Definitions

  • the invention relates to a magnetic rail brake, in which both a brake magnet unit in front and a brake magnet unit are arranged behind the wheel of a rail vehicle.
  • Conventional magnetic rail brakes for rail vehicles with two-axle drives in which the axles are mounted in pairs on a bogie that can be rotated about a vertical axis, are implemented in such a way that a brake magnet unit can be lowered or raised between the wheels of the two axles for each rail.
  • the object of the invention is to expand the possible uses of magnetic rail brakes for rail vehicles.
  • this is achieved in that the two brake magnet units are attached to a common brake frame and can be lowered or raised together with it.
  • a magnetic rail brake according to the invention is attached to each of the wheels of the two axes in a rail vehicle with a two-axle drive, in which the two axles are mounted on a common bogie, then the braking force increases to almost twice the value compared to a conventional magnetic rail brake.
  • the two magnetic rail brakes arranged on the opposite sides of an axle can be attached to a common brake frame, so that when this frame is lowered, the brake magnet units of the two magnetic rail brakes be pressed onto the two rails simultaneously.
  • An important advantage of a magnetic rail brake according to the invention is that it can not only be used in a two-axis drive, but can also be used in rail vehicles with single-axis drives. Until now, the use of commercially available magnetic rail brakes was not possible with these. Even with a reduced version of a conventional magnetic rail brake, there are space problems or difficulties in achieving sufficient stability.
  • the brake frame can be steered by drivers attached to the chassis frame or by drivers attached to the wheelset bearing or to a part connected to it.
  • a magnetic rail brake (with permanent magnets) according to the invention can also be used as a hand brake.
  • the brake frame is lowered pneumatically.
  • FIG. 1 shows a conventional magnetic rail brake for a two-axis drive, in which the two axes 1, 1 'are mounted on a bogie 2 which can be rotated about a vertical axis.
  • a brake magnet unit 3 is attached between the two wheels 4, 4 'of the two axles 1, 1' so that it can be lowered or raised.
  • the brake magnet unit 3 is lowered or raised via the pneumatic or hydraulic pistons 5, 5 'which are attached to a bogie 2, the brake magnet unit 3 being guided in the longitudinal and transverse directions by guide elements 6, 6'.
  • the attachment of magnetic rail brakes according to the invention to a two-axle drive on the two wheels 4, 4 'of the two axles 1, 1', which are mounted on the bogie 2, is shown in FIG. 2.
  • the magnetic rail brakes according to the invention each include two brake magnet units 3, 3 'in front of and behind each of the two wheels 1, 1', the two brake magnet units 3, 3 'being attached to a common brake frame 7 and being able to be lowered or raised together therewith.
  • the lowering or raising of the brake magnet units 3, 3 'or the brake frame 7 is carried out in an analogous manner as before by means of the hydraulic or pneumatic cylinders 5, 5 ', which can be attached to the bogie 2 or to the car body.
  • the brake magnet units 3, 3 ' are guided in the longitudinal and transverse directions by drivers 8, 8' fastened to the bogie and guide elements 9, 9 'fastened to the brake magnet units 3, 3' or are steered with the bogie.
  • the main advantage of the magnetic rail brake according to the invention in this case is an increase in the braking force compared to the conventional magnetic rail brake shown in FIG. 1 to almost twice the value.
  • a magnetic rail brake according to the invention can also be used in single-axis drives, as shown in FIG. 3.
  • a steering of the brake frame 17 or 17 ' is provided so that the brake magnet units 3, 3' also when cornering on a curved track, lie vertically above the rail.
  • 4a shows a non-steered brake frame 17 for comparison, in which the brake magnet units 3, 3 'are not perpendicular to the rails 20, 20' when cornering over a track curve. If, on the other hand, the brake frame 17 is steered with the axle 1, as shown in FIG. 4b, such unfavorable behavior does not occur and the brake magnet units 3, 3 'are always vertically above the rails 20, 20'.
  • the brake frame 17 or 17 'of the magnetic rail brake shown in FIG. 3 is steered either by the drivers 18, 18' attached to the chassis frame 12 or by the drivers 22, 22 'attached to the wheelset bearing 15 or to parts connected therewith.
  • FIG. 5 shows a highly schematic exemplary embodiment of drivers 22, 22 ′ attached to the wheelset bearing 15.
  • the drivers 22, 22 'designed as L-shaped rails interact with L-shaped guide elements 20, 20' attached to the brake frame 7, there being a play between the drivers 22, 22 'and the guide elements 20, 20'.
  • analog L-shaped drivers are attached to the wheelset bearing on the opposite side of the axle 1, which cooperate with analog L-shaped guide elements on the brake frame 7, which in this embodiment carries the two brake magnet units on both sides of the axle 1 together, the brake frame 7 guided in the longitudinal and transverse directions and steered when the axis 1 is deflected.
  • the functions of guidance and steering can be separate and can be brought about by separate devices.
  • the brake frame can also be lowered in another way, for example hydraulically or mechanically.
