Chimango cha kutsogolo kwa galimoto chimatanthauza chithandizo chokhazikika cha chipolopolo cha galimoto, ndipo chimango cha kutsogolo kwa galimotoyo ndi choteteza kugundana. Ndi chipangizo chomwe chimagwiritsidwa ntchito kuchepetsa kuyamwa kwa mphamvu ya kugundana galimoto ikagundana, ndipo chimateteza kwambiri galimotoyo.
Bulamba lakutsogolo limapangidwa ndi mtanda waukulu, bokosi lonyamula mphamvu, ndi mbale yolumikizira yolumikizidwa ndi galimoto. Mtanda waukulu ndi bokosi lonyamula mphamvu zimatha kuyamwa mphamvu yogundana bwino ngati galimoto yagundana mofulumira kwambiri ndikuchepetsa kuwonongeka kwa mtanda wautali wa thupi chifukwa cha mphamvu yogundana. Chifukwa chake, galimotoyo iyenera kukhala ndi bulamba kuti iteteze galimotoyo komanso kuteteza chitetezo cha anthu omwe ali mgalimotoyo.
Anzanu omwe amadziwa bwino magalimoto amadziwa kuti chipolopolo cha bumper ndi bumper ndi zinthu ziwiri zosiyana. Zimawoneka zosiyana ndipo zimagwira ntchito mosiyana kutengera mtundu wa galimoto. Chipolopolocho chimayikidwa pachipolopolocho, ziwirizi si chinthu chimodzi, koma zinthu ziwiri.
Chigoba cha bumper ndi chida chofunikira kwambiri chotetezera galimoto. Chigoba cha bumper chimagawidwa m'magulu awiri: bumper yakutsogolo, bumper yapakati ndi bumper yakumbuyo. Chigoba chakutsogolo chimaphatikizapo mzere wa bumper wakutsogolo, bulaketi yakumanja ya chimango chakutsogolo, bulaketi yakumanzere ya chimango chakutsogolo, ndi chimango chakutsogolo. Zonsezi zimagwiritsidwa ntchito kuthandizira kusonkhana kwa bumper yakutsogolo.
