Isixhobo esikhusela imoto okanye umqhubi ngexesha loxinzelelo loxinzelelo.
Kwiminyaka engamashumi amabini eyadlulayo, iibhampa zangaphambili nangasemva zeemoto zazenziwe ngezinto zesinyithi. Zazinyathelwe kwintsimbi yetshaneli enobume obungu-U enobukhulu obungaphezulu kwe-3mm. Umphezulu wawuphathwa nge-chrome kwaye waqhotyoshwa okanye wadityaniswa kunye nomqadi wesakhelo eside. Ngophuhliso lweshishini leemoto, i-bumper yemoto njengesixhobo esibalulekileyo sokhuseleko ikwayindlela yokuvelisa izinto ezintsha. Iibhampa zangaphambili nangasemva zeemoto zanamhlanje ukongeza ekugcineni umsebenzi wokuqala wokukhusela, kodwa kunye nokufuna ukuvumelana kunye nobunye nomzimba, ukufuna ukukhanya kwayo. Ukuze kufezekiswe le njongo, iibhampa zangaphambili nangasemva zeemoto zenziwe ngeplastiki, ezaziwa ngokuba ziibhampa zeplastiki. I-bumper sisixhobo sokhuseleko esifunxa kwaye sinciphise impembelelo yangaphandle kwaye sikhusele umphambili nomva womzimba wemoto. Kwiminyaka engamashumi amabini eyadlulayo, iibhampa zangaphambili nangasemva zeemoto zazenziwe kakhulu ngezinto zesinyithi. Zaqhotyoshwa kwintsimbi ye-U-channel enobukhulu obungaphezulu kwe-3mm. Umphezulu wawuphathwa nge-chrome kwaye waqhotyoshwa okanye waqhotyoshwa kunye nomzila wesakhelo. Ngophuhliso lweshishini leemoto, i-bumper yemoto njengesixhobo esibalulekileyo sokhuseleko ikwayindlela entsha. Ii-bumpers zangaphambili nezemva zemoto zanamhlanje ukongeza ekugcineni umsebenzi wokuqala wokukhusela, kodwa kunye nokufuna ukuvumelana kunye nobunye nomzimba, ukufuna ukukhanya kwayo. Ukufezekisa le njongo, ii-bumpers zangaphambili nezemva zemoto zenziwe ngeplastiki, ezaziwa ngokuba zii-bumpers zeplastiki. I-bumper yeplastiki yenziwe ngamacandelo amathathu, njengepleyiti yangaphandle, izinto zokuthambisa kunye nomqadi. Ipleyiti yangaphandle kunye nezinto zokuthambisa zenziwe ngeplastiki, kwaye umqadi wenziwe ngeshiti eqengqelekayo ebandayo enobukhulu obuyi-1.5 mm kwaye igximfizwe kwi-groove enomfanekiso we-U; Ipleyiti yangaphandle kunye nezinto zokuthambisa ziqhotyoshelwe kumqadi, oqhotyoshelwe kwi-screw yerail yesakhelo kwaye unokususwa nangaliphi na ixesha. Olu hlobo lwe-bumper yeplastiki lusebenzisa iplastiki, ngokuyintloko lusebenzisa uthotho lwe-polyester kunye nothotho lwe-polypropylene lwezixhobo ezimbini, kusetyenziswa indlela yokubumba ngenaliti. Kwamanye amazwe kukwakho uhlobo lweplastiki olubizwa ngokuba yi-polycarbon ester, ukungena kwi-alloy composition, indlela yokubumba i-alloy injection, ukucutshungulwa kwe-bumper akupheleli nje ekubeni nokuqina okuphezulu, kodwa kukwaneengenelo zokuwelda, kwaye ukusebenza kwe-coating kulungile, inani leemoto lininzi ngakumbi. I-bumper yeplastiki inamandla, ukuqina kunye nokuhombisa, ngokwembono yokhuseleko, ukungqubana kwemoto kunokudlala indima ye-buffer, kukhusele umzimba wemoto wangaphambili nowangasemva, ukusuka kwimbonakalo, kunokudityaniswa ngokwemvelo nomzimba kwisiqwenga, kudityaniswe kuyo yonke into, kuhonjiswe kakuhle, kube yinxalenye ebalulekileyo yembonakalo yemoto yokuhombisa.
