Description

  The present invention relates to a trunk receiving device for a railway vehicle connector. Specifically, a coupling end portion of the coupling device is coupled to a railway vehicle or a shock absorber via a joint member, and the coupling end portion serves as a base point. The present invention relates to a case receiving device that supports a swingable coupler by a case receiving member so as to be swingable.

  Railway vehicles are provided with connectors at the front and rear of the vehicle, and a plurality of vehicles are connected to each other by a connector provided in each vehicle. The coupler is swingably coupled to a vehicle or a shock absorber fixed to the vehicle via a predetermined joint member. Therefore, since a plurality of vehicles can be bent at the connecting portion, they can travel safely even if the track is curved. When disconnecting a connected vehicle, a pair of connected couplers are disconnected. At this time, the released coupler is supported by the trunk receiving device so as not to fall and fall down due to its own weight. The case receiving device is fixed to the vehicle body, and supports the body portion of the coupler, that is, the coupling cylinder. However, the coupled coupler oscillates during traveling, and thus does not prevent the coupling from oscillating. Thus, it has a predetermined structure so that the connecting cylinder can be supported while following the connector.

JP-A-8-133080

  Although it is not a direct document of the present invention, Patent Document 1 describes a coupling device and a case receiving device. As shown in the perspective view of FIG. 3A, the connecting device 51 includes a connector 53 having a connecting portion 52, a shock absorber 55 for buffering an impact received by the connector 53, and a connector. 53 and a shock absorber 55 are coupled to each other by two pins so as to be swingable in the horizontal and vertical directions. Although not shown in the figure, the shock absorber 55 is fixed to the vehicle. The connecting cylinder 58 is supported by the trunk receiving device 60 so that the coupler 53 does not fall due to its own weight. The case receiving device 60 includes two case receiving spring boxes 61 and 61, a case receiving beam 62, and a sliding plate 63. The trunk receiving spring box 61 is a rectangular parallelepiped box that is open at the top. The upper part is provided with flanges 65 and 65, and is attached to the vehicle body T 'by bolts or the like not shown in the drawing. As shown in FIG. 3A, a barrel support spring 66 and a suspension bolt 68 penetrating through the barrel support spring 66 are stored in the barrel support spring box 61. Both ends are pressed by the head of the suspension bolt 68, that is, the bottom of the spring holding plate 69 and the case receiving spring box 61. Accordingly, the suspension bolt 68 is urged in the direction of the arrow Y ′. The suspension bolt 68 passes through a cylindrical guide hole 71 opened on the bottom surface of the trunk receiving spring box 61 and protrudes downward. The trunk receiving beam 62 is made of a groove-type steel beam having a predetermined length, and both ends thereof are fixed by suspension bolts 68 and 68 and nuts 72 and 72. That is, the case receiving beam 62 is suspended from the suspension bolts 68 and 68 of the case receiving spring boxes 61 and 61 while being urged in the direction of the arrow Y ′ by the case receiving springs 66 and 66. A sliding plate 63 is provided at the center of the upper surface of the barrel receiving beam 62, and the connecting drum 58 is slidably supported on the sliding plate 63. The coupler 53 can smoothly slide in the horizontal direction on the sliding plate 63, and can move up and down in the vertical direction because the cylinder support springs 66 and 66 extend and the cylinder support beam 62 moves up and down. Therefore, when the connector 53 is connected to another connector and the vehicle travels, the connector 53 can swing without being obstructed by the trunk receiving device 60, and when the connector 53 is disconnected from the other connector. The coupler 53 is supported by the case receiving device 60 without falling.

