The invention discloses an integrated framework and a bogie. The integrated framework comprises two side plates and a beam connected with the two side plates. The side plates and the beam are of a single-layer platy integrated structure and all made of carbon fiber composites. Primary spring installation bases are arranged at the two ends of each side plate, and a secondary spring installation base is arranged in the middle of each side plate. A swing bolster is arranged above the secondary spring instillation bases. A journal box pull rod base, transverse stop bases, a motor installation base, a gear case hanging base and a brake base are arranged on the swing bolster. The bogie comprises the framework. A steel structure is replaced with the carbon fiber composite framework, and by means of a hanging motor, a gear case and a brake device which are arranged in a body-suspended mode, the weight of springs and the weight of the bogie can be effectively reduced, and the fatigue resistance and the riding comfort are improved.
