Definitions

  • the invention relates to a method for determining service intervals in transmissions according to the closer defined in the preamble of claim 1.
  • DE 103 21 529 A1 discloses a method for determining service intervals in transmissions, in which characteristic values supplied by the internal combustion engine of the vehicle and by other components of the vehicle via the CAN interface are stored in the control unit of the transmission in order to evaluate them.
  • the values for the input torque and the input speed are stored and evaluated, taking into account efficiency maps of the transmission and the loss factors of the PTOs during the evaluation.
  • the evaluation is carried out in the form of a normalized diagram, which allows conclusions to be drawn on the duration of use as well as the application hardness of the vehicle. Here the number of load cycles is counted and added up. However, this leads to inaccurate statements about the condition of the lubricant.
  • the present invention has for its object to provide a method for determining service intervals in transmissions, in which the service interval can be determined exactly.
  • the state variables are determined during operation via sensors and stored in a memory device.
  • the oil temperature of the transmission is measured and in the storage device the Temperatures are stored in certain classes, whereby a temperature classification takes place.
  • the temperature in the transmission is measured at regular intervals and entered into a classification table. These values are evaluated according to the aging behavior of the lubricant as a function of the temperature and used for the indication of a necessary lubricant change.
  • the friction power is additionally determined at regular intervals and recorded in a classification table.
  • the friction power is preferably determined by the speed difference of the shaft driving the multi-plate clutch to the multi-disc clutch and the torque to be transmitted, which can be determined on the basis of a load detection. It is also possible to additionally consider the actuation times of the multi-plate clutches or brakes and / or the closing times. The values thus determined, which are entered in classes, are evaluated in accordance with the aging behavior of the lubricant as a function of the temperature and thus additionally taken into account for the indication of a necessary lubricant change.
  • the power which is transmitted from the transmission is additionally determined as a further criterion at regular intervals and recorded in a classification table.
  • the values determined are stored in classification tables, whereby the stored, classified values are compared with still permissible, stored values or lubricants and, if they are exceeded, a signal for changing the lubricant is output.
  • the contamination of the lubricant filter which is present for cleaning the lubricant in the transmission, also used to determine the lubricant change.
  • the measured values obtained are evaluated cumulatively and from this conclusions about the degree of soiling of the filter and from this about the usability of the lubricant are drawn.
  • the comparison of this data with previously empirically determined data additionally allows the indication of a necessary lubricant change.
  • the method of the temperature classification, the filter occupancy, the determination of the friction power and the determination of the transmitted load is considered as a whole and with previously empirically determined values and, depending on the composition of the individual values, a signal to change the lubricant output.
  • the signal for lubricant change can be made visually or acoustically, but it is also possible to output a progress bar on the current state of the lubricant.

Abstract

L'invention concerne un procédé permettant de déterminer des périodicités d'entretien, selon lequel des températures sont mesurées dans la transmission, à intervalles réguliers. Ces températures sont consignées dans des tables de classification et ces valeurs sont ensuite comparées, d'après les caractéristiques de vieillissement du lubrifiant, en fonction de la température. En cas de dépassement des valeurs autorisées, un signal acoustique ou visuel est émis pour changer de lubrifiant.
