The present invention relates to a joint joint device for a railway vehicle, and more particularly, a joint joint of a railway vehicle capable of smoothly cushioning shocks coming from the connecting portion as well as smooth refraction when passing between the curved sections and at the same time. Relates to a device.

In general, the joint vehicle of the railway vehicle is articulated with respect to the rotational movement generated between two vehicles when passing through the vehicle curve using an articulated cone as shown in FIG. 1. By rotating around the center pin of the cone, the two vehicles can be configured to pass through the curve smoothly.

Such a connection method of the joint vehicle has a problem that the cost is increased by the size of the device at the same time as the connection portion is large.

The articulated cone is refracted without any interference when the center pin is inserted into and fixed through the upper side and is bent to the left and right sides.

In addition, the difference in the curvature for the difference between the upper and lower heights is formed to buffer the height using a circular ply rubber plate formed on the circumferential surface side of the center pin.

As the conventional articulated vehicle connection method configured as described above, the articulated cone method not only increases the cost because the connection part is largely formed, but also has a circular ply rubber plate mounted inside to damage the circular ply rubber plate from the outside during daily inspection. There is a maintenance problem that cannot be determined.

Therefore, the present invention has been created in view of the above-described conventional problems, and its purpose is to smoothly cushion the impact coming from the connection portion as well as smooth refraction during the passage of the curved section and towing the vehicle. In addition, it is possible to easily identify the damage of the disk-shaped laminated rubber part from the outside, and to provide a joint device of a railway vehicle which improves maintainability.

In order to achieve the above object, the connection articulator device of the railway vehicle of the present invention, the a-type housing having a through-hole, the coupling arm having a fixing arm formed on both sides of the left and right through the through-hole of the a-shaped housing And a pair of disc-shaped laminated rubber parts having a fitting hole formed therebetween, and being fitted into and fitted into the fitting holes of the disc-shaped laminated rubber parts, the a-shaped housing and the engaging part The fixed arm part has a projection fitting part protruding to one side and a circular pushing surface so as to be inserted and fixed at both sides by a long bolt and a nut, and a pair of fixing pin parts having holes formed at the center thereof.

With reference to the accompanying drawings, the joint joint device of the railway vehicle of the present invention configured as described above will be described in detail as follows.

The joint joint device of the railway vehicle of the present invention is mounted on a vehicle located at the front side or the rear side shown in FIG. 2, and the a-shaped housing 40 is formed to be mounted on a bogie at a lower side bent at a right angle.

The a-shaped housing 40 mounted to the vehicle located at the rear side is fixed at both ends of the bent portion, and a circular through hole 42 is formed at the bent portion.

As shown in FIG. 3, a pair of disc-shaped laminated rubber parts 30a and 30b is fitted into and fixed to the through-hole 42 formed in the a-shaped housing 40.

The disc-shaped laminated rubber parts 30a and 30b are fitted and fixed to the a-shaped housing 40, and the fitting holes 35 are perforated in the center of the inner circumference of the disc-shaped laminated rubber parts 30a and 30b.

As such, when the disc-shaped laminated rubber parts 30a and 30b are fitted into the a-shaped housing 40, the fixing arm portions 24a and 24b protrude to both sides so as to be connected to the a-shaped housing 40. 20 is formed.

The coupling part 20 is fixed to face the vehicle that is connected to the vehicle in which the a-shaped housing 40 is fixed.

In order to fix the coupling part 20 to the a-shaped housing 40, the connection arm 22 and 23 are formed in the fixing arm parts 24a and 24b of the coupling part 20.

The position of the connecting holes 22 and 23 of the fixed arm portions 24a and 24b formed as described above, and the disc-shaped laminated rubber portion 30a fitted into the through holes 42 of the a-shaped housing 40; The position of the fitting hole 35 in 30b is fixed to be on the same line.

When the connecting holes 22 and 23 of the fixed arm portions 24a and 24b and the fitting holes 35 of the disc-shaped laminated rubber portions 30a and 30b are positioned on the same line, the fixing pin portion 31 ) Is fixed to penetrate from both sides to the center side.

The fixing pin part 31 is formed with a projection fitting part 34 protruding to one side, and a circular pushing surface 33 is formed on one surface of the projection fitting part 34.

