Definitions

  • the invention relates to a combined pulling and pushing device with a friction spring and an elastic cartridge for central buffer couplings of rail vehicles, the device being inserted into or replacing the connecting rod connecting the coupling head to the articulation and the elastic cartridge from a tubular body with a piston that can be displaced against the spring medium exists, which is guided out of the elastic cartridge via a piston rod, the elastic cartridge being longitudinally displaceable within a friction spring arranged in a gimbal-mounted housing on the linkage.
  • Friction springs are particularly advantageous because relatively large forces can be cushioned with such devices with relatively small spring travel. Friction springs, however, cannot be used to build shock absorbers that only respond above a certain limit and then absorb the excessive shock and keep the energy that occurs in the event of such impact away from the vehicle. It has therefore been proposed, for example, in DE-PS 19 47 819 a device which is able to absorb oversized impacts. The disadvantage is that this known device must be replaced after every response. This effort is considerable.
  • the present invention is therefore based on the object of avoiding the disadvantages of the known constructions and of using a combination of friction spring elements and elastic cartridges in central buffer couplings, which takes advantage of the two elements without having to accept their disadvantages.
  • the elastic cartridge is connected to the coupling head and is mounted in a rotationally fixed manner in the housing and that the intermediate piece has a stop abutting against the front end of the friction spring and a stop abutting against the carbon rod of the elastic cartridge which is led out to the rear. which also bears against the rear end of the friction spring via a rear intermediate layer and also has a distance from the end stop corresponding to the deflection of the friction spring.
  • the characteristics of the friction spring and the elastic cartridge are advantageously set differently, the response force of the elastic cartridge preferably being greater than the greatest spring force of the friction spring.
  • the intermediate piece expediently consists of a tube piece, onto the front end of which the outwardly projecting stop is screwed, which abuts against the front end of the friction spring via a front intermediate layer.
  • the advantage of the device according to the invention lies above all in the fact that the elastic cartridge also forms an elastic intermediate buffer in the area in which the friction spring fulfills its function, which only comes into effect when the entire path of the friction spring has been cushioned and then can still absorb oversized bumps elastically.
  • the housing 11 for the friction spring 12 is gimbaled on the (not shown) linkage housing and is held in the horizontal plane at the center by known support legs 13, which but can also be replaced by any other known centering device.
  • an elastomer cartridge 14 known per se which is connected at the front end to the coupling head (not shown).
  • An extension piece can also be provided between the elastomer cartridge 14 and the coupling head.
  • a tubular intermediate piece 15 is provided, in which a stop 16 is screwed onto the front end, which protrudes radially outward beyond the intermediate piece 16 and lies against the other end of the friction spring 12 via the front intermediate layer 17.
  • Plastic sliding blocks with a small coefficient of friction are arranged at 18 between the elastomer cartridge 14 and the stop 16, at 19 between the bellows 16 and the friction spring housing 11 and at 20 between the friction spring housing 11 and the front intermediate layer 17, whereby a good displaceability between the three parts is effected relative to one another .
  • a wedge 22 is fastened to the friction spring housing 11 with the screw 23 and is mounted in a longitudinally displaceable manner in a groove 21 in the stop 16. This prevents the intermediate piece 15 from rotating relative to the housing 11.
  • the elastomer cartridge 14 carries a wedge 24, which in a longitudinal slot 25 in Intermediate piece 15 is displaceable. This prevents the elastomer cartridge 14 from rotating relative to the intermediate piece 15. Both measures together prevent the coupling head attached to the elastomer cartridge 14 from rotating relative to the articulation.
  • a stop 26 is screwed in so far that the stop 26 bears against the piston rod 27 of the elastomer cartridge 14 projecting towards the rear and generates a prestress with the collar 34, the piston rod 27 being better guided in a recess 28 engages in the stop 26.
  • a collar or flange 29 projecting outward beyond the intermediate piece lies against the friction spring 12 from behind via the rear intermediate layer 30.
  • the collar 29 can also be part of the stop 26.
  • the intermediate layer 30 is extended to the rear so far that it abuts the end stop 31 and thereby forms the abutment for the friction spring 12. In the normal position, there is a distance R between the end stop 31 and the stop 26, which corresponds to the permissible deflection path of the friction spring 12.
  • Sliders 32 and 33 made of a low-friction plastic are arranged between the rear intermediate layer 30 and the housing 11 on the one hand and the flange 29 on the other hand.
  • the shocks occurring in normal traffic are transmitted from the coupling head to the elastomer cartridge 14, which in turn transmits the shocks via the piston rod 27, the stop 26, the intermediate piece 15, the stop 16 and the intermediate layer 17 to the friction spring 12, which then compresses. If the impact force exceeds the force of the friction spring 12 when the impact is too great, the stop 26 is pushed back so far that it abuts the end stop 31, that is to say has passed the path R. If, as a result of the oversized impact, the elastomer cartridge 14 is pressed even further over the coupling head, the cartridge 14 moves by at most path E, the piston rod 27 being pushed into the cartridge 14 and displacing the plastic there in a known manner. The impact energy is destroyed.
  • the response force of the elastomer cartridge 14 is greater than the greatest force to be exerted by the friction spring 12.
  • the impact energy is destroyed during the penetration of the piston rod 27. This impact energy is therefore kept away from the linkage and thus from the vehicle. If the impact stops, the elastomer cartridge 14 shifts again by the path E within the intermediate piece 15 due to the known properties of the elastomer until the state shown in the drawing is reached again. Since the response force of the elastomer cartridge 14 is strongly dependent on the run-up speed, it may be possible for the strokes of the friction spring 12 and the elastomer cartridge 14 to be superimposed during the axial movement of the coupling head.
  • the elastomer cartridge 14 When pulling on the coupling head, the elastomer cartridge 14 is pulled forward. The tensile force is then transmitted via the collar 34, the intermediate piece 15, the flange 29 and the rear intermediate layer 30 to the friction spring 12, which rests against the collar 35 and compresses. The elastomer cartridge 14 is not used when pulling on the coupling head.
  • the arrangement can also be reversed with the same mode of operation, so that the coupling head is arranged on the friction spring housing 11 and the device with the elastomer cartridge 14 is linked to the vehicle directly or via a linkage housing.
  • the stops 16 and 26 are secured against rotation on the intermediate piece 15 in a manner known per se. All known center reset devices can also be used.
  • the spring medium in the elastic cartridge can be an elastomer, a prestressed gas, a fluid connected to a storage device, or one or more ring or helical springs, divided or undivided.
