Definitions
- the invention relates to an axle box suspension for mounting axles of a railway vehicle to a truck frame thereof according to the introductory portion of claim 1.
- FIG. 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. 8 and 9 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. 9 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.
- axle box suspension according to claim 1, and further embodiments are claimed in subclaims 2-4.
- said axle box suspension has an axle anchor rod of selected sectional shape which is integrally coupled to the truck frame through a shaft and a resilient element.
- the axle box body 4 is formed integrally with the axle box 3 and the axle anchor rod 3', and is mounted at the truck frame 12 through the resilient element 7 in such a manner that there is no slide and gap.
- axle anchor rod 3' allows a twist in the running direction of the vehicle, and is coupled in series with the twisting rigidity of the resilient element 7, then the composite twisting rigidity between the axle box body 4 and the truck frame 12 is reduced, whereby the relative displacement of rolling between the axle 1 and the truck frame 12 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.
- An axle anchor rod 3' extending in the same direction as the running direction C of a truck is integrally provided at an axle box 3, which is supporting the axle 1 with a wheel 13, forming an axle box body 4.
- the axle box body 4 is mounted to a truck frame 12 through an axle spring 6, but the axle anchor rod 3' is shaft-coupled by a resilient element 7 and a shaft 8 at the axle anchor rod support of the truck frame 12.
- the resilient element 7 is adhered to the shaft 8 and is force-fitted into the axle anchor rod 3', so that there is no slipping part in this structure.
- the shaft 8 and the truck frame 12 are coupled by a tapered shaft fitting or a bolt clamping which also makes the structure with no slipping parts. Accordingly, the axle box body 4 is allowed to swivel in a direction E around the shaft 8 as a center by means of the deformation of the resilient element 7.
- the axle 1 is allowed in vertical relative movements in a direction F to the truck frame 12 through the axle box body 4.
- the resilient element 7 transmits a propulsion force and a brake force in a direction C (same as the running direction) and lateral force in a 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'.
- a displacement between the axle box body 4 and the truck frame 12 is allowed by means of the deformation of the resilient element 7. Since there is no slip and particularly no gap in a direction C (same as the running direction of the vehicle), the axle box suspension does not rattle, so that running stability is enhanced and the vehicle is enabled to run at high speed. Furthermore, since there is no sliding or slipping parts, the gap is not increased due to aging wear as the conventional one, the deterioration of the running performance can be prevented, so that the replacement of worn components is eliminated, and maintenance can be easily done. As compared with the conventional example, the link and the pins are eliminated, whereby weight of the axle box suspension can be reduced. Further, it is made easy to assemble because of its simple structure.
- the twisting rigidity of the resilient element 7 can be coupled in series with that of the axle anchor rod 3' in the present invention, the twisting rigidity between the axle box body 4 and the truck frame 12 can be reduced.
- Fig. 3 is a sectional view of the axle anchor rod 3'.
- the twisting rigidity of the axle anchor rod in a direction G (same as the running direction) in the drawing is designated by K1 as shown in Fig. 2 and the twisting rigidity of the resilient element 7 in the direction G is designated by K2
- the K1 and the K2 are equalized substantially to the same degree thereby to reduce the composite twisting rigidity K of the K1 and the K2 with good balance without decrease of the strengths of the axle anchor rod 3' and the resilient element 7.
- the relative displacement is allowed in the rolling direction between the axle 1 and the truck frame 12. Therefore, the vehicle can follow the twist of the track due to an irregularity in the track or a reduction in the cant of the rails, thereby preventing the reduction of the wheel load generated by the twist of the rails (if the reduction of the wheel load is increased, derailment will finally be caused).
- Fig. 4 shows a second embodiment of the invention.
- 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 previous embodiment.
- the twisting rigidity of the axle anchor rod 3' is suitably selected by setting its sectional shape in combination with the twisting rigidity of the resilient element 7.
- Figs. 5A and 5B show other examples of the sectional views of an axle anchor rod 3'.
- the twisting rigidity of the axle anchor rod 3' in a direction G in Fig. 3 can be selected by suitably setting the sectional shape of the axle anchor rod 3' as described above.
