Definitions

  • the invention relates to a method for non-positive connection and a frictional connection of two components, in particular connection of two components of different material
  • connection must in vehicles, especially in heavily loaded rail vehicles the operational, dynamic forces, such. B. when braking as well as the significantly higher forces of a collision shock and start at a safety-relevant point in the train suffice.
  • the invention is therefore an object of the invention to provide a method for frictional connection of two components and to improve a compound prepared in such a way that this compound as possible over the entire life of the attachments maintains the impressed bias with minimal settlement losses and an automatic, unwanted loosening of attached to the attachment attachment in normal operation with high security is prevented.
  • the non-positive connection according to the invention between two components consists of a carrier part 1, an attachment 2, releasable attachment means 3 and at least one pressure distribution 4.
  • the pressure distribution 4 is used in the singular, although it may be several.
  • the attachment 2 is on the support part 1 by means of the carrier part 1 and arranged behind it Druckverteil choir 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 particularly advantageous for the voltage input and durability of the screw when the Druckverteil Anlagen 4 is welded only after application of a proposed biasing force by means of the releasable fastening means 3 with the support member 1 under tension.
  • the Druckverteil committee 4 distributes the forces from the bias of the fastener 3 and the operational stress on adjacent components. After the production of the welds, the releasable attachment means 3 can be loosened and disassembled, for which state the welds 8 on the pressure distribution piece 4 proportional stresses - from the withdrawal of the preload forces - received.
  • the support member 1 is formed as a hollow or hollow chamber profile, the webs 5, which are arranged in the immediate vicinity of the releasable fastening means 3 and parallel to the shaft of the penetrating fastening means (screw 3a).
  • the arrangement of the webs 5 in the immediate vicinity of the releasable fastener 3 cause increased stiffness of the profiles in this area and allow the application of higher biasing forces.
  • the pressure distribution piece 4 consists, at least in the welding zone, of a material which can be welded to the carrier part 1. Preferably, a material of the same material is used.
  • the pressure distribution piece 4 may have further stiffening webs 6 for increasing the rigidity.
  • the pressure distribution piece 4 is pot-shaped in a preferred embodiment. It has circumferential stiffening webs 6 in the edge region.
  • a pressure piece 7 in particular made of the material steel.
  • the object of the invention is particularly advantageous if the attachment 2 is made of a material of a higher strength than the carrier part 1. This is the case when steel parts z. B. joints and / or coupling brackets to aluminum structures must be able to be fixed and reliable.
