摘要

The eddy current rail track brake has an adjustment bearing for holding the eddy current brake magnet 1 in its operative position, which bearing comprises a first adjustment part 33 on the eddy current brake magnet and a second adjustment part 34 on a non-sprung vehicle part. The first, upper adjustment part 33 is connected to the eddy current brake magnet 1 in a vertically and horizontally adjustable fashion, whilst the second lower adjustment part 34 is guided in a vertically displaceable manner on the non-sprung vehicle part 25 and can be lowered counter to the pretensioning of a pretensioned spring 30. The excitation of the eddy current brake magnet can be reduced as the travel speed decreases, in such a way that the attraction force does not exceed a specific maximum value. The pretensioning of the spring 30 is dimensioned to receive this attaction force without further compression of the spring 30. If the reduction of the excitation of the eddy current brake magnet 1 fails, the extremely high attraction force which occurs when the vehicle is travelling slowly or is stationary compresses the spring 30 and the eddy current brake magnet moves to the emergency position resting on the rail. As a result, overloading of the carrier elements of the eddy current brake magnet 1 is prevented.
