The invention discloses a radial bogie for actively controlling a wheel pair to swing around the center of the radial bogie, and relates to the technical field of rail transit, machinery and control. Comprising a car type structure, a wheel set device, a rocker arm steering device, a center swing bolster device and an electric control driving device. The wheel pair devices are arranged on the front side and the rear side of the car-shaped structure and connected with the rocker arm steering devices through pin shafts, the rocker arm steering devices are symmetrically distributed on the two sides of the center swing bolster device and connected with the center swing bolster device, the center swing bolster device is connected with the center position of the car-shaped structure through a pin shaft, and the electric control driving device is connected with the car-shaped structure through a hinge. According to the radial bogie capable of actively controlling the wheel pair to swing around the center of the radial bogie, in order to enable a train to achieve the radial steering function, the kinematics principle of a multi-rod mechanism is adopted, the rail train can have better stability and safety in steering, and wheel track abrasion and noise are reduced.
