ピン１５ ａを介して台車枠４に支持さｎている。Next, the present invention will be explained with reference to Embodiment 1 shown in FIG. In the figures, the same reference numerals as in the conventional example indicate the same members. The eddy current brake device 110 is attached to the frame 9.
6 is installed. The auxiliary wheel 14 is connected to the link 13. It is mounted below the brake shear 16 of the frame 9 via a pin 15b corresponding to the brake shoe 16. A spring 18 is provided between the frame 9 and the link 13. The frame 9 is supported by the bogie frame 4 via a pin 15a by using an actuator.

る。When the eddy current acts, an adhesion force acts between the rail 11 and the brake force is generated, and the brake shoe 16 attached to the flea frame 9 is pressed against the auxiliary wheel 1 by the adsorption force.
It is pressed against 4 and the sticky brake is applied, 4 degrees. Note that the clearance between the brake shoe 16 and the auxiliary wheel 14 is adjusted by adjusting the thickness of the shim 17.

。According to such a configuration, since the eddy current brake device [10 is supported by the auxiliary wheels 14 other than the bogie component, the thin current brake device 10 is mounted on a spring other than the bogie, that is, a rail on the lower surface of the vehicle body 8. Even if it is provided in a portion opposite to 11, the same effect can be obtained. Furthermore, since the adsorption force during operation of the eddy current brake device W110 is borne by the W auxiliary wheel 14, the wheel axle
．． It is possible to prevent an increase in the load on the axle box 2 and the journal bearings inside the axle box 2. Therefore, since the unsprung weight can be reduced, wheel load fluctuations during high-speed driving can be suppressed. Further, in the above configuration, the brake shoe 16 is attached to the auxiliary wheel by the adsorption force generated when the eddy current brake device W110 is operated.
4, it is possible to obtain a larger deceleration force than the conventional eddy current type brake device.
