Iitreyila kunye nee-semi-trailer zixhotyiswe nge-air brake system esebenza ngekonsathi kunye neziqhoboshi zetrektara.Ukulungelelaniswa kokusebenza kweenkqubo kuqinisekiswa ngumthengisi womoya ofakwe kwi-trailer / i-semi-trailer.Funda konke malunga nale yunithi, iintlobo zayo, uyilo kunye nokusebenza kwinqaku.
Yintoni itreyila/isemi-trailer yebrake diffuser?
Umsasazi womoya weebhuleki zenqwelwana / i-semi-trailer (ivalve yokuhambisa umoya) licandelo lolawulo kunye nolawulo lwenkqubo yeebhuleki zeenqwelwana kunye ne-semi-trailer ene-pneumatic drive.Iyunithi enenkqubo yee-ducts kunye neevalve eziqinisekisa ukuhanjiswa komoya oxinzelelweyo phakathi kwamacandelo enkqubo.
Umsasazi womoya uyilelwe ukulawula uloliwe wendlela kunye netreyila eyahlukileyo / isemi-trailer:
• Ukuqhawuka iziqhoboshi zetreyila / isemi-trailer njengenxalenye kaloliwe wendlela;
• Ukuqhawuka kwetreyila / isiqingatha setreyila xa uqhawukile kwinqwelo;
• Ukukhululwa kwetreyila / isiqingatha setreyila ukuba kukho imfuneko, iyaqhuba ngaphandle kokuncamathela kwitrektara;
• Uqhankqalazo olungxamisekileyo lwenqwelwana / isemi-trailer xa isahlula kuloliwe wendlela.
Zonke iinqwelwana zemithwalo kunye ne-semi-trailer zixhotyiswe ngabasasazi be-brake air, kodwa ziyahluka ngenjongo, uhlobo kunye noyilo, olufuna ukuchazwa ngokubanzi.
Iintlobo kunye nokusebenza kwee-diffusers ze-brake
Abasasazi bomoya bahlulahlulwe ngamaqela ngokohlobo lwe-actuator ye-pneumatic ye-brake system apho banokusebenza khona, kunye noqwalaselo.
Kukho iintlobo ezintathu ze-air diffusers:
• Kwiinkqubo zokuqhobosha ngocingo olunye;
• Kwiinkqubo zokuqhoboshwa kweentsimbi ezimbini;
•Kujikelele.
Iibhuleki zocingo olulodwa lweetrailer kunye ne-semi-trailer zixhunywe kwinkqubo ye-pneumatic yemoto kunye ne-hose enye.Ngoncedo lwayo, zombini ukuzaliswa kwabamkeli be-trailer / i-semi-trailer kunye nokulawulwa kweebhuleki zayo zenziwa.Iinkqubo zokuqhawula iintambo ezimbini zixhunyiwe kwinkqubo ye-pneumatic yetrektara ngemigca emibini - ukutya, apho abamkeli be-trailer bagcwaliswa, kunye nokulawula.
Ukusebenza kwinkqubo yokuqhawula ucingo olulodwa, abahambisa umoya kunye nesixhobo sokulandela umkhondo basetyenziswa, ebeka iliso kuxinzelelo emgceni kwaye, ngokuxhomekeke kuyo, unikezela umoya oxinzelelweyo osuka kummkeli wetreyila ukuya kumagumbi ayo okubhuleka.
Ukusebenza kwinkqubo yeentambo ezimbini, kusetyenziswa abasasazi bomoya abanendlela eyahlukileyo yokulandela umkhondo, ebeka iliso kuxinzelelo kumgca wolawulo, kwaye, ngokuxhomekeke kuyo, ilawula ukuhanjiswa komoya kubamkeli ukuya kumacandelo enkqubo yebrake. inqwelo erhuqwayo / isemi-trailer.I-Universal air diffusers inokusebenza kwiinkqubo zokuqhobosha ngocingo olunye kunye nolwesibini.
Ngokobumbeko, kukho iindidi ezimbini zabasasazi bomoya:
• Ngaphandle kwezixhobo ezongezelelweyo;
• Ngevalve yokukhululwa eyakhelwe-ngaphakathi (KR).