  Also with the conventionally known case receiving device 60, the swing of the coupler 53 is not hindered when the vehicle is connected and traveled, and the coupler 53 can be prevented from dropping when the coupler 53 is disconnected. However, there are some points that should be improved. For example, when a relatively heavy coupler is provided, it is necessary to increase the spring force of the trunk receiving springs 66 and 66. That is, since it is necessary to increase the spring constant, the body receiving springs 66 and 66 are enlarged. When the spring force of the trunk receiving springs 66, 66 becomes strong, the reaction force received by the coupler from the trunk receiving springs 66, 66 when the coupler swings downward increases the load on the trunk receiving device 60. It takes. If it does so, it will be necessary to raise the intensity | strength of each member and periphery member of the trunk | drum receiving apparatus 60 so that it can endure a load, a member will enlarge, and an apparatus will become expensive. Furthermore, when the spring constant increases, there is a problem that the followability to the swing of the coupler 53 is impaired. The connected coupler 53 is bent according to the state of the track when the vehicle is traveling, but the followability is impaired, and an excessive load is applied to the member of the connecting device 51, for example, the joint member 56, or noise is generated. It can also be a cause. There is also a problem of attachment of the trunk receiving device 60 to the vehicle body T '. When supporting the coupler, an initial reaction force is applied to the case receiving springs 66, 66, but in order to obtain an initial reaction force, the previously selected longer case receiving springs 66, 66 are compressed. It is necessary to store in the trunk receiving spring box 61, and it is difficult to attach the member having the reaction force to the vehicle body T ′. Furthermore, the spring has a problem of resonance.

  An object of the present invention is to provide a case receiving device that solves the above-described conventional problems or problems. Specifically, a coupler that is easy to attach to a vehicle body and has a relatively heavy weight is provided. Even if it is supported, it does not require a large case receiving device or peripheral members, and thus can be provided at a low cost, with sufficient followability to the swing of the coupler, and an excessive load on the members of the coupling device. Another object of the present invention is to provide a case receiving device that does not generate any noise or noise and that does not resonate and does not apply an excessive load to the entire device.

  In order to achieve the above object, the present invention is configured such that a case receiving member that supports a connecting cylinder of a connector is supported by a damper device. That is, the invention according to claim 1 is that a coupler for a railway vehicle coupled to a railway vehicle or a shock absorber via a joint member is formed in a vertical direction and a left and right direction around the end of the coupler by a trunk receiving member. A trunk receiving apparatus that is swingably supported in a direction, wherein the trunk receiving member is configured to be supported by a frame body of the railway vehicle by a damper apparatus. According to a second aspect of the present invention, in the trunk receiving device according to the first aspect, the damper device includes two damper devices, and the two cylindrical damper members are disposed in the vicinity of both ends in the longitudinal direction. The connector is configured to be supported by the case receiving member at a substantially central portion in the longitudinal direction of the case receiving member, and the invention according to claim 3 is described in claim 1 or 2. In this case, the damper device includes a cylinder, a piston having an outer diameter smaller than the inner diameter of the cylinder by a predetermined amount, and a compressible viscous fluid filled in the cylinder.

  As described above, according to the present invention, the cylinder support member that supports the coupling cylinder of the coupler is configured to be supported by the damper device, so that it can sufficiently follow the oscillation of the coupler and is separated. The connected coupler can be supported so as not to fall. In addition, although the reaction force of the spring increases in proportion to the magnitude of the displacement, the damper device maintains a relatively constant reaction force regardless of the magnitude of the displacement, so an excessive reaction force is generated. There is no such thing as a burden on the case receiving device. Therefore, it is not necessary to reinforce the peripheral members of the case receiving device, and the device can be reduced in size and provided at a low cost. Since the damper device attenuates the vibration, the coupler does not resonate due to the vibration generated when the vehicle travels, and an excessive load is not applied to the case receiving device. Furthermore, the damper device is easy to install. According to the second aspect of the present invention, the case receiving member is configured so that the end portions near both ends in the longitudinal direction are supported by the two damper devices, and the connecting cylinder is supported in the central portion. The member itself bends slightly. That is, since the coupler is supported elastically, it has excellent followability with respect to the swinging of the coupler. Furthermore, according to the invention described in claim 3, the damper device includes a cylinder, a piston having an outer diameter smaller than the inner diameter of the cylinder by a predetermined amount, and a compressible viscous fluid filled in the cylinder. The fluid in the cylinder not only flows through the gap between the cylinder and the piston, but also has an elastic force. That is, vibration can be suppressed while elastically supporting the coupler. Therefore, since the coupler can be supported with good followability, an effect peculiar to the present invention that noise is not generated can be obtained.

