AI Technical Summary

Problems solved by technology

Welding these lugs is a critical work step which can only be performed manually and in any case leads to a local weakening of the light metal profile due to the introduced heat
In addition, for light metal profiles with a wall thickness of less than 4 mm, manual welding connections are not recommended
Alternative welding methods that require less heat input, such as laser welding or friction stir welding, require a high level of mechanical effort and are too laborious for the purpose
Another disadvantage of this solution is that each ground connection is already prescribed when constructing the shell of the vehicle body, and therefore any attempt to move such a ground connection is accompanied by a considerable amount of work
This can be disadvantageous in the case of subsequent changes to rail vehicle installations or during the manufacture of different versions with different equipment specifications from a single type of vehicle body

Embodiment Construction

[0019] figure 1 An extruded profile with an L-shaped section is shown by way of example and schematically. A highly abstract oblique representation of an extruded profile 1 is shown, for example, which in combination with other similarly shaped profiles forms the undercarriage of a rail vehicle. The extruded profile 1 is designed with a shaped part 3 with an L-shaped cross-section, which is integrally molded with the rest of the profile cross-section during the manufacture of the extruded profile 1 . Holes 2 are formed in the legs of the L-shaped portion 3, by means of which holes the grounding cable can be releasably fastened using conventional fastening means (cable joint connection, screw connection).

[0020] figure 2 An extruded profile with an I-shaped section is shown by way of example and schematically. A section through the extruded profile 1 is shown, wherein the shaped part 4 has a straight I-shaped cross section.

Abstract

Disclosed is an integrally built rail vehicle body comprising at least one electric earthing point, said earthing point being designed as a bore (2) in a shaped portion (3, 4, 5, 6) of one of the extruded profiles (1) forming the rail vehicle body.

Description

technical field [0001] The present invention relates to a monolithically constructed rail vehicle body including a ground contact point. Background technique [0002] Devices provided on the rail vehicle body, such as so-called drive containers, air conditioning systems and similar equipment, must be electrically connected to the metal vehicle body. To this end, each device employs one or more ground cables (flex wires), each of which is electrically conductively connected to the vehicle body. Modern vehicle bodies are mostly of monolithic construction, in which a plurality of extruded profiles made of light metal are welded to one another in order to form the vehicle body. A grounding cable, usually with a cable gland mounted to its end, is fastened to the vehicle body by means of a screwed or clamped connection. Proper precautions need to be taken with respect to the body of the vehicle where this connection point is made. Tabs provided with holes for threaded connectio...
