Title: Electromagnetic attractive device for rolling stock
Inventor: MAEDA TOSHIO
IPC: B61H7/00
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To attract a track to a wheel to prevent the turnover of a rolling stock by providing a coil having an axis corresponding to the vertical line passing the contact between the wheel and the track on the wheel so as to surround the wheel without contact, and carrying a current to the coil. SOLUTION: A first coil 1 and a second coil 2 are mounted so as to surround a wheel 3 and a part of the brake pad 5 of a braking device 4. Since the braking device 4 has the structure of exhibiting a braking force by the contact of the brake pad 5 with the wheel 3, the coil cannot be located in the middle between the brake pad 5 and the wheel 3. Accordingly, the coil surrounds not only the wheel 3 but also a part of the brake pad 5. When a current is carried to the coil, the wheel 3 that is a magnetic body forms an electromagnet having the contact with a track 7 as one pole and the other end or the part farthest from the rail as another pole by the magnetic field emitted by the coil. In stopping a track horizontally inclined position, the wheel 3 is attracted to the track 7 by carrying the current to the coil to prevent the turnover of a rolling stock.
