Embodiment Construction

[0061] figure 1Schematically shows a side view of the cabin without the shell. For reasons of clarity, the intermediate buffer coupler has also been omitted. The inner shell 701 is constructed in two parts. The division is made in a horizontal plane above the guard bar reinforcement 711 . The upper part of the inner shell 701 has an opening 704 for the front windscreen and an opening 703 for the side windscreens. These window openings are separated from each other by A-pillars 705 . A ring beam 720 is shown above the upper part of the inner shell. The ring beam is fastened releasably via connection elements 721 to the upper longitudinal beams of the subsequent body part (not shown).

[0062] Armor reinforcement 711 and UD strap 710 are integrated into the lower part of the inner shell, said UD bands transmitting forces from arm reinforcement 711 at insertion point 712 into the lower side members of the subsequent body part.

Abstract

The subject of the invention is a method for connecting a connecting piece to a U-shaped ring beam for a head module of a rail vehicle, wherein the head module consists essentially of fiber-reinforced plastic material and has a skin, and the The ring beam is made of fiber-reinforced plastic material and is arranged as reinforcement in the top region of the housing. The method provides that connecting elements are guided through the dry or matrix material-impregnated, unconsolidated fiber-reinforced structure of the ring beam.

Description

technical field [0001] The subject matter of the invention is a method by which a connecting element can be connected to a special ring beam structure made of fiber composite material for connection to a subsequent body part having a ring beam. The ring beam is part of the structure of the head module for the rail vehicle and is intended to help reduce and distribute the occurring loads in the event of a crash. Background technique [0002] In particular, the head module is the structure of a short-distance train, especially a subway. In such trains, the head module is usually integrated into the carriage. The head module is also referred to below as the cabin. [0003] Due to material and energy efficiency considerations, the use of lightweight materials and the principle of lightweight construction have become increasingly popular in rail vehicle manufacturing in recent years. In particular, the use of fiber composite materials is increasingly growing. This also applie...
