Iyo bumper chishandiso chekuchengetedza chinotora uye kuderedza kukanganiswa kwekunze uye inodzivirira kumberi nekumashure kwemuviri wemotokari. Makore makumi maviri apfuura, mabhampa epamberi uye kumashure emotokari ainyanya kugadzirwa nesimbi. Iwo akadhindwa muU-shaped chiteshi simbi ine ukobvu hunodarika 3 mm, uye pamusoro pacho chaibatwa nechromium. Aive akarukwa kana kuti kubatanidza nedanda rehurefu refuremu, uye pakanga paine mukaha mukuru nemuviri, sokunge chikamu chakabatanidzwa. 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: yekunze ndiro, cushioning zvinhu uye danda. Iyo yekunze ndiro uye buffer zvinhu zvakagadzirwa nepurasitiki, uye danda rakagadzirwa nechando-yakakungurutswa shizha rine ukobvu hunosvika 1.5 mm uye rakaumbwa kuita U-shaped groove; Iyo yekunze ndiro uye cushioning zvinhu zvakasungirirwa kune danda, iro rakasungirirwa kune furemu njanji screws uye rinogona kubviswa chero nguva. Iyi bumper yepurasitiki inoshandisa purasitiki, kunyanya kushandisa marudzi maviri emidziyo, polyester uye polypropylene, uchishandisa jekiseni rekuumba nzira. Kune zvakare mhando yepurasitiki inonzi polycarbon ester series kune dzimwe nyika, kupinza mukati me alloy composition, alloy injection molding method, kugadzirisa kunze kwebumper kwete chete ine simba rakasimba, asiwo ine mukana we welding, uye kushanda kwekuvhara kwakanaka, kuwanda kwekuwedzera uye kuwanda mumotokari. Plastic bumper ine simba, rigidity uye kushongedzwa, kubva pakachengeteka pakuona, tsaona yekudhumhana kwemotokari inogona kuita basa rekuvhara, kudzivirira kumberi nekumashure kwemota yemuviri, kubva pakuonekwa kwemaonero, inogona kuve yakasanganiswa nemuviri muchidimbu, yakazara, ine kushongedzwa kwakanaka, inova chikamu chakakosha chekushongedza chitarisiko chemotokari.
