Definitions

  • the present invention relates to a rocking bed base and a secondary suspension having it.
  • Bed springs are already known which are used in secondary suspensions of railway vehicles such as wagons, railcars or locomotives to ensure the suspension of the vehicle body with respect to a chassis on which axle-wheel assemblies are mounted by the vehicle. intermediate of a primary suspension.
  • a bogie comprising for example two axles and four wheels (or with three axles for example)
  • two or four subsets of secondary suspension each of which has a single bed base or a pair of bed bases to obtain a horizontal softening, and one or more metal springs arranged (s) in series with the bed frame or between the bed bases and whose function is to obtain the desired vertical flexibility for the secondary suspension.
  • the patent application EP 155 209 relates to an elastic bearing device which consists of a laminated elastomeric ring connected in series with a helical spring to form a secondary suspension of railway bogie.
  • an elastic bearing device which consists of a laminated elastomeric ring connected in series with a helical spring to form a secondary suspension of railway bogie.
  • This device has only poor tilting properties and therefore poor decoupling of the horizontal stiffness as a function of the direction of horizontal stress.
  • the patent FR 1 540 148 describes a subassembly comprising two helical springs whose upper end is connected to the body of the vehicle and whose lower end is connected to a support pivoting freely around a hinge (or a knife assembly), lateral buffers being provided to serve as an elastic stop for tilting the pivoting support.
  • this device has integration and maintenance issues.
  • the patent BE 700027 describes a vehicle body support member associating a spring with a single hemispherical ball.
  • the implementation of a ball joint does not make it possible to differentiate the characteristics according to the directions in the horizontal plane.
  • the patent application FR 2 801 268 combines in series a helical spring and two ball joints laminated elastomer or not, mounted head to tail. Such a device imposes in practice a large footprint in the direction of the height to ensure the required performance. In addition, the use of ball joints does not make it possible to differentiate the characteristics according to the horizontal directions.
  • the patent application FR 2 354 229 proposes to overcome the metal spring or springs by associating in series a frustoconical spring having a high axial flexibility to ensure vertical deflections of the suspension, and a low horizontal flexibility to provide a vertical guide function, and a cylindrical spring having a high vertical stiffness to support the weight of the body and high horizontal flexibility to accommodate the relative horizontal movements of the body and the bogie.
  • This device also does not differentiate the features in the horizontal directions.
  • the laminated frustoconical spring can be problematic to ensure high vertical deflections and to ensure a vertical stiffness independent of the load level (the characteristic axial force / axial displacement tends to be nonlinear for this kind of part), this to what is added the problem of creep and thus of rigging to ensure the height of the floor relative to the platform over time.
  • the inventors of the present Application consider that it would be desirable to make it possible to differentiate the lateral decoupling performance while limiting the vertical space requirement.
  • the present invention proposes a tilting bed base that can be integrated with a suspension subassembly, in particular a secondary vehicle suspension, which has a parallel-type architecture in which the functions are distributed between a central pivot and at least a pair of elastic studs mounted on either side of the central pivot.
  • the first horizontal axis is a preferred tilting axis of the bed, for which the pivot and the resilient pads are biased mainly angularly.
  • This parallel architecture has the significant advantage of limiting the vertical space, and thus avoid a major drawback of known devices which is to limit the performance of the device due to the constraints of vertical space. Indeed, the constraints of vertical space often require undersizing parts that can not therefore fully meet the specifications, which affects among other things the comfort of passengers.
  • the geometry of the central pivot is preferably frustoconical in order to reduce its conical stiffness, and thus reduce its stiffness in tilting (which is not differentiated by the central pivot.
  • Said cylindrical or frustoconical elastic element may be at least partly made of elastomer, in particular of laminated elastomer.
  • Said elastic pads may be metal cushions, or be at least partly elastomeric, especially laminated elastomer.
  • the ratio between the horizontal stiffnesses of the central pivot and of all the blocks may be greater than or equal to 1 and may be for example between 5 and 50, and preferably at least 10.
  • the ratio between the vertical stiffness K ' AP of all the pads and the central pivot K AP may be greater than or equal to 1 and may be for example between 5 and 50, and preferably at least 10.
  • the ratio between the horizontal stiffness and the vertical stiffness of the central pivot may be in particular between 1 and 5 and for example between 2 and 5, and / or the ratio between the vertical stiffness and the horizontal stiffness of a stud may be greater or equal to 10 and can be for example between 50 and 500.
  • the bed base can be characterized in that the elastic or frustoconical element of the central pivot has at least one pair of cells disposed symmetrically on either side of the central pivot and whose median planes are aligned on a second horizontal axis perpendicular to said first axis.
  • the bed base can be characterized in that at least one central pivot has an abutment integral with its inner part and in that this abutment has a flange spaced apart by a functional clearance j of the outer part of said central pivot to limit the displacement in tension of the elastic element of said central pivot.

  • the subassembly may be characterized in that it comprises two so-called rocking bases mounted head to tail, or suspension springs being arranged between the second supports of the two bed bases.

  • H susp designates the height of the secondary suspension incorporating the bulk of the bed frames 32 and 33.
  • the x direction is the longitudinal direction of the vehicle, which is that of its movement in a straight line.
  • the direction is the transverse direction of the vehicle, and the direction z, orthogonal to the two previous ones, is the vertical direction.
  • the direction u (see also figure 2b ) designates the preferred tilting axis of the rocking bases 32 and 33, and the direction v, the horizontal direction perpendicular to the directions u and z.
  • u is the longitudinal direction of the bedsteads, and v is the transverse direction.
  • the rocking bed bases have the function of providing a differentiated decoupling, with in particular a privileged tilting around the u-axis and a limited tilting around the v-axis of the mattresses, whereas the metal springs typically provide the obtaining the desired vertical stiffness for the secondary suspension.
  • the differentiated decoupling is thus obtained thanks to tilting bed bases that have different stiffness characteristics according to the horizontal directions.
  • O1 and O2 are the geometric centers of all upper bed bases 32 and 33, each bed frame 32 having a center A1, B1, C1, D1, and each bed base 33, a center A2, B2, C2, D2.

  • the radial stiffness K RP of the pivot 50 is much greater than the K CP shear stiffness of the set of pads 60, it is the pivot 50 which takes up most of the horizontal force.
  • the stiffnesses are also added, and the stiffness in this direction is the sum of the axial stiffness K AP of the pivot 50 and the axial stiffness K ' AP of the pads 60 taken as a whole (namely the sum the stiffness of the pads), and since the axial stiffness K AP of the pivot 50 is much smaller than the Axial stiffness K ' AP of the pads 60, it is the pads 60 which take up most of the vertical force.
