Definitions

  • the invention relates to an actuating device for a rail brake the preamble of claim 1, a bogie for a rail vehicle with a such an actuator and a method for moving a Rail brake from a rest position to a braking position and vice versa such an actuator.
  • Rail brakes are generally suspended and designed so that they have a side play of, for example, 2 to 12 mm in magnetic rail brakes enable the braking position to correspond to the center distance and the curve radius maximum coverage between the rail brake and the Allow rail.
  • the rail brake In the high or rest position, the rail brake is at a high suspension without play.
  • CH 372 337 shows a rail brake device in which the friction body when actuated a braking device is pressed onto a rail surface by means of compressed air become.
  • These friction bodies are fastened in a carrier with which they hold the brake pad form, which is articulated on two piston rods each at the end.
  • the two pistons are axially displaceable in a compressed air cylinder. Become Compressed air is applied to the cylinder, so the brake block is against the rail surface pressed.
  • the cylinders are vented and two tension springs tensioned during braking between the bogie frame and the Carriers pull the brake pads back from the rail.
  • a rail brake is described in German Offenlegungsschrift DE 19 03 315, which can be lowered onto the rail due to its own weight and itself by the forces caused by magnetic induction during operation presses against the rail.
  • the rail brake is lifted off the rail after its actuation by a suspension device with two bellows bodies, the two vertically one above the other and by an elastic ring bead have tightly connected plates, one of which is connected to the frame of the Vehicle and its other rigidly connected to a rail brake magnet is.
  • the rail brake magnet is opposed to the Force of a spring lowered by pressurizing bellows bodies.
  • the object of the invention is therefore a novel actuator for bogies specify that takes up little space and especially the installation a rail brake in high suspension in a motor bogie in connection with Wheel disc brakes allowed.
  • a generic actuating device for a rail brake with at least one actuating element comprises a spring device which holds the rail brake in the first position, which is the rest position of the rail brake in a high suspension, below a predetermined one Minimum distance to the top edge of the rail holds.
  • the actuating device is precise on each bogie side an actuating element, which in a preferred embodiment is an actuating cylinder is provided per rail brake.
  • the spring device comprises preferably two separate springs per rail brake and bogie side.
  • a centering device on the bogie frame and on the rail brake provided the centering device on the rail brake being preferred comprises a centering cone which engages in the centering provided on the bogie.
  • the actuating element preferably also comprises an actuating element centering device, so that the actuating element is kept free of play in the high position becomes.
  • the actuating element centering device in this case comprises a spring element, against which the piston of the actuating cylinder is pressed. To both the actuator as well as keeping the rail brake in the high position without play provided that the various centering devices are all arranged at the same height are.
  • the actuators are preferably located in a motor bogie Rail vehicle use, the motor bogie in a special Embodiment includes a wheel disc brake.
  • the invention also provides a method for installing a rail brake from a rest position in a high suspension to a braking position an actuator according to the invention available, after venting the actuating cylinder the rail brake against the force of the spring device is brought into the braking position and the centering device from the Centering moves, so that the rail brake in its braking position within Games can move. Furthermore, the invention also provides a method for Moving a rail brake from a braking position to a rest position in High suspension with an actuating device according to the invention, wherein the Actuating cylinders are vented and the rail brake with the force of the spring device is brought into the rest position. This will make the rail brake pressed into the centering and held in the high position without play.
  • Figure 1 shows a bogie 1, for example by means of air springs 3 opposite the vehicle frame 5 is cushioned with an actuating device 10, comprising two actuating cylinders 12, 14 according to the prior art, and in Comparison to an actuating device 20 according to the invention the bogie 1 comprises a wheel disc brake housed in the bogie 1 30 with wheel brake caliper unit 32.
  • the rail brake 40 is in the high position. shown in the rest position.
  • the rail brake 40 is a magnetic rail brake with a Plurality of link magnets 42 shown.
  • Regarding the design of the magnetic rail brake 40 and their arrangement in the bogie and their operation according to the prior art with the two actuating cylinders 12, 14 is on the device description "Electromagnetic rail brakes" B-D000.21 the Knorr brake. Brakes for rail vehicles Kunststoff. referred to their disclosure content fully included in this application becomes.
  • the new actuating device 20 according to the invention comprises that shown in FIG Embodiment an actuating cylinder 22 and two springs 24, 26th
  • the compact and thus space-saving design can be clearly seen in FIG the actuating device 20 according to the invention from actuator 10 known in the art.
  • the actuating device according to the invention is again detailed in FIGS. 2 and 3 shown and that in Figure 2 in the so-called rest position or high suspension and in Figure 3 in the braking position.
  • the actuating device comprises 20 for the rail brake 40 an actuating cylinder 22 and springs 24, 26.
  • the rail brake 40 In the rest position, the rail brake 40 is at a height H above the top edge of the rail 50. Because of the large distance wipe the top edge of the rail and the rail brake has no braking effect in this position.
  • centering devices 70 for the rail brake 40 are also present shown from a receptacle 72 and a centering cone 74 .
  • the centering cone 74 is attached to the rail brake 40.
  • the centering device 70 serves to keep the rail brake free of play in the high position shown in FIG becomes.
  • 6a ensure that the actuating cylinder 22 is supported without play and 6b spring elements shown in more detail.
  • the magnetic rail brake is due to the spring force F of the two springs 24, 26th in the high position shown in Figure 2 below the minimum distance H compared to Rail top edge 50 held.
  • FIG. 3 shows a rail brake according to FIG. 2 with an inventive one Actuator shown in braking position.
  • the same components as in Figure 2 have the same reference numbers.
  • the piston 23 of the actuating cylinder 22 presses the magnetic rail brake into the braking position.
  • the centering cone moves 74 from the centering with centering opening 72 and the springs 24, 26 are tensioned.
  • the rail brake 20 can now move in the braking position within its games S 1 and S 2 .
