Fig. 5 A and Fig. 5 B are to schematically show the rail truck of present embodiment shown in FIG. 1 to FIG. 4 in curved path
The top view of situation when traveling.The case where Fig. 5 A in these figures indicates the curved path to turn left, Fig. 5 B indicate to turn right
The case where curved curved path.Referring to Fig. 5 A and Fig. 5 B, each composition of the vehicle of present embodiment when curved path traveling
The behavior of element is as so following.
In curved path, produced between bolster 56 (vehicle body 50) and bogie frame (the 1st framework 10 and the 2nd framework 20)
Raw opposite off-track displacement.For example, referring to Fig. 5 A, bolster 56 becomes relative to steering structure in the curved path of left-hand bend
Frame, the pattern yawed to the right relative to the direction of travel of vehicle.In contrast, in the curved path of right-hand bend, referring to figure
5B, bolster 56 become relative to bogie frame to the pattern of left drift.At this point, bolster 56 is relative to bogie frame, (the 1st is horizontal
Beam 12) it is yawed centered on central load bearing portion 30.
Firstly, referring to Fig. 5 A, the case where curved path of left-hand bend, is illustrated.As described above, bolster 56 by
The 1st interconnecting piece 52A for being configured at the right side of central load bearing portion 30 is connect with the 1st framework 10 (the 1st crossbeam 12), in being configured at
The 2nd interconnecting piece 52B in the left side of heart supporting part 30 is connect with the 2nd framework 20 (the 2nd crossbeam 22).Therefore, because bolster 56 is to the right
Yaw acts on the power towards rear to the 1st framework 10 via the 1st interconnecting piece 52A on right side, via the 2nd interconnecting piece 52B in left side
Power towards front is acted on to the 2nd framework 20.That is, the mutually opposing power on front-rear direction acts on the 1st framework 10 and the 2nd frame
Body 20.
At this point, as described above, the 1st framework 10 and the mutually bearing of the 2nd framework 20 are that can slide along front-rear direction.Cause
This, since above-mentioned power is respectively acting on the 1st framework 10 and the 2nd framework 20, the 1st framework 10 is rearward moved, the 2nd framework 20 to
Front is mobile.In short, generating, the 1st framework 10 is opposite with the 2nd framework 20 to be moved forward and backward.
Respectively elastically be supported on as a result, the rear ends 11a and 11b of the curb girder 11 of the 1st framework 10 axle box 33A and
33C takes behavior below.The axle box 33A of forward right side is supported in the 1st framework 10, also, is incorporated into and the by connecting rod 34A
2nd extension 23 of the 2nd different framework 20 of 1 framework 10.Therefore, the axle box 33A of forward right side is via connecting rod 34A by direction
The direction opposite with the moving direction of the 1st framework 10 is the power in front, is moved forwards.On the other hand, the axle box 33C of right lateral side
It is supported in the 1st framework 10, and is combined by connecting rod 34C with the 1st protrusion 15 of identical 1st framework 10.Therefore, after right
The axle box 33C of side is rearward moved together with the 1st framework 10.
In contrast, being respectively elastically supported on the axle box 33B of the rear ends 21a and 21b of the curb girder 21 of the 2nd framework 20
Behavior below is taken with 33D.The axle box 33B of front left side is supported in the 2nd framework 20, also, by connecting rod 34B be incorporated into
1st extension 13 of the 1st different framework 10 of the 2nd framework 20.Therefore, the axle box 33B of front left side is via connecting rod 34B by court
Opposite direction, that is, rear the power of the moving direction of 2 framework 20 of Xiang Yu, is rearward moved.On the other hand, the axle box of left rear side
33D is supported in the 2nd framework 20, and is combined by connecting rod 34D with the 2nd protrusion 25 of identical 2nd framework 20.Therefore,
The axle box 33D of left rear side is moved forwards together with the 2nd framework 20.
So, the shifting using the axle box 33B of the axle box 33A of forward right side movement forwards and front left side rearward
It is dynamic, the song for the curved path that the wheel shaft 31A of front side is shifted forwards with right side, left side rearward shifts, axis direction is turned left
The mode at rate center carries out low damage.On the other hand, the axle box 33C of right lateral side movement rearward and the axis of left rear side are utilized
The movement of case 33D forwards, the wheel shaft 31B of rear side is rearward shifted with right side, left side shifts forwards, axis direction is turned left
The mode of the center of curvature of curved path carry out low damage.In this way, in vehicle body 50 and the curved path according to left-hand bend
It generates opposite off-track displacement between bogie, generates that the 1st framework 10 is opposite with the 2nd framework 20 to move forward and backward, therewith
It links and the wheel shaft 31A and 31B of front and back is made to carry out low damage.
At this point, in the Tread brake device 40A and 40B of front side, the Tread brake device 40A of forward right side be held in
Therefore 2nd crossbeam 22 of 2 frameworks 20 moves forwards together with the 2nd framework 20.The Tread brake device 40B of front left side is protected
It is held in the 1st crossbeam 12 of the 1st framework 10, therefore, is rearward moved together with the 1st framework 10.In contrast, as described above with
The wheel shaft 31A displacement of front side, the wheel 32A of forward right side moves forwards, and the wheel 32B of front left side is rearward moved.Here,
The amount of movement of the Tread brake device 40A of forward right side forwards is roughly the same with the amount of movement of wheel 32A forwards.Front left side
The amount of movement of Tread brake device 40B rearward is roughly the same with the amount of movement of wheel 32B rearward.Each vehicle of front side as a result,
It takes turns at a distance from front-rear direction of the 32A and 32B with difference between corresponding Tread brake device 40A and 40B regardless of being oriented to such as
What is all constant.
