Abstract
An anti-rollover motorized vehicle includes a chassis, a front wheel and a rear two wheels assembly including a tilting base and a four-bar linkage structure. The tilting base is connected to the chassis through a supporting structure. The four-bar linkage structure suitable for connecting the chassis with two rear wheels includes first, second, third and fourth linkages. The first and second linkages are pivoted to the tilting base. The third and fourth linkages pivoted to two ends of the first and second linkages respectively are connected to the supporting brackets of the two rear wheels respectively. When the chassis is tilted, the tilting base and the supporting structure are also tilted, the first and second linkages are maintained at a constant angle relative to a road surface, and the third and fourth linkages are also tilted, such that track width of the two tilting rear wheels is maintained.
