Definitions

  • the present invention relates to railway and/ or tramway carriages composed oi articulated elements, and an object of the invention is to ccnnect the various articulated elements to each other so as to enable passengers to freely pass from any element to the adjacent element.
  • relative angular displacements in the horizontal plane of two adjacent elements is obtained by means of an articulation cylinder, while an elastic connection (such as, for instance, a rubber connection or small bellows) is provided merely to absorb angular movements due to rolling, rocking, uneven load, rupture of suspension springs, changes in grade, raised rails and imperforations of the track.
  • an elastic connection such as, for instance, a rubber connection or small bellows
  • Figure 1 is a longitudinal sectional view of an articulation according to one embodiment of the invention, when the train elements are in alignment.
  • Fig. 2 is a horizontal section thereof on line X-X of Fig. 1.
  • Figs. 3 and 4 are cross-sectional and plan views of a swing bolster of a truck provided with the articulation.
  • Fig. 5 is a horizontal section similar to that of Fig 2, when the vehicle is on a curve.
  • Fig. 6 is a diagrammatic vertical section on the line Y-Y of Fig. 2.
  • Fig. 7 is a vertical section on the line Z-Z of Fig. 2.
  • Fig. 8 is a vertical longitudinal section of a modification.
  • Fig. 9 The only movement performable by a semicylinder, with respect to the elements A, B bear- Fig. 9 is a horizontal section of said modiiica-l Cil ing the same, therefore, is the rotational movement around ⁇ the pivot.
  • Each semicylinder is xed to the respective element not only by the pivot but-also by top guides shown diagrammatically at I9, 20.
  • the outer surfaces. of the vertical walls and of the ceiling of L1 and ⁇ L2 slide on ribs I5 ofthe vertical walls and ceiling of the elements A and B, while the iioors I6 remain in the seats Il formed in the iioors of saidelements
  • the two semicylinders L1 and L2 are connected to each other and maintained in the respective position as appears in Figs. 2 and 6 by means of a connecting rod 6 with spherical pivots 'I and 8. said connecting rod being located approximately in the plane containing C, parallel to the track plane.
  • the symmetry plane NN (Figs. 2 and 5) of the combination of L1 and L2, owing to a link system 9, 9', 9" (Figs. 2, 5, 7 and 9) jointedly connected to the two elements A and B, constantly coincides approximately with the bisecting plane of the angle formed by the longitudinal center lines of the elements A and B.
  • the articulation provides rotational movements about C of the element A relatively to the element B also in the vertical plane perpendicular to the track.
  • This independency of movement requires a special construction of the truck swing bolster 2 I. Since this single bolster cannot simultaneously follow the movements both of A and B, according to the present invention the swing bolster of the truck having the articulation is provided with four bogie shoes (Fig.
  • Fig. 1 the two pivots 4 and 5 are represented with their axes in vertical alignment with C, (one pivot superposed over the other. Obviously, they f might be replaced by circular guides lying in a same plane parallel to the track.
  • the cylinder L is divided into two parts L1 and L2.
  • the articulation can be constructed, however, without such division, as shown in Figs. 8 and 9, in which casev L is pivotally supported by one of the two elements, for instance A.
  • casev L is pivotally supported by one of the two elements, for instance A.
  • An articulation device for connecting adjacentvehicle elements comprising in combination a transverse frame member, a spherical joint system between said frame member and vehicle elements, said system including a joint member connected to each vehicle element, an openended cylindrical structure disposed between the ends of the vehicle elements and adapted to preserve passageway continuity betweenthesame in their movements of articulation, a pivotal connection in a vertical axis :between said cylindrical structure and said vehicle elements, the axis-of which connection is aligned with 'the center of the spherical joint, a jointed link system connecting the vehicle elements withk capacity for articulation movements in ahorizontal plane, means for guiding articulatory movements Aof the cylindrical structure and vehicle elements in a vertical plane the cylindrical structure being formed in two halves capable of relative articulation in a vertical plane about said spherical joint, said halves being each pivoted to the re- "spective adjacent vehicle element and connected to each other by a horizontal link with universal i,
  • joints substantially in a horizontal plane passing through the spherical joint, and an extensible lmember being disposed between said halves for preserving continuity of the side and top portions of the halvesin their ⁇ articulatory mov'ements.
  • a semi-cylindrical vestibule forming member pivotally mounted in the end of each vehicle element for pivotal movement relative to the vehicle element about a vertical axis passing through the center of said spherical joint, said semi-cylindrical members having passageway openings in the sides thereof to afford communication with the vehicle elements, and extensible surfacing material joining adjacent semi-cylindrical members to provide surface continuity between the same while permitting said semi-cylindrical members to move relatively to each other in a vertical plane about the spherical joint.
  • An articulation device for connecting the adjacent ends of adjacent vehicle elements comprising a supporting frame member, a spherical joint forming surface on said frame member, an arm extending from the end of one vehicle element and having a spherical joint forming surface provided thereon, an arm extending from the end of the adjacent vehicle element, and having a portion extending between and having surfaces cooperating with the spherical joint forming surfaces of the frame member and first recited arm to form a spherical joint interconnecting the vehicle elements and frame, a semicylindrical vestibule forming member pivotally mounted in the end of each vehicle element for pivotal movement relative to the vehicle element about a vertical axis passing through the center of said spherical joint, said semi-cylindrical members having passageway openings in the sides thereof to afford communication with the vehicle elements, extensible surfacing material joining adjacent semi-cylindrical members to provide surface continuity between the same while permitting said semi-cylindrical members to move relatively to each other in a vertical
