Definitions

  • the present invention relates to a one-axis independent wheel bogie for a railway vehicle.
  • This invention is designed to suppress a zigzag motion (yawing oscillations of the bogie in a horizontal plane) during high speed running, and prevent the bogie from tumbling and turning in a pitching direction relative to a vehicle body. By so doing, the invention is intended to ensure a safe, stable run.
  • Driving bogies for many railway vehicles in current use employ integral type wheels composed of a right wheel and a left wheel coupled together via an axle.
  • a driving force from a motor installed on the bogie is reduced by a reduction gear, and transmitted to the integral type wheels to make a run.
  • a self-steering effect utilizing a slope of a wheel tread of the wheel makes a curved run possible.
  • an independent wheel driving bogie has been developed to adopt a flow floor structure or the like.
  • an axle is omitted to allow a right wheel and a left wheel to rotate individually and independently, and each wheel is driven by a separate motor.
  • a pair of wheels two wheels
  • each wheel is driven by a separate motor.
  • the right wheel and the left wheel rotate independently without being coupled together via an axle, but define a single axis as a pair.
  • this type of bogie is called "a single-axis" independent wheel bogie.
  • the bogie may turn (make a turning motion), with the turning angle of the bogie relative to the vehicle body exceeding a safety angle set for each of travel locations of the vehicle.
  • the vehicle can run safely without wheel derailment (a situation in which the flange of the wheel passes over a rail).
  • a turning angle which ensures such a safe run is designated as the "safety angle”.
  • a two-axis bogie (a bogie having two wheels arranged on the right side and two wheels arranged on the left side of a single bogie frame, and having two axes)
  • wheel derailment is minimally likely to occur because of a two-axis structure, even if the turning angle of the bogie relative to the vehicle body becomes great to a certain degree.
  • a single-axis independent wheel bogie by contrast, has a higher possibility, than the two-axis bogie, of a serious derailment accident because of a one-axis structure, if the turning angle of the bogie relative to the vehicle body becomes great to a certain extent.
  • the inventor decided to realize a curved run by employing a technique for a curved run based on the aforementioned method (i). While using this technique, the inventor tried to enhance the running stability of a one-axis independent wheel bogie. In detail, the inventor made efforts to suppress a zigzag motion (yawing oscillations of the bogie in a horizontal plane) during high speed running, and prevent the bogie from tumbling and turning in a pitching direction relative to the vehicle body. Through these measures, the inventor endeavored to ensure a safe, stable run.
  • the present invention has been accomplished in light of the above-described earlier technologies and the results of the technical studies. It is an object of this invention to provide a one-axis independent wheel bogie for a railway vehicle which ensures more stable running.
  • a first aspect of the present invention is a one-axis independent wheel bogie for a railway vehicle, which has a pair of wheels arranged for a single bogie frame, the wheel on a right side and the wheel on a left side being rotatable individually and independently, and which also has motors for driving the right and left wheels individually, the motor speeds of the respective motors being controlled to be equal to each other, the improvement comprising:
  • the centering mechanism may comprise a bent lever having a central portion pivotably attached to the vehicle body, a centering device interposed between one end side of the lever and the vehicle body, and a side rod for providing a connection between the other end side of the lever and the bogie frame.
  • the centering mechanism may comprise a bent lever having a central portion pivotably attached to the bogie frame, a centering device interposed between one end side of the lever and the vehicle body, and a side rod for providing a connection between the other end side of the lever and the vehicle body.
  • the damper mechanism may comprise a bent lever having a central portion pivotably attached to the vehicle body, a damper interposed between one end side of the lever and the vehicle body, and a side rod for providing a connection between the other end side of the lever and the bogie frame.
  • the damper mechanism may comprise a bent lever having a central portion pivotably attached to the bogie frame, a damper interposed between one end side of the lever and the vehicle body, and a side rod for providing a connection between the other end of side the lever and the vehicle body.
  • the damper mechanism restrains the one-axis independent wheel bogie from turning, and the centering mechanism returns the one-axis independent wheel bogie to a neutral position.
  • a zigzag motion (yawing oscillations of the bogie) does not occur in the one-axis independent wheel bogie during its high speed run, so that a safe, stable run can be made.
