Definitions

  • the present invention relates to a railway bogie supporting a car body plumb with the side members, using fluid suspension elements, the longitudinal, lateral and rotational forces being transmitted and absorbed by means of connecting rods and links which are supported in whole or in part by said fluid suspension elements. More particularly, the invention relates to a bogie without a load cross member or dancer for the regional high-speed metro, having fluid springs, in particular pneumatic, mounted on each spar and elastically supporting the car body.
  • the state of the art includes a large number of bogies and suspension systems for supporting bodies of railway vehicles.
  • the support systems that use a cross member carried by the springs and articulated to the car chassis around a vertical axis in the center of the bogie or near it and the support systems mounted in direct alignment with the side members in which case the vehicle body is generally slidably mounted directly on springs or on support surfaces on the springs without a cross member being interposed between the springs and the body.
  • the load on the body or the vertical forces exerted by the body are indirectly supported or are offset by a position directly above the side frames of the bogie.
  • US Patent 3,646,893 describes a bogie having a suspension frame intended to rigidly interconnect four tubular bellows which receive the air pressure from a pressure tank housed in the body.
  • the arrangement adopted causes wear in the sliding joints located between the tubular bellows and the suspension frame. This state of the art is not particularly suitable for joints in the regional high-speed metro service or in cases where there are many curves.
  • US Patent 3,774,549 illustrates an articulated bogie in which the body is carried vertically above the side members by supports supported by springs, without the interposition of a crosspiece between said springs and the body.
  • the air intended for the springs is supplied by tanks forming part of the bogie so as to eliminate the problem which consists in keeping a constant coincidence between the orifices of the support plates of the body and an orifice in the suspended load-bearing element.
  • the central pivot of the body is connected to a transverse connection system which is not intended to transmit and absorb the lateral, longitudinal and rotational forces between the body and the side members and which constitutes a relatively rigid connection in the vertical plane.
  • the object of the present invention is to remedy the drawbacks of known bogies.
  • the invention as characterized by the claims aims to provide a hinged interconnection assembly between the central pivot and longitudinal pendulums which are resiliently mounted on pneumatic or hydraulic springs disposed on the longitudinal members and provided with surfaces of support and support to support the body.
  • the invention provides direct suspension of the total weight of the body directly above the side members by one or more fluid springs arranged on the side members and provided with support and support surfaces for the body frame.
  • the longitudinal pendulums are provided to interconnect the springs on the same spar and to provide a support and support surface to support the total weight of the body directly above the spars.
  • the pair of longitudinal balances has seals disposed between the sliding bearing surface of the body frame and holes in the longitudinal balances which provide fluid pressure to the springs.
  • Longitudinal pendulums are interconnected elastically to a central coupling part by means of connecting rods which are articulated to each longitudinal balance and to the central coupling part to transmit and absorb the longitudinal and lateral forces of the body to the longitudinal balance.
  • the longitudinal pendulums provide the sliding support of the body plumb with the side members and provide the support for part of the weight of the central coupling body and connecting rods.
  • the articulated interconnection between the central coupling piece, the connecting rods and the longitudinal beams in combination with the elastic interconnection between the connecting rods and the bogie chassis allows the transmission and absorption of lateral, longitudinal and rotational forces between the body and chassis.
  • the new articulated interconnection is particularly advantageous in the uses of regional express and high-speed metro or on curved tracks and if the fluid reservoir for actuating the fluid springs is placed in the car body or at a location remote from the bogie. In these applications the rotational forces exerted between the body and the bogie have a detrimental effect on the conservation of the joints arranged between the bogie and the body, particularly in the case of insufficient air pressure at the air springs.
  • the use of longitudinal pendulums to support the weight of the car body above the lateral chassis provides a better distribution of loads and surface contact between the chassis of the chassis and the longitudinal balancers.
  • the outer sides of the side members are free to allow the installation of current connectors and the vertical damper can be placed in the center of the bogie.
  • the bogie according to the invention serves to reduce the effect of the longitudinal, lateral and rotational forces of the body on the seals which increases the ease of maintenance and the service life and provides advantages as regards the operation.
  • the invention reduces maintenance and allows a more efficient arrangement of parts and organs than in the prior art.
  • the invention makes it easier to maintain the parts and organs of the bogie because that it allows the body and the bogies to be lifted without requiring special equipment.
  • the lifting of the body and the bogie can be carried out easily without special tools by lifting the bogie by the pivot points in order to allow and facilitate the inspection and maintenance of the sealing device.
  • the articulated interconnection of the longitudinal beams with the connecting rods and the central coupling piece facilitates the maintenance and replacement of the individual components.
  • the bogie provides greater elasticity and absorption of forces to facilitate maintenance and the operating life of the bogie.
  • the invention is particularly suitable for articulated chassis to contribute to overall resilience and is advantageously used in regional high-speed metro networks and for infrastructures comprising sections of curved and irregular track.
  • the bogie has longitudinal members on which are mounted fluid springs supporting the body and it is characterized in that it comprises a pair of longitudinal pendulums mounted on said springs and intended to support the weight of the body and a pair of connecting rods each articulated with a balance and a central coupling piece provided with means for the relative pivoting of the body and the bogie.
  • each connecting rod is connected to the side members by an attachment rod.
  • the bogie comprises a transverse damper mounted between said central coupling piece and said longitudinal members.
  • the bogie 20 comprises a bogie frame 22 placing two longitudinal beams 24 and 26 on which four wheels are rotatably mounted via axles 30 and 32. Each axle box is trapped at the end of a beam with the interposition of an elastic sleeve allowing a slight deformation.
  • the bogie 20 in its preferred embodiment is a motor bogie such as those used in the regional high-speed express metro networks and it includes drive motors 34 and 36.
  • the longitudinal members 24 and 26 preferably comprise cross-members 38 and 40 respectively which are coupled by bearing assemblies 42 and 44 which preferably allow relative pivoting between the side members 24 and 26 and allow the wheels to remain in contact with irregular track sections.
  • the principle of the articulated bogie is known per se and will not be described more fully. The organs of the articulated bogie cooperate with the elements of this bogie to impart greater elasticity to the overall combination.
  • the bogies 20 support the total weight of the car body 46 plumb with the side members 24 and 26.
  • the vertical force total or the load exerted by the body 46 is resiliently supported plumb with the side members 24 and 26 by pneumatic or hydraulic springs 48 of the cushion type.
  • two pneumatic springs 48 are arranged on each beam 24 or 26.
  • a pair of longitudinal beams 50 and 52 longitudinally couple the pneumatic springs 48 on each of the beams 24 and 26.
  • Longitudinal beams 50 and 52 are designed to occupy and close the tops 54 (FIG. 3) of the air springs 48 and they are provided with orifices 56 for supplying air or fluid pressure to the air springs 48.
  • each pneumatic springs is closed by a plate 58 disposed on a beam.
  • the upper ends of the air springs are tightly joined to the longitudinal pendulums in order to maintain the air pressure supplied to the orifices 56 of the longitudinal balancers 50 and 52.
  • the longitudinal pendulums 50 and 52 in combination with the pneumatic springs 48 support the weight of the body, bearing on the chassis 60 and 62 of the body 46, plumb with the side members 24 and 26.
  • the air pressure is supplied from two tanks 64 and 66 arranged on the car body 46 and connected by conduits 68 and 70 to the orifices 56 in the longitudinal beams so as to provide an elastic support for the weight of the body applied to each of the longitudinal beams 50 and 52 .
  • the bogie supports the load or the vertical force exerted by the car body 46 plumb with the side members.
  • the load on the longitudinal members 24 and 26 constitutes the total vertical load or force exerted by the body on each of the longitudinal pendulums 50 and 52 in association with the pneumatic springs 48.
  • the weight of the body is partially supported by the longitudinal pendulums 50 and 52 and is denoted F2 in FIG. 10 and the remaining part of the weight of the body 46 is directly supported by the air pressure supplied to the pneumatic spring 48 and is denoted F1 in FIG. 10.
  • the vertical forces on the joints 72 in conjunction with the rotational forces acting on the joints 72 during the rotation of the car when it travels the curved sections of track is directly attributable to the sliding forces exerted on the joint and to the longitudinal and lateral forces between the bogie and the body. These efforts are reduced if an articulated connection exists between the central pivot and the air suspension system disposed on the side frames 24 and 26 of the bogie.
  • the known joint 72 (FIG. 10) supports a heavy load and in the case of insufficiency the air pressure carries the total load of the box. The lack of protection of the seals subjects them to wear and fatigue, particularly in the event of insufficient air pressure.
  • FIGS. 3 and 8 The articulated and elastic interconnection between the body 46 and the bogie 20 is better illustrated by FIGS. 3 and 8 in which a central pivot 76 is disposed approximately at the center of the transverse spacer 77 of the body 46.

