Magiya a nyongolotsi ndi mawilo ofunika ndi zinthu zofunika mu ma germ ma germ, omwe ndi mitundu ya ma gear syrems omwe amagwiritsidwa ntchito pakuchepetsa komanso kuchuluka kwa torque. Tiyeni tichepetse chinthu chilichonse:

1. Guar Gear: Guar Gigar, yemwenso amadziwikanso kuti mbozi, ndi zida za cylindrical yokhala ndi ulusi wozungulira wozungulira ndi mano a gudumu la nyongolotsi. Magiya a nyongolotsi amayendetsa gawo loyendetsa mu gearbox. Imafanana ndi chinsalu kapena nyongolotsi, chifukwa chake dzinali. Kutalika kwa ulusi pa nyongolotsi kumatsimikizira kuchuluka kwa zida za dongosolo.
2. Gudumu la nyongolotsi: gudumu la nyongolotsi, lotchedwanso guya la nyongololo kapena guwa la nyongololo, ndi zida zoweta zomwe zimaluntha ndi zida za nyongolosi. Imafanana ndi chizolowezi chachikhalidwe kapena zida zazikulu kwambiri koma ndi mano omwe amakonzedwa mu mawonekedwe a concove kuti afanane ndi mphutsi za nyongolotsi. Whatchi ya nyongolotsi nthawi zambiri imakhala chinthu choyendetsedwa mu gearbox. Mano ake adapangidwa kuti azichita bwino ndi zida za nyongolotsi, kufalitsa mayendedwe ndi mphamvu moyenera.
