The invention discloses a wheelchair convenient for stair climbing and suburban cross-country and belongs to the technical field of the wheelchair. The wheelchair mainly consists of wheels, sway stands, a converter, a race frame, a suspension bracket, a seat and the like. The four-wheel wheelchair, provided by the invention, of which the front-to-rear wheel base at one side is big and the front-to-rear wheel base at other side is small is more superior to a wheelchair of which the wheel bases at two sides are equal in stair climbing and suburban cross-country; front-to-rear vertical jolt during stair climbing is avoided by the wheelchair; moreover, when each single wheel rises, the rise of one side of the wheelchair is only 1 / 2 of the rise of the single wheel; when two front wheels rise, each load-bearing single wheel is less than 1 / 4 of the overall mass, and load borne by two rear wheels is slightly greater than 1 / 4 of the overall mass; the wheelchair with such a structure cannot jolt during stair climbing, and only can slightly fluctuate from left to right; as the wheels climb stairs, the wheelchair is light, rapid and labor-saving.
