Abstract

A modular side wall of a car body, in particular for rail vehicles, consists of modular sections (1, 2) whose components - such as upper belt (3), lower flange (4), frames (5), blind field sheets (6, 7), purlins (8) and optionally also longitudinal profiles (9) for accommodating passenger seats and fastening elements (10) for roof units - a mountable exclusively by cold joining technology with high accuracy fit kit in which all joints necessary for cold joining, preferably by introducing rivet holes, in the prefabrication of said Components (3 to 10) are generated.

Description

The The invention relates to a modular side wall of a car body, especially for Rail vehicles, and a method for producing such Side wall.

Between The manufacturers of rail vehicles and their customers often conclude so-called local content contracts, in which the manufacturers undertake to manufacture their vehicles a defined part of the added value in each country of the To provide customers. This obligation can be fulfilled by that the manufacture of vehicles in the country of customers by joining together Completely Supplied assemblies (base, side walls, end walls, roof, vehicle head) takes place. A production of these assemblies, such as the side walls, im Customer's country is common a problem because locally fully equipped manufacturing workshops and qualified personnel are missing.

Of the Invention is based on the object, a side wall in such a way, that they are on as possible simple, inexpensive Way to individual customer requests can be adjusted and without complex technical equipment and qualification of the personnel at any manufacturing locations manufacturable is.

These The object is achieved by a side wall having the features specified in claim 1. in this connection If the side wall consists of modular sections whose components - such as Lower flange, frames, blind field sheets, purlins, and optionally also longitudinal profiles to accommodate passenger seats and fasteners for roof units - one exclusively by cold joining technique represent a kit which can be fitted with a high degree of accuracy. This is possible, because with this kit all for Cold-joining necessary joints, preferably by introducing rivet holes, during prefabrication said components are generated.

The in claim 9 indicated method for producing a modular constructed side wall with the aforementioned features is characterized by mounting a module section in cold joining technology by aligning the ribs, placing the upper belt, the lower belt, and the inner blind sheets, Pre-positioning by setting selected rivets, finished riveting, Placing the purlins and the outer blind sheets and final Rivets in the area of the inner blind sheets.

advantageous Embodiments of the side wall according to the invention are in the dependent claims 2 to 8 indicated.

The Sidewall according to the invention can be easily adapted to individual customer requirements be adjusted by, for example, the frames of the kit the desired outer contour the car body have corresponding bends. Further advantageous is the side wall by cold joining the Kit easy and quick to install. This assembly can be on performed at any location being, with neither fully equipped production facilities for rail vehicles yet Skilled personnel needed become.

in the Further, the invention will be described in more detail with reference to an exemplary embodiment, which is shown in principle in the drawing. Show it

1 a side wall of a car body in perspective view on its outside,

2 the sidewall rotated by 180 ° 1 in perspective view on her inside.

The sidewall shown has two module sections 1 and 2 , In the exemplary embodiment, this side wall is arched outwards and intended for a car body, which has a raised floor section (high-floor area) arranged above a bogie and an adjoining low-floor floor section (low-floor area). Accordingly, the lower module section belong 1 to the high-floor area and the higher module section 2 to the low-floor area of the car body. Connecting the two module sections 1 and 2 serves a connection tab 14 , each by rivets on adjacent longitudinal sections of the module sections 1 and 2 is attached. It is understood that a non-curved, flat side wall and module sections with the same height are possible.

Each module section 1 and 2 consists of a top chord 3 , a bottom strap 4 , Ribs 5 , inner dummy panels 6 , outer blind plates 7 , Purlins 8th , Longitudinal profiles 9 for holding passenger seats and fasteners 10 for the connection of roof units, whereby the longitudinal profiles 9 and the fasteners 10 optional. In addition, in the door area, a stiffening element 11 be arranged. The aforementioned components of the module sections 1 and 2 have a high intrinsic stability and are a kit that can only be assembled using cold joining technology. All for cold joining of the module sections 1 and 2 necessary joints from this kit are included the prefabrication of said components 3 to 9 and possibly also 10 and 11 produced with high accuracy of fit, and in particular in the sense of grids by introducing rivet holes for preferred blind rivets and blind rivet nuts. By using modern production technologies (such as laser cutting processes) it is possible to achieve such a high accuracy of fit that the module sections 1 and 2 can be assembled without the usual in wagon construction mounting devices.

The upper strap 3 , the lower belt 4 and the blind field sheets 6 and 7 consist of CNC-bent and bevelled sheets. The frames 5 are made of metal profiles or rectangular tubes by bending and 3D laser cutting. The upper frames 5 and also the end frames 5 have roof-side by low-distortion laser welding mounted quick-mounting coupling elements 11 made of investment casting, which is a cold-operable interface 15 for connecting a roof. At the lower frames 5 and at the end frames 5 are base side quick-assembly coupling elements 12 attached by low-distortion laser welding, which is a kaltfügbare interface 16 for connecting a base frame. The purlins 8th and the longitudinal profiles 9 To accommodate passenger seats consist of sheets and are manufactured by 2D laser cutting and folding. The outer end frames 5 the module sections 1 and 2 are additionally each as interfaces 17 designed for a quick mountable connection of an end wall or a vehicle head, these interfaces 17 into the end frames 5 may contain welded sockets.

The joints contained in the supporting structure of the side wall and the rivets arranged there, especially the blind rivet nuts, define advantageous grids and thus provide the ability to provide the side wall in a flexible manner with an outer lining and an inner lining. The components of the aforementioned coverings can be held in the threads of the blind rivet nuts. A further completion of the side wall is quite possible, for example by mounting windows, seats, cables and insulation, so that ultimately a fully equipped side wall at the joints 15 . 16 and 17 is connected to the roof, base frame, end wall and vehicle head.

The assembly of the load-bearing structure of each of the two module sections 1 and 2 in cold joining technique is done by aligning the frames 5 , Putting on the upper strap 3 , the lower girth 4 and the inner blind sheets 6 , Pre-positioning by setting selected rivets, finishing riveting, placing the purlins 8th and the outer dummy panels 7 as well as final riveting in the area of the inner blind sheets 6 ,
