Embodiment Construction

[0032] In the following description, the term "longitudinal" is defined with respect to the direction of travel of the rail vehicle to which the bogie belongs, ie the direction of travel of the track on which the vehicle travels.

[0033] The term "transverse" is defined with respect to a direction substantially perpendicular to the longitudinal direction, ie the direction in which the guide rails are spaced apart from each other.

[0034] figure 1 A chassis 1 of a bogie for a rail vehicle is shown in .

[0035] The chassis 1 comprises two longitudinal beams 3 extending longitudinally between the first end 5 and the second end 7 and two transverse beams 9A extending transversely and connecting the two longitudinal beams 3 connected to each other.

[0036] Alternatively, the chassis 1 may comprise more than two longitudinal beams 3 and / or more or fewer cross beams 9A.

[0037] Each stringer 3 comprises two side parts 11 , an upper part 13 and a lower part 15 . The upper par...

Abstract

The invention relates to a railway vehicle bogie comprising a chassis (1). The chassis (1) comprises: at least two longitudinal beams (3) extending in a longitudinal direction between a first end (5)and a second end (7); and at least one transverse beam (9A,9B) extending in a transverse direction substantially perpendicular to the longitudinal direction and connecting the two longitudinal members(3) to one another. The chassis comprises at least two holding members (17A, 17B) welded respectively to the first end (5) of each of the longitudinal members (3) and the transverse beam (9A, 9B) isbolted to each of the holding members (17A, 17B) .

Description

technical field [0001] The invention relates to a rail vehicle bogie of the type comprising: [0002] - at least two stringers extending longitudinally between the first end and the second end; [0003] - At least one transverse beam extending in a transverse direction substantially perpendicular to the longitudinal direction and connecting two longitudinal beams to one another. Background technique [0004] In order to construct bogies of this type, it is known to fix the various elements making up the chassis by welding, for example by welding the ends of the transverse beams to the ends of the longitudinal beams so that the parts are integral with each other. [0005] The structure of this type of bogie, and in particular the limited accessibility of certain areas of the chassis, requires manual or semi-automatic welding of the components. This has the effect of making the chassis complex and time-consuming to manufacture. [0006] Additionally, the quality of welds ma...
