Definitions

  • the invention relates to an extremely short high-performance tie rod for center couplings or center buffer couplings, in particular for rail vehicles, consisting of a hydroelastic element, such as an "oleopatrone", at the front end of which the coupling head with a shell sleeve or the like. is attached, and a friction spring responsive to tensile forces on the coupling head, the rear end of the tie rod being attached to the linkage attached to the vehicle by means of a link pin.
  • a hydroelastic element such as an "oleopatrone”
  • the object of the present invention is therefore to create a pull rod which is relatively very short and yet has all the advantages of the combination of a friction spring and an oleopatrone.
  • One even aimed at being extremely short constructing tie rod also integrate a known mechanical shock absorbing member (DE 19 47 819 C3).
  • a cover bearing is mounted on the housing of the oleopatrone in a rotationally fixed but longitudinally displaceable manner, and a short friction spring is supported on the one hand on the cover bearing and on the other hand via an intermediate tube on the collar of the oleopatrone and the deformation tube of the shock absorbing member, which lies on the intermediate tube is supported at the front on a stop flange of the intermediate tube and cooperates at the rear with the pressure tube of the shock absorbing member supported on the link plate and the tie rod is held together by at least three tie rods that clamp the cover bearing with the pressure tube.
  • the pressure tube of the shock absorbing member is advantageously articulated with a link plate on the link pin of the link housing.
  • the piston emerging from the oleo cartridge is expediently supported on a stop plate, which in turn is supported on a collar in the deformation tube.
  • the advantage of the device according to the invention is above all that the pull rod is on the one hand very short and on the other hand can transmit very large forces, but the excessive pressure or impact forces on the coupling head can be effectively absorbed and prevented by the vehicle itself by means of a shock absorbing member.
  • the tie rod is gimbal-mounted with a link plate 11 on the link pin 12, the pin 12 being mounted in the linkage housing 13 attached to the vehicle.
  • the articulation plate 11 carries a square flange 14, which corresponds to the cover bearing 15, which is also square and lies on the ole cartridge 16.
  • a tie rod 17 which braces these two parts and which is pulled together with nuts 18 in such a way that the tie rod forms a unit.
  • the housing of the oleo cartridge 16 is led out to the front and there carries a shell sleeve 19 with which the coupling head (not shown) is fastened to the pull rod.
  • the pull rod consists of an oleo cartridge 16, on the front of which a cover bearing 15 is rotatably but longitudinally displaceably mounted.
  • a short friction spring 20 is arranged behind the cover bearing 15, which is supported on the one hand on the cover bearing 15 and on the other hand on the intermediate tube 21.
  • the intermediate tube 21 is supported with the inner flange 22 when the device is pulled on the collar 23 of the ole cartridge 16.
  • a collar is provided at the rear end of the deformation tube 26, against which the piston 25 emerging from the ole cartridge 16 bears against the stop plate 24. The distance between the collar 23 of the oleo cartridge 16 and the stop plate 24 gives the stroke that the oleo cartridge can make when pressure is exerted on the coupling head.
  • a support tube 28 is mounted on the intermediate tube 21.
  • the deformation tube 26 is supported forward with the intermediate tube or support tube 28 on the cover bearing 15 and at the rear end the conical pressure surface 29 is arranged with a shear ring, which forms the shock absorbing member with the corresponding pressure surface 29 on the pressure tube 27.
  • the top When using this pull rod, the top is pressed head the oleo cartridge 16 against the force of the piston 25 in the direction of the stop plate 24, whereby the impact energy is consumed. If, however, the energy has not yet been consumed, even though the cartridge 16 is in contact with the stop plate 24 (overload), the intermediate tube 21 with the collar 30 will drive the deformation tube 26 into the pressure tube 27 and expand it with loss of energy by the conical surfaces 29 of the two pipes slide together.
  • the stroke of the shock absorbing member can be determined as required.
  • the cover bearing 15 also slides back over the stroke of the shock absorbing member.
  • the oleo cartridge 16 When pulling on the coupling head, the oleo cartridge 16 takes the intermediate tube 21 over the collar 23, which lies behind the flange 22. The collar 30 of the intermediate tube 21 is placed against the friction spring 20, which in turn is supported on the cover bearing 15. The tensile force is transmitted from the cover bearing 15 via the tie rods 17 to the articulation plate 11 and from there via the articulation 12, 13 into the vehicle. The stroke of the friction spring 20 can be determined as required. If the forces cease, on the one hand the piston 25 is pressed out of the ole cartridge 16 again until it assumes the position shown in FIG. 2, and on the other hand the friction spring 20 relaxes until it again assumes the starting position shown in FIG. 2.
