Definitions

  • the invention relates to a rail vehicle with individual wheels which are held independently of one another in each case in bearings arranged outside and inside next to the wheel disc, with an inadmissibly high heating of the outer bearing being able to be monitored by stationary infrared devices.
  • E-PS 0 050 727 In bogie-like undercarriages, double-bearing single wheels are known (E-PS 0 050 727). With the help of the aforementioned stationary systems (infrared devices), the temperature of the outer bearings can be monitored, but these systems are not aligned with the inner bearings.
  • the invention has for its object to enable the temperature monitoring of the inner bearings with the same stationary systems in a simple manner.
  • the inner bearing is associated with a temperature sensor (thermistor) which, when the inner bearing is heated appropriately, ensures that an infrared sensor mounted externally in the height plane of the outer bearing is electrically heated.
  • a temperature sensor thermoistor
  • the stationary systems are also set up in such a way that the axis number of the passing train, in which there is a hot warehouse, is located and reported.
  • the infrared transmitter is arranged in the vicinity of the outer bearing.
  • independently rotatable individual wheels are held in bearings 2 and 3 arranged outside and inside next to the wheel disc 1, respectively.
  • the housing of the bearings 2 and 3 are designed in two parts in order to be able to easily install and remove each individual wheel.
  • a rod-shaped temperature sensor 5 (thermistor) is screwed into the housing 3a of each inner bearing 3 and closes a circuit 9 when an excessive bearing temperature is reached.
  • the heat radiation emitted by the infrared transmitter 6 is emitted by stationary infrared devices 4 next to the rails 10 received and sent as information to employees, for example in the next train station. Since the infrared transmitter 6 is located in the vicinity of the outer bearing 2, the staff are also informed about which axis of the arriving train contains the hot runner.
  • a relay 7 is arranged between the temperature sensor 5 and the infrared transmitter 6.
  • the source for the control current is 11, the one for the heating current is 12.
  • an acute hot runner is assigned a storage temperature of approximately 120 ° C.
  • the preliminary stage to an acute hot runner - a so-called warm runner - is supposed to be available from 70 o C.
  • the outer bearings 2 the location of both warm and hot runners is easily possible due to the proportional heat radiation.
  • the inner bearings 3 the aforementioned location is possible by, for example, two-stage design of the temperature sensor 5 with corresponding heating of the infrared transmitter 6 (70 o C or 120 o C).
  • two temperature sensors 5 and two infrared sensors 6 can be used, which are set to 70 ° C on the one hand and 120 ° C on the other.
