A high-speed train connecting sleeper beam comprises an anti-S-shaped damper base and an anti-lateral-twisting pull rod base. Square pins and round pin positioning guiding installing holes, all of which are connected with a train body are formed in end side beams. The high-speed train connecting sleeper beam is characterized in that the connecting sleeper beam is of an integral casting box structure, an integral cavity is formed in the middle of the connecting sleeper beam and serves as an additional air chamber for air springs, strengthening ribs are arranged on the upper plane, and the inner cavity of the connecting sleeper beam is composed of transverse casting bars and longitudinal casting bars. According to the connecting sleeper beam, the strength of the connecting sleeper beam is guaranteed, manufacturability and air tightness are good, the weight is low, and the strength is high. The simplicity of mounting and dismounting of a bogie and the train body is achieved, the monopoly from the foreign technology is broken, and cost is reduced.
