考慮して列車の最高通過速度を決めてきた。(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.

、いまだに実層化されていない。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.

る。(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.

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.
