Description

  The present invention relates to a bogie for a railway vehicle and a railway vehicle using the same, and more specifically, four wheels on the front and rear sides, the axle of the wheel and the axle box bearing it, via the primary suspension on these axle boxes, A vehicle body having a bogie frame supported at both ends of the left and right side beams, and having a low floor passage portion lower than the wheels between the both ends of the side beams, and a high floor non-passage higher than the wheels of the vehicle body. Two cars, a rail car equipped with a vehicle body support part supported by a secondary suspension at the part and a vehicle supported by this car, are the leading vehicles, and support a car without a car without a car to support. It is related to the railway vehicles connected in this way.

  Such a bogie of a railway vehicle and a railway vehicle using the same are already known (see, for example, Patent Document 1 and Non-Patent Document 1). The railcar bogies disclosed in Patent Literature 1 and Non-Patent Literature 1 and the railcars using the railcars have a lower vehicle body in order to be barrier-free.

  For this purpose, the one disclosed in Patent Document 1 employs a system in which the front, rear, left and right wheels are independently driven by individual motors, and the motor is disposed outside the side beams and the wheels are disposed inside the side beams. The left and right wheels are separated from each other by an axle so that the floor of the vehicle supported by the carriage is provided with a low floor passage that has a width between the wheels and is lower than the center of the axle of the wheel. The two vehicles supported by the bogie are the leading vehicles, and the bogie-free vehicle without the bogie to be supported is suspended and supported, and the two bogie-free vehicles are used, and there is no bogie. The vehicles are suspended and supported by an intermediate vehicle supported by the carriage, and all the wheels are used as drive wheels.

On the other hand, as disclosed in Non-Patent Document 1, as shown in FIG. 4, like the railway vehicle disclosed in Patent Document 1, the leading vehicles A and B, the intermediate vehicle E supported by the carriages a, b and c, and the leading vehicle In a railway vehicle having a carriage-less vehicle C connected between the vehicle A and the intermediate vehicle E and a carriage-less vehicle D connected between the intermediate vehicle E and the leading vehicle B, a carriage c supporting the intermediate vehicle E is provided. The front and rear wheels c1 to c4 are driven wheels driven by individual motors m1 to m4, the front and rear wheels a1 to a4 and b1 to b4 of the carriages a and b are non-driving wheels, and the wheels c1 to c1 of the carriage c. c4 is arranged inside the left and right side beams c5 and c6, and between the left and right wheels c1 and c3, and between c2 and c4 is a low floor passage portion e1 of the intermediate vehicle E, and the wheels a1 to a4 and b1 of the carriages a and b. b4 is arranged outside the left and right side beams a5, a6, b5, b6, and the left and right side beams a , Between a6, has a right and left side beams b5, b6 between leading vehicle A, a low-floor passage portion A1, B1 of B. Moreover, since the low floor passage part E1 of the intermediate vehicle E is located on the motors m1 to m4 directly connected to the wheels c1 to c4, it is not obstructed by the wheels, but above the motors m1 to m4. It must be in the same position, and it has the same height as the low floor passage portions A1, B1, C1, and D1 of the other leading vehicles A and B, and the vehicles C and D without the bogie, and the bogie a of the leading vehicles A and B The left and right wheels a1, a3, a2, a4, b1, b3, b2, b4 are connected by axles a7, a8, b7, b8, respectively.
Japanese Patent Laid-Open No. 2006-142987 URL [http: // www. hiroden. co. jp / what / new / pdf / gm_max_press — 20041122. pdf]

  However, if the wheels of the leading carriages A and B are used as the driving wheels as disclosed in Patent Document 1, the overall structure including the wiring is complicated and heavy, resulting in manufacturing costs and running costs. It is expensive.

