Kunzwisisa mashandiro chaiwo ekuverenga mabhureki emhepo anorema mukamuri remabhazi makuru kwakakosha pakuona kuchengetedzeka uye kushanda zvakanaka kwemabhureki emotokari dzekutengesa. Gwaro iri rine humbowo hwepamusoro rinopa ruzivo rwakadzama rwekuti ungaverenga sei simba rekuburitsa uye kusarudza saizi chaiyo yekugadzirisa nekutsiva mushure memusika.
Tsanangudzo yeAir Brake Chamber Thrust
Kusundidzira kwemukamuri wemabhureki isimba remuchina rinogadzirwa nemhepo yakamanikidzwa inoshanda padiaphragm inochinjika mukati meimba yekamuri yemabhureki. Muhurongwa hwekubhureki hweS-cam hwakajairika, simba iri rinopfuudzwa kuburikidza netsvimbo kuenda kuchinogadzirisa slack, izvo zvinozoshandura kufamba kuita torque yekuisa shangu dzemabhureki padhiramu. Hukuru hwekusundidzira uku hunosarudza simba rekumisa rinogoneka kubhasi rinorema.
Fomura yemasvomhu yekuverenga thrust
Kuverenga kwakakosha kwesimba rekubuda kwemukamuri remabhureki emhepo kunotevera mutemo wepanyama wekumanikidzwa kwakawedzerwa nenzvimbo (F=P×A).kamuri remabhureki, nzvimbo inoshanda inoonekwa nehukuru hwe diaphragm, iyo inorongwa nenhamba dze "Rudzi" dzinomiririra nzvimbo mu square inches.
Fomura:
Kupinza (lbs)=Kumanikidzwa Kwemhepo (psi)×Nzvimbo Inoshanda yeDiaphragm (sq. in.)
Semuenzaniso, kamuri remhando ye30 rinoshanda nepressure yakajairwa ye100 psi rinogadzira 3,000 lbs chaiyo yekusundidzira (30 sq. in. × 100 psi). Zvichienderana neSangano rekuchengetedza mota dzekutengesa (CVSA), kuchengetedza kurohwa kwakakodzera kwe pushrod uye kumanikidzwa kwakakosha, sezvo chero kutsauka kunogona kutungamira mukutyorwa kwemutemo "kunze kwebasa" panguva yekuongorora.
Chati Yekukura Kwemakamuri Emabhazi Anorema Ane Mabhureki Emhepo
Kusarudza saizi chaiyo kunoda kufananidza nzvimbo inoshanda yekamuri nezvinodiwa nemugadziri wemidziyo yemotokari (OEM) kuti mabhureki arambe akaenzana. Mabhazi mazhinji anorema anoshandisa mhando 24, mhando 30, kana mhando 36 zvichienderana nehuremu hwe axle.

Zvinhu Zvinokanganisa Kubuda Kwesimba Rechokwadi Munyika
Kurasikirwa kwekushanda zvakanaka kwemuchina uye kuramba kwechitubu kunofanirwa kuverengerwa pakuverenga simba remagetsi rinounzwa kucaliper yebhurekikana zvikamu zveS-cam. Kunyange zvazvo fomura yedzidziso ichipa hwaro hwekutanga, maspring ekudzoka emukati anowanzo dya anenge 50 kusvika 100 lbs ekusundidzira kwekutanga. Uyezve, sezvo pushrod stroke ichiwedzera, kona inoshanda ye slack adjuster inochinja, zvichigona kuderedza torque inoshandiswa pabrake camshaft.
Kuenzanisa Makamuri eDiaphragm Ari Mumwe Chete neMakamuri Aviri
Makamuri ebasa (diaphragm imwe chete) anopa simba rekubhureka chete kana achishandiswa pedal, nepo makamuri ebhureka espring (diaphragm mbiri) aine chitubu chine simba chekukurumidzira/kupaka. Mugadziriro yediaphragm mbiri, "Power Spring" inopa mukana wekusashanda zvakanaka; kana kumanikidzwa kwemhepo kwakaderera pasi peinenge 60 psi, chitubu chinokura kuti chishandise mabhureka otomatiki. Kuti chitsiviwe, kuve nechokwadi chekutivharafu ye solenoidKugadzirisa utsi hwemhepo nemazvo mumakamuri aya kwakakosha pakusunungura mabhureki ekupaka.
Kunzwisisa Miganhu yeStroke uye Margins ekuchengetedza
Saizi yega yega yekamuri remabhureki ine "kurovera kwakarongwa" uye "muganho wekugadzirisazve" usingafanirwe kupfuurwa kuti uve nechokwadi chekusundidzira kwakanyanya. Kana pushrod ikaenda kure zvakanyanya (inozivikanwa se "bottoming out"), diaphragm inogona kurasikirwa nesimba rayo rinoshanda, zvichikonzera kudzikira kukuru kwesimba remabhureki. Ruzivo rweindasitiri kubva kuindasitiri kubva kuMasisitimu eMotokari dzeMabhizinesi eBendixzvinoratidza kuti inenge 25% yekukundikana kwekutarisa mugwagwa kunokonzerwa nekugadziriswa kwemabhureki zvisina kunaka kana kuti kurovera kwakawedzerwa nguva.

