題点があった。(Prior Art) An example of a conventional pantograph tilting device for a vehicle will be explained with reference to FIG. FIG. 2 is a front view of a conventional pantograph tilting device. In the figure, the pantograph l is supported by a link 7, and an air cylinder 9 that operates according to the output of a control device 8 that outputs curve information operates the link, forcing the pantograph in the opposite direction to the direction in which the vehicle body leans when traveling on a curve. It was intended to be moved. In this method, it is not possible to make the link too large due to the vehicle limit, so it may not be possible to secure a sufficient amount of relative movement between the vehicle and the overhead wire in the left/right direction, or if control fails. There were problems such as the risk of pantographs damaging overhead wires.

に親らない方式とすることとした。(Problem II to be Solved by the Invention) A method for solving the above-mentioned problem of the pantograph tilting device for a vehicle is to make the link supporting the pantograph as long as possible and create a link configuration that is advantageous to the vehicle limit, and when traveling on a curve. We decided to use a method that would ensure the necessary amount of relative movement between the vehicle and the overhead wire in the left and right directions, while at the same time avoiding a control system that could fail.

構造とした。(Means for solving the problem) The link that supports the pantograph has a two-stage link structure,
In order to make the link as long as possible, the link is extended to the inside of the car body, and dead weight is added to the bottom end of the link, thereby making use of the excess centrifugal force that acts on both the pantograph and the dead weight when driving around curves. The structure is designed to ensure the necessary amount of movement.

性を解消するようにした。In this way, by adopting a structure that also utilizes the centrifugal force acting on the pantograph, it is also possible to reduce the dead weight. Additionally, by utilizing natural forces such as excess centrifugal force, the risk of failout in forced control systems is eliminated.

FIG. 1 is a front view of the two-stage link type pantograph tilting device of the present invention. In FIG. 9, the same reference numerals as in the conventional example indicate the same members. A pair of links 3 supported at a point are provided, and a dead weight 4 is attached to the lower end of the link. In addition, this link and dead weight are arranged symmetrically with respect to the center of the car body, and at the same time, the links placed on both sides of the car body are connected by a cradle 5 at the top of the car body, and a pantograph 1 is installed in the center of the cradle. . With such a mechanism, the pantograph 1 moves in the same direction as the horizontal movement of dead weight due to centrifugal force. That is, when the vehicle body tilts inward in a curve, the pantograph moves in the opposite direction to the vehicle body tilt, so it is possible to reduce the amount of relative movement between the collector boat and the overhead wire in the left-right direction.
