The utility model provides a secondary suspension device for a rapid truck bogie, and relates to a railway cargo transportation device, particularly to a bogie for a rapid truck. The secondary suspension device comprises swing bolsters and a framework. The secondary suspension device has the key technology that rollers are mounted on the framework via rotating shafts, the swing bolsters which are horizontally placed on the rollers are vertically connected with the framework, and the swing bolsters are transversely connected with the framework via transverse springs. The secondary suspension device has the benefits that on one hand the secondary suspension device can adjust the transverse rigidity of the whole bogie according to the rigidity of the transverse springs, so as to ensure the stationarity of the whole bogie in rapid or high-speed operation; on the other hand, empty and loaded secondary no deflection differential of the bogie is achieved, and the effect of an air spring equipped on a similar railway
