| 摘要 |
The invention relates to a magnetic rail brake device of a railway vehicl e, comprising at least one brake magnet (2) which is provided with a magneti c coil element (8) that supports the at least one magnetic coil (9), and a h orseshoe-shaped magnetic core (6) having a yoke (28) and bearers (42a, 42b) protruding away therefrom. Pole shoes (16a, 16b) are embodied at the ends of the magnetic core which face a vehicle rail (1). The at least one magnetic coil (9) vertically engages the yoke (28) with the upper cover (30) and the lower cover (32) arranged between the bearers (42a, 42b). According to the i nvention, the cross-section of the at least one magnetic coil (9) in the upp er cover (30) is smaller heightwise (h) and wider (b) than the cross-section in the under cover (32). The height (h) of the cross-section of the magneti c coil (9) is measured parallel and the width (b) of the cross-section of th e magnetic coil (9) is measured transversally to a vertical central axis (38 ) of the brake magnet (2).
