Definitions

  • the invention refers to an axle box suspension for mounting axles of a railway vehicle to a truck frame thereof according to the introductory part of claim 1.
  • FIG. 8 shows its conventional example.
  • numeral 13 denotes a wheel, which is mounted on the same axle 1 as that of a wheel (not shown) provided at the opposite side of the vehicle.
  • Such two axles are mounted in the vicinities of both the ends of a truck frame 12, thereby constructing one truck.
  • Numeral 3 denotes an axle box which contains a bearing 2 and so on of the axle 1.
  • axle box 3 At the right side of the drawing of the axle box 3 is provided an axle anchor rod 3' formed integrally with the axle box, and rotatably slidably supported by a pin 8' wound with a resilient element 7a to the truck frame 12.
  • axle box 3 At the left of the drawing of the axle box 3 is connected one end of a link 11 by a pin 10, and the other end of the link 11 is coupled to the truck frame 12 through the resilient element 7b.
  • Numeral 6 denotes an axle spring, which buffers relative upward and downward movements between the truck frame 12 and the axle 1.
  • An axle anchor rod type axle box suspension shown in Figs. 10 and 11 eliminates a sliding section, in which an axle anchor rod 3' is coupled to a truck frame 12 by a pin 8' wound with a resilient element 7a. Since the axle anchor rod 3' is of a cantilever beam, two sets of resilient elements 7a and pins 8' must be provided as shown in Fig. 11 so as to resist against an external force applied in an axle direction.
  • a bearing supporting resilient element 7c is wound between a bearing 2, the axle box 3 and a bearing retainer 5.
  • the performance required for a recent railway vehicle includes high speed running performance, easiness of maintenance and a reduction in a vehicle weight to reduce a damage imposed on the rails, and so on.
  • This invention is made to solve the above-described problems of the prior art, and an object of the invention is to provide a light-weight axle box suspension which has high running stability at a high speed and a reduction in its maintenance work.
  • an axle box suspension for a railway vehicle comprising an axle box body formed integrally at one side of an axle box with an axle anchor rod and at the other side of a supporting arm, and an axle spring engaged between the axle box body and a truck frame, the axle anchor rod being integrally coupled to the truck frame through a first resilient element, the supporting arm being coupled to the truck frame through a second resilient element in such a manner that the twisting rigidity of the second resilient element as taken axially in the running direction of the vehicle is sufficiently smaller than the composite twisting rigidity of the axle anchor rod and the first resilient element in the same direction.
  • the axle box body is formed integrally with the axle box and the axle anchor rod, and is mounted at the truck frame through the resilient element in such a manner that there is no slide and gap.
  • axle anchor rod allows a twist in the running direction of the vehicle, and is coupled in series with the twisting rigidity of the resilient element , then the composite twisting rigidity between the axle box body and the truck frame is reduced, whereby the relative displacement of rolling between the axle and the truck frame can be easily allowed, so that the axle box and the axle can follow the longitudinal, lateral and vertical vibrations between the axle and the truck frame as a whole without rattling phenomenon.
  • Figs. 2-4 show examples of the sectional views of an axle anchor rod 3'.
  • the twisting rigidity of the axle anchor rod 3' can be selected by suitably setting the sectional shape of the axle anchor rod 3'.
  • Figs. 1 and 5 show an embodiment of the invention.
  • the axle box of this embodiment is provided with a second resilient element 9.
  • An axle box 3 supporting the axle 1 with a wheel 13 is provided with an axle anchor rod 3' and a supporting arm 3'' extending longitudinally in a running direction C of a truck frame 12 to form an axle box body 4.
  • the axle anchor rod 3' is shaft-coupled to an axle anchor rod supporting portion of the truck frame 12 by means of a first resilient element 7' and a shaft 8, and the supporting arm 3'' is coupled to a supporting portion of the truck 12 in such a manner that two second resilient elements 9 are held therebetween.
  • the first resilient element 7' is adhered to the shaft 8, while the second resilient element 9 is formed in a laminated layer structure so that the rigidity thereof in a direction F corresponding to a shearing direction may reduce.
  • the axle 1 is allowed in vertical relative movements in a direction E in the drawings to the truck frame through the axle box body 4.
  • the first resilient element 7' transmits a propulsion force and a brake force in a direction C (same as the running direction of the vehicle) and lateral direction force of the direction D (same as the axle direction) from the axle 1 to the truck frame 12 through the axle box 3 and the axle anchor rod 3', while the second resilient element 9 mainly transmits the lateral force in the direction D.
  • the second resilient element 9 is formed in a laminated layer structure, it can mainly resist against a force applied in a direction D, and rigidity in vertical direction is smaller than that of the axle spring 6 in a direction F.
  • the twisting rigidity of a second resilient element 9 supported by the supporting arm 3'' at the other end of the axle box body 4 is dynamically in parallel with K.
  • this twisting rigidity is designated by K3
  • the composite twisting rigidity can be reduced.
  • Fig. 6 shows a second embodiment of the invention, wherein a second resilient element is adapted.
  • An axle spring 6 is engaged between a truck frame 12 and an axle box 3.
  • the other construction is the same as that of the embodiment shown in Fig. 1.
  • Fig. 7 shows a third embodiment of the invention.
  • a second resilient element 9 interposed between a truck frame 12 and an axle supporting arm 3'' is employed as one set, and the other construction is the same as that of the above embodiment in Fig. 1.
  • an axle box suspension having an axle spring
  • an axle box body is formed by providing an axle anchor rod at one end of the axle box, and the axle anchor rod is shaft-coupled to a truck frame through a resilient element, so that longitudinal, lateral and vertical swivel movement between the axle and the truck frame can be allowed by deforming the resilient element and the axle anchor rod without rattle, thereby the running stability of the vehicle is greatly improved.
  • the axle box suspension does not have slides and gaps, a wear and a deterioration due to years of driving are eliminated, whereby replacement of the components will be obviated and maintenance thereof will be much more facilitated.
  • excellent advantages such as simplified structure, space-saving of the whole axle box suspension, reduction in its weight are provided.
