The invention discloses an axle box suspension device, a bogie and a railway wagon. The axle box suspension device comprises an axle box, guide frames and springs, wherein the guide frames are located on two sides of the axle box, the axle box is provided with spring bearing parts, and the springs are located between the guide frames and the spring bearing parts; two swing blocks and a spring damping gear are arranged between at least one guide frame and the spring; the two swing blocks are distributed side by side at intervals in the direction parallel to the axis of the axle box, an upper end of each swing block is matched with the guide frame in a rotatable mode, a lower end of each swing block is matched with the spring damping gear in a rotatable mode, and the swing blocks are obliquely arranged; an included angle is formed between the shaft box and the vertical direction, and a lower end deviates to the axle box; and a first friction surface of the spring damping gear and a second friction surface of the axle box form a friction pair capable of moving relatively. The device can improve dynamic performance of the vehicle and ensure that the dynamic performance of the vehicle is continuous and stable.
