Iyo bumper chishandiso chekuchengetedza chinotora uye kurerutsa maitiro ekunze uye inodzivirira kumberi nekumashure kwemuviri wemotokari. Makore makumi maviri apfuura, mabhampa epamberi uye kumashure emotokari ainyanya kugadzirwa nesimbi. Vakadhindwa muU-channel simbi ine ukobvu hunodarika 3mm. Iyo yepamusoro yakabatwa ne chrome uye yakashongedzwa kana kubatanidza pamwe chete nenjanji. Nekuvandudzwa kweindasitiri yemotokari, bumper yemotokari sechinhu chakakosha chekuchengetedza chiri munzira yekuvandudza. Mazuva ano mota kumberi uye kumashure mabumpers mukuwedzera pakuchengetedza iyo yekutanga kuchengetedza basa, asiwo kutsvaga kuwirirana uye kubatana nechimiro chemuviri, kutsvaga kwayo kureruka. Kuti uite chinangwa ichi, kumberi uye kumashure mabumpers emotokari anogadzirwa nepurasitiki, inozivikanwa sepurasitiki bumpers. Iyo purasitiki bumper inoumbwa nezvikamu zvitatu, senge rekunze ndiro, cushioning zvinhu uye danda. Iyo yekunze ndiro uye buffer zvinhu zvakagadzirwa nepurasitiki, uye danda rakagadzirwa nechando chakakungurutswa pepa rine ukobvu hunosvika 1.5 mm uye rakadhindwa mugororo rakaumbwa neU; Iyo yekunze ndiro uye cushioning zvinhu zvakasungirirwa padanda, iro rakasungirirwa kune furemu rail screw uye rinogona kubviswa chero nguva. Rudzi urwu rwepurasitiki bumper inoshandisa purasitiki, inonyanya kushandisa polyester akatevedzana uye polypropylene akatevedzana ezvigadzirwa zviviri, uchishandisa nzira yekuumba jekiseni. Kune dzimwe nyika kunewo rudzi rwepurasitiki inonzi polycarbon ester, kupindira mukugadzirwa kwealloy, alloy injection molding method, kugadzirisa kunze kwebumper kwete chete kune simba rakakwirira, asiwo kune zvakanakira welding, uye kushanda kwekuputira kwakanaka, kuwanda kwekuwedzera uye kuwedzera mumotokari. Plastic bumper ine simba, rigidity uye kushongedzwa, kubva pakachengeteka pakuona, kudhumhana kwemotokari kunogona kuita basa rekuchengetedza, kuchengetedza kumberi uye kumashure kwemota yemuviri, kubva pakuonekwa, inogona kuve yakabatana nemuviri muchidimbu, yakabatanidzwa mune yakazara, ine kushongedzwa kwakanaka, inova chikamu chakakosha chekushongedza chitarisiko chemotokari.
