Ukuhambanana nezindlela zokuphepha kwezomthombo zokuphepha zaseFederale

Isibonelo se-FMVSS No. 206 ngamaphetha amadoda nezinqakamba zokugcina

Amaphakathi amadodwa kufanele abhekise ukuthi izihluzi zabo zokuvula ziyafanele kubona imithombo ye-FMVSS No. 206, okusho ukuthi kufanele badeze izikhumba zokuvula zokudla ezingavuli ngokungafanele xa kunezinkinga. Ngokwemithombo emisha yase-2023, lezi zikhumba zokuvula kufanele zibekwe ngokuphambuka kwamandla amaningi—ngokwesibonelo, amashumi amathathu ayisifanayo nendawo yokuqala yezinkundla zokugcina phakathi kwezinye izindawo zokugcina ngokuphambuka kwezinye izindawo. Lokhu kuyasebenza kuzo zonke izindawo zokuvula eziphakathi kwezinhloso. Kodwa izinto ziyagcinwa kancane kuma-dla zokuvula ezihluzi, ngoba zinamaphakathi amaningi okukhuluma ngokuphambuka kwamandla ngokuphambuka kwezinye izindawo, okwenza ukuthi umsebenzi wokudeza kuyahlinzekile kuma-dla zokuvula eziphakathi.

Imithombo Yezikhumba Zokuvula Kuma-dla Eziphakathi Namadla Ama-Sliding Ngaphansi Kwe-FMVSS

Amalatchi wezinyawo zokuvula ezinamaphakade kufanele zibe nesibonelo sezindawo zokusebenza ngokuphakeme kwe-11,000 Newtons lapho kuyisibonelo sezindawo zokusebenza. Amalatchi amabili ayizindawo zokusebenza angafana nazo kodwa kufanele zifanele nezimboni zokusebenza zokugcina ngokuphakeme kwe-9,000 Newtons ngokwemithombo yokuqondisa i-FMVSS okubhekene nalo bonke abantu bakhuluma ngayo. Manje kuzinyawo zokuslide kunezimboni ezinye zokusebenza. Abahleli bezinto kufanele bakhombise ukuthi izinyawo zabo zinamandla okungqina umthambeka wokuphakama okulingana nomkhulu wokuphakama kwizinyawo ngokuphakeme kwe-1.5. Kungani lokhu kubalulekile? Lokhu kubalulekile kakhulu ngoba kugcina izinyawo ukuzivula ngokungafanele emaphakameni njengokugcina kokugcina ngokuphakeme noma lapho izihlathi ziyagcina. Amadonga okuphakama okwenziwa ngokugcina kuyakwenzela ukuthi kubhekene nokukhula kwezinyawo zomkhakha, ngakho-ke ukunika amalatchi amandla okugcina akhethekile kuyakwenzela ukuthi abantu bakhona ngempilo ngaphakathi komkhakha.

Izindlela zokuzimisa Amalatchi wezinyawo Ngokwesibonelo sezindawo zokusebenza Noma Ngokwesibonelo sezindawo zokusebenza

Ukuzimisa okuhlanganisiwe kwezimboni zokusebenza kusebenzisa ukuzimisa kwezinyangala ezintathu:

1. Ukuzimisa Kwesibonelo sezindawo zokusebenza : Sebenzisa amandla okuphakama/okuhorizontal ukuze uzimele izinhlobo zokugcina
2. Imithambo Yokugcina Ngokushesha Kwemithambo Yekhanda : Kuphinda ukuthi kubhekwe imithambo yokuqhubeka kwesikhathi sokugcina ngokushesha kwe-48 km/h
3. Imithambo Yokuzimela Ngokuphinda-phinda : Imiphinda engu-100,000 yokuvula/nokufuna ukuhlola imithambo yokuvala

Le ndlela yombili yokubhekisa imithambo yokuqhubeka kwesikhathi sokugcina ngokushesha nokuthi ibe yisikhathi eside kusiza ukuthi izinkulungwane zokugcina kwemoto zihlanganise nezidingo zokuphepha kwezimali zokuphepha kwemoto.

Ukuthi Ukuthenga Kwemoto Kukhethekile Kanjani Ukuthi Kuhlanganise Nezidingo Zokuphepha Kwesikhathi Sokugcina Kwemoto
