Definitions

  • the invention relates to a buffer for rail vehicles according to the preamble of Claim 1.
  • a buffer for rail vehicles is known in which the Buffer plate provided with a layer of thermosetting, fiber-reinforced plastic is. This layer is connected either by gluing to the buffer plate, or it is provided with metal discs which serve as an abutment for bolts serve.
  • the CH 370 109 is a generic buffer for rail vehicles known, the buffer head to form a shock surface with an inner Part made of plastic and an outer part made of steel.
  • the outer part is provided with a conically widening in the direction of the buffer head bore. In this hole is provided with a corresponding edge inner part held.
  • the outer part is attached to the buffer head with the help of rivets.
  • the buffer head is provided with a circular opening which extends in the direction of the buffer head conically expanded.
  • the opening is in a head part let in, which is fastened by means of rivets on the actual buffer head.
  • the Buffer plate is inserted in this case from the back of the headboard and the headboard then fastened by means of rivets on the buffer head.
  • the opening is inserted directly into the buffer head. In this case is a Provided fastening tool by means of which the buffer plate bent so far will that she can be inserted into the opening. After removing the fastening tool relaxes the buffer plate, causing them in the Opening fixed.
  • the object of the invention is to to develop a buffer formed according to the preamble of claim 1 in such a way that this can be manufactured inexpensively by the buffer plate can be easily and quickly fixed to the buffer head, wherein the butt surface of the buffer plate should have no mounting holes.
  • FIG. 1 shows a buffer designed according to the invention for rail vehicles in the Longitudinal cut. Since generic buffers are basically known, in particular only on the essential features in connection with the invention of the buffer.
  • the buffer has a to be fastened to the rail vehicle Buffer sleeve 1, on which a buffer plunger 2 supported by a spring assembly 3 is.
  • the buffer pusher 2 is on its front side with a round buffer head 4 provided on which a buffer plate 7 is attached, the front of the actual Shock 9 forms.
  • the buffer plate 7 is along its peripheral surface with a groove. 8 Mistake.
  • the buffer head 4 has a round recess 5, in which the buffer plate 7 is included.
  • This recess 5 is of a thin-walled, annular designed edge web 6 limited, which by plastic deformation in Meaning a crimping along the circumference at several points inwardly is bent, that portions 6a arise in the circumferential recess 8 of the Buffer plate 7 engage and fix the latter. Neither in its original Form left edge web 6 nor its inwardly bent portions 6a overhang the front of the buffer plate so that it is a smooth, continuous, having perforation-free abutment surface 9.
  • the edge web is 6 bent inwards at four points 6a uniformly distributed over the circumference, so that alternately in the recess 8 of the buffer plate engaging portions 6a and non-engaging portions 6b are formed.
  • this is preferably provided with a central bore (Not shown), in which a thread is cut, so that the buffer plate can be removed by screwing in a screw.
  • a central bore (Not shown), in which a thread is cut, so that the buffer plate can be removed by screwing in a screw.
  • the inwardly bent part of the edge web -the flanging- in turn bent outwards, leaving the entire edge bridge again assumes its original position.
  • a new buffer plate in the recess of the buffer head are used.
  • the edge bridge will turn in Meaning a crimping on several evenly distributed over the circumference bodies bent inwards.
  • locations of the edge web are selected, which until now have never been plastically deformed, so there is no danger of overuse the material consists of repeated plastic deformation.
  • the buffer plate 50% of the edge web 6 by plastic deformation bent inward
  • the other 50% of the edge web 6 can be used to fix the new buffer plate 7.
  • the buffer plate can be exchanged 3 or 4 times be used without the same area of the edge web 6 more than once must become.
  • the proposed design of the buffer head and the way of fixing the buffer plate has the advantage that the buffer plate can be fixed quickly and easily and their entire front surface is available as an impact surface, since they have no Has mounting holes.
  • the entire buffer can be much cheaper be made because neither the buffer plate nor others, the buffer plate fixing parts must be provided with mounting holes.
  • wear plates with a spheroidally shaped surface is the attachment Of mounting holes associated with relatively high costs.
