    摘要: A magnetic rail brake device for rail vehicles, comprising one or more pairs of brake blocks adapted to be pulled, in operation, magnetically against the rail. The brake device is characterized by at least one permanent magnet movable up and down in a magnet housing. The magnet housing is arranged in such a manner that in rest position of the permanent magnet in the magnet housing, the magnetic field lines close through an upper portion of the magnet housing. In an operating position of the magnet in the magnet housing, the field lines can extend through pole pieces within brake block members of magnetizable material which can be brought into contact with the rail.
