In addition, it is equipped with a trunk support beam attached to the vehicle body side. Therefore, the connector 61 can be moved in the horizontal direction in the unconnected state. For this reason, the connecting operation is performed by the operator manually aligning the connector 61 with the center. In addition, when the connecting device, the shock absorber, and the case receiving device are integrated with each other, the conventional connecting device is required to be attached and detached individually with the connecting device, the shock absorber, and the case receiving device. However, there is a technical problem of requiring labor and time for work.

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
The railcar coupling device includes a coupler 1, a shock absorbing shock absorber 2, a swinging mechanism 4, and a telescopic portion that can be connected to a connected vehicle in order from the front end side (front end side). 3 and a body receiving / recentering device 9 are integrally provided to form an integral type. The connector 1 and the shock absorbing cushioning device 2, connecting the flange portion with fastening gold 24 of split. The shock absorbing buffer device 2 and the shock absorber 3 are coupled to be swingable at least in the horizontal and vertical directions by a swing mechanism 4 so that the coupler 1 can swing relative to the vehicle body 6. Since the connector 1 can be mounted with either the close contact connector 1a shown in FIG. 1 or the semi-permanent connector 1b shown in FIG. 3, only the connector 1 at the tip is changed, so that it can be used properly according to the vehicle. can do.

  The shock absorbing shock absorber 2 is a device in which the shock absorbing member absorbs the shock force transmitted from the coupler 1 by plastic deformation in an emergency when the vehicle collides with an obstacle such as a car. Can be used.

  The shock absorber 3 absorbs positive and negative accelerations during acceleration / deceleration of the vehicle, prevents the generation of impact force and improves the ride comfort, and will be described later on the rear side (tail side) of the shock absorption buffer device 2. It is provided with a rocking mechanism 4 interposed therebetween. The shock absorber 3 has a function similar to that of the existing one in that it absorbs positive and negative inputs, and includes a housing frame member 13, a U-shaped action member 14, and a pair of rubber pads that are elastic expansion and contraction portions. Solids 15 and 16 are included.

The housing frame member 13 is assembled so as to form a bottomed cylindrical shape, and includes a bottom portion 13a of the tail portion and an abutting portion 13b provided inside the tip portion on the opening side. A mounting portion 13c at the tail end of the housing frame member 13 of the shock absorber 3 is attached to the vehicle body 6 by tightening bolts 20 , 20 ,. Therefore, the attachment / detachment of the coupling device to / from the vehicle body 6 can be handled only by attaching / detaching the bolts 20 , 20 ,. As shown in FIG. 1C, the action member 14 has a cylindrical upper and lower portions that are slidable in the front and rear directions inside the accommodation frame member 13, and a tail bottom 14a (action part) and the accommodation frame member. A pair of rubber pad assemblies 15 is sandwiched between the bottom portion 13a and the bottom portion 13a by applying an initial pressure, and a set of rubber pad assemblies is provided between the bottom portion 14a (acting portion) and the contact portion 13b of the housing frame member 13. The solid 16 is sandwiched by applying an initial pressure. Further, the distal end portion of the action member 14 forms bifurcated portions 14c and 14c .

The swing mechanism 4 is provided by connecting a rear protrusion 2a of the shock absorbing buffer device 2 serving as a member on the connector 1 side and a front bifurcated portion 14c , 14c of the action member 14. For this reason, the swinging mechanism 4 has a vertical pin 8 and a spherical plain bearing 7 as shown in FIGS. The vertical pin 8 is fitted into the bifurcated portions 14c and 14c and the protruding portion 2a so that the shock absorbing buffer device 2 and the connector 1 can swing left and right. The spherical plain bearing 7 has a spherical surface on the outer surface serving as a bearing surface, and has vertical through holes. In a state where a spherical seat 25 having a multiple split type (divided) concave spherical surface is in close contact with the bearing surface of the spherical plain bearing 7, it is inserted into the cylindrical space 2aA of the protruding portion 2a of the shock absorbing buffer device 2, The spherical seat 25 is fixed to the protruding portion 2a by the annular step surface 2b and the retaining ring 29, and the spherical plain bearing 7 is held on the spherical seat 25 so as to be slidable. Accordance connexion, spherical plain bearings 7 is received in an annular portion of the projecting portion 2a, and is held via a spherical seat 25 which constitutes the cylindrical face the outer peripheral surface is not short. The projecting portion 2a and the spherical seat 25 of the shock absorbing shock absorber 2 constitute a holding portion that holds the single spherical plain bearing 7 so that it can not move back and forth.