  On the other hand, the thing disclosed in Non-Patent Document 1 does not have such a problem, and the carriage c has a width of the low floor passage portion e1 of the intermediate vehicle E1 between the left and right wheels c1 and c2, and between the wheels c3 and c4. Although it can be sized correspondingly, two wheels c1, c3, their drive motors m1, m3, two wheels c2, c4, and their drive motors m2, m4 are arranged between the side beams c5, c6. Because it has to be, the bogie width increases and the weight increases. Moreover, since all of the wheels a1 to a4 and b1 to b4 are located inside the side beams as originally intended, the widths of the carriages a and b are not enlarged. The widths of the low floor passage portions A1 and B1 of the vehicles A and B are limited between the left and right side beams A5 and A6 located inside the wheels a1 to a4 and b1 to b4 and become smaller. Accordingly, in the leading vehicles A and B, the driver's seats A2 and B2 are provided so as to leave the entrance / exit passages A4 and B4 while being biased to the right and left in the traveling direction, and the entrances A3 and B3 are provided on the opposite side. The low floor passage portions A1 and B1 are connected at the same height to the driver's seat A2 and B2 side entrance and exit passages A4 and B4 and lead to the entrances A3 and B3. It becomes an obstacle. Furthermore, if the leading vehicles A and B are a type of railway vehicle in which a single bogieless vehicle C is connected between the leading vehicles A and B as shown in FIG. If the carriage c is used for one of the two, the vehicle is stable when traveling to the supporting vehicle side of the carriage c, but is unstable for traveling in the opposite direction. If the carriage c is adopted for both of the leading vehicles A and B, the problematic technique disclosed in Patent Document 1 is approached.

  The object of the present invention is to suppress the increase in size and weight of the bogie, so that traveling is stable in both forward and reverse directions regardless of whether the vehicle is connected in three or five, and it is connected to the getting-on / off passage A on the driver's seat side of the leading vehicle. An object of the present invention is to provide a railway vehicle capable of increasing the width of a low floor passage portion leading to a mouth.

  In order to achieve the above-described object, the bogie of the railway vehicle according to the present invention has four wheels on the front and rear sides, a wheel axle, a shaft box that supports the axle, and a primary suspension on these axle boxes, A vehicle body having a carriage frame supported at both ends of the left and right side beams, and having a low floor passage portion lower than the center of the wheel between the both ends of each side beam, is higher than the wheels of this vehicle body. In a railway vehicle bogie equipped with a vehicle body support portion supported by a high floor non-passage portion via a secondary suspension, one left and right wheels in the front-rear direction are non-drive wheels, and the other left and right wheels are drive wheels. It is characterized by being connected to individual motors.

  In such a configuration, the bogie of the railway vehicle is supported by the front and rear, left and right wheels at both ends of the left and right side beams of the bogie frame via the axle, the axle box, and the primary suspension, and between the two ends of the side beams. To support a vehicle body with a low floor passage part lower than the wheels through the next suspension with a high floor non-passage part higher than the center of the wheel of the vehicle body as a driving car, one of the left and right wheels in the front-rear direction is used. Although it is a driving wheel, the other left and right wheels are non-driving wheels, so the complexity, size, and weight of the structure are reduced, and the vehicle body is supported by this carriage to be the leading vehicle. Regardless of the number of connections, such as 3 connections where one vehicle without a truck is connected between the two cars, 2 cars without a truck and 5 cars where an intermediate vehicle supported by a truck connecting them is connected Both towed by one leading car and If the driving wheels and non-driving wheels of the bogies of both leading vehicles are symmetrically arranged in the front-rear direction, there is no difference in stable travel due to differences in the front-rear direction of travel. Make it. Further, with respect to the arrangement of the left and right drive wheels, the left and right motors, and the left and right side beams, the drive wheels follow the arrangement example in the carriage c of the intermediate vehicle E shown in FIG. By using it so that it is positioned closer to the front end side of the leading vehicle than the non-driving wheels, the low floor passage of the leading vehicle has a large width corresponding to the space between the left and right side beams, and the anti-driver's seat from the driver seat side biased in the left-right direction It can be made to connect with the boarding / alighting passage which led to the side entrance / exit.

  In the above, the driving wheel is further arranged outside the side beam, and the motor is installed near the driving wheel outside the side beam in a direction perpendicular to its axis, and protrudes from the driving wheel to the outside of the side beam. It can be connected to the axle through a transmission mechanism.

