ES2551660A1 - Crossbeam for metric gauge ballast track and railway (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Crossbeam for ballast track with metric gauge and railway track. The present invention has its application within the industrial sector dedicated to the manufacture of railway tracks and sleepers used in these tracks and, more specifically, the invention relates to a sleeper with application on railway tracks, and specifically, in railroad tracks of metric gauge. The invention provides a sleeper capable of stabilizing the track in all three directions and, in a special way, in the transverse direction, the least studied of the three. Through a screed, the sleeper is able to develop the necessary effort to cope with the instabilities originated in the transverse direction by the actions to which the road is exposed. In a first plane, the invention provides solutions to the transversal dynamics of the track, in a second plane, to the longitudinal dynamics and in a third plane, to the vertical dynamics of the track, to the latter in a less predominant way since it will use elements known in the art.

The embodiment of the crossbeam shown corresponds to the embodiment of Figure 1, so that the fixing means (3) formed by the angled plate (7), the seat plate (6) are visible at the left distal end of the crossbar. ), and an elastic clip (9) which reflects a curved arrangement by which it hugs the bolt. On the other hand, at the right distal end, the bent plate (7), the seat plate (6) and a screw as a fixing element (8) can be seen as fixing means (3).

Figures 3a and 3b show schematic views of the crossbar, respectively, the longitudinal section of the crossbar and its plan view. In both figures the recesses can be seen

(11) practiced along its distal ends and that correspond to the adaptations provided on the upper surface of the crossbar in order to support the rails (1) of the railway track and receive the fixing means ( 3) for coupling the rail (1) to the crossbar.

In Fig. 4, the invention shows one of the preferred embodiments of the crossbar in which said crosspiece has a cross-sectional extension (11) of rectangular section in its center. Thus, the crossbeam increases the contact surface and improves its behavior in its transversal and longitudinal dynamics.

Finally, it should be noted that despite the fact that in all the figures shown the new ones

(4) are arranged on the lower surface of the area defined by the crossbar in correspondence with the rail (1), each of the recesses (4) can be arranged in any position of each of the halves of the crossbar provided that said position be a position away from the center and the end ends of the sleeper.

In the same way, despite the fact that in all the figures there are recesses (4) of rectangular section, any other type of section is possible, as long as they have a base or length l2 sufficient to fulfill the function of support, distribution of load and stabilizing element for which they are configured.

Finally, in view of this description and figures, the person skilled in the art may understand that the invention has been described according to some preferred embodiments thereof, but that multiple variations can be introduced in said preferred embodiments, without departing from the object of the invention as claimed.
