Railway vehicle and end wall thereof

Abstract

The invention discloses a railway vehicle and an end wall thereof, wherein the end wall is used for being matched with a roof, an underframe and a side-pull vehicle door of a vehicle body, and comprises an end wall body and a buffer pad, wherein the inner end surface and the outer end surface of the framework of the end wall body are respectively coated with a skin, two side plate edges of the outer skin are respectively provided with bent sections, the bent sections are formed by extending outwards along the plate surface of the outer skin and then longitudinally extending inwards, and the bent sections and the corresponding side surfaces of the framework are encircled to form accommodating grooves for accommodating the side edges of the end parts of the side-pulling vehicle door; the buffer pad is arranged in the groove bottom of the accommodating groove so as to be matched with the side edge of the side-pulling vehicle door in an abutting mode. According to the scheme, through structural optimization, vibration of the vehicle door can be effectively reduced, and a good technical guarantee is provided for improving the running performance of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail vehicle and an end wall thereof. Background technique [0002] The current economic development mode is shifting from extensive growth of scale and speed to intensive growth of quality and efficiency, and the logistics market has undergone profound changes accordingly. Come blowout development. In order to meet the market demand and give full play to the advantages of railway transportation, the application prospect of express boxcar is good. [0003] The end wall of the existing vehicle model is limited by its own structure, and cannot effectively suppress the vibration of the matching side-drawing car door. In addition, most of the reinforced structures such as horizontal belts or columns are placed outside the end wall, and the degree of commercialization is low; moreover, the connection strength between the end wall and the roof is weak. [0004] In view...
