Abstract

The invention relates to a rail vehicle end sleeper outside structure. The rail vehicle end sleeper outside structure comprises a vehicle hook mounting seat, a sleeper beam, traction beams, supporting plates and an aluminum floor. The aluminum floor is arranged on one side of the vehicle hook mounting seat, the two sides of the aluminum floor are connected with underframe side beams, and the underframe side beams are connected with the vehicle hook mounting seat. The sleeper beam and the multiple traction beams are arranged on the aluminum floor. One end of each traction beam is connected with the sleeper beam, and the other end of each traction beam is connected with the vehicle hook mounting seat through a traction beam transition plate. The two ends of each traction beam transition plate are connected with the corresponding underframe side beams through the corresponding supporting plates. One side of each supporting plate is connected with the vehicle hook mounting seat. By means of the rail vehicle end sleeper outside structure, the force transfer area of longitudinal force is increased, and single-direction transfer of the longitudinal force is dispersed.

Description

technical field [0001] The invention relates to an outer pillow structure at the end of a rail vehicle, and belongs to the technical field of vehicle body structure design. Background technique [0002] With the development of rail vehicles, higher design requirements and application requirements are put forward for the longitudinal bearing capacity of the car body. The existing outer end structure of the pillow generally adopts the welding of the traction beam and the corbel, and the longitudinal force of the car body is transmitted from the traction beam to the corbel, and then transmitted to the side beams on both sides by the corbel. When the car body is subject to a greater longitudinal force, this scheme cannot meet the high strength requirements of the car body. Affected by the axle load and lightweight requirements of the vehicle, it is impossible to increase the longitudinal load of the vehicle body by greatly increasing the material and weight of the vehicle body....
