Definitions

  • This invention relates to a railway vehicle. More particularly, this invention relates to a coupling for the undercarriages of a railway vehicle.
  • the invention provides a railway vehicle with a coupling for a pair of undercarriages or trucks supporting the car body of the vehicle which is secured to the undercarriages to reduce the angle of approach of the leading axles of the undercarriages and the guiding forces acting thereon.
  • the coupling includes a transverse link which is installed at a location adjacent to the interior end of each undercarriage, i.e., the end facing the opposite undercarriage, and which is connected with the undercarriage to follow the transverse movements of the car body relative to the undercarriage.
  • a pair of levers are suitably mounted on vertically disposed pivot pins depending from the car body and are arranged symmetrically on opposite sides of the longitudinal axis of the car body.
  • Each lever of each lever pair is articulated to an end of a respective transverse link so as to pivot about the respective pivot pin upon transverse movement of the transverse link articulated thereto.
  • the coupling also includes a pair of tension elements which are disposed longitudinally of the car body in symmetry to the longitudinal axis of the car body. Each tension element is connected to the free arms of the levers disposed on the same side of the car body.
  • the parts of the coupling which are stressed only in tension can be made small so that the space required for the installation of the coupling is available with practically all types of railway vehicles.
  • the levers are angle levers and the tension elements are rods.
  • the tension elements and/or transverse links each contain a prestressed elastic or spring element. This allows an elastic transmission of the displacing forces to be obtained as well as a reduction of the forces to a predetermined optimum value, for example, to about one half.

  • FIG. 2 illustrates a view taken on line IIII of FIG. 1;
  • FIG. 3 illustrates a view of a railway car with a modified form of construction according to the invention
  • FIG. 4 illustrates a view taken on line IV-IV of FIG.
  • FIG. 5 illustrates a fragmentary view taken on line V-V ofFlG. 1;
  • FIG. 6 illustrates a view similar to that of FIG. 2 of a further form of construction.
  • a railway car comprises a car body 1 which is connected at longitudinally spaced points by means of pivots 2 to two undercarriages or trucks 3, 4, and is supported upon the trucks 3, 4 in a known manner (not shown).
  • the car body 1 has a floor which is curved downward in an intermediate-part 5 between the trucks 3,4, (FIG. 5).
  • the car body 1 is provided with a coupling device including transverse links 6, 7 adjacent to the ends of the trucks 6, 7 facing each other, i.e., the interior ends.
  • Each link 6, 7, in turn, is connected at the ends to a pair of double arm angle levers 9; which are disposed symmetrimof the longitudinal axis of the car body 1.
  • Each angle lever 8, 8', 9, 9' is pivotally mounted on a vertically disposed pivot pin 10 which is secured in a mount 11 attached to the underside of the floor 5 (FIG. 5).
  • the links 6, 7 are also guided by means of a centrally located vertical pin 12 which is guided in a guide piece 13 which, in turn, is pivotally mounted in a yoke 20 mounted on the inner wheel axle 14 of a corresponding truck 3, 4.
  • each lever 8, 8', 9, 9 are connected in opposed pairs to each other by means of tension elements 15, 15', such as tension rods, which are oriented longitudinally of the car body 1.
  • tension elements 15, 15' is formed of a number of parts including an intermediate or middle piece 16, a pair of elastic elements 17 attached to the respective ends of the middle piece 16 and a pair of end pieces 18 attached to the ends of the elastic elements 17.
  • the middle pieces 16 are each guided in a respective guideway 34 secured intermediately to the floor of the car body 1.
  • Each elastic element 17 is formed of a spring pot 19 fixed at one end to a tension element 15 and containing a cover 22 fixed at the opposite end, a spring plate 23 slidably mounted in the pot 19 between the cover 22 and a shoulder 24 fixed within the pot 19 in spaced relation to the tension element end of the pot 19, and a compression spring 21.
  • the spring 21 is mounted within the pot 19 in prestressed condition between the cover 22 and shoulder 24.
  • Each end piece 18 extends through a cover 22 and a spring plate 23 of an elastic element 17 and has a threaded end onto which a nut 25 is threaded against the spring plate 23 on the opposite side of the spring 19. In this manner, the end piece 18 can only be stressed in tension.
  • a coupling device for the trucks 3, 4 can also be used which includes a pair of one piece tension elements 27, 27 symmetrically arranged relative to the longitudinal axis of the car body 1 in angular relation to each other, and transverse links 31, 32 which have built-in spring elements.
  • the transverse link 31 at one end of the car body 1 includes two elastic elements 17, as above constructed, for transmitting tension forces while the transverse link 32 at the other end of the car body 1 includes two elastic elements 33 for transmitting compression forces.
  • the elastic elements 33 are constructed in similar fashion to the elastic elements '17 except that the link 32 is fixed to an end of the pot 19, the compression spring 21 is disposed between the end wall of the pot l9 and the shoulder 24, and the angle lever 9, 9' is fixed to the spring plate 23 by an end piece 18 which passes through the cover 22.
  • the car body 1 rests on carriages or trucks 41, 42 and is provided with a coupling between these trucks 41, 42.
  • the coupling includes pairs of tension rods 43, 43', 44, 44' which are each provided intermediately thereof with elastic elements 17, as above constructed.
  • the respective rods 43, 43', 44, 44' are pivotally secured at the outer ends to the trucks41, 42 and are pivotally secured at the inner ends to a respective arm of multi-arm levers 45, 45', 46, 46.
  • Each multi-arm lever 45 -46 is pivotally mounted on a pivotpin 10 depending vertically from the car body 1.
  • levers 45, 45' are made as three arm levers and are connected together by a transverse link 48, which is articulated to the middle arms.
  • the remaining arms of the levers 45, 45 are pivotally connected to the ends of respective tension rods 49, 49'.
  • the opposite ends of the tension rods 49, 49' are pivotally connected to the arms of the levers 46,
  • the levers 46, 46' are made as two-arm or angle levers and are also connected together by a transverse link 50 pivotally secured to the remaining arms.
  • transverse links 48, 50 can be provided with suitable elastic elements 17, 31 as above described. Also, it is possible to use other forms of tension elements than tension rods. For example, wire cables and the like can be used for the tension elements.
