A variable section side wall of a railway freight car

Abstract

The invention relates to a variable cross-section side wall for a freight wagon. The variable cross-section side wall is characterized by comprising a side wall framework, a plurality of side door posts, a plurality of side posts, a plurality of first side wallboards and a plurality of second side wallboards, wherein the side wall framework comprises two end posts, and an upper side beam and a lower side beam which are fixed together with the two end posts; corresponding to one side of the installation position of a sliding door and the moving position of the sliding door, a segment of upper auxiliary beam is welded on the bottom surface of the upper side beam; a segment of lower auxiliary beam is welded on the top surface of the lower side beam; the inner surfaces of the upper and lower auxiliary beams are flush with inner surfaces of the upper side beam and the lower side beam; the side door posts are fixed between the upper auxiliary beam and the lower auxiliary beam at intervals; the side posts are fixed between the upper side beam and the lower side beam at intervals; the first side wallboards are fixed on the outer sides of the side door posts; the second side boards are fixed on the outer side of the side posts. According to the variable cross-section side wall, the first side wallboards are fixed on the outer sides of the side door posts, and the second side boards are fixed on the outer side of the rest of side posts, so that an inward indent is formed in a side door relatively to the first side wallboards and the second side wallboards which are positioned at one side of the side door, the sliding door can slide freely in the indent, and the width of a vehicle body is not influenced.

Description

technical field [0001] The invention relates to a side wall of a railway freight car, in particular to a variable-section side wall of a railway freight car. Background technique [0002] When the railway freight car moves in a curve, the vehicle will produce an offset, and the offset of the vehicle is related to the geometric dimensions of the vehicle itself, such as the length, width and fixed distance of the vehicle. Therefore, when the size of the vehicle is too large, the width of the vehicle must be reduced to ensure the space required for safe driving. Existing railway wagons are equipped with side doors (such as boxcars) outside the side walls for the purpose of loading, but the side doors occupy the width of the vehicle. When the size of the vehicle is too large, the maximum manufacturing width of the vehicle will be reduced, which will result in a large space inside the vehicle. Reduced, affecting the volume of the vehicle. In order to solve the above problems, a...

Existing railway wagons are equipped with side doors (such as boxcars) outside the side walls for the purpose of loading, but the side doors occupy the width of the vehicle. When the size of the vehicle is too large, the maximum manufacturing width of the vehicle will be reduced, which will cause the interior space of the vehicle to increase. Reduced, affecting the volume of the vehicle
