Inani leelori zale mihla zixhotyiswe ngezahluli - iibhokisi zegiya ezikhethekileyo eziphinda kabini inani leegiya zothumelo.I-divider ilawulwa yi-valve ye-pneumatic - funda malunga nale valve, ukuyila kwayo kunye nokusebenza kwayo, kunye nokukhethwa ngokuchanekileyo, ukutshintshwa kunye nokugcinwa kwevalve kweli nqaku.
Yintoni ivalve yokuvula isahluli?
Ivalve ye-actuation yesahluli yiyunithi yenkqubo ye-pneumomechanical gear shift yesahluli selori;ivalve ye-pneumatic ebonelela ngokutshintshela kude kwesahluli sebhokisi yegiya ngokunikezela umoya kumthengisi kunye ne-cylinder ye-pneumatic yamandla okwangoku i-clutch ikhutshiwe ngokupheleleyo.
Kwiimodeli ezininzi zeelori zasekhaya nezangaphandle, i-gearbox ixhotyiswe ngesahluli-ibhokisi yegiya yenqanaba elinye, eliphinda kabini inani elipheleleyo leegiya zokuhambisa.Isahluli sandisa kakhulu amandla ebhokisi yegiya, sinyusa ukuguquguquka kokuqhuba kwiimeko ezahlukeneyo zendlela naphantsi kwemithwalo eyahlukeneyo.Ulawulo lwale yunithi kwiinqwelo ezininzi zenziwa ngokusetyenziswa kwenkqubo ye-pneumomechanical divider gear shift, enye yeendawo ezibalulekileyo kule nkqubo ibanjwe yi-valve yokufaka i-valve.
Ivalve ye-actuation yesahluli yenza umsebenzi omnye ophambili: ngoncedo lwayo, umoya ocinezelekileyo osuka kwinkqubo ye-pneumatic unikezelwe kwisilinda samandla sepneumatic ye-dider gear shift mechanism ebekwe kwi-crankcase yebhokisi yegiya.Ivalve iqhagamshelwe ngokuthe ngqo kwi-clutch actuator, eqinisekisa ukuba i-dider gears itshintshiwe xa i-pedal ye-clutch icinezele ngokupheleleyo kwaye ngaphandle kokuphathwa okongeziweyo kwicala lomqhubi.Ukusebenza okungalunganga kwevalve okanye ukungaphumeleli kwayo ngokuyinxenye okanye kuphazamisa ngokupheleleyo ukusebenza kwesahluli, esifuna ukulungiswa.Kodwa ngaphambi kokulungisa okanye ukutshintsha le valve, kuyimfuneko ukuqonda ukuyila kwayo kunye neempawu zokusebenza.
Isixhobo kunye nomgaqo wokusebenza kweevalve zokutshintsha kwi-dider
Zonke iivalvu zokuhlukanisa ezisetyenziswayo namhlanje zinoyilo olufanayo ngokomgaqo.Isiseko seyunithi yintsimbi yentsimbi kunye nomjelo wexesha elide kunye nezinto zokunamathisela iyunithi kumzimba okanye kwezinye iindawo zemoto.Ngasemva komzimba kukho i-valve yokungena, kwindawo ephakathi kukho i-cavity ene-valve stem, kwaye kwindawo yangaphambili umzimba uvalwe ngesiciko.Intonga idlula kwikhava kwaye idlulele ngaphaya kwendlu, apha ihlanganiswe nesigqubuthelo serubha esingenathuli (i-fuse fuse), apho kubanjwe umda wokuhamba ngentsimbi.Kudonga lwendlu, ngokuchasene ne-valve yokungena kunye ne-cavity yentonga, kukho imingxuma yokungena kunye ne-outlet yokudibanisa kwinkqubo ye-pneumatic.Kwakhona kwivalve kukho into yokuphefumla enevalve yayo, ebonelela ngokukhululeka koxinzelelo xa ikhula kakhulu.
