【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、鉄道車両に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a railway vehicle.
従来の鉄道車両では、例えば、特開昭５４−４４５７号
公報に記載のように５台車枠と車体間に設けられたばね
体のばね座は、ばね座中心と台車枠中心とがずれて台車
枠に固定されていた。In conventional railway vehicles, for example, as described in Japanese Patent Application Laid-open No. 54-4457, the spring seat of the spring body provided between the bogie frame and the car body is misaligned between the center of the spring seat and the center of the bogie frame. was fixed.
上記従来技術は、台車枠中心とばね座中心とがずれてい

１次支持体に相当し、車体が台車枠に相当するものにお
いても同様の問題が生じる。In the above conventional technology, since the center of the bogie frame and the center of the spring seat are misaligned, a large moment acts on the bogie frame due to the force applied to the center of the spring seat. Therefore, the bogie frame must be made strong. There is a problem that the bogie frame becomes heavy. Further, a similar problem occurs in a floating vehicle where the bogie frame corresponds to a primary support made of a magnet and the vehicle body corresponds to the bogie frame.
本発明の主な目的は、１次支持体若しくは台車枠にモー
メントが作用しないようにし、１次支持体若しくは台車
枠を軽量化できる鉄道車両を提供することにある。A main object of the present invention is to provide a railway vehicle in which moment is not applied to the primary support or the bogie frame, and the weight of the primary support or the bogie frame can be reduced.

ね座並進機構とを具備したものである。In order to achieve the above object, in a railway vehicle in which a bogie frame is supported on a primary support body via a primary spring body, and a car body is supported via a second and 32nd spring body on the bogie frame, Said 1
a spring seat connected to a secondary support or a bogie frame with a pin rotatable around a longitudinal axis; a primary spring body or a secondary spring body provided between the spring seat and the bogie frame or vehicle body; A spring seat translation mechanism is provided in parallel with the spring body between the spring seat and the bogie frame or vehicle body to vertically translate the spring seat.
１次ばね体若しくは２次ばね体のたわみと共に、ばね座
は、ばね座並進機構によって台車枠若しくは車体と平行
な関係を保ちつつ上下に移動する。Along with the deflection of the primary spring body or the secondary spring body, the spring seat moves up and down while maintaining a parallel relationship with the bogie frame or vehicle body by the spring seat translation mechanism.
１次支持体若しくは台車枠は、ばね座と前後軸まわりに

くは台車枠はピン結合によりモーメントを受けずにばね
座の上下移動と共に上下に並進移動する。The primary support or the bogie frame is connected to the spring seat with a pin that is rotatable around the front and rear axes, so the primary support or the bogie frame does not receive a moment due to the pin connection and can move along with the vertical movement of the spring seat. Translate vertically.

する。According to the above configuration, the superconducting coil l is the levitation coil 1.
When the magnet 2 is vertically displaced by receiving a steady or pulsating floating blade W from 4, or when the spring body 9 receives the upper and lower blades W, the reinforcing frame 3 of the magnet 2 is connected to the spring seat 8 by the pin 7. , so the center of the primary spring body 9 and spring seat 8 is at the pin 7.
Even if the reinforcing frame 3 is deviated from the position shown in FIG. 2 in the left-right direction, the reinforcing frame 3 only receives the upper and lower blades and is not subjected to any moment. This will be explained in detail in Section 5.

2F) force, which generates a force F on pin 1o'd. Since the forces F on pin 10'd are in opposite directions, 2
Give a moment of F12. A moment acts on the bogie frame 4, but no moment acts on the reinforcing frame of the magnet 2 with only the upper and lower blades W (assuming there is almost no frictional resistance around the pin 7), so the magnet 2 is made stronger by the moment. It is not necessary and can be made lighter. At this time, the spring seat 8 is vertically displaced by the spring seat translation mechanism 10 while maintaining a parallel relationship with the bogie frame 4, so the spring seat 8 is not tilted. pin 1
Due to the left and right elasticity of 0'b and 10'd, link 10
Very few pins 10'b for e to rotate in the vertical plane
, 10'd of horizontal movement is possible. Reinforcement frame 3 for magnet 2
Since it is connected to the bogie frame 4 by the parallel link 11, translation in the downward direction is possible. On the other hand, when the superconducting coil 1 receives a pulsating lateral force from the propulsion guide coil 15 and vibrates from side to side, the reinforcing frame 3 moves between the bogie frame 4 and the link 1 in the left and right direction.
Since the spring seat 8 and the pin 7 are elastically connected to each other by the pin lla of the spring 1, the spring seat 8 is cushioned.
