Definitions

  • the invention relates to a mounting arrangement for transversely movable brake block units on rail vehicles with transversely displaceable wheel sets, with double-walled mounting levers, the two lever arms arranged parallel to one another, firmly connected to one another by at least one web, pivotable at one end on the vehicle frame and pivotable at their other ends at least near the top End are hinged to the brake block unit.
  • a mounting arrangement for a brake caliper unit of a wheel disc brake which essentially corresponds to the above-mentioned features is known from DE-GM 6 751 080.
  • a double-walled mounting lever is provided, the articulations of which are designed with axes of rotation extending horizontally and parallel to the longitudinal direction of the rail vehicle.
  • a torque support for receiving a force component resulting from a brake pad pressing force
  • the torque support can be designed in the manner of a pendulum support to an abutment fixed to the vehicle frame or, with respect to the brake pad arrangement on both sides of the vehicle wheel, as a pull rod which leads laterally past the wheel to be braked to the lower end of an application lever, which runs essentially vertically, at its upper end at Vehicle frame is articulated and which is coupled to the brake pad on the other side.
  • a tie rod can be provided which connects two brake block units arranged in mirror image to the vertical longitudinal center plane of the rail vehicle and thus keeps their mutual distance constant even with lateral deflections.
  • the longitudinal direction of the mounting levers is essentially vertical.
  • the bracket levers as provided for the brake block units, a relatively large amount of space is required above the brake block units, but this is often built into other vehicle parts, in particular the frame or car body: accommodating the bracket arrangement can therefore be difficult.
  • lateral forces which depend on the direction of travel and result from the braking torque, in particular in the case of their short design.
  • This object is achieved according to the invention in that two brake levers are provided for each brake block unit, which extend approximately in the longitudinal direction of the vehicle and are offset from one another in the transverse direction of the vehicle, and in that the axes of rotation of the articulations run vertically.
  • FIG. 1 shows a brake pad unit 1 of conventional design, on which a brake pad 3, consisting, as usual, of a brake block holder and brake blocks held thereon, is suspended by means of a pendulum lever 2, which brake pad is attached to the tread of a vehicle wheel to be braked by means of a pressure tappet 4 belonging to the brake block unit 1 5 can be pressed.
  • the brake pad unit 1 is articulated by means of a pendulum lever 6, which runs essentially horizontally in the longitudinal direction of the vehicle, to an abutment 7 fixed to the vehicle frame; the pendulum lever 6 serves as a torque support for the brake block unit 1, it absorbs part of the reaction force from the contact pressure of the brake block 3 to the vehicle wheel 5 during braking.
  • the brake pad unit 1 On its upper side, the brake pad unit 1 is equipped with two bearing eyes 8, which can also be seen in FIG. 2 and are offset in the transverse direction of the vehicle, for suspension on the vehicle frame which can be rotated about a horizontal transverse axis 9.
  • the brake pad unit 1 with the torque support by the pendulum lever 6 and the transverse axis 9 running through the bearing eyes 8 corresponds to the prior art.
  • Figure 2 only the bearing eyes 8 are shown cut from the brake block unit 1.
  • the bearing eyes 8 are rotatably penetrated by a bolt 10, the axis of the bolt 10 runs coaxially with the transverse axis 9.
  • the bolt 10 is provided with a bearing eye 11 and 11 ', respectively , whose axis 12 intersects the transverse axis 9 at right angles and runs essentially vertically.
  • the bearing eyes 11 and 11 ' ach engage between the two lever cheeks 13 and 14 of two double-cheeked mounting levers 15 and 16, which extend from the bearing eyes 11 and 11' essentially horizontally and in the direction of the vehicle wheel 5 in the vehicle longitudinal direction.
  • the mounting levers 15 and 16 are rotatable on the bearing eyes 11 and 11 'by means of vertical bolts 17 containing the axes 12. articulated; these articulations are illustrated overall by reference numerals 18 and 18 '.
