AI Technical Summary

Benefits of technology

[0004]It is an object of the invention to provide devices and methods for rail vehicles, which allow a universal and simple coupling to the rail vehicle with optimum procedure of an attached device in operation.

[0089]In summary, some aspects of the present invention allow the attachment of components to a rail vehicle in advantageous manner. Among other things, the invention is based on the realization that the shaft of a rail vehicle can advantageously be used for attaching a device, in particular electronics. The attachment of the device in particular has to be very robust, but offer contact surface with the shaft as small as possible. Hereby, water accumulations are avoided, thereby reducing the corrosion of the shaft. A notch effect on the shaft should absolutely be avoided. Similarly, damage to the varnish should be absent. A band used for attachment can be manufactured from steel. However, then, it is convenient to use a further material such as for example a polymer or the like on the inner side of the steel band, thus the side facing the shaft. It could have a knob profile or else a car tire profile on the side facing the shaft. Hereby, the contact surface is further reduced and the materials are protected. As the attachment material, in particular softer materials than that of the shaft or of the varnish layer on the shaft come into consideration. Knobs and tire profiles also can be used on the side facing the steel band since here too corrosion aspects can be relevant. The attachment of the device to the shaft should be slip-resistant.

Problems solved by technology

In addition, many measuring and testing devices require an access as unimpeded as possible to the or into the rail vehicle and away from the rail vehicle or out of it, for example to transmit data via radio.

Generally, measuring and / or testing devices are therefore attached in an upper outer region of the rail vehicle, however, which is associated with great difficulties due to very different and optionally varying superstructures on the rail vehicle.

Certain possibilities of attachment, for example to the chassis, only come into consideration with additional safety tests, which makes these attachment mechanisms expensive and unattractive.