Kwimeko yokuqala, umthengisi womoya uquka kuphela amacandelo abonelela ngokusasazwa ngokuzenzekelayo komoya ocinezelweyo kuyo yonke inkqubo, kuxhomekeke kuxinzelelo lwenkqubo ye-pneumatic yetrektara (okanye kumgca wolawulo).Ukukhululwa kunye ne-braking ye-trailer / i-semi-trailer ekhutshwe kuloliwe wendlela, ivalve yokukhulula esetyenziswa ngesandla isetyenzisiweyo, enokufakwa ecaleni komsasazi womoya okanye kumzimba wayo.Kwimeko yesibini, umthengisi womoya une-valve eyakhelwe ngaphakathi.
Uyilo kunye nomgaqo wokusebenza kwee-diffusers ze-brake
Namhlanje, ziveliswa inani elikhulu leemodeli zevalve yokuhambisa umoya yeetreyila kunye ne-semi-trailer, kodwa zonke zinesixhobo esifanayo.Iyunithi idibanisa iipiston ezininzi kunye neevalvu ezitshintsha umgca ukusuka kwitrektara, i-receiver kunye ne-wheel brake chambers, ngokuxhomekeke kwimeko yesixokelelwano seziqhoboshi zetrektara.Makhe siqwalasele uyilo kunye nomgaqo-siseko wokusebenza kwendawo yonke (esetyenziswa kwiinkqubo zombini kunye ne-2-wire brake systems) umsasazi womoya weetreyila ze-KAMAZ ezinevalve yokukhulula eyahlukileyo.
Qaphela nje ukuba umsasazi womoya ulawula inkqubo yebrake yetreyila kuphela xa usebenzisa eyona nkqubo yokuqhobosha yetrektara.Ukuba isitshixo okanye isistim seziqhoboshi zokupakisha sisetyenziswa kwitrektara, umoya wokubonelelwa kumalungu enkqubo yeziqhoboshi ezirhuqwayo kulawulwa ngevalve yesolenoid.Asiyi kuqwalasela umsebenzi wale node apha.
Ukusebenza komthengisi womoya kwisekethe yocingo olulodwa lwenkqubo ye-pneumatic
Isixhobo somthengisi womoya jikelele
Umgca ovela kwi-pneumatic system yetrektara uqhagamshelwe kumbhobho I;I-Nozzle II ihlala ikhululekile kwaye idibanisa inkqubo emoyeni;umbhobho III uqhagamshelwe kumagumbi okuqhawula;I-Pin IV - kunye nomamkeli wetreyila.Ngolu xhulumaniso, umbhobho weV uhlala ukhululekile.
Umzobo wenkqubo yomoya yocingo olunye
Umgca ovela kwi-pneumatic system yetrektara uqhagamshelwe kumbhobho I;I-Nozzle II ihlala ikhululekile kwaye idibanisa inkqubo emoyeni;umbhobho III uqhagamshelwe kumagumbi okuqhawula;I-Pin IV - kunye nomamkeli wetreyila.Ngolu xhulumaniso, umbhobho weV uhlala ukhululekile.
Ukudityaniswa kwetreyila kunye netrektara.Intshukumo kaloliwe wendlela.Kule ndlela, umoya oxinzelelweyo ovela kumgca wemoto ngombhobho ndingena kwigumbi le-piston 2, udlula kwi-cuff skirt 1 kwaye ungene ngokukhululekileyo kwigumbi le-piston, ngokusebenzisa umjelo ungena kumbhobho IV kwaye ukusuka kuwo ukuya kubamkeli.Ivalve yokukhupha i-5 ihlala ivulekile, ngoko ke amagumbi okuqhawula anxibelelana nomoya ngombhobho III, ivalve 5, umkhono wayo 6 kunye nombhobho II.Ke, ngelixa uqhuba njengenxalenye yololiwe wendlela, abafumana i-trailer / i-semi-trailer bazaliswa, kwaye iibhuleki azisebenzi.
