Abstract

A vehicle for ascending and descending stairs includes includes at least one power driven axle rotatably mounted on opposite sides of a lower elongate cross member of a frame assembly, at least one non-power driven axle rotatably mounted on one end of the pair of lower elongate side members of the frame assembly, at least one spider (152, 153) having an inner plate (152) and a parallel outer plate (153). The at least one spider is rotatably mounted on the at least one power driven axle and on the at least one non-power driven axle. The spider is further disposed of to form at least four radial arms, and a plurality of ground engaging wheels (182, 189) rotatably mounted at an edge of each radial arm of said at least four radial arms, and a motor, and a differential or epicyclic gearing mechanism having an input pinion shaft being powered by the motor.