  • a second aspect of the present invention is a one-axis independent wheel bogie for a railway vehicle, which has a pair of wheels arranged for a single bogie frame, the wheel on a right side and the wheel on a left side being rotatable individually and independently, and which also has motors for driving the right and left wheels individually, the motor speeds of the respective motors being controlled to be equal to each other, the improvement comprising:
  • a third aspect of the present invention is a one-axis independent wheel bogie for a railway vehicle, which has a pair of wheels arranged for a single bogie frame, the wheel on a right side and the wheel on a left side being rotatable individually and independently, and which also has motors for driving the right and left wheels individually, the motor speeds of the respective motors being controlled to be equal to each other, the improvement comprising:
  • a zigzag motion does not occur in the one-axis independent wheel bogie during its high speed run, and a safe, stable run can be made.
  • the side rods of the centering mechanism are arranged at upper and lower positions while extending in the direction of advance of the one-axis independent wheel bogie.
  • the one-axis independent wheel bogie can be prevented from tumbling and turning in a pitching direction relative to the vehicle body, and can run safely.
  • Fig. 1 is a plan view showing a one-axis independent wheel bogie for a railway vehicle according to a first embodiment of the present invention.
  • Fig. 2 is a front view of the one-axis independent wheel.
  • Fig. 3 is a perspective view showing a side rod portion of the one-axis independent wheel bogie.
  • right and left wheels 3, 3 rotating individually and independently are arranged on a right side and a left side of a bogie frame 2 of a one-axis independent wheel bogie 1 for a railway vehicle. That is, a pair of the wheels 3, 3 are arranged on the single bogie frame 2.
  • a vehicle body 5 is borne via suspension springs 4, 4.
  • the one-axis independent wheel bogie 1 can make a turning motion (yawing motion) in a horizontal plane relative to the vehicle body 5 by a mobile center plate mechanism to be described later on.
  • reduction gear portions 6, 6 are provided in a right-hand portion and a left-hand portion of the bogie frame 2. These reduction gear portions 6, 6 are orthogonal reduction gears such as bevel gears, and have output shafts connected to the wheels 3, 3.
  • a control device 7 and main motors 8, 8 are provided on the vehicle body 5, a control device 7 and main motors 8, 8 are provided.
  • tachometers 8a, 8a for detecting the revolution speeds of the motors are attached to the main motors 8, 8.
  • the motor speeds detected by the tachometers 8a, 8a are fed back to the control device 7, which performs motor speed control so that the revolution speeds of both main motors 8, 8 equal.
  • Propeller shafts 9, 9 arranged on the right and left connect the main motors 8, 8 with the reduction gear portions 6, 6 to transmit the rotating force of the main motors 8, 8 to the reduction gear portions 6, 6.
  • the propeller shafts 9, 9 are splined in the axial direction to have an axially expansible structure.
  • control device 7 rotationally drives the main motors 8, 8 at equal speeds, and their rotating force is transmitted to the wheels 3, 3 via the propeller shafts 9, 9 and the reduction gear portions 6, 6, whereupon the wheels 3, 3 rotate and can travel on rails R.
  • a damper mechanism 10 is installed in a right-hand portion of the one-axis independent wheel bogie 1.
  • This damper mechanism 10 is composed of an L-shaped lever 11, a damper 12, and upper and lower side rods 13a and 13b as a pair.
  • the lever 11 has a central portion pivotably attached to the right-hand part of the vehicle body 5.
  • the damper 12 is interposed between the vehicle body 5 and one side 11a of the lever 11 while connecting the vehicle body 5 and the one side 11a.
  • the upper and lower side rods 13a and 13b are arranged so as to extend in a direction of advance of the one-axis independent wheel bogie 1, and are interposed between the bogie frame 2 and the other side 11b of the lever 11 while connecting the bogie frame 2 and the other side 11b.
  • rubber bushings 14a, 14b are interposed between the side rods 13a, 13b and the bogie frame 2, rubber bushings 14a, 14b are interposed to prevent high frequency vibrations.
  • the damper mechanism 10 Because of the presence of the damper mechanism 10, when the one-axis independent wheel bogie 1 is about to make a turning motion (yawing motion) relative to the vehicle body 5, a restraining force for restraining this turning motion is imparted to the one-axis independent wheel bogie 1 to make its turning motion difficult.
  • the side rods 13a, 13b of the damper mechanism 10 are arranged at upper and lower positions so as to extend in the direction of advance of the one-axis independent wheel bogie 1.
  • the one-axis independent wheel bogie 1 can be prevented from tumbling and turning in a pitching direction relative to the vehicle body 5.
  • This centering mechanism 20 is composed of an L-shaped lever 21, a centering device 22, and upper and lower side rods 23a and 23b as a pair.
