The invention discloses a connecting structure of a railway vehicle body and a bogie. The connecting structure comprises a traction pin fixedly connected with the vehicle body. The bogie comprises a swing bolster and a core plate, the swing bolster is provided with a stepped through hole, the stepped through hole comprises a small-diameter hole located on the lower portion and a large-diameter hole located on the upper portion, and the connection position of the small-diameter hole and the large-diameter hole forms an upward stepped surface; the core plate is located in the large-diameter hole, and the step surface is used for supporting the core plate; the core plate is provided with a central hole communicated with the step through hole; and the traction pin penetrates through the central hole to be matched with the small-diameter hole. The connecting structure can meet the installation requirements of compact structure and narrow space of the railway vehicle.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a connection structure between a rail vehicle body and a bogie. Background technique [0002] At present, for the bogie of a rail vehicle, a core plate is arranged in the center of the bolster, and a center pin hole passing through the bolster is arranged in the center of the core plate, and the bogie is connected to the car body through the center pin and fasteners. [0003] In the case of a vehicle with a compact structure and a small space, the above-mentioned connection method between the bogie and the car body cannot meet the requirements. In view of this, how to improve the connection structure between the car body and the bogie to meet the installation requirements of the vehicle with a compact structure and a small space Requirements are technical problems that those skilled in the art need to solve. Contents of the invention [0004] The object of the present in...
