Definitions

  • ABSTRACT La Point Assistant Examiner-Howard Beltran Attorney-Sommers & Young
  • This invention relates to a railway vehicle suspension in which the vehicle is supported on wheelsets or double axle bogies by way of a yaw suspension which allows relative yawing movements between the vehicle and the wheelsets or bogies.
  • This yaw suspension in cludes a resilient arrangement, such as a series-connected damper and spring, whose dynamic stiffness increases with increase in the yaw velocity. In this way any high frequency yawing movements, such as are caused by track irregularities, are quickly damped out.
  • Yaw suspensions are provided in railway vehicles to permit yawing, that is relative rotation of the vehicle body and the wheelset about a vertical axis, against a resilient restraint.
  • This invention is applicable 'to yaw suspensions which are directly between the wheelset and the vehicle body or between a bogie frame and the vehicle body or between the wheelsets and a bogie frame. Hence it is applicable to freight and passenger vehicles whether of two axle, bogie or other. configuration.
  • the yaw suspension includes a resilient arrangement whose dynamic stiffness increases with increase in yaw velocity.
  • the yaw suspension can be arranged, on the one hand, to permit substantially unrestrained yawing at low yawing velocities such as are encountered when 3 the vehicle negotiates a curve'in the track so that the wheelsets remain radially aligned tothe track curvature, and, on
  • the resilient arrangement of the yaw suspension may comprise a hydraulic damper and spring in series and, optionally, a further spring can be provided in parallel with the series-connected damper and spring.
  • FIG. 1 is a plan view of a yaw suspension connected between a single axle wheelset and the vehicle body.
  • F lG.y2 is a plan view of a second arrangement where a yaw suspension is connected between a two axle bogie and the vehicle body.
  • FIG. 3 is a side view of a third arrangement where a yaw suspension is connected. between a pair of single axle wheelsets and a geometrically steered member secured at its outer ends to adjacent coaches. of the vehicle.
  • FIG. 4 is a partial plan view of the arrangement shown in FIG. 3.
  • FIG. 1 a single axle wheelset is rotatably mounted at its outer ends in axle boxes 11.
  • the axle boxes 11 support a vehicle body by a suitable suspen sion (not shown) which allows vertical, lateral and yawing movements between the wheelset and the body.
  • a hydraulic damper 12 connected in series with a spring 13 is connectedbetween each of the axle boxes 11 and the vehicle bodywork 14.
  • the longitudinal axes of each of the dampers l2 and springs 13 are arranged to be as near horizontal as possible.
  • the characteristics of the dampers 12 are arranged such that substantially no restraint is offered to low frequency yawing movements of the wheelset relative to the body, such as occur when the railway vehicle is negotiating a curve in the track. In this situation, the wheelset is permitted to yaw so as to take up a position in which the axle axis lies substantially radially to the curve.
  • any high-frequency yawing movements caused for example by track irregularities, are quickly damped out by the high resistance offered by the dampers 12 to any such high-frequency movements.
  • the springs 13 can be of any convenient type, and their stiffness is chosen in accordancewith the mass of the wheelset to be controlled.
  • a second auxiliary spring 15 may be connected in parallel with the damper l2 and spring 13. This spring 15 will normally be of lesser stiffness than The spring 13 and is included for stability purposes.
  • FIG. 2 illustrates a corresponding arrangement in which a pair of wheelsets 10 are mounted in a bogie frame consisting of a pair of longitudinal members 16, interconnecting the axle boxes 11 of the two wheelsets, and a central transverse member 17.
  • the member 17 is rigidly connected to the longitudinal member 16.
  • the vehicle body is supported on the bogie frame by a vertical and lateral suspension (not shown) which allows the bogie to yaw relative to the body about the center point of the transverse member 17.
  • the series-connected dampers l2 and springs 13 are in'this embodiment connected between the outer ends of the transverse member 17 and the vehicle body 14.
  • dampers 12 The operation of the dampers 12 is exactly as described with reference to FIG. 1 in that no resistance is offered to any low frequency yawing movement of the bogie relative to the body, whilst high frequency yawing movements are quicklydamped out.
  • FIG. 3 an arrangement is shown in which adjacent coaches 18 and 19 of the train are joined by a central pivotal joint 20.
  • a steering beam 21 extends across this joint 20 between the two coaches 18 and Y19 and is connected at its ends to the coach bodies by pin joints or other suitable joints 22.
  • This type of connection between vehicle bodies is fully described in co-pending application Ser. No. 849,322, filed Aug. 12, I969, and now abandoned and superseded by continuation-inpart application ser. No. 129,899, filed Mar. 31, I971.
  • Traction rods 23 are connected between the axle boxes 24 at each end of a pair of wheelsets 25 and 26, and one end of a pair of pivoted beams 27. These beams 27 are pivotally mounted on the steering beam 21 by joints 28 so as to allow the beam 27 and hence the wheelsets 25 and 26 to yaw relative to the steering beam.
  • This yawing movement is controlled by means of a pair of hydraulic dampers 29 and springs 30 connected in series between the ends of the beam 27 and arms 31 extending laterally from the steering beam 21.
  • the operation of the combined dampers 29 and springs 30 is to damp out any high frequency yawing movements of the wheelsets 25 and 26 relative to the steering beam 21. As with the embodiments shown in FIGS.
  • a second spring may be connected in parallel to each series-connected damper 29 and spring 30.
  • a vertical suspension is shown diagrammatically by the elements 33, 34, 35 and 36, although it will be understood that any conventional type of vertical suspension means may be employed instead of that shown.
  • FIGS. 3 and 4 in which a pair of wheelsets are independently mounted from the steering beam 21, is equally applicable to an arrangement in which a double axle bogie is mounted on the beam 21.
  • This arrangement is similar to that described with reference to FIG. 2 except that the bogie frame is mounted on the-steering beam andthe series connected dampers and springs are connected between the frame and the steering beam.
  • a railway vehicle including a supporting member, a wheelset, yaw suspension means operatively connecting said wheelset to said supporting member so as to permit yawing movements relative thereto, said yaw suspension means including resilient means which resists motion about a yaw axis between said wheelset and said supporting member and having a dynamic stiffness which increases with increase in the yaw velocity, whereby high frequency yawing oscillations of the wheelset relative to the supporting member are quickly damped without imparing the low frequency yawing movements of the wheelset.
  • a railway vehicle as claimed in claim 1 wherein said resilient means comprises a damper and a spring connected in series.
  • a railway vehicle as claimed in claim 1 which further includes a vehicle body and wherein two said wheelsets are arranged as a double axle bogie which includes a bogie frame, said yaw suspension means being connected between said bogie frame and the vehicle body.
  • a railway vehicle as claimed in claim 1 which further includes a vehicle body and wherein two said wheelsets are arranged as a double axle bogie which includes a bogie frame, said yaw suspension means being connected between said bogie frame and the vehicle body.
  • said supporting member is a rigid beam extending across the interconnection between two adjacent vehicle bodies and which is connected at its ends to the two vehicle bodies at a distance longitudinally of the vehicle bodies from their interconnection with each other, said yaw suspension being connected between said rigidbeam and at least one wheelset mounted on said beam.
  • a railway vehicle as claimed in claim 5 wherein a second beam is provided, extending transversely of the rigid beam and pivotally mounted thereon so as to be able to yaw relative thereto, the wheelset being connected to said second beam such that the second beam follows all yawing movements of the wheelset relative to the rigid beam and wherein the yaw suspension is connected between the second beam and said rigid beam.
