Impilo yokudluliselwa kwezithuthi kwizithuthi zorhwebo ixhomekeke kakhulu ekuchanekeni kwezinto ze-electro-pneumatic. Esi sikhokelo sichonga iimpawu zokuqala zesilumkiso seevalvu ze-solenoid ze-gearbox ezingasebenziyo kwaye sibonelela ngamanyathelo okulungisa asebenzayo ukuqinisekisa ukuthembeka kweenqwelo kunye nokunciphisa ixesha lokungasebenzi kwizicelo ezinzima.
Ukuqonda Indima YeeValve ZeGearbox Solenoid
Ivalvu ye-solenoid yebhokisi yegiya isebenza njengomlindi wesango we-electro-mechanical, iyalela umoya oxinzelelweyo okanye ulwelo lwe-hydraulic ukuba lubambe iigiya ezithile kunye nee-clutches ngaphakathi kwe-transmission yesithuthi sorhwebo. Kwimeko yeelori ezinkulu kunye neebhasi, ezi valve zibalulekile ekusebenzeni kakuhle kwe-Automated Manual Transmissions (AMT). Ukuqonda indlela ezisebenza ngayo ezi nxalenye linyathelo lokuqala ekuchongeni ukuguguleka kwangaphambi kwexesha ngaphambi kokuba kukhokelele ekungasebenzi kakuhle kwenkqubo.
Ii-solenoids zeGearbox zifumana imiqondiso yombane evela kwi-Transmission Control Unit (TCU), ziguqula ezi zinto zifakwayo zibe yintshukumo yoomatshini. Xa ivalvu iqala ukungasebenzi, ulungelelwaniso phakathi kwamandla enjini kunye nokukhethwa kwegiya yothumelo luyaphazamiseka. Kubaphathi beenqwelo-mafutha abafumana kumthengisi wezixhobo zezithuthi zorhwebo, ukuchonga ezi ngxaki kwangethuba kubalulekile ekulawuleni izinto ezisetyenzisiweyo ngendlela engabizi kakhulu.
Iimpawu eziphambili zeValve zeGearbox Solenoid ezingasebenzi kakuhle
Eyona nto ixhaphakileyo ebonisa ukuba i-solenoid yegiya ayisebenzi kakuhle kukutshintshatshintsha okungaqhelekanga, njengokubandakanyeka kwegiya okulibazisekileyo okanye "ukuzingela" phakathi kwegiya. Oku kwenzeka xa i-plunger yangaphakathi ye-solenoid ibambeka okanye i-coil ye-electromagnetic ilahlekelwa kukumelana kwayo okuchaziweyo. Ukuba umqhubi uxela ukuba imoto iyasokola ukuhla phantsi komthwalo, i-solenoid enoxanduva lolo luhlu lwegiya isenokuba sengozini.
Esinye isilumkiso esibalulekileyo kukusebenza "kwemo yokulibaziseka", apho i-TCU ithintela ukudluliselwa kwigiya enye ukuthintela umonakalo ongakumbi woomatshini. Le meko yokukhusela idla ngokubangela iiKhowudi zeNgxaki zokuHlola (ii-DTC) ezithile ezinxulumene nokuqhubeka kwesekethe okanye ummiselo woxinzelelo. Amaqela obuchwephesha olondolozo kufuneka abeke phambili ukujonga uluhlu lweValve yeGearbox Solenoid xa ezi zilumkiso ze-elektroniki zivela kwideshibhodi.

Uhlalutyo lobuchwephesha: Kutheni iiValve zeSolenoid zingaphumeleli
Izinto ezisingqongileyo kunye nongcoliseko lolwelo zezona zinto ziphambili ezibangela ukuwohloka kwe-solenoid kwizicelo zezithuthi zorhwebo. Kwiilori ezininzi ezinzima, unikezelo lomoya lunokuba nezixa ezincinci zokufuma okanye i-oyile carbonization, nto leyo edala "umgxobhozo" ngaphakathi kwevalvu. Le nkunkuma yonyusa ukumelana koomatshini, inyanzela i-solenoid ukuba itsale umbane omninzi ize ekugqibeleni itshise ii-windings zombane.
Ngaphezu koko, ukujikeleza kobushushu—ukufudumeza nokupholisa rhoqo kwebhokisi yegiya—ekugqibeleni kubangela ukuba izinto zeplastiki okanye zerabha ezikwivalvu zibe buthathaka. Izinto ezisemgangathweni ophezulu ezivela kwinkampani ethembekileyo.Inkqubo yeBrake yoMoya yeLoriabavelisi benzelwe ukumelana nobushushu obugqithisileyo. Nangona kunjalo, neevalvu ezilungileyo zinobomi bomjikelo omiselweyo, zihlala zilinganiswa phakathi kwesigidi esinye ukuya kwizigidi ezi-5 ze-actuations kuxhomekeke kuyilo oluthile.
Amanyathelo okuxilonga kwiingcali zeenqanawa
Iingcali kufuneka ziqale inkqubo yokuxilonga ngokwenza uvavanyo lokuxhathisa kwiiphini ze-solenoid zisebenzisa i-digital multimeter. Uninzi lwee-solenoids zorhwebo ezingama-24V kufuneka zibonise uluhlu oluthile lokuxhathisa (ngokuqhelekileyo phakathi kwe-12 ukuya kwi-80 ohms, kuxhomekeke kwimodeli). Ukufundwa kwe-zero kubonisa i-short circuit, ngelixa ukufundwa okungapheliyo kubonisa i-open circuit, zombini ezifuna ukutshintshwa kwevalvu ngokukhawuleza.
Inqanaba lesibini lokuxilongwa libandakanya uvavanyo lokuhla koxinzelelo. Ngokusebenzisa umoya olawulwayo kwi-solenoid kunye nokujonga ukuphuma kwayo nge-pressure gauge, iingcali zinokubona ukuba ivalvu ayidluli umoya ngaphakathi. Ukusebenzisa ikhithi yokuxilonga yeTransmission Control Valve esemgangathweni ophezulu kunokunceda ukufumanisa ukuba ingxaki ikwi-solenoid ngokwayo okanye kwi-wiring harness ekhokelela kwi-TCU.