  Embodiments of the present invention will be described below. A perspective view of FIG. 1A shows a case receiving device 1 and a connecting device 2 according to the present embodiment. As is well known in the art, the coupling device 2 couples the coupler 4 coupled to the coupler of another vehicle, the shock absorber 5 that absorbs shock received by the coupler 4, and the coupler 4 and the shock absorber 5. A joint member 6. The connector 4 includes a connector body 8 having a predetermined thickness and a connection portion 9 connected to another connector. The connection portion 9 is fixed to one end of the connector body 8, and the other A bifurcated coupling end 10 is formed at the end. A connecting cylinder 12 having a flat bottom surface is formed at the center lower portion of the connector main body 8, and the connector 4 is slidably supported by the receiving apparatus 1 in the connecting cylinder 12. The shock absorber 5 includes a plurality of shock absorbers 14 made of an elastic material such as rubber, front and rear companion plates 15 and 16 sandwiching the shock absorbers 14 from front and rear, and front and rear companion plates 15 and 16 from the front and rear. The shock absorber frame 17. The shock absorber frame 17 is formed with a bifurcated coupling end 18. The coupler 4 and the shock absorber 5 are coupled by a joint member 6. Specifically, a predetermined portion of the joint member 6 is inserted into the fork of the coupling end 10 of the coupler 4 and coupled by the horizontal pin 20, and the joint of the joint member 6 is coupled to the fork of the coupling end 18 of the shock absorber 5. Other parts are inserted and connected by vertical pins 21. Therefore, the coupler 4 is coupled to the shock absorber 5 so as to be able to swing in both the horizontal direction and the vertical direction.

  Although not shown in the drawing, a predetermined table is fixed to the vehicle body T, and the shock absorber 5 is placed on the table so as to be slidable in the axial direction of the coupling device 2. A pair of brackets are also fixed to the vehicle body T and restrict the movement of the front and rear accompanying plates 15 and 16. That is, the front companion plate 15 can be pushed backward against the elastic force of the buffer body 14, but the forward movement is restricted by one bracket, and the rear companion plate 16 Although it can be pushed forward against the elastic force, the backward movement is restricted by the other bracket. When the coupler 4 is pushed or pulled with a strong force, the shock absorber frame 17 is pushed back and forth in the axial direction of the coupling device 2. Then, one of the front and rear companion plates 15 and 16 is pushed by the shock absorber frame 17, and the shock absorber 14 sandwiched between the front and rear companion plates 15 and 16 is compressed. Thus, force is transmitted to the vehicle body T. Since the force is not transmitted directly but indirectly through the buffer body 14, the impact is absorbed.

  The case receiving device 1 is supported by a case receiving frame 24 attached to the vehicle body T and supporting the device itself, two dampers 26 and 26 fixed to the case receiving frame 24, and dampers 26 and 26. It comprises a cylinder support member that slidably supports the connecting cylinder 12, that is, a sliding plate 28. The case receiving frame 24 is formed by bending a long and narrow steel plate having a predetermined width, and the side surface has a wide rectangular shape with the upper side cut off. In addition, flanges 29 and 29 bent inward are provided at portions corresponding to the upper side of the two short sides of the rectangle, and the flanges 29 and 29 are fixed to the vehicle body T by bolts. Two dampers 26 and 26 are placed apart from each other on the inner side of the case receiving frame 24, that is, the long side of the rectangle, and are fixed by bolts or welded.

As shown in the cross-sectional view of FIG. 1A, the damper 26 includes a cylinder 31 fixed to the case receiving frame 24 on the bottom surface, a piston 32 provided in the cylinder 31, and a piston 32. The piston rod 33 is fixed to the cylinder 31 and the buffer fluid 35 is filled in the cylinder 31. The inside of the cylinder 31 is divided into two chambers consisting of an upper chamber 36 and a lower chamber 37 by a piston 32. Since the outer diameter of the piston 32 is slightly smaller than the inner diameter of the cylinder 31, the piston 32 and the cylinder 31 are separated. The upper chamber 36 and the lower chamber 37 communicate with each other through a predetermined gap 39 formed between the inner walls. The buffer fluid 35 is made of a viscous fluid having compressibility such as an elastomer. Examples of such viscous fluid having compressibility include dimethyl silicone oil, phenylmethyl silicone oil, fluorocarbon, and silicone oils represented by chemical formulas nC ₇ H ₁₆ and nC ₁₂ H _26. Etc. While the force acting on the piston 32 is relatively small, the buffer fluid 35 does not flow through the gap 39. However, when a predetermined load is applied to the piston rod 33 and a sufficient force is applied to the piston 32, the buffer fluid 35 Then, it flows through the gap 39 and flows from one chamber of the upper and lower chambers 36 and 37 to the other chamber.