  In such a configuration, in addition to the above, the driving wheels and the motor are positioned side by side on the outside of the side beam, and these three do not overlap in the left-right direction. It is easy to suppress the space between the side beams located inside the drive wheels from being narrowed, the motor can be used without an axle, and the width of the low floor passage portion is not reduced and is preferably reduced. In addition, since the motor and the drive wheel are connected via a transmission mechanism, in addition to changing the direction of operation by the transmission mechanism, acceleration / deceleration of the rotational speed, absorption of vertical fluctuations of the drive wheel relative to the motor fixed to the side beam, etc. it can. At the same time, it is possible to cancel the disturbing moment without connecting the driving wheels with the axles with the standard gauge, and it is convenient to have a difference in the driving of the left and right driving wheels.

  In the above, further, the non-driving wheels are arranged inside the side beams, and the vehicle body support portions on the drive wheels side of the side beams are provided on the motor, and the vehicle body support portions on the non-drive wheels side of the side beams are The driving wheel side body support portion and the non-driving wheel side end portion may be provided at a lower height than the wheels.

  In such a configuration, in addition to the above, since the non-driving wheels are positioned inside the side beams, the non-driving wheels are positioned closer to the leading end side of the leading vehicle supported by the carriage than the driving wheels. By using it, the low floor passage part of the leading vehicle is limited to the extension of the bogie frame width by the side beam, and it has a large width corresponding to the non-driving wheels, from the driver seat side biased in the left-right direction to the anti-driver seat side It can be made to connect with the boarding / exiting passage leading to the boarding / exiting gate.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations as much as possible.

  According to the railcar bogie of the present invention, the left and right side beams of the bogie frame are supported by the front and rear left and right wheels via the primary suspension and between the both ends of the side beam from the center of the wheels via the secondary suspension. A vehicle that has a lower low floor passage is supported by a high floor non-passage that is higher than the wheels and can be driven independently. By making the wheels non-driving wheels, the complexity, size, weight, manufacturing and running costs of the structure are reduced, and one bogie-free vehicle is installed between the two leading vehicles that support the body with this bogie. Regardless of the number of connections, such as three connected articulations, two vehicles without trolleys, and five articulations connecting intermediate vehicles supported by trolleys connecting them, traction by one leading vehicle and the other With push by the top car of It is stabilized traveling in the suit look. Further, with respect to the arrangement of the left and right drive wheels, the left and right motors, and the left and right side beams, the drive wheels are not driven in accordance with the arrangement example of the intermediate vehicle E shown in FIG. By using it so that it is located on the tip side of the leading vehicle rather than the wheel, the low floor passage part of the leading vehicle has a large width corresponding to the space between the left and right side beams. It is possible to smoothly get on and off by connecting to a boarding passage that leads to the boarding gate.

  In addition to the above, the left and right widths of the carriage are reduced and the increase in size is suppressed by arranging the drive wheels and motors side by side on the outside of the side beams so that they do not overlap in the left and right direction. However, the space between the side beams positioned inside the left and right drive wheels is not narrowed, and the low-passage passage portion of the vehicle body can be made smaller and lower because the motor as well as the axle is not disturbed. In addition, by connecting the motor and drive wheels via a transmission mechanism, it is possible to change the operation direction, increase / decrease speed, absorb the vertical fluctuations of the drive wheels relative to the side-beam fixed motor, increase design freedom, and drive with standard gauge The interfering moment can be canceled without connecting the wheels with the axle, and it is also convenient to deal with a curve or the like by giving a difference in driving of the left and right driving wheels.

  In addition to the above, the non-driving wheel is positioned inside the side beam, and the non-driving wheel is positioned on the leading end side of the leading vehicle supported by the bogie relative to the driving wheel, so that the top width of the bogie is not particularly increased. The low floor passage of the vehicle is extended to the width of the bogie frame only by the side beam, and has a large width corresponding to the non-driven wheels, leading from the driver seat side biased in the left-right direction to the entrance / exit on the anti-driver seat side Connecting to the boarding / exiting passage makes it easy to get on and off.

