<p>1. Rail-brake magnet for electromagnetic rail-brake for rail vehicles, comprising a single or multi-section brake-shoe whose brake-shoe sections (1, 2), which are rigid or capable of limited intrinsic movement, are shaped like a yoke and are arranged next to one another in the longitudinal rail direction, projecting through the exciting coil (4) positioned with its axis at right-angles to the longitudinal rail direction, the end brake-shoe sections (2) having at their free face at least one first inclined plane (10) at least one pole side (16), which inclined plane (10) extends forwards and upwards from the horizontal sliding face (8) which can be deposited onto the rail surface, and which plane (10) forms an acute angle (alpha) of about 20 degrees with the rail surface, and there being provided a second inclined plane (12) which extends next to the sliding face (8) and for part of the longitudinal extension of the first inclined plane (10), the second inclined plane (12) extending forwards and upwards and bordering essentially laterally on the sliding face (8) and the first inclined plane (10) with lines of intersection (13, 14) at a slanting angle to the longitudinal rail direction, characterized by the combination of features - that the angle (alpha) between the first inclined plane (10) and the rail surface amounts to between 10 and 25 degrees, - that the second inclined plane (12) extends at an angle of between about 10 and 25 degrees to the rail surface and at a slanting angle to the outside of the pole side (6) of the end brake-shoe section (2) and reaches at least approximately over the full longitudinal extension of the sliding face (8), - that, when the inclined planes (10) and (12) are arranged at only one side, they are located at the pole side (6) facing the outside of the vehicle, and - that the sliding face (8) of at least that pole side (6) of the end brake-shoe sections (2) that is at the outside of the vehicle is wider than the corresponding sliding face of the centre brake-shoe sections (1).</p> |
