Abstract

PURPOSE:To eliminate unneeded steering functions to ensure a stabilized travel in a struck in which the position of an axle box is displaced in response to oscillating displacement between a car body and the truck by providing arm mechanisms for subtracting the right and left longitudinal displacements between the truck and the car body to detect only the amount of oscillation of the truck. CONSTITUTION:When a tractive force acts on trucks and a longitudinal displacement occurs between the trucks, displacement detecting links 15A, 15B are, for example, pressed to the right side to rotate clockwise to pull upper connecting links 19A, 19B to the right side. At the same time, lower detecting arms 17A, 17B press lower connecting arms 20A, 20B to the left side. Thus, truck-rotational angle detecting arms 12A, 12B are rotated clockwise, but steering command links 11A, 11B are fixed in the right and left direction not to act. On the other hand, when a car body comes into a curved track, and the center of the car body comes to the left side of a truck linkage mechanism, the steering command link 11A moves to the right side, the steering command link 11B moves to the left side, and the truck is steered through steering arms 6A, 6B and steering links 4A-4D.

In the axle load movement preventing bogie, the link mechanism of the traction device is characterized by the fact that the bogie and the vehicle body pitch each other around the position of the rail surface at the center of the bogie as the axle weight movement preventing bogie. On the other hand, in the case of bogies for electric trains, when the bogies are pitched, the height of the bolster anchor that connects the bogies to the vehicle body is placed at approximately the center of the axle box so that the bogie pitching does not cause longitudinal displacement. The longitudinal displacement on the floor of the vehicle and the upper part of the bogie is reduced. However, since the front-rear cushioning mechanism is provided between the bogie bodies, the front-rear displacement occurs even if there is a difference in the amount of movement.

Explaining the case where a longitudinal displacement occurs between the bogies, when the displacement detecting links 15A, 15B are pushed to the right by the longitudinal displacement, the displacement detecting links 15A, 15B move around the displacement detecting bars 16A, 16B. Rotate clockwise and pull the upper connecting links 19A, 19B to the right. On the other hand, since the displacement detection bars 16A and 16B simultaneously rotate clockwise, the lower detection arms 117A and 17B protruding downward from the displacement detection bars 16A and 16B push the lower connecting arms 20A and 20B to the left. become. By the above, the cart rotation angle detection arm 12Aa, 12B
Rotates clockwise, and the steering command links 11A and 11B connected to the center are fixed in the left-right direction and do not act. Therefore, a simple forward / backward movement between the bogies does not affect the steering link mechanism.

Next, as an example, a case where the body center is on the left side of the bogie link mechanism and the center of R from the wheels 1A and 1B moves to the right to enter the front side track is a bird's eye view. When the carriage 23 gradually swings in the clockwise direction and advances, the displacement detection link 15A is pushed and the displacement detection link 15B is pulled. Due to the displacement, the body carriage displacement detection arm 14A rotates clockwise around the displacement detection bar 16A, and the body carriage displacement detection arm 14B on the opposite side rotates counterclockwise around the displacement detection bar 16B and the lower connecting link. 19A moves to the right and upper connecting link 20B moves to the left. Next, the upper connecting link 20B moves to the left and the lower connecting link 20A moves to the right. With the above movement, the cart rotation angle detection arm
12A moves in parallel to the right and 12B moves in parallel to the left. The movement of the trolley rotation angle detection arms 12A and 12B causes the steering command link 11A to move to the right, and the steering arm 6A
Rotates clockwise, the steering links 4A, 4C are drawn toward the center of the bogie, and the gap between the axle boxes 3A, 3C becomes smaller. Next, the steering command link 11B moves to the left, the operation rudder arm 6B rotates counterclockwise, and the steering links 4B and 4D are extruded toward the outside of the carriage 23, and the gap between the axle boxes 3B and 3D becomes large. By the above operation, the gap between the axle boxes 3A and 3C is reduced and the gap between the axle boxes 3B and 3D is increased, so that the center lines of the axles 3A and 3B intersect on the front side of the carriage 23 and the carriage is centered on the intersection point. 23 starts to make a turning motion. Therefore, if the intersection point coincides with the R center point of the track curve, the steering function will be fully exerted when the diameter of the left and right wheels is proportional to the distance from the center of the curve due to the taper of the wheel tread. The conditions for the steering function to fully operate when the vehicle enters a curved road and the carriage 23 shakes its head will be described with reference to FIG. Here, R ...

With the vehicle body 21 of L riding on the curve of R and the carriage 23 swinging its neck in the direction of the curve, the wheels 1A to
When 1D is steered and the center line extensions of the axles 2A and 2B intersect at the center point O of the curve R, the carriage 23 is ideally steered. For this reason, the axle boxes 3A to 3D measure the amount of movement inside the carriage 23, and the amount of swing of the carriage detected by the body displacement detection arms 14A and 14B according to the swing angles of the body 21 and the carriage 23 will be examined.

Θ 2 = l / 2R ………………………… (2) From equations (1) and (2), the required movement X of the axle box is X = (l / 2R) × B / 2 = lB / 4R …… (3) Next, the body bogie displacement detection arms 14A and 14 by swinging the bogie.
The bogie swing amount Y detected at B is Y = Θ 1 × C / 2 …………………… (4) where Θ 1 is shown as follows Θ 1 = L / 2R …… ………………………… (5) (4) From formula (5), the bogie swing detection amount Y is Y = (L / 2R) × C / 2 = LC / 4R …… (6) where Y The ratio of the required movement amount X of the shaft box to the detection amount is X / Y = (lB / 4R) / (LC / 4R) = lB / LC (7) Next, Fig. 4 shows the length of the levers of links. of a is shown by l 1 to l 4, overall lever ratio M of the lever is M = (l 2 / l 1 ) × l 4 / l 3 = l 2 l 4 / l 1 l 3 .........

As described above, the steering mechanism of the present invention separates the movement between the carriage 23 and the vehicle body 21 into longitudinal displacement and swing displacement.
Since the bogie steering function acts only on the swing displacement,
It is possible to prevent abnormal vibration from occurring in the vehicle due to abnormal steering performed while the vehicle is traveling under various conditions. As another embodiment of the present invention, a rod mechanism shown in FIG. 5 will be described.
