Abstract

The utility model relates to a roof side rail which is composed of a roof side rail body, and is characterized in that a roof side rail body is an integral forming continuous long unequal-sided angle-shaped member, wherein, one side forms an arc. The roof side rail increases the strength and the rigidity to reach the requirement of the international general technology standard and improves the technology level and grade of home-make railway carriages.

Description

The roof roof rail
Technical field:
The utility model relates to railway principal mode passenger car body light weight steel shape, especially relates to a kind of roof roof rail.
Background technology:
According to the authoritative motor train unit of international railway and passenger car body intensity, rigidity Design standard-required, steel structure of car body be except bearing along the vertical clamp load of 1500kN of coupler and draft gear longitudinal centerline effect, also must can bear vertical clamp load of 300kN in roof and side wall junction.And traditional roof roof rail is to splice assembly welding behind the segmentation die mould again to meet at right angles, and combine the back with the side top board gapped, influences intensity, thereby do not possess the ability that satisfies above-mentioned car body strength designing requirement.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of structural strength, roof roof rail that rigidity levels is high, to overcome the defective that background technology exists.
The technical solution of the utility model is: comprise roof roof rail body, roof roof rail body is the member of global formation and continuously elongated scalene dihedral, Yi Bian wherein be arc.
The utility model roof roof rail is the member of global formation and continuously elongated scalene dihedral, be arc on one side wherein, therefore, improved intensity, rigidity, reach the requirement of international technical standard, improved the technical merit and the grade of homemade passenger train.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises roof roof rail body 1, and roof roof rail body 1 is the member of global formation and continuously elongated scalene dihedral, 2 is arc on one side wherein.

Claims (1)

1, a kind of roof roof rail comprises roof roof rail body, it is characterized in that: roof roof rail body is the member of global formation and continuously elongated scalene dihedral, Yi Bian wherein be arc.