The projecting portion 2a of the shock absorbing shock absorber 2 is loosely inserted into the bifurcated portions 14c and 14c of the action member 14 with a predetermined gap, and the vertical pin 8 in the vertical direction (perpendicular to the central axis of the connecting device) is bifurcated. The pair of pin holes 14c and 14c are inserted into the through hole 7a of the spherical plain bearing 7 to be connected. Therefore, the spherical plain bearing 7 is located between the forked portions 14c and 14c. The vertical pins 8 are detachably fixed to the bifurcated portions 14c and 14c by press-fitting or other means. The protrusion 2a of the shock absorbing buffer 2 can be relatively rotated within a predetermined angle range until the protrusion 2a contacts the inner surface (or the vertical pin 8) of the bifurcated portions 14c , 14c . The bifurcated portions 14c and 14c and the vertical pin 8 constitute a holding portion that holds the single spherical plain bearing 7 so that it can not move back and forth. If the vertical pin 8 is press-fitted and fixed in the through hole 7a of the spherical plain bearing 7, the position of the spherical plain bearing 7 with respect to the bifurcated portions 14c and 14c is fixed.

  Thus, when a positive / negative input is transmitted from the coupler 1 to the action member 14 via the shock absorbing buffer device 2, this is buffered by the buffer 3 and transmitted to the vehicle body 6. Therefore, the action member 14 can be elastically moved in both the front and rear directions with respect to the housing frame member 13 of the shock absorber 3 and the vehicle from the neutral state shown in the figure. Thus, the shock absorber 3 incorporates expansion / contraction portions (15, 16) in the housing frame member 13 for buffering the swinging motion of the vehicle body 6 in the front-rear direction.

  That is, the normal compressive force transmitted from the coupler 1 is transmitted to the action member 14 via the shock absorbing buffer device 2 and the swing mechanism 4, and the action member 14 slides rearward in the housing frame member 13. The rubber pad assembly 15 on the rear side is compressed by the bottom portion 14a of the action member 14 and the bottom portion 13a of the accommodation frame member 13, while the action member 14 is accommodated in the accommodation frame member 13 when a normal tensile force is applied. The front rubber pad assembly 16 is compressed by the bottom portion 14 a of the action member 14 and the contact portion 13 b of the housing frame member 13. In this way, the compressive force and tensile force (impact force generated between the vehicles that normally travel) transmitted through the coupler 1 are absorbed, relaxed, and transmitted.

As shown in FIGS. 1C and 2 , the case receiving / recentering device 9 is positioned below the coupling device, and the shock absorbing buffer device 2 and the shock absorber 3 with the swing mechanism 4 interposed therebetween. A pair of elastic devices 9a , 9a having the same function and extending in the direction of the central axis of the connecting device when not connected are provided in parallel. That is, the elastic devices 9a and 9a having the tail end portion swingably coupled to the housing frame member 13 and the tip end portion swingably coupled to the bracket portion 2c which is a member on the coupler 1 side are shown in FIG. As can be seen, they are provided on the left and right sides of the central axis of the shock absorber 3 in plan view. Each elastic device 9a , 9a is constituted by a cylinder device incorporating a metal spring such as a coil spring or an elastic member such as rubber, and has at least an elastic restoring action to return to the neutral position. It is attached to the bracket portion 2c which is a member on the connector 1 side and the attachment portion 13c of the housing frame member 13 of the shock absorber 3 by means of bolts 33 and 33 and nuts 32 and 32 , respectively. Specifically, as shown in the lower half of FIG. 2, the elastic device 9a incorporates elastic members 9c and 9d that apply an initial pressure to both sides of the piston 9b, and the front elastic member 9c is compressed and contracted during expansion. Sometimes the rear elastic member 9d is compressed. It is desirable that the trunk receiving / recentering device 9 has a damper function, and a damper using hydraulic pressure, air, elastomer, or the like can be combined.

