Star-shaped wheeled motor vehicle for stairs

Abstract

The invention relates to a motor vehicle, such as a wheelchair, comprising a main chassis (14), first ground connections fixed to the main chassis, second ground connections longitudinally at a distance from the first, and an articulation device (20) for the second ground connections relative to the main chassis. The articulation device comprises a bent body (34), a first longitudinal pivot connection (36) connecting the bent body to the main chassis, and a second vertical pivot connection (38) connecting the bent body to the second ground connections. The ground connections each comprise a hub (22) with a central axis of rotation (24), three wheels (26). The bent body comprises a concave surface (48) facing the second ground connections (18). Relative to the central axis of rotation of the hub of the second ground connections, the concave surface is radially at a distance from the associated wheels.
