Definitions

  • the invention relates to a support Rail vehicle on a bogie according to the Preamble of claim 1.
  • Such a box support is from the EP-A-0 271 690 known.
  • the through the vertical Prestressing forces of the loaded spring elements rail-like support pieces allow relatively strong Inclinations of the spring plate in relation to the neighboring one Vehicle part - body or bogie - in the vehicle's longitudinal direction, and correspondingly lower inclinations of the Spring plates in the transverse direction of the vehicle.
  • the Turning movements of the bogie relative to the box the support devices both in the longitudinal direction and deflected in the transverse direction.
  • the relationship between in the vehicle longitudinal direction and in the vehicle transverse direction effective, different horizontal spring constants each of the props by the ratio between the latitude and longitude of the associated Influenced support piece.
  • the torsional stiffness (longitudinal stiffness) of the known support can be achieved without significantly influencing the transverse stiffness and the vertical stiffness within optimize a relatively wide range.
  • the known box support is less suitable for a traction vehicle which is designed for driving around bends at a speed which has been substantially increased compared to previously and thus for a correspondingly increased, for example by a factor of 2 to 3, free transverse acceleration of the vehicle body, since the respectively occurring ones
  • Large transverse deflections of the vehicle body with respect to the bogie cannot be limited to an allowable dimension by the spring elements which are relatively soft in the transverse direction.
  • a box support known from FR-A-2 241 437 another type contains a soft spring element in the form a lying, thick-walled rubber tube, which has a longitudinal axial bore and which is fixed between parallel plates.
  • On the top plate is a friction pad for that on it slidably supported part of the rail vehicle attached.
  • the plates are through a rubber tube penetrating vertical socket arrangement led to the Plates of a relative shift in parallel to keep each other and to prevent the Plates are brought out of parallelism.
  • the arrangement of the sockets is thus intended to be lateral Deflection of the spring element can be prevented.
  • the Spring element of this known support is for Transmission of those acting on the box Reset torques not suitable.
  • the invention has for its object a further developed, improved box support of the entrance to create mentioned type, which when driving straight ahead soft cross-adjustment of the suspension allowed and which when high lateral accelerations occur at faster Cornering a harder suspension in the transverse direction Vehicle body and a limitation of the lateral Deflection of the tiltable spring elements enables a value that corresponds to a predetermined, especially for compliance with the clearance profile limiting transverse deflection of the vehicle body opposite corresponds to the bogie.
  • the inventive design of the support achieves a progressive spring characteristic of the support devices in the transverse direction, with in a lower region of the transverse deflection, which corresponds approximately to a range of free transverse acceleration of 0.8 to 1.0 m / sec 2 , which is common in previous designs, essentially the transverse rigidity of the spring elements is effective, while with a further transverse deflection the stop parts arranged within the spring elements each interact with the corresponding guide part and the relatively high rigidity of the elongated support pieces in the transverse direction of the vehicle comes into effect, with corresponding restoring forces on the guide devices Vehicle body can be exercised.
  • the rail vehicle shown e.g. a locomotive for speeds of over 200 km / h when driving straight ahead, and designed for driving through curves with increased speed, contains a vehicle body 1 and two bogies 2, only one of which is shown is.
  • Each bogie 2 contains a bogie frame with side members 3, on which the box 1 via lateral Support devices 4 is supported.
  • the bogie frame is in a known manner via primary springs, not shown supported on the axles of two wheel sets 5 and via a device, not shown, for transmission the tensile and braking forces, e.g. an acquaintance Deep-drawing device, with the box 1 about a vertical axis Z rotatably connected.
  • the wheel sets 5 are on the bogie frame attached drive motors, not shown coupled.
  • Each of the support devices 4 contains two laterally deflectable Spring elements 6 and 6a, as shown in Form of ("Flexicoil” -) coil springs, which in the area the transverse center plane of the bogie 2 between two Spring plates 7 over the side member 3 or one of this inwardly projecting console 3a are arranged.
  • the inner spring elements 6a can also on the Longitudinal beam 3 connecting cross member may be arranged.
  • the Support devices 4 also each contain two pairs of elongated, as shown rail-like support pieces 8 Rubber or a similar rubber-like material, which each between the spring plate 7 and the neighboring Vehicle part - the box 1 or the bogie 2 - transverse are arranged and via which the spring plate 7th can be tilted in the vehicle longitudinal direction X and in the vehicle transverse direction Y are supported.
  • Corresponding support pieces 8 can also formed by sections arranged in a rail-like manner be.