|---|---|---|
| Rudzi 20 | 1.75 inches | 2.0 inches |
| Rudzi 24 | 1.75 inches | 2.0 inches |
| Rudzi rwe30 | 2.0 inches | 2.5 inches |
Gwaro Rekusarudza Kutsiva Mabhureki Ebhazi
Pakutsvaga zvikamu kubva kusisitimu yemabhureki eroriMupi wemotokari, gara uchiongorora nzvimbo yebhoti rinosungirirwa uye kureba kwetsvimbo yekufambisa pamwe chete nerudzi rwemukamuri. Mabhazi anorema anowanzo da mhando dze "Long Stroke" dzerudzi rwe30 chamber kuti dzive nekuchengetedzwa kwakanyanya kubva pakudonha kwemabhureki. Kushandisa chamber yakajairwa yestroke uko kunoda kurohwa kwenguva refu kunogona kutungamira mukurasikirwa nemabhureki nguva isati yakwana panguva yekudzika kwegomo kana mumamiriro ekupisa kwakanyanya.
Mhedzisiro yeKumanikidzwa kweMhepo paNzvimbo yeBraking
Kupeta kaviri kumanikidzwa kwemhepo kunowedzera kaviri kusundidzirwa, asi sisitimu inofanira kuverengerwa kuti ikwanise kubata mitoro yakadaro pasina kukanganisa kwechikamu. Masisitimu mazhinji emhepo anorema anoshanda pakati pe100 ne125 psi; zvisinei, panguva yekubhureka kwekukurumidzira,pedhi rebhurekikumanikidzwa kwacho kwakaenzana zvakananga nekumanikidzwa kwemukamuri kunogadzirwa panguva iyoyo. Federal Motor Vehicle Safety Standards (FMVSS 121) taura daro diki rekumira iro kukosha kwekusundidzira uku kunofanirwa kusvika pahuremu hwakasiyana hwemotokari.
Maitiro Ekugadzirisa Kuti Uwane Simba Rakanaka
Kuongorora nguva dzose mitsetse yendege uyesirinda huru yekubata(muma transmissions emaoko) inoita kuti system yese yepneumatic irambe yakasimba inodiwa kuti ikwanise kusundirwa zvizere. Matekiniki anofanira kushandisa nzira yakarongwa kuti aone kuti mativi ese e axle anowana kumanikidzwa kwakaenzana, sezvo kusawirirana kwekusundirwa kwe10% kunogona kukonzera bhazi kudhonza parutivi panguva yekubhureka zvakanyanya, zvichikanganisa kuchengetedzeka kwevatakuri.
Pfupiso yehunyanzvi yezvinodiwa paSaizi
Mukupfupikisa, kukura kwekamuri remabhazi anorema kunoda kuziva Rudzi (Nzvimbo), kusimbisa Stroke (Standard vs. Long), uye kuona kuti hardware yekumisikidza inoenderana nebracket ye axle. Kuverenga kwakakodzera kunoita kuti mukana wemuchina unopihwa ne slack adjuster uwedzere, zvichiita kuti mota irambe iri mukati memiganhu yekuchengetedzwa kwemutemo.
Mibvunzo Inowanzo bvunzwa
Ndingaziva sei saizi yekamuri rangu remabhureki ebhazi kana chikwangwani chisipo?
Unogona kuziva saizi yacho nekuyera dhayamita yekunze yekamuri iri pakati pebhandi rekusimbisa. Semuenzaniso, kamuri reType 30 rinowanzova nedhayamita yekunze inosvika masendimita masere. Tichitarisa chati yepamutemo yehukuru kubva kuDare reTekinoroji neKugadzirisa (TMC)zvinogona kubatsira kusimbisa zviyero izvi.
Ndingatsiva imba yerudzi rwe24 neimba yerudzi rwe30 here kuti ndiwane simba rakawanda?
Kuwedzera saizi yekamuri pasina mvumo yeinjiniya kune njodzi sezvo zvichiita kuti mabhureki asawirirane. Kamuri rakakura pane imwe axle richaita kuti mavhiri iwayo avharwe nekukurumidza kupfuura mamwe, zvichikonzera kutsvedza kana kupwanywa nebanga. Gara uchitevedzera mhando yakatarwa neOEM yebhazi rako.
Musiyano uripo pakati pe "nzvimbo inoshanda" ne "nzvimbo isina kunyorwa" ndeupi?
Nzvimbo ine nhamba yakatenderera (serudzi rwe30), nepo nzvimbo inoshanda iri masendimita chaiwo anoshandiswa nemhepo panguva yekurohwa. Kunyange zvazvo ichiwanzoonekwa seyakafanana pakuverenga, kupera kwe diaphragm kunogona kuderedza zvishoma nzvimbo inoshanda mumakore akati wandei ekushanda munzvimbo dzakaoma.
Kupisa kunokanganisa sei kusundidzirwa kwekamuri remabhureki emhepo?
Kutonhora kwakanyanya kunogona kuomesa diaphragm yerabha, zvichiwedzera kumanikidzwa kunodiwa kuti ikunde kuramba kwekutanga. Kusiyana neizvi, kupisa kwakanyanya kubva mumadhiramu kunogona kukonzera "kudzima kwebhureki," uko zvikamu zvemuchina zvinokura, zvichida kuroverwa kwenguva refu kuti zvisvike pakusundidzira kwakafanana. Ndokusaka makamuri ekuroverwa kwenguva refu achifarirwa mabhazi anorema.
Sei kona ye pushrod ichikosha pakuverenga thrust?
Kuverenga simba rekushandisa simba remagetsi kunokuudza simba remagetsi, asi "simba rinoshanda" rinoenderana nekuti pushrod iri pakona ye90-degree kune slack adjuster panzvimbo yekushandisa brake. Kana kona iri pamusoro kana pasi pe90 degrees, chikamu chepush chinotambisa, zvichideredza torque chaiyo yekubhureka.