  • the lever 21 has a central portion pivotably attached to the left-hand part of the vehicle body 5.
  • the centering device 22 is interposed between the vehicle body 5 and one side 21a of the lever 21 while connecting the vehicle body 5 and the one side 21a.
  • the upper and lower side rods 23a and 23b are arranged so as to extend in a direction of advance of the one-axis independent wheel bogie 1, and are interposed between the bogie frame 2 and the other side 21b of the lever 21 while connecting the bogie frame 2 and the other side 21b.
  • the centering mechanism 20 when the one-axis independent wheel bogie 1 makes a turning motion (yawing motion) relative to the vehicle body 5, a turning force can be imparted to the one-axis independent wheel bogie 1 in a direction in which the turning angle (yawing angle) of the one-axis independent wheel bogie 1 relative to the vehicle body 5 is reduced to zero. That is, the turning force can be imparted to return the one-axis independent wheel bogie 1 to a neutral position.
  • the side rods 23a, 23b of the centering mechanism 20 are arranged at upper and lower positions so as to extend in the direction of advance of the one-axis independent wheel bogie 1.
  • the one-axis independent wheel bogie 1 can be prevented from tumbling and turning in a pitching direction relative to the vehicle body 5.
  • a connecting rod 30 has a left side connected to the one side 21a of the lever 21, and has a right side connected to the one side 11a of the lever 11.
  • This connecting rod 30, the levers 11, 21, and the side rods 13a, 13b, 23a, 23b together make up a link mechanism, which serves as a mobile center plate mechanism. Because of this mobile center plate mechanism, the one-axis independent wheel bogie 1 can make a turning motion (yawing motion) in a horizontal plane relative to the vehicle body 5.
  • a zigzag motion (bogie yawing oscillations) does not occur in the one-axis independent wheel bogie 1 even during a high speed run.
  • the reason is that turning of the one-axis independent wheel bogie 1 is restrained by the damper mechanism 10, and the one-axis independent wheel bogie 1 is returned to the neutral position by the centering mechanism 20.
  • motor speed control is performed by the control device 7 so that the motor speeds of the main motors 8, 8 will become equal.
  • the wheel speeds of the right and left wheels 3, 3 equal, and when on a curved track, the one-axis independent wheel bogie 1 can make a curved run owing to a self-steering effect making use of a slope of the wheel tread of the wheels 3, 3.
  • the one-axis independent wheel bogie 1 runs on a small curve, for example, a very sharp small curve with R25 m which exists at only some locations of an operating route.
  • the resistance of the wheel (motor load) on an inner track becomes higher than the resistance of the outer wheel (motor load).
  • the revolution speed of the wheel on the inner track becomes smaller than the revolving speed of the outer wheel, thus making a run on a small curve possible.
  • the side rods 13a, 13b, 23a, 23b of the damper mechanism 10 and the centering mechanism 20 on the right and left are arranged at upper and lower positions so as to extend in the direction of advance of the one-axis independent wheel bogie 1.
  • tumbling and turning of the one-axis independent wheel bogie 1 in the pitching direction relative to the vehicle body 5 can be prevented on the right and left sides.
  • a zigzag motion during a high speed run can be suppressed, and the bogie can be prevented from tumbling and turning in the pitching direction relative to the vehicle body, so that a safe, stable run can be ensured.
  • a run on a curved track can also be made stably.
  • a one-axis independent wheel bogie for a railway vehicle according to a second embodiment of the present invention will be described with reference to Fig. 4, a plan view, and Fig. 5, a side view.
  • the second embodiment is different from the first embodiment in the state of mounting of a damper mechanism 10 and a centering mechanism 20, but is the same in other constitutions. Thus, only parts different from the first embodiment will be described below.
  • a lever 11 of the damper mechanism 10 has a central portion pivotably attached to a right-hand part of a bogie frame 2.
  • Upper and lower side rods 13a and 13b are arranged so as to extend in a direction of advance of a one-axis independent wheel bogie 1, and are interposed between a rod receiver 15 (vehicle body 5) fixed to the vehicle body 5 and the other side 11b of the lever 11 while connecting the rod receiver 15 and the other side 11b.
  • the other parts of the damper mechanism 10 are the same as in the first embodiment. That is, a damper 12 is interposed between the vehicle body 5 and one side 11a of the lever 11 while connecting the vehicle body 5 and the one side 11a.
  • a lever 21 of a centering mechanism 20 has a central portion pivotably attached to a left-hand part of a bogie frame 2.