  • the support pieces 8, each in the form of a plan view narrow rectangle can, as shown each with two on their upper and lower ones Support surface vulcanized or glued metallic Stiffening plates 10 may be provided.
  • each of the support devices 4 contains one within one of the spring elements 6 and 6a, as shown the outer spring element 6, arranged telescopic guide device 11, which one with the one spring plate 7 rigidly connected sleeve-like stop part 12 and an insertable in this, with the other spring plate 7 rigid connected, mandrel-like guide part 13 contains.
  • the Ends of the spring element 6 are through the stop part 12 and the guide part 13 centers which parts with each other opposite, tapered end sections 12a and 13a are executed, which are at half the height of the spring element 6 loaded by the box 1 overlap a middle height section V.
  • the spring element 6 surrounds the stop part 12 with a towards the end portion 12a increasing radial outer Game A, which corresponding relative movements of the Stop part 12 and the spring element 6, in particular those that occur when turning the bogie 2 S-shaped deformations of the spring element 6.
  • the end section 12a surrounds the end section 13a of the guide part 13 with a radial inner play B, which corresponding stop-free relative movements of these end sections 12a and 13a, in particular the transverse displacement of the box 1 with respect to the bogie 2 towards the outside of the curve when passing through curves, up to a predetermined maximum value of the lateral acceleration of, for example, 0.8 to 1 m / sec 2 .
  • a predetermined maximum value of the lateral acceleration of, for example, 0.8 to 1 m / sec 2 .
  • the transverse rigidity of the spring elements 6 and 6a and - in series with this - the supporting pieces 8 are essentially effective.
  • the ends of the spring elements 6a are each centered by an insert part 14 which is rigidly connected to the relevant spring plate 7.
  • the guide device 11 When the predetermined value of the transverse force is exceeded, for example when driving through curves at high speed, the guide device 11 becomes effective by the stop part 12 striking against the guide part 13, so that when the box 1 is further deflected exclusively the spring stiffness of the correspondingly wedge-shaped the outside of the curve converging, deformed, in the vehicle transverse direction Y relatively rigid support pieces 8 comes into effect.
  • the diagram shows the course of a through a solid line shown spring characteristic K of executed according to the invention in the manner described Support device 4 when loaded in the transverse direction of the vehicle Y, with over the transverse deflection s in the transverse direction Y effective restoring force F is applied.
  • the diagram also shows three spring characteristics shown in dashed lines K1, K2 and K3 of the two ends of the spring elements 6 and 6a assigned and with these in each case Series deflected support pieces 8, the characteristic K1 that caused by shear stress of a support piece 8 Part D1 corresponds to the transverse deflection.
  • the Characteristic curve D2 corresponds to the sum of the proportions D1 and D2 of the two support pieces 8, while the characteristic curve K3 Sum of the shear stiffness (parts D1 and D2) and the due to the wedge-shaped deformation of this in the transverse direction of the vehicle Y caused correspondingly rigid support pieces 8 Share E in the total transverse deflection of the support device 4 corresponds.
  • the total transverse deflection of the support device 4 thus consists of the individual parts D1, D2 and E and one determined by the inner play B. Share together which of the by the management facility 11 limited deflection of the spring elements 6 and 6a corresponds.
  • a progressive spring characteristic of the support device 4 in the transverse direction Y is achieved in this way, which, when driving straight ahead and when cornering slowly, up to a deflection S1 limited by the internal play B, is caused by the transverse rigidity of the spring elements 6, 6a and Carriers 8 certain, relatively soft suspension guaranteed.
  • a progressive spring characteristic in the transverse direction Y could also be carried out with a design with elastic Cross stops between box 1 and the bogie 2, e.g. through between those described above Stops 17 and 18 arranged, not shown Rubber buffers.
  • Such a facility would have the disadvantage, however, that especially when driving of tight bends, due to the turning movement of the bogie 2 around the vertical axis Z and by translatory Longitudinal movements of the bogie 2, e.g. under traction, very large relative movements in the vehicle longitudinal direction X result in the relevant cross stops 17 and 18. This can cause wear and fatigue problems occur on the rubber buffers and unwanted, the turning and Longitudinal movements of the bogie 2 inhibiting Frictional forces arise.
  • each within the spring element 6 arranged sleeve-like stop part 12 - or the guide part 11 - made of a hard, wear-resistant material be carried out because the elasticity of the support devices 4 in the transverse direction Y not through the stops itself, but through those assigned to the spring ends Carrier pieces 8 is achieved.

Accordingly, a resilient stop achieved between the guide member 13 and the stop member 12. It goes without saying that the stop part 12 also a corresponding, spring-mounted contact piece can be.
