Definitions

• the present invention relates to a rail vehicle for transporting unit loads, in particular road loads such as road vehicles, containers or swap bodies, the main characteristic of which is its very low ground clearance over practically its entire width. So that railway rolling stock can circulate without problem in tunnels or under bridges, rail networks establish one or more jigs which delimit the outline or the envelope inside which the material must be included. Compliance with this template provides the guarantee for rolling stock never to encounter a fixed obstacle.
• UIC gauge International Union of Railways
• UIC gauge International Union of Railways
• Rolling stock that complies with this UIC template can circulate on almost all European networks without risk.
• the lower part of the various templates presents few differences between them from one network to another, on the other hand, in the upper part, some networks (Germany, Austria, ...) have a much larger template than the UIC template for historical reasons.
• freight wagons for example flat wagons, which comply with the UIC gauge when empty, can be loaded with goods which exceed the UIC gauge but respect the gauge of the network in question, if the journey is made only on this network.
• the template in the lower part mainly constitutes two sides inclined at 45 °.
• the surface where the tires of the truck or the base of the container rest is approximately 2.5 to 2, 6 m (at least roughly equal to the distance between the outer sides of the tires).
• a surface of this width is at best only about 15 cm above the minimum admissible level for the underside of the rail vehicle, resulting in a loss of useful height making it impossible to transport a vehicle or container four meters high.
• One of the objectives of the invention is to allow rail transport of all four-meter-high vehicles not relating to exceptional transport. Another objective is to lower the point of contact of the load with the bottom of the wagon as much as possible.
• Figure 1 is a cross-sectional view of the rail vehicle according to the invention loaded with an articulated vehicle formed of a truck and a trailer on which the standard template has been drawn in thick lines and the lower part of this template in an even thicker line; .
• Figure 2 is an enlarged view of the detail circled in Figure 1;
• FIG. 3 is a diagram showing the general appearance of the standardized template according to the reference contour;
• Figure 4 is the enlarged layout of the lower part of the template shown in Figure 3;
• Figure 5 is the layout in correspondence with that of Figure 4 of the template corresponding to the rail vehicle with very low ground clearance and maximum width of the supporting structure according to the invention.
• the invention relates to a wagon 1 and more generally a railway vehicle having a supporting structure 2, for example a chassis.
• the body of the carrying structure 2 delimits in the lower part a loading platform 3 with a bottom 4, for example flat, which can be pivotally pivoted and / or lowered to the ground at one of its ends to carry out self-loading and self-unloading wagon per wagon.
• the lower limit of the flat bottom platform 3 4 is inscribed in the lower part of the standardized template.
• the width of the bottom 4 of the platform 3 is equal to the width of the standardized template.
• the rail vehicle 1 is intended to transport a unit road load, for example an articulated road vehicle formed by a tractor 5 and a trailer 6, but also one or more container (s) or box (es) mobile (s) or other load (s) traveling on the roads or transported on them.
• the standardized railway gauge shows a general shape of the reference contour as shown in FIG. 3.
• connection portion 9 is a broken line made up of three straight segments in series 11, 12 and 13 of inclination increasing downwards until the junction with the corresponding lateral vertical side 10.
• the template continues down and on each side by a first step 14 towards
• the template then continues downwards and on each side by a small lateral side 16 followed by a second recess 17 further reducing the width of the template even further to a width "d min".
• Each second recess 17 is connected to a bottom line 18 by an oblique line 19 at an angle of 45 ° inwardly delimiting a recess representing another recess or shoulder 20 in the corner for a platform in the lower part.
• the lower limit represented by the bottom line 18 is located in this example at a distance E of 13 cm from the ground.
• the entire template is of course symmetrical with respect to the axis of the tracks materialized by an axis of symmetry 21 perpendicular to the plane of the tracks and cutting it in the middle.
• One of the objectives of the present invention is to lower the contact surface of the load with the supporting structure to the lowest possible level of the gauge, ie a few centimeters from the ground, for example at a distance "e" of approximately 8 to 10 cm from the ground. Because of the necessary width of the floor of approximately 2.5 to 2.6 cm, the size of the rail vehicle comes out of the template. But if we limit our not to exceed the upper point of the oblique side 19 inclined at 45 ° (at the height of 400 mm in height and 1250 mm in half width, from the reference contour of the UIC template), we do not come hit the widespread 385 mm high docks which arrive just in this corner.
• the platform 3 of the rail vehicle is shaped so that its flat bottom 4 is as low as possible, that is to say very close to the ground , at a distance "e" of a few centimeters, for example 8 to 10 cm from the ground, giving the railway vehicle very little ground clearance.
• the surface of contact of the load with the bottom (4) of the supporting structure of the rail vehicle is at least at the height or below the bottom line 18 of the standardized gauge.
• the width of the gauge of this railway vehicle is greater than the widest track existing for a road vehicle authorized for normal free road traffic, that is to say without accompaniment of the exceptional convoy type.
• the width of the platform 3 carrying the load has the maximum useful dimension "d lim", in any case at least equal and at most slightly greater than the track of the road vehicle of larger size authorized on the road network, for example an articulated truck-trailer vehicle or a semi-trailer or others. Well understood, this width is less than the width of the gauge of the railway vehicle.
• Lateral edge structures 22 and 23 present on each side ensure the safety of running and the lateral protection of the unit road load of the rail vehicle.
• lateral edge structures 22 and 23 are inclined rising upwards, each delimiting with the bottom 4 of the platform 3 an obtuse open dihedral, one of the two planes being that of the platform 3 and the other that of the adjacent lateral structure 22 or 23.
• these structures are inside the standardized railway gauge so that all the high platforms are compatible.
• the tires such as 24 of the tractor truck 5 come to rest on the platform 3 at the limit of the dihedral edge and the inclined planes of lateral border widen the space in width upwards so to leave a free space for the rocker panels of the transported road vehicles.
• these lateral border structures 22 or 23 continue vertically upwards to a small height as shown in Figure 1.
