Kunzwisisa musiyano wemakanika pakati peSpring Brake Chamber neDouble Diaphragm system kwakakosha pakuchengetedza kuchengetedzeka uye kushanda zvakanaka kwemabhureki emota dzekutengesa. Gwaro iri rehunyanzvi rinoongorora marongerwo akasiyana ezvimiro uye mabasa ezvikamu izvi mukati mecircuit yebhureki yepneumatic, zvichipa ruzivo rwehunyanzvi rwekugadzirisa mushure memusika.
Kutsanangura Spring Brake Chamber neDouble Diaphragm
Spring Brake Chamber inyanzvi yekufambisa mabhureki inoshandiswa pamagetsi ekumashure emarori nematrailer kuti ipe mabasa ekubhureki uye ekukurumidzira/emergency brake. Muchimiro, "Double Diaphragm" inoreva dhizaini chaiyo yemukati mekamuri remabhureki espring, uko ma diaphragm maviri akasiyana erabha anotarisira makamuri akasiyana ekumanikidzwa kwemhepo.
Mumashoko ekutengeserana emotokari, aKamuri reMabhureki eChituburinowanzoreva chinhu chose, nepo "Double Diaphragm" ichitsanangura magadzirirwo ayo emukati memotokari. Mayuniti aya akakosha pakushanda "kwakachengeteka", sezvo achishandisa chitubu chine simba chemukati checoil kuisa mabhureki kana mweya wakarasika, zvichiita kuti mota irambe yakamira.
Kuumbwa Kwechimiro: Mavakirwo Azvo
Chimiro chekamuri remazuva ano remabhureki echitubu rine diaphragm mbiri chakakamurwa kuita zvikamu zvikuru zviviri: imba yebasa nekamuri re emergency (spring). Imba yebasa, iri pedyo neChigadziriso cheSlack, ine diaphragm yekutanga inopindura kana pedal yaiswa.
Chikamu chekumashure, chinozivikanwa se "piggyback" kana kuti emergency side, chine chitubu chekumanikidza chinorema uye diaphragm yechipiri. Iyi diaphragm yechipiri inoshanda sechipingamupinyi chinobata chitubu mumamiriro ekumanikidzwa uchishandisa kumanikidzwa kwemhepo. Zvichienderana nemitemo yeindasitiri yakaita seSAE J1469, zvikamu izvi zvinofanirwa kutsungirira kumanikidzwa kwakanyanya uye ngura yezvakatipoteredza kuti zvive nechokwadi chekuti zvakavimbika mumunda.
Tafura 1: Kuenzanisa kweZvikamu zveMaumbirwo

Maitiro Ekushanda: Kushanda uye Kuyerera Kwemhepo
Basa reSpring Brake Chamber rinoenderana nekutonga kwakadzorwa kwemhepo yakamanikidzwa. Munguva yekutyaira kwakajairika, kumanikidzwa kwemhepo kunoendeswa kunzvimbo yekukurumidzira, kuchisundidzirana nediaphragm yechipiri kudzvanya "power spring," iyo inosunungura mabhureki.
Kana mutyairi akaisa pedal yebhureki, mweya unopinda muchiteshi chebasa, wobva wafuridza diaphragm huru iri mukamuri rebasa. Simba iri rinofambisa pushrod kuti itenderedzeChigadziriso cheSlack cheOtomatiki, iyo inobva yadzvanyaPad remabhurekipadhiramu kana dhisiki. Kushanda uku kweviri ndiko kunotsanangura mashandiro e "double diaphragm" mumashandisirwo emazuva ano ebasa guru.
Kusiyana Kwakakosha Pakati Pemayuniti Edhirafu Imwe Nekaviri
Kunyange zvazvo imba yekuchengetera zvinhu yakajairika ichishandisa diaphragm imwe chete, Spring Brake Chamber inenge iri imba yekuchengetera zvinhu zviviri. Imba yekuchengetera zvinhu imwe chete ndeyekushandisa mabhureki chete (inowanzowanikwa pama axles epamberi), nepo imba yekuchengetera zvinhu zviviri inopa simba rekushandisa pakupaka.
Ruzivo kubva kuCommercial Vehicle Safety Alliance (CVSA) runoratidza kuti kusagadziriswa zvakanaka kwediaphragm yechipiri mumakamuri maviri ndicho chikonzero chikuru chekukundikana kwekutarisa mumugwagwa. Kana diaphragm yechipiri ikadonha, chitubu chemagetsi chinogona kushanda zvishoma, zvichikonzera kudhonzwa kwemabhureki, kupisa zvakanyanya, uye moto unogona kuitika kumavhiri.
Tafura 2: Kuenzanisa Kwekushanda: Diaphragm Imwe Chete vs. Double Diaphragm

Basa reSipiringi reMagetsi muKuchengetedzwa kweEmergency
"Chitubu" chiri muSpring Brake Chamber isimbi hombe inokwanisa kushandisa simba rezviuru zvemapaunzi. Mukugadzirwa kwediaphragm mbiri, kumanikidzwa kwemhepo kunoshanda padiaphragm yechipiri ndiyo chete simba rinoita kuti chitubu ichi chidzoke.
Kana tireya ikatyoka kana kuti compressor yemhepo ikakundikana, kumanikidzwa kwemhepo kunodzikira, uye chitubu chinokura nekukurumidza. Iyi "emergency application" inodiwa nemutemo pasi peFMVSS 121 muUnited States uye mimwe mitemo yakafanana pasi rose. Nyanzvi dzinofanira kushandisa "caging bolt" kuti dzidzvinyirire chitubu ichi nemaoko vasati vagadzirisa pachirimo ichi.Caliper yebhurekikana kuti kamuri pachayo.

Maitiro Akanakisisa Ekuchengetedza Kwekugara Uchirarama Nguva Yakareba
Kuvimbika kwesystem ye double diaphragm kunoenderana nekusimba kwe rabha seal uye dziviriro yemukati me spring kubva kuhunyoro. Ngura ndiyo muvengi mukuru we brake chamber yechitubu, kazhinji zvichikonzera "ma springs akapwanyika" anogona kuboora diaphragm kana kudzvanya pushrod.
Kubvisa hunyoro nguva dzose mumatangi emhepo uye kuongorora mabhutsu eguruva ari paSirinda yeBreki yeVhiriNzvimbo iyi inogona kuwedzera hupenyu hwebasa remayuniti aya. Sekureva kweBendix Commercial Vehicle Systems, mabhureki emhepo anofanirwa kuongororwa kuti aone kana paine maburi uye matombo akatsemuka pakuchinja kwemafuta pese pamakiromita zviuru gumi kuti ive nechokwadi chekuti mota inoshanda zvakanaka.
Mhedziso: Kuenzanisa Kuchengetedzeka uye Mashandiro
Spring Brake Chamber, kuburikidza nekugadzirwa kwayo kwema diaphragm maviri, inoramba iri nzira yakavimbika yekudzivirira mota dzinorema. Nekuparadzanisa mabhureki ebasa nekupaka mota nekukurumidza kuita nzvimbo mbiri dzakasiyana dzemukati, mainjiniya vakagadzira sisitimu inokoshesa kuchengetedzeka kunyangwe paine kutadza kushanda kwemhepo. Kune vanofambisa ngarava nevanogadzirisa, kunzwisisa magadzirirwo aya ezvimiro ndiyo kiyi yekuchengetedza ngarava dzekutengeserana dzinotevedzera mitemo uye dzakachengeteka.
