Provided is a transportation vehicle, comprising a chassis (10) and a wheelset structure (20). Each side of the chassis (10) is pivotally connected to at least one wheelset structure (20). The wheelset structure (20) comprises a connecting member (23) and two wheels (21, 22) pivotally arranged on the connecting member (23), the connecting member (23) having a pivot point used for pivotally connecting to the chassis (10), and the pivot point being located between the two wheels (21, 22). By changing the connection manner between the wheels and the chassis, when the vehicle is travelling on the uneven ground, the heights of the two wheels from the ground are automatically adjusted by gravity pressing down so as to facilitate the wheels contacting the ground.