  The sliding plate 28 is made of an elongated steel plate having a predetermined thickness and a predetermined width. Through holes are formed in the vicinity of both ends of the sliding plate 28, piston rods 33, 33 are inserted, and are fixed to the piston rods 33, 33 by nuts 40, 40. That is, the sliding plate 28 is supported by the dampers 26 and 26 in the vicinity of the end portions at both ends. The connecting cylinder 12 of the connector 4 is slidably mounted on the center portion of the sliding plate 28.

  The operation of the trunk receiver 1 according to the present embodiment will be described. When the connector 4 is connected and the vehicle travels, the two vehicles are bent at the connected portion. At this time, the coupler 4 swings in the vertical direction and the horizontal direction according to the curve of the track, with the coupling end 10 as a base point. Even when the coupler 4 is disconnected, the coupler 4 swings up and down by its own weight or in response to the vibration of the vehicle. When the connector 4 swings in the left-right direction, it slides smoothly on the sliding plate 28 to the left and right, as in a conventionally known case receiving device. When the coupler 4 swings downward, a force in the arrow Y direction is applied to the piston 32 via the piston rod 33 via the sliding plate 28, and the piston 32 is pushed downward. Then, the buffer fluid 35 in the lower chamber 37 is pushed by the piston 32 and compressed. When the amount of displacement by which the piston 32 is pushed down is relatively small, the force is also small, elastic energy is stored in the buffer fluid 35, and the position of the piston 32 is restored when the force is released. An effect similar to that of a conventionally known barrel receiving spring can be obtained. When the displacement amount by which the piston 32 is pushed down is relatively large, the force by which the piston 32 is pushed down is also large. In this case, after the buffer fluid 35 is compressed, it flows through the gap 39 and flows from the lower chamber 37 to the upper chamber 36. Since the buffer fluid 35 has a viscosity, resistance is generated when it flows through the gap 39 and energy is consumed. If it does so, the force by which piston 32 is pushed down will be relieved. When the coupler 4 swings upward, the force in the direction of arrow Y applied to the sliding plate 28 is reduced. Then, the compressed buffer fluid 35 in the lower chamber 37 is expanded, and the sliding plate 28 is pushed upward. The buffer fluid 35 in the upper chamber 36 also flows into the lower chamber 37 via the gap 39.

  The vertical swing of the coupler 4 is also absorbed by the deflection of the sliding plate 28. The sliding plate 28 is supported near the ends at both ends, and supports the connecting cylinder 12 at the center. Therefore, the center is slightly bent. When the magnitude of the swing of the coupler 4 is relatively small, the amount of deflection slightly changes, and the vertical swing of the coupler 4 can be absorbed.

  The graph of FIG. 2 shows the amount of downward displacement of the trunk support member and the coupler for the trunk receiver 1 according to the present embodiment, that is, the trunk receiver 1 in which the trunk support member is supported by the dampers 26 and 26. The relationship of the load which a trunk receiving member receives from is shown. For comparison, a similar relationship is also shown for a conventionally known case receiving device, ie, a case receiving device in which a case receiving beam is supported by a case receiving spring. In the conventional well-known case receiving device, when the displacement amount is large, that is, when the swinging amount of the coupler is large, the load applied to the case receiving beam becomes large, but in the case receiving device 1 according to the present embodiment, Even if the amount of displacement increases, the load applied to the sliding plate 28 does not increase so much. Therefore, in the case receiving apparatus 1 according to the present embodiment, an excessive load is not generated in the case receiving apparatus 1 even if the swing amount of the coupler 4 is large.

  The case receiving device according to the present invention is not limited to the above embodiment, and can be implemented in various forms. For example, the case receiving member is described as being constituted by a plate-shaped sliding plate 28, but the cross-sectional shape is constituted by a U-shaped member, for example, a case receiving beam made of a grooved steel beam. Can be supported by a damper, and a sliding plate can be provided on the cylinder support beam to support the connecting cylinder. In this case, the case receiving member has sufficient strength, so that even a relatively heavy coupler can be supported. Further, it is obvious that the number of dampers is not limited to two, and can be implemented by one or three or more. In addition, the case receiving device according to the present invention has been described as applied to a connector coupled to a shock absorber, but can also be applied to a coupling device directly coupled to a vehicle.
