2. Description of the Related Art In most of the bogies for railway vehicles currently in practical use, the wheel shafts arranged in front of and behind the bogie frame are independently compared in the longitudinal direction (vehicle traveling direction) and the lateral direction. It is elastically coupled firmly and is called a non-steering cart. In this type of bogie, since the front and rear direction supporting rigidity of the wheel shaft is large, excessive lateral pressure acts on the wheel flange and the rail when passing through the curve, promoting wear of both, and generation of squeak noise due to increased lateral pressure. Furthermore, there is a risk of derailment on board, which impedes driving safety and speed improvement on curved roads. Therefore, in order to improve the curve passing performance, for example, in JP-A-3-19729, etc., the front-rear direction supporting rigidity of the wheel shaft is reduced, and the yawing motions of the two pairs of wheel shafts have opposite phases. As described above, there is disclosed a railcar bogie having a steering device in which two pairs of wheel shafts are connected by a link mechanism. Further, in order to further increase the steering effect, for example, Japanese Patent Application Laid-Open No. 4-19264
Forced steering in which the vehicle body and the steering device are linked by a link to the gazette etc., the relative yawing motion of the vehicle body and the bogie frame is transmitted to the steering device via the link, and the steering shaft is steered by driving the steering device. A system trolley bogie is disclosed. However, in a conventional railcar bogie of a forced steering system in which a steering device is driven by a link or the like, the load applied to the links and the steering device for forcibly steering on a curved road, that is, the driving force is the front and rear wheel shaft support by steering. It increases in proportion to the direction spring force (spring constant of the front-back direction support spring of the wheel shaft x amount of deflection). Therefore,
The larger the steering amount, that is, the amount of deflection of the wheel shaft support spring in the front-rear direction, and the larger the front-rear spring constant, the larger the driving force. Since the steering amount is inversely proportional to the curve radius,
If the curve radius is sufficiently large and the front-rear direction supporting rigidity of the wheel shaft is small, almost complete steering can be performed with a small driving force. However, if the supporting rigidity of the wheel shaft in the front-rear direction is made small, the running stability against the snake action at high speed running is deteriorated, so there is a limit to the reduction of the supporting rigidity. Also, the curve radius is usually about 300 m or more on the main line, but there is also a small radius of about 100 m on the premises of the station. Therefore,
100 due to the support rigidity of the wheel shaft that is acceptable for stable running
In order to forcibly steer to a curve radius of m, it is necessary to design the link and the steering device so as to withstand a large driving force.

In the conventional steering cart, it is necessary to design the link and the steering device so as to withstand a large driving force when forcibly steering on a curved road with a small radius.

Further, since the vehicle body and the dolly are connected by a link or the like even when the vehicle is running straight, a minute driving force is also transmitted, and the vehicle body and the dolly are coupled to each other against mutual yawing vibrations to improve ride comfort.

For example, if the set value of the driving force is set to a value commensurate with the relative displacement amount between the vehicle body and the bogie frame when traveling the minimum curve radius (about 300 m) on the main line, the driving force will be increased on the curved road on the main line. Almost completely forcible steering is possible below a prescribed value, and when passing through a curved road with a small radius, it expands and contracts while keeping the driving force constant at the set value, allowing the bogie frame to yaw with respect to the vehicle body A curve can be passed without generating an excessive driving force.

FIG. 3 is a diagram showing a steering state of a steering carriage according to an embodiment of the present invention on a curved road. FIG. 3 shows the wheel shaft support springs 13 in the front-rear direction and the wheel shaft support springs 14 in the left-right direction, which are incorporated in the car case bodies 4a and 4b, and when the vehicle passes through the curved track R as shown in FIG. Car body 1
A relative yawing motion is generated between the bogie 2 and the bogie frame 2 around the bogie rotation center Q, and a relative displacement amount a is generated. The relative displacement amount a is transmitted to the vertical link 8 of the steering device 6 via the steering drive device 10, and the vertical link 8 is rotated about the rotation center O. This amount of rotation is also transmitted by the torsion shaft 9 to the steering device 6 '. Also, the vertical link 8
When the wheel rotates, the horizontal links 7a and 7b rotatably attached to the vertical link 8 rotate, and the wheel shafts 3a and 3b rotate in the radial direction of the curve by the displacement amount b.
3b is automatically aligned with the curved trajectory. At this time, a steering drive force (steering force) proportional to the spring force of the wheel shaft support spring 13 (the product of the deflection amount of the spring 13 and the spring constant) acts on the steering drive device 10 and the steering devices 6, 6 '. Therefore, the steering force becomes larger as the deflection amount of the wheel shaft support spring 13 becomes larger and the spring constant (rigidity) becomes larger. Further, since the steering drive force is inversely proportional to the curve radius, the larger the curve radius, the smaller the steering drive force. On the other hand, the steering drive device 10 acts as a rigid body when the steering drive force is below the set value, and when the steering drive force exceeds the set value, the steering drive device 10 expands and contracts while maintaining the drive force at a predetermined value. Therefore, by setting the set value of the steering drive device 10 to, for example, the maximum steering drive force during traveling on the main line, the steering drive device 10 during traveling on a curved line on the main line.
Acts as a rigid body and drives the steering devices 6, 6'in conjunction with the relative yawing movement of the carriage 2 with respect to the vehicle body 1,
As shown in FIG. 3, the wheel shafts 3a and 3b are steered so as to face the radial direction of the curve and smoothly travel on the curved road.

On the other hand, when the steering driving force exceeds the set value of the steering driving device 10 during traveling on a curve with a small radius such as on the premises, the steering device expands or contracts without transmitting the driving force to the steering devices 6, 6 '. Therefore, it is possible to prevent excessive driving force from being applied to the steering mechanism, and since the steering driving force is kept at a predetermined value, the curve steering performance will be slightly reduced, but it will be possible to smoothly pass through a curve with a small radius.

It does not interfere with high-speed driving performance and riding comfort on straight roads.

Holes 20a, 2
If a compressive force acts between 0b, the shaft 15 exerts a compressive force F in the direction of the solid arrow on the piston 16b. If the compression force F acting on the piston 16b is smaller than the expansion force (product of the fluid pressure and the cross-sectional area in the cylinder) due to the supplied fluid, the distance L between the pin holes does not change and the pin body is a rigid body with respect to the acting direction of the compression force. To work. On the other hand, when the compression force F acting on the piston 16b becomes larger than the expansion force by the supply fluid, the cylinder internal pressure is maintained at a constant value, so that the piston 16b moves in the cylinder 17 together with the shaft 15 and between the pin holes. The distance L becomes shorter. On the contrary, when a tensile force acts between the mounting pin holes 20a and 20b, the shaft 15
A bush 18 fixed to the piston 18 applies a compressive force F'in the direction of the broken arrow to the piston 16a. When this compression force F'is smaller than the expansion force due to the supplied fluid, it acts as a rigid body in the acting direction, and when the compression force F'becomes larger than the expansion force due to the supplied fluid, the piston 16a moves within the cylinder 17 together with the shaft 15. , The distance L between both pin holes becomes long. Therefore, by setting the pressure so that the expansion force by the supplied fluid becomes equal to the maximum allowable steering force, the steering device 6,
6'and the steering drive device 10 can be prevented from having an excessive driving force, and the steering device can be reduced in size and weight.
