Definitions

  • the present invention relates to installations of the type of suspended railways, that is to say in which the vehicles are designed to roll on a girder which carries them, through the intermediary of articulated systems, the said girder being for example hollow and comprising at its base a slot through which pass certain elements of the said systems, as has already been described in particular in French Patents Nos. 1,072,538 and 1,068,532, filed respectively on December 18 and 28, 1952, by the Socit Anonyme iFrangaise dEtudes, de Gestion et dEntreprises, and in the patent application filed by the same company on March 10, 1958, for Suspended Railway.
  • the invention has especially for its object to improve the conditions of horizontal suspension and of comfort of the above-mentioned vehicles, at the same time simplitying the erection, and to reduce the torsion stresses on the girder due to the effect of the transverse forces (eccentricity of the load, action of the wind, etc.).
  • the invention mainly consists in arranging the articulated systems intended to suspend the vehicles from the bogies or other devices providing the rolling action on the carrying girder, in such manner that these systems are similar, in a mean transverse plane in which the coupling is effected, to an articulated quadrilateral or trapezium, the lateral sides of which (embodied by connecting rods or other elements) tend to converge towards a point lo cated above the girder in the vicinity of the centre of torsion of this latter in the said plane.
  • the invention comprises certain other arrangements which will preferably be employed at the same, and which will be more explicitly dealt with later, in particular:
  • a second arrangement relating to installations of the kind in question employing suspension by articulated systems consists in so arranging matters that the upper axes of articulation of the said systems are located above the plane of the rolling tracks on the girder, the connecting rods which are comprised in the said systems being to this end suitably incurved so as to be able to pass through the slot in the girder;
  • a third arrangement relative to installations of the kind in question for which the vehicle comprises two articulated suspension systems distributed over the length consists in providing respectively in these two systems, two damping devices or the like, conjugated with each other in such manner that their reactions tend to act in opposition to any de-phasing of the respective oscillations of the said systems (so as to prevent a pendular oscillation), the conjugation being hydraulic in particular, in the case of hydraulic damping devices.
  • the invention is more particularly directed to certain forms of application and also to certain forms of embodiment of the said arrangements; and it is still more particularly directed, by way of new industrial products, to installations of the kind in question comprising the application of these same arrangements, together with the special elements proper to their construction.
  • FIG. 1 of these drawings illustrates diagrammatically aninstallation of a suspended railway with an articulated suspension constructed in accordance with the invention.
  • IFIGS. 2 and 3 show respectively and partially, with parts broken away, a transverse section in side view of an installation constructed according to the principle of FIG. 1.
  • FIG. 4 shows in diagrammatic perspective a further arrangement of the invention, relative to the suspension of a suspended vehicle.
  • the vehicle may be subjected to lateral stresses, such as those due to the wind or to an unequal distribution of the load.
  • each of these systems is substantially similar to'an articulated trapezium, the lateral sides of which converge towards a point 0 which is located above the girder and is maintained in the proximity of the centre T.
  • the points A, B, C, and D form a trapezium, the sides CA and DB converge towards a point 0 which is located in the normal vertical position in the immediate proximity of the centre of torsion T.
  • the centre of torsion T is located at a height of the order of 2.0 to 2.50 metres above the rolling plane.
  • the triangle of suspension CDO arranged following the trapezium having for example a base CD of the order of 0.5 to 0.6 metre (or more), it is found that for the maximum excursions of the vehicle on each side of the vertical (the points C and D moving to C and D and the point for example to 0 the incursions e of the said point 0 on each side of the centre T cannot appreciably exceed one metre, or even in general remain less than one metre.
  • the part 8 on which the above-mentioned rods are articulated along the axes A and B is arranged (in a pivotal manner about a horizontal shaft 15) at the lower portion of a central suspension which forms a vertical pivot 7, this suspension being guided by any appropriate means at 6a and 6b in the chassis 6 of the bogie, to which it is coupled by a suitable elastic suspension.
  • This suspension comprises for example:
  • springs 9 mechanical, pneumatic, hydropneumatic springs, etc. interposed between the said chassis and an upper plate or cross-member it ⁇ ;
  • the guiding action at 6a and 6b can be obtained, as shown in fulll ines, by guiding sheaths. It is however also pgssible, as shown in broken lines at 19, to employ connecting rod systems with elastic articulations arranged longitudinally and/or transversely.
