The invention discloses a railway vehicle wheel set radial device and a bogie thereof. The wheel set radial device is formed by connecting a front auxiliary framework, a rear auxiliary framework and two connecting rods which are arranged in a crossed mode through round pins in a pin joint mode, the auxiliary frameworks are of U-shaped structures, and the middle portions of transverse arms of the auxiliary frameworks sink to form concave face structures. The auxiliary framework transverse arm is provided with a connecting rod mounting surface for mounting a connecting rod; the end parts of the connecting rods are positioned on the mounting surfaces of the connecting rods and are in pin joint through round pins; the bogie comprises a wheel pair, a bearing, a swing bolster assembly, a side frame assembly, a foundation brake device and a wheel pair radial device, the wheel pair radial device is adopted, the connecting rod and the foundation brake device both penetrate through a swing bolster assembly hole, the connecting rod is located on the lower side of the foundation brake device, and the depth of a center pin of the bogie inserted into the swing bolster assembly is larger than or equal to 160 mm. The advantages of good operation stability, excellent curve passing performance and the like are guaranteed, the requirement that the bogie can adapt to assembly of different basic brake devices is met, and the adaptability and universality of the bogie are improved.