Accordingly, the elastic devices 9a , 9a of the case receiving / recentering device 9 are attached to the left and right sides of the vertical pin 8 and the spherical plain bearing 7 and function to hold the unconnected connecting device at the horizontal center position. To do. Each elastic device 9 a , 9 a has a pair of elastic members 9 c, 9 d in the same manner as the arrangement of the rubber pad assemblies 15, 16 of the shock absorber 3, and can expand and contract following the expansion / contraction operation of the shock absorber 3. Of course, the case receiving / recentering device 9 can be disposed above the connecting device. In addition, even if the shock absorbing buffer 2 is omitted from the coupling device, the present invention can be implemented . In this case, the bracket portion 2 c attached to the shock absorbing buffer device 2 is fixed to the coupler 1, and the protruding portion 2 a is formed in the coupler 1. Therefore, the protrusion 2a is a member on the connector 1 side together with the bracket 2c.

Next, the operation of the first embodiment will be described.
When a compressive impact force is applied during normal traveling of the vehicle, the compressive impact force is propagated to the connector 1 of the host vehicle via a connector (not shown) of the connected vehicle. At that time, the compressive impact force acts on the action member 14 of the shock absorber 3 via the shock absorbing buffer device 2 and the swing mechanism 4 (the spherical plain bearing 7 and the vertical pin 8), and the rubber pad assembly 15 is moved as described above. It is compressed and absorbs impact force. After absorbing the compression impact force, the rubber pad assembly 15 returns to its original neutral position by the elastic restoring force.

On the other hand, when a tensile impact force acts on the coupler 1 during normal driving of the vehicle, the tensile impact force propagates to the coupler 1 of the host vehicle via the coupler (not shown) of the coupled vehicle. . At that time, the tensile impact force acts on the action member 14 of the shock absorber 3 via the shock absorbing buffer device 2 and the swing mechanism 4 (the spherical plain bearing 7 and the vertical pin 8), and the rubber pad assembly 16 is moved as described above. It is compressed and absorbs impact force. After absorbing the compression impact force, the rubber pad assembly 16 returns to its original neutral position by the elastic restoring force. Thus, during normal driving in a connected state, the shock absorber 3 cushions back and forth shaking, improving ride comfort. When the rubber pad assemblies 15 and 16 of the shock absorber 3 are compressed, the pair of elastic devices 9a and 9a also appropriately expand or contract. When the vehicle collides with an obstacle such as a car, the shock cannot be absorbed by the shock absorber 3 alone, so the shock absorbing shock absorber 2 is plastically deformed to absorb the impact force.

Then, the vertical swing and the horizontal swing of the coupler 1 and the shock absorbing buffer 2 with respect to the shock absorber 3 are both allowed by sliding between the spherical plain bearing 7 and the spherical seat 25. The In addition, the spherical plain bearing 7 allows the rotation in the rotational direction around the central axis between the coupler 1 and the shock absorbing shock absorber 2 and the shock absorber 3, that is, torsion freely. At that time, the pair of elastic devices 9a and 9a also expand or contract appropriately. Since the swing direction of rotation by connexion connector 1 to the spherical plain bearing 7 is allowed, exceptionally the gap between the sliding gap or vertical pin 8 of the spherical sliding bearing 7 and the spherical seat 25 There is no need to secure large. Shock absorbing cushioning device 2 of the projecting portion 2a and the forked portion 14c of the working member 14, the relative rotation between the 14c, forked portion 14c, the inner surface of the 14c of the projecting portion 2a of the shock absorbing cushioning device 2 acting member 14 Or it is possible in the predetermined angle range until it contacts the vertical pin 8.

The swing of the coupler 1 in the rotational direction is such that the spherical sliding bearing 7 is received by the projecting portion 2a of the shock absorbing shock absorber 2 integrated with the coupler 1, and this is installed in the forked portions 14c and 14c of the shock absorber 3. Thus, the conventional coupler 1, the shock absorbing shock absorber 2 and the shock absorber 3 can be made without greatly changing the design , and can be swung in a free direction including rotation and can be applied to a normal railway vehicle. Therefore, the application of the spherical plain bearing 7 has not only a reduction in the number of parts, but also a significant effect in improving the work efficiency of assembly / disassembly. If the vertical pin 8 is removed from the bifurcated portions 14c and 14c of the action member 14 and the retaining ring 29 is removed from the protruding portion 2a, the spherical seat 25 and the spherical plain bearing 7 can be removed.