  • the respective upper lever cheek 13 of the mounting levers 15 and 16 rises in the direction of the vehicle wheel 5, the mounting levers 15 and 16 therefore have an increasing vertical extension facing the vehicle wheel and thus a larger base width for their vehicle wheel-side linkage 19 or 19 'on a part 20 fixed to the vehicle frame.
  • the lever cheeks 13 and 14 of each mounting lever 15 or 16 are firmly connected to one another by a vertical lever web 21.
  • the lever cheeks 13 and 14 of the mounting levers 15 and 16 each overlap a bearing eye 22 and 22' on both sides.
  • the two bearing eyes 22 and 22 ' are located at the ends of a fastening part 23 which extends between them and which is fixedly connected to the part 20 by means of two screw connections 24 according to the exemplary embodiment, of which one screw connection 24 is shown with a broken line and the other is only indicated by its axis is.
  • the mounting levers 15 and 16 are each pivotably articulated on the bearing eye 22 and 22' by a vertical bolt 25.
  • the two mounting levers 15 and 16 form a parallelogram-like four-bar linkage, as a result of which the brake block unit 1 is horizontally movable in parallel on the part 20 and thus on the vehicle frame.
  • the brake block unit 1 can thus easily follow lateral displacements of the vehicle wheel 5 with corresponding rotation of the mounting levers 15 and 16.
  • a wheel flange of the vehicle wheels takes the respective brake unit 1 laterally via the brake block 3, this lateral movement is also transmitted via the tie rod to the brake block unit on the other side, so that this also experiences a corresponding lateral displacement .
  • the brake block units 1 on both sides of the rail vehicle are always carried along by the wheel set during its lateral displacements such that the brake blocks 3 of the two brake block units 1 are always in their correct position in front of the treads of the two-sided vehicle wheels 5 of the wheel set.
  • the tread In the case of rail vehicle wheels, the tread is usually tapered towards the outside of the vehicle. If the brake pad 3 is pressed against this conical tread in the direction parallel to the longitudinal direction of the vehicle during braking, it experiences a force component directed towards the vehicle side, a “downhill drive”. To compensate for this force component, it may be expedient to design the mounting arrangement such that, when the wheel set is in the central position, the mounting levers 15 and 16 are inclined towards the vehicle wheel 5 towards the vertical longitudinal plane of the vehicle, namely by an angle which is approximately the cone angle of the Wheel tread corresponds. During braking, the mounting arrangement then exerts a lateral force on the brake pad unit 1 and thus the brake pad 3, which at least approximately compensates for the downward slope of the brake pad 3 and is directed toward the center of the vehicle. When coupling two brake pad units 1 using a tie rod as described above, this results in a particularly favorable, lateral adjustment behavior of the brake pad units 1.
  • the tie rod to be articulated on the bearing eye 26, on the other hand, does not have to be articulated on the corresponding bearing eye of a second brake block unit on the vehicle side, but rather can also be coupled to an axle bearing housing or a transversely displaceable gear housing or another part which displaces transversely with the wheelset. If the above-mentioned slope down force caused by the conical design of the wheel tread with respect to the brake block unit 1 is not or not completely compensated for by a corresponding inclined arrangement of the mounting levers 15 and 16 or in another manner described below, it may be expedient to link the bearing eye 26 Replace tie rods by a component that only transmits tensile forces, for example a rope or a chain.
  • the mounting arrangement according to FIG. 3 largely corresponds to that according to FIG. 2, corresponding reference numbers are entered.
  • the mounting levers 15 and 16 run parallel to the longitudinal direction of the vehicle, and a spring buffer 27 is provided to compensate for the downward slope force described in FIG.
  • the spring buffer 27 has a housing 28 which is arranged on the fastening part 23 on the side facing away from the part 20 with an axial direction 29 running transversely to the rail vehicle is.
