Abstract

PURPOSE:To contrive the improvement of a speed passing through a curve by providing a moving device for steering the direction of a wheel so that its direction of rotation agrees with a tangential direction of the curve, in the case of a bogie having the right and left independent wheels which can be individually rotated respectively in the time of passing through the curve. CONSTITUTION:A rolling stock provides in its bogie two pairs of front and rear independent wheels 1, not connecting the right and left wheels by an axle, while a moving device 3, for steering the direction of rotation of each wheel to the tangential direction of a curve, in each journal box or the like. While providing a rotary plate 2, engraving a pulse generating piece, in the axle of each wheel, a pulse signal, generated by a sensor 4 arranged in the vicinity of the rotary plate 2, is input to a control unit 5 measuring a rotary speed of the wheel, while a moving amount for the moving device 3 to be moved and its timing or the like are calculated from a differential speed of the right and left wheels and their speed and fed out to the moving device 3 as the control information. And the wheel is rotated about the rotary center 6 in a manner wherein the direction of rotation of the wheel agrees with the tangential direction 9 of the curve.

Detailed Description of the Invention (Industrial Field of Application) The present invention improves running stability when a railway vehicle runs on a curve by allowing the wheels to smoothly pass through the curve, improving safety and improving safety while passing through the curve. This makes it possible to increase speed, reduce noise generated from the contact surface between the wheels and the track, and reduce the amount of maintenance between the vehicle and the track.

(Prior art) When a railway vehicle passes through a curve, in the conventional bogie structure, the rotation direction of the wheels does not match the tangential direction of the curve, so there is a gap between the wheels and the wheel contact portion of the track. An angle is created. Problems caused by this include expansion of the gauge due to lateral pressure generated between the wheels and the track, generation of squeaking noise, wear of the wheels and track, and repair of the track tightening device. For these reasons, the maximum speed at which trains can pass has traditionally been determined for each curve radius of the track, taking into consideration safety, economics, etc.

On the other hand, in order to shorten the time it takes to reach a destination, there has been a strong desire to improve the speed at which trains can pass through curves, and in Japan, self-steering bogies have been developed in terms of bogie structure. However, the running performance of this truck has not been sufficiently improved considering the complexity of the mechanism, and the above problems have not been solved, and it has not yet been put into practical use.

(Problems to be Solved by the Invention) In view of the current situation, the present invention solves the following problems that occur because the rotation direction of the wheels of conventional trolleys does not match the tangential direction of the curve. This aims to solve problems such as abrasion, damage, and noise caused to the track and wheels due to lateral pressure that occurs between the wheels and the track, and ultimately makes it possible to improve the speed at which trains pass through curves.

(Means for solving the problem) In order to solve the above problem, while the vehicle is passing through a curve,
This means that the rotation direction of the wheels is always steered in the tangential direction of the curve, and in conjunction with the adoption of independent wheels, it is theoretically possible to obtain better curve passage performance than normal wheels with left and right wheels integrated. . In other words, with normal wheels, even if the wheel rotation direction is steered in the tangential direction of the curve, slight slip may occur due to the difference in the radius of the curve because the right and left wheels are coaxially connected. In the case of independent wheels, such an event does not occur because the left and right wheels rotate independently.
