Ukuchaza iChamber yeSpring Brake kunye neDouble Diaphragm
I-Spring Brake Chamber yi-actuator eneenjongo ezimbini esetyenziswa kwii-axles zangasemva zeelori kunye neetreyila ukubonelela ngemisebenzi yokubhuleka kunye nemisebenzi yokungxamiseka/yokupaka. Ngokwesakhiwo, i-"Double Diaphragm" ibhekisa kuyilo lwangaphakathi oluthile lwegumbi lokubhuleka lentwasahlobo, apho ii-diaphragms ezimbini zerabha ezahlukeneyo zilawula amagumbi oxinzelelo lomoya ahlukeneyo.
Kwigama elisetyenziswa kwiimoto zorhwebo,Igumbi leeBrake zaseNtwasahloboidla ngokubhekisa kwindibano yonke, ngelixa i-"Double Diaphragm" ichaza uyilo lwayo lwangaphakathi loomatshini. Ezi yunithi zibalulekile kwimisebenzi "ekhuselekileyo", njengoko zisebenzisa intwasahlobo enamandla yangaphakathi yekhoyili ukufaka iibhuleki ukuba uxinzelelo lomoya lulahlekile, ukuqinisekisa ukuba imoto ihlala imile.
I-Anatomy yoLwakhiwo: Indlela Ezakhiwe Ngayo
Ulwakhiwo lwegumbi lanamhlanje leebhuleki zentwasahlobo eline-diaphragm ezimbini lwahlulwe lwaba ngamacandelo amabini aphambili: igumbi lenkonzo kunye negumbi leengxamiseko (lentwasahlobo). Igumbi lenkonzo, elikufutshane negumbiIsilungisi seSlack, iqulathe idiaphragm yokuqala ephendula xa isetyenziswa ipedali.
Icandelo elingasemva, elaziwa ngokuba yi-"piggyback" okanye icala elingxamisekileyo, ligcina intwasahlobo yokucinezelwa enzima kunye ne-diaphragm yesibini. Le diaphragm yesibini isebenza njengomqobo obamba intwasahlobo kwimeko yokucinezelwa kusetyenziswa uxinzelelo lomoya lwenkqubo. Ngokwemigangatho yeshishini efana ne-SAE J1469, ezi zinto kufuneka zimelane nemijikelo yoxinzelelo olugqithisileyo kunye nokubola kokusingqongileyo ukuqinisekisa ukuthembeka ebaleni.
