Definitions

  • the present invention relates to a device for axial and torsional retention of a tubular body mounted to slide in a sleeve, in particular for a shock pad, the sliding of said body having to be able to take place axially within certain limits, this device comprising at least one external key.
  • axially elongated consisting of a head mounted in a housing of said sleeve, and of a heel engaged in an axial lumen of said body, without notably protruding inside the latter.
  • shock buffer is intended to denote in particular the devices which, on railway vehicles, namely wagons and power cars, serve to absorb shocks between vehicles. It is known that in these devices the damping is produced by an elastic system compressed between the bottom of the sleeve, which is usually secured to the vehicle, and the front face of the pad, which constitutes a bottom for said tubular body.
  • Said elastic system is commonly constituted, for example, by a stack of plates which are free to slide in the tubular body and between which are blocks of rubber or elastomer.
  • German patent n ° 447 842 a retaining device of the type mentioned at the beginning is known, in which the axially elongated outer key has at one end a tab, which is tightened, by a screw and nut fixing system, against a collar of the sleeve.
  • the key thus has no degree of freedom, and its fixing system is permanently subjected to forces, due to the thrust constantly exerted on the heel of the key by the outer end flange of the cooperating tubular body. This can result, at said tab of the key, significant efforts and fatigue, and premature decommissioning by wear or breakage of the metal.
  • the assembly and disassembly of the key is relatively difficult.
  • an axial and torsional retaining device of the general type defined at the start is, in accordance with the invention, characterized in that the head of the key is mounted in the housing of said sleeve by means of two transverse axes serving as pins and engaged in its ends and in holes in the side walls or cheeks of said housing, the key being able to pivot around one of these axes during the mounting of said tubular body in the sleeve and in what is provided a clearance between said transverse axes and the head of the key, and / or between these same axes and the holes of said cheeks, this clearance being axial, namely that '' it allows a slight movement of the key in the direction of said axial lumen of the tubular body, this movement, caused by a relaxation of said elastic system, which can be stopped by abutment of the key head on the corresponding end of said housing of the sleeve.
  • the effort of relaxation of the elastic system after cessation of a compression due to a shock on the tampon, effort which can be very important, will be exerted on the key without passing in a notable way by its transverse axes restraint; the key will be subjected to a compressive force exerted between the front face of its heel, in contact with the corresponding end of the axial lumen of the sliding body, and the opposite end of its head, bearing against the corresponding end sleeve housing.
  • this front face of the heel of the key is inclined towards the bottom of the sleeve and in the direction of the axis of the latter.
  • a device according to the invention may comprise several, for example two diametrically opposite, or, if necessary, a larger number, preferably evenly distributed around the periphery of the sleeve.
  • This tubular body 5 is retained in the sleeve 1 by means of two diametrically opposite keys 6. Since these two keys and the associated means are identical, only one will be described below.
  • the key has a head 6a by which it is mounted in a housing 7 of the sleeve 1, by means of two pins 8 and 9, as well as a heel 6b, which is engaged in an axial slot 10 of the tubular body 5.
  • Said housing 7 of the sleeve is delimited by two lateral cheeks 11, pierced with holes 12 receiving the ends of the axes 8 and 9, and by two abutment surfaces 13 and 14 for the key head 6a (FIG. 3).
  • front 16 and rear 17 faces of the heel 6b of the key faces which are semi-cylindrical, are inclined towards the bottom 3 of the sleeve 1 and towards the axis of the latter, the front face 16 being intended to cooperate with the end 18, correspondingly inclined, of the axial lumen 10 of the tubular body 5.
  • the mounting of the key 6 will then be completed by positioning of the axis 9 in the corresponding holes 12 and 15, after which the prestressing force can be released and the device will be ready to start operating, the tubular body 5 being retained in the sleeve 1, against the detent force permanently exerted by the system 2, by abutment of the end 18 of the axial light 10 on the inclined front face 16 of the heel 6b.
  • the axis 9 will be removed and the key 6 will be pivoted outwards, after having axially compressed said elastic system 2, with a force greater than that of the prestressing, that is to say sufficient for that the front face 16 of the heel 6b of the wedge can come out of contact with the end 18 of the lumen 10 and the heel 6 can thus be extracted therefrom. Thereafter, of course, the tubular body 5, with its elastic system 2, can be entirely removed from the sleeve 1.
