Definitions

  • the invention relates to an automatic pull coupling for rail buffers carrying side shock buffers, the coupling head protruding in front of the buffer plane in the uncoupled state and being displaceable against a spring force.
  • US Pat. No. 968,495 shows a bearing piece located in front of a buffer screed, to which an automatic coupling can be articulated.
  • This bearing piece engages with two arms on both sides, two-armed levers that are rotatably supported in the middle in horizontal planes on the buffer beam.
  • each lever overlaps a stop-like extension of the spring plate of a side shock buffer, such that when the bearing piece is pulled forward, the spring plates of the shock buffer are pushed back by turning the lever. This results in a cushioning of the forward stroke movements of the bearing piece or the coupling articulated to it by compression of the shock buffers.
  • a return stroke suspension of the bearing piece is not provided.
  • the reduction gear can be constructed very easily; the spring of a shock buffer is used for the return stroke suspension; there is therefore no need for a separate, expensive spring arrangement for the pull coupling.
  • the buffer capacity of the shock buffers is retained at the coupling points of neighboring vehicles, it is only stretched over a longer stroke, so that the spring characteristic after the engagement of the automatic pull couplings until the shock buffers touch each other is flatter than the characteristic of the shock buffers among themselves, i.e. after their mutual investment.
  • the buffer screed of a rail vehicle (not shown in the rest) is protruded forward in its central region by the coupling head 2 of an automatic coupling.
  • the tension coupling head 2 is mounted in a suitable manner, for example on a guide 3, so that it can be moved back.
  • the buffer board 1 carries a shock buffer 4a or 4b on each side.
  • the spring plates 5 of the two shock buffers 4a and 4b define a buffer level 6, which is at the usual distance in front of the buffer board 1.
  • the coupling center of the coupling head 2 determines the position of a coupling plane 7, which is in the uncoupled, free state of the coupling devices at a distance h from the buffer plane 6.
  • the coupling head 2 has near its rear end, just in front of the buffer beam 1, as a coupling point 8 for coupling one end of a two-armed lever 9 to a bearing pan 10 with side walls raised in the manner of a stop.
  • the lever 9 is rotatably articulated on a bearing block 11 of the buffer beam 1 in a horizontal plane. With its second end, the lever 9 engages behind one end of a second, two-armed lever 12; the contact point of the two levers 9 and 12 is designed to be liftable in the manner of a stop coupling 13.
  • the lever arm 14 of the lever 9 facing the pull coupling head 2 is substantially longer than the lever arm 15 facing the lever 12, the length of the lever arm 14 can be a multiple of the length of the lever arm 15.
  • the lever 12 is also rotatably mounted approximately centrally on a bearing block 16 of the buffer beam in a horizontal plane.
  • the end of the lever 12 facing away from the lever 9 is connected in an articulated manner to the spring plate 5 of the shock buffer 4a via a tension member 17, which extends approximately in the longitudinal direction of the rail vehicle.
  • the two levers 9 and 12 thus represent a reduction gear which transmits return stroke movements of the coupling head 2 in accordance with the length ratio of the two lever arms 14 and 15 as significantly smaller return stroke movements to the spring plate 5.
  • shock bumpers diametrically opposed to each other are to be coupled to the drawbar coupling head assigned to the respective vehicle end via a reduction gear.
  • the coupling head 2 is by the measure pressed behind the buffer level 6 before the spring plate 5 of both vehicles come to the system.
  • shock buffers 4a and 4b As usual, further shock loads are absorbed by shock buffers 4a and 4b. With this further deflection of the shock buffer 4a, the tension member 17 can turn the lever 12 further while opening the stop coupling 13, the tension coupling head 2 is thus pushed back only by the counter-tension coupling head.
  • the tension member 17 can only transmit tensile forces, that is to say, for example, be designed as a chain, rope or the like.
  • the lifting coupling 13 can then be replaced by a coupling that provides constant engagement of the two lever ends.
  • the reduction gear shown in the drawing comprising the two levers 9 and 12
  • the one-armed lever is to be rotatably supported near the shock buffer 4a on the buffer beam 1 in a horizontal plane, the tension member 17 is to be articulated near the bearing point on the one-armed lever and the other end of the lever is to be stored in the bearing pan 10.
  • a large reduction ratio can be achieved, as may be desired for reducing the high spring preload of the shock buffer 4a into the relatively low, only a safe coupling of the coupling coupling to ensure dimensioning the driving coupling head 2.
