Chassis yimodoka igizwe na sisitemu yo kohereza, sisitemu yo gutwara, sisitemu yo kuyobora na sisitemu yo gufata feri. Chassis ikoreshwa mugushigikira no gushiraho moteri yimodoka nibiyigize hamwe ninteko, gukora imiterere rusange yimodoka, kandi yakira imbaraga za moteri kugirango ibinyabiziga bigende kandi byemeze gutwara bisanzwe.
Sisitemu yo kohereza: imbaraga zitangwa na moteri yimodoka zoherezwa kumuziga utwara na sisitemu yohereza. Sisitemu yo kohereza ifite imirimo yo kwihuta, guhindura umuvuduko, gusubira inyuma, guhagarika ingufu, gutandukanya uruziga no gutandukanya intera. Ikorana na moteri kugirango igenzure ibinyabiziga bisanzwe mubikorwa bitandukanye, kandi ifite imbaraga nubukungu.
Sisitemu yo gutwara:
.
2. Kwihanganira uburemere bwikinyabiziga n'imbaraga zo hasi;
3. Kugabanya ingaruka zatewe numuhanda utaringaniye kumubiri wikinyabiziga, komeza kunyeganyega mugihe utwaye ibinyabiziga no gukomeza kugenda neza;
4. Gufatanya na sisitemu yo kuyobora kugirango ibinyabiziga bikore neza;
Sisitemu yo kuyobora:
Urukurikirane rwibikoresho bikoreshwa muguhindura cyangwa kubungabunga ibinyabiziga cyangwa icyerekezo cyikinyabiziga cyitwa sisitemu yo kuyobora ibinyabiziga. Imikorere ya sisitemu yo kuyobora ibinyabiziga nugucunga icyerekezo cyikinyabiziga ukurikije ibyifuzo byumushoferi. Sisitemu yo kuyobora ibinyabiziga ningirakamaro cyane kumutekano wo gutwara ibinyabiziga, bityo ibice bya sisitemu yo kuyobora ibinyabiziga byitwa ibice byumutekano.
Sisitemu yo gufata feri: itume imodoka itwara gahoro cyangwa ihagarare ku gahato ukurikije ibyo umushoferi asabwa; Kora parikingi ihagaze neza mubihe bitandukanye byumuhanda (harimo no kumurongo); Komeza umuvuduko wimodoka zigenda zimanuka zihamye.