Ukunyanyiswa kukaloliwe wendlela.Ngomzuzu wokuqhawula itrektara, uxinzelelo kumgca kunye nombhobho ndiyahla.Ngexesha elithile, uxinzelelo oluvela kwicala lombhobho IV (ukusuka kubamkeli be-trailer / i-semi-trailer) ludlula uxinzelelo oluvela kwicala lombhobho I, imiphetho ye-cuff icinezelwe ngokuchasene nomzimba we-cavity kunye nepiston. , ukoyisa i-elasticity ye-spring 9, ihamba phantsi.Kunye nepiston 2, intonga 3 kunye nepiston esezantsi 4 ehambelana nayo ishukuma, isihlalo sevalve yokugqibela 5 sikufuphi nobuso besiphelo somkhono 6, siphinde sihla kwaye sivule ivalve yokungena 7. Ngenxa yoko, Umoya ocinezelekileyo ovela kubamkeli betreyila / isemi-trailer ngombhobho we-IV ungena kumbhobho we-III ukuya kumagumbi okuqhawuka - iziqhoboshi zevili ziyashukunyiswa kwaye ukuqhawuka kwenzeka.
Ukutshatyalaliswa kololiwe wendlela.Xa itrektara ikhutshwa, uxinzelelo kumbhobho I ukwanda, ngenxa yoko, umbhobho I kwakhona iqhagamshelwe kumbhobho IV (abamkeli trailer zizaliswe), kunye namagumbi brake wopha umoya ngokusebenzisa imibhobho III kunye II - ibraking iyenzeka.
Uqhankqalazo olungxamisekileyo kwimeko yokwaphuka kombhobho, ukuqhawulwa kwetreyila / isiqingatha setreyila kuloliwe wendlela.Kuzo zombini ezi meko, uxinzelelo kwi-terminal II yehla ukuya kuxinzelelo lwe-atmospheric kwaye umsasazi womoya usebenza njengakwi-braking eqhelekileyo.
Ukusebenza komhambisi womoya kunye neskimu socingo olumbini lomthengisi womoya
Umzobo wenkqubo ye-pneumatic eneengcingo ezimbini
Imigca emibini esuka kwi-trekta ixhunyiwe kwi-distributor air - ukubonelela kumbhobho I kunye nokulawula kumbhobho V. Imibhobho eseleyo inonxibelelwano olufana nesekethe yocingo olulodwa.Kwakhona, ngesekethe ye-2-wire pneumatic actuator, ivalve yokulinganisa i-10 iqala ukusebenza.Ngesi sikimu soxhulumaniso, uxinzelelo oluphezulu lusetyenziswa kumbhobho I kunokuba kunye nesekethe yocingo olulodwa, okwenza kube nzima ukuhambisa i-piston 2 kunye nokuphazamisa ukusebenza kwayo yonke inkqubo ye-braking.Le ngxaki ikhutshwe yi-valve yokulinganisa - kuxinzelelo oluphezulu, ivula kwaye idibanise imingxuma ngaphezulu nangaphantsi kwepiston, ilinganisa uxinzelelo kubo.
Ukudityaniswa kwetreyila / isiqingatha setreyila kunye netrektara.Intshukumo kaloliwe wendlela.Kule meko, umoya ovela kwi-hose yokubonelela ngeepayipi ze-I kunye ne-IV zigcwalisa abamkeli, amacandelo asele okusabalalisa umoya azisebenzi.
Ukunyanyiswa kukaloliwe wendlela.Xa itrektara ibhulekiwe, uxinzelelo luyenyuka kumbhobho we-V, umoya ocinezelweyo ungene kwigumbi elingentla kwepiston 11, ubangele ukuba iye ezantsi.Kule meko, iinkqubo ezichazwe ngasentla zenzeke - i-valve 5 ivala, i-valve 7 ivula, iipayipi IV kunye ne-III zixhunyiwe, kwaye umoya ovela kubamkeli ungena kumagumbi okuqhawula, ukunyathela.
Ukutshatyalaliswa kololiwe wendlela.Xa itrekta ikhutshwa, zonke iinkqubo zenzeka ngokulandelelana: uxinzelelo kumbhobho we-V wehla, i-piston iphakama, umbhobho we-III uqhagamshelwe kumbhobho II, umoya ovela kumagumbi okuqhawula ukhululwe kwaye i-trailer ikhululwe.
