pneumomechanical divider gear shift system, amodzi mwa malo ofunikira mu dongosolo lino amakhala ndi valavu yophatikizira yogawa.
The divider actuation valve imagwira ntchito yofunika kwambiri: mothandizidwa, mpweya woponderezedwa kuchokera ku pneumatic cylinder umaperekedwa ku silinda yamphamvu ya pneumatic ya divider gear shift mechanism yomwe imayikidwa pa crankcase ya gearbox.Valavu imalumikizidwa mwachindunji ndi clutch actuator, zomwe zimatsimikizira kuti zida zogawa zimasunthidwa pomwe chopondapo cha clutch chikukhumudwa kwambiri komanso popanda kuwongolera kwina kwa dalaivala.Kugwiritsira ntchito molakwika kwa valve kapena kulephera kwake pang'ono kapena kumasokoneza ntchito ya wogawanitsa, zomwe zimafuna kukonza.Koma musanayambe kukonza kapena kusintha valavu iyi, ndikofunikira kumvetsetsa kapangidwe kake ndi mawonekedwe ake.
Chipangizo ndi mfundo yogwiritsira ntchito mavavu osinthira pazigawo
Ma valve onse ogawa omwe amagwiritsidwa ntchito masiku ano ali ndi mapangidwe ofanana.Maziko a unit ndi mlandu wachitsulo ndi njira yotalika ndi zinthu zomangira unit ku thupi kapena mbali zina za galimoto.Kumbuyo kwa thupi pali valavu yolowera, pakati pawo pali chibowo chokhala ndi tsinde la valve, ndipo kutsogolo thupi limatsekedwa ndi chivindikiro.Ndodoyo imadutsa pachivundikirocho ndikupitirira kupitirira nyumbayo, apa imakutidwa ndi chivundikiro cha rabara (fuse fuse), momwe chitsulo choyendera ndodo chimagwiridwa.Pakhoma la nyumbayo, moyang'anizana ndi valavu yolowera ndi pabowo la ndodo, pali mabowo olowera ndi otuluka kuti alumikizane ndi makina a pneumatic.Komanso pa valve pali mpweya wokhala ndi valavu yake, yomwe imapereka mpumulo pamene ikukula kwambiri.
The divider actuation valve ili pafupi ndi clutch pedal kapena pafupi ndi hydraulic/pneumatic-hydraulic clutch booster mechanism.Pankhaniyi, mbali yotuluka ya tsinde la valavu (mbali yophimbidwa ndi fumbi fuse) imayang'anizana ndi kuyimitsidwa pa chopondapo chowongolera kapena pa clutch foloko drive pusher.
Valve ndi gawo la magawo osinthira zida zamagetsi, zomwe zimaphatikizaponso valavu yowongolera (pamagalimoto ena valavu iyi imayendetsedwa ndi chingwe, mwa ena imamangidwa mwachindunji mu lever ya gear), wogawa mpweya, valavu yochepetsera komanso diver shift drive molunjika.Cholowera cha valavu chimalumikizidwa ndi wolandila (kapena valavu yapadera yomwe imapereka mpweya kuchokera kwa wolandila), ndipo chotulukacho chimalumikizidwa ndi silinda ya pneumatic ya divider actuator kudzera pa wogawa mpweya (komanso kudzera mu valavu yochepetsera kuthamanga, yomwe kumalepheretsa kutuluka kwa mpweya kumbali ina).
Mapangidwe a divider actuation valve
Valavu yomwe ikufunsidwa ndi makina onse a pneumomechanical actuator ya divider amagwira ntchito motere.Kuti muchepetse kapena kupitilira, chogwirira chomwe chili pachiwopsezo cha giya chimasunthidwa kupita kumtunda kapena kumunsi - izi zimatsimikizira kugawanika kwa mpweya womwe umalowa mu wogawa mpweya (valavu yowongolera yomwe imalumikizidwa ndi chogwirizira imayambitsa izi), spool yake. chimayenda mbali imodzi kapena imzake.Panthawi ya kukanikiza kwakukulu kwa clutch pedal, valve actuation valve imayambika - valavu yake yolowera imatsegulidwa, ndipo mpweya umalowa m'mlengalenga, ndikudutsa mu pisitoni kapena pisitoni ya silinda ya pneumatic.Chifukwa cha kuchuluka kwa kupanikizika, pisitoni imasunthira kumbali ndikukokera chingwe kumbuyo kwake, chomwe chimasintha chogawanitsa ku gear yapamwamba kwambiri kapena yotsika kwambiri.Pamene clutch imatulutsidwa, valve imatseka ndipo wogawanika akupitiriza kugwira ntchito pamalo osankhidwa.Mukasintha chogawa kupita ku gear ina, njira zomwe zafotokozedwazo zimabwerezedwa, koma kutuluka kwa mpweya kuchokera ku valve kumapita kumalo otsutsana ndi silinda ya pneumatic.Ngati chogawa sichikugwiritsidwa ntchito posuntha magiya, ndiye kuti malo ake sasintha.