  Hereinafter, a bogie of a railway vehicle according to an embodiment of the present invention and a railway vehicle using the same will be described with reference to FIGS. 1 to 3 for understanding of the present invention. The following description and illustration are specific examples of the present invention, and do not limit the description of the scope of the claims.

  As shown in the example shown in FIGS. 1 and 2 and the example shown in FIG. 3, the bogie 10 of the railway vehicle according to the present embodiment has four wheels 12 to 15 on the front and rear sides, and each axle 16 and the bearings. And a bogie frame 21 supported by both end portions 19a, 19b, 20a and 20b of the left and right side beams 19 and 20 via a primary suspension 18 on the shaft box 17. Further, the vehicle body 22 having a low floor passage portion 22a lower than the center of the wheels 12 to 15 between both end portions 19a and 20a, 19b and 20b of the side beams 19 and 20 is connected to the wheels 12 to The vehicle body support portions 19c and 20c are supported by the elevated floor non-passage portion 22b higher than 15 via the secondary suspension 23, and the railway vehicle 24 is configured together with the supported vehicle body 22. In particular, in the carriage 10, one of the left and right wheels 14 and 15 in the front-rear direction is a non-driving wheel, the other left and right wheels 12 and 13 are driving wheels, and the driving wheels are connected to individual motors 26 and 27. . The structure and number of the primary suspension 18 and the secondary suspension 23 are not particularly limited. Suspension structures may already be known, and typically include rubber, air, a coil spring single system, and a composite system thereof.

  As described above, the carriage 10 is supported by the left and right side beams 19 and 20 of the carriage frame 21 through the axle box 17 and the primary suspension 18 by the front and rear wheels 12 to 15 at the both ends 19a, 19b, 20a and 20b. Then, the vehicle body 22 having a low floor passage portion 22a lower than the center of the wheels 12-15 via the secondary suspension 23 between both end portions 19a, 19b of the side beams 19, 20 and 20a, 20b. Can be used as the driving vehicle. The vehicle 24 is configured to be supported by the high floor non-passage portion 22b higher than the wheels 12 to 15 of the vehicle body 22. In particular, since the left and right wheels 12 and 13 in the front-rear direction are used as driving wheels and the vehicle 24 is thus used as a driving vehicle, the other left and right wheels 14 and 15 are non-driving wheels. The complexity, size, and weight of the vehicle are reduced, so that both manufacturing and running costs can be suppressed, and the vehicle body 22 is supported by the carriage 10 to be the leading vehicles A and B as shown in the example of FIG. The connection number is such that three vehicles are connected to one vehicle C between two vehicles A and B, five are connected to an intermediate vehicle supported by two vehicles without a vehicle and a vehicle connected between them. Regardless, in both the front and rear directions, stable running is possible by a combination of traction by one leading car A or B and pushing by the other leading car B or A. In this case, if the driving wheels 12 and 13 and the non-driving wheels 14 and 15 of the carriages of the two leading vehicles A and B are symmetrically arranged in the front-rear direction as shown in FIG. Can be eliminated. Further, regarding the arrangement of the left and right drive wheels 12 and 13, the left and right motors 26 and 27, and the left and right side beams 19 and 20, the arrangement in the carriage c of the intermediate vehicle E shown in the drawings disclosed in Non-Patent Documents 1 and 2 is shown. By following the example and using the driving wheels 14 and 15 so as to be positioned closer to the leading ends of the leading vehicles A and B than the non-driving wheels 12 and 13 as in the example shown in FIG. The low floor passage portion 31 has a large width corresponding to the space between the left and right side beams 19, 20, and is connected to the entrance / exit passage 34 that leads from the driver seat 32 side biased in the left-right direction to the entrance / exit 33 on the anti-driver seat side. It is possible to get on and off smoothly.