The fixing pin 31 is preferably formed in a pin shape so as to be easily fitted, and a hole 37 is formed in the center thereof.

When the fixing pin 31 is fitted into the connecting holes 22 and 23 and the fitting hole 35 in this manner, the long bolts 38a are inserted to push the circular pushing surfaces 33 on both ends to each other. When fastening by fastening the 38b, the a-type housing 40 and the coupling part 20 are coupled to each other without being separated.

The operation relationship of the joint device of the railway vehicle of the present invention configured as described above will be described in detail as follows.

In the present invention, the coupling part 20 is fixed to the vehicle located at the front side, and the a-shaped housing 40 is coupled to the vehicle which is located at the rear side.

In addition, the lower end side of the a-shaped housing 40 is fixed to the upper side of the bogie is fixed to maintain the level of the vehicle.

The a-shaped housing 40 is fixed to the upper side of the bogie, while leveling the vehicle and at the same time smoothly bent when driving the curved section and at the same time smoothly cushioning when the traction force is generated.

Since the coupling part 20 and the a-shaped housing 40 are fixed by the long bolts 38a and the nut 38b to be fixed in a fitted state at both sides so as not to be separated from each other in a coupled state, the mutual coupling is not loosened.

In this way, between the coupling portion 20 and the a-shaped housing 40 coupled to be fixed by the long bolt 38a and the nut 38b so as to be cushioned with each other in order to prevent an impact generated during the towing between the vehicles. The disc-shaped laminated rubber parts 30a and 30b are sandwiched.

Therefore, when the engaging portion 20 connected to the vehicle located on the front side is pulled, the fixed arm portions 24a and 24b fitted into the connecting holes 22 and 23 of the engaging portion 20 are circumferential. The thickness is pulled in the thickness direction.

When pulled in the longitudinal direction by the fixing pin 31, which is fitted by the tension generated when the coupling portion 20 fixed to the vehicle is pulled in this way, to the fixed arm portion 24a, 24b of the coupling portion 20 Fixing pin portions 31 fitted in the formed connection holes 22 and 23 are simultaneously pulled toward the thickness direction.

Since the fixing pin part 31 is tightened inward by the long bolt 38a, the fixing pin part 31 is fixed without being pulled out in the longitudinal direction.

When the coupling part 20 and the a-shaped housing 40 are fixed by the long bolts 38a which are inserted into and fastened to the fixing pin 31, the shear force applied in the thickness direction is increased during the towing.

The long bolt 38a is fastened and fixed to the inner center so as not to fall out of the fixing pin part 31 in the longitudinal direction, but the connection holes 22 and 23 and the a-shaped housing 40 of the coupling part 20 are fixed. The fixing pin portion 31 fitted into the through hole 42 of the fixing bolt 31 has a bolt (33) on the outer side of the fixing arm portions 24a and 24b of the coupling portion 20 to increase the tightening force. 39).

When the force generated in the long bolt 38a fixed to the central axis of the hole 37 of the fixing pin 31 is transmitted to the fixing pin 31, the fixing arm portions 24a and 24b of the coupling portion 20 are provided. The disk-shaped laminated rubber portion 30a, 30b, which is fitted into the inner diameter of the through-hole 42 of the a-shaped housing 40 fixed to be positioned between the two, is pulled out.

At this time, the fixed arm portions 24a and 24b formed at both ends of the coupling portion 20 are positioned so that the a-shaped housing 40 is spaced apart therebetween by the conical shape of the projection fitting portion 34 therebetween. Since the fixed arm portions 24a, 24b and the a-shaped housing 40 do not collide with each other even if they are twisted to the left and right according to the curve of the rail, only the disc-shaped laminated rubber portions 30a and 30b are deformed and cushioned.

The disc-shaped laminated rubber parts 30a and 30b are buffered while being pressed in the direction in which a force is applied when the fixing pin part 31 is pulled.

In this way, the tensile force applied to the disc-shaped laminated rubber parts 30a and 30b is only in the thickness direction of the disc-shaped laminated rubber parts 30a and 30b when the entire vehicle and the rear vehicle travel in a straight line. Acts as a buffer.

