Isixhobo esinika isithinteli kwimoto okanye kumqhubi ngexesha loxinzelelo lwempembelelo.
Kwiminyaka engamashumi amabini eyadlulayo, iibumpers zemoto zangaphambili nasemva zazenziwe ikakhulu ngezinto zentsimbi. Zaye zagximfizwa kwintsimbi yentsimbi emile okwe-U enobunzima obungaphezulu kwe-3mm. Umphezulu waphathwa nge-chrome kunye ne-riveted okanye i-welded kunye ne-longitudinal beam yesakhelo. Ngophuhliso loshishino lweemoto, ibumper yemoto njengesixhobo esibalulekileyo sokhuseleko ikwasendleleni yokuqalisa izinto ezintsha. Imoto yanamhlanje ngaphambili kunye ne-bumpers yangasemva ukongeza ekugcineni umsebenzi wokukhusela wokuqala, kodwa kunye nokusukela imvisiswano kunye nobunye kunye nokumila komzimba, ukusukela ukukhanya kwayo. Ukuze kufezekiswe le njongo, i-bumpers yangaphambili kunye ne-bumpers yeemoto zenziwe ngeplastiki, ezibizwa ngokuba yi-plastiki bumpers.I-bumper sisixhobo sokhuseleko esithatha kwaye sinciphise impembelelo yangaphandle kwaye sikhusele umphambili kunye nomva womzimba wemoto. Kwiminyaka engamashumi amabini eyadlulayo, iibumpers zemoto zangaphambili nasemva zazenziwe ikakhulu ngezinto zentsimbi. Zaye zagximfizwa kwintsimbi ye-U-channel enobunzima obungaphezulu kwe-3mm. Umphezulu wawuphathwa nge-chrome kwaye i-riveted okanye idityaniswe kunye ne-rail frame. Ngophuhliso loshishino lweemoto, ibumper yemoto njengesixhobo esibalulekileyo sokhuseleko ikwasendleleni yokuqalisa izinto ezintsha. Imoto yanamhlanje ngaphambili kunye ne-bumpers yangasemva ukongeza ekugcineni umsebenzi wokukhusela wokuqala, kodwa kunye nokusukela imvisiswano kunye nobunye kunye nokumila komzimba, ukusukela ukukhanya kwayo. Ukufezekisa le njongo, ii-bumpers zemoto zangaphambili nasemva zenziwe ngeplastiki, ezaziwa ngokuba zii-bumpers zeplastiki. Ibhampa yeplastiki yenziwe ngamacandelo amathathu, afana nepleyiti yangaphandle, imathiriyeli yokuthomalalisa kunye nomqadi. I-plate yangaphandle kunye ne-buffer material yenziwe ngeplastiki, kwaye i-boam yenziwe ishidi elipholileyo elipholileyo elinobunzima obumalunga ne-1.5 mm kwaye ligxininiswe kwi-groove e-U-shaped; I-plate yangaphandle kunye nezinto zokucoca zifakwe kwi-beam, efakwe kwi-screw rail screw kwaye inokususwa nanini na. Olu hlobo lwebhampa yeplastiki isebenzisa iplastiki, ngokusisiseko isebenzisa uthotho lwepolyester kunye nothotho lwepolypropylene yezinto ezimbini, kusetyenziswa indlela yokubumba inaliti. Nangaphandle kukho uhlobo lweplastiki ebizwa ngokuba yi-polycarbon ester, ukungena kwi-alloy composition, indlela yokubumba inaliti ye-alloy, ukusetyenzwa ngaphandle kwe-bumper akugcini nje ngokuba namandla aphezulu, kodwa kunenzuzo yokuwelda, kunye nokusebenza kokugquma kulungile. ubuninzi nangakumbi emotweni. I-bumper yeplastiki inamandla, ukuqina kunye nokuhombisa, ukusuka kwindawo yokhuseleko lokujonga, ukungqubana kwemoto kunokudlala indima ye-buffer, ukukhusela umzimba wemoto wangaphambili nangemuva, ukusuka kwinkangeleko, unokudibanisa ngokwemvelo kunye nomzimba kwisiqwenga, ukudibanisa iyonke, inomhombiso olungileyo, ibe yinxalenye ebalulekileyo yembonakalo yemoto yokuhombisa.
