Abstract

Welded rotary stringer for rail vehicles with horizontally lying axle suspension. The solution according to the invention is intended make it possible that the mass of the longitudinal member reduces and the Manufacturing is made more economical. The invention is the technical problem underlying a rotary member to create, for the realization of an optimal upper frame suspension ira central region has a low-lying upper chord. Reached This is due to the fact that the box cross section from the curly Upper belt, a flat inner sheet and a bent?.? Outside sheet is formed while provided on both sides with a threaded hole Face plates and headers form the conclusion. That over the Upper flange raised inner and outer sheet is used for attachment the cradle stops. Further fields of application are not recognizable. - Fig, 1 ~

Title of the invention

Welded bogie rail carrier for rail vehicles

Field of application of the invention

The invention relates to a welded bogie beam for a low-lying bogie frame rail vehicles, in the higher-lying headers which are designed as an angle arm bearing axle housing are rotatably mounted and which is sprung against the axlebox each by a horizontal axis suspension.

Characteristic of the known technical solutions

There are already known welded bogie beam, in which the horizontal axis suspension is located below the bogie beam.

This solution has the disadvantage that an extremely low-lying side member, as it is necessary to realize a simple Flexicoilfederung between bogie frame and upper frame, is not realized and therefore a costly pendulum bearing had to be chosen here for the suspension suspension. In addition, the attachment of the axle suspension below the longitudinal member and the opening of the longitudinal member to accommodate the suspension suspension requires a multi-part and complex Längsträgepteonstruktioru

Furthermore bogie beams are known parts in the middle of three in the majority of very complicated mates exist, to the 'at would take of angle core and suspension massive Stahlgußkopf pieces complicated shape by butt joint are welded.

Although this solution allows the inclusion of axle suspension in the longitudinal member, but in this case the longitudinal member in the central region also still relatively high, so that the cross member connection can be done below the radii of radii. This concept requires numerous hip installations, still brings too high a height of the middle longitudinal beam area, is technologically very complex and results in a large longitudinal carrier mass.

Object of the invention

The solution according to the invention should allow the mass of the longitudinal member to be reduced and the production made more economical ·

Explanation of the essence of the invention

The object of the invention is to provide a bogie longitudinal member which has a low-lying upper flange for the realization of an optimal upper frame suspension in the central region.

Erfindimgsgemäß the object is achieved in that the box cross-section of the bogie stringer is formed from the known perched upper chord, a flat inner panel and a bent outer panel, inner and outer panels enclose the upper flange laterally and to attach the attacks for the cradle locally over the upper chord are pulled out lashing, while the bogie beam at the transition to the head ™

pieces in the lower part is completed by a respective end plate, and that the end plates are further attached laterally with their upper notches between inner and outer plate and their upper boundary surfaces are provided with known stop plates.

Preferably, the end plates are provided with a GewindebohruDg and their outwardly drawn contour hook-shaped

The invention will be explained in more detail using an exemplary embodiment.

embodiment

In the accompanying drawing show?

Pig · 1: a side view of the solution according to the invention in half section;

PIg ₆ 2: a section along the line AA of the Pig «1; Pig. 3: a side view according to Pig · 1.

In order to realize an optimal upper frame suspension, the illustrated bogie longitudinal member has a low-lying curved upper flange 1 in the middle region, which together with the flat inner panel 2 and the bent outer panel. 3 forms a box cross-section. The inner panel 2 and the outer panel 3 project beyond the upper flange 1 and serve to fasten the cradle stops 4. At the transition to the head pieces 5, the bogie cradle is closed by face plates 6 attached on both sides, which have openings 7 in their upper area, which are located on the inner panel 2 and the outer panel 3, and are connected to these «. On the upper boundary surfaces of Stirnplattdh 6 used as .Anschläge for the axle box housing stop plates 9 are welded,

In addition, the end plates 6 are provided with a threaded bore 10, which allows the installation of a sieve, known horizontally disposed axle suspension and allows their articulation and adjustment relative to the longitudinal member.

Furthermore, the end plates 6 are formed by their laterally outwardly drawn contour as a lifting hook 11 ·
