となっている。2. Description of the Related Art A bogie for a conventional railroad vehicle is a Japanese Utility Model Sho 63-1594.
As shown in the specification of No. 92, an arm portion provided on the bogie frame,
This is a structure in which an arm portion provided at a lower portion of the vehicle body automatic coupling device is coupled by a coupling rod, and the traction force and the braking force of the truck are transmitted to the vehicle body through the coupling rod. This connecting rod is pin-coupled to absorb the vertical and horizontal relative displacement of the carriage and vehicle body.

部品強度に悪影響を与える。When the vehicle passes through rail seams or undulating rails, the bogie 2 may generate pitching vibration as shown in FIG. In the related art, when the bogie pitching vibration is generated, an axial force having the same cycle as the pitching vibration acts on the connecting rod 7 in the connecting rod 7. This axial force is transmitted to the vehicle body, and in the driver's cab, a feeling of being pushed up from below is felt, which deteriorates the riding comfort and adversely affects the strength of the bogie and vehicle body parts.

いる。Therefore, when the bogie 2 causes pitching vibration, in order to immediately suppress and damp this vibration,
As shown in FIG. 2, means for providing the shaft spring damper 10 between the bogie frame 3 and the shaft box 6 supporting the wheels 14 is used.

ばねダンパ１０を記号化して示したものである。However, the method of providing the shaft spring damper 10 between the bogie frame 3 and the axle box 6 to suppress the pitching vibration has the following drawbacks. This will be described with reference to FIG. FIG. 3 shows the shaft spring 13 and the shaft spring damper 10 symbolically in the structure shown in FIGS.

悪影響をまねくことになる。As shown in FIG. 3, when the vehicle passes over the undulating rail 12, the shaft spring damper 10 acts to suppress the relative displacement between the axle box 6 supporting the wheels 14 and the bogie frame 3. Therefore, the bogie frame 3 travels so as to follow the swell of the rail 12. Therefore, the vehicle body 1 and the bogie 2 cause relative motion, and as a result, the axial force still acts on the connecting rod 7, resulting in deterioration of riding comfort and adverse effects on component strength.
