Definitions
- the invention relates to a long beam for one
- Rail vehicles in particular passenger vehicles, are often manufactured today as self-supporting metal structures in what is known as an integral construction, in which a body consists of individual large components such as the base, walls, roof and end walls made of light metal.
- Extruded profiles is composed. Both horizontally and vertically oriented profiles are used, which are typically welded to one another. These profiles are designed taking into account the locally required strength and usually include one or more closed profile chambers. Here are at the
- Concentrations of tension at the corners of the door openings are subject to various design measures.
- the wall thicknesses of the light metal extruded profiles can be increased or reinforcing components are welded to the door corners. Both measures have significant disadvantages.
- an increase in the wall thickness of the light metal extruded profiles also causes an increase in the vehicle mass, on the other hand, the strength is also increased in places that do not need this.
- the welding of reinforcement components is at
- Vehicle manufacturing is a time consuming and expensive
- the invention is therefore based on the object
- Integral construction can be produced.
- the task is carried out by a long girder for a
- a long girder for a rail vehicle body is described, which is divided into two partial girders along its longitudinal extent is, with a first subcarrier over the entire
- Longitudinal extension extends, and wherein a second sub-carrier is divided into at least two longitudinal sections, each having different strength.
- a long beam is made up of individual
- Metal profiles constructed, with a first profile (first sub-carrier) extends over the entire longitudinal extent. At least two further profiles are to be arranged on this profile and thus parallel to the first profile and firmly connected to the first profile. Such is a
- Long beam according to the invention constructed from at least 3 metal profiles.
- the different strengths of the individual profiles of the second subcarrier can also be the same
- Outer contour of the cross section of the profiles can be produced in different ways.
- the profiles can each have a different cross-section inside (changed
- Wall thicknesses, additional webs, modified webs) or it can alternatively or additionally another material can be used. In the latter measure, attention must be paid to the weldability with the other profiles.
- Fig.l shows an example and schematically a strong
- Long beam 1 is constructed from a first partial beam 2 and a second partial beam 3.
- the first sub-carrier 2 is exemplified as a metal profile with a U-shaped
- the second sub-carrier 3 also has a U-shaped cross section.
- the second is
- Part carrier 3 divided into two longitudinal sections, a first section 4 and a second section 5
- the two sections 4, 5 and first sub-carriers 2 are strung together.
- the two sections 4, 5 and first sub-carriers 2 are designed for connectivity by welding in the position shown. In this
- Fig. 2 shows an example and schematically one
- Integral construction is made up of a plurality of light metal extrusion profiles.
- the side wall is constructed from a plurality of side wall profiles 6, which are arranged between an upper beam 1 arranged at the top on the roof side and a long beam 1 arranged below at the base side.
- a door passage is provided in the middle of the side wall and is delimited on both sides by door pillars 7.
- Long beams 1 each comprise a first partial beam 2 extending over the entire length of the side wall and a multi-piece second partial beam 3.
- the second partial beam 3 is made of reinforced second ones at those positions to which the door pillars 7 are connected
- Sections 5 constructed, in between the second sub-carrier 3 is composed of first, non-reinforced sections 4.
- Fig. 3 shows, by way of example and schematically, a long beam at the position of a door pillar connection.
- a long beam 1 is shown, which is constructed from a first partial beam 2 and a second partial beam 3.
- Part carrier 3 is divided in sections into first sections 4 and a second section 5, these sections 4,
- Fig. 3 shows a machined long beam, on which after the sections 4, 5 and the first partial beam 2 have already been milled
- the second section 5 is machined to form a door corner and the right first section 4 within the door opening is also machined.
- Fig. 4 shows, by way of example and schematically, the cross section of an extruded light metal profile, which is provided as the first section 4 in the long beam 1 from FIG.
- the profile is constructed as a multi-chamber, closed hollow profile, in which chambers are stiffened with diagonally arranged webs.
- a C-rail is formed, to which further assemblies can be attached using sliding blocks. Formations extend downwards, which are suitable for connecting side panels.
- Fig. 5 shows, by way of example and schematically, the cross section of an extruded light metal profile, which is provided as the second section 5 in the long beam 1 from FIG.
- This profile has the same outer contour as the profile of the first section 4 shown in FIG. 4, but it is made stronger than this.
- the wall thickness at the connection point to a door pillar is made much thicker, but there is no need for the formations for connecting side panels, since these are not required at the positions of a door pillar.
- Fig. 6 shows, by way of example and schematically, a long girder.
- a longer section of a long beam 1 is shown, as it is known as a so-called above a door opening Roof rails at the junction between one
- the first sub-carrier 2 is also designed as a closed light metal extruded profile with several chambers.
- the cross section of the first sub-carrier 2 is also designed as a closed light metal extruded profile with several chambers.
- Section 4 corresponds to that shown in Fig.4.
- the reinforced second sections 5 are shown in FIG.
- Fig. 6 shows the long beam 1 in cutting already done