Ivalve ye-actuation yesahluli ibekwe nokuba isecaleni kwe-clutch pedal okanye ecaleni kwe-hydraulic/pneumatic-hydraulic clutch booster mechanism.Kule meko, indawo ephumayo yesiqu sevalve (kwicala eligqunywe ngefuse yothuli) ijongene nendawo yokumisa kwi-pedal clutch okanye kwi-clutch fork drive pusher.
Ivalve yinxalenye yenkqubo yokutshintsha igiya yohlulo, ekwabandakanya ivalve yokulawula (kwezinye iimoto le valve ilawulwa yintambo, kwezinye yakhiwe ngokuthe ngqo kwi-lever gear), umsasazi womoya, ivalve yokunciphisa uxinzelelo kunye i-diver shift drive ngqo.I-inlet yevalve idityaniswe kumamkeli (okanye ivalve ekhethekileyo enikezela umoya kummkeli), kwaye i-outlet idityaniswe ne-cylinder ye-pneumatic ye-actuator ye-dider ngokusebenzisa i-distributor yomoya (kwaye ukongeza nge-valve yokunciphisa uxinzelelo, leyo kuthintela ukuvuza komoya kwicala elichaseneyo).
Uyilo lwevalve yokuvula isahluli
Ivalve ekuthethwa ngayo kunye ne-actuator yonke ye-pneumomechanical yomsebenzi we-dider ngolu hlobo lulandelayo.Ukubandakanya ukunciphisa okanye ukugqithisa, isiphatho esibekwe kwi-lever yegiya sishukunyiswa kwindawo ephezulu okanye ephantsi - oku kuqinisekisa ukuhanjiswa kwakhona kokuhamba komoya okungena kwi-distributor air (i-valve yokulawula ehambelana nesibambo inoxanduva loku), i-spool yayo. ishukuma iye kwelinye icala okanye kwelinye.Ngeli xesha loxinzelelo oluphezulu lwe-clutch pedal, ivalve ye-actuation ye-dider iyaqala-ivalve yayo yokungena iyavula, kwaye umoya ungene kwi-distributor yomoya, kwaye ngayo ungene kwipiston okanye i-piston cavity ye-cylinder ye-pneumatic.Ngenxa yokunyuka koxinzelelo, i-piston itshintshela kwicala kwaye idonsa i-lever emva kwayo, etshintsha i-dider ukuya kwindawo ephezulu okanye ephantsi.Xa i-clutch ikhutshwe, i-valve ivala kwaye isahluli siyaqhubeka sisebenza kwindawo ekhethiweyo.Xa utshintshela isahluli kwenye i-gear, iinkqubo ezichazwe ziphindaphindiwe, kodwa ukuhamba komoya kwi-valve kubhekiswe kwisigxina esichasene ne-cylinder ye-pneumatic.Ukuba isahluli asisetyenziswanga xa utshintsha iigiya, ke indawo yayo ayitshintshi.
Kubalulekile ukuba uqaphele apha ukuba i-valve ye-actuator ye-dider ivula kuphela ekupheleni kwe-pedal stroke, xa i-clutch ikhutshwe ngokupheleleyo - oku kuqinisekisa utshintsho oluqhelekileyo lwezixhobo ngaphandle kwemiphumo emibi kwiindawo zokuhambisa.Umzuzu uvulwa kwevalve ulawulwa yindawo ye tappet yentonga yayo ebekwe kwi pedal okanye kwi clutch booster tappet.
Kwakhona kuyimfuneko ukubonisa ukuba i-valve yokubandakanya i-valve ihlala ibizwa ngokuba yi-valve yokulawula (iiswitshi) zendlela yokutshintsha i-gear eyakhelwe kwi-lever.Kufuneka uqonde ukuba ezi zixhobo ezahlukeneyo ezithi, nangona zisebenza njengenxalenye yenkqubo efanayo, zenza imisebenzi eyahlukeneyo.Oku kufuneka kuthathelwe ingqalelo xa kuthengwa iinxalenye ezisecaleni kunye nokulungiswa.
