Definitions

  • the invention relates to a braking device for rail vehicles, with two brake pads that can be pressed onto diametrical locations on the tread of a vehicle wheel, in accordance with the type specified in the preamble of claim 1.
  • Connecting rods and lever devices designed in this way represent a great outlay in terms of material and production and require a correspondingly large dimensioning of the levers and supporting bolts attached to their ends.
  • connection is not double-cheeked and not carried out on both sides of the vehicle wheel rod, ie if the rod part running outside or inside the vehicle wheel is omitted, the levers attached to the ends of the rod and carrying the brake blocks would be subjected to torsional stresses, which could result in the levers being bent and the articulation points being destroyed.
  • the articulation point of the upper end of the brake lever serving as a vehicle-fixed support the articulation point of the brake pad aligned with the wheel tread and the application force acting on the connecting rod at the lower end of the brake lever are all in one plane, even if the vehicle wheel plane is cutting, none can be on the brake lever Distortion forces occur.
  • a vehicle frame 1 (not shown in more detail) can be seen in FIGS. 1 to 3 ', on which two articulation points 3 are formed for one brake lever 5 and 5' each. In the central area of the brake levers 5, 5 ', a brake pad 7 is articulated.
  • a brake cylinder 9 As shown in Fig. 1, 1 ', the housing of a brake cylinder 9 is rigidly attached in the lower region of the brake lever 5'.
  • a piston rod 11 of the pulling brake cylinder 9 is coupled to one side of an automatic linkage adjuster 13.
  • the other side of the linkage adjuster 13 is articulated via a connecting rod 15 to the lower end of the brake lever 5.
  • Linkage adjuster 13 and connecting rod 15 are guided approximately horizontally past the side of a vehicle wheel 17.
  • the brake lever 5' has an incline crossing the vehicle wheel plane Position up.
  • the lever 5 ' and this also applies to the non-visible, also inclined lever 5 on the other side of the vehicle wheel circumference, is attached to one end of a tubular bearing shell 5 ", which is arranged between two bearing eyes 43 which are fixed to the vehicle wheel center plane 45 and are fixed to the vehicle Articulation point 3 forms.
  • FIGS. 2, 2 ' A second exemplary embodiment of the subject matter of the invention can be seen in FIGS. 2, 2 '.
  • the housing of a brake cylinder 9, which is designed to press here is firmly attached to the brake lever 5 '.
  • a transmission lever 33 is articulated approximately in the center.
  • the piston rod (not shown) of the brake cylinder 9 is articulated.
  • the lower end of the transmission lever 33 which is articulated with its central section on the brake lever 5 ', is connected to a functional part of the adjuster 13 via a linkage point 37.
  • the lower end of one leg of the double leg trained brake lever 5 ' carries a shoulder 35 which ends laterally of the functional part of the linkage adjuster 13.
  • the limiting surface of this extension piece 35 directed towards the adjuster 13 carries a control stop 31 ′.
  • the control stop 31 assumes the distance dimension A proportional to the brake release play to the annular, opposite end face of the adjuster 13.
  • FIGS. 3, 3 ' A further exemplary embodiment can be seen from FIGS. 3, 3 '.
  • the brake cylinder 9 is arranged on the side of the inclined brake lever 5' crossing the vehicle plane and is rigidly and firmly connected to the brake lever 5 '.
  • a transmission lever 39 is aligned parallel to the vehicle wheel plane, with its lower end articulated at the lower end of the brake lever 5 '.
  • the upper end of the transmission lever 39 is articulated to the piston rod (not shown) of the brake cylinder 9, which is directed away from the vehicle wheel.
  • a linkage point for the functional part of the slack adjuster 13 is formed near the middle section of the transmission lever 39, which in turn is connected to the brake lever 5 via the connecting rod 15 (not shown).
  • a control stop 41 is formed on the side of the brake lever 5 ′ facing the linkage adjuster 13, the distance dimension A from the opposite / annular end face of the linkage adjuster 13 being present when the brake is released.
  • the lower end of the inclined brake lever 5 or 5 'crossing the vehicle wheel plane assumes such a position that the connecting rod 15 connecting the lever ends with adjuster 13 can be guided to the side of the vehicle wheel and at a corresponding distance from its outer boundary surface.
  • the articulation point of the brake pads 7 is arranged in all of the designs shown in FIGS. 1 ', 2' and 3 'with preferably a horizontal axis of rotation at the point at which the central portion of the brake lever 5 or 5', the center 45 of the tread 18 of the Vehicle wheel 17 crossed.
  • This design also applies to the double-leg design of the brake lever 5, 5 'shown in FIGS. 2, 2'.
  • the arrangement of the brake cylinder in the last exemplary embodiment is offset laterally with respect to the vehicle wheel center plane.
  • FIG. 3 ' there is an acute angle between the transmission lever 39 and the brake lever 5', ie the application forces are distributed on two planes at an angle to each other.
  • the adjuster 13 is actuated during the release stroke.
  • the piston rod of the pressurized brake cylinder 9 acts on the upper end of the transmission lever 33.
  • the lower end of the transmission lever 33 is pulled via the articulation point located in the middle region of the transmission lever 33 between the two legs of the double-leg brake lever 5' by means of the articulation point 37 via the linkage adjuster 13 and the connecting rod 15, the brake lever 5 located diametrically to the brake lever 5 'and its brake block 7 on the vehicle tread.
  • This pulling movement of the connecting rod 15 to the right can only take place via the brake pad 7 of the brake lever 5 'coming into contact with the vehicle wheel. If the lower end of the brake lever 5 '(articulation point 37) executes a pivot stroke exceeding the distance dimension A, the linkage adjuster 13 is activated in the sense of shortening the connecting rod 15.
  • the adjuster 13 experiences its actuation impulse in the following release stroke in the sense of a shortening of the connecting rod 15.
  • the braking device according to the invention allows a parking brake to be accommodated, for example in the form of a spring-loaded brake cylinder.
