Abstract

A component comprising a first portion, a second portion and a third portion, at least one of which is formed of a titanium material and at least one further portion of an aluminum material, wherein the second portion extends between the first and the third portion and the second Section against the first and the third section force, form or frictionally fixed.

Description

The invention relates to components for vehicles movable on the ground, on the water or in the air.

By the DE 10 2004 026 228 B4 a component has become known comprising a first region of a titanium material and a second region of an aluminum material, wherein the first region and the second region are materially interconnected and wherein the first and the second region by a running in the aluminum material of the second region deep welding process or heat conduction welding process in combination with a triggered by a heat flux from the aluminum material towards the titanium material diffusion process are materially interconnected.

The vehicles mentioned above are subject to dynamic stresses, so that it can happen that the cohesive connection does not bring sufficient service life of the component, but in particular cracks can occur in the cohesive connection region.

It is generally known that certain aircraft manufacturers use extruded titanium seat rails as an alternative to aluminum seat rails, since the aluminum material is subject to increased corrosion, for example under the action of liquids such as cola or the like. In pure aluminum seat rails thus very high maintenance costs are given.

The invention is based on the object, starting from the DE 10 2004 026 228 B4 to provide an optimized component that no longer includes the disadvantages of the prior art.

This object is achieved by a component comprising a first portion, a second portion and a third portion, at least one of which is formed of a titanium material and at least one further portion of an aluminum material, wherein the second portion between the first and the third section extends and the second portion with respect to the first and the third section by force, form or frictionally fixed.

Advantageous developments of the subject invention can be found in the dependent claims.

Advantageously, the second section for forming a double T-profile runs approximately perpendicularly between the first and the third section.

According to a further aspect of the invention, the mutually parallel first and third sections are provided with groove-like profiles for receiving the end regions of the second section, wherein, if necessary, the end regions of the second section facing the first and third sections may be contoured.

Notwithstanding the prior art, no cohesive connection is made, since selbige as stated above, may be subject to problems in terms of life.

Advantageously, the firm connection between the three sections is brought about by introducing, after the introduction of the as required contoured end regions of the second section, into the respectively associated groove-like profile of the first and third sections, for example by rolling.

The component according to the invention can first of all be used to receive objects in each region of a vehicle mentioned at the beginning, wherein the component is preferably designed as a seat rail for receiving a seat in the vehicle concerned.

It is particularly advantageous if the component is a seat rail for receiving an aircraft passenger seat, since in this area the highest demands on weight reduction and corrosion resistance, respectively service life, is given.

In order to avert the aforementioned corrosion problems, at least that section of the component which faces the respective seat, in particular the aircraft passenger seat, is made of the titanium material.

To facilitate the production, it may be useful to generate the component from three unwound from the coil sheet metal sections.

The subject invention is illustrated by means of an embodiment in the drawing and will be described as follows. Show it:

1 Schematic diagram of the component according to the invention;

2 Schematic diagram of the manufacturing process of the component according to the invention;

3 and 4 Schematic diagrams of the connection technology of the individual sections.

1 shows the component according to the invention 1 consisting of a first section 2 one second section 3 as well as a third section 4 , In this example, the component should 1 be designed as a double-T-carrier. Also in this example is the first section 2 made of a titanium material and the second and the third section 3 . 4 be formed of an aluminum material. Between the sections 3 . 4 are connection areas 5 . 6 given, which can be generated either force, form or friction.

It is possible in principle, according to DE 10 2004 026 228 B4 the connection areas 5 . 6 can also be produced by cohesive connections, which may be given only a reduced service life in terms of fatigue strength under dynamic loads.

Compared to the components formed from pure aluminum materials of a male member, such as a seat, facing first section 2 , made of a corrosion-resistant material, namely a titanium material.

2 shows a schematic diagram of an indicated manufacturing method for the component according to the invention 1 , Visible are three coils 7 . 8th . 9 where the coil 7 a wound titanium sheet involves while the coils 8th . 9 include wound aluminum sheets. In the right part of the 2 is the component according to the invention 1 recognizable, containing the sections 2 . 3 . 4 ,

The 3 and 4 show in detail how the sections 1 . 2 and 3 to get prepared. In the sections 2 and 4 becomes in those the section 3 facing surface areas 10 , a profile-like groove 11 brought in. This can be done for example by rolling, since the material is easily deformable.

In the vertical section 3 become the end areas 12 . 13 for example, by profiled rollers with a corresponding counter-profile 14 . 15 Mistake. In particular 3 can be seen, is the respective contoured end 14 . 15 of the section 3 into the associated groove 11 of the respective section 2 . 4 brought in.

In 4 is indicated, such as the section 4 with the section 3 after insertion of the end region 15 in the groove 11 through roles 16 is added. This applies equally to the end area 12 of the section 3 ,
