  • Patent number: 5979610
    Abstract: A rail brake device (1) having permanent magnetic energization, comprising a housing (3) of magnetizable material, which housing is mounted for up and down movement and has at least one permanent magnetic element (5) which in an operating position of the rail brake device is magnetically coupled to a rail (2), wherein the magnetic element is fixedly mounted along a first wall of a cavity in the housing; a switching element (16) of magnetizable material, slidable back and forth, is located next to the magnetic element, and a second wall of the cavity comprises two parts separated by a magnetic barrier (11), wherein, in the rest position, the switching element forms a magnetic connection between the magnetic element and a part of the second wall (19) of the cavity which is in direct connection with a side of the magnetic element facing away from the switching element, while in the operating position, the switching clement forms a magnetic connection between the permanent magnetic element and another part of the

  • Patent number: 5207024
    Abstract: A door system of the swivel-sliding type for use in a vehicle, suitable in particular for a vehicle for public transport, the door system comprising at least one door panel; suspension means for the at least one door panel, which comprise a telescopic guide; and a drive system for the at least one door panel, wherein the drive system comprises at least one piston-cylinder assembly of which a first movable part is connected to the telescopic guide via a system of arms and rods so as to cause the telescopic guide in operation to perform a plugging movement, while a second part of the piston-cylinder assembly is provided with a projection extending into a track having a first section extending substantially transverse to the at least one door panel and an adjoining section extending substantially parallel to the telescopic guide, the projection forming a part of a pantograph construction mounted between a fixed pivot point and a point of attachment on the door panel, said pantograph construction transmitting the

  • Patent number: 5018605
    Abstract: 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.
