The invention discloses a stair climbing vehicle which comprises a stair climbing mechanism. The stair climbing mechanism comprises a transmission main shaft and a differential mechanism. The differential mechanism comprises an inner side three-supporting-arm star-shaped support, an outer side three-supporting-arm star-shaped support and a three-way support. The inner side three-supporting-arm star-shaped support is connected to the transmission main shaft, a center bevel gear is fixed to the center of the inner side three-supporting-arm star-shaped support, the three-way support is correspondingly fixed to the transmission main shaft, the inner end of the three-way support is rotationally connected with the center bevel gear, the upper end and the lower end of the three-way support are each connected with a planetary bevel gear, and the two planetary bevel gears are meshed with the center bevel gear and an outer side bevel gear. A chain wheel shaft is fixed to the outer end of the outer side bevel gear. The middles of the ends of three pairs of supporting arms of the inner side three-supporting-arm star-shaped support and the outer side three-supporting-arm star-shaped support of the chain wheel shaft are all provided with a chain wheel, the chain wheels are connected with the chain wheel shaft, axles are fixed to the chain wheels, and the axles are connected with climbing wheels through one-way bearings. The stair climbing vehicle is stable in stair climbing, safe, reliable and capable of greatly saving labor.
