The invention belongs to the field of railway vehicles and discloses a radial bogie. The radial bogie is composed of a main truss 100, an auxiliary truss 200 and a wheel set axle box 300. The auxiliary truss is provided with two right-angled n-shaped end frames. The two end frames are hinged through a hinged support in the middles of small beams of the end frames. The shoulder portions of the two end frames are provided with anti-hunting dampers 201. The two ends of each end frame are arranged on the wheel set axle box in a sleeving mode through axle box seats 204, the main truss 100 is of an H-shaped structure, two side beams of the main truss are located on the four axle box seats of the auxiliary truss and form hinged connection with two axle box seats in the diagonal relationship, and a short chain 120 is arranged in the center of the main truss to be connected with a suspension pin 210 on the auxiliary truss. The main truss and the auxiliary truss are perpendicularly restrained, while slight swing of the auxiliary truss is not limited. When a vehicle passes through a curve, the bogie tends to be at the radial position, and therefore the vehicle can smoothly pass through the curve. When the vehicle passes through a straight line, the bogie can rapidly return to the linear running state, and vehicle running stability is ensured.