When such a connecting device is in a disconnected state, the coupler 1 and the shock absorbing buffer device 2 move in any of the horizontal, vertical or torsional directions with the swing mechanism 4 as a fulcrum. The pair of elastic devices 9a and 9a expands and contracts and returns to the original position by the reaction force of the deformed elastic devices 9a and 9a , so that the connecting device returns to the horizontal / center position.

  6 and 7 show a second embodiment of the present invention, and the same reference numerals are given to the same functional parts as those in the first embodiment. In the second embodiment, the position of the swing mechanism 4 (vertical pin 8 and spherical plain bearing 7) and the structure of the case receiving / recentering device 9 are different from those in the first embodiment. That is, the case receiving / recentering device 9 is functionally separated into the case receiving device 40 and the centering device 41, and the swing mechanism 4 is disposed between the rubber cushioning device 3 and the anchorage 42, and the anchorage. 42 is attached to the vehicle body 6 (shown in FIG. 1) by tightening bolts. 42c is a bolt hole of the anchorage 42.

  In other words, this railway vehicle coupling device includes a coupler 1, an impact absorbing shock absorber 2, a shock absorber 3, a swing mechanism 4, and an anchorage 42 in order from the front end side, and further includes a trunk receiving device 40 and a retraction device 41. It is provided integrally and is an integral type. That is, the tail portion of the coupler 1 and the shock absorbing buffer device 2 are integrated, the shock absorbing buffer device 2 and the shock absorber 3 are integrally connected, and the shock absorber 3 is connected via the swing mechanism 4. By attaching the shock absorber 3 to the vehicle body and elastically supporting the shock absorber 3 by the trunk receiving device 40 and the retraction device 41, an integrated connecting device is configured. Therefore, the attachment / detachment of the connecting device to / from the vehicle body can be handled only by attaching / detaching the bolt of the anchorage 42. The shock absorbing shock absorber 2 also has a function as the two-part clamp 24 in the first embodiment, and includes the coupler 1 (plastic deformation portion thereof) and the action member 44 (described later) of the shock absorber 3. The plastic deformation portion of

  The shock absorber 3 has the same function as that of the existing one in that the positive and negative inputs are buffered, and includes a housing frame member 43, an action member 44, and a pair of rubber pad assemblies 15 and 16. The housing frame member 43 and the coupler 1 are integrated in a normal traveling state.

  The housing frame member 43 is assembled so as to have a bottomed cylindrical shape as in the first embodiment, and includes a bottom portion 43a of the tail portion and an abutting portion 43b provided inside the distal end on the opening side. A swing mechanism 4 similar to that of the first embodiment is formed between the protruding portion 43 c at the tail end of the housing frame member 43 of the shock absorber 3 and the bifurcated portion 42 b of the anchorage 42. That is, the spherical plain bearing 7 and the spherical seat 25 are provided in the protrusion 43c.

The action member 44 has two extending portions 44b and 44b extending rearward from the bottom portion 44a of the front portion, and has a U-shape, and the two extending portions 44b and 44b are disposed in the front and rear of the housing frame member 43. slidably decorated, extending portion 44b, acting portion 44c on the rear end portion of 44b is provided integrally. A set of rubber pad assemblies 15 is sandwiched between the action portion 44 c of the action member 44 and the bottom portion 43 a of the housing frame member 43 by applying an initial pressure, and the contact portion 43 b between the action portion 44 c and the housing frame member 43. A pair of rubber pad assemblies 16 are sandwiched by applying an initial pressure therebetween. The bottom 44a at the tip of the action member 44 is fixed to the tail of the shock absorbing buffer 2 so that the shock absorbing member 2 absorbs the shock force transmitted from the coupler 1 by plastic deformation.

  When a positive / negative input is transmitted from the coupler 1 to the action member 44 via the shock absorbing buffer device 2, this is buffered by the shock absorber 3, and then the anchorage 42 and the vehicle body 6 (shown in FIG. 1) via the swing mechanism 4. ). Accordingly, the action member 44 can be elastically moved in both the front and rear directions with respect to the housing frame member 43 of the shock absorber 3 and the vehicle from the neutral state shown in the figure.

