Title:
EDDY CURRENT TYPE RAIL BRAKE DEVICE
Document Type and Number:
Japanese Patent JP2020010544
Kind Code:
A
Abstract:
To provide an eddy current type rail brake device in which the length in a longitudinal direction of a railway vehicle is shortened.SOLUTION: An eddy current type rail brake device 1 includes: a magnetic array 40; a support member 3; a magnetic electrode block 4; a plurality of pole pieces 5; and a slide device 6. The magnetic array 40 is arranged in one array in longitudinal direction. The magnetic electrode block 4 is adjacent to a permanent magnet 2 of one end of the magnetic array 40, and is a magnetic material. When viewing the slide device 6 from an upper direction of the eddy current type rail brake device 1, a plurality of permanent magnets is arranged so that one permanent magnet and one pole piece are overlapped in a brake state. In a non-brake state, two permanent magnets adjacent in the longitudinal direction are overlapped with one pole piece 5, and the magnetic electrode block 4 and the permanent magnet 2 adjacent to the magnetic electrode block 4 are overlapped with the pole piece 5 of one end in the longitudinal direction.SELECTED DRAWING: Figure 2
