DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a bogie for a railway vehicle, and particularly to a bogie that can easily pass through curved roads and has good stability in meandering motion when traveling on a straight road at high speed.

Table of Contents 7 In order to prevent wear on the flange section, prevent squealing noise when passing on a curved road, improve safety against derailment, and increase running speed on a curved road, it is necessary to enable smooth turning on a curved road. At the same time, there is a strong desire for a bogie for railway vehicles that can run sufficiently stably and at high speeds on straight roads.

As an example of such a bogie, the slope of the tread where the wheels come into contact with the rail is increased, and the longitudinal support spring constant of the axle support bearing box with respect to the bogie frame is reduced, so that the outer track side and the inner track side can be easily adjusted on curved roads. The wheel axles can be turned along a curved line by having different wheel radii at the point of contact with the rigid rail, and the front and rear wheel axles are connected by a link device inside the bogie, which restricts the front and rear axles from turning along the curved path. However, there is one that improves the stability of meandering behavior when traveling on a straight road by preventing the front and rear axles from forming a rhombic shape due to relative displacement in the left-right direction.

FIG. 1 is a schematic diagram of an embodiment of the present invention. In the figure, 1 is the wheel, 2 is the bogie frame, 3 is the axle support bearing box, and 4 is the shaft spring.
D anti-camera rubber or a coil spring is suitable, and has a small spring constant in the front-rear direction (lateral rigidity of the shaft spring 4). Reference numeral 5 denotes a bearing box guard provided on the bogie frame 2, and clearances δ and δ' are provided in the front-rear direction between the bearing box 3 and the bearing box guard 5. 6 is a lock cylinder designed to prevent the generation of resistance force exceeding a predetermined value; one end is fixed to the bearing box guard 5 via anti-vibration rubber and 7, and the other end is fixed to the bearing box via a spherical bushing 8. It is attached to the stand 9. That is, the lock cylinder 6 is inserted between the bearing box 3 and the bogie frame 2 in the front-rear direction.

Figure 2 shows the relative displacement Δ in the longitudinal direction between the bearing box 3 and the bogie frame 2.
It shows the relationship between X and the forward resistance force F, which is a combination of the lock cylinder 6 and the vibration isolating rubber 7, and shows hysteresis as shown by the arrow when starting from the origin O of ΔX-0. The spring constant of the spring characteristics part is fixed as follows. Fmax is the maximum resistance force generated by the lock cylinder. Generally, the larger the Fma, the better the stability of the snake movement, but the worse the turning performance on curved roads, so Fmmx is selected as the minimum value necessary for the stability of the snake movement.

Fm a x can be made sufficiently smaller than the adhesion limit force between the wheel and the rail, and the clearances δ and δ' are set so that the wheel axle (the left and right wheels connected by the axle is hereinafter referred to as the wheel axle) follows the curve. The spring constant of the shaft spring 4 in the longitudinal direction should be made sufficiently small as described above, and the slope of the wheel tread should be selected so as to satisfy the following formula. For example, on a curved road, the wheel axle turns along the curved road, and the wheel 7 flange portion can smoothly travel on the curved road without contacting the rail.

As mentioned above, in order to improve the turning performance on curved roads, by reducing the longitudinal spring constant of the shaft spring and increasing the slope of the wheel tread, self-excitation, which occurs in railway vehicles when traveling at high speed on straight roads, can be achieved. Unstable snake behavior caused by vibration is likely to occur. This unstable meandering behavior is caused by the geometric meandering characteristic due to the slope of the wheel tread, and also by the inertial force of the wheel axle, etc., which causes excessive movement.
The inertial force can be effectively suppressed by providing a restoring force. As mentioned above, the present invention provides a resistance device having the characteristics shown in FIG.
This improves the stability of snake behavior by suppressing rotation around the vertical axis.

Furthermore, by providing the characteristics as shown in FIG. 2 due to the splashing action of the hydraulic oil in the lock cylinder, the vibration isolating rubber can be omitted.

Fig. 4 shows another embodiment of a resistance device having the characteristics shown in Fig. 2 using a spring made of anti-vibration rubber and dry friction. . Only the differences from FIG. 1 will be explained below. In Fig. 4, reference numeral 12 denotes a friction plate, which is preferably a plate spring made of iron plate with relatively low rigidity in the vertical direction and sufficiently large rigidity in the left-right and front-back directions.

13 is a vibration-proof rubber block, and iron plates are bonded to the upper and lower surfaces thereof. Reference numeral 14 denotes a holding plate, and a bolt 15 presses the vibration-proof rubber block 13 against the friction plate via the holding plate 14. The pressing force is determined so that the frictional force between the iron plate bonded to the vibration-proof rubber block and the friction plate 12 becomes F□8 in FIG. In this example, the stiffness of the vibration isolating rubber block 13 against shearing is equal to the spring constant of FIG. 2 equal to 1. Also in this case, by appropriately selecting the rigidity of the mounting portion of the resistance device, a special elastic body is not necessarily required to provide spring characteristics.
