Definitions

the invention relates to a non-positive and positive connection between two Components, in particular connection between two different components Material
connection must be in vehicles, especially in heavily loaded rail vehicles the operational, dynamic forces, e.g. B. when braking as well as the considerably higher forces of an impact impact and starting a safety-relevant point in the train association is sufficient.
Suitable screws are z. B. expansion screws known from DIN 267.
DIN 267 For materials with lower strength than steel, e.g. B. in aluminum alloys however, it is often difficult to apply the necessary forces to the components and query.
the invention is therefore based on the object of a generic connection to improve so that this connection as possible over the entire life of the add-on parts, the imprinted preload with minimal settlement losses maintains and an automatic, unwanted loosening one with the connection attached attachment is prevented in normal operation with high security.
the non-positive and positive connection between two components consists of a carrier part 1, an attachment 2, releasable fasteners 3 and at least one pressure distributor 4.
the pressure distributor 4 used in the singular, although there may be more than one.
the Attachment 2 is on the carrier part 1 by means of the carrier part 1 and behind it arranged pressure distribution piece 4 penetrate part of the fastening means 3, in particular screw 3a, and the associated holding part of the Fastening means, in particular nut 3b, attached.
the pressure distribution piece 4 is welded to the carrier part 1. It is for the introduction of voltage and durability of the screw connection is particularly advantageous if that Pressure distribution piece 4 only after application of an intended preload with the help the releasable fastening means 3 welded to the support part 1 under tension becomes.
the pressure distribution piece 4 distributes the forces from the pretensioning of the fastening means 3 and from operational stress on neighboring components. After the welds have been produced, the releasable fastening means 3 loosened and disassembled, the welds 8 for this state Pressure distribution piece 4 proportional tensions - from the withdrawal of the preload forces - receive.
the carrier part 1 is designed as a hollow or hollow chamber profile, which has webs 5, in the immediate vicinity of the releasable fastening means (3) and parallel to the Shank of the penetrating fastener (screw 3a) are arranged.
the arrangement of the webs 5 in the immediate vicinity of the releasable fastening means 3 cause increased stiffness of the profiles in this area and allow the application of higher preload forces.
the pressure distribution piece 4 consists of at least in the welding zone Material that can be welded to the carrier part 1. It is preferable to use a similar one Material used.
the pressure distribution piece 4 can further stiffening webs 6 to increase the rigidity exhibit.
the pressure distribution piece 4 is pot-shaped. It has circumferential stiffening webs 6 in the edge area.
a pressure piece 7 in particular from the Steel, arranged.
attachment 2 consists of higher strength material than the carrier part 1. This is the case if steel parts e.g. B. joints and / or coupling brackets on aluminum structures resilient and must be securely fastened.