  That is, the normal compressive force propagated from the coupler 1 is transmitted to the action member 44 via the shock absorbing buffer device 2, and the action member 44 slides backward in the housing frame member 43, and the action member 44. The rubber pad assembly 15 on the rear side is compressed by the action portion 44c and the bottom portion 43a of the housing frame member 43. On the other hand, when a normal tensile force is applied, the action member 44 moves forward in the housing frame member 43. The rubber pad assembly 16 on the front side is compressed by the action part 44 c of the action member 44 and the contact part 43 b of the housing frame member 43. In this way, the compressive force and tensile force (impact force generated between vehicles that normally travel) that are propagated through the coupler 1 are absorbed, relaxed, and transmitted to the vehicle body. Yes.

The case receiving device 40 and the retraction device 41 will be described with reference to FIGS . 6 and 7 . The trunk receiving device 40 is provided above the shock absorber 3 and includes a U-shaped support metal 45, and a trunk receiving beam 46 a and a spring box 46 b fixed to the lower portion of the housing frame member 43 of the shock absorber 3. The support body 45 is made of, for example, spring steel, and the central portion is attached to the upper surface of the anchorage 42 by a pin 47 and is preferably swingable. The pin 47 can be shared by extending the vertical pin 8 of the swing mechanism 4. Then, by connexion connected to the bolt 50 and nut 51 between the spring box 46b of both ends of the cylinder receiving beam 46a which is attached by orthogonal to the central axis in the lower part and the both ends of the supporting metal 45 of the housing frame member 43 The housing frame member 43 is elastically supported so as to move up and down via a coil spring in the spring box 46b. Thus, the trunk receiving device 40 is mounted in an erected state between the anchorage 42 and the shock absorber 3 with the swing mechanism 4 interposed therebetween, and elastically supports the shock absorber 3 with respect to the anchorage 42 and thus the vehicle body 6. Yes. The trunk receiving beam 46 a and the spring box 46 b are the same as the known structure except that the trunk receiving beam 46 a is fixed to the lower part of the housing frame member 43. Since the lateral movement and the torsional movement of the housing frame member 43 can be absorbed by elastic deformation of the bolt 50 or the support metal 45, the case receiving beam 46a is fixed to the storage frame member 43, and the support metal 45 can be fixed to the anchorage 42 and supported.

As shown in FIGS. 6C and 7, the rewinding device 41 includes a bracket 52 fixed on the lower surface of the tail end portion (flange portion) of the housing frame member 43 of the shock absorber 3 and a pair of attachment portions of the anchorage 42. 53 and 53, and a pair of elastic devices 54 and 54 having the same function of clamping the bracket 52 from both left and right sides with an initial pressure. Each elastic device 54 has a built-in elastic member 54b such as a metal spring such as a coil spring or rubber initially compressed so as to press the bracket 52 as shown in the lower half of FIG. The pins 54a and 54a pressed press the bracket 52 from both the left and right sides.

Accordingly, the case receiving device 40 is mounted across the swing mechanism 4 and holds the connecting device in a horizontal position in an unconnected state. In the rewinding device 41, each elastic device 54 has at least an elastic restoring force, and elastically maintains the shock absorber 3 and thus the coupler in the center position in an unconnected state. Each elastic device 54 , 54 of the rewinding device 41 can be provided with a damper function by combining a damper using hydraulic pressure, air or elastomer.

  When the connecting device moves in any of the horizontal, vertical or twist directions, the case receiving device 40 and the retraction device 41 function, and the connecting device returns to the horizontal / center position. When the connecting device moves in the vertical direction and when it moves in the torsional direction, the case receiving device main body 46 is elastically supported, so that it is connected in an unconnected state mainly by the elastic force of the case receiving device main body 46. The device returns to the horizontal position. Further, when the connecting device moves in the horizontal direction, one of the elastic devices 54 of the rewinding device 41 is elastically compressed and deformed, so that the connecting device is connected by the elastic force of the elastic device 54 in a non-connected state. The device returns to the center position. Therefore, according to the second embodiment, the same operation as that of the first embodiment can be obtained.

However, if the coupler 1 moves in the horizontal or torsional direction with the support metal 45 fixed to the anchorage 42, the support metal 45 or the bolts 50 , 50 ,. Further, when the coupler 1 moves in the vertical or twist direction, the pin 54 a slightly slides with respect to the bracket 52.
