The invention discloses a bogie wheel set radial mechanism with an adjustable rigidity structure. The mechanism is formed by pin joint of two crossed connecting rods through a front auxiliary framework and a rear auxiliary framework. The connecting rods are in pin joint with the auxiliary frameworks through circular pins, and the joint parts of the circular pins and the connecting rods or/and theauxiliary frameworks are provided with replaceable elastic materials; the joint parts of the cylindrical pins and the connecting rods or/and the auxiliary frameworks are provided with rings made of the replaceable elastic materials; the ends of the connecting rods are embedded into installing grooves of the auxiliary frameworks and are in pin joint through the cylindrical pins; the ends of the connecting rods are located on an upper installation plane or a lower installation plane of the auxiliary frameworks and are in pin joint through cylindrical pins. By arranging the replaceable elastic materials with the bufferin
