Definitions

  • the invention relates to a braking device for rail vehicles according to the preamble of claim 1.
  • the brake linkage of brake devices must be adjusted as automatically as possible with the increasing requirements with regard to permissibility and economy and is usually carried out by means of single-acting or double-acting linkage adjusters (DE-PS 19 46 684).
  • a double-acting slack adjuster can also lengthen and thus adjust the pad clearance changes that occur when loading and unloading the vehicles.
  • the brake linkage must be readjusted in a known manner when maintenance work is required. According to the specified maintenance documents, the time and type of readjustment must be determined by the personnel and the work must be carried out. This necessary work and its monitoring require a lot of effort.
  • US Pat. No. 2,118,389 shows a braking device with two slack adjusters which are acted upon in parallel by a brake cylinder. At least one friction pair is assigned to each slack adjuster via a brake slack chain. Depending on the length of the brake linkage chain provided, or depending on the number of brake pads to be actuated, depending on the wear of the brake pads of the friction pair, there is also a more or less large adjustment path for each linkage adjuster with the same disadvantageous consequences as in the discussion of the DE-PS 19 46 684.
  • the invention has for its object a generic brake device with at least two linkage actuators actuated by a working cylinder, with which longer brake linkage chains can be formed with automatic adjustment of the wear path of the friction pairings and larger inclinations of the brake levers due to wear of the friction pairings can be avoided with regard to compliance with the nominal block play to release the released brake.
  • the braking device with the usual H-brake linkage arrangement has a working cylinder 1 at the beginning of the arrangement, which acts on a linkage adjuster 4 of a known type via an actuating lever 3 supported on the frame 2.
  • the control of the braking device takes place according to the invention with the inclusion of a control stop 5, which is displaceable longitudinally relative to the slack adjuster 4 on the frame 2 at a distance B and which is connected via the link members 5a and 5b to the end joint point 10a of the H-brake linkage 6, 9, 10.
  • the slack adjuster 4 engages via a brake lever 6 on an associated friction pair 7, 8.
  • a coupling rod 9 is articulated on the brake lever 6 and is articulated on a brake lever 10 for a force-counteracting friction pairing 8, 11. At its end facing away from the friction pairing 8, 11, the brake lever 10 engages a further linkage adjuster 12 via a joint 10a.
  • the slack adjuster 12 engages a further brake lever 14 via a joint 14a and a brake lever 16 which counteracts the brake lever 14 via a coupling rod 15, the brake levers 14 and 16 acting on the associated friction pairing 17, 18, 19. At its end facing away from the friction pairing 18, 19, the brake lever 16 is supported on the frame 2 in the bearing 20.
  • the braking device can be continued on the bearing 20 of the brake lever 16 in a continuation of the brake linkage chain by further linkage adjusters and associated brake levers, the control stop 13 then being relatively controlled in the same way as the control stop 5 by a connection to the joint 20.
  • the working cylinder 1 acts on the actuating lever 3 mounted in the frame 2, which acts on the slack adjuster 4 and which in turn is pulled in the direction of the control stop 5 until the friction pairing 7, 8 engages.
  • the brake lever 6 now transmits the force, supported on the friction pair 7, 8, to the coupling rod 9, which transmits the force via the brake lever 10 to the friction pair 11, 8 and, at the same time or after the friction pair 7, 8 has been applied, the slack adjuster 12 in the direction pulls on the tax stop 13.
  • the slack adjuster 12 actuates the brake lever 14 and its associated friction pairing 17, 18 and, via a coupling rod 15, the brake lever 16 and its associated friction pairing 18, 19.
  • the brake lever 16 is supported at its end in the bearing 20 on the frame 2, or when continuing the brake linkage chain on another linkage adjuster.
  • the distance B between the upstream slack adjuster 4 and the control stop 5 associated therewith is the sum of the required play for the friction pairings 7, 8 and 8, 9 arranged between the upstream slack adjuster 4 and the respectively arranged slack adjuster 12 in the ratio of the lever divisions the levers 6 and 10 are similar in size to the paragraph A to be set in a comparable manner between the slack adjuster 12 and the associated control stop 13, taking into account the lever ratios on the brake levers 6, 10, 14 and 16 involved.
  • the distance A is thus determined in a comparable manner when the brake linkage chain is closed without further linkage adjusters solely by the sum of the required play for the associated friction pairings 16, 17 and 17, 18.
  • a brake device shown in Fig. 2 shows a possible embodiment for 3-axis drives with two slack adjusters and symmetrical distribution of the adjustment paths for the slack adjusters 4 and 12 and is identical to the assembly X arranged between the joints 10a and 14a instead of the slack adjuster 12 the braking device shown in Fig. 1.
  • the assembly X has, in addition to the slack adjuster 12 and the control stop 13, further brake linkage parts for actuating additional friction pairings for the third axis.
  • the brake lever 10 engages via the joint 10a on a coupling rod 21 which articulates at the end of a lever 22 supported in the frame 2 at the other end.
  • the lever 22 is connected in an articulated manner between its ends via a coupling rod 23 to a further lever 24, which is also supported in an articulated manner between the ends of the coupling rod 23 and on the one hand at its one end via a coupling rod 25 and a brake lever 26 of a friction pairing 27, 28 is assigned and on the other hand engages at its other end on the slack adjuster 12.
  • the brake lever 26 is articulated between its ends in the frame 2.
  • At the other end of the linkage adjuster 12 is a mirror-symmetrical arrangement of the levers 24 ', 26' and 22 'and the coupling rod 21', 23 'and 25 to the above-described linkage arrangement for the friction pairing 27, 28 to act on the second friction pair 28, 29 for the central axis ' intended.
  • the assembly X is articulated to the brake lever 14 via the joint 14a.
  • the slack adjusters 4 and 12 each regulate the play of three friction pairs, namely the slack adjuster 4 controls the play of the friction pairings 7, 8; 8, 11 and 27, 28 and the slack adjuster 12 the games of the friction pairings 28, 29; 17, 18 and 18, 19.
  • the design of the above-mentioned linkage chain enables the levers 22, 22 'and 24, 24' and the coupling rods 21, in particular in the case of a lateral-horizontal arrangement. 21 ', 23, 23' and 25, 25 'a useful use of the limited space in the bogie.
  • the games for the friction pairings add up in the same way as in the example shown in FIG. 1, so that the distances A and B can be determined in a comparable manner.
  • the brake linkage arrangement acc. 1 and 2 can be formed in pairs for actuating the friction pairings on both sides of a wheel set and can be applied via generally known brake triangles.
  • All slack adjusters used in the row arrangement can be single-acting or double-acting.
