Embodiment Construction

[0048] figure 1 A side view of the cockpit without the outer skin is shown schematically. The intermediate buffer coupling is also omitted for overview reasons. The inner skin 701 is constructed in two pieces. This division is made above the retaining wall reinforcement 711 in the horizontal direction. The upper part of the inner skin 701 has openings 704 for the front glass and openings 703 for the side windows. The window openings are separated from each other by A-pillars 705 . Ring beam 720 is shown above the upper portion of the inner skin. The ring beam is fastened releasably via connecting elements 721 to the upper longitudinal beam of a following body part (not shown).

[0049] Integrated in the lower part of the inner skin are a wall reinforcement 711 and a non-directional strip 710 , which transmits forces from the wall reinforcement 711 at the insertion point 712 into the lower side members of the following body part.

[0050] The lower crash-conducting elemen...

Abstract

The invention relates to a connecting element for fastening connection pieces to fiber composite components made of at least one fiber layer and of matrix material, the connecting element having a screw- or bolt-like shape, the connecting element comprising a tip at one end thereof, which tip supports the penetration of the fiber layers of the fiber composite component in the dry or matrix-impregnated, unconsolidated state, and comprising a casing in the region that comes in contact with matrix material of the fiber composite component, but at least in the region that comes in contact with the reinforcing fibers of the fiber composite component.

Description

technical field [0001] The subject matter of the invention is a connecting element by means of which a connecting part can be connected to a fiber composite structure, in particular a special ring beam structure made of fiber composite material. The ring beam is part of the structure of the head module (or cockpit) for a rail vehicle and should contribute to reducing and distributing the resulting loads in the event of a crash. Background technique [0002] The locomotive module is used especially in the construction of short-distance traffic trains, especially subways. In such trains, the locomotive module is usually integrated into the carriage. The front module is also referred to as the cockpit. [0003] Advantageously for material and energy efficiency, the principles of lightweight materials and lightweight construction have been increasingly implemented in the construction of rail vehicles in recent years. In particular, the use of fiber composite materials is incr...
