Abstract
This invention relates to a device for determining lateral and/or vertical deviations in the path taken by a wheel at railway points or crossings. One of the aims of this invention is to provide data on the condition of such points or crossings, particularly as to the degree of their wear. Further, it is another aim of the invention to create a device which is easier to relate the signals from the sensors to the direction of the loads giving rise to these signals, and which at the same time is simpler and more economical to assembly while at the same time ensuring reproduceable results. According to this invention, a device for detecting lateral and/or vertical wheel path deviations at railway points or crossings, in which an actuating member (1) of the device works in co-operation with at least one sensor, particularly a resistant strain gauge, characterised in that the actuating member (1) is connected to at least one torsion rod (2), the torsion rod (2) is provided, in a manner known to those versed in the art, with four resistant strain gauges (3) in a circumferentially displaced pattern on its barrel or in a drilled hole, and the torsion rod (2) is disposed in the longitudinal direction of the rails and/or perpendicular thereto.
