Occurs. Then, the electromagnetic coil 1 and the rail 4 are attracted to each other by the magnetic force, and a frictional force is generated between the electromagnetic coil 1 and the rail 4 which are going to move in the vehicle traveling direction, which becomes a braking force of the vehicle.

The magnetic force generated by the electric current acts in the opposite direction to the magnetic force of the electromagnetic coil 1 with respect to the traveling direction of the vehicle, and the repulsive force becomes the braking force of the vehicle.

レールブレーキを提供することを目的としている。In the conventional adsorption type eddy current rail brake described above, when the magnetic poles of the electromagnetic coil are made of a material having high magnetic permeability such as pure iron, cast steel or steel, the coefficient of friction cannot be increased so much. However, there is a problem in that the rail head surface may be damaged by the rail braking operation because the rail is highly aggressive when it rubs against the rail. Further, when the magnetic poles are made of a sintered material or the like that does not damage the rail head surface, the friction coefficient can be increased, but the magnetic permeability is low, so the magnetic flux density flowing into the rail is low, and therefore the rail The problem is that the friction braking force of the brake is low. The present invention solves the problems found in the conventional adsorption type eddy current rail brake, in which a friction material is attached to at least one position between the magnetic poles of the electromagnetic coil and the outside of both end magnetic poles, and during operation of the rail brake. By adopting a structure in which most of the magnetic attraction force acting between the magnetic pole and the rail is applied to the friction material, it is not necessary to consider the magnetic permeability of the friction material, so there is no risk of damaging the rail head surface. Further, it is possible to easily select a friction material having a high friction coefficient. Since most of the magnetic attraction force acting between the magnetic pole and the rail is applied to the friction material, it is not necessary to consider damage to the rail head surface when the magnetic poles of the electromagnetic coil rub against the rail head surface. Is used as the magnetic pole material, and a high magnetic flux density can be utilized by directly contacting the rail. Accordingly, an object is to provide an adsorption type eddy current rail brake having a high friction braking force.
