Umthwalo wemfanelo oyinhloko webhampa ukuvikela abahamba ngezinyawo: ngoba abahamba ngezinyawo bangabantu abasengozini, ibhampa yepulasitiki inganciphisa amandla okushayisana emilenzeni yabahamba ngezinyawo, ikakhulukazi amathole, ngomklamo ofanele webha yangaphambili, kunciphisa izinga lokulimala lapho abahamba ngezinyawo beshaywa.
Okwesibili, isetshenziselwa ukunciphisa ukulahlekelwa yizingxenye zemoto lapho kushayisana isivinini. Uma i-bumper ingaklanywanga kahle, umonakalo kulezi zingxenye ungaba mkhulu lapho kushayisana.
Kungani amabhampa enziwe ngepulasitiki futhi egcwele igwebu?
Eqinisweni, i-bumper ngempela yayakhiwe ngensimbi kudala, kodwa kamuva kwatholakala ukuthi umsebenzi we-bumper ngokuyinhloko ukuvikela abahamba ngezinyawo, ngakho-ke kungokwemvelo ukushintsha ibe yipulasitiki.
Eminye imisebe yensimbi engashayisani izombozwa ngengqimba yefoam, okuzogcwalisa igebe eliphakathi kwe-resin bumper kanye ne-steel engashayisani, ukuze i-bumper ingabi "thambile" kangako uma ingaphandle, umphumela wangempela ungesivinini esiphansi kakhulu, amandla amancane kakhulu, ungakhululeka ngqo ekunakekelweni.
Uma ibhampa liphansi, izindleko zokulungisa ziphakeme:
Uma umklamo webhampa uphakeme, izindleko zokulungisa ziyancipha, ngokusho kombiko we-IIHS. Izimoto eziningi ngenxa yomklamo ophansi kakhulu webhampa, lapho ishayisana ne-SUV, iloli lokuthutha aliyona indima yokuvimba, umonakalo wezinye izingxenye zemoto nawo ukhulu kakhulu.
Izindleko zokulungisa i-bumper yangaphambili ziphakeme kunezindleko zokulungisa i-bumper yangemuva ziphakeme kakhulu kunezindleko zokulungisa i-bumper yangemuva.
Esinye ukuthi i-bumper yangaphambili ifaka izingxenye eziningi zemoto, kuyilapho i-bumper yangemuva ifaka kuphela izingxenye ezinenani eliphansi njengezibani zangemuva, amapayipi okukhipha umoya kanye neminyango ye-trunk.
Okwesibili, ngenxa yokuthi amamodeli amaningi aklanyelwe ukuba aphansi ngaphambili futhi aphakame ngemuva, i-bumper yangemuva inenzuzo ethile ngokuphakama.
Amabhampa okushaya ngamandla aphansi angabhekana nokushaya, kuyilapho amabhampa okushaya ngamandla aphezulu edlala indima yokudlulisa amandla, ukuhlakazeka kanye nokubopha, futhi ekugcineni adluliselwe kwezinye izakhiwo zomzimba, bese ethembela emandleni esakhiwo somzimba ukuze amelane naso.
IMelika ayibheki i-bumper njengokulungiswa kokuphepha: I-IIHS eMelika ayibheki i-bumper njengokulungiswa kokuphepha, kodwa njengokwesekwa kokunciphisa ukulahlekelwa ukushayisana ngesivinini esiphansi. Ngakho-ke, ukuhlolwa kwe-bumper kusekelwe emcabangweni wokuthi unganciphisa kanjani izindleko zokulahlekelwa nokugcinwa. Kunezinhlobo ezine zokuhlolwa kokushayisana kwe-bumper ye-IIHS, okuyizivivinyo zokushayisana zangaphambili nangemuva (isivinini esingu-10km/h) kanye nokuhlolwa kokushayisana ngaphambili nangemuva (isivinini esingu-5km/h).
