Embodiment Construction

[0019] figure 1 An exemplary embodiment variant of the inventive bottom bar arrangement is shown in side view.

[0020] The bottom bar 1 is connected to a side wall (not shown) of the rail vehicle body. On the inside of the body, the bottom bar 1 is fastened to the supports of the side walls, and on the outside is welded to the side walls.

[0021] Bottom bar 1 is implemented in steel; in section its geometry has an approximate double S-shape, with straight and rounded parts arranged at right angles and obliquely relative to each other.

[0022] According to the invention, the bottom bar can also be implemented from aluminium.

[0023] The hole pattern is arranged on the bottom bar with a first hole 9 and figure 2 The second hole 10 shown in and other holes punched out along a line on the side surface 2 of the bottom bar 1 .

[0024] According to the invention, holes can also be produced by using a laser.

[0025] Furthermore, it is also conceivable to arrange grooves in...

Abstract

The invention relates to a bottom bar arrangement for a body of a vehicle, in particular a rail vehicle. In order to create favorable design conditions, according to the invention at least one bottom bar (1) with a hole pattern and at least one suspension device (3) perforated in the same way as the hole pattern interface and with U-shaped cross-section are provided, at least one of which hangs The device (3) is interlocked and frictionally connected to at least one bottom bar (1). The identical design of the interface of the bottom bar (1) and the suspension device (3) results in great flexibility in the type and number of devices (24) coupled to the body via the suspension device (3). Furthermore, the body production process is simplified and accelerated.

Description

technical field [0001] The invention relates to a bottom bar arrangement for a body of a vehicle, in particular a rail vehicle. Background technique [0002] Devices such as air conditioning systems, human waste containers, batteries, compressed air modules etc. are often arranged under the bodywork of vehicles, in particular rail vehicles, ie in an underfloor location. They are coupled to the hitch, which is welded to the bottom bar. [0003] EP 1 752 250 B1 is known in the prior art. It describes laser welding methods and also describes welded connections to outer panels and structural components of rail vehicle bodies. No suspension device is disclosed which is interlocked and frictionally connected to the body via bottom bars for the purpose of coupling the device to the body. [0004] Furthermore, DE 10 2014 113 829 A1 shows a modular fastening system for connecting an underfloor part to a rail vehicle body via fastening elements. The interface between the fastening...
