EP0846606A1 - Segmented shell construction with float mounted liner - Google Patents

Abstract

The shell segments (18) are connected from the outside to a supporting skeleton structure consisting of floor assembly, pillars or ribs and end walls. The shell segments, in the load bearing combination, absorb the shear stresses. A floating inner shell (10) is connected to the load bearing outer shell (9) by shear-resistant and flexurally or compressively yielding angle pieces (12). The shell segments may be interconnected by reinforcing edges undertaking the function of a supporting skeleton structure.

Description

The invention relates to a segmented shell construction with floating inner lining, in particular for rail vehicles.

It is known that the car bodies predominantly from the Large sub-frame assemblies, two side walls, roof shell and put two end walls together. Because of the size These assemblies are large and expensive to manufacture Manufacturing facilities required. To reduce these costs it has long been common to have car bodies in similar verticals to divide divided segments (EP 0 360 585; DE 1 630 595 A1; Forecast on structural behavior for a composite city bus in GRFP ", I. Crivelli et al, Composite Manufacturing Vol.1 No 1 March 1990). Furthermore, the Interior of the well-known body shells due to the lack of accessibility of the interior problematic from the outside. The interior fittings are done in a known manner the door openings, at best through roof openings and Openings made in the end wall area. The assembly of completed assemblies with attached Interior fittings have so far failed due to the necessary joining technology. Hot joining techniques such as welding are eliminated because of the risk of damage to the interior and the Accessibility.

EP 0489 294 A1 describes a car body with a continuous Floor and roof rails described, in which the Long girders each successive ring frame and U-shaped Shells in the form of the car body profile below the window parapet and U-shaped shells in the shape of the Car body profile attached above the upper window parapet will. The supporting structure is made up of the continuous Long girders and the ring frames connecting them formed, with no previous installation of equipment components is provided in these segments. At this known construction is not a side wall in the original Sense there. The ring frame and the windows connect the roof and floor group. As a disadvantage turns out that the sidewall structure doesn't meet the requirements the UIC with regard to the noise and sound insulation of Rail vehicles completely fulfilled. It is necessary, to provide a separate inner shell and insulation. Equipment components can not in the sidewall and Roof segments are integrated.

EP 0260 200 describes a car body with longitudinally running continuous floor and roof side members and associated with them Floor and roof cross members as well as vertical column profiles described the load-bearing structure form. Similar segmented sidewall, roof, and Floor shell elements are as (aluminum) sandwich components designed with honeycomb core and frame profiles. On the Fastening of the side wall and roof segments is done in this Documentation not discussed in detail. The down demountable segmented floor assembly is form-fitting educated. With this body construction too UIC guidelines regarding sound and heat insulation are not met without a separate inner shell and insulation. In There are no references to this document, equipment components in the side wall and roof segments before Integrate assembly of the car body.

The object of the invention is a segmented shell construction with floating inner lining of the entrance to create the type mentioned, in which the manufacturing and Assembly effort is reduced, buildings and others Investment costs for manufacturing and assembly saved , a variable "modular" design of the car bodies by creating the number of segments, making one of oversized segments from one tool, one "open" structure and a high accessibility of the Vehicle interior is possible and floor, seats, units in front Assembly of the side walls can be assembled, a variable material selection for the segments is possible, Outer and inner shells, insulation and fittings and possibly Windows can be made from only one material a simple disassembly or a simple known joining process Component replacement and a recycling-friendly construction becomes possible.

The object is achieved by the features of Claims resolved, i.e. that shell segments like Side wall shell segments, roof shell segments and side wall roof shell segments with a floating inner shell as complete parts from the outside on a structural framework be mounted, the shell segments due to their compact Structure and through their connections with each other and their connections with the supporting association are mainly those Take over thrust loads, with the floating inner shell through shear-resistant, flexible or pressure-sensitive Thrust angle is formed and the connections of the shell segments with each other through stiffening and covering profiles be used and in further training the Connections of the side wall roof shell segments with one Roof center longitudinal beams are formed from upwards or connecting folds directed below, each with their vertical and horizontal folding surfaces on the parallel contact the surfaces of the central roof rail and with known means such as welding, riveting, gluing are put together.
