Definitions

  • the invention relates to a magnetic rail brake device of a rail vehicle comprising at least one brake magnet with a magnet coil body carrying at least one solenoid coil and with a yoke and with cheeks protruding therefrom, at the ends pointing to a vehicle rail pole shoes are formed, wherein the at least one magnetic coil the yoke vertically embraces a top pull and with a arranged between the cheeks beam, according to the preamble of claim 1.
  • Such a magnetic rail brake device is for example from the DE 101 11 685 A1 or off FR 1 003 173 A known.
  • the force-generating main component of an electric magnetic rail brake is the brake magnet. It is, in principle, an electromagnet consisting of a magnet coil extending in the rail direction and carried by a magnet coil body and a horseshoe-like magnetic core forming the base or carrier body. The horseshoe-shaped magnetic core forms pole shoes on its side facing the vehicle rail.
  • the DC current flowing in the solenoid causes a magnetic voltage which generates in the magnetic core a magnetic flux which shorts across the rail head as soon as the brake magnet with its pole pieces on the rail rests. This results in a magnetic attraction between brake magnet and rail.
  • the magnetic rail brake Due to the kinetic energy of the moving rail vehicle, the magnetic rail brake is pulled over drivers along the rail. This results from the sliding friction between the brake magnet and rail in conjunction with the magnetic attraction a braking force. The frictional contact with the rail causes fretting wear on the pole shoes of the brake magnet, which must not exceed a maximum amount of wear, since otherwise the magnet coil body is damaged.
  • a single magnetic coil is present, which engages vertically around the yoke of the magnetic core with a top pull and with a arranged between the cheeks beam.
  • the cross section of the magnetic coil is geometrically identical in the region of the upper tension and in the area of the lower tension.
  • the brake magnet is a rigid magnet, to which two magnetic pole shoes are bolted, which are separated by a non-magnetic strip in the longitudinal direction. This serves to avoid a magnetic short circuit within the brake magnet.
  • the pole pieces are formed on the vehicle rail facing end surfaces of the side walls. Rigid magnets are mostly used in local traffic in trams and light rail vehicles.
  • link magnets are known in which the magnetic coil body has no steel core, but only partitions. In the chambers between the partitions magnet members are kept limited movable, which align themselves during the braking operation to better track bumps on the rail head can. In this case, the pole pieces are formed on the end faces of the magnet members facing the rail. Link magnets are used as standard in the full-track area.
  • the magnitude of the braking force of a magnetic rail brake is u.a. from the magnetic resistance of the magnetic circuit, i. the geometry and permeability, the magnetic flux, the coefficient of friction between the brake magnet and rail and the track condition dependent.
  • a significant factor in this case are the magnetic losses, which depend significantly on the geometric design of the magnetic cross section. Against the background of an increasingly limited space in the chassis of rail vehicles, especially in the vertical direction, a low overall height is still required.
  • the object of the invention is therefore to develop a magnetic rail brake device of the type mentioned in such a way that it has a lower overall height with high magnetic force.
  • the coil winding consisting of the turns of the winding wires, as they are wound onto the magnet coil body.
  • This wound on the magnet coil body coil or coil has in a plane perpendicular to the longitudinal extent of the brake magnet (parallel to the rail) seen a certain cross-section, which in addition to the number of turns, the winding density and the wire diameter and the geometry of the magnet coil body, ie of the the coil winding space provided.
  • the invention distinguishes between a top pull of the magnetic coil, which is located above a yoke with respect to the rail, and a lower pull, which is arranged below the yoke.
  • the extension of the rigid magnet or the link magnets should be understood to be parallel to the vehicle rail.
  • the cross-section of the at least one magnetic coil in the upper strip has a lower height and a greater width than the cross section in the beam, wherein the height of the cross section of the magnetic coil is measured in parallel and the width of the cross section of the magnetic coil transverse to a vertical center axis of the brake magnet ,
  • the height of the cross section in the region of the upper which compared to the prior art advantageously leads to a reduction in the height of the brake magnet in contrast, the same magnetic force.
  • a greater height of the cross-section of the magnet coil may be permitted in the area of the substructure without causing disadvantages in terms of the height of the brake magnet, because there the cheeks or the pole shoes of the magnet core can not be arbitrarily shortened due to a required minimum wear height.
  • a relatively high-build brake magnet to achieve a predetermined braking force, this can now build lower with the invention.
  • the number of superposed layers of coil wire windings of the magnetic coil in the region of the upper strip is smaller than in the region of the lower layer.
  • cross section of the magnetic coil in the upper train is substantially rectangular with the longer side perpendicular to the vertical center axis of the brake magnet and in the beam is formed substantially square.
  • the cross-sectional areas of the magnetic coil in the upper strip and in the lower layer are preferably substantially the same size.
  • the brake magnet may be a link magnet, with at least one magnetic coil body on which a plurality of magnetic magnetic members are movably held, or else a rigid magnet.
  • Magnetic rail brake 4 of the prior art instead of a single rigid magnet, a plurality of magnetic members 6 are present, which are held on a movable in the longitudinal direction of the rail 1 extending magnetic coil body 8 limited.
  • This is preferably achieved by virtue of the fact that the magnetic members 6 are suspended tiltably or pivotably suspended symmetrically with respect to a vertical center plane at the side faces of the magnet coil body 8 facing away from one another in chambers formed between partition walls 10.
  • the transmission of the braking forces on the magnetic coil body 8 is then via the partitions 10 and end pieces 14, 15 which are rigidly connected to the magnetic coil body 8 and give the brake magnet 2 via switches and rail joints a good guide.
  • connection device 26 having at least two electrical connections 22, 24 for the positive or negative pole of a voltage source, which are approximately centered, for example, in the upper region of a side surface of the magnet coil body 8, relative to its longitudinal extension is arranged.
  • the electrical connections 22, 24 preferably point away from one another and extend in the longitudinal direction of the magnet coil body 8.
  • FIG. 1 and Fig.2 which show a magnetic rail brake 4 with only one magnetic coil body 8 and only one magnetic coil 9, is in Figure 3 a cross section of a brake magnet 2 shown as a link magnet, in which at least two seen in the longitudinal direction of the brake magnet 2 parallel to each other and in a plane perpendicular to the longitudinal direction seen side by side arranged magnetic coil body 8a, 8b are provided with separate magnetic coils 9a, 9b.
  • the magnetic coils 9a, 9b wound on the magnet coil bodies 8a, 8b can be connected separately, in series or be connected in parallel to each other, that is, that the magnetic coil body 9a associated with the one magnetic coil body 8a may be connected in series or in parallel with respect to the magnetic coil 9b associated with the other magnetic coil body 8b.
  • the central axes 34, 36 of the two magnetic coil body 8a, 8b are arranged with respect to a vertical center axis 38 of the brake magnet 2 at an acute angle ⁇ and converge to the rail 1, ie downwards , Furthermore, the two magnet coil body 8a, 8b are arranged symmetrically with respect to the vertical center axis 38 of the brake magnet 2.

  • Figure 4 shows the cross section of a rigid magnet 2 as a brake magnet, in which the magnetic core 6 is preferably also in two parts and consists of two rigidly connected Magnetkemhcardn 6a, 6b.
