(1) Igihagararo kitari-cigenga: Mu gihagararo kitari-cigenga, amapine ashirwa ku mpera zompi z’umurongo umwe. Iyo uruziga rumwe rugurutse, ruragira ico rukoze ku rundi, bigatuma imodoka yose inyiganyiga canke igahengamira. Imodoka zifise iyo nzira yo guhagarika muri rusangi ntizishobora guhagarara neza kandi ntizigira umunezero mwinshi, ariko kubera ko zikora neza kandi zishobora kwikorera umuzigo mwinshi, akenshi zikoreshwa mu bikamyo bikomeye-, mu bisi, no mu bindi binyabiziga bimwebimwe bidasanzwe.
(2) Igihagararo cigenga: Mu guhagarara kwigenga, umugozi ugabanywamwo ibice bibiri, kandi uruziga rumwe rumwe rushirwa munsi y’igiti hakoreshejwe umupfunda w’uruziga. Iyo uruziga rumwe rugurutse, urundi ruziga ntirugira ico rukoze, ivyo bikaba bigabanya cane ukunyiganyiga kw’imodoka kandi bikaba bituma umuntu agira umunezero mwinshi canecane iyo ariko ariruka cane, aho na vyo nyene bituma umuntu ahagarara neza. Ariko rero, ubwo bwoko bw’uguhagarika buragoye cane, burafise ubushobozi bwo kwikorera umuzigo muto-, kandi buragora uburyo bwo gutwara n’uguyobora imodoka. Imodoka nyinshi zitwara abantu zikoresha ivyuma vyigenga imbere n’inyuma, kandi ivyo vyacitse ikintu gikomeje gutera imbere. Ivyumba vy'uguhagarika vyigenga birimwo ubwoko butandukanye nk'ubwoko bw'ubuji, ubwoko bw'ivyuma vya MacPherson, n'ubwoko bw'amahuza menshi-. Ubwoko bw’ubuji n’ubwoko bw’ivyuma vya MacPherson birasa mu buryo, vyose bifatanya umupfunda w’ivyuma n’ivyuma bifata umuriro, ariko biratandukanye cane kubera ubudasa bw’imiterere yavyo. Ubwoko bw’ubuji bukoresha ikintu gihagaze aho uruziga rugenda rujanye n’umurongo w’umwami, ni co gituma ryitwa (risa n’ubuji). Ikiranga ni uko ikibanza c’umwami n’imfuruka z’ugutunganya uruziga rw’imbere bidahinduka iyo uruziga rugenda ruhagaze, ivyo bikaba ari ngirakamaro ku bijanye no gukoresha neza imodoka no guhagarara neza. Ubwoko bw’igikoresho ca MacPherson ni igikoresho gihagaze gifise igikoresho co gukingira gifise amahembe n’ukuboko kwo hasi gucungera. Ico gikoresho co gukingira umuyaga gishobora kandi gukora nk’igikoresho co gutwara umuduga, kikaba ari co gipfukisho c’umuduga gishobora gukikuza. Ikiranga ni uko ikibanza c’umwami n’imfuruka z’uruziga rw’imbere bihinduka uko uruziga rugenda ruhagaze, bikaba bihushanye n’uguhagarara kw’ubwoko bw’ubuji. Ico gikoresho gifise ubuhinga bworoshe, giteye neza, kandi nta mpinduka nyinshi zigira mu bijanye n’ugutunganya amapine y’imbere, ivyo bikaba bituma umuntu ashobora gutwara neza. Ku bw’ivyo, igihimba c’umubiri citwa MacPherson strut suspension ni co gikoreshwa cane mu modoka zitwara abantu.
