Definitions

  • the present invention relates to railway vehicles in general comprising two carriages the bodies of which communicate with each other through an intercommunication passage, in which each of the carriages has a respective bogie close to the zone of intercommunication connected to the body by means of a centre plate.
  • the invention relates to an intercommunication passage of the type comprising a rigid tubular element beneath which is fixed a connecting bar carrying attachment parts at its ends which are fixed to the bogies through the said centre plates, the tubular element having a base wall with substantially semicircular guide ends which bear slidably on complementary parts of the floors of the two bodies, two side walls and an upper wall.
  • the object of the present invention is to provide an intercommunication passage of the type mentioned above having a shape such as to allow better use to be made of the space available for passengers in the passageway between the bodies of the two carriages so as considerably to increase the passenger-carrying capacity of the vehicle, while at the same time ensuring convenient and easy movement of passengers between the two bodies.
  • the present invention provides an intercommunication passage for a tramway railway vehicle of the type defined above, characterised in that a rocker support arm is articulated to the centre of the upper wall, the ends of which are connected by respective connecting rods to the roofs of the two bodies.
  • each side wall of the tubular element there is interposed an intermediate cover carried by the projecting floor and by the roof of the respective body and pivotally connected at its upper end to the upper wall of the tubular element.
  • the said guide ends of the floor of the tubular element are defined by sector plates articulated to the remaining part of the floor of the tubular element.
  • the shape of the intercommunication passage according to the invention by virtue of a rigid connection beween the two bodies, forms a wide and spacious passage for pssengers without any discontinuity in the level of the floor, while at the same time allowing the necessary relative movements between the two bodies, that is, rotation relative to the vertical axis of each bogie (movement of the vehicle around bends), rotation about a transverse horizontal axis (movement of the vehicle through vertical curves) and rotation about a longitudinal axis (passage of the vehicle over rails which are askew), by virtue of the fact that the rolling movements of the two bodies are independent of each other.
  • reference V generally indicates a tramway vehicle formed by a pair of carriages C 1 , C 2 articulated together through a central intercommunication passage 10 between the bodies B i , B 2 of the carriages.
  • the vehicle V has a pair of conventional drive bogies M i , M 2 with wheels of conventional diameter close to the front end of the body B 1 and close to the rear end of the body B 2 respectively.
  • the adjoining ends of the two bodies B i , B 2 have respective support bogies P 1 , P 2 with smaller diameter wheels.
  • the support bogies P i , P 2 are preferably of the type forming the subject of Italian Patent Application No. 68510-A/82 in the name of the same Applicants and will thus not be described below for brevity.
  • the wheels of the two support bogies P i , P 2 have a diameter equal to about half (35 cm) that of the wheels of the drive bogies M i , M 2 allowing the vehicle V to be provided with a floor, generally indicated F in Figure 1, which is completely lowered along its whole length between the two drive bogies M i , M 2 at a height normally of the order of 45 cm from the plane of the track, consequently ensuring easier and more convenient access for passengers through the doors D or the vehicle.
  • each of the bodies 8 1 , B 2 includes a roof 12, side walls 14 and a base wall or floor 16 having a part 18 projecting beyond the end of the roof 12 towards the intercommunication passage 10.
  • the free end of each projecting part 18 has a semicircular shape with a radius of curvature directed towards the interior of the respective body B i , B 2 and defining a bearing and sliding guide 20 the function of which will be clarified below.
  • each of the bogies P 1 , P 2 is connected to the projecting base part 18 of the respective body B 1 , B 2 through a respective centre plate generally indicated 22 the outer ring of which, indicated 24, is fixed to the bogie.
  • the intercommunication passage 10 comprises a rigid tubular element 25 comprising an upper wall 26 surmounted by a roof 28, a base wall 30 and two side walls 32.
  • the base wall 30 has semicircular guide parts 34 at its two ends which are defined, except in their zones adjacent the side walls 32, by sector plates 36 articulated to the remaining part of the base wall 30 about respective hinge pins 38.
  • the semicircular guide parts 34 slidably bear on the semicircular parts 20 of the projections 18 of the floors 16 of the two bodies B 1 , B 2 with the interposition of sliding blocks 40.
  • a reinforcing cross member 42 Beneath the base wall 30 is fixed a reinforcing cross member 42 to which is rigidly connected a longitudinal connecting bar 44 connected to two attachment parts 48 at its ends through articulated couplings 46, the parts 48 being rigidly connected to the rings 24 of the two centre plates 22.
  • Reference 50 indicates a rocker support arm articulated at its centre to the roof 28 about a vertical pivot pin 52.
  • the ends of the rocker arm 50 are in their turn articulated by respective vertical pins 54 to two connecting rods 56 pivotally connected by pins 58 parallel to the pins 54 to two attachment structures 60 fixed to the ends of the roofs 12 of the two bodies B 1 , B 2 .
  • Each cover 62 is connected to the projecting part 18 of the floor 16 and to the roof 12 of the respective body B 1 , B 2 by means of respective hinges 66, 68 and its upper part is connected to the upper wall 26 of the tubular element 25 so as to be rotatable about a respective vertical pin 70.
  • the bases of the curved walls 63 of the covers 62 are in sliding contact, by means of brushes or flexible seals, not shown, with the guide parts 20 and 34 while the sides of the covers 62 facing inwardly of the bodies B 1 , B 2 are connected to the corresponding side walls 14 thereof by means of flexible closure elements 72 normally of elastomeric material.
  • the shape of the intercommunication passage 10 described above clearly allows the necessary relative movements between the carriages C 1 , C 2 and the rigid tubular element 25 during movement of the vehicle V, that is:
  • the intercommunication passage 10 allows the maximum use to be made of the space between the two bodies (B,, 8 2 ) which is all to the advantage of the carrying capacity of the vehicle, at the same time ensuring convenient and safe movement of passengers between the bodies themselves.
