本発明は、車体開角運動抑制装置に係り、特に連接式浮
上車両の如く車体開角運動の大きい車両に適用するに好
適な車体開角運動抑制装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vehicle body opening angle movement suppressing device, which is particularly suitable for application to a vehicle with a large vehicle body opening angle movement such as an articulated floating vehicle. The present invention relates to a motion suppression device.
従来の装置は、一つの車体を二つの台車で支持し、両者

株式会社研有社発行 文献ＲＲＲ（１９８７年６月）第
２８頁から第２９頁のものが挙げられる。In the conventional device, one vehicle body is supported by two bogies, and a left-right damper is provided between the two bogies. An example of this type of device is the one published by Kenyusha Co., Ltd. in Document RRR (June 1987), pages 28 to 29.

さい角度変位によってダンパを敏感に作動させねばなら
ないという問題がある。In the above conventional technology, the wheels of the truck are guided by the rails,
In addition, since it has an inclined tread, the lateral movement of the bogie is attenuated and reduced (therefore, the lateral movement transmitted from the bogie to the car body is also reduced, so a small capacity lateral movement damper is installed between the bogie and the car body. However, in the case of a magnetically guided bogie where the bogie does not directly contact the rails and is guided, the lateral damping between the bogie and the track is very small, and therefore the lateral vibration of the bogie is large. h (achieves lateral vibration and increases the yawing of the bogie), which causes the lateral vibration and yawing of the car body to become extremely large in acceleration. To suppress this, the lateral movement damper between the bogie and the car body is made thicker. (However, there is almost no precision. Therefore, a large-capacity yaw angle damper mechanism is required that connects adjacent car bodies with pins and damps the relative yaw angle of both car bodies. This damper mechanism The capacity is several tens of times larger than the capacity of the lateral movement damper between the vehicle and the vehicle body, and there is a problem in that a damper with a diameter several times larger is required.Furthermore, even if the yaw angular acceleration is large, the yaw angle itself is a number of 1°. The problem is that the damper must be operated sensitively due to such a small angular displacement.
本発明の目的とするところは、小さいヨー角に対しても
十分大きなダンピングをうる車体開角運動抑制装置を提
供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle body opening angle movement suppressing device that can provide sufficiently large damping even for small yaw angles.
上記目的を達成するために、車体間を各軸まわりに回転
可能に連結体によってピン結合し、かつ、車体間の左右
両側にヨー角ダンパ機構、すなわち二つのリンク機構を
設けて、各リンク機構に普通サイズのダンパをＭＡＬ、
たものである。In order to achieve the above purpose, the vehicle bodies are pin-coupled by a connecting body so as to be rotatable around each axis, and yaw angle damper mechanisms, that is, two link mechanisms are provided on both the left and right sides between the vehicle bodies, and each link mechanism is MAL a normal size damper,
It is something that
車体間を各軸まわりに回転可能な連結体でピン結合する
ことにより各車体の左右変位を抑える。By pin-coupling the car bodies with a connecting body that can rotate around each axis, horizontal displacement of each car body is suppressed.
さらに車体間の左右両側に前後変位を拡大するリンク機

７のときには４９倍の減衰力が出せる。Furthermore, if a link mechanism is provided on both the left and right sides between the vehicle bodies to expand the longitudinal displacement, and a damper of normal capacity is attached to the tip of this link mechanism, the longitudinal displacement will be expanded by n times and the damping force of the damper will be 0n (C is the damper alone). ), and this damping force is then returned to the expansion mechanism and multiplied by C
It becomes n2. This damping force Cn2 acts on the left and right sides of the vehicle, and C
A damping moment with respect to yaw of n2·a (left-right distance a) acts on the vehicle body. Even if a damper with a normal capacity C can provide attenuation of n2 times. That is, n =
When it is 7, it can produce 49 times the damping force.

る。A vibration of yaw angular displacement θ21 θ22 is generated. Each vehicle body 2 is connected by a connecting body 9. When there is almost no left-right damping in parallel with the guide spring 4, such as in a magnetically levitated vehicle, the left-right displacement Y1 + yaw angle displacement θ1 of the bogie frame l is very large, so the left-right displacement of each car body 2 is y2□ + y2□, Yaw angular displacement θ2
1. θ22 also becomes very large. Even if the vehicle bodies are connected in the left-right direction by the connecting body 9 as described above, the yaw angular displacement θ21.
θ22 remains large. Since the yaw angle displacement between the vehicle bodies is θ3, the longitudinal displacement of the bracket due to θ3 is aθ3,
This displacement is magnified by a link mechanism consisting of the bracket 11, the vertical loft end, and the horizontal rod 16, and the longitudinal displacement of the damper 14 becomes aθ3·n. Therefore, the damper 14
A damping force of Caθ3·n is generated. On the other hand, this damping force applies a force of Caθ3·non to the bracket 111 by the lever consisting of the vertical rod 16 and the horizontal rod 16, so that a yaw reduction of 9%−1 of Caθ3nna=Cn2a2θ3 acts on the vehicle body 2. In other words, the yaw damping moment due to the yaw angle damper mechanism consisting of the link mechanism and the damper 14 is equal to the moment Ca when only the damper 14 is used.
It is n2 times 2θ3, and for example, when n = 5 to 10, the yaw damping moment can range from 25 to 100 times.

There is an effect that can be done.
