Core disc structure for connecting locomotive and steering frame

Abstract

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.

Description

technical field [0001] The invention relates to the field of core disc devices for motor vehicles, and in particular provides a core disc structure for connecting locomotives and bogies. Background technique [0002] The existing locomotive core plate only transmits longitudinal force and lateral force, and requires a relatively complicated contact side support structure to bear the gravity of the vehicle body. The traditional core plate transmits traction force by the side of the traction pin. This structure requires high strength of the pin and relatively low wear. For the harsh tunnel construction environment, there are many locomotive derailments, and the safety requirements for the core disc are high. The existing core disc device is prone to dust and noise during movement, and consumes a large amount of lubricating oil. Disk bearing force is lower, service life is shorter, often need to repair, expense cost is higher, and many other problems need to be solved urgently....

Problems solved by technology

[0002]The existing locomotive core plate only transmits longitudinal force and lateral force, and requires a relatively complicated contact side support structure to bear the gravity of the vehicle body. The traditional core plate relies on the side of the traction pin To transmit traction, this structure has high requirements on the strength of the pins and greater wear and tear. For the harsh tunnel construction environment, there are many locomotive derailments, and the safety requirements for the core disc are high. The existing core disc device is easy to Dust and noise are generated, and a large amount of lubricating oil is consumed, and the core disc has low bearing capacity, short service life, frequent maintenance, high cost, and many other problems that need to be solved urgently
