Abstract: A gear system to assist with transportation on uneven ground and stairs comprising three or more axle systems with outer gears that all mesh with inner gears so that the axle systems, which are supported at either end by a triangle bracket secured by bushings, turn in the same direction. When attached to a vehicle traveling on a flat surface, the gear system has one axle system in the air and two axle systems on the ground, forming a triangle. When the vehicle drives forward, if the axle system on the ground in the front encounters any unevenness, such as rocks or stairs, the entire gear system will rotate toward the front around the axle that is through the inner gear, as the vehicle continues to move forward throughout the rotation. This prevents any uneasy movements and allows the vehicle to fluidly traverse uneven ground or climb stairs.
