Izindinganiso ze-AAR M-215 zesistimu yokuxhumanisa

Ulwazi oluyisisekelo

Uhlelo lokugoqa ama-coupler oluhambisana nezindinganiso ze-AAR (Association of American Railroads) luyithuluzi elibalulekile lokuxhumanisa nokuhlanganisa umthelela phakathi kwezimoto. Lolu hlelo luqukethe ama-coupler, amagiya okudonsa kanye nama-jokes. Okokuqala, i-coupler iyisici esibalulekile sokuxhumanisa imoto. Yenziwe ngensimbi enamandla kakhulu, enamandla aphezulu kanye nomthamo wokuthwala umthwalo ngemva kokucutshungulwa okunembile kanye nokwelashwa kokushisa. I-coupler ihlangabezana nezidingo zezinga le-AAR, futhi ingaxhumanisa imoto ngokuqinile ngesikhathi sokudonswa, ukubhuleka kanye nokuxhumeka, ukuqinisekisa ukuzinza nokuphepha kwesitimela.

Okwesibili, i-shock absorber iyithuluzi elibalulekile lokumunca ukushaqeka phakathi kwezimoto. I-buffer ingamunca futhi isabalalise ngempumelelo amandla okushaya phakathi kwezimoto ngedivayisi yayo yangaphakathi ye-buffer. Ngokwezinga le-AAR, i-buffer idinga ukuba nomthamo omkhulu we-buffer kanye nekhono lokululama ngokushesha ukuqinisekisa ukushelela kanye nenduduzo yesitimela esisebenzayo.

Okokugcina, ijoka yilona elisetshenziswa ukubopha nokulengisa igiya lokudonsa. Amajoka enziwe ngensimbi enamandla amakhulu ukuze amelane nesisindo kanye nokushayisana kwebhampa. Umklamo wejoka kumele uhlangabezane nezidingo zezinga le-AAR ukuqinisekisa ukuthi lixhunywe ngokuqinile nangokuthembekile ku-coupler kanye ne-buffer, futhi kuvimbele ukukhululeka noma ukuwa ngesikhathi sokusebenza.

Ngamafuphi, uhlelo lwe-buffer lokuhlanganisa izimoto zesitimela oluhambisana nezinga le-AAR luyingxenye ebalulekile yokuqinisekisa ukuphepha nokuzinza kwethrafikhi yesitimela. Lwakhiwe yizingxenye ezifana nama-couplers, amagiya okudonsa kanye nama-jokes, angaxhumanisa futhi avimbele amandla okushaya phakathi kwezimoto ngempumelelo. Zonke lezi zingxenye zidinga ukuhlangabezana nezidingo zezinga le-AAR ukuqinisekisa ukuthembeka nokuphepha kohlelo ekusebenzeni kwezimoto.
