Ukuqonda umehluko wemishini phakathi kwe-Spring Brake Chamber kanye nesistimu ye-Double Diaphragm kubalulekile ekugcineni ukuphepha nokusebenza kahle kwezinhlelo zokubhuleka kwezimoto zezentengiselwano ezisindayo. Lo mhlahlandlela wezobuchwepheshe uhlola ukwakheka okuhlukile kanye nezindima zokusebenza kwalezi zingxenye ngaphakathi kwesekethe yamabhuleki e-pneumatic, okunikeza ukuqonda kobungcweti komkhakha wokulungisa ngemuva kwemakethe.
Ukuchaza i-Spring Brake Chamber kanye ne-Double Diaphragm
I-Spring Brake Chamber iyi-actuator enezinjongo ezimbili esetshenziswa kuma-axle angemuva amaloli nama-trailer ukuhlinzeka ngemisebenzi yokubhuleka kanye neyezimo eziphuthumayo/zokupaka. Ngokwesakhiwo, i-"Double Diaphragm" ibhekisela ekwakhiweni kwangaphakathi kwegumbi lokubhuleka le-spring, lapho ama-diaphragm amabili erabha ahlukene ephatha amakamelo okucindezela umoya ahlukene.
Ngokwegama lezimoto zezentengiselwano, i-Igumbi Lokubhuleka Kwasentwasahloboivame ukubhekisela kuyo yonke inhlangano, kuyilapho elithi “Double Diaphragm” lichaza ukwakheka kwayo kwangaphakathi kwemishini. Lawa mayunithi abalulekile ekusebenzeni “okuphephile”, njengoba esebenzisa isipilingi esinamandla sangaphakathi sekhoyili ukufaka amabhuleki uma umfutho womoya ulahlekile, ukuqinisekisa ukuthi imoto ihlala ingashintshi.
I-Anatomy Yesakhiwo: Indlela Ezakhiwe Ngayo
Isakhiwo segumbi lesimanje lamabhuleki entwasahlobo eliphindwe kabili le-diaphragm sihlukaniswe izingxenye ezimbili eziyinhloko: igumbi lenkonzo kanye negumbi lezimo eziphuthumayo (intwasahlobo). Igumbi lenkonzo, eliseduze kakhulu negumbiIsilungisi se-Slack, iqukethe i-diaphragm yokuqala ephendula ekusetshenzisweni kwe-pedal.
Ingxenye yangemuva, eyaziwa ngokuthi “i-piggyback” noma uhlangothi oluphuthumayo, inesipilingi sokucindezela esinzima kanye ne-diaphragm yesibili. Le diaphragm yesibili isebenza njengesivikelo esibamba isipilingi esimweni sokucindezela kusetshenziswa umfutho womoya wesistimu. Ngokwezindinganiso zemboni ezifana ne-SAE J1469, lezi zingxenye kumele zimelane nemijikelezo yokucindezela okukhulu kanye nokugqwala kwemvelo ukuqinisekisa ukuthembeka ensimini.
