Tsamba ndi chophimba (chidutswa chokwera pang'ono, chozungulira pang'ono pamwamba pa gudumu) pamagalimoto oyendetsa galimoto ndi omwe si a injini, monga momwe dzinalo likusonyezera, chimakwirira chipolopolo chakunja cha magalimoto oyendetsa galimoto ndi omwe si a galimoto.Mogwirizana ndi mphamvu zamadzimadzi, chepetsani mphamvu yolimbana ndi mphepo, mulole galimoto iyende bwino.
Bolodi lamasamba limatchedwanso fender (lotchedwanso mawonekedwe ndi malo a gawo ili la thupi lakale la galimoto lomwe limafanana ndi mapiko a mbalame).Masamba a masamba amakhala kunja kwa thupi la gudumu.Ntchitoyi ndikuchepetsa mphamvu yolimbana ndi mphepo molingana ndi mphamvu yamadzimadzi, kuti galimotoyo ikuyenda bwino.Malinga ndi malo oyika, imatha kugawidwa m'mbale yakutsogolo ndi mbale yakumbuyo.Mbali yakutsogolo ya tsamba imayikidwa pamwamba pa gudumu lakutsogolo.Chifukwa gudumu lakutsogolo limakhala ndi chiwongolero, liyenera kuwonetsetsa kuti pali malire ambiri pomwe gudumu lakutsogolo likuzungulira.Tsamba lakumbuyo silimagundana ndi magudumu, koma pazifukwa zakuthambo, tsamba lakumbuyo limakhala ndi arc yopindika pang'ono yotulukira kunja.
Kachiwiri, bolodi lakutsogolo limatha kupanga njira yoyendetsera galimoto, kuteteza gudumu lokulungidwa mchenga, kuphulika kwamatope pansi pagalimoto, kuchepetsa kuwonongeka kwa galimotoyo ndi dzimbiri.Chifukwa chake, zida zomwe zimagwiritsidwa ntchito zimafunikira kuti zikhale ndi kukana kwanyengo komanso kukhazikika bwino pakuwumba.Chotchinga chakutsogolo cha magalimoto ambiri chimapangidwa ndi zinthu zapulasitiki zokhazikika, kotero kuti zimakhala ndi zopinga zina komanso zotetezeka.
