  • Patent number: 11312401
    Abstract: An electromagnetic rail brake device of a rail vehicle having at least one brake magnet which has a magnet coil body and at least one magnetic core, and wherein the magnet coil body carries at least one magnet coil winding, and having an electric connector device, by way of which the at least one magnet coil winding is supplied with current, wherein the electric connector device has at least one pin-shaped electric connector body which is connected via a releasable electric connection to at least one current-conducting electric cable which is guided from the outside to the at least one pin-shaped connector body in relation to the brake magnet. The at least one pin-shaped electric connector body may be arranged on a free and outer surface of the magnet coil body or an element which is connected to the magnet coil body.

  • Patent number: 7806242
    Abstract: A magnetic rail brake device of a rail vehicle comprises at least one braking magnet including a magnet coil body having a plurality of magnetic elements held thereon, and which magnetic elements are movable. The device also comprises at least one fixing strip running parallel to a longitudinal length of the magnetic coil body and directly connected to the magnetic coil body to fix the braking magnet to other components of the magnetic rail brake device.

  • Patent number: 6953107
    Abstract: The disclosure relates to a magnet track braking device comprising a magnetic base and/or support body and a pole shoe section containing a magnetic flow guiding area and a magnetic flow separating area. The disclosure is characterized in that the magnetic base and/or support body is made from materials having different magnetic characteristics, so that an increase in induction in the gap between the magnet track brake and the rail head is reduced when erosion occurs in the pole shoe section.