  • the housing 28, which has a cylindrical bore 30, is open towards the center of the vehicle; in the bore 30 there is a spring 31 which loads a pressure tappet 32 guided in the bore 30 and projecting beyond the housing 28 in the direction of the center of the vehicle in the direction of displacement towards the center of the vehicle.
  • the vehicle-side mounting lever 16 is provided on its vehicle-side flank with a stop surface 33, on which the pressure tappet 32 rests and is intercepted Center of vehicle.
  • the tension of the spring 31 can be selected such that the downhill force is only compensated for or overcome with an excess of force, in the latter case the brake pad of the brake pad unit is pressed against the wheel flange or the wheel flange root of the assigned vehicle wheel. No tie rod is provided in the embodiment according to FIG. 3, the bearing eye 26 according to FIG. 2 is therefore missing.
  • a spring corresponding to the spring 31 thereof can be provided in another way, acting directly or indirectly in the direction of loading towards the center of the vehicle on the brake pad unit 1.
  • a stop 34 is formed on the fastening part 23 close to the articulation 19 and the part 20, against which a counter-stop 35 arranged on the mounting lever 15 can be placed in a rotational position of this mounting lever 15, which of the respectively provided or corresponds to the predetermined end position of the brake pad unit on the vehicle.
  • the arrangement can be selected such that the stop 34 already engages with the counter stop 35 when the wheel set is in its central position: this can achieve that, based on displacements of the vehicle wheel inside the vehicle, already from the center position of the wheel set, the brake pad no longer constantly bears against the wheel flange of the vehicle wheel and grinds against it.
  • the configuration of the mounting arrangement according to FIG. 4 again largely corresponds to that according to FIG. 2, only the articulations 18 and 18 ', as can clearly be seen from the articulation 18' shown in section, are designed as spherical pivot bearings.
  • the bolt 10 can then be non-rotatably connected to the bearing eyes 8. Otherwise, the embodiment according to FIG. 4 corresponds to that according to FIG. 2.
  • the brake pad unit in any case requires torque support, as shown in FIG. 1 and described above.
  • FIG. 5 is suitable for brake block arrangements with respect to the vehicle wheel 5 on both sides.
  • a brake pad unit 1 On the right side of the vehicle wheel 5 there is a brake pad unit 1, which largely corresponds in its structure and in its mounting on the part 20 to that according to FIG. 1.
  • a pull rod 36 is articulated at the lower end of the brake block unit 1 according to FIG. 5, which crosses the vehicle wheel 5 laterally and is articulated at the other end at the lower end of an application lever 37.
  • the upper end of the application lever 37 is held on the part 20 in the same way as the brake block unit 1; in FIG.
  • the mounting arrangement for transversely movable brake block units (1) is designed as a parallelogram-like 4-link lever mechanism, which is horizontally articulated on the one hand, on the vehicle wheel side, on the vehicle frame (20) and on the other hand on the top of a brake block unit (1) about vertical axes of rotation (12) and has mounting levers (15) extending essentially in the longitudinal direction of the vehicle.
  • the mounting levers (15) can be double-walled with 2 lever cheeks (13, 14) to enlarge their articulation base and stiffening.
  • a torque support is to be provided at the lower end of the brake block unit (1), which acts as a pendulum lever leading to an abutment (7) (6) or can be designed as a pull rod which crosses the vehicle wheel (5) and is coupled to a brake block device on the other side.
  • the mounting levers (15) can be arranged in the pre-installed position inclined by the cone angle or a somewhat larger angle to the longitudinal direction of the vehicle, such that they run approximately at right angles to the wheel tread; With this arrangement, there is at least compensation for the "downhill driving force" acting on the brake pad (3) as a result of the conical wheel tread surface.
  • the mounting arrangement for the brake block unit (1) requires only a small overall height and can therefore be accommodated and mounted on the rail vehicle without being hindered by other components.