In addition, when the rail on which the railroad vehicle is mounted according to the configuration of the connecting joint device of the present invention is in a straight section, the vehicle located at the rear is connected to the rear side when the vehicle is reversed without pulling the vehicle located at the rear side. When hitting, the fixing pin portion 31 fixed to the connecting holes 22, 23 of the coupling portion 20 in the opposite direction is pushed to the rear side.

When the fixing pin portion 31 fitted into the connection arm 22 of the fixing arm portions 24a and 24b of the coupling portion 20 is pushed to the rear side, the hole 37 formed at the inner diameter side of the fixing pin portion 31 is pushed. The long bolt 38a inserted into the through hole at the same time is also pushed backward while pushing the disc-shaped laminated rubber parts 30a and 30b fixed to the outer diameter side of the fixing pin 31 so as to push back. 30a) and 30b are also pushed back and are fully buffered.

When the disk-shaped laminated rubber parts 30a and 30b are pushed and cushioned, the applied force pushes the rear vehicle back while transferring the primary shock to the a-shaped housing 40 when the primary shock is buffered.

As described above, since the buffer is crushed while being deformed in the thickness direction of the disc-shaped laminated rubber parts 30a and 30b, the buffering force is high.

In addition, the circular laminated rubber parts 30a and 30b have a circular reinforcement layer formed therebetween to prevent easy breakage.

The circular reinforcing layers of the disc-shaped laminated rubber parts 30a and 30b are formed of a circular band plate and are not easily broken or broken.

As described above, since the disc-shaped laminated rubber parts 30a and 30b form circular bands in the thickness direction on the inner diameter side with a predetermined interval, the deformation is reduced by the force applied when the buffer is applied, and at the same time, the damage is prevented. Can be. That is, since the disk-shaped laminated rubber parts 30a and 30b are made of rubber, when the whole is made only of rubber, the strain is not only large, but also long-term use due to tearing or permanent deformation due to deformation. There is a problem.
Therefore, in order to prevent this, when a circular band is planted in the circumferential direction, the circular band is wrapped in a doughnut shape and supported while supporting the circular band, thereby preventing the deformation of the shape. (30b) is preferable.

In this way, the coupling between the a-shaped housing 40 and the coupling part 20 is connected to the disk-shaped laminated rubber parts 30a and 30b to be buffered, so that the buffering force can not only be increased, but also smoothly cope with the left and right or the up and down fluctuations. It is a structure that can be.

Therefore, when the vehicle equipped with the connecting joint device of the present invention passes through the rail of the curved section, the outer side of the curved section is a-shaped housing 40 and the coupling portion 20 while the disk-shaped laminated rubber portion ( 30b) is bent horizontally by the fixing pin portion 31 and the long bolt 38a fitted in the 30b), and the inner disk-shaped laminated rubber portion 30a on the contrary is fixed by narrowing the angle due to the curve of the rail. It narrows while compressing to the side of the projection fitting part 34 of the pin part 31. As shown in FIG.

When the curved section of the rail is bent to the outside, the disk-shaped laminated rubber portion 30b of the portion having the smaller radius of curvature of the rail is buffered while being narrowed toward the center of the circle.

Similarly, when the vehicle swings up and down along the rail of the vehicle, it is buffered by the disc-shaped laminated rubber parts 30a and 30b.

Thus, when the force is applied in the direction of the outer circumference from the center of the circle by using the disc-shaped laminated rubber parts 30a, 30b, the deformation is applied to the direction in which the force is applied along the direction of the rail curve in either direction of 360 degrees. Buffering is possible.

In addition, when the disc-shaped laminated rubber portion 30a, 30b fitted into the through hole 42 of the a-shaped housing 40 is worn, the long bolt 38a is fastened to push the fixing pin 31 together. Loosen the nut 38b and remove the bolt 39 holding the fixing pin portion 31 from the fixing arm portions 24a and 24b of the coupling portion 20, and then the disc-shaped laminated rubber portion 30a, 30b can be replaced easily.

By the connection joint device of the railway vehicle of the present invention as described above, it is possible to smoothly cushion the impact coming from the connection portion as well as smooth refraction during the passage of the curved section and tow between the vehicles at the same time.
