Olona xanduva lwe-bumper kukukhusela abahambi ngeenyawo: ngenxa yokuba abahambi ngeenyawo bangamaqela asengozini, i-bumper yeplastiki inokunciphisa amandla eempembelelo kwimilenze yabahambi ngeenyawo, ngakumbi amathole, ngoyilo olufanelekileyo lwebha yangaphambili, ukunciphisa iqondo lokulimala xa abahambi ngeenyawo behamba. hit.
Okwesibini, isetyenziselwa ukunciphisa ilahleko yamalungu esithuthi kungquzulwano lwesantya. Ukuba ibhampa ayilungiswanga kakuhle, umonakalo kwezi ndawo unokuba mbi kakhulu kwingozi.
Kutheni iibumpers zeplastiki kwaye zizaliswe ngamagwebu?
Enyanisweni, i-bumper ngokwenene yenziwe ngentsimbi kwakudala, kodwa kamva kwafunyaniswa ukuba umsebenzi we-bumper ikakhulu ukukhusela abahambi ngeenyawo, ngoko kuyindalo ukutshintshela kwiplastiki.
Eminye imiqadi yentsimbi enobungqina bokuphahlazeka iya kugqunywa ngomaleko we-foam, okuzalisa umsantsa phakathi kwe-resin bumper kunye nentsimbi yobungqina bentsimbi, ukuze i-bumper ingabi "thambile" ngaphandle, umphumo wangempela. Ikwisantya esiphantsi kakhulu, amandla amancinci kakhulu, inokukhululeka ngokuthe ngqo kulondolozo.
Okukhona isezantsi ibhampa, kokukhona zinyuka iindleko zokuyilungisa:
Ukuphakama kwe-bumper design, iphantsi kweendleko zokulungisa, ngokutsho kwengxelo ye-IIHS. Iimoto ezininzi ngenxa yoyilo oluphantsi kakhulu lwe-bumper, xa ukungqubana ne-SUV, ilori yemoto ayiyondima ye-buffer, umonakalo wezinye iindawo zesithuthi nawo mkhulu.
Iindleko zokulungisa ibhampa yangaphambili ziphezulu kuneendleko zokulungisa ibhampa yangasemva ziphezulu kakhulu kuneendleko zokulungisa iibhampa zangasemva.
Enye yeyokuba i-bumper yangaphambili ibandakanya iindawo ezininzi zemoto, ngelixa i-bumper yangasemva ibandakanya kuphela izinto ezinexabiso eliphantsi ngokwentelekiso njengezibane zasemva, imibhobho ye-exhaust kunye neengcango ze-trunk.
Okwesibini, kuba iimodeli ezininzi zenzelwe ukuba ziphantsi ngaphambili kwaye ziphakame ngasemva, i-bumper yangasemva inenzuzo ethile ekuphakameni.
Amandla aphantsi ama-bumpers anempembelelo angakwazi ukujamelana nempembelelo, ngelixa ii-bumpers zempembelelo ezinamandla aphezulu zidlala indima yokuhanjiswa kwamandla, ukusabalalisa kunye nokukhusela, kwaye ekugqibeleni ukudluliselwa kwezinye izakhiwo zomzimba, kwaye emva koko zixhomekeke kumandla esakhiwo somzimba ukuxhathisa. .
I-Amerika ayithathi i-bumper njengendlela yokukhusela: i-IIHS eMelika ayithathi i-bumper njengendlela yokukhusela ukhuseleko, kodwa njenge-accessory yokunciphisa ilahleko ye-low-speed collision. Ke ngoko, uvavanyo lwe-bumper lukwasekwe kumbono wendlela yokunciphisa ilahleko kunye neendleko zokugcina. Kukho iintlobo ezine zeemvavanyo ze-IIHS ze-bumper crash, ezizimvavanyo zengozi ngaphambili nangasemva (i-speed 10km/h) kunye novavanyo lwengozi yangaphambili nangasemva (isantya se-5km/h).