  • Damping means of any appropriate type are combined with the unit. Such damping devices can be seen at 17 and 18 in FIGS. 2 and 3, interposed between the crossmembers 14 and the body on the pivotal shafts 20 and 21.
  • this arrangement being applicable in a general manher to all suspended vehicles comprising two articulated suspension systems, whatever the nature of these systems may be, conjugation means are provided between the damping devices or the like with which these systems are provided, said means being intended to act in opposition to an oscillating movement.
  • each articulated system comprises, as shown in FIGS. 2 and 3, two damping devices, for example hydraulic, especially of the cylinder type 17 and piston 18, matters are so arranged that (FIG. 4):
  • one of these two damping devices carries out normally and independently its function of damper or limiter in order to control the amplitude of the actual movements of the said system
  • the two other damping devices belonging respectively to the two articulated systems are coupled to each other in such manner as to act in opposition to a possible de-phasing between the respective oscillations of the said systems, and therefore in such manner as to prevent longitudinal oscillation.
  • conduits which are at least partially flexible such as shown at 22 and 23, these conduits being crossed so as to mutually assist in achieving the desired result.
  • the two corresponding damping devices will in turn be arranged in a crossed manner between their respective pivotal shafts 20 and 21 (it will be seen from FIG. 4 that for one of them, it is the rod 24 which is coupled to the shaft :29, while for the other, it is the cylinder 17).
  • a system of the kind described which comprises, in combination, a girder having two rolling tracks located side by side and extending in the longitudinal direction of said girder, said girder having, in every plane transverse to said direction, a center of torsion located above said rolling tracks, at least one bogie having a longitudinal vertical plane of symmetry and comprising wheels resting on said rolling tracks and a chassis supported by said wheels, a vehicle located under said girder having a longitudinal vertical plane of symmetry and suspension means interposed between said bogie and said vehicle, said suspension means comprising at least one pair of links each pivoted to said chassis and to said vehicle about axes parallel to said longitudinal direction, the two pivot axes on said chassis being symmetrical with respect to said first mentioned plane of symmetry and the two pivot axes on said vehicle being symmetrical with respect to said second mentioned plane of symmetry, so that the plane transverse to the longitudinal direction passing through said links intersects said pivot axes at the apexes of a trapezium, said pivots being so located that the lateral
  • a system of the kind described which comprises, in combination, a hollow girder having a lower web provided with a continuous longitudinal middle slot, the portions of the upper face of said lower web located on either side of said slot forming two rolling tracks, said girder having, in every plane transverse to said direction, a center of torsion located above said rolling tracks, at least one bogie having a longitudinal vertical plane of symmetry and comprising two pairs of wheels resting on said rolling tracks and a chassis supported by said wheels, a vehicle located under said girder having a longitudinal vertical plane of symmetry and at least two articulated suspension means interposed between said bogie and said vehicle, each of said suspension means comprising at least one pair of links extending through said slot and each pivoted to said chassis and to said vehicle about axes parallel to said longitudinal direction, the two pivot axes on said chassis being symmetrical with respect to said first mentioned plane of symmetry and the two pivot axes on said vehicle being symmetrical with respect to said second mentioned plane of symmetry, so that the plane transverse to the longitudinal direction passing through
  • a system of the kind described which comprises, in combination, a hollow girder having a lower web provided with a continuous longitudinal middle slot, the portions of the upper face of said lower web located on either side of said slot forming two rolling tracks, said girder having, in every plane transverse to said direction, a center of torsion located above said rolling tracks, at least one bogie having a longitudinal vertical plane of symmetry and comprising two pairs of wheels resting on said rolling tracks and a chassis supported by said wheels, a vehicle located under said girder having a longitudinal vertical plane of symmetry, at least two aritculated suspension means interposed between said bogie and said vehicle, each of said suspension means comprising at least one pair of links extending through said slot and each pivoted to said chassis and to said vehicle about axes parallel to said longitudinal direction, the two pivot axes on said chassis being symmetrical with respect to said first mentioned plane of symmetry and the two pivot axes on said vehicle being symmetrical with respect to said second mentioned plane of symmetry, so that the plane transverse to the longitudinal