Ukunyanzeliswa kwe-emergency xa kukho ikhefu emgceni, ukuqhawulwa kwe-trailer.Kule meko, indima yendlela yokulandelela iqhutywe yi-valve yokulinganisa.Xa uxinzelelo kwipayipi ye-II iyancitshiswa kuxinzelelo lwe-atmospheric, i-valve ivala, ihlukanise amagumbi angaphezulu nangaphantsi kwepiston 2. Ngenxa yoko, uxinzelelo olungaphezulu kwepiston (ngenxa yomoya ovela kubamkeli ngepayipi ye-IV) ukwanda, kunye neenkqubo ezifana ne-braking zenzeke ngeskim soqhagamshelo locingo olunye.Ngaloo ndlela, xa ithumbu laphukile / liqhawulwe okanye xa uloliwe wendlela echithwa, i-trailer / i-semi-trailer iqhobosheka ngokuzenzekelayo.
Uyilo kunye nomgaqo wokusebenza kwevalve yokukhulula
I-CD inesakhiwo esilula kunye nokusebenza.Qwalasela ukusebenza kwale yunithi kumzekelo weetreyila zeekhreyini ze-Kama Automobile Plant.
Iyunithi inokufakwa ngokuthe ngqo kumzimba wokusabalalisa umoya okanye ibekwe ecaleni kwayo kwindawo efanelekileyo ngakumbi.Umbhobho wayo Ndiqhagamshelwe kumamkeli wetreyila / isiqingatha setreyila ngejelo losasazo lomoya okanye ngombhobho owahlukileyo.I-Nozzle II ixhunywe kumfana I we-distributor air, kwaye ipayipi III ixhunyiwe kumgca oyintloko wemoto.
Ngexesha eliphambili lokusebenza kwe-trailer, intonga ye-1 ikwindawo ephezulu (igxininiswe kule ndawo ngokusebenzisa iibhola ezilayishwe entwasahlobo eziphumle ngokubhekiselele kwi-recesses emzimbeni wesixhobo), umoya ophuma emlonyeni. I-III ingena kumbhobho we-II, kwaye i-terminal I ihlala ivaliwe, ngoko i-valve ayichaphazeli ukusebenza komthengisi womoya.
Ukuba kuyimfuneko ukuhambisa i-trailer evaliweyo, kufuneka uhambise intonga ye-1 phantsi ngoncedo lomqheba - oku kuya kukhokelela ekuhlukaneni kwemibhobho ye-II kunye ne-III kunye nokudityaniswa kwemibhobho II kunye ne-I. Ngenxa yoko, i umoya ovela kummkeli uqondiswe kwi-inlet I yokusabalalisa umoya, uxinzelelo oluphezu kwayo luphakama kwaye iinkqubo zenzeke ezifanayo kwiinkqubo zokuqhoqhobala kunye nesekethe enye yocingo lwe-pneumatic drive - i-trailer ikhululwa.Ukunyathela, kuyimfuneko ukubuyisela intonga kwindawo ephezulu.
Isixhobo sevalve yokukhulula
Ukukhethwa, ukutshintshwa kunye nokugcinwa kwe-diffuser ye-brake
Umsabalalisi womoya we-brake uhlala ephantsi kwemithwalo ephezulu, izikhewu zanda kwiindawo zayo ezihambayo, ezinokubangela ukuvuza komoya, ukuwohloka kokusebenza okanye, ngokuchaseneyo, ukusebenza ngokuzenzekelayo kweebhuleki.Kwimeko nayiphi na ingxaki, kunengqiqo ukutshintsha indibano yendibano.
Xa ukhetha umthengisi womoya, kufuneka ukhokelwe iingcebiso zomenzi we-trailer, kwaye ufake iiyunithi zeemodeli ezithile kunye namanani ekhathalogu.Nangona kunjalo, namhlanje imarike inikezela uluhlu olubanzi lwabasasazi bomoya bokuqala kunye nee-analogue zabo ezineempawu eziphuculweyo.Ngoko ke, kwezinye iimeko, kuyafaneleka ukufaka i-analogue, kodwa ukuze ugweme iingxaki kwixesha elizayo, kufuneka ukhethe ama-analogues kunye nemilinganiselo efanelekileyo yokudibanisa kunye neempawu.
Ngokukhetha okufanelekileyo kunye nokufakwa kwe-distributor air, iibhuleki ze-trailer okanye i-semi-trailer ziya kusebenza ngokuthembekileyo nangempumelelo kuzo zonke iimeko, ukuqinisekisa ukhuseleko lomzila wesitimela.
