Definitions

  • the invention relates to an arrangement for the transverse suspension of block brake units for rail vehicles on the vehicle or bogie frame by means of two laterally oscillating hanging brackets and for support in the longitudinal direction of the frame by means of upper and lower pressure or tension members.
  • the two mutually parallel suspension brackets are arranged between the vehicle or bogie frame and the upper end of the block brake unit, connected to the frame by an upper cross bolt and to the block brake unit by a lower cross bolt, and to the respective upper end on the upper cross bolt and to the respective one lower end rotatable on the lower cross bolt, laterally displaceable and laterally movable.
  • Each hanging bracket is connected between its two ends on the side facing the wheel to be braked by a tension member formed by two shackles with the vehicle or bogie frame.
  • the block brake unit is connected to the frame by two push rods or, in the case of a double-sided braked wheel, by two tie rods to the lower end of the brake block suspension on the other wheel side (DE 38 16 157 C2).
  • the invention has for its object to provide an arrangement of the type mentioned, which requires little space above the block brake unit with a simple and inexpensive construction and reliable operation and practically does not give rise to lateral forces dependent on the direction of travel.
  • the block brake unit 1 is assigned to a wheel 2 of a rail vehicle, which rolls on a rail 3, has a wheel flange 4 and belongs to a wheel set which is arranged in the vehicle or bogie frame 5 so as to be capable of transverse movement.
  • the wheel 2 can thus move laterally with respect to the frame 5, i.e. perpendicular to the plane of Fig. 3.
  • the block brake unit 1 interacts with the wheel 2 by means of a brake block holder 8 provided with brake blocks 6, 7 and has a brake cylinder, a transmission gear and a stroke actuator for actuating the brake block holder 8, which can function as shown in DE 41 17 632 A1 and described, and which are housed in a housing 9.
  • the brake pad holder 8 is suspended from the housing 9 by means of a pendulum bracket 10.
  • the block brake unit is suspended transversely on the vehicle or bogie frame 5 by means of two laterally oscillating hanging brackets 11, 12 and is supported in the longitudinal direction of the frame 5 by means of an upper pressure member 13 and two lower pressure members 14, 15 and lower tension members 16.
  • the two hanging brackets 11, 12 are each formed by a transversely elastic leaf spring and extend on both sides of the block brake unit 1 from its upper end 1 a to its lower end 1 b to which they are connected, as well as the two lower pressure members 14, 15 and Tension members 16.
  • the upper end 1a of the block brake unit 1 is connected to the upper pressure member 13 between the two upper ends 11a, 12a of the hanging brackets 11, 12.
  • the two hanging brackets 11, 12 are connected by means of an upper cross bolt 17 which penetrates a transverse bore 18 in the upper end 1 a of the block brake unit 1 with a relatively large amount of play.
  • the upper end 1 a of the block brake unit 1 is designed in the form of a hollow axis and in the middle thereof the upper pressure member 13 is articulated to the end 1 a.
  • the two hanging brackets 11, 12 are connected to one another by means of a cross bolt 19.
  • the sleeve-shaped lower end 1b of the block brake unit 1 is rotatably mounted on the lower cross pin 19.
  • the two lower pressure members 14, 15 and tension members 16 are articulated on the lower transverse bolts 19.
  • the upper cross bolt 17 is received at the two ends in a frame-fixed eye 20 and 21, respectively.
  • the upper ends 11a, 12a of the two hanging brackets 11, 12 are each clamped between an annular shoulder 22 and 23 of the transverse bolt 17 and a nut 24 and 25 screwed onto a threaded section of the same.
  • the lower ends 11b, 12b are also each clamped between an annular shoulder 26 or 27 of the lower transverse bolt 19 and a nut 28 or 29, which is screwed onto the respective end of the transverse bolt 19 provided with an external thread.
  • the upper pressure member 13 and the two lower pressure members 14, 15 are each articulated with the end facing away from the block brake unit 1 to an upper frame-fixed eye 30 and a lower frame-fixed eye 31, respectively.
  • the two lower tension members 16 are provided, which connect the lower end 1b of the pad brake unit 1 and the lower end 32b of the pad block 32.
