ES2261530T3 - VAGON BOX OF A LARGE VOLUME VEHICLE SPECIALLY OF A RAILWAY VEHICLE. - Google Patents

Abstract

The wagon body has a box frame of metal profiles (1), with outer and inner casing (2,3). Parts of outer and inner casing are combined into a modular unit, using positive and/or non-positive fasteners. Clearance between module and profile frame allows for compensation of manufacturing tolerances of the frame. Casing parts are manufacture from pultruded semi-finished products. The casing parts may be connected by plug, screw, adhesive, etc. The module is supported on the metal profiles in vertical direction.

Description

Wagon box of a large volume vehicle, especially from a rail vehicle.

The invention relates to a wagon box of a large volume vehicle, especially a vehicle railway, with a rib of box formed from profiles metallic, an outer covering and an inner covering, in which elements of the outer covering and elements of the Inner lining are gathered through fixing means by positive union and / or by force application to form a group structural, and between this structural group and the metal profiles of the rib of the box there is a game that compensates the Measuring tolerances of the case rib.

In the construction of railway vehicles knows, in general, form the ribs of a box of wagon to from simple metal profiles (e.g. tubes rectangular), which are connected, in general, to each other by means Welding As the outer covering of a rib of this type plates are usually used, which are fixed on the side of the wall and on the roof side in the same way through weld on the rib of the box. Since the rib and its sheet layout define the outer dimensions of the box of the wagon, close tolerances must be maintained especially in the fabrication of the rib, which causes a high technical expense and corresponding costs. In addition, in an unfavorable way, the sheet metal arrangement requires clamping, alignment and special spatula, in order to achieve optical quality Acceptable (no welding seams or welding points, no buckling).

Through European patent publication 0 146 706 is known to fix in a rib of a box of wagon, which It consists of continuous exterior walls with reinforcements that T-shaped elements are projected inwards interior cladding on spacer rails, which have elongated holes and are fixed through screws in the reinforcements of the outer wall. In this way, they can be compensated constructive tolerances between the rib of the box and the Inner liner. An inner lining is not provided in the wagon box according to this patent publication.

From EP 0 039 071 A2 it is known a wagon box with the measures of the preamble of the claim 1. In this wagon box, the outer lining and a inner lining are attached with the help of means of fixation to form a structural group. This structural group presents cavities, in which a profile is arranged in each case Metal ribbed case with a set arranged around. The connection of the structural group with the metal profiles is carried out through the filling of the cavities with plastic suitable. To get defined positions of the structural group in front of metal profiles, assembly work is necessary Expensive and auxiliary tools.

The invention has the task of configuring a wagon box of the type indicated at the beginning with respect to a favorable cost manufacturing, time saving, so that higher measurement tolerances for the rib are permissible cash flow, however, the accuracy of the coating.

This task is solved according to the invention because only the outer lining elements or only the inner lining elements are fixed by means of plug connections, threaded joints, adhesive joints or Velcro joints in the metal profiles of the rib of box.

The advantageous configurations of the invention are indicated in the dependent claims.

The advantages that can be achieved with the object according to the invention reside especially in the following points:

?

       broad independence from rough construction tolerances,

?

       work avoidance of adaptation,

?

       hour savings mounting,

?

      exterior revestment Smooth, high optical quality, can also be achieved in a large surface,

?

       simple configuration of structured surfaces (such as grooves, grooves, stretch marks)

?

       side walls arches that can be done easily

?

       simple repair and Fast in case of eventual damage.

For the rest, the following is described in detail the invention with the help of an embodiment example, which It is represented in principle in the drawing. In this case:

Figure 1 shows a wagon box in the section through the axis length of the car.

Figure 2 shows the side wall of the box of wagon in the lower part of the window, of the same week in the cross section.

In the wagon box according to figure 1, the rib of the drawer is formed by metal profiles 1 and, in concrete, here by rectangular tubes. These metal profiles 1 are connected in each case by means of welding with profiles metallic not shown, arranged in longitudinal planes and corresponding transverse.

The wagon box has an outer lining 2, which is constituted, in the exemplary embodiment, by elements of side walls 2a and 2b and by an inner ceiling element 2c. Between the side wall elements 2a and 2b are window disks 4. The car roof is completed by means of a hermetic roof cover 5. To the inner lining 3 of the wagon box belong lower sidewall elements 3a, mold elements 3b and a cover element 3c. The Coating elements 2a, 2b, 2c and 3a, 3b, 3c mentioned are connected in pairs through attachment fixing means positive and / or by force application to form in each case a structural group In the example according to Figure 2, as fixing means is provided a threaded joint 6. In a way alternative or additional plug connections, connections are suitable Velcro adhesives or joints.

Among the structural groups, which are formed from exterior cladding elements 2 and a from elements of the inner lining 3, and the profiles Metallic 1 of the rib of the box there is a set (see especially figure 2) through which they are compensated Measuring tolerances of the case rib. The groups structural cladding, which are supported in direction vertical on metal profiles 1, can be connected - through of an adhesive bond 7 between the respective element (here 2a) of the outer lining 2 and metal profile 1. Conversely, also the respective element (for example 3a) of the coating interior 3 can be connected to the metal profile 1 through accession. As an alternative to adhesive joints are offered, by example, threaded joints or Velcro joints. In the lower element of the side wall 2a of the outer liner are integrated 8 holes for water outlet.

The outer lining elements 2 and the Interior lining elements 3 are manufactured with Preference from extruded semi-finished products. Such extrusion profiles may, for example, have a length of 7000 mm, a width of 1400 mm and a total thickness of 100 mm. further of the braids of fiberglass material, which are arranged in parallel, it is recommended to use fiberglass mats, glass fabric or glass inlay to increase resistance cross section of coatings 2 and 3. With respect to current requirements in the field of rail vehicles, for example in relation to fire behavior and to the hydrolysis resistance can be used as a resin system, unsaturated polyester resins (UP), epoxy resins (EP) or phenol resins, where light fillers reduce the specific weight Colored extruded profiles guarantee also in the case of small scratches a good optical quality of the coatings The outer lining elements 2 may present fixing options for mounting parts exterior, for example for skirts, water channels and slats as decoration. In a corresponding way, the elements of inner lining 3 may be provided with possibilities for fixing interior mounting parts, for example for cable channels, lights or speakers.
