Problems solved by technology
[0004] Due to the heavy weight of the coupler mounting seat of the carbon steel structure, the structure after the connection of the traction beam and the coupler mounting seat is heavy, which cannot meet the lightweight requirements of the car body
[0005] More importantly, the two webs of the traction beam are only connected by the coupler mounting seat in the transverse direction, and are open in the up and down direction. When subjected to excessive compressive loads, the two webs will be turned outward. Even large deformation occurs locally, which increases the local stress of the traction beam and affects the bearing capacity of the traction beam

Embodiment Construction
[0025] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can accurately understand the technical solution of the present invention.
[0026] The up and down, left and right, and front and rear mentioned in this article refer to the driving state of the rail vehicle, and the direction perpendicular to the track surface is the up and down direction. In the up and down direction, the direction pointing to the track surface is down, and the direction away from the track surface is up; In a plane parallel to the track surface, the direction of the running direction of the rail vehicle is the front, and the direction opposite to the front is the rear. In this plane, the direction perpendicular to the front and rear is the left and right direction, along the running direction of the rail vehicle. See, the direction on the left hand side is left, and the direction on the r...

The invention provides a traction beam of a rail vehicle. The lightweight requirement of a vehicle body can be met while the strength of the vehicle body is satisfied. The traction beam comprises an upper cover plate, lower cover plates, webs and a draw gear mounting seat, wherein the webs are connected between the upper cover plate and the lower cover plates, and the draw gear mounting seat is formed by aluminum profile extrusion. An interface is reserved in the bottom surface of the upper cover plate and three or more webs are transversely disposed on the bottom surface of the upper cover plate at intervals. The lower cover plates are closed between the adjacent webs in a covering mode, and the draw gear mounting seat locates at the front ends of the webs in a blocking mode after being engaged with the interface so as to be engaged with the front ends of the lower cover plates to form a box type beam.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to a traction beam of a rail vehicle. Background technique [0002] In the prior art, the traction beam includes two webs, a coupler mounting seat is connected between the two webs through rivets, and the coupler mounting seat is connected with the coupler, thereby realizing the transmission of traction force. In this structure, a carbon steel coupler mounting seat is used, which is welded with carbon steel plates, and then connected to the web of the traction beam by rivets. [0003] There are following problems in above-mentioned prior art: [0004] Because the coupler mounting seat of the carbon steel structure is relatively heavy, this makes the structure after the traction beam is connected with the coupler mounting seat heavy, which cannot meet the lightweight requirements of the car body. [0005] More importantly, the two webs of the traction beam are only conn...
