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 a rail vehicle end sleeper outer structure, which belongs to the technical field of vehicle body structure design. Background technique [0002] With the development of rail vehicles, higher design and use requirements have been put forward for the longitudinal load-bearing capacity of the car body. The existing bolster outer end structure generally adopts traction beam and bolster beam welding, and the longitudinal force of the car body is transmitted from the traction beam to the bolster, and then from the bolster to the side beams on both sides. When the car body is subjected to greater longitudinal forces, this solution cannot meet the high strength requirements of the car body. Affected by the vehicle axle load and lightweight requirements, it is impossible to increase the vehicle body's longitudinal load by greatly increasing the body material and weight. If a large number of reinforcement plates are added to the weak parts ...
