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. |

1. A gear system for attachment to a vehicle traveling in a forward direction over a surface, the gear system comprising:
a first axle system that is positioned to contact the surface toward a front side of the vehicle; a second axle system that is positioned to contact the surface toward a rear side of the vehicle; a third axle system that is positioned to not contact the surface; and a center axle, wherein, in a case where the vehicle encounters an obstruction, each of the first axle system, the second axle system, and the third axle system rotates in the forward direction around the center axle, wherein, after the rotation is complete, (i) the first axle system is positioned to contact the surface toward the rear side of the vehicle, (ii) the second axle system is positioned to not contact the surface, and (iii) the third axle system is positioned to contact the surface toward the front side of the vehicle, and wherein the vehicle continues to travel in the forward direction throughout the rotation of the first axle system, the second axle system, and the third axle system. |