  In the example shown in FIGS. 1 and 2, the driving wheels 12 and 13 are arranged outside the side beams 19 and 20, and the motors 26 and 27 have their axes close to the driving wheels 12 and 13 outside the side beams. The vehicle is connected to an axle 16 projecting from the drive wheels 12 and 13 to the outside of the side beams 19 and 20 via a transmission mechanism 25. In this way, the drive wheels 12 and 13 and the motors 26 and 27 are positioned outside the side beams 19 and 20 and arranged in the front-rear direction, and these three do not overlap in the left-right direction, so the left-right width of the carriage 10 can be reduced. As shown in FIG. 1, it is easy to suppress the narrowing between the side beams 19 and 20 located inside the left and right drive wheels 12 and 13, and the axles 16 can be made to have no connecting portion as well as the motors 26 and 27. The low floor passage portion 22a is suitable for making it large and low, and by omitting the connection of the drive wheels 12 and 13 by the axle 16, it can be made lower than the center of the wheels 12 and 13. Further, since the motors 26 and 27 and the drive wheels 12 and 13 are connected via the transmission mechanism 25, in addition to changing the operation direction by the transmission mechanism 25, the rotational speed is increased and decreased, and the motors are fixed to the side beams 19 and 20. Absorption of vertical fluctuations of the drive wheels 12 and 13 with respect to the motors 26 and 27 can be absorbed. At the same time, it is possible to cancel the disturbing moment without connecting the drive wheels 12 and 13 with the axle 16 with the standard gauge, and to drive the left and right drive wheels 12 and 13 corresponding to the curve. Also convenient.

  In the example shown in FIGS. 1 and 2, the non-driving wheels 14 and 15 are further arranged inside the side beams 19 and 20, and the vehicle body support portions 19c1 and 20c1 on the side of the driving wheels 12 and 13 of the side beams 19 and 20 are The vehicle support portions 19c2 and 20c2 on the non-driving wheels 14 and 15 side of the side beams 19 and 20 are not driven with the vehicle support portions 19c and 20c on the drive wheels 12 and 13 side. It is assumed that it is provided at a lower height than the wheels 12 to 15 between the end portions 19b and 20b on the wheel 14 and 15 side. Thus, since the non-driving wheels 14 and 15 are located inside the side beams 19 and 20, the carriage 10 supports the non-driving wheels 14 and 15 rather than the driving wheels 12 and 13 as shown in FIG. The lower floor passage portion 22a of the leading vehicle 24 is restrained from expanding the bogie frame width by the side beams 19 and 20 minutes, so that the leading vehicle 24 is positioned between the non-driven wheels 14 and 15. The boarding / alighting can be made smooth by connecting to the boarding / alighting passage 34 leading from the side of the driver's seat 32 biased in the left-right direction to the entrance / exit 33 on the counter-driver's seat 32 side.

  Here, the cart 10 of the present embodiment has the various configurations described in the examples shown in FIGS. 1 and 2 and the example shown in FIG. 3, and two of the vehicles 24 supported thereby are the leading vehicles. Thus, the carriage-less vehicle C without the supporting carriage or the carriage-less vehicles A, B,... Are suspended and connected, and the carriage 10 in the example shown in FIGS. , 14 is located on the vehicle front end side with respect to the drive wheels 12, 13, and the low floor passage portion 22a between the non-drive wheels 14, 15 is at the same height, and gets on and off the driver's seat 32 side in each leading vehicle 24. In the railway vehicle having a configuration connected to the passage 34 and leading to the entrance / exit 33 located on the opposite side of the driver's seat 32 on the left and right sides, or the cart 10 in the example shown in FIG. 12 and 13 are located on the vehicle front end side with respect to the non-driving wheels 14 and 15, and the respective driving wheels 13 The low floor passage portions 31 between 13 are at the same height and are located on the opposite side of the driver seat 32 which is connected to the entrance / exit passage 34 on the driver seat 32 side in each leading vehicle 24 and then approaches one of the left and right sides. The railway vehicle which leads to the entrance / exit 33 is provided.

  INDUSTRIAL APPLICABILITY The present invention is practically applied to a railcar bogie and a railcar using the same, and reduces the structure, size, weight, manufacturing and running costs of the bogie, and further, the body supported by the bogie to be the leading vehicle. The low floor passage portion limited by the space between the left and right wheels or between the side beams can be easily connected to the left and right widths extended by the passenger passage on the driver's seat side.
