Chipinda Chosungira Mabuleki cha Spring vs Diaphragm Yawiri: Kapangidwe ndi Ntchito

Kumvetsetsa kusiyana kwa makina pakati pa Spring Brake Chamber ndi Double Diaphragm system ndikofunikira kwambiri kuti chitetezo ndi magwiridwe antchito a mabuleki a magalimoto akuluakulu amalonda asungidwe bwino. Buku lotsogolera ili likuwunika kapangidwe kake kapadera ndi ntchito za zigawozi mkati mwa brake circuit ya pneumatic, kupereka chidziwitso chaukadaulo cha gawo lokonzanso pambuyo pake.

Kufotokozera Chipinda Chosungira Mabuleki cha Spring ndi Diaphragm Yachiwiri

Spring Brake Chamber ndi chipangizo choyendetsera magalimoto chomwe chimagwiritsidwa ntchito pa ma axles akumbuyo a magalimoto akuluakulu ndi ma trailer kuti chipereke ntchito zonse ziwiri za brake komanso zadzidzidzi/zoyimitsa magalimoto. Mwa kapangidwe kake, "Double Diaphragm" imatanthauza kapangidwe ka mkati mwa chipinda cha brake cha spring, komwe ma diaphragm awiri osiyana a rabara amayendetsa zipinda zosiyanasiyana za mpweya woipa.

Mu mawu oti magalimoto amalonda, aChipinda Chosungira Mabuleki cha SpringNthawi zambiri amatanthauza gulu lonse, pomwe "Double Diaphragm" imafotokoza kapangidwe ka makina ake amkati. Magawo awa ndi ofunikira kwambiri pa ntchito "zotetezeka", chifukwa amagwiritsa ntchito kasupe wamphamvu wamkati kuti agwiritse ntchito mabuleki ngati mpweya watayika, kuonetsetsa kuti galimotoyo ikukhala yosasuntha.

Kapangidwe ka Kapangidwe: Momwe Amamangidwira

Kapangidwe ka chipinda chamakono chosungira mabuleki a masika cha diaphragm chagawidwa m'magawo awiri akuluakulu: chipinda chothandizira ndi chipinda chadzidzidzi (masika). Chipinda chothandizira, chomwe chili pafupi kwambiri ndiChosinthira cha Slack, ili ndi diaphragm yoyamba yomwe imayankha pedal ikagwiritsidwa ntchito.

Gawo lakumbuyo, lotchedwa "piggyback" kapena mbali yadzidzidzi, lili ndi kasupe wopondereza kwambiri ndi diaphragm yachiwiri. Diaphragm yachiwiriyi imagwira ntchito ngati chotchinga chomwe chimasunga kasupeyo mu mkhalidwe woponderezedwa pogwiritsa ntchito mpweya wa dongosolo. Malinga ndi miyezo yamakampani monga SAE J1469, zigawozi ziyenera kupirira kupanikizika kwakukulu komanso dzimbiri la chilengedwe kuti zitsimikizire kuti zikugwira ntchito bwino m'munda.

Mphamvu Yogwira Ntchito: Kugwira Ntchito ndi Kuyenda kwa Mpweya

Ntchito ya Spring Brake Chamber imadalira kayendetsedwe ka mpweya wopanikizika. Pa nthawi yoyendetsa bwino, mpweya umaperekedwa ku doko ladzidzidzi, kukankhira pa diaphragm yachiwiri kuti ikanikize "kasupe wamagetsi," womwe umamasula mabuleki.

Woyendetsa galimoto akagwiritsa ntchito pedali ya brake, mpweya umalowa mu doko la service port, ndikudzaza diaphragm yoyamba mu chipinda cha service. Mphamvu iyi imasuntha pushrod kuti izungulireChosinthira Chokhazikika Chokha, kenako n’kukanikizaPad ya Brakemotsutsana ndi ng'oma kapena diski. Kugwira ntchito kwapawiri kumeneku ndiko komwe kumatanthauza njira yogwirira ntchito ya "double diaphragm" m'magwiritsidwe ntchito amakono olemera.

