Railway vehicle end wall assembly and through channel design method

Abstract

The invention discloses a railway vehicle end wall assembly and a through channel design method. The end wall assembly comprises an end wall and a drainage pipe, the end wall comprises an end wall top plate and two end wall side plates which are connected to the lower portion of the end wall top plate and arranged left and right in a spaced mode, and the end wall top plate and the end wall side plates are both of a profile structure. One or more cavities of the end wall top plate and the end wall side plate are connected with a through channel, the cavity wall thickness of the cavities, connected with the through channel, of the end wall top plate and the end wall side plate is larger than the cavity wall thickness of the other cavities of the end wall top plate and the end wall side plate; the end wall is provided with an inner concave part, so that the drainage pipe can reserve a larger installation space for the through channel. By means of the scheme, the end wall is light in weight, the running resistance of the whole vehicle is small, the through channel is not prone to abrasion, the width of the vestibule shed of the through channel can be widened, the end wall meets the installation requirements of different types of through channels, and unification and interchange of the different types of through channels can be achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a composition of an end wall of a rail vehicle and a design method for a through passage. Background technique [0002] The end wall of the rail vehicle provides the installation interface for the through channel, and the types of the through channel are various, and the positions of the holes of different types of the through channel are various. [0003] At present, due to the influence of the diversification of the end wall structure and the position of the through channel connection hole, one type of end wall cannot meet the installation requirements of various types of through channels, and the parts of different types of through channels cannot be interchanged, that is, It is said that one type of end wall can usually only be installed with one fixed type of through channel, but other types of through channels cannot be installed interchangeably, resulting in the need...

[0003] At present, due to the influence of the diversification of the end wall structure and the position of the through channel connection hole, one type of end wall cannot meet the installation requirements of various types of through channels, and the parts of different types of through channels cannot be interchanged, that is, That is to say, one type of end wall can usually only be installed with one fixed type of through-channel, but other types of through-channels cannot be installed interchangeably, resulting in the need for operating companies to stock a large number of spare parts for emergencies
