  • Patent number: 8942903
    Abstract: A method for predicting the temperature (Tin,p) of a wheel bearing of a vehicle wheel for a future moment (t+?tp) in relation to a present moment (t) or for a future time interval (t, t+?tp) in relation to a present moment (t), on the basis of a course of the temperature (Tin) of the wheel bearing in a past time interval (t??tb, t) in relation to the present moment (t), the predicted temperature (Tin,p) of the wheel bearing being determined from the sum of the temperature (Tin) of the wheel bearing at the present moment (t) and a corrective value (?TP) which is determined according to a change in at least one driving condition, such as the speed (?vtrain), and a change in the temperature (?Tb) of the wheel bearing within the past time interval (t??tb, t).

  • Patent number: 8874304
    Abstract: A method for monitoring the state of a bogie of a railway vehicle having at least one wheel set, wherein the wheels of the wheel set are rigidly connected by an axle and have an approximately conical wheel profile, and signals corresponding to a sinusoidal run of the wheel set of the bogie based on the conical wheel profile of the wheels are filtered out of signals provided by sensors disposed on the bogie. The frequency of the sinusoidal run is determined relative to boundary conditions, such as the prevailing vehicle speed, and compared to a save value or range of values for the frequency of the sinusoidal run typical for the prevailing boundary conditions, wherein the deviation of the measured frequency from the saved value or range of values for the frequency is monitored.