Indlela yokukhetha ngokufanelekileyo, ukubuyisela kunye nokwenza ukugcinwa kwe-valve yokubandakanya isahluli
Ngexesha lokusebenza kwesithuthi, yonke i-diver control drive kunye namacandelo ayo ngamnye, kubandakanywa ivalve exoxwa apha, ibonakaliswe kwiimpembelelo ezahlukeneyo ezingalunganga - uxinzelelo lomatshini, uxinzelelo, isenzo somphunga wamanzi kunye namafutha aqulethwe emoyeni, njl. oku ekugqibeleni kukhokelela ekugqokeni nasekuqhekekeni kwevalve, okubangela ukuwohloka kokusebenza kwenkqubo okanye ukulahlekelwa ngokupheleleyo kwamandla okulawula isahluli.I-valve ephosakeleyo kufuneka ikhutshwe, ihlakazwe ngokupheleleyo kwaye ixhomekeke ekubonweni kwephutha, iindawo eziphosakeleyo zinokuthi zitshintshwe, kwaye kwimeko yokuphazamiseka okukhulu, kungcono ukutshintsha i-valve assembly.
Ukulungisa i-valve yokufaka i-valve, ungasebenzisa iikhithi zokulungisa eziqukethe iindawo ezinxibe kakhulu - i-valve, imithombo, izinto zokutywina.Ikiti yokulungisa kufuneka ithengwe ngokuhambelana nohlobo kunye nomzekelo wevalve.
Gear umahluli wolawulo drive
Kuphela uhlobo kunye nemodeli (ngokulandelelanayo, inombolo yekhathalogu) efakwe kwisithuthi ngumenzi wayo kufuneka ikhethelwe ukutshintshwa.Kwiimoto eziphantsi kwewaranti, lo ngumgaqo (xa usebenzisa iinxalenye ezingezizo ezoqobo ezahlukileyo kwezo zicetyiswa ngumenzi, unokuphulukana newaranti), kwaye kwizithuthi ezindala, kunokwenzeka ukuba kusetyenziswe ii-analogues ezinobungakanani obufanelekileyo bokufaka. kunye neempawu (uxinzelelo lokusebenza).
Ukutshintshwa kwevalve ye-actuator ye-divider kufuneka kuqhutywe ngokuhambelana nemiyalelo yokulungisa kunye nokugcinwa kwesi sithuthi.Ngokuqhelekileyo, ukwenza lo msebenzi, kuyimfuneko ukukhupha iipayipi ezimbini kwi-valve kunye nokuqhaqha i-valve ngokwayo, ebanjwe ezine (ngamanye amaxesha inani elihlukeneyo) leebholiti, kwaye ufake i-valve entsha ngokulandelelana.Ukulungiswa kufuneka kuqhutywe kuphela emva kokukhutshwa kwengcinezelo kwinkqubo ye-pneumatic.
Emva kokuba i-valve ifakwe, i-actuator yayo ihlengahlengiswa, eqinisekiswa ngokutshintsha indawo yokumisa intonga ebekwe kwi-pedal clutch okanye i-booster rod.Ngokuqhelekileyo, uhlengahlengiso lwenziwa ngendlela yokuba xa i-clutch pedal icinezeleke ngokupheleleyo, kukho umgama we-0.2-0.6 mm phakathi kwe-stem limiter yokuhamba kunye nobuso bokuphela kwesivalo sevalve (oku kufezekiswa ngokuguqula indawo ukuma kwesiqu).Olu lungelelaniso kufuneka lwenziwe kugcino ngalunye lwesiqhelo lwenkqubo ye-pneumomechanical gear shift ye-divider.Ukwenza uhlengahlengiso, susa isigqubuthelo sothuli.
Ngethuba lokusebenza okulandelayo, i-valve isuswe ngamaxesha, idibaniswe kwaye ihlolwe, ukuba kuyimfuneko, ihlanjwe kwaye ifakwe i-lubricated nge-grease composition ekhethekileyo.Ngokukhetha okufanelekileyo kunye nokutshintshwa, kunye nokugcinwa rhoqo, i-valve iya kusebenza iminyaka emininzi, inika ulawulo oluthembekileyo lwesahluli sebhokisi.