On the other hand, in the Tread brake device 40C and 40D of rear side, the Tread brake device 40C of right lateral side is kept
In the 1st crossbeam 12 of the 1st framework 10, therefore, rearward moved together with the 1st framework 10.The Tread brake device 40D of left rear side
It is held in the 2nd crossbeam 22 of the 2nd framework 20, therefore, is moved forwards together with the 2nd framework 20.In contrast, as it is above-mentioned that
Sample is shifted with the wheel shaft 31B of rear side, and the wheel 32C of right lateral side is rearward moved, and the wheel 32D of left rear side is moved forwards.
Here, the amount of movement of the Tread brake device 40C of right lateral side rearward is roughly the same with the amount of movement of wheel 32C rearward.It is left
The amount of movement of the Tread brake device 40D of rear side forwards is roughly the same with the amount of movement of wheel 32D forwards.Rear side as a result,
Each wheel 32C and 32D on front-rear direction between corresponding Tread brake device 40C and 40D respectively at a distance from regardless of
It how all constant is oriented to.
Thus, as Tread brake device 40A, 40B, 40C and 40D, even if using universal product, each wheel 32A, 32B,
32C and 32D is at a distance from the front-rear direction respectively between corresponding Tread brake device 40A, 40B, 40C and 40D
It is how all constant regardless of being oriented to, therefore, braking ability can be fully maintained always.
In addition, the main motor 41A and 41B of front and back are held in the 1st crossbeam 12 of the 1st framework 10, therefore, with the 1st frame
Body 10 rearward moves together.In contrast, the geared system 42A of front side pacifies in the position adjacent with the wheel 32B of front left side
Wheel shaft 31A loaded on front side.The geared system 42B of rear side is installed on rear side in the position adjacent with the wheel 32C of right lateral side
Wheel shaft 31B.Therefore, as described above as each wheel shaft 31A and 31B of front and back are shifted, each geared system 42A and 42B of front and back
Rearward move.Here, each geared system 42A of each main motor 41A and 41B of front and back amount of movement rearward and front and back and
The amount of movement of 42B rearward is slightly different, but connects each connector (gear shape connector or flex plate shape connector) of their front and back
43A and 43B allows the difference of the amount of movement.Thus, as main motor 41A and 41B, geared system 42A and 42B and connector
43A and 43B, though using universal product, between each geared system 42A and 42B and respectively corresponding connector 43A and 43B before
How all constant distance in rear direction is regardless of being oriented to, and therefore, can maintain the smoothly drive of each wheel shaft 31A and 31B always
It is dynamic.
Then, referring to Fig. 5 B, the case where curved path of right-hand bend, is illustrated.In the curved path of right-hand bend,
Bolster 56 becomes the pattern to left drift relative to the case where bogie and curved path of above-mentioned left-hand bend on the contrary.Due to
Bolster 56 is to left drift, on the contrary, utilizing the 1st interconnecting piece 52A on right side to the 1st the case where curved path with above-mentioned left-hand bend
Framework 10 acts on the power towards front, acts on the 2nd framework 20 power towards rear using the 2nd interconnecting piece 52B in left side.Cause
This, the phase the opposite curved path moved forward and backward with above-mentioned left-hand bend that the 1st framework 10 is generated with the 2nd framework 20 the case where
Instead.As a result, the behavior of each component be only the case where the curved path of above-mentioned left-hand bend left and right it is opposite.
As described above, according to the present embodiment, in rail truck when curved path traveling, according to curved path
Opposite off-track displacement is generated between bolster 56 (vehicle body 50) and bogie frame (the 1st framework 10 and the 2nd framework 20).As a result,
It generates that the 1st framework 10 is opposite with the 2nd framework 20 to move forward and backward, links and can carry out the wheel shaft 31A's and 31B of front and back therewith
Low damage.Moreover, bolster 56 by central load bearing portion 30 with 1 dot point, therefore, bolster 56 is relative to bogie frame (the 1st crossbeam
12) it is successfully rotated along yaw direction.Thus, it is possible to fully reduce the transverse pressure on curved path.
In addition, each axle box 33A, 33B, 33C and 33D are flexibly supported on the 1st by corresponding axle box supporting arrangement respectively
Framework 10 and the 2nd framework 20.Also, it is opposite centered on the axis for allowing the 1st framework 10 and the 2nd framework 20 to link two fulcrums
Ground is rotated along pitch orientation.Therefore, in easement curve section, the tolerable front side generated with the torsion of track
Wheel shaft 31A and the opposite of wheel shaft 31B of rear side sidewinder displacement.Thus, it is possible to inhibit the wheel load in easement curve section
It changes.Especially, during rail truck is from outlet easement curve section to line interval, by the 1st interconnecting piece 52A and the
Connection spirit between the bolster 56 (vehicle body 50) and bogie frame (the 1st framework 10 and the 2nd framework 20) that 2 interconnecting piece 52B are carried out
Living, therefore, bolster 56 does not constrain that the 1st framework 10 is opposite with the 2nd framework 20 to move forward and backward.Therefore, the wheel shaft 31A of front side and
The wheel shaft 31B of rear side successfully reverts to the posture of standard.Thus, it is possible to be adequately suppressed the lateral pressure in easement curve section
The generation of power and the variation of wheel load.