Ndikofunikira kuzindikira apa kuti valavu yamagetsi yogawa imatsegulidwa kumapeto kwa chiwopsezo cha pedal, pomwe cholumikizira chimathetsedwa kwathunthu - izi zimatsimikizira kusintha kwa zida zanthawi zonse popanda zotsatirapo zoyipa pamagawo opatsirana.Nthawi yomwe valavu imayatsidwa imayendetsedwa ndi malo a tappet ya ndodo yake yomwe ili pa pedal kapena pa tappet yolimbikitsa clutch.
Ndikofunikiranso kuwonetsa kuti valavu yophatikizira yogawa nthawi zambiri imatchedwa ma valve owongolera (ma switch) a makina osinthira zida omwe amapangidwa mu lever.Muyenera kumvetsetsa kuti izi ndi zida zosiyanasiyana zomwe, ngakhale zimagwira ntchito ngati gawo limodzi, zimagwira ntchito zosiyanasiyana.Izi ziyenera kuganiziridwa pogula zida zosinthira ndi kukonza.
Momwe mungasankhire bwino, m'malo ndi kukonza valavu yophatikizira yogawa
Panthawi yoyendetsa galimotoyo, galimoto yonse yoyendetsa galimotoyo ndi zigawo zake, kuphatikizapo valavu zomwe zafotokozedwa pano, zimakhudzidwa ndi zovuta zosiyanasiyana - kupanikizika kwa makina, kuthamanga, kuchitapo kanthu kwa nthunzi yamadzi ndi mafuta omwe ali mumlengalenga, ndi zina zotero. izi potsirizira pake zimabweretsa kuvala ndi kusweka kwa valve, zomwe zimabweretsa kuwonongeka kwa kayendetsedwe ka kayendetsedwe kake kapena kutaya kwathunthu kwa mphamvu yolamulira wogawanika.Valavu yolakwika iyenera kuthyoledwa, kupatulidwa kwathunthu ndikuzindikiridwa kuti ndi yolakwika, mbali zolakwika zitha kusinthidwa, ndipo pakawonongeka kwakukulu, ndi bwino kusintha gulu la valve.
Kuti mukonze valavu yophatikizira yogawa, mutha kugwiritsa ntchito zida zokonzekera zomwe zili ndi zida zomwe zimavalira kwambiri - valavu, akasupe, zinthu zosindikiza.Chombo chokonzekera chiyenera kugulidwa molingana ndi mtundu ndi chitsanzo cha valve.
Gear divider control drive
Mtundu ndi mtundu wokha (motsatira, nambala ya catalog) yomwe idayikidwa pagalimoto ndi wopanga wake ndiyomwe iyenera kusankhidwa kuti ilowe m'malo.Kwa magalimoto omwe ali pansi pa chitsimikizo, ili ndi lamulo (pogwiritsa ntchito zida zosinthira zomwe sizili zoyambirira zomwe zimasiyana ndi zomwe wopanga amalimbikitsa, mutha kutaya chitsimikizo), komanso kwa magalimoto akale, ndizotheka kugwiritsa ntchito ma analogue omwe ali ndi miyeso yoyenera yoyika. ndi makhalidwe (kukakamiza ntchito).
Kusintha kwa valve actuator yogawanitsa kuyenera kuchitidwa molingana ndi malangizo okonzekera ndi kukonza galimotoyi.Nthawi zambiri, kuti mugwire ntchitoyi, ndikofunikira kutulutsa mapaipi awiri kuchokera ku valavu ndikuchotsa valavu yokha, yomwe imagwiridwa ndi ma bawuti anayi (nthawi zina nambala yosiyana), ndikuyika valavu yatsopano motsatana.Kukonzanso kuyenera kuchitidwa pokhapokha ngati kukakamizidwa kwa pneumatic system kumasulidwa.
Vavu ikayikidwa, chowongolera chake chimasinthidwa, chomwe chimatsimikiziridwa ndikusintha malo oyimira ndodo yomwe ili pa clutch pedal kapena booster ndodo.Kawirikawiri, kusinthako kumapangidwa m'njira yakuti pamene chopondapo chowongolera chikukhumudwa kwambiri, pali mtunda wa 0.2-0.6 mm pakati pa tsinde loyenda malire ndi mapeto a chivundikiro cha valve (izi zimatheka mwa kusintha malo a tsinde stop).Kusintha kumeneku kuyeneranso kuchitidwa pakukonza chizolowezi chilichonse cha pneumomechanical gear shift system of the divider.Kuti musinthe, chotsani chivundikiro cha fumbi.
Panthawi yogwira ntchito, valavu imachotsedwa nthawi ndi nthawi, imachotsedwa ndikufufuzidwa, ngati kuli kofunikira, imatsukidwa ndi kupakidwa ndi mafuta apadera.Ndi kusankha koyenera ndi m'malo, komanso kukonza nthawi zonse, valavu idzagwira ntchito kwa zaka zambiri, kupereka kuwongolera molimba mtima kwa chogawa cha gearbox.
