Field of the Invention The present invention relates to a vehicle for rolling a railway vehicle in accordance with the radius of the curved section in order to enable the railway vehicle to run quietly, quickly and safely when passing through the curved section. The present invention relates to a railway vehicle provided with a device for turning in the traveling direction.

Due to the self-steering function of the wheel set based on the slope of the tread of the wheel, the bogie for the railway vehicle tends to rotate in a curved direction. On this occasion,
If the radius of the curve becomes small, the difference in wheel diameter cannot be sufficiently obtained, so that the flange of the outer track-side wheel of the bogie front wheel comes into a state of traveling while vigorously contacting the rail shoulder. At this time, the front axle of the bogie has an attack angle with respect to the rail, so that a large lateral pressure is generated between the wheel and the rail, and at the same time, a large slide is generated in the lateral direction. As a result, squeak noise is generated, and rail and wheel flanges are worn due to lateral pressure. In addition, the traveling speed may be limited in order to avoid the risk of derailment due to an increase in the lateral pressure.

る。As a measure for solving the problem in the curved section as described above, there are measures on the ground side and on the vehicle side. Among these measures, as a countermeasure on the ground side, a ground oiling device is installed at the entrance of the curved section, detects the passage of the vehicle, injects lubricating oil to the rail shoulder (corner part), and when the wheel flange passes, There is one that reduces the friction coefficient between the wheel and the rail by stepping on the injected lubricating oil and reduces the lateral pressure.

It takes time and labor. Lubrication can cause a spark of the brake to ignite. Difficult to set oiling amount. That is, if the amount of oil applied is large, there is a danger that the lubricating oil will turn on the treads of the wheels and the wheels will slide, or the braking performance will be impaired and the stopping distance will increase. Conversely, if the amount of oil applied is small, the effect is not obtained. There is a disadvantage that.

Things to do. The lateral pressure is reduced by forcibly steering the wheel axle according to the radius of the curve to reduce the attack angle (for example, JP-A-6-87446).
Softening the support rigidity of the axle box and improving the self-steering performance of the wheelset. Further, a method of controlling the yaw angle of the wheel axle by attaching an actuator from the bogie frame to the wheel axle to prevent the vibration of the vehicle (for example, Japanese Patent Application Laid-Open No. Hei 3-258655).
issue). By installing an oiler on the bogie side, detecting the curve and injecting oil onto the shoulder of the rail, lowering the coefficient of friction,
A device that reduces lateral pressure. The above-mentioned disadvantages of the countermeasures on the ground side can be solved except for those in which an oiler is installed on the truck side. In addition, even if the oiling device is installed on the truck side, the number of installed oiling devices is greatly reduced as compared with the one where the oiling device is installed on the ground side, so that the disadvantage caused by the large number of installed devices can be solved.

る。However, the above-mentioned countermeasures have the following disadvantages.
In the case of self-steering with the tread shape of the wheel of a circular shape, the wheel diameter difference is larger than that of a conical tread, but there is a limit, so there is little effect on a sharp curve road . In addition, in the one in which the support rigidity of the axle box is softened to improve the self-steering property of the wheel set, the running stability is reduced at the time of high-speed running on a straight road, so that the snake action is likely to occur. And the like have a limit in improving the curve turning performance, and those having a problem that the running performance is reduced contrary to the improvement in the curve turning performance.

In addition, there is a problem that a link configuration for steering the wheel set is complicated, and maintenance is increased. Further, there is a disadvantage that the number of actuators is increased due to control for each wheelset. Also, the one that forcibly steers the wheelset has no such drawbacks as
Since the wheel set is rotated with respect to the bogie (bogie frame), the running performance is degraded due to a change in the meshing state of the gears of the drive device while traveling on a curved road, or the braking force is applied during traveling on a curved road. In this case, the contact surface of the brake shoe against the wheel tread and the disc changes, so that the brake does not work evenly or the wheel axle position is determined with respect to the bogie frame when the brake is applied, so the steering force is reduced. There is a disadvantage that it becomes weak.

In addition, the present invention enhances the safety of a railway vehicle when traveling on a curve, and the reliability and economy of the device are superior to those of the prior art due to the simple configuration of the device.
