Title:

FRAME AND FREIGHT TRAIN

Document Type and Number:

WIPO Patent Application WO/2021/036739

Kind Code:

A1

Abstract:

Disclosed are a frame and a freight train. The frame comprises a first longitudinal beam (10), a second longitudinal beam (20), a first traction beam (30), and a second traction beam (40), wherein the direction of extension of the first longitudinal beam (10) and the direction of extension of the second longitudinal beam (20) are both parallel to the running direction of the train, and the first longitudinal beam (10) and the second longitudinal beam (20) are arranged at an interval in a direction parallel to the horizontal plane; and a front end of the first longitudinal beam (10) and a front end of the second longitudinal beam (20) are connected via the first traction beam (30), and a rear end of the first longitudinal beam (10) and a rear end of the second longitudinal beam (20) are connected via the second traction beam (40). By means of the above arrangement, when the train runs, a bogie drives the first traction beam (30) and the second traction beam (40) to advance in the direction of extension of a rail, and the first longitudinal beam (10) and the second longitudinal beam (20) run along with the train. Due to the fact that the direction of extension of the first longitudinal beam (10) and the direction of extension the second longitudinal beam (20) are both parallel to the running direction of the train, compared with the situation where a boundary beam is arranged on a center sill and the direction of extension of the boundary beam is perpendicular to the running direction of the train, the resistance between the first longitudinal beam (10) and the air and the resistance between the second longitudinal beam (20) and the air are small, and the air resistance during running of the train is reduced.
