A core disc structure for connecting a locomotive and a steering frame is characterized by comprising oil openings, lubricant grooves, an upper core disc body, a nut, a stud shaft, lubricating gaps and a lower disc body, wherein the core disc structure is provided with the upper core disc body and the lower core disc body, the nut is arranged in the center of the upper core disc body, and the lubricating gaps are formed in the upper core disc body and the lower core disc body; the contact planes of the core disc bodies are planes so that wear can be lowered; the vertical stud shaft is arranged between the upper core disc body and the lower core disc body to connect the upper core disc body and the lower core disc body in series; the lower end of a bolt is welded to the lower core disc body in a sealed manner, and the upper end of the bolt is connected with the upper core disc body through the nut; stators of the stud shaft are fixedly welded to the core disc bodies, a rotor of the stud shaft is in transmission connection with the nut in the upper core disc body, and the lubricant grooves are formed in the two sides of the core disc structure and provided with the oil openings. The core disc structure for connecting the locomotive and the steering frame has the beneficial effects that transmission efficiency is high, no energy loss generated by friction exists, no hard impact among parts exists, the service life of the parts is long, lubricating oil is saved, no dust or noise is generated in the movement process, and bearing capacity is high.
