本発明はボルスタレス台車のアンチローリング装置に関

７−２４２６５号公報に示すような構成のアンチローリ
ング装置が考案されている。[Prior Art 1] In recent years, bolsterless bogies have been used as bogies for railway vehicles, not only for commuter vehicles but also for express vehicles, high-speed vehicles, and other vehicles that require high curve passage speeds. For vehicles that pass through such curves at high speed, in order to reduce the rolling displacement of the vehicle due to insufficient cant,
An anti-rolling device having a configuration as shown in Japanese Patent No. 7-24265 has been devised.

という問題があった。In the above-mentioned conventional technology, with regard to the vertical damper provided between the car body and the bogie frame, sufficient consideration has been given to the ability to follow the relative rotational movement between the car body and the bogie when passing through a curve. Regarding the rolling device, sufficient consideration has not been given to its followability, and the anti-rolling device is the same as that of conventional bogies with pillow beams, and is not suitable as a mechanism that can tolerate relative displacement between the bogie and the car body in a bolsterless bogie. That was enough. For this reason, it is difficult to absorb the relative rotational displacement between the car body and the bogie that is required when the vehicle passes through a curve, and the anti-rolling device may be damaged or the anti-rolling device installed on the bogie to restrain the relative displacement may be difficult to absorb. There is a problem in that the angle of attack of the wheel axle onto the raceway becomes large, which may cause abnormal wear of the wheel flange.
本発明の目的は、車体と台車との相対回転変位を許容し

ことのできるボルスタレス台車のアンチローリング装置
を提供することにある。An object of the present invention is to provide an anti-rolling device for a bolsterless truck that allows relative rotational displacement between the vehicle body and the truck, suppresses displacement in rolling mode, and improves riding comfort.

される。[Means for solving the problem] The above object is to provide an arm that applies a torsion moment to a torsion rod that adds rolling rigidity, and when the deformation speed exceeds a certain value at one end of the arm, the shaking impact force changes to a large value. This is achieved by swingably providing a shock absorber having the characteristic, rotatably supporting the torsion rod on a truck or vehicle body, and swingably attaching the other end of the shock absorber to the vehicle body or vehicle body.

As it expands and contracts, it generates an extremely large resistance force against vibrations of several Hz caused by rolling of the trolley due to irregularities in the track, giving a torsional moment to the torsion bar of the anti-rolling device, and greatly increasing the amplitude of the rolling mode. to improve riding comfort.

装置１１を車体ｌと台車との間に設ける。The above configuration is what is called a bolster-less truck with no pillows, and the bolster-less truck uses the springs of the air springs 2 to move the vehicle body 1 horizontally, vertically, rolling, and
This will absorb displacement due to yawing. The spring constants of the air spring 2 in the vertical and horizontal directions are usually several 10.
This is small, on the order of 0 N/mm, and the lateral displacement of the vehicle body 1 due to lateral vibrations and rolling becomes too large, and the passengers' feet are lost. Therefore, an anti-rolling device 11 is provided between the vehicle body 1 and the bogie, which acts as a restraining force only in the vibration mode for low vibration and does not act as a restraining force in the vertical vibration or the horizontal vibration.

７に曲げが発生しないようにしである。As shown in FIG. 1, the anti-rolling device 11 is provided with a bracket 13 fitted with a bearing 12 on both sides of the side beam 4 of the bogie frame 3, and a torsion rod 1 is mounted on the inner ring of the bearing 12.
Arms 15 each having a certain length are fixed firmly to each end of the torsion rod 14 by a spline or other connection method so as not to move in the torsional direction of the shaft. A damper is installed between the arm 15 and the bracket 16 provided on the vehicle body l, as shown in FIG. 17, the center of the shaft hole of the attachment part of the damper 17 and the bracket 16 is provided in a direction perpendicular to the direction of relative rotation between the car body 1 and the truck, and the damper 17 and the arm 1
The damper 1 is attached to the damper 1 through a bearing 18 having a spherical bearing and an elastic body, so that the damper 1

It is only by the spring of 2.

えることができる。On the other hand, in a transition curve or a curved section provided on the track, a relative rotational displacement between the car body 1 and the bogie is required, but this movement requires a few seconds and is a very low vibration, so the characteristics shown in Fig. 2 are used. If the damper 17 is used, the restraining force required for relative rotational displacement is small and the necessary relative rotational displacement can be absorbed. On the other hand, if there is an irregularity in the track and rolling mode vibration occurs in the car body 1 (this frequency is large compared to the movement of relative rotational displacement between the car body 1 and the bogie), the By configuring the damper 17 as shown in FIG. 2, the tamper 17 generates a large resistance force, so the arms 15 provided on both sides of the torsion rod 14 move in opposite directions, and as a result, the torsion rod 14 has a torsional force. Torque is applied, a torsional spring constant is formed, the rolling rigidity is greatly increased, and rolling displacement can be suppressed to a small level.

It has the effect of improving comfort.