  • the central coupling piece 78 preferably comprises a bearing mount 84 (FIG. 1) to couple a transverse damper 86 which is linked to a console 87 mounted on the cross-member 38 (FIG. 3).
  • the function of the bearing assembly and the shock absorber 86 is to facilitate the damping of the lateral forces between the central pivot 76 of the body and the bogie 20.
  • the action of the rotational forces on the seals is illustrated diagrammatically in the figure 11.
  • the amplitudes of the forces are significantly reduced due to the numerous pivoting and elastic joints between the central coupling part and the longitudinal pendulums as will be described in detail below.
  • the central coupling piece 78 does not support the weight of the body but on the contrary is mainly used for the interconnection of the central pivot 76 of the body with the bogie 20 to participate in the transmission of the longitudinal and lateral forces which result from the operation of the bogie 20 during the movement of the body 46.
  • the central coupling piece 78 comprises bearing assemblies 88 and 90 having axes 92 and 94 respectively for the articulated and pivoting coupling with connecting rods 96 and 98.

  • the connecting rod 116 could be articulated to the side members 26 of the bogie.
  • the connecting rod 118 is articulated similarly to the cross member 38 of the bogie 20 or can be articulated directly to the side members 24 in the same manner as the connecting rod 116.
  • the mounting brackets 122 can be used on the cross members 38 and 40- for the articulated mounting of the connecting rods 118 and 116 respectively.
  • stops 124 can be provided on the connecting rods 116 and 118 to limit the rotational movement of said connecting rods and to lift the load of the bogie linked to the body 46.
  • a corresponding stop 126 can be used to form the second part of the stop element and can be placed on the crosspieces to facilitate the lifting of the bogie 20.