Kusiyana Kwakukulu Pakati pa Mayunitsi Amodzi ndi Awiri a Diaphragm

Ngakhale chipinda chogwiritsira ntchito chokhazikika chimagwiritsa ntchito diaphragm imodzi, Spring Brake Chamber nthawi zambiri imakhala ndi diaphragm ziwiri. Chipinda chimodzi chogwiritsira ntchito diaphragm chimagwiritsidwa ntchito pokhazikitsa mabuleki (nthawi zambiri chimapezeka pama axles akutsogolo), pomwe chipinda chogwiritsira ntchito diaphragm ziwiri chimapereka mphamvu yofunikira poyimitsa magalimoto.

Deta yochokera ku Commercial Vehicle Safety Alliance (CVSA) ikusonyeza kuti kusakonza bwino diaphragm yachiwiri m'zipinda ziwiri ndi chifukwa chachikulu cholephera kuyang'anira msewu. Ngati diaphragm yachiwiri ikutuluka, kasupe wamagetsi angagwire ntchito pang'ono, zomwe zimayambitsa kukoka mabuleki, kutentha kwambiri, komanso moto womwe ungachitike chifukwa cha mawilo.

FAQ

Q1: Ndingadziwe bwanji ngati diaphragm yachiwiri ya chipinda changa cha mabuleki cha spring ikutuluka?

Kutuluka kwa mpweya mu diaphragm yachiwiri nthawi zambiri kumawonetsedwa ndi mpweya wotuluka nthawi zonse kuchokera ku doko lotulutsa utsi la valavu yowongolera dash kapena valavu yotulutsa mwachangu pamene mabuleki oimika magalimoto atulutsidwa. Izi zikusonyeza kuti mpweya ukudutsa chisindikizo chachiwiri kupita kumbali yautumiki kapena mlengalenga.

Q2: Kodi kusiyana pakati pa chipinda cha mtundu wa 30/30 ndi chipinda cha mtundu wa 24/30 ndi kotani?

Manambalawa akuyimira malo a mainchesi sikweya a ma diaphragm; Mtundu wa 30/30 uli ndi mainchesi 30 pa magawo onse a ntchito ndi masika, pomwe 24/30 imagwiritsa ntchito diaphragm yaying'ono ya mainchesi 24, yomwe imapereka mphamvu zochepa zogwirira ntchito koma imakhala ndi malo okwanira oimika magalimoto.

Q3: Kodi ndikotetezeka kusokoneza chipinda cha mabuleki a spring kuti mulowe m'malo mwa diaphragm imodzi?

Ayi, simuyenera kuyesa kutsegula mbali ya "yadzidzidzi" kapena kasupe wa chipinda chifukwa kasupe wamagetsi amphamvu kwambiri angayambitse kuvulala kwakupha. Akatswiri ayenera kungosintha diaphragm ya mbali yautumiki kapena kukhazikitsa "piggyback" yatsopano kapena chomangira.

Q4: N’chifukwa chiyani zipinda zina zimakhala ndi madoko a ndege okwana sikweya m’malo mozungulira?

Maboma a ndege okhala ndi mawonekedwe a sikweya ndiye chizindikiro chodziwika bwino cha zipinda zamabuleki za "Long Stroke". Magawo awa amalola kuyenda movutikira kwambiri mabuleki asanayambe kugwira ntchito bwino, zomwe ndi chitetezo chofunikira kwambiri m'makina amakono oyendetsera mabuleki apamwamba.

Q5: Kodi ma diaphragm omwe ali mu chipangizo cha diaphragm ziwiri ayenera kusinthidwa kangati?

Ngakhale palibe tsiku lokhazikika lotha ntchito, akatswiri amakampani amalimbikitsa kusintha ma diaphragm kapena chipinda chonse zaka zitatu kapena zisanu zilizonse, kutengera momwe zinthu zilili. Mavuto monga mchere wa pamsewu ndi kusinthasintha kwa kutentha kwambiri zimatha kufulumizitsa kuwonongeka kwa zinthu za rabara.
