Definitions

  • the invention relates to a sensor arrangement comprising at least one sensor.
  • Running gears of rail vehicles often have devices with which a diagnosis or monitoring of the running gear itself and/or a track is carried out. This allows errors and damage to the running gear (e.g. a defective damper, etc.) or the track (e.g. a track geometry error, a broken track, etc.) to be detected and rectified in good time.
  • errors and damage to the running gear e.g. a defective damper, etc.
  • the track e.g. a track geometry error, a broken track, etc.
  • sensors provided for this purpose are arranged at the smallest possible distance from rails. This entails a great risk that obstacles or irregularities in the vicinity of the track (e.g. a branch of a tree lying on a track or a track defect) will hit the sensors (e.g. the branch or the track itself in the area of the track defect) and damage them.
  • LZB linear train control system
  • WO 2006/032307 A1 for example, is known from the prior art, in which a diagnostic device for checking routes (eg switches) is disclosed. Accelerations are detected by means of an acceleration sensor arranged on an axle box of a running gear of a rail vehicle. The detected accelerations are compared in an evaluation unit with acceleration limit values, with inspection steps being initiated on the roadway if limit values are exceeded. Furthermore, WO 2019/219756 A1 shows a method and a device for diagnosing and monitoring routes, with sensors being provided on a chassis of a rail vehicle.
  • EP 3 461 714 A1 discloses a running gear of a rail vehicle in which a clamping arrangement is clamped to a wheel set.
  • a carrying device is mounted on the clamping arrangement and is connected to a further chassis component (e.g. to a chassis frame).

  • the restoring device is designed to be resilient.
  • the resetting device is designed to be oscillating.
  • a spring-loaded reset device enables the sensor to quickly return to and maintain its nominal state after a deflection.
  • the sensor arrangement is further stabilized and thus spontaneous deflections of the sensor, which occur without the sensor colliding with an object, are avoided.
  • the restoring device is designed as a wire cable spring, the windings of which are on a first side and on a second side arranged opposite the first side with at least one profile which is aligned parallel to a longitudinal axis of the spring of the restoring device, which is on the first side with which is connected to at least one sensor and which can be connected on the second side in particular to a chassis of a rail vehicle.
  • This measure results in a particularly compact sensor arrangement, the sensor of which can be guided in a resilient manner, for example parallel to a longitudinal axis of the running gear, without devices for force deflection. On a lever arrangement etc. for storage of the sensor can be dispensed with.
  • a needs-based resistance of the sensor to movements can be achieved, for example, by selecting a wire rope spring with a suitable spring stiffness.

  • the first spring and the second spring can be designed as spiral tension springs, for example. Due to the first spring and the second spring and their crossed arrangement, the sensor is kept stable in its nominal state as long as no object hits it.
